Intel Sapphire Rapids 56-Core ES CPU touches an amazing 3.3 GHz

Yuuki AnS, a Twitter user, has shared multiple screenshots that reveal details regarding Intel’s forthcoming Sapphire Rapids-SP 56-core processor. Like Intel’s mainstream Alder Lake processors, Sapphire Rapids will use Intel’s Golden Cove cores and Intel 7 node, formerly known as the 10nm Enhanced SuperFin technology.

According to the source, the Sapphire Rapids-SP CPU has 56 cores and 112 threads. On paper, AMD’s EPYC 7003 (Milan) CPUs have up to 64 cores and 128 threads, so they appear to be uninspiring. Regardless, it’ll be fascinating to witness Golden Cove take on Zen 3 in the data centre.

The Intel chip contains a total of 112MB L2 cache and 105MB L3 cache. The EPYC 7003 offers up to 256MB of L3 cache on the highest layer. Intel, on the other hand, is preparing Sapphire Rapids with up to 64GB of HBM2e memory, while AMD is preparing Milan-X chips with 512MB of 3D V-Cache.

Because the Yuuki-AnS Sapphire Rapids-SP processor is an engineering sample (ES), don’t take the clock speeds too seriously. The 56-core processor has a 1.9 GHz base clock and a 3.3 GHz boost clock so far.

The single-core boost clock on this Sapphire Rapids can reach up to 3.7 GHz

On Intel’s C741 (Emmitsburg) platform, the Sapphire Rapids-SP processor (ES2 QYFS) had 1TB of DDR5 memory with CL40-39-38-76 timings. The processor was installed on a Socket E (LGA4677) motherboard.

If the information is correct, the CPU has a 350W PL1 rating and a 420W PL2 rating. The actual BIOS-enforced power limit, on the other hand, is a monstrous 764W. The flagship Milan SKU, the EPYC Milan 7763, has a 280W TDP. The Twitter user did not specify the cooling system used by the Sapphire Rapids-SP processor. The Sapphire Rapids-SP chip, on the other hand, reached a temperature of 99 degrees Celsius, according to the article.

Sapphire Rapids was supposed to be released in the second quarter of this year, but it will now be released in the third due to delays. This will be a major issue for Intel, as AMD’s EPYC 7004 (Genoa) processors are expected to arrive around the same time. Genoa, unlike Milan, will use TSMC’s revolutionary 5nm process node and AMD’s Zen 4 cores. Genoa will also increase the number of cores on EPYC processors from 64 to 96, giving Sapphire Rapids a 96-core, 192-thread monster to fight with. As a result, Sapphire Rapids will be pressed for time.
