Ivy Bridge desktop CPU lineup details, part II

Today we published details of upcoming Ivy Bridge microprocessors, that were leaked by Zol.com.cn news site. As soon as we published the story, we discovered that more detailed list of Ivy Bridge models was leaked by corescn website. The corescn site blocked access to the thread with processor information, however copy of one slide is available in ComputerBase forum.

The new slide confirms basic specifications from Zol.com.cn slides. That is, the third generation Core i7 processors will integrate 4 CPU cores, 8 MB L3 cache and have Hyper-Threading and Turbo Boost technologies enabled. With the exception of Core i5-3470T SKU, third-generation Core i5s will have 4 CPU cores, 6 MB L3 cache, Turbo Boost, but will lack Hyper-Threading feature. Core i5-3470T will be the only Core i5-branded chip with two Hyper-Threaded cores and 3 MB of last level cache. The slide, posted in corescn forum, also reveals processors' graphics options and support for advanced on-chip technologies.

All Core i7 microprocessors and Core i5-3475S and i5-3570K will accommodate HD 4000 graphics units. Remaining Core i5 CPUs will use HD 2500 graphics. Both families will have on-chip GPU clocked at 650 MHz, which can be boosted up to 1.05 - 1.15 GHz depending on model. Other standard features of Ivy Bridge parts are dual-channel memory controller, that works with DDR3 memory with 1333 MHz and 1600 MHz data rates, and support for AES instructions. Majority of Core i5 and Core i7 SKUs also support VT-d virtualization, and Trusted Execution technology. The CPUs, that do not support these advance features, are unlocked "K" models, and several low-end Core i5 processors.

The summary of upcoming Ivy Bridge desktop chips and their features can be found in the table below:

In the body you state that the i5-3570K will accommodate the HD 4000 graphics units, and yet the table lists it next to HD 2500. Which is true?
