Intel’s upcoming “tock” microarchitecture is expected make its appearance on the desktop next spring, according to most reports. Today we are getting a look at the speculated model lineup, as VR Zone China has leaked some slides that give us an idea of what to expect for the first time.
There are some interesting figures there, most notably an increase in TDP from 77W on the current Ivy Bridge lineup, to 84W with Haswell (32nm Sandy Bridge was 95W at the top end). This is probably due to the integrated GPU, which is expected to be much more capable than Intel’s current offerings. How it will compare to AMD’s APU will be interesting to see.
It looks like there will only be two low voltage versions of Haswell for the desktop, in the form of the Core i7 4765T, and the dual core i5 4570T, both with a 35W TDP. It is possible that Intel will do a staggered release like they did with Ivy Bridge, where the initial lineup will consist of Core i5 and Core i7, with Core i3 chips to follow later in the year.
Other than that, not much is new. Clock speeds remain under 4 GHz at turbo still, the maximum memory clock is still 1600 MHz, and there is still 8MB of L3 cache. Of course, this doesn’t mention the huge amount of internal changes that will be made to the chip, which is what we will write about when the time comes. When Intel releases a “tock” chip, it is usually quite a bit faster than the last one at the same clock speed.
