These two stalks have been circulating for a long time, some players have been brainwashed, really believe that there is such a thing, especially the problem of negative optimization of N card, compared with the future of A card war, negative optimization can be said to be the negative of NVIDIA, although there have been so many tests that there is no negative optimization, NVIDIA officials also dispel rumors many times, but some people still believe it.
To this end, the Metech Web site has made a few more.AMDNVIDIA old card has been tested. On the side of A card are RX Vega 64 and Radeon VII, which were released only in February this year. It is not a real old card, but it is also the representative of GCN architecture.
NVIDIA here are GTX 1080, GTX 1080 Ti and RTX 2080, but RTX 2080 used a public card last year, this time using a non-public version of Gigabyte RTX 2080 Xtreme, the original said that the impact on performance is only 1-2%, so the gap is not enough to reverse the results.
In terms of driver, N card uses GeForce 411.63 driver last year, the latest version is 430.86, and the old version of A card is Adrenaline 19.5.2. They did not mention the specific version number of the latest driver of A card.
In addition, on the system side, last year's test was inWindows10 1803, this year's driver is Windows 10 1903, and fuses, ghost vulnerabilities and related patches are the default status.
The games tested included Ashes of the Singularity: Escalation, Deus Ex: Mankind Divided, Hitman, Metro Last Light Redux, Middle Earth: Shadow of War, Rise of the Tomb Raider, Warhammer II, Shadow of the Tomb Raider, Assassin's Creed: Origins and Far Cry 5.
It should be noted that Ashes of the Singularity: Escalation and Warhammer II have suffered a decline in performance, and AMD and NVIDIA graphics cards are the same, but other games do not have such a situation, so they judged that the performance of the two games declined due to the repair of ghost vulnerabilities, and neither did the performance of the two games. Enough to distort all test results.
The final test results, they give a comprehensive result, based on the resolution, the lowest frame rather than the average frame, the higher the result, the better.
Having said so much, the final result is that the performance of Radeon VII in AMD graphics cards remains unchanged, and the frame number of Vega 64 has increased from 32 to 36 fps, which is more or less valid in the future.
Among NVIDIA graphics cards, the final performance of three types of graphics cards is also improved. RTX 2080 has been upgraded from 42fps to 47fps, GTX 1080 has been upgraded from 38fps to 40fps, GTX 1080 Ti has been upgraded from 41fps to 45fps.
Even taking into account the differences in the above card models, conservatively speaking, even if the N card has no future, negative optimization is obviously untenable.
