Back when Intel unveiled the Skylake microarchitecture, Intel proceeded to rebalance the cache structure of its CPUs within the HEDT lineup. According to Geekbench, a similar cache rebalancing may be coming to the upcoming 10nm Tiger Lake mobile CPUs.

Assuming Intel follows similar actions taken prior to the release of HEDT Skylake-X CPUs, Intel may continue the trend to Tiger Lake. In the case of Skylake-X, Intel reduced the amount of L3 cache in favor of increased lower-latency L2 cache, though, with Tiger Lake-Y, Intel may bring improvements in each L1, L2, and L3 caches. Previously, mobile and desktop CPUs shared the same cache structure, but with a redesign of the cache, Intel could bring increased efficiency to mobile CPUs.
