In the case I was thinking of, Skylake-X, the HEDT line, that wasn't entirely true. I was looking mostly at something like Broadwell-E vs Skylake-X, where the difference is huge:
Core i7-6950X - $1,700 at launch in 05-2016: 10 × 256 KiB of L2, with 25 MiB of L3.
Core i9-7960X - $1,700 at launch in 09-2017: 16 x 1024 KiB of L2, with 22 MiB of L3.
- tntn 7y agoi7-6950X: 256 KiB L2/core, 2.5 MiB L3/core i9-7960X: 1024 KiB L2/core, 1.375 MiB L3/core Seems to be exactly what I described? L2/core went up by 768 KiB, L3/core went down by 1.125 MiB.
- ivl 7y agoL3 went down per core, but total L3 only fell by 3 MiB. While total L2 flew up from 2.5 MiB to 16 MiB in a single generation for two processors that target the same segment at the same price. Per core you're correct, but I was looking at net cache available, as that had been remaining static, usually just seeing an extra 256 KiB of L2 per core with little L3 change.
