Matisse/Vermeer only support up to DDR4-3200 because the JEDEC standard stops there. Skylake only supporting DDR4-2933 is rather arbitrary.

But both AMD and Intel are regularly run with faster memory. Insisting on sticking to 'stock' memory speeds is a misguided refusal to acknowledge the popularity of XMP. Maybe juanrga's position made sense 15 years ago when faster than officially supported memory wasn't the default. Times have changed though.

Review sites today test with DDR4-3200 and faster simply because those are common configurations. Testing with slower memory only makes sense on locked Intel setups that enforce a memory speed limit.

Skylake is interesting because it's still Intel's fastest desktop architecture. Sunny Cove has better IPC and is ok-ish on low power/mobile, but on 10nm it can't reach clocks high enough to replace Skylake.

SKL losing to AMD architectures is just a demonstration of Intel's dated architecture falling further behind.
