Intel 3rd Gen Ice Lake-SP Xeon CPU With 14 Cores & 28 Threads Benchmarked


Fairly just a few benchmarks of Intel’s third Gen Ice Lake-SP Xeon CPU have leaked out which present a 14 core and 28 thread half and its respective outcomes inside numerous assessments. The Ice Lake-SP Xeon lineup shall be launched subsequent 12 months as Intel just lately confirmed and shall be based mostly on the brand new Ice Lake 10nm+ ‘Sunny Cove’ core structure.

Intel Ice Lake-SP Xeon Silver 14 Core & 28 Thread CPU Benchmarked – Single-Core Efficiency On Par With Core i9-10900K In ES State However Thanks To AVX-512

The CPU proven is an Ice Lake-SP Xeon Silver chip which is in an early engineering state. The chip options 14 cores and 28 threads. There’s 17.5 MB of L2 and 21 MB of L3 cache onboard. Leaker YuuKi_AnS states that the chip has a base clock of two.0 GHz and a lift clock of 4.0 GHz nevertheless the precise enhance working vary is between 1.8 to 2.0 GHz when working all cores.

This may very well be partially because of the ES nature of this chip. The Xeon Silver Ice Lake-SP CPU comes with a 165W TDP and a most working temperature vary of 105C. The CPU is meant for use on the LGA 4189-5 socket. Based on the leaker, the chip may very well be a part of the Xeon Silver 4300 line which is anticipated to launch subsequent 12 months.


Coming to the take a look at outcomes, the Intel Ice Lake-SP Xeon CPU scores 553.1 factors in a single-core and 10038.4 factors within the multi-core take a look at. The one-core outcomes put the Xeon chip neck-to-neck with a Core i9-10900K which is Intel’s quickest gaming chip that enhances as much as 5.3 GHz. That is spectacular for an engineering pattern that is working at vastly decrease clock speeds. In multi-core assessments, the Xeon-SP ES CPU is about as quick because the Ryzen 9 3950X which is a 16 core and 32 thread half. This could put the Xeon-SP CPU in the identical ballpark because the Ryzen 9 5900X which is a 12 core and 24 thread half however with a lot greater multi-threaded efficiency over its predecessor because of the Zen 3 core structure.

Nonetheless, there’s one factor to notice that the most recent CPU-z model was used which makes full use of AVX-512 and that could be a main contributor to Intel’s efficiency right here. With out AVX-512 acceleration, the Intel Ice Lake-SP Xeon ES CPU is far slower, scoring simply 371.6 factors in single-core and 6363 factors in multi-threaded assessments. Different benchmarks embody Fritz Chess the place the chip scores 19715 factors which is simply barely quicker than a first-generation 8 core and 16 thread Ryzen CPU.


The leaker additionally posted some delidded photos of the Intel Ice Lake-SP CPU which seems to characteristic a soldered design with gold solder and high-quality liquid metallic thermal compound. The silicon lies on a separate bundle interposer that sits on prime of the primary PCB. One other attention-grabbing element that’s uncovered by this delid which might additionally in any other case stay hidden is the truth that the chip makes use of an HCC (Excessive Core Depend) die and never the XCC (Excessive Core Depend) ones that enable for extra cores.

A few of the main upgrades that Intel’s 10nm+ for Ice Lake-SP Xeon CPU will ship embody:

  • 2.7x density scaling vs 14nm
  • Self-aligned Quad-Patterning
  • Contact Over Lively Gate
  • Cobalt Interconnect (M0, M1)
  • 1st Gen Foveros 3D Stacking
  • 2nd Gen EMIB

The Intel Ice Lake-SP lineup can be immediately competing towards AMD’s enhanced 7nm based EPYC Milan lineup which is able to characteristic the brand new 7nm Zen 3 core architecture which gives an enormous 19 % uplift in IPC over the unique Zen core.
