Reviews Word on the street for the Intel Core i7 3770K


8.0
And because Ivy Bridge chips like the Core i7-3770K are intended for more middle-of-the-road users, they come loaded with integrated graphics systems that can drive up to three independent displays and support HDMI 1.4a and its associated high-quality audio, in addition to InTru 3D (for stereoscopic 3D) and HD video conferencing.

8.0
It's hard to imagine any desktop PC user ever needing more performance than the new Intel Core i7 3770K serves up.

9.4
Was just playing BF3 about 5 minutes ago, and the processor is now idling at 31-32C(according to PC Meter).

What People Are Saying Give it to me straight

Socket Type

Benchmark Results: HandBrake version 0.9.5 benchmarking showed the Intel Core i7-3770K performing really well as it was even faster than the Core i7-3820.
by Legit Reviews (Apr, 2012)
Benchmark Results: The Intel Core i7-3820 finished the POV-Ray benchmark in 205.77 seconds, but that wasn't enough as the Intel Core i7-3770K finished the benchmark in 192.85 seconds!
by Legit Reviews (Apr, 2012)
Benchmark Results:The Intel Core i7-3770K scored 44.1 FPS at 1280x1024, which was roughly 45% faster than what the Intel Core i7-2700K could do on the same benchmark.

Socket

Benchmark results: Not a surprising result, overclocked the Intel Core i7 3770k had a physics score that is 23.5% faster than at default speeds.

Moving past the LGA1156 Lynnfield processors, Intel launched the LGA1155 H2 socket along with their new 'Sandy Bridge' processors.
by Legit Reviews (May, 2012)
The Ivy Bridge technology in this processor is great, however I found that when OC'ing it was extremely sensitive, and by that I mean, with 0.01v added to Vcore, temps went up experientially (this was at 1.25v @ 4.2ghz).

Performance

Benchmark Results: The GPU score for the Intel Core i7-3770K is the second highest for this test platform.
by Legit Reviews (Apr, 2012)
When we looked at the performance with our initial article it was clearly faster than the previous generation was.
by Legit Reviews (May, 2012)
Intel says that due to this design the Ivy Bridge based processors are a good two- to three-years ahead of the competitors' designs in terms of performance.
by Legit Reviews (Apr, 2012)

Overclocking

We were able to overclock the Core i7-3770K up to 4.8GHz with full stability.
by Legit Reviews (Apr, 2012)
If you're overclocking you will lose efficiency, but gain overall system performance.
by Legit Reviews (May, 2012)
If you aren't familiar with overclocking since the Intel 'Sandy Bridge' launch in January of 2011, it's been a trip.

Multicore

In truth, the per-core performance of Sandy Bridge was well beyond anything we expected.
by Tech Radar (Apr, 2012)
And yet Intel is calling it the third generation Core architecture.

We then averaged the temperatures of the four cores and finally rounded to the nearest whole number to keep things simple.
