We've already seen plenty of rumours and leaks
about Intel's Core i7-990X, but the unreleased chip has now been unofficially confirmed by a motherboard manufacturer. ECS decided to update its website early, leaking all the info about the chip in the process. You just need to head over to the page for ECS' X58B-A3 SLI motherboard
and click on the CPU tab to see for yourself.
According to the site, the Core i7-990X runs at 3.46GHz, although the TurboBoost speed hasn't been revealed yet. ECS also says the CPU will have a toasty TDP of 135W, which is 5W higher than the TDP of the Core i7-980X.
Otherwise, the chip looks basically the same as the 980X, featuring B1 stepping and 12MB of Level 3 cache, meaning this chip is basically just a clock-bumped six-core CPU.
