"Where Ampere and the Altra definitely is beating AMD in is TCO, or total cost of ownership.

Of course, performance/$ will vary depending on workloads, but the Altra’s performance is so good that I don’t think it really changes the narrative of that large a cost difference. We’re really on basing this on both companies’ MSRP prices and we know for a fact many customers will be paying less than that for volume purchases and relying on discounts, but that can also apply to Ampere and the Altra.
One will note I didn’t make any mention of Intel yet - Intel’s current Xeon offering simply isn’t competitive in any way or form at this moment in time. Cascade Lake is twice as slow and half as efficient – so unless Intel is giving away the chips at a fraction of a price, they really make no sense. Ice Lake-SP is around the corner, but I don’t expect it to manage to bridge the performance or efficiency gap. Ampere and AMD here have free reign on the server market share – with Ampere having to cross the hurdle to convince customers to switch over from x86 to Arm."

Ampere je predstavio najnoviji ARM serverski Altra Q80-33 SoC.
https://amperecomputing.com/altra/
https://www.arm.com/products/silicon-ip-cpu/neoverse/neoverse-n1
Altra SoC je baziran na high performanse ARM Neoverse N1 CPU arhitekturi. Ampere SoC proizveden je na TSMC 7nm proizvodnom procesu.
- 80 CPU jezgri, nema SMT-a 80C/80T
- do 4TB radne memorije po socketu
- radna CPU frekvencija do 3.3ghz
- 128 PCIe Gen4 stazica po socketu
- TDP 250W
- cijena 4050$
U testovima koristi se dual socket Ampere konfiguracija. Dakle tu je ukupno 160 CPU jezgri, i s obzirom na to dual socket kombinacija ima 500W TDP
Serverska konkurencija je AMD Eypc 7742(64C/128T) i Intel Xeon 8280(28C/56T), opet u dual socket konfiguracijama.
