[Tom's Hardware] Dual Intel Xeon Ice Lake-SP CPUs Seemingly Tested: 10nm Chips Take on AMD EPYC 7742

A lot of excitement surrounds Intel's looming Xeon Ice Lake-SP chips, as they will be the first non-mobile CPUs to represent the chipmaker's 10nm process node. As spotted today by @TUM_APISAK, a fresh pair of 28-core chips have landed on the Geekbench 4 benchmark and could offer a glimpse of what to expect from Ice Lake-SP.

Ice Lake-SP is destined to replace Intel's current Cascade Lake offerings. Besides exploiting the 10nm+ manufacturing process, these Ice Lake server chips are expected to usher in the Sunny Cove microarchitecture, as well as support for up to 64 speedy PCIe 4.0 lanes. The core-heavy processors will likely descend upon the Whitley platform, which commands the new LGA4189 socket.

An unconfirmed slide from last year suggests that Ice Lake-SP will land with octa-channel memory support and natively embrace DDR4-3200 RAM modules.

The processors were also said to be compatible with Intel's second-generation Optane DC Persistent Memory (Barlow Pass). The slide implies that Ice Lake-SP will stop at 38 CPU cores, meaning the alleged 28-core that we're seeing today might not be the flagship chip.
Looks like they improved their SMT performance

Would be interesting to see how much power they use considering its 1 v 2.

The two processors with a combined 56 cores beat a 64 core AMD Epyc by a little less than 10% in multicore, while losing pretty hard in single core due to the really low base clocks.

It doesn't tell us very much at all, other than that there are 28 core processors based on Ice Lake out there somewhere. To me this suggests that intel's 10nm node is still extremely immature. A a 28 core processor at those clock speeds, even with the IPC advantages of Ice Lake, is not something that will be competitive. They have to do better.

Which will have to face Zen3 Epyc.

Well geek bench uses AVX512 so its not a real world benchmark.

Tell that to all the researchers that utilize AVX-512 daily. AMD announced they were looking into AI specific instructions so I wouldn't be shocked if Milan has similar instruction sets.

So, statistically insignificant to the point of effectively not existing. The textbook definition of not a real world test.

If AMD is "looking into" it within the last year, it isn't happening for at least four or five years. Zen3 was a finished designs years ago.

GeekBench definitely isn't a real world test. Stating the use of AVX-512 isn't a real world test just because your competition doesn't have it doesn't magically make it an unreal test. Especially when these parts are targeting HPC.

We get it you don't like Intel, if it was insignificant they wouldn't of had a record breaking quarter for the data center.

It's not insignificant, it's just irrelevant. If you can't compare apples to apples, then it's not a valid test. That's always been the point.

How's it not relevant? Just because the competition doesn't have similar functionality? That's like me comparing a Radeon Pro VII against a Quadro RTX 5000 and not using the RT cores/Tensor cores just because the competition doesn't have it.
