The guys at Computerbase.de introduced more comparisons than interesting and we will emphasize it until we release our comparison data based on various Navi models. To do this, they have selected three Navi graphics cards that perform different functions and ranges: RX 5500 XT (4 and 8 GB), RX 5600 XT and RX 5700.
All cards are tested under both sides to see if the exchange and distribution are appropriate for the new AMD Zen 2, X570 and Navi. Featured by Ryzen 7 3700X, X570 Godingly and 16 GB with Samsung B-Die at 3200 MHz 14-14-14-32 as well as the latest drivers available in all cases, check out more games at 1920 x 1080, Will PCIe 4.0 succeed in comparing to PCIe 3.0?
The bus is not as important as building a fabric / VRAM ratio
Considering that we are seeing percentages and that the lowest drawings have been uploaded to analyze the frames, we can see that the difference is still, between 1%, where in addition the RX 5600 XT achieves better results compared to the RX 5700 8 GB.
But when you extend the composition you are fully informed of how the Fram times start to be different. The only GPUs that are unaffected are the RX 5700 8 GB and RX 5500 XT 8 GB, where the logical parallel is VRAM value.
This shows that the import and export is done per second due to the low VRAM capacity, high speed PCIe 4.0 is essential to improve Frametime, and this should encourage performance.
With regard to FPS, for low-quality drawings loaded with error difference, less than 1% in total, so that in its times, performance is the same.
But when we go to upload high performance games the difference comes back up, this time in FPS. The situation is repeated, where two 8 GB cards are unchanged in terms of performance vs bus, but in the RX 5500 XT 4 GB and RX 5600 XT 6 GB things are different.
In the first case, for the RX 5500 XT bus version it means 6% more FPS and even then, it will lose another 5% compared to the 8 GB version, something we have already seen in our review and comparison of the RX 5500 XT compatible for both cards.
The RX 5600 XT 6 GB also suffers, but to a lesser degree. 5% is the distance between different buses, indicating that its VRAM is not sufficient for this decision and implementation.
Conclusion PCIe 3.0 vs PCIe 4.0
Choosing the right graphics card model is also important in these times. Games are getting worse RAMCaché due to not being able to get enough space in VRAMs and for that reason they are loading a very high amount of information and processing into system RAM.
Therefore, PCIe becomes more important for each update of the engines and games it supports, RAM usage is triggered and VRAMs are completed. Or RX 5500 XT they are physically limited to PCIe 4.0 X8 and yet we see 11% more performance between their two memory variants.
In the case of the RX 5600 XT, its lack of a large VRAM option makes it clear that PCIe 4.0 has some high performance with everything in mind, which makes that version reasonable for this card, but at the same time we consider the option to buy an RX 5700 with a cheap motherboard out PCIe 4.0 support.
Therefore, the bus is not very important but the price of VRAM found on the card, because it allows less access to system RAM for lower bus usage itself, and thus, the conflict between PCIe 4.0 vs. PCIe 3.0 would be specified (in part) by a small amount of VRAM on our card.
We'll have to learn if it doesn't make it more preferable to choose a PCIe 3.0 motherboard with a higher GPU or more VRAM before installing the new PCIe 3.0.
