A Taiwanese overclocker tells us what the Core i7-3770K ES is capable of

With three more months to go until Intel makes official its first Ivy Bridge processors, a Taiwanese overclocker has entered into the possession of an engineering sample Core i7-3770K CPU, which he put through all sort of tests to reveal a bit more about this chip and its overclocking potential.

The tests run by TOPPC covered both the stock and overclocked performance of the Ivy Bridge CPU and while no exact numbers were specified it seems like, on average, the ES i7-3770K was 10% faster than the current Core i7-2600K.

Overclocking wise, the chip also had a similar performance with that of its Sandy Bridge counterparts, the highest frequency achieved with all cores active being set at 4.8GHz.

TOPPC expects these results to improve when the CPU hits retail, with 5GHz being possible with all cores active, as Lenzfire reports.

Despite the not so impressive overclocking frequency achieved, the Core i7-3770K does allow for higher DDR3 speeds to be achieved as the maximum available memory option is now 2800MHz.

The Core i7-3770K will include four computing cores with Hyper-Threading support running at a base frequency of 3.5GHz, and also support Intel’s Turbo Boost technology which can increase its operating speed to 3.9GHz when not all cores are loaded.

Much like the current Sandy Bridge-based Core i7 parts, the chip will also sport 8MB of shared L3 cache, but its integrated GPU has been updated to the new HD 4000 which packs 30% more EUs.

The TDP of the processor was also modified as the new 22nm Tri-Gate process technology used for Ivy Bridge helps decrease the power consumption of the CPU.

The end result is a chip that works at the same frequencies as the Core i7-2700K and sports a faster graphics core, but has a 19% lower TDP (77W vs 95W).

Just like all the other K-series processors launched by Intel until now, the Core i7-3770K also features an unlocked multiplier which means overclockers will be able to push its operating frequencies further than Intel's specifications. According to Taiwan PC makers, Intel’s Ivy Bridge processor will debut on April 8.
