Do you hear that noise? If it sounds like a "Tock!," that's because Intel's 22nm Haswell refresh is here, though calling it a refresh may not do justice to the new microarchitecture. Haswell is a Tock in Intel's "Tick-Tock" cycle, meaning it's a major new microarchitecture that will set the foundation for new and upcoming desktop processors. Several Haswell chips are now available to order, including the high end Core i7 4770K part, which you can snag for just $280 if you happen to live near a Micro Center.
Unfortunately, there are less than two dozen Micro Center locations (23, to be precise) spread across 16 states, and the deal doesn't apply to online orders. Bummer.
The Core i7 4770K part is a quad-core chip with a base frequency of 3.5GHz and Turbo speed of 3.9GHz. It has 8MB of L3 cache, 84W TDP, and an unlocked multiplier as denoted by the "K" in the model number. It's the fastest desktop Haswell chip currently available.
In any event, here's a heads up for those of you within striking distance of a Micro Center. For everyone else, the chip streets for about $350 online, including Newegg, which is bundling a Grid 2 game coupon and Grid 2 t-shirt with purchase.
