>Single-socket submissions show that AMD's 128-core, 256-thread Epyc 9754 scores right around 922 in the benchmark, about 2.58x higher than Ampere's top-specced Altra, the M128-30, which comes in at 356.
>While a clear win for AMD's Bergamo, it doesn't take into consideration other elements like power consumption. AMD's part is rated for 360W and can be configured up to 400W, while Ampere's has a TDP of just 182W. So yes, it may be 2.5x times faster, but it potentially uses 2-2.2x more power.
that's still a major win for AMD. 2x performance per core means you need half as many servers (which is way cheaper) and all your latency bound operations happen twice as quickly. (also I'm pretty sure you can underclock the AMD system to the point where it's the same power and 50% more performance)

Public cloud providers will sell you that amount of compute for about $50-$100 per day.
The lower end of that is the Ampere processor and the high end would be the AMD 128-core processor.
In other words, they can make $49 more by using the AMD CPU per day.
