For the previous 5 years, AMD’s workstation-class Threadripper household has held an edge over Intel’s Xeon processors, both by way of worth/efficiency, most efficiency, or each. Whereas Ryzen has provided more and more troublesome competitors for Intel over time, AMD’s workstation edge has been bigger and extra constantly sustained than its client standing. Intel’s Alder Lake now affords a lot stronger competitors versus AMD and Intel is eager to duplicate that edge within the server market with its upcoming platform, Sapphire Rapids. Now, leaked benchmarks recommend Intel’s 56-core Sapphire Rapids will be capable to problem the 64-core Ryzen Threadripper 3990X.
This isn’t terribly stunning. The Threadripper 3990X is predicated on AMD’s Zen 2 structure, which suggests it’s lacking a ~15 p.c throughput enchancment it might decide up from being primarily based on Zen 3. These are leaked outcomes offered by @yuuki_ans, in order at all times, take them with a grain of salt and apply them judiciously. The Xeon 8470 Platinum in query seems to have a peak turbo clock of three.8GHz, however this might be as a result of the chip is an engineering pattern. Early ES CPUs are sometimes clocked decrease or produce other efficiency errata that gradual them down in comparison with last retail CPUs.

So far as comparisons to Threadripper are involved, our personal benchmarks confirmed the CPU at 25,790 in Cinebench R20, rising to 33,288 when overclocked to an all-core 4.3GHz. Whereas we don’t anticipate AMD to ship a Threadripper configuration like this, the 64-chip stays startlingly overclockable. In V-Ray, the Xeon Platinum 8470 hits 74,449, in comparison with 74,254 for a stock-clocked Threadripper 3990X.
AMD’s efficiency in CB20 was breathtaking — and nonetheless is, frankly, should you have a look at the overclocked numbers. I hit this overclock courtesy of a polar vortex that dropped exterior temperatures to ~10F.
It’s fascinating to see Sapphire Rapids profitable previous the Threadripper 3990X with simply 56 cores in comparison with AMD’s 64 — a 15 p.c core-count deficit is nothing to sneeze at, and AMD’s further cores have lengthy helped it win previous Intel within the enterprise and workstation market. These outcomes could clarify why AMD will pack as many as 96 cores in its upcoming Zen 4 platform. Rising core counts affords the smaller firm a stable likelihood of staying forward of the competitors, significantly when mixed with the single-thread enhancements Zen 4 will carry to the desk.
The opposite factor to recollect a few chip like Sapphire Rapids is that it has way more reminiscence bandwidth than the Ryzen Threadripper 3990X. AMD’s top-end workstation CPU is proscribed to 4 channels of DDR4, whereas Sapphire Rapids has eight channels of DDR5. We’d not anticipate this to affect Cinebench outcomes — that take a look at is kind of core-centric and is minimally impacted by the reminiscence subsystem — however efficiency in different benchmarks may completely be impacted.
Intel has been aggressively pushing its personal efficiency and product introductions and we anticipate that to proceed in 2022 – 2023. AMD has executed nicely up to now within the face of a resurgent Intel, however Zen 4 might want to hit the market firing on all thrusters when it arrives later this 12 months.
