Briefly: Leaked benchmarks are giving us a style of Intel’s upcoming Granite Fast server chips’ unbelievable specs – assume 120 P-cores and 240 threads. With practically 1.5GB of complete cache in a twin state, these chips seem like they’ve AMD’s newest Epyc choices squarely of their sights.
The primary Granite Rapids chip to floor is the Xeon 6900P, which was not too long ago noticed on Geekbench by the leak account BenchLeaks. This 120-P-core, 240-thread beast achieved a single-core rating of 1,021 and a multi-core rating of seven,155 in a dual-CPU setup operating Ubuntu 24.04 LTS.
However that is simply the tip of the iceberg. The 6900P is rocking a large 744MB of complete cache, break up between 240MB of L2 and 504MB of L3. With practically a gigabyte of cache, it leaves Intel’s present chip kings – Emerald Rapids and Sapphire Rapids – within the mud.

Maybe extra impressively, the chip was capped at a lowly 1.8GHz base clock, so it undoubtedly wasn’t flexing its full efficiency potential. Furthermore, that is nonetheless an engineering pattern, so you possibly can principally ditch these numbers because the precise product will possible carry out very in a different way.
Nevertheless, even on this hobbled state, a twin 6900P setup boasts 240-cores and 480-threads with practically 1.5GB of complete cache. Slap it in a system with 2TB of DDR5 reminiscence just like the take a look at rig, and you have a superb number-crunching machine.
After all, with nice energy comes… properly, nice energy consumption. Leaks counsel the highest Granite Rapids chips may eat over 500 watts apiece. A dual-socket config is principally a large 1kW-sipping unit at that time. However if you’re constructing dense information middle servers, configuring them with elaborate cooling is simply a part of the bundle.
Granite Rapids is slated to launch someday in 2024, going head-to-head with AMD’s upcoming 128-core Zen 5 Epyc chips. There’s additionally an E-core centered Sierra Forest model coming down the pipeline, scaling as much as a ridiculous 288 cores to battle AMD’s 192-core Zen 5c models.
