nVidia’s CPU stacks up respectably against the AMD Threadripper 7980X

More eyes are nVidia’s GH200 Grace Superchip. The GH200 Superchip is the combination of a Grace CPU and a Hopper-based H200 GPU. While the results aren’t definitive, they should raise eyebrows.

In 39 individual Linux-based benchmark tests, Grace (the CPU side) beat the AMD Threadripper 7980X in 17 tests and the 7995WX in 15. It even stacks up well against Intel Sapphire Rapids.

Sapphire Rapids and Threadripper enjoy many advantages. Far more apps are optimized for x86 than for Arm. Threadripper has much more aggressive clock speeds than the efficiency-focused Grace chip and far more L3 cache (7980X has more than double, and the 7995WX more than triple).

But raw performance may not be the only consideration. There is speculation that Grace Hopper is more energy efficient – but there is no real data on TDP outside the whole package requirement of 500w. Also, for tasks that are more GPU bound than CPU bound, the combination may provide higher effective processing power than a faster CPU paired with a discrete GPU. Time will tell.

It shows that nVidia’s Grace entry is not to be ignored. Paired with the Hopper GPUs, it might offer a very viable alternative to x86 stacks – if your software can run on Arm.
