Core i7 3770k Review & Benchmarks
Manufacturer: Intel Corporation
Product Name: Desktop Processor
Model Number: Core i7-3770K
Price: $319 (Amazon.com)
Barely a year after the introduction of its immensely popular Sandy Bridge CPUs, Intel brings us Ivy Bridge. It's been a busy 15 months for Intel, with the introduction of no fewer than three chipset families (P67, Z68, and Z77, and many variants thereof) and three processor families (Sandy Bridge, Sandy Bridge Extreme, and Ivy Bridge).
As it has for the past several years, Intel's sticking to their "tick-tock" processor release cycle. At roughly yearly intervals, Intel will introduced either an entire new processor architecture ("tock") or a refinement thereof ("tick"). Sandy Bridge was the tock, and Ivy Bridge is the tick. The "tick" processors are usually minor upgrades in terms of capability. For Ivy Bridge, we have the power and heat advantages of Intel's new 22nm process (as compared to Sandy Bridge's 32nm), and the improved efficiency afforded by their low-leakage "3D" transistors.

what we all want to know is how the performance and features
of this new CPU compare with the Sandy Bridge line. To determine this
I'll be testing the Ivy Bridge Core i7-3770K CPU against a Sandy Bridge
Core i7-2600K.
The 22nm process enables Intel to drop the TDP from the 2600K's 95 watts down to 77 watts, a substantial reduction. The Intel Graphics HD 4000 iGPU now has 16 "graphics execution units", up from 12 in the 2600K, but Intel says the performance should be substantially improved over that of the HD 3000. If you're a corporate IT type, you'll be interested in the i7-3770 and i5-3550, which support Intel VPro Technology, a suite of hardware security features. All new Ivy Bridge desktop CPUs have 16 PCI Express Gen 3 lanes, which provide twice the bandwidth per lane of the PCI Express Gen 2 lanes used on Sandy Bridge CPUs.
Since the Ivy Bridge desktop CPUs use the same LGA1155 package as Sandy Bridge, the chips look physically identical. Unless you read the model number you won't know which one you've got.
As far as CPU performance, Ivy Bridge represents something of a stalling.
This is still a very fast CPU. It's just not much quicker than the processor it replaces. It's also not dramatically more power efficient and doesn't overclock any better.
Graphics aside, it's not a significant step forward.
Ivy Bridge is a quick chip but not enough to replace i7 2700k,2600k.

It's hard to imagine any desktop PC user ever needing more performance than the new Intel Core i7 3770K .
On a per-core level, there isn't a faster processor available. And with four cores and eight threads, there's multi-threaded performance to burn.
The new HD Graphics 4000 core is a big step forward as well.
