Full Intel 13th Gen Raptor Lake desktop CPU lineup leaks out, Core i9-13900K flagship detailed

A leak attributed to Twitter user @OneRaichu, described by HotHardware as a "known-good" leaker of Intel roadmap details, detailed cache and architecture upgrades expected across Intel's 13th Gen "Raptor Lake" desktop CPU lineup, in reporting published May 19, 2022. The flagship Core i9-13900K anchored the leaked lineup, according to the coverage.

Per HotHardware's reporting on the leak, Raptor Lake's per-core cache allocations grow substantially over the prior Alder Lake generation: L2 cache rises to 2MB per P-core, up from 1.25MB, and to 4MB per E-core cluster, up from 2MB. Total L3 cache rises to 36MB, up from 30MB in Alder Lake. Combined with additional E-core clusters, some coverage characterized the resulting total cache figure as roughly 68MB when L2 and L3 allocations are combined.

Separate wccftech reporting on the same leak wave described a fuller 14-processor lineup spanning four Core i9 models, four Core i7 models, five Core i5 models and a single Core i3 model, with the Core i9-13900K flagship configured with 24 cores and 32 threads in an 8 performance-core, 16 efficiency-core arrangement. That reporting cited a base clock of 3.0GHz, a single-core boost up to 5.8GHz, and an all-P-core boost of 5.5GHz. The two outlets' cache figures were broadly consistent with each other.

What's changing architecturally

Raptor Lake was reported to use Intel's enhanced Raptor Cove performance cores and Gracemont-derived efficiency cores on a refined Intel 7 process node, per the coverage. HotHardware's reporting noted Raptor Lake's expected launch in the second half of 2022, with compatibility carried forward for 600- and 700-series motherboard chipsets and continued DDR4 memory support alongside DDR5.

How the leak surfaced

The cache specifications originated from a CPU-Z validation screenshot shared by @OneRaichu, according to HotHardware, rather than an official Intel disclosure. The reporting did not specify how the leaker obtained the pre-release sample or validation data.

What it signals

The scale of the cache increase, alongside additional E-core clusters, pointed to Raptor Lake being positioned as a substantial refinement of Alder Lake's hybrid architecture rather than a ground-up redesign -- consistent with Intel's pattern of alternating major architecture changes with cache- and core-count-focused refreshes, though neither outlet's leak-based reporting confirmed final specifications, which remained subject to change ahead of an official launch.
