Intel 10nm Ice Lake-SP Twin 28C/56T ES CPU Benchmarks Leak And Indicate AMD Might Just Race Ahead With Its 56C/112T AMD EPYC 7742 Processor?

Intel’s next-generation CPUs based on Ice Lake-SP, and manufactured on the 10nm Fabrication Node, have been steadily appearing in various configurations. The latest benchmark leaks about a mystery Intel Ice Lake-SP CPU in a twin configuration with 28 Cores and 56 Threads each, offer some interesting information. These CPUs are clearly meant for the Xeon server application and hence will now compete against AMD’s EPYC Milan platform.

Two new benchmark results about a mystery Intel 10nm Ice Lake-SP CPU have leaked out. The unidentified CPU is in a twin layout configuration, which should be part of the next-gen Intel Xeon server-grade CPU lineup. While Intel was clearly trying to go up against AMD’s second generation of EPYC Rome lineup, these CPUs will now have to compete against the third generation of AMD EPYC Milan CPUs.

Intel’s Next-Gen 10nm Ice Lake-SP CPUs With Two 28C/56T Chips Leak In Two Benchmarks:

Packing Whitley Cores, the Intel Ice Lake-SP CPU lineup will be composed of several Xeon server-grade CPUs. There have been reports of CPUs with 6 Core 12 Thread as well as 24 Core 48 Threads configuration. A new unidentified 28 Core 56 Thread Intel CPU from the same family has been spotted in the Geekbench database as well as in the SiSoftware database.

The testbench comprised of Intel Ice Lake-SP CPU slotted inside a dual-socket server motherboard. Each chip features 28 cores and 56 threads which round up to 56 cores and 112 threads in total. It is important to note that these CPUs could easily be a part of early-stage engineering samples. This explains the lower Base Clock speeds of just 1.5 GHz, and up to 3.20 GHz Boost Clock speeds.

The 2S Ice Lake-SP server testbench packed 512 GB of memory which should be clocked at 3200 MHz. The memory was arranged in an 8-channel configuration, which is one of the key highlights of the new Whitley platform.

Coming to the benchmark results, the server scored up to 3443 points in single-core tests and 37317 points in multi-core tests. Needless to add, these numbers are quite low, and furthermore, these could easily be due to the prototype nature of the chips.

How Does Intel’s Next-Gen 10nm Ice Lake-SP CPUs Compare Against AMD’s EPYC Milan 7742 CPU Setup?

Intel is clearly trying hard to build its latest 10nm Fabrication Node. The Whitley Architecture inside the Ice Lake-SP CPUs is one of the truly big leaps in production and CPU structure refinement for Intel. Hence the early benchmark results should transform and final performance is expected to be much better.

Incidentally, the Intel CPUs benefit in this benchmark from their AVX-512 instruction set which the AMD CPUs lack. Additionally, the Intel CPU benchmarks appear to have been performed on two different operating system environments. Meanwhile, the EPYC 7742 CPU was reportedly tested solely on a Windows 10 server setup.

A single AMD Milan EPYC 7742 CPU comprises of a total of 64 cores and 128 threads. Intel on the other hand needs two Ice Lake-SP CPUs that offer a total of 56 cores and 112 threads. As the results indicate, the AMD EPYC 7742 CPU easily outperforms the Intel chips in single-core tests. However, this is because AMD’s CPU has already reached 3.4GHz, whereas Intel’s CPU is still under development, and reached just 1.5GHz.

Interestingly, the AMD platform managed to reach around 35,000 points in multi-core tests, which is slightly lower than the Intel Ice Lake-SP parts which managed to cross 38,000. This could mean the final or commercially-ready Intel Ice Lake-SP CPUs might outperform the AMD EPYC Rome, but the margin might not be as wide as Intel would invariably desire.
