AMD Threadripper competitor has up to 336MB of L3 cache



First, Granite Rapids is not to be mistaken for Granite Ridge. The latter is a codename for current desktop Ryzen 9000 series based on Zen5 architecture, the former is Intel Xeon CPU lineup for servers and soon for workstations. It seems to be coming soon given that the full linuep was shared by leaker “momomo_us” and an early Geekbench entry for the Xeon 654 give the first clear look at how Intel is adapting its Xeon 6 P-core dies for workstations rather than datacenters.

The leaked stack mentions at least eleven Granite Rapids-WS parts: 698X, 696X, 678X, 676X, 674X, 658X, 656, 654, 638, 636 and 634. Only base clocks and L3 cache sizes are shown. The flagship Xeon 698X is listed at 2.0 GHz with 336 MB of cache, while the 696X bumps base clock to 2.4 GHz at the same cache size. At the other end, Xeon 634 carries 48 MB of cache at 2.7 GHz. The middle of the stack includes chips such as the 678X at 2.4 GHz with 192 MB and several 72 MB SKUs in the 3.0–3.2 GHz range.

The first benchmarked part, Xeon 654 may help us with navigating through the specs. Geekbench reports 18 cores and 32 threads for this chip, with scores of 2,634 points in single-core and 14,743 points in multi-core tests. Boost clock is logged at 4.77 GHz with a minimum reported clock of 2.9 GHz, close to the 3.1 GHz base frequency from the leak. The same SKU list puts Xeon 654 at 72 MB of cache, matching the small-cache entries in the table.
