Qualcomm Oryon CPU avec Flex Cache

Qualcomm hits 5GHz on a phone CPU, but Flex Cache may be the more important upgrade

Qualcomm has pushed its next mobile Oryon CPU to the symbolic 5GHz mark. That will inevitably dominate benchmark comparisons, but the accompanying Flex Cache architecture is arguably the more consequential change. Different classes of CPU core can access the same dynamically allocated cache pool, letting demanding workloads retain larger working sets close to the cores instead of spilling them back to system memory. On a thermally constrained, battery-powered device, avoiding DRAM traffic can matter as much as adding clock speed.
