TechSpot: Haswell Refresh - Intel's New Z97 Platform Explored

Nearly six years have passed since the Core i7 series debuted as a 45nm part on the LGA1366 platform. Codenamed Bloomfield, Intel's Nehalem-based quad-core lineup included the celebrated Core i7-920 and has since been refined over many iterations through Intel's tick-tock philosophy, which follows every architectural update with a die shrink.

Today's release isn't a tick or a tock, it's simply a refresh -- and as such we don't expect much more than 100MHz speed bumps.

Until Intel is ready to ship Broadwell, it has tweaked the Haswell range with models that are slightly faster and/or cheaper. If anything, your attention should be on the fact that Intel has also released its new 9-series chipsets, and we happen to have a few motherboards on hand. Before we check those out, let's cover what may as well be called Haswell 1.1.

From what I've read the i7 4770 (the part just below the new 4790 they've released today) is about 10% faster than the 3770 which in turn is about 10% faster than the 2600 from 2011 (I have the 2600K).

So if that's correct if I upgraded my PC to this platform I'd be looking at maybe a 20-30% boost in CPU speed (1.1 * 1.1 = 1.21 then top that up a bit to allow for chipset improvements etc).

My current CPU is already blisteringly fast and for all but the most extreme tasks is going to show no difference at all from these new chips. This is a 3 year old CPU.

So I really don't see any reason to get too worked up about these new chips compared to the older ones. The really exciting thing about them is the reduced power consumption - but that applies most in devices like ultrabooks rather than desktop PCs.

I'm sure you can find a benchmark that shows that big differences. However, real world performance of all these "new" Intel chips is identical. If you are into overclocking, you can most likely get more performance out of a good old Sandy Bridge than the Haswells.
