It’s the time of the year – less than six months from the launch of Ivy Bridge – and more juicy details have leaked. Among these we find clock frequencies, new graphics circuits, but what is extra interesting is that Intel has managed to cross over almost entirely to quad-core processors.

The details on Ivy Bridge has surfaced with lots of juicy details. Ivy Bridge will be Intel’s first product made with the new 22nm process sporting Tri-gate transistors, and comes with a new graphics circuit and lower TDP. Intel will also be focusing more on quad-core models, since only one of 18 models sport only two cores.

The new graphics circuit comes in two versions where GT1 is HD 2500 and GT2 is HD 4000. The names implies HD 2500 will perform in between the current HD 2000 and HD 3000 models, while HD 4000 should do better. All graphics circuits are clocked at 650 MHz and has a Turbo mode at 1.1 to 1.15 GHz depending on model – a seemingly small difference. The graphics will also support several new GPGPU functions, DirectX 11 and better IPC than before, which means it doesn’t have to raise clock frequencies much to get better performance.

Core i5-3330S 4 4 2.7 GHz 3.2 GHz 6 MB HD 2500 65W

Core i5-3475S 4 4 2,9 GHz 3.6 GHz 6 MB HD 4000 65W
Core i5-3550 4 4 3.3 GHz 3.7 GHz 6 MB HD 2500 77W
Core i5-3550S 4 4 3.0 GHz 3.7 GHz 6 MB HD 2500 65W
Core i5-3570 4 4 3.4 GHz 3.8 GHz 6 MB HD 2500 77W
Core i5-3570K 4 4 3.4 GHz 3.8 GHz 6 MB HD 4000 77W
Core i5-3570S 4 4 3.1 GHz 3.8 GHz 6 MB HD 2500 65W
Core i5-3570T 4 4 2.3 GHz 3.3 GHz 6 MB HD 2500 45W
Core i7-3770 4 8 3.4 GHz 3.9 GHz 8 MB HD 4000 77W
Core i7-3770K 4 8 3.5 GHz 3.9 GHz 8 MB HD 4000 77W
Core i7-3770S 4 8 3.1 GHz 3.9 GHz 8 MB HD 4000 65W
Core i7-3770T 4 8 2.5 GHz 3.7 GHz 8 MB HD 4000 45W

We find one processor at 35W TDP, Core i5-3470T, clocked at 2.9/3.6 GHz, with 3 MB L3 cache and HD 2500 graphics. This is also the only dual-core processor in the list, and considering Ivy Bridge is expected to be a relatively small circuit it is really not that weird Intel has chosen to do this. Other models are listed at 45, 65 and 77W TDP, which will be the max for Ivy Bridge. All models support DDR3-1333 and DDR3-1600.

We get two models geared for enthusiasts and overclockers. Core i5-3570K gets four cores clocked at 3.4/3.8 GHz, 6 MB L3 cache, HD 4000 graphics, 77W TDP and unlocked multiplier. Core i7-3770K gets four cores with Hyper-threading clocked at 3.5/3.9 GHz, 8 MB L3 cache, HD 4000 graphics, 77W TDP and is also unlocked. The obvious parallel is Core i5-2500K and Core i7-2700K, with exact same clock frequencies but new graphics and lower TDP.

Intel has made other changes to the architecture that will boost performance with ~6%, but overall we were hoping for higher clock frequencies. We can only assume that Intel doesn’t see a need for this and instead choose to keep energy consumption down instead, but we can always hope that Ivy Bridge has higher overclocking potential than Sandy Bridge.

We can also presume that this is far from all models coming, but that there is also a Core i3 and Pentium series that will come later. These series might include more dual-core models. If the information on Ivy Bridge getting a BCLK multiplier like Sandy Bridge-E it means you don’t need to get a more expensive, unlocked model for overclocking, but at limited capacity.
