The APU of the PS4 is very powerful in performance, with 1.84T/s floating point GPU and 176GB/s 8GB GDDR5 Shared memory In terms of performance, it can be compared with high-end computers.^[1]

APU will use the x86 architecture for general computing CPU core It is integrated with programmable vector processing engine to make CPU more precise scalar Operation and large-scale parallel that only GPU has traditionally Vector operation Combine. AMD APU design combines CPU and GPU It brings unprecedented flexibility for software developers to develop new applications in the most suitable way. AMD APU connects the vector processing architecture of a programmable x86 CPU and a GPU on a single silicon chip through a high-performance bus, and both sides can directly read high-speed memory. AMD APU also contains some other system components, such as Memory controller , I/O controller, dedicated Video Decoder 、 display output and Bus interface Etc. The charm of AMD APUs is that they contain all the processing power composed of scalar and vector hardware.

PS4 APU framework diagram

The so-called APU is actually the abbreviation of "Accelerated Processing Unit", which is a new type of "Fusion" processor introduced by AMD that integrates x86/x64 CPU processing core and GPU processing core. Therefore, we can also find the term "Fusion Acceleration Processor" on the Internet. AMD has two kinds of APU platforms, one is the E-series entry-level APU that has been available in the market before, and the other is in 2011 European and American markets The A-series mainstream APU, which is officially launched, is divided into four series: A4/A6/A8/A10, which is commonly referred to as "Llano APU processor" (Rano APU processor).

Therefore, the APU platform of Series A is generally called the Llano APU platform. Of course, some people also call the Llano APU platform the GPU integrated with APU“ Lynx Platform "（ Lynx Platform).

AMD believes that the integration of CPU and GPU will be carried out in four steps:

X1 APU framework diagram

The first step is physical integration, which integrates CPU and GPU on the same silicon chip, and uses high bandwidth Internal bus Communication, integrated high-performance memory controller software system facilitate Heterogeneous computing 。

The second step is called Optimized Platforms. The interconnection interface between CPU and GPU is further enhanced, and unified bidirectional Power management , GPU also supports advanced programing language This part is the most critical.

The third step is architectural integration to achieve a unified CPU/GPU Addressing space , GPU can be paged system memory GPU hardware is schedulable and CPU/GPU/APU memory is coordinated, which has been initially completed in APU.

The fourth step is architecture and system integration (Architectural&OS Integration), the main features include GPU computing environment switching, GPU graphics first computing, independent graphics card PCI-E Collaboration Task parallelism Running real-time consolidation, etc Microsoft , ADOBE, etc Industry software The giant keeps communicating.

APU is AMD Most of the company's research results on fusion technology over the years in traditional computing Floating point operations They all leave the CPU and turn to the GPU that is good at this. GPU is no longer just a game tool, and hybrid computing will shine. In the near future, the concepts of CPU and GPU will also gradually blur, as AMD has advocated: The Future is Future.

performance prediction

HD Graphics 3000

We can see the performance of Trinity APU processor from the mobile platform displayed by AMD. AMD has run the new DX11 on the laptop equipped with Trinity APU《 Deus Ex: Human Revolution 》To facilitate understanding, AMD also compared Intel's Sandy Bridge platform (the mobile Sandy Bridge is built with HD Graphics 3000) Anti-Aliasing （ MLAA ）、 Texture filtering , screen Ambient Occlusion （SSAO）、 Depth of field (DOF), post processing Surface subdivision After special effects and technologies, Trinity APU platform runs more smoothly, while Sandy Bridge platform will show obvious Caton phenomenon 。 with PCMark Vantage 、 3DMark Vantage By measuring the performance, the processor performance and graphics performance of the desktop version can be improved by up to 30% compared with the Llano APU, while the laptop version can be improved by up to 25% and 50%. Trinity APU will target Windows 8 The operating system is specially optimized and new video processing capabilities are introduced, especially video compression The engine "VCE" is targeted at Intel QuickSync transcoding engine.

Power consumption and endurance

as for Battery endurance ，AMD Internal test The answer is: the Windows desktop is idle for 12 hours and 28 minutes, playing DVD Standard definition movie 7 hours and 15 minutes, playing BD Blu ray HD movie 4 hours, 2 minutes, running 3DMark 06 Test for 3 hours and 20 minutes.

This generation of Llano APU did not play its due role due to shortage - Fusion APU was officially released on March 1, 2011, the mainstream Llano APU was officially released on June 1, 2011, and in mid September, it belonged to A series APU A8 -3850 and A6-3650 We haven't seen the goods in the store yet, at least we haven't seen the goods in Zhongguancun store. Under the condition that Sandy Bridge completed the distribution early and started the publicity, how many more Llano APUs have Performance space It is not known yet. Maybe the real energy of APU can burst out on Trinity APU. New bulldozer architecture processing core and more emphasis on integer computing performance General calculation The new VLIW4 architecture graphics core will make the new generation Trinity APU more attractive, and the power of the fusion concept first proposed by AMD will also be released at that time.

APU and integration

differ Bulldozer Llano APU does not use a new kernel architecture, even unlike Brazos At least the processor of APU platform is the new Bobcat architecture, which is mainly K10 processor, DX11 graphics card (and North Bridge Chip), but obviously not 1+1=2 So simple. The problem faced by Llano APU is not only to avoid 1+1<2, but also to strive to achieve 1+1>2.

Llano APU design goal There are mainly the following:

－ Comprehensive performance of CPU and GPU : Provide the best CPU and GPU performance at the same time.

－ Independent graphics card level GPU experience : Complete DX11 and function set; Drag transcoding and Aero Effect, etc Windows 7 Experience.

－ Unique dual graphics card technology : Provides additional performance with the AMD Radeon standalone graphics card.

－ Next generation video acceleration : That is UVD 3 engines, innovative display and image quality functions, and higher bandwidth.

－ Industry and open standard computing API support : Mainly OpenCL 、 DirectCompute , simultaneous data Transmission delay Lower.

－ 3D stereo : Support HD3D, including Blu ray 3D, DisplayPort 1.1 DP 1.2）、 HDMI 1.4a。

It can be seen that five and a half of the six goals are related to GPU, and only half are related to CPU. The focus of Llano APU is self-evident, which is also consistent with the name of platforms such as AMD VISION.

APU architecture (3 sheets)

Llano APU chip is manufactured by GlobalFoundries 32nm HKMG process, and is divided into two versions. One is the complete version, integrating 1.45 billion transistor , core area 228 square millimetre , also called Big Llano or Llano 1; The second is the compact version, which integrates 758 million transistors. The core area is unknown for the time being. It is also called Small Llano or Llano 2. Both adopt the new micro PGA encapsulation interface Socket FS1772 pin without top cover, Pin spacing 1.2192 mm, Chip size 35 × 35=1225mm2.

From all aspects, the first full version of the Llano APU was released, and the dual core version was also shielded by the quad core Thermal design power consumption It is also high. I don't know when we will see the native dual core version, but AMD revealed that it will launch a new version that does not require fan cooling in the near future low power consumption The model, I guess.

Similar to the previous Brazos APU, the Llano APU also integrates the following modules on a single silicon chip: x86 Processor core 、 L2 Cache 、 DDR3 memory Controller, graphics SIMD Array (i.e. GPU) Display controller , UVD decoding engine PCI-E controller 。 From the two figures below, you can see the distribution position and relative size of each module.

Llano APU integrates so many functional module How to ensure the high-speed interconnection between them, so as to keep the whole in the best state at any time and avoid any potential bottlenecks, is undoubtedly the most critical point in the APU design process, and is also the basic premise for achieving the effect of 1+1>2. AMD has obviously made great efforts in this regard, for example, specially designed a new Fusion Compute Link to North Bridge Module, GPU IO The input and output are connected in series, allowing the GPU to access the consistency cache/memory. At the same time, a Radeon Memory Bus is built between the GPU and the North Bridge（ Video memory GPU access through high-speed bandwidth system memory 。

In the final analysis, APU does not simply integrate the CPU and GPU into one silicon chip, otherwise it will not take AMD more than three years to modify the design repeatedly to finally Cultivate the fruit 。

CPU and Turbo Core

The processor part of Llano APU comes from Stars architecture, commonly known as K10 architecture, and Phenom II/Athlon II series is of the same origin, which is more exactly equivalent to the previous Phenom II Mobile series on the mobile platform, with 128 bit floating-point Unit L1 cache (64KB+64KB per core), L2 cache (1MB per core), but none L3 cache 。

Of course, everything is not completely copied. except manufacturing process from 45nm Improved to 32nm for more efficient transistor control Integration , core area, frequency and power consumption, support C6 The power status has also been greatly optimized in detail, including higher capacity L2 cache, improved hardware prefetching, larger window size, and hardware Splitter , support the intelligent overclocking technology of the second generation Turbo Core, and finally Clock cycle The number of instructions has increased by more than 6%.

Introduction to Turbo Core 2.0 (8 sheets)

The Turbo Core, whose official Chinese name is:“ Intelligent overclocking ”。 This technology first appeared on the six core Phenom Ⅱ X6 series, and now it has evolved to the second generation, supporting the whole range from bulldozer to APU Series of products , but as of 2011, there is basically no software tool The dynamic frequency of Turbo Core can be monitored in real time, only AIDA64 Incidental CPUID Not bad.

We know that the actual power consumption of processors under different loads varies greatly, and there is still some room for the maximum thermal design power consumption. On the other hand Multi core The processor is active in different application environments Number of cores It is also different, which results in that processor resources cannot be fully utilized, resulting in waste.

The solution is based on power consumption monitor The power consumption of each processor core is measured in real time, summarized by Beiqiao, and then uniformly reported to the P-State power state manager, who then allows each processor core to run under the appropriate power state, or speed down or speed up, especially when speed up, it can exceed the original frequency for a short time, and ensure that the overall thermal design power consumption is never exceeded.

The innovation of AMD Turbo Core is the use of digital advanced Power management （ APM ）Compared with the analog temperature and current monitoring methods in similar technologies, the module can provide highly sensitive power management, accuracy Higher, complete Repeatability 。

More importantly, the Turbo Core will automatically coordinate the CPU and GPU, so that those who need more resources can obtain higher speed. When the GPU is idle, it will significantly reduce its frequency to increase as much as possible CPU frequency 。

If a heavy graphics or video task is encountered, the GPU will get a higher priority, and the CPU will take the second place.

If the GPU performs light load tasks such as DVD video playback, the acceleration space left for the CPU should exclude that part of the GPU from the overall thermal design power consumption.

In extreme cases, if both CPU and GPU are facing busy tasks, or need to work together for OpenCL APP Accelerate the calculation. At this time, the CPU and GPU will be accelerated at the same time, or even exceed the design power consumption limit in a short time. Then, reduce the CPU frequency and power consumption (GPU remains unchanged) according to the situation to ensure that the core temperature is not too high. This is the second generation on Sandy Bridge Turbo Boost Some similarities.

Accelerate processor

In terms of memory support, Llano APU mobile version supports dual channel DDR3 SO-DIMM, one for each channel Memory module , that is, only two memories can be inserted in total, with a maximum capacity of 32GB. In terms of frequency and voltage, the standard version of DDR3 has a maximum of 1600MHz, a voltage of 1.5V, and the low-voltage version of DDR3L has a maximum of 1333MHz, a voltage of 1.35V, and a bandwidth of 25.6GB/s.

The desktop version of Llano APU supports dual channel DDR3 DIMM There are two memory modules per channel, and a total of four memory modules can be inserted. The maximum capacity is 64GB. It supports 1.35V DDR3-1333, 1.5V DDR3-1866, and the maximum bandwidth is 29.8GB/s.

Since CPU and GPU are "in the same room", it is inevitable to compete for resources (in fact, APU Memory bandwidth Of dependence Is really strong), so AMD will Memory controller The bandwidth between the memory controller and the memory is four times that of the previous generation platform, and higher than that between the memory controller and the memory.

DX11 GPU

GPU architecture (3 sheets)

This part is the focus of Llano APU. its Development code It is "Sumo" (Sumo), originated from Redwood core of Radeon HD 5600/5500 series in the first generation DX11 family, with a maximum of 400 Stream Processor , 20 texture units, 2 rendering backend, 8 ROP unit , video memory Bit width 128-bit。 Unfortunately, independent GDDR5 There is no video memory, and it is not like 880G motherboard On board Hard video memory, can only share the system DDR3 memory 。

In addition to inheriting the original TeraScale 2 unified processing architecture, and the complete DX11 OpenGL 4.1 Various anti aliasing and Anisotropic filtering (including morphological anti aliasing MLAA), APP Parallel computing Beyond acceleration technology The Sumo core has also added the UVD3 video decoding engine and power gating (deep power management and energy saving) from the Radeon HD 6000 family, redesigned the video memory interface to the North Bridge, and synchronously adopted the latest GlobalFoundries 32nm in manufacturing technology.

The Sumo core is naturally a VLIW5 5D stream processor architecture, Single precision The floating point computing performance is up to 480GFlops, and the integer computing performance is up to 480Gints, both of which are 480 billion times per second.

Accelerate processor

As a Fusion APU competitor Although the HD Graphics 3000/2000 integrated by Intel Sandy Bridge has made great progress over the previous generation Graphic technology Video technology is still far behind. In particular, OpenCL parallel computing is only supported by the processor, and the graphics core does not support it, so it cannot be co accelerated.

Accelerate processor

The processor and graphics core of Llano APU support AMD APP accelerate Parallel processing technology , especially the OpenCL standard specification, for which AMD will constantly update the APP SDK Development package, providing better performance and more functions. According to the plan, APP SDK version 2.5 will be launched in August , mainly Windows 7/Linux performance optimization , Multi GPU support (Windows 7) fast fourier transform (Root cardinality 5), UVD3/MPEG2 decoding, PowerExpress exclusive display Collective display Switch support, GPU debugger (Windows 7) and so on.

It is worth mentioning that, The OpenCL specification version officially supported by Llano APU has been updated to 1.2 。

Chipset And energy conservation

Accelerate processor

along with Chip integration The composition of both desktop and mobile platforms is becoming more and more simple North South Bridge The dual three chip architecture has disappeared, replaced by the dual chip architecture of processors and interconnect chips. Most of the functions originally handled by Beiqiao have been transferred to the processor, including the graphics core, and the so-called chipset is left to serve as a South Bridge Functional microchip.

Accelerate processor

The Hudson series chipset matched with Llano APU processor is also Single chip Design, There are A70M and A60M models on the mobile platform , the codes are Hudson-M3 and Hudson-M2 respectively, through the UMI bus（ PCI-E 1.0 x4+DP) and processor interconnection. It is the same master brother as Hudson-M1 A50M, which was previously used for the Brazos APU platform.

A70M/A60M chipset adopts 65nm process manufacturing , 605 ball pin FC BGA package, chip size 23 × 23=529mm2, Typical thermal design power consumption 2.7-4.7W 。

Both chipsets support six SATA 6Gbps storage interface and support RAID 0 /1 array mode, can provide four PCI-E 2.0 x1 connection channels, integrated Clock generator 、 Consumer grade Infrared receiver , fan control, voltage sensing, DAC (support VGA ）Wait, the main difference is USB interface : The A70M natively supports four USB 3.0 , ten USB 2.0 And two internal USB 1.1, The A60M does not have USB 3.0, but 14 USB 2.0 。

There is also an optional replacement role on this platform, that is, the Vancouver Radeon HD 6000M series independent graphics card PCI -The E x16 channel is connected to the processor. It can not only bring unique display performance to the notebook, but also support the graphics core integrated with Llano APU to form a dual display switching and acceleration system.

Finally, let's talk about power management and Energy saving technology , including 32nm HKMG new process, AMD Turbo Core 2.0 dynamic speed regulation technology System management mode (SMM), ACIP compatible, P-states, C-states, S0/S3/S4/S5 Sleep state , each core power gating (CC6), PCI-E core power gating, Radeon stream processor core and UVD3 video engine power gating.

power gating (3 sheets)

Power Gating It is particularly worth mentioning. It is a very scarce technology in the AMD 45nm era, and now it is finally fully supported. Compared to Clock gating (Clock Gating), which can not only adjust the Operating frequency , voltage, and can be completely turned off when not needed to achieve partial zero power consumption. let me put it another way, Each processor core of Llano APU, each PCI-E controller, stream processor array, and UVD3 engine can be completely shut down The Turbo Core technology has also reached a new level.

All of the above belong to AMD AllDay all day computing technology. According to the data given by AMD, Ⅵ Standby time It can take up to six and a half hours, and it can take up to ten hours to welcome the VI Session 2011 of APU; At the same time, compared with competitors, standby Endurance More than one and a half hours longer, and the full load endurance will also be one hour longer.

Desktop level

Richland Platform

The dynamic frequency modulation technology on Richland APU is "Hybrid Boost", which integrates more Temperature sensor , and adjust the Turbo acceleration algorithm to make it more intelligent. In the past, CPU and GPU were accelerated at the same time when acceleration was needed, but this is rare. The current algorithm can ensure that those parts that need stronger performance will be accelerated.

Virgo Platform

The mobile platform is "Comal", and the new generation APU is manufactured by GlobalFoundries 32nm SOI HKMG process. It has 2-4 CPU cores based on the improved bulldozer architecture, and the core code is "Piledriver". It can be said that this part of the improvement is relatively large, because the CPU part of the previous generation Llano still uses the older K10 architecture, and the integrated GPU part has also been significantly improved, The HD6000 core will be replaced by a new graphics core with VLIW4 (the HD6900 of the Cayman core is the same architecture) architecture.

Trinity APU was officially released on May 15, 2012. Its main task is to replace Llano as a new generation of mainstream and high-performance mobile integrated processor. Like the Llano APU, it has at most four physical cores, but the core architecture has been upgraded from K10 to the Piledriver (the second generation of pile drivers Bulldozer ）The fusion single display part can have up to 384 DX 11 Radeons Stream Processor (upgraded to the VLIW 4 architecture of HD 6900 series), the matched single chip still supports SATA 6Gbps、 USB 3.0 、 PCI-E 2.0 and other specifications, as for dual display Hybrid CrossFireX The function is also continuously supported.

Compared with the previous generation of AMD APU, the new generation of pile driver core Trinity has made a leap in performance. Each of its computing modules is composed of two cores, each module is equipped with a 2MB cache. The pile driver provides IPC improvement Enhancements such as lease reduction, CAC reduction and frequency lift, which are different from Llano's design, make Trinity more powerful in performance, and the performance improvement will be very obvious. On the way to previously announced APU institutions, Memory controller Core unit throughput And information processing capability has always been an important improvement project. Because of integration, the improvement of these single functions will greatly improve the actual application performance of AMD Trinity.^[6]
