RX 580 can win, RTX 3080 graphics card big V says NV driver dx12 is not optimized enough

For video card players, a card battle in the future and N card negative optimization are very magical. Now it may give players another chance, because it is revealed that the driver is not optimized enough for dx12, and the performance of RTX 3080 is even inferior to that of Rx 580.

Big hardware on YT V@Hardware Unboxed recently paid attention to the optimization of NVIDIA driver for the old CPU, and did a lot of tests. It was found that when the RTX 3080 graphics card was used with the old and low-end CPU, the performance of dx12 declined seriously.

He has tested a number of games, including "watchdog: Legion", "Tomb Raider: Shadow", "Horizon: Dawn", "death stranded", "Rainbow 6: Siege", "cyberpunk 2077" and "Assassin's Creed: the hall of the souls" (screenshots below).

What he found out was that,Under dx12, when the RTX 3080 graphics card is equipped with core i5-9400f, sharp dragon 51400 and other processors, there will be performance problems. The number of game frames is even less than that of the RX 5600 XT graphics card,The domestic price of the latter is 2099 yuan (recommended price), and the performance gap between them should be very large.

It's not only inferior to the RX 5600 XT, but if the CPU is old enough, such as with the core i7-4790k flagship,The performance of RTX 3080 is even worse than that of Rx 580.


It's no surprise that high-end graphics cards like RTX 3080 eat CPU,In the test of hardware unboxed, the CPU like the sharp dragon 55600x can play its function normally.

But don't worry about hardware unboxed. It's a bit strange, because the performance of AMD and NVIDIA graphics cards under Dx11 and Vulkan is very normal.

Whether this is a driver bug or a normal phenomenon depends on NVIDIA's response. Judging from the current situation, when high-end graphics cards such as RTX 3080 are used with old models or low-end CPUs, there are still some problems in dx12 performance, which haunts n-fan's embarrassing negative optimization.
