Second limitation is DX 9 - Intel won't be creating a DX 9 driver and instead there will be a translation layer that translates DX 9 system calls to DX 12. Resizable BAR can be enabled in the BIOS on supported platforms Without ReBAR the cards seem to lose some performance, in some games even a significant amount but more so the frame time consistency gets worse and you may notice stuttering or some random lag spikes. You will also need RTX 3000 or newer or Radeon RX 6000 or newer (or Intel Arc GPU).įor Intel ReBAR support is pretty much mandatory, to a point where Intel is advising not to buy and use their cards in systems without ReBAR support. ReBAR is available for Ryzen 5000 and newer (with BIOS updates it can be available for 3000 and newer), Intel 10th gen CPUs and newer. Enabling it does improve performance a bit, depending on the game, but it's not something big, more like a feature for future games to utilize. AMD calls it Smart Access Memory while Nvidia just sticks to the original name. This part of the spec wasn't used by PCs until recently. It's a part of PCIe specification and allows the CPU to access the whole memory of the GPU. First of them is Resizable BAR or ReBAR for short. There are some limitations Intel is facing. Gamers Nexus drivers adventure Technical limitations They have an enormous backlog of things to implement and fix that they are just overwhelmed at the moment.įor a detailed review of Arc A380 and Intel problems you can watch Gamers Nexus videos linked below: ▸ Intel is delaying the release because of their drivers and software. There are few laptops, some shops sell the A380 and other cards are constantly in release is coming soon mode. For laptops there are mobile variants and those are less known, although there are some A300M equipped laptops out there and initial benchmarks aren't that good.Īs of the time of writing this article Intel did not release Arc globally. For Ark generation, it's expected that A750/770 will have similar performance to RTX 3060 or RX 6600. Arc A550 will be middle of the pack and then Arc A750 and Arc A770 will be top SKUs. As for the numbers, they follow a similar scheme as their CPUs - Core i3 and A300 cards, i5 and A500 cards, i7 and A700 graphics cards.Īrc A380 is an entry level card and just like Core i3 will not win any benchmarks. Next generation is Battle Mage then Celestial and Druid. First generation is called Arc and all cards start with an A. Intel is planning to release multiple generations of their new dedicated graphics card. Some cards are already out so let's take a look at entry level Arc A380 and what Intel is planning to release. Intel is entering the discrete graphics card market with the Arc series.
