6500XT is so rubbish. Why do players still buy it?

AMD RX 6500 XT Graphics card It was released on January 19, and the author didn't feel anything wrong when writing the evaluation. It was just a conventional performance reduction. And according to the sale, this video card does not have much premium, it is a video card that can be bought by players.

But at present, the voice on the Internet is polarized, support The RX 6500 XT camp said, "This is really a brand new cost-effective graphics card that can be bought within 2000 yuan"; con side The camp believes that "this specification is not worth 1000 yuan, and it is recommended to use an office computer+host (Xbox PS5 ）Transition ".

On this matter, other colleagues in the department also asked me, is this video card really garbage? I nodded silently, really rubbish. However, as a person who is involved in the hardware circle, he gave an example:

"It is equivalent to that the mine owner and scalpers bought the bread and pizza, and then AMD made some steamed buns for the players?

Yes, and it can only be steamed buns. Even if some soy bean curd is put on the steamed buns, they will be robbed.

What about Old Huang, who didn't even make a steamed bun?

Old Huang is trying. Now it's two steamed buns with soy bean curd, but they are still robbed. It's estimated that the next step is a steamed bun. "

01 How big is the impact of 4GB video memory

So what is the existence of the RX 6500 XT released by AMD this time? Is it really equivalent to a steamed bun? Now let's look at what has been reduced.

First, we compare the parameters of the RX 6500 XT released this time with those of several other corresponding graphics cards, and pay attention to the video memory related parts marked yellow.

This time, the most critical thing is that the RX 6500 XT video memory has been greatly reduced, with a 4GB capacity of 64bit bit width, equivalent to 114 GB/s. However, according to the official statement of AMD, with the addition of 16MB Infinity Cache bandwidth amplifier, the final effective bandwidth can reach 232 GB/s， Basic and RTX The 3050 is the same as the RX 6600, but the video memory capacity remains the same.

Extreme image quality requires 7.2GB video memory (click the picture to view the large picture)

High picture quality (click the picture to view the large picture)

In the test of Horizon 5, the extreme image quality even requires 7.2GB of video memory, which is catastrophic for the RX 6500 XT and can be reflected in the number of frames. After being adjusted to high image quality, although it still exceeds the available video memory, the frame number can reach the smooth standard.

Although the change of preset image quality will also affect the quality of maps, shadows, etc., the increase or decrease of the quality of these options is ultimately reflected in the demand for video memory.

After our test, the frame number of burst video memory and non burst video memory is different day by day under the same 1080P resolution. At the same time, most 3A games, even at 1080P resolution, have a preset maximum image quality that exceeds the 4GB memory capacity requirement.

02 PCIe 4.0 × 4 channel means worse

The other is the castration of PCIe channels. The interface channel of RX 6500 XT is only PCIe 4.0 × 4, while the previous RX 6600/6600 XT is PCIe 4.0 × 8, and that of RX 6700 XT and above is PCIe 4.0 × 16.

In fact, for the bandwidth of the PCIe interface, some graphics cards are not useful, while others are very important. The actual meaning of the PCIe interface bandwidth for graphics cards is to exchange data.

For RTX 3090, the large 24GB video memory makes it impossible for any game to run full. There is no possibility of video memory explosion. Therefore, the PCIe interface bandwidth has little impact on such video cards.

The RX 6500 XT has only 4GB video memory, which may explode even at 1080P resolution. At this time, if the video memory cannot be stored, only the PCIe channel can read the temporary data in the memory.

From the above test, the difference between the two frame rates in 3A games that exceed 4GB video memory requirements is large. And such as《 fortress Night: For online games with lower video storage requirements, there is little difference.

However, the new online game Rainbow 6: Heterogeneous is an example. As the 4GB video memory of RX 6500 XT cannot meet the test under the highest image quality, it can only reduce the image quality by one file, reducing the video memory of the game to about 4GB.

So, the PCIe interface speed is Video card easy to explode The impact is the biggest, but it has little impact on the large video memory card.

03 Castration of video encoding/decoding

Another reduction of RX 6500 XT that may not be paid much attention to is the castration of video encoding/decoding. Specifically, H265/HEVC encoding is not supported, and AV1 decoding is not supported.

H265 coding is of little significance to ordinary users. It is mainly used for video production, but in today's era when everyone is We Media, it is better to have something than nothing.

Users who use Apple phones should know that there are two modes in camera settings: efficient mode and compatibility mode. The video captured in efficient mode is not normally exported to the computer and cannot be edited directly. This is because Apple's efficient mode uses H265 encoding.

Comparison of H.264 and H.265 encoded video at the same bit rate

The H265 code has a higher compress Ratio. Under the same picture quality, the bit rate is 50% less than H264. In other words, it is smaller at the same bit rate, and its definition is higher than that of H264 in terms of picture details, especially in terms of facial details.

The H265 encoding of RX 6500 XT castration finally causes that the graphics card cannot participate in rendering when the video is exported. However, you don't need to worry about daily play. You can watch the play without any problem.

AV1 decoding is the function of NVIDIA RTX 30 series and AMD RX 6000 series video cards, which is also related to video capabilities.

In fact, whether the graphics card has this ability or not, it will not affect us to watch AV1 encoded videos. The difference is hard solution and soft solution. In short, the video card is soldered with a decoder To view the AV1 encoded video, you only need to use the decoder to complete the hard decoding of the video.

Station B supports AV1 encoding Video playback

For graphics cards without hard decoding capability Software Decoding, that is, CPU soft decoding. The result of this is that the occupancy rate is very high, which will cause the computer to get stuck, consume very large performance resources, and heat and power consumption will also increase.

Although it has various advantages, the current AV1 encoded video is not mainstream. Even if it is the trend of the times, the big market of AV1 coding will be 2-3 years later.

04 Optimal solution of brand new video card within 2000 yuan

After talking about the shortcomings, let's see why the players buy it.

In terms of performance, the RX 6500 XT is slightly inferior to the GTX 1660 SUPER, and is equivalent to the previous generation of AMD's RX 5500 XT. For those who play online games and play 3A occasionally, this function is adequate.

At present, the new RX 5500 XT claimed by various stores sells for about 3200 yuan, and the GTX 1660 SUPER also sells for about 3200 yuan.

GTX 1660 SUPER market price above 3299 yuan

It can be said that RX 6500 XT is the only option on the market that can buy brand new products within 2000 yuan. On the NVIDIA side, the price of RTX 3050 1899 yuan is indeed less than 2000 yuan, but the after-sales price has soared to more than 2800 yuan, with a premium of 1000 yuan.

Returning to the metaphor at the beginning of the article, 8GB video storage is like two steamed buns with soy bean curd, which were snatched away by scalpers and mine owners every minute. If you want no premium or less premium, the best way is to cut down the stock price. The scalpers don't like it. The mine owner thinks it is worthless, so no one will fry it.

The current market price of RTX 3050 is 2899 yuan

Of course, the last thing left for players is a steamed bun that can barely fill their stomachs. This generation of players is really miserable. We are just a bad player and don't deserve a good video card.

Different voices believe that you can buy a game book, or a combination of a game console and an office computer. However, the game is limited by power consumption, and the mobile video card is not as good as the desktop level performance of the same model; Secondly, the heat dissipation of the game book has always been a problem that is difficult to solve. It's OK in winter, but it can basically be used as a stove in summer.

If you are a heavy game enthusiast, you may also need a separate monitor. The overall price is not cheap. When it comes to portability, game books should not be considered.

The laptop with RTX 3050 costs 5800 yuan

Another combination of game consoles and office computers is just another wishful transition method: "I have a good video card to use anyway, and I'll tell you this method. If you want to use it, you can become a big enemy without using it".

For users who want to save their computers, since they have the intention to do so, most of them will not find another way out. It's like going from home to the company. Although it's only two kilometers away, I want to buy an electric car to commute and ask which one is better. You said walking to exercise

Sapphire RX6500XT 4G Platinum Edition

To sum up, the RX 6500 XT video card is really garbage in specifications. Compared with other RX 6000 series products, it is not even like this generation of products.

On the other hand, RX 6500 XT is also the only video card that can be bought by players at a low premium. Funny, sad.
