ARM Linux Server Performance Up More Than 7x Geo Mean In 8 Years, As Much As 15x With NVIDIA Vera CPU
The Stream memory benchmark was pretty wild and fun to see. Going from eight channel DDR4-2400 memory to LPDDR5X-9600 memory with NVIDIA Vera yielded around an 11x improvement.
For those curious how far ARM server CPU performance has evolved in less than one decade, now you have some numbers to quantify the ARM hardware performance from the original Ampere eMAG to the new NVIDIA Vera.
The geo mean of 7.04x improvement from Ampere eMAG to NVIDIA Vera is in fact rather conservative with the many single/lightly-threaded workloads run and also not being as many benchmarks as I typically run for diverse workload coverage, due to being limited in the benchmarks that could be run when originally testing Vera and the time constraints. But even so 7x faster over the past eight years is an impressive feat on its own. In the most extreme cases like 7-Zip was a nearly 15x improvement going from Ampere eMAG to NVIDIA Vera.
There is the TDP increase too with the Ampere eMAG being at 125 Watts compared to NVIDIA Vera at around 500 Watts but that is both for the 88 CPU cores and the LPDDR5X memory. With Ampere eMAG the eight DDR4 RDIMMs will add to the TDP as well, but even with rough calculations, the performance-per-Watt has significantly improved too over this period.
The ARM Linux performance evolution is also more staggering if factoring in the countless software optimizations over this same time period too. But long story short, the ARM Linux CPU performance has come a long way in the past eight years.
