Ivy Bridge-E, it's the all updated 22nm K+ metal gate core technology "enhanced" slash "enthusiast" version of what pretty much is similar to the Sandy Bridge-E architecture, you'll see few new features added and even some others stripped away. Simply put, you take all the good ingredients from Sandy Bridge-E and place it on a smaller die. Compared to the regular mainstream Sandy Bridge (and Ivy Bridge) processors add two more cores, a slightly increased L3 cache and add a pinch of quad-channel memory.
There is one exception to the rule, one Core i7 Sandy Bridge-E CPU will remain a quad-core processor, not six cores. There's also something else missing, though we doubt a little that you'd miss it in this enthusiast grade segment. Both Ivy- and Sandy Bridge-E do not have an on-die graphics processor built into the architecture. No biggy as we expect you to use a dedicated GPU anyways, but for the transcoding freaks that are dependant on QuickSync as a feature, you might need to reconsider this processor purchase.
Above you can see the naked die of Ivy Bridge-E. In this first wave of Ivy Bridge-E processors Intel is going to release three Ivy Bridge-E class SKUs, namely the Core i7-4960X, the Core i7-4930K, and the Core i7-4820. Each will have different clock frequencies and a slightly changed L3 cache.
Core i7 4820K
The Core i7-4820 is a quad core processor, the other two are six-core processors. The processor will have six cores (2 deactivated), turbo boost 2.0, Hyper-Threading, up-to 15MB of L3 smart cache, 4 channels of DDR3 1866, AVX, AES SSE 4.1 and 4.2 instruction set. This very simply means that two out of the six cores are disabled. The Core i7-4820 will be prices slightly cheaper then the Core i7 4770K actually, the MSRP is set at 310 USD, meaning that the price will drop under 300 USD real soon- real fast.
Below, an overview of the main specs per processor.
From a naming point of view is that Intel chooses three different suffixes for the processors, we have an X model, a K model and a "normal" model. A little confusing, but it does make some sense:
The X suffix is Intels Extreme Edition processors, this means the top-of-the-line unlocked processors.
The K suffix denotes a slightly lower end processor yet with its multiplier unlocked.
And the normal editions are pretty much mainstream without any enthusiast grade overclock options, meaning a locked multiplier.
The flagship Intel Ivy Bridge-E CPU is the Core i7-4960X packed with 6 cores and 12 threads and would feature a core clock of 3.6 GHz base and 4.0 GHz Turbo boost with 15 MB of L3 cache. The Extreme Edition CPU costs a whopping $1000 and boast a 130W TDP. Cache wise the L1 and L2 caches are 100% similar to Ivy Bridge:
32KB data and a 32KB instruction L1 cache per physical core.
256KB L2 cache per core.
The L3 cache then, The Core i7-4820K tested in this article has 10MB of L3 cache, meaning 2.5 MB per core (it's a single block of cache as it's shared).
