According to the latest round of leaked Intel roadmaps, Ivy Bridge is due in the second quarter of next year. We've already discussed the selection of models being prepared to replace the existing Sandy Bridge lineup of Core processors. Now, Xbit Labs has published purportedly leaked slides detailing how the new silicon stacks up against its predecessor.
A couple of official-looking Intel slides compare the performance of the Core i7-2600 to that of the upcoming i7-3770, which has the same core count, base clock speed, and cache size. The i7-3770 is purportedly 7-25% faster across a range of tests that stress the CPU, although it's fair to note that the chip's 3.9GHz Turbo peak is 100MHz faster than the i7-2600's maximum speed.
Perhaps more interesting are the performance results from tests that tap the integrated graphics. "ArcSoft Media Expresso," which is perhaps what happens when the folks making the presentation slides confuse ArcSoft's MediaConverter software with CyberLink's MediaEspresso product, is said to be 56% faster on Ivy Bridge. Both of those applications support Intel's QuickSync transcoding tech. Ivy's integrated graphics component scores three times higher than Sandy's in 3DMark Vantage, as well. Keep in mind that the Core i7-2600 has the slower HD 2000 version of Sandy Bridge's integrated graphics, while the i7-3770 is expected to have the fastest version of the new IGP, dubbed the HD 4000.
What's especially remarkable about these results is that Ivy Bridge's CPU cores should be able to deliver performance improvements while at the same time drawing less power than their predecessors. The i7-2600 has a 95W TDP, while the i7-3770 is supposed to consume less than 77W. That lower TDP suggests Ivy Bridge will have more relaxed cooling requirements than its predecessor, and the chip could prove to be a more potent overclocker as a result.
