- adrian_b 2y agoTheir speeds should be very similar, but which is faster is uncertain. There have not been any published benchmarks demonstrating the speed of Cortex-X925 in a laptop/mini-PC environment. In smartphones, Cortex-X925 and Snapdragon Elite have very similar speeds in single thread. For multithreaded applications, 10 big + 10 medium Arm cores should be somewhat faster than 12 Snapdragon Elite. The fact that NVIDIA Digits has a wider memory interface should give it even more advantages in some applications. The Blackwell GPU should have much better software support in graphics applications, not only in ML/AI, in comparison with the Qualcomm GPU. So NVIDIA Digits should be faster than a Qualcomm laptop, but unless one is interested in ML/AI applications the speed difference should not be worth the more than double price of NVIDIA.
- fweimer 2y agoIf the Nvidia system runs reasonably well with stock distribution kernels, it may well be worth the extra price. Usually, an optimized, custom kernel is a warning sign, but maybe they have upstreaming plans, and support for other distributions is planned.
- sliken 2y agoSure, but less than half the memory bandwidth and inference is largely bandwidth bound.
- kllrnohj 2y agoThe context was people that don't care about AI or Nvidia GPUs and just want an AArch64 system. So inference performance is irrelevant here > lots of people will buy these machines to get an AArch64 Linux workstation—even if they are not interested in AI or Nvidia GPUs.
- sliken 2y agoAh, sure the Oryon cores are decent, GPU is a bit weak, even compared to the normal cheap/low end APUs.
