Sapphire RX 7900 GRE polar version, with a direct drop of 800 yuan, and a performance jump of 10%

RX 7900 GRE Yes AMD A medium and high-end model launched in July 2023 Graphics card , we have evaluated many products of this series before. Today, we bring you the evaluation of the Sapphire RX 7900 GRE 16G D6 polar OC.

Before the evaluation, let's talk about the price. This RX 7900 GRE When it was just released, AMD's official recommended price was 5299 yuan. At present, this sapphire RX 7900 GRE 16G D6 polar version OC The official price will be reduced to only 4499 yuan.

It is not difficult to find that NVIDIA just released the RTX For the 40 SUPER series, the main thing is to increase the quantity without increasing the price. The performance of the RTX 4070 SUPER card is exactly the same as that of the RX 7900 GRE. The official recommended price is 4899 yuan (although most AICs are above 5000 yuan at present), which has a great impact on the RX 7900 GRE of 5299 yuan.

Now the RX 7900 GRE has a direct drop of 700 yuan, 400 yuan cheaper than the RTX 4070 SUPER, and the performance is a little bit better. It can only be said that competition is better for consumers. (The price fluctuates, subject to the real-time price of e-commerce)

Now let's take a look at the appearance of this sapphire RX 7900 GRE 16G D6 polar OC.

one Sapphire RX 7900 GRE 16G D6 Polar OC Overview

The packaging of the Sapphire RX 7900 GRE 16G D6 polar OC is mainly pure white, with some blue embellishments. It is not as clean as other designs with strong quadratic or e-sports style.

Sapphire RX 7900 GRE 16G D6 Polar Edition OC can be seen from the shape of the chamfer on the left side that it is designed with the platinum version as the base, but there is a big difference in the drawing of the shroud. The polar version uses classic black and white color matching, plus some dark lines, which makes the whole quite harmonious and simple.

The size of this video card is 320 × 129 × 53mm, and the size is relatively large. However, due to the elegant overall color matching, it still looks exquisite, without the feeling of bulkiness.

Sapphire RX 7900 GRE 16G D6 polar version OC uses three 9-blade flying wing axial fans, which can provide greater wind pressure and air volume, and lower noise, At the same time, the double ball structure can also extend the service life of the fan.

Sapphire RX 7900 GRE 16G D6 polar OC uses a full-size integrated metal backplane, in addition to hollow heat dissipation and decoration. The new polar series graphics card has changed the original dark gray platinum version of the "heartbeat curve" to "PURE", meaning pure, pure, pure, etc.

In terms of internal heat dissipation, the Sapphire RX 7900 GRE 16G D6 polar OC uses five nickel plated heat pipes and thickened fins. The heat pipes running through the head and tail can quickly and evenly distribute heat to the whole heat dissipation module.

High density multi fold copper PCB board can improve the signal transmission speed and signal stability of the graphics card, with high durability, and ensure the performance and stability of the graphics card in long-term operation.

The whole card thickness of Sapphire RX 7900 GRE 16G D6 polar OC is 2.5 slots, The video output interface adopts the design of HDMI 2.1 * 2+DP 2.1 * 2.

The latest DP 2.1 interface has a transmission bandwidth of 54Gbps, supports the display of 12bit color depth and 68 billion colors. At the same time, it can support 4K/480Hz and 8K/165Hz ultra-high definition and high brush image display.

The side of the Sapphire RX 7900 GRE 16G D6 polar version OC is quite different from that of the previous polar version. The new "SAPPHIRE" logo is located in the middle, and red light is emitted after the operation.

On the power supply interface, the Sapphire RX 7900 GRE 16G D6 polar OC still uses a dual 8pin interface, which is very friendly. The power consumption of the whole card is about 265W, and the recommended power supply is 700W.

two Introduction to test platform

For this test platform, we chose Intel's previous generation flagship processor, and the motherboard is MSI MEG Z790 ACE Ares. (All test data this time are obtained after SAM is started)

Before the test, let's take a look at the parameters of RX 7900 GRE for comparison and reference. Here is a brief summary:

The above comparison is the official parameters of AMD, excluding OC overclocking versions. It is easy to see from the parameters that the acceleration frequency of RTX 7900 GRE is relatively low among the three graphics cards, but the grating/texture unit and computing unit are much higher than RX 7800 XT.

In addition, it should be noted that in terms of video memory bandwidth, the brackets are the final effective bandwidth after Infinity Cache amplification.

In terms of specifications, the Sapphire RX 7900 GRE 16G D6 polar OC has 5376 stream processors and 16GB GDDR6 video memory. The video memory bit width is 256 bits and the bandwidth is 576 GB/s. The grating/texture unit is incorrectly identified here. In terms of frequency, this polar OC is 2333MHz , the public version is 2245MHz , slightly improved.

three Theoretical performance test

The first step is to measure the graphics card DX11 The 3DMRKFS package with theoretical performance: FS, FSE and FSU correspond to the theoretical performance of the graphics card at 1080P, 2K and 4K respectively. The actual test results of the graphics card scores are as follows:

In this test, we choose RTX 4070 SUPER and Sapphire RX 7900 GRE 16G D6 polar OC for comparison.

In the 3DMRKFS package test for the performance of the graphics card DX11, compared with the RTX 4070 SUPER, the Sapphire RX 7900 GRE 16G D6 polar OC has been improved by FS 0%/FSE 9%/FSU 13%， Comprehensive increase of 7% 。

In the Time Spy and Time Spy Extreme tests for the DX12 environment, the difference between the Sapphire RX 7900 GRE 16G D6 polar OC and the RTX 4070 SUPER is TS 4%/TSE 3%。

PortRoyal is 3DMARK The test item of the secondary specialized school for light pursuit performance, Sapphire RX 7900 GRE 16G D6 polar version OC compared with RTX 4070 SUPER The gap is 8% 。

Speed Way test is the latest update of 3DMARK to test the performance of DirectX12 Ultimate graphics card benchmark. This test combines real-time ray tracing and traditional rendering technology to measure the performance of the graphics card. The scene contains raytraced reflections, real-time global lighting, mesh shaders, volume illumination, particles, and post-processing effects.

The difference between the sapphire RX 7900 GRE 16G D6 polar OC and the RTX 4070 SUPER in 1080p resolution is about 19%, and the difference in 2K resolution is 17%; The 4K resolution is 12%. With the advantage of 16GB large video memory, the gap is gradually narrowing.

In the FSR test of 3DMARK, the performance improvement of Sapphire RX 7900 GRE 16G D6 polar OC in three resolutions is 58%/72%/86% 。 The higher the resolution, the more obvious the improvement effect will be when FSR is turned on, and the better the image quality will be maintained.

To sum up, this retest of the Sapphire RX 7900 GRE 16G D6 polar OC has significantly improved the performance of DX12, PR and SW. Compared with the first release, the performance has improved by about 10%!

You can also look at the previous evaluation records. Last time we tested the RX 7900 GRE Super Platinum OC. Although the performance was stronger than that of the RTX 4070, there was still a big gap in benchmarking today's RTX 4070 SUPER. This time we retested this card, which is not as well positioned as Super Platinum, but it was still slightly better. It can be seen that AMD drive The importance of optimization, let's take a look at the actual measurement of the game.

four Game performance test

In game testing, as A/N involves optimization by different companies, the performance is not as accurate as the theoretical score of 3DMARK. However, we also tested several popular 3A games for everyone.

In Extreme Racing: Horizon 5, Sapphire RX 7900 GRE 16G D6 Polar OC Compared with the performance of RTX 4070 SUPER, it has been improved to 2%/3%/3% 。

On《 Assassin's Creed 》In the series of tests, this time we upgraded to the latest Assassin's Creed: Mirage, The performance of Sapphire RX 7900 GRE 16G D6 polar OC is improved to 2%/6%/9% compared with RTX 4070 SUPER 。

In Land Without a Master 3, Sapphire RX 7900 GRE 16G D6 Polar OC Compared with RTX 4070 SUPER, it is increased by 7%/15%/15%.

After the game is retested, the frame number increases most obviously. The previous three resolution frame number is 155/116/64. And in The Land Without a Master 3 benchmark The settings are very simple. As an old game, it has not been updated, so the scores are relatively authentic and reliable.

The test items in Cyberpunk 2077 are divided into "Super" and "Ray Tracing: Super". （ AMD graphics card The FSR quality mode NVIDIA graphics card DLSS quality mode is enabled for all tests)

First, let's look at the achievements of Wuguang Chasing, Sapphire RX 7900 GRE 16G D6 Polar OC The leading range is still relatively large, averaging about 15%.

In the ray tracing super presets, NVIDIA has obvious advantages. Although it also has the blessing of FSR, the ray tracing game is indeed NVIDIA's home advantage.

five FSR test

In the FSR test, we chose Star Sky from Agency B, which comes with FSR 3.0. However, no specific gear is given in the game, and the test will be manually adjusted according to the zoom ratio of different gears. In addition, the zoom below 50% cannot be adjusted in the game, so there is no super performance gear.

The FSR 3.0 of Starry Sky currently supports the frame generation function, so we all test at 4K resolution to see how much the final improvement is. At the same time, compare the image quality of different gears and options.

It is explained here that "4K FSR3 frame generation is on (100%)" in the above figure. Since there is no direct gear setting in Starry Sky, but you need to manually adjust the zoom, the above setting is [FSR zoom is not enabled, but the frame generation function is enabled].

In terms of image quality (the contrast image is 2K resolution, which can be compared by manually loading a large image), the overall gap between FSR and the performance gear is not big. You can pay attention to the stone columns under the street lights. The main difference is the outline of the corners and the shadow details.

In addition, the author found that there was no difference before and after comparing the frame generation switch, but the frame number increased significantly. Interested players can download Look at the pictures and compare them.

six Temperature and power consumption test

In the power consumption and temperature test, we choose FurMark Software Carry out copying test and use GPU-Z Temperature detection and power consumption only calculate the graphics card itself.

GPUZ does not fully support card A, Sapphire RX 7900 GRE 16G D6 Polar OC When the graphics card is fully loaded, the temperature of the toaster is about 66 ℃, the hot spot temperature is 80 ℃, and the fan speed is 31%.

In addition, FurMark also supports power consumption monitoring for A card. It can be seen that the real-time onboard power consumption is 265W.

seven Direct drop of 800 yuan, performance soared by 10%

The last time we evaluated the RX 7900 XT, it was mentioned that the price was reduced. This time, the price of the RX 7900 GRE was also increased. 800 yuan is still a large proportion for a high-end graphics card.

And judging from the evaluation results, after more than a year, AMD did not wait in place, and after several iterations, the driver has already shown quite good performance. Compared with the first test, the performance has improved significantly.

In this way, compared with the three NVIDIA RTX 40 SUPER cards, AMD also has similarities and differences. Although no new products have been released, the price reduction and performance increase are also benefits for players in the competition between the two sides.

In terms of games, most 3A games have very high performance requirements, Sapphire RX 7900 GRE 16G D6 Polar OC At 2K resolution, it can basically achieve a frame rate of more than 100 frames. Even at 4K resolution, it can run smoothly.

Compared with RTX 4070 SUPER, although the official suggested price is 4899 yuan, the current market price of even the Beggar version is about 5099 yuan, and the OC version is even more than 6000 yuan. On the other hand, the RX 7000 series is a real price reduction, full of cost performance, and back to the familiar AMD.

This evaluation Sapphire RX 7900 GRE 16G D6 Polar OC Compared with the previous XT model, the red "SAPPHIRE" logo light is added on the side. Although it is "dazzling", it is not inconsistent with peace, just like the winter sunshine in the snow, full of warmth.

At present, this Sapphire RX 7900 GRE 16G D6 Polar OC sells for 4499 yuan in the flagship store. Interested users can go to the e-commerce page to learn more.
