alt Hacker NewsPhoronix recently reviewed the 196 core Turin Dense against the AmpereOne 192 core.
* Ampere MSRP $5.5K vs $15K for the EPYC.
* Turin 196 had 1.6x better performance
* Ampere had 1.2x better energy consumption
In terms of actual $/perf, Ampere 192 core is 1.7x better than Turin Dense 196 core based on Phoronix's review.
So for $5.5k, you can either buy an AmpereOne 192 core CPU (274w) or a Turin Dense 48 core CPU (300w).
Ampere has a 256 core, 3nm, 12 memory channel shipping next year that is likely to better challenge Turin Dense and Sierra Forest in terms of raw performance. For now, their value proposition is $/perf.
Anyway, I'm very interested in how Qualcomm's Nuvia-based server chips will perform. Also, if ARM's client core improvements are any indication, I will be very interested in how in-house chips like AWS Graviton, Google Axion, Microsoft Cobalt, Nvidia Grace, Alibaba Yitian will compete with better Neoverse cores. Nuvia vs ARM vs AmpereOne.
This is probably the golden age of server CPUs. 7 years ago, it was only Intel's Xeon. Now you have numerous options.

You're comparing it to the highest MSRP Turin, which doesn't have the highest performance/$. People buy that one if they want to maximize density or performance/watt, where it bests Ampere. If you only care about performance/$ you would look at the lower core count Zen5 (rather than Zen5c) models which have twice the performance/$ of the 192-core 9965.
Doing the same for Ampere doesn't work because their 192-core 3.2GHz model is very nearly already their peak performance/$.
The difference is, you can get EPYC CPUs but you can't get hold of Ampere CPUs.
Ampere's MSRP is pretty close to most system vendor is paying. You could expect most vendor buy EPYC or Xeon at close to 50% off MSRP.
Very exciting age, and very sad drop for intel, although as many have been warning, they should have seen it coming
AMD also wins on perf/Watt which is pretty notable for anyone who still believed that X86 could never challenge ARM/Risc in efficiency. These days, lot of data centers are also more limited by available Watts (and associated cooling) which bodes well for Turin.
