Due to time constraints, we didn't get a chance to fully examine the A750, but we will have something to say about that card by the end of this re-review. Naturally, we decided to look into all of this and in this article, we're revisiting the Arc A770 with an updated set of benchmarks, using the 4123 driver set. Rather than give actual performance figures, Intel used vague-looking graphs to indicate how much better the 4086 drivers were. There were some further claims of DX11 and DX12 performance improvements, but the actual gains were somewhat hidden behind a layer of marketing talk. By any measure, those are some mega increases – if true, of course. Lately, it made claims of big performance gains with the 4086 drivers, citing an average DirectX 9 performance improvement of 43%, with individual gains as high as 87%. With each new driver release, Intel continued to hone its software. This was eventually resolved by Intel removing native DX9 support and switching to an open-source mapping layer ( D3D9on12) that translated DX9 instructions into DX12 ones. Some DX12 games had multiple issues, and others just ran slow, but older titles using DX9 were catastrophically bad. It soon transpired that they had a serious Achilles' heel: drivers. And for the first games we tested the cards on, that was very much the case. When the Arc A770 and A750 graphics cards first launched, their specifications suggested that they would be more than a match for any model that AMD or Nvidia had in the same price category. Marketing claims and reality are often very different beasts, though, and there's only one way to see what's really going – benchmarks and a thorough analysis of the results. So far they have kept true to its word and there's been no shortage of new software, citing bug fixes and support for new games, but also lots of performance gains. Ever since Intel Arc GPUs launched, the processor giant promised to offer regular driver updates.
