Unless you count them, you may not notice the reduction in the number of connection pads (1,155) from the previous generation of Core i7 chips (1,156). On the CPU die, in addition to the four cores, is Intel's HD Graphics module, which is fully integrated on the ring bus and shares the top-level cache with the processing cores, boosting performance. We haven't made use of that in our system, however, opting instead to install an nNvidia PCI-E card. The range-topping Core i7-2600K supports overclocking and is aimed at those requiring maximum performance, yet consumes only 95W.
