Jeremy posted earlier that Guru3D managed to spot a list of Ivy Bridge processors on Intel’s site before getting taken down; however, they did not indicate any specific release dates. A recent article over at TechARP today did mention two dates that are allegedly going to be the launch date and release date for Intel’s latest Ivy Bridge 22nm processors.

According to the article, Intel will launch their Ivy Bridge CPUs on Friday March 23, 2012, and then the actual release date (when hardware will be available) will be April 29, 2012.

Among the new processors are Intel’s standard TDP parts at 77 Watts and low voltage parts with 65 Watt TDPs. Of the standard voltage parts, the "K" series Ivy Bridge CPUs will feature Intel’s newest HD 4000 processor graphics and unlocked multipliers. All the nitty-gritty details including clock speeds and core counts are shown in the chart below. The HD 2500 GPU will is the chip that the remaining processors use.

Model Cores / Threads Clock Speed / Turbo Boost (GHz) L3 Cache Processor Graphics TDP Launch Price ($USD)
 i7-3770K  4 / 8  3.5 / 3.9   8 MB  HD 4000  77 W  $332
 i7-3770  4 / 8  3.4 / 3.9  8 MB  HD 4000  77  W  $294
 i5-3570K  4 / 4  3.4 / 3.8  6 MB  HD 4000  77 W  $225
 i5-3570  4 / 4  3.4 / 3.8  6 MB  HD 2500  77 W  $215
 i5-3550  4 / 4  3.3 / 3.7  6 MB  HD 2500  77 W  $205
 i5-3470  4 / 4  3.2 / 3.6  6 MB  HD 2500  77 W  NA
 i5-3450  4 / 4  3.1 / 3.5  6 MB  HD 2500  77 W  $184
 i5-3330  4 / 4  3.0 / 3.2  6 MB  HD 2500  77 W  NA

 

Further, Intel’s low voltage Ivy Bridge processors on the desktop feature clock speeds ranging from 2.7 GHz to 3.1 GHz and between 2 and four cores. Of these CPUs, only the top end Intel Core i7-3770T and i7-3770S along with the Core i5-3470T processors will include Intel’s Hyper-Threading technology. Also, only the two top end low voltage parts and the Intel Core i5-3475S Ivy Bridge CPU will use Intel’s new HD 4000 processor graphics. The remaining parts will use the HD 2500 GPU. The chart below lists the current desktop lineup of low voltage parts including price, core count, and clock speeds.

Model Cores / Threads Clock Speed / Turbo Boost (GHz) L3 Cache Processor Graphics TDP Launch Price ($USD)
 i7-3770S   4 / 8  3.1 / 3.9  8 MB  HD 4000  65 W  $294
 i7-3770T  4 / 8  2.5 / 3.7  8 MB  HD 4000  65 W  $294
 i5-3570S  4 / 4  3.1 / 3.8  6 MB  HD 2500  65 W  $205
 i5-3570T  4 / 4  2.3 / 3.3  6 MB  HD 2500  65 W  $205
 i5-3550S  4 / 4  3.0 / 3.7  6 MB  HD 2500  65 W  $205
 i5-3475S  4 / 4  2.9 / 3.6  6 MB  HD 4000  65 W  NA
 i5-3470S  4 / 4  2.9 / 3.6  3 MB  HD 2500  65 W  NA
 i5-3470T  2 / 4  2.9 / 3.6  3 MB  HD 2500  65 W  $184
 i5-3450S  4 / 4  2.8 / 3.5  6 MB  HD 2500  65 W  $184
 i5-3330S  4 / 4  2.7 / 3.2  6 MB  HD 2500  65 W  NA
