More Details on Ivy Bridge Models "S" and "T" Emerge
With the The First Intel Ivy Bridge CPU Clock Speeds and More story from earlier this week, we caught some of the early details of the first Ivy Bridge chips, which is set to release in April 2012. Now, with some more leaked information from Chinese site Corecn, via German site ComputerBase, we find out more information on S and T model numbers.
The table provides a full listing of remaining eight upcoming models, including model number, base frequency, cache size, cores/threads, memory speed, turbo boost speeds, Intel HD graphics, frequency / dynamic frequency and TDP ratings. It appears that Ivy Bridge will have similar clock speeds to current generation Sandy Bridge CPUs, just with a lower TDP based on Intel's transition to 22 nm from 32 nm transistor design.
| Processor | Base Frequency (GHz) | Total Cache (MB) | Cores / Threads | Memory Speed Support (DDR3) | Turbo Boost max single core (GHz) | Intel HD Graphics | Frequency / Dynamic Frequency (MHz) | TDP (W) |
|---|---|---|---|---|---|---|---|---|
| Core i7-3770S | 3.10 | 8 | 4 / 8 | 1600, 1333 | 3.90 | 4000 | 650/1150 | 65 |
| Core i7-3770T | 2.50 | 8 | 4 / 8 | 1600, 1333 | 3.70 | 4000 | 650/1150 | 45 |

| Core i5-3470T | 2.90 | 3 | 2 / 4 | 1600, 1333 | 3.60 | 2500 | 650/1100 | 35 |
| Core i5-3450S | 2.80 | 6 | 4 / 4 | 1600, 1333 | 3.50 | 2500 | 650/1100 | 65 |
| Core i5-3330S | 2.70 | 6 | 4 / 4 | 1600, 1333 | 3.20 | 2500 | 650/1050 | 65 |
S - Performance-optimized (low power with 65W TDP), T – Power-optimized (ultra low power with 35-45W TDP)
Features shared by all the above mentioned Ivy Bridge CPUs are a 2-channel integrated memory controller; and all but the Core i5-3450S and i5-3330S have Intel's SIPP 2012, vPro 2012, VT-d, TXT, and AES-NI support.
