Intel Sapphire Rapids leak offers sneak peek at specs and performance

New details have emerged regarding Intel’s upcoming Sapphire Rapids-SP 56 central processor, intended for use in data centers.

According to a new report from Tom’s gearleaky material YuuKi_AnS once again provided more information on the chip giant’s Sapphire Rapids processors after comparing them in February this year.

Much like its Alder Lake processors, Sapphire Rapids will take advantage of Intel’s Golden Cove cores and the Intel Node 7, which was previously known as the 10nm enhanced SuperFin process.

According to screenshots that YuuKi-Ans shared on Twitter, the leaked Sapphire Rapids-SP processor has 56 cores and 112 threads. While we don’t yet know how it will perform in real-world testing, the new chip is dwarfed by AMD’s EPYC 7003 (Milan) chips which have up to 64 cores and 128 threads.

In addition to its 56 cores and 112 threads, Intel’s Sapphire Rapids-SP chip has 112 MB of L2 cache and 105 MB of L3 cache. Again though, the top of the line EPYC 7003 beats it with up to 256MB of L3 cache.

Nevertheless, Intel is preparing a Sapphire Rapids chip with up to 64 GB of HBM23 memory while AMD’s Milan-X chips will include 512 MB of 3D V-Cache.

It’s also worth noting that the Sapphire Rapids-SP CPU leaked by YuuKi-AnS is an engineering sample, so things could change when the chip goes into production. Anyway, the leaked processor has a base clock of 1.9 GHz and can boost up to 3.3 GHz. Meanwhile, the single-core boost clock can reach speeds of up to 3.7 GHz.

Intel’s Sapphire Rapids-SP processor power supply will require a significant amount of power as it has a PL1 rating of 350W according to screenshots by YuuKi-AnS and a PL2 rating of 420W. However, the limit actual power applied from inside the BIOS is up to 764 W and the chip itself can reach a maximum temperature of 99 degrees Celsius.

Although Sapphire Rapids was supposed to be released in the second quarter of 2022, delays pushed its release to the third quarter of this year. These delays also mean that Intel’s new data center chip may have to contend with AMD’s EPYC 7004 (Genoa) which could arrive around the same time.
