Intel's next-gen Raptor Lake doubles cache sizes and matches AMD's Zen 4 thread count
A preview of Intel's next-gen CPU architecture, Raptor Lake, has popped up on the benchmarking site for SiSoftware Sandra(opens in new tab) (via Videocardz(opens in new tab)) and it promises some interesting things. First off, you have details about the Core i9 13900, plus there are some early benchmarks to pour over too.
The Core i9 13900 is a top-end chip boasting the same number of Performance cores as the current Core i9 12900 but with double the number of Efficient cores. That means you're looking at eight P-cores and 16 E-cores, for a total of 24 physical cores and 32-threads.
The Turbos of these cores appear to be lower than Alder Lake(opens in new tab), at 3.7GHz for the P-cores and 2.76GHz for the E-cores, but it is early days for the chip and is likely an engineering sample. This is also offset somewhat by having twice as many E-cores and also by the doubling of the L2 cache.
The L3 cache is also 20% larger. Raptor Lake also appears to support faster DDR5; at 5,600MT/s as opposed to 4,800MT/s. AMD's Zen 4(opens in new tab) is expected to support faster DDR5 right out of the gate, too, and it has already shown the impact of larger cache sizes with the Ryzen 7 5800X3D(opens in new tab).
After highlighting the lack of AVX512 support in Raptor Lake—a feature that was initially turned off in Alder Lake and then fused off altogether in later chips—and the fact that it will be present in Zen 4, the site then goes on to present expected performance for Intel's 13th-Gen architecture.
Though it's worth noting that SiSoftware hasn't directly tested this chip itself: «At publication time,» reads the report, «the products have not been directly tested by SiSoftware and thus the accuracy of the benchmark scores cannot be
