Early Intel 13th Gen Raptor Lake i9-13900 review suggests AMD Ryzen 7000 could be king

With heavily vectorised SIMD workloads – RPL cannot beat ADL by more than 4-6% and thus generally even lose to the AVX512-enabled RKL with just 16-threads (vs. 32T on RPL). This shows just how much AVX512 can help despite the extra power required – and here it is hugely missed. However, AMD’s Zen3 (5900X) with less threads (24T) but 12 big cores (vs. 8C + 16c) still beats RPL by a decent margin and this is not great news for Intel. With AMD’s forthcoming Zen4 supporting AVX512, RPL is likely to be severely beaten into dust – by perhaps as much as 2x (100%). Intel will, again, have to rely on non-SIMD workloads/benchmarks (Cinebench?) to show performance leadership.

• 10nm+++ (Intel 7+) improved process
• Unified 36MB L3 cache (vs. 30MB on ADL thus 20% larger)
• Up to 8C/16T “Raptor Cove” (!) cores – improved from “Golden Cove” in ADL
• DDR5/LP-DDR5 memory controller support (e.g. 4x 32-bit channels) – up to 5600Mt/s (official, vs. 4800Mt/s ADL)
• L2 increased to 2MB per core (almost 2x ADL) like server parts (ADL-EX)
• Up to 16c/16T “Gracemont” cores – thus 2x more than ADL but same core
• L2 4MB shared by 4 cores (2x larger than ADL)
