Intel Ivy Bridge Leak

The Ivy Bridge family of processors are scheduled to be released starting in April 2012. The first batch of desktop processors has been completely exposed, including the exact model name, complete specifications, with a total of 18 models of as many as belong to Core i7 , Core i5 two sub-series.

Ivy Bridge can be said that an enhanced version of Sandy Bridge’s technology, 32nm evolution of 22nm, architecture has also been fine-tuning, but overall little change. This first batch of products can be divided into four parts, from low to high in order of: i5-3300, i5-3400, i5-3500, i7-3700.

Low end Core i3 sub-series will be launched in the Q2 2012, Pentium models are arranged in Q3 2012 with the Celeron brand being discontinued as it would seem.

Ivy Bridge the first batch of 18 models of specifications glance

IVB Core i5 has 14 models, in addition to Core i5-3470T than all four cores and four threads, the original frequency of 2.3-3.4GHz, Turbo Boost speed up the highest frequency of 3.2-3.8GHz, three cache 6MB, thermal design power side with suffix T are 45W, S are 65W, K or no suffix is 77W.

Core i5-3470T is special in that it’s dual core with four logical threads, L3 cache is halved to 3MB, carrying a 35W TDP, and carries 2.9GHz clock with turbo peaking at 3.6GHz.

IVB Core i7 only four models, the Core i7-3770 and the four variants, are quad-core eight thread, the original frequency of 2.5-3.5GHz, the frequency 3.7/3.9GHz two speed grades (still do not want to touch the 4GHz) L3 cache is full 8MB, thermal design power is divided into four categories according to different suffix 45/65/77W.

And now the same, Core i5-3570K, Core i7-3770K is an open multiplier.

Graphics core areas, Core i7-3700 series, Core i5-3570K, Core i5-3475S are integrated HD Graphics 4000, with sixteen execution units, and other fully integrated HD Graphics 2500, eight suspected graphics unit, just between the current between the HD Graphics 2000/3000.

What speed, unified set at the reference frequency 650MHz, acceleration frequency Core i5-3330S only 1050MHz, other Core i5-3300/3400 series is 1100MHz, Core i5-3500/i7-3700 series were all 1150MHz, not very different.

Incidentally, VT-d virtualization technology and equipment, AES-NI instruction set. Universal access to the latter, the former is missing in the Core i5-3300S/3300/3450S/3450 four lowest-end model and Core i5-3570K/i7-3770K two models.

Also in memory, all unified support dual channel DDR3-1600/1333.
