The one to go for?
Chip giant Intel launched its 3rd Generation Core chips on Monday. Previously known by the codename of Ivy Bridge, these new processors add a touch more CPU speed and around 30 per cent extra graphics performance over that exhibited by price-comparable 2nd Generation Core models hewn from Sandy Bridge silicon.
While manufacturing concerns don't mean a great deal to the average consumer, Intel is using a 22nm, Tri-Gate process for these new chips. This should mean they're cheaper to produce and consume less power than 2nd Generation Core processors. We reviewed the top-of-the-range Core i7-3770K on launch day, though you shan't be able to purchase one until Monday 30th April, such is Intel's wont.
The Daddy chip's retail pricing is set to be around £230 and, while relatively inexpensive in the grand scheme of Intel processors, the bulk of 3rd Generation Core sales are sure to occur at lower price points. Going back a generation we reckoned that the four-core, four-threaded Core i5-2500K was a good bet, priced at around £160, as it provided solid performance for both everyday tasks and gaming. The equivalent 3rd Generation Core chip is the Core i5-3570K, due to be available for the same sort of money, so it's well worth a good look.

Shamelessly ripping off the table in the original review, we can discern at least three differences between the mid-pack Core chips of the two Intel families. Priced within a few dollars of each other, the 3570K is clocked in a little higher, both in term of base and Turbo Boost speeds, has the same-clocked graphics as the top-line part - Core i5-2500K's are clocked in lower than 2700K's - and 3570K ships with a lower TDP than its Sandy Bridge counterpart. These factors alone make it, on paper, a better buy than its predecessor. Do be aware that Intel has quietly slipped in the Core i5-2550K, which is clocked in at the same speeds as the Core i5-3570K, albeit without the goodness of integrated graphics. And we thought Intel had simplified its line-up!
The Core i5-3570K is arguably a more-important chip than the Core i7-3770K, mainly because its lower price point makes it more attractive to enthusiasts on a (relative) budget and to system integrators (SIs) looking to hit the all-important £999 price point for a well-specified base unit. The K nature of the processor means that it's multiplier-unlocked, enabling simple overclocking by increasing the CPU ratio (multiplier), and it's by this method that SIs release pre-overclocked machines.
The two questions we need to answer in this review go something like this: how much better is the Core i5-3570K than the much-used, popular Core i5-2500K, and is the gap large enough to persuade owners of relatively new systems to jump ship and opt for the shiniest technology Intel has to offer? Let's find out.
