Intel Sapphire Rapids-SP Subsequent-Gen Xeon CPU SKUs Leak Out – Up To 56 Cores, 105 MB Cache & 350W TDPs

Written by Jeff Lampkin

A number of Intel Sapphire Rapids-SP Xeon CPUs have leaked out together with their particular core, cache, and TDP configurations. The leak comes from Yuuki_Ans who has acquired the spec sheet together with footage of early engineering boards that includes the next-gen Xeon SOCs.

Intel’s Subsequent-Gen Sapphire Rapids-SP Xeon CPUs Leak Out – Up To 56 Cores, 105 MB Cache & 350W TDP

There are at the very least 10 Intel sapphire Rapids-SP Xeon SKUs listed inside the specs sheet, all of which characteristic totally different core counts, cache sizes, and TDPs. The Sapphire Rapids-SP lineup might be based mostly on the ‘Intel 7’ course of node and have Golden Cove core structure to energy as much as 56 cores. Following are the leaked configurations:

  • Sapphire Rapids-SP 24 Core / 48 Thread / 45.0 MB / 225W
  • Sapphire Rapids-SP 28 Core / 56 Thread / 52.5 MB / 250W
  • Sapphire Rapids-SP 40 Core / 48 Thread / 75.0 MB / 300W
  • Sapphire Rapids-SP 44 Core / 88 Thread / 82.5 MB / 270W
  • Sapphire Rapids-SP 48 Core / 96 Thread / 90.0 MB / 350W
  • Sapphire Rapids-SP 56 Core / 112 Thread / 105 MB / 350W

Out of all these SKUs, clock speeds for the 24 core, 28 core, and 48 core Intel Sapphire Rapids-SP Xeon CPUs are listed. These are early samples so count on them to be far decrease than what the retail specs are going to supply. The 28 core and 48 core fashions are rated at 1.3 GHz whereas the 24 core is rated at 1.5 GHz. These are additionally base clocks and I personally count on them to peak out at round 3.5-4.0 GHz. The remainder of the SKUs line in with the leaked specs from some time again which will be learn intimately beneath.

Here is The whole lot We Know About Intel’s 4th Gen Sapphire Rapids Xeon CPUs

The Sapphire Rapids-SP household might be changing the Ice Lake-SP household and can go all on board with the 10nm Enhanced SuperFin course of node that might be making its formal debut later this 12 months within the Alder Lake client household. From what we all know thus far, Intel’s Sapphire Rapids-SP lineup is anticipated to make the most of the Golden Cove structure & might be based mostly on the 10nm Enhanced SuperFin course of node.

The Sapphire Rapids lineup will make use of 8 channel DDR5 reminiscence with speeds of as much as 4800 Mbps & help PCIe Gen 5.0 on the Eagle Stream platform. The Eagle Stream platform will even introduce the LGA 4677 socket which might be changing the LGA 4189 socket for Intel’s upcoming Cedar Island & Whitley platform which might home Cooper Lake-SP and Ice Lake-SP processors, respectively. The Intel Sapphire Rapids-SP Xeon CPUs will even include CXL 1.1 interconnect that may mark an enormous milestone for the blue crew within the server section.

Coming to the configurations, the highest half is began to characteristic 56 cores with a TDP of 350W. What’s fascinating about this configuration is that it’s listed as a low-bin break up variant which implies that it is going to be utilizing a tile or MCM design. The Sapphire Rapids-SP Xeon CPU might be composed of a 4-tile format with every tile that includes 14 cores every.

It seems to be like AMD will nonetheless maintain the higher hand within the variety of cores & threads provided per CPU with their Genoa chips pushing for as much as 96 cores whereas Intel Xeon chips would max out at 56 cores if they do not plan on making SKUs with a better variety of tiles. Intel can have a wider and extra expandable platform that may help as much as 8 CPUs without delay so except Genoa gives greater than 2P (dual-socket) configurations, Intel can have the lead in essentially the most variety of cores per rack with an 8S rack packing as much as 448 cores and 896 threads.

The Intel Saphhire Rapids CPUs will include 4 HBM2 stacks with a most reminiscence of 64 GB (16GB every). The overall bandwidth from these stacks might be 1 TB/s. In keeping with leaked particulars from AdoredTV, HBM2 and GDDR5 will have the ability to work collectively in flat, caching/2LM, and hybrid modes. The presence of reminiscence so close to to the die would do absolute wonders for sure workloads that require big knowledge units and can principally act as an L4 cache.

AMD has been taking away fairly just a few wins from Intel as seen within the current Top500 charts from ISC ’21. Intel would actually need to up their recreation within the subsequent couple of years to struggle again the AMD EPYC risk. Intel is anticipated to launch Sapphire Rapids-SP in 2023 adopted by HBM variants which can be anticipated to launch round 2023.

Which server lineup do you suppose will supply the most effective characteristic set for enterprise markets?
