![]() ![]() I then rebooted, disabled ReBAR on the BIOS level, and played the same Cyberpunk segment again. (This test's "1 percent low" frame rate count, indicating the worst persistent dips, measured above 30 fps, which is pretty good.) With ReBAR enabled on my AMD Ryzen 7 5800X system, I could expect smooth-enough driving at 1440p with "high" settings enabled and ray tracing disabled. The best example I found was in driving along Cyberpunk 2077's sprawling highways at high speeds. ![]() Intel's Arc architecture leans heavily into ReBAR's wide-open pipeline to your GPU's frame buffer-so much so that it doesn't have a fallback when a game's workload includes constant streaming of assets like textures. ![]() Will the Arc A750 and Arc A770 graphics cards work without Resizable BAR enabled? Yes, but we don't recommend it. The shortest explanation is that a ReBAR-compatible motherboard can send much larger chunks of data to and from the graphics card on a regular basis, and Intel would really like you to turn the feature on if possible. We say "and/or" because they're branded versions of the same technology. Intel strongly urges buyers of its new Arc graphics card line to triple-check their computer’s support for a pair of relatively recent features: Resizable BAR ("ReBAR") and/or Smart Access Memory. While none of our testing results were necessarily revolting, a significant percentage tasted funny enough to make a general recommendation pretty tricky. Yet our time with both Arc-branded GPUs has been like picking through a box of unlabeled chocolates. The best results are trained on modern and future rendering APIs, and in those gaming scenarios, their power and performance exceed their price points. In great news, Intel is taking the GPU market seriously with how its Arc A770 (starting at $329) and Arc A750 (starting at $289) cards are architected. While this is a fantastic first-generation stab at an established market, it’s still a first-generation stab. Without firm answers from Intel on how many units it's making, we’re left wondering what kind of Arc GPU sell-outs to expect until further notice.) (Sadly, limited stock remains a concern in modern GPU reviews. If those factors continue to move in consumer-friendly directions, it will mean that people might actually get to buy and enjoy the best parts of Intel’s new A700-series graphics cards. Intel now has a series of GPUs entering the PC gaming market just in time for a few major industry trends to play out: some easing in the supply chain, some crashes in cryptocurrency markets, and more GPUs being sold near their originally announced MSRPs. That last question is easy to answer: yes, and pretty well. Further Reading Rumors, delays, and early testing suggest Intel’s Arc GPUs are on shaky ground ![]()
