You could have learn my launch-day critiques of Intel’s Arc A750 and A770 graphics playing cards, the place I praised the potential of Intel’s {hardware}, but in addition famous numerous important points on the driving force aspect. Well, Intel has been arduous at work and is claiming some critical enhancements with its latest drivers, so it’s time to put that to the take a look at as we speak, the place we’ll even be analysing Acer’s Predator BiFrost A770 customized card.

In order to analyse the distinction made by Intel’s latest drivers, we examined each the A750 and A770 utilizing the 3491 driver from again in October, in addition to with the 4123 driver launched in February. This offers us two information factors per Arc GPU, so we are able to see precisely how issues have modified in the previous couple of months. Testing 12 video games in whole, we additionally embrace comparisons in opposition to the RX 6600 XT and RTX 3060.
Later on this article, we take a better have a look at the Acer Predator BiFrost A770 customized card and evaluate its efficiency, thermals and extra in opposition to Intel’s personal Limited Edition mannequin.
We’ve taken a have a look at the Xe HPG structure prior to now, however to remind ourselves of what we’re as we speak, above we are able to see a comparability of the core spec of the A750 and A770. Both SKUs are constructed on Intel’s ACM-G10 silicon, however the A750 is shaved down barely. The full die gives 32 Xe cores for the A770 nonetheless, the place every core gives 16 vector engines, with every vector engine housing 8 FP32 ALUs, for a grand whole of 4096.
Each Xe core is accompanied by a Ray Tracing Unit, whereas we additionally discover 224 TMUs and 112 ROPs. A 256-bit reminiscence interface is used for each A750 and A770, however 16Gbps GDDR6 reminiscence is used for the A750, giving whole reminiscence bandwidth of 512 GB/s. Intel additionally charges the A770 for 2100MHz graphics clock, and 225W whole board energy.
