Arc A770 and A750 graphics cards, ReBAR activation is necessary – GinjFo

In an interview with PC Games Hardware and Digital Foundry, Intel’s Tom Petersen confirmed the official launch of the Arc A770 and A750 gaming graphics cards. We are talking about models for our desktop computers.

The performance of the “flagship” Arc A770 GPU will be at the level of the GeForce RTX 3060 and 3060 Ti. The card will also be faster than the Radeon RX 6600XT. On the issue of Ray Tracing, the services will be similar to those offered by Nvidia’s Ampere architecture. In the end, and despite several rumors announcing it, the Arc A770 will not be a competitor to the GeForce RTX 3070.

Note that if performance improvements are made before D-Day, they will remain minimal. Tom Petersen pointed out that these Arc A-Series solutions “ can’t really change drastically on performances”.

The Arc A770 is capable of accommodating 8 GB and 16 GB of video memory. The “Limited Edition” variant is only available in 16 GB. The Arc A750 will be accompanied by 8 GB of VRAM.

Intel is working on graphics drivers targeting configurations that do not support ReBAR technology. However, this environment is not mastered to the point that Intel advises to stick to the competition for the moment. Clearly, if your PC does not support ReBAR, it is better to rely on a Radeon RX or a GeForce RTX.

Intel Arc GPUs are optimized for large copy operations (burst transactions) and not small transactions. As a result, they lose nearly 40% performance when used without ReBAR technology.

Finally the Arc A770 and A750 Limited Edition (Intel reference design) will be available on Intel’s website at launch. The company plans like Nvidia to launch its design alongside custom cards from its partners.
