You will be amazed at the performance difference between DX 11 and DX 12
Intel is slowly revealing its Arc Alchemist graphics cards. After showing the A770 reference model, It’s time to look at what a high-end SKU can do. A new video from the Linus Tech Tips channel demonstrates just that GPU is much better in DirectX 12 And talks about optimization levels in terms of drivers and more.
Linus used two identical systems, equipped with a Core i9-12900KS, 32GB DDR5-4800 and Arc A770 GPUEach runs the same game on a different API, DX 11 and DX 12. The result is quite interesting and shows how much work is still to be done with Intel’s video drivers.
In Shadow of the Tomb Raider, performance doubles from DX11 to DX12 and leaves From 39 FPS to 80 FPS. This is because Intel has prioritized optimizing the DX12 API in their video driver. Although many games use this API today, as Linus himself points out, the most played ones on Steam are DX 9 and DX 11.
Intel explains how to optimize drivers
Intel’s Tom Peterson explains that the company has a so-called “three-tier” strategy for optimizing its drivers for specific games. He says the first group is “going to screw everyone over on price/performance.” That is, they will get the best performance in this group at the lowest price.

The games that belong to this group are 1 Popular titles that use DX 12, such as Cyberpunk 2077, Control, Fortnite and F1 2021. The A770 ran the latter at 1440p above 150 FPS, reaching 199 FPS. Only Shadow of the Tomb Raider and the racing game had performance metrics revealed. Linus says he felt like Cyberpunk 2077 was running at around 60 FPS and set to a high 1440p.
Intel Arc graphics cards will compete with GeForce RTX 3060 Ti and Radeon RX 6650 XT.
The second group refers to less optimized games that use DirectX 12 and Vulkan APIs. The third group, as you can imagine, is talking about games made in DX 11 or older versions, where the drivers are not optimized at all.
Linus says Intel will charge its cards based on Tier 3, or lower performance. This means that even the Arc A770, the top-end GPU, should be cheaper than its direct competitors, which are cards according to the leak. NVIDIA GeForce RTX 3060 Ti and AMD Radeon RX 6650 XTPlates under $400.

As the video closes, Linus vaporizes the A770 again. It boosts the GPU clock to 2500 MHz with a power coverage of 190 W. But Intel’s software is, in Tom Peterson’s words, “buggy” and doesn’t show data correctly, like GPU usage at 4%. When I overclock a bit more, I get to 285W, the game and program freezes and closes.
Even after all this, Intel still hasn’t provided details on the high-end Arc A770 GPU configurations, availability and pricing. We will have to wait a long time. At least we know they exist.
