GPU: Intel’s on-chip graphics processor comes in a variety of configurations. The larger the cache, the less time the CPU is likely to waste waiting for the data it needs. On a few high-end desktop chips (denoted with a K suffix) the Turbo multipliers are unlocked, so you can make the processor run as quickly as you like – although if you go too far, the chip may overheat, or automatically dial down the speed to avoid a crash.Ĭache: Loading program and data code from system memory into the CPU is comparatively slow performance can be greatly improved by equipping the processor with its own super-fast RAM cache. Our table shows the highest speed boost offered by any processor model in each family of chips. The extent of the boost varies depending on the precise specification of the processor, and on how much power the other cores are consuming at the time.

Max Turbo: On Core i5 and i7 processors, Intel’s Turbo Boost technology automatically increases the speed of individual processor cores when they’re busy.
