Performance Real world tests of Intel Core i7 3770K
3D Mark 11 (Physics)
Core i7 3770K by Legit Reviews (Apr, 2012)Since the Intel HD 4000 Graphics supports DirectX 11 you can run 3DMark 11 on the Intel Core i7-3770K processor without the need of a discrete graphics card.
Core i7 3770K by Legit Reviews (Apr, 2012)Benchmark Results: The Intel Core i7-3770K finished in third place, which is where it has finished in most of the benchmarks with a solid score of 21293 3DMarks.
Passmark
Core i7 3770K by FASTER220 (Jul, 2012)I ran the passmark pc test cpu bench and the highest at 5200mhz I reached was 12884.4 cpu score thats close to the I-7 six core speeds.
Core i7 3770K by Legit Reviews (Apr, 2012)Benchmark Results: The CPU benchmark results in 3DMark Vantage showed the Intel Core i7-3770K coming in third place again with a score of 26646 3DMarks.
Features Key features of the Intel Core i7 3770K
clock speed
Core i7 3770K by Legit Reviews (Apr, 2012)The Intel Core i7-3770K has a base clock of 3.5GHz, but you will seldom see it at that speed.
Core i7 3770K by Legit Reviews (May, 2012)The Intel Core i7 3770K utilizes a Bclk of 100MHz, under full load the Intel Core i7 3770K uses a multiplier of x35 to achieve the final clock speed of 3.5GHz.
turbo clock speed
Core i7 3770K by Shawn-Lind (Jan, 2013)I'll probably just throttle up the turbo speed and leave the other stepping in tack.
Core i7 3770K by PCMag (Apr, 2012)And of course traditional Intel technologies, like Turbo Boost, which dynamically increases your CPU speed when you have the headroom available for it, and Hyper-Threading, which effectively doubles the number of processing threads you have at your disposal, are present as well.
L2 cache
Core i7 3770K by Legit Reviews (Apr, 2012)Intel Smart Cache: 8MB of shared cached allows faster access to your data by enabling dynamic and efficient allocation of the cache to match the needs of each core significantly reducing latency to frequently used data and improving performance.
Core i7 3770K by beckleyja (Dec, 2012)Intel Core i7-3770K Quad-Core Processor 3.5 GHz 8 MB Cache LGA processor works well in my rig.
gpu clock speed
Core i7 3770K by MarcusI got lucky with an ASUS mainboard, which uses Virtu Logix that is at least able to switch on *exe, which GPU shall be used.
Core i7 3770K by nako (Apr, 2012)If you do not have much use for the GPU, most i5 and i7 owners will have a hard time justifying the Ivy Bridge upgrade.
overclocked clock speed (air)
Core i7 3770K by Ryan-P.-Joseph--fishrule85 (May, 2012)Overclocking it is a complete joy as well, I have never overclocked a chip as easily as this one.
Core i7 3770K by Legit Reviews (Apr, 2012)We were able to overclock the Core i7-3770K up to 4.8GHz with full stability.
overclocked clock speed (water)
Core i7 3770K by MarcusAs others mentioned in various tests and benchmark, it might only take 1 minute to overclock this CPU, even in windows easily and stable.
Core i7 3770K by Jason-Mangano (Jan, 2013)Overclocking is easy and breezy placed with Asus Suite II programing.

Socket Type
Intel Core i7 3770K | Rated 60% by by Steven-LevelIt's just as fast minus 100 MHZ, but can easily be over-clocked on the Sandys a full GHZ over the stock speed as long as you have good RAM (Crucail or Gskill), and a quality aftermarket cooler.
Intel Core i7 3770K | by Legit Reviews (May, 2012)That's only 10% over the stock Bclk of 100MHz, more than likely you would have a chip that could handle around 105MHz Bclk.
Intel Core i7 3770K | Rated 100% by by FASTER220 (Jul, 2012)Update 7/24/12 I overclocked the 3770k to 4914.5 and Corsair CMT16GX3M4X2133C9 ram to 1950.6 mhz specs 47x cpu ratio, blk 104.5 and 1.385volts.
Socket
Intel Core i7 3770K | by Legit Reviews (Apr, 2012)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.
Intel Core i7 3770K | 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!
Intel Core i7 3770K | 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.
Performance
Intel Core i7 3770K | by Legit Reviews (Apr, 2012)Benchmark Results: A quick look at the single core CPU benchmark revealed that the Core i7-3770K had the highest single core performance of any processor benchmarked!
Intel Core i7 3770K | Rated 20% by by Tom-C (Sep, 2012)Meanwhile I will enjoy the unmatched performance of the certified highest performance processer in the world!
Intel Core i7 3770K | by Legit Reviews (Apr, 2012)Benchmark Results: The GPU score for the Intel Core i7-3770K is the second highest for this test platform.
Overclocking
Intel Core i7 3770K | Rated 100% by by Sawyer-David-Piwetz (Jan, 2013)The included fan is good enough by itself if you're not overclocking, but if you are, it would be wise to buy an aftermarket cooler.
Intel Core i7 3770K | Rated 100% by by MarcusIf you go for a Z77 chipset you can use the full overclocking potential and can use the integrated graphic, as well as a dedicated one.
Intel Core i7 3770K | Rated 100% by by Arctik (Nov, 2012)It is able to be overclocked really well, and is super fast without it anyways.
Multicore
Intel Core i7 3770K | Rated 100% by by Jason-Mangano (Jan, 2013)If it's not enough then obviously there is a hex-a core 2nd gen. (BEAST).
Intel Core i7 3770K | Rated 100% by by MarcusI don't really get an Idea how to use that feature yet, but it might save power or if you are using software that adresses individual cores only, you might save heat if you have the unused cores throttled down at slow speed.
Intel Core i7 3770K | Rated 80% by by Tech Radar (Apr, 2012)And yet Intel is calling it the third generation Core architecture.

vote The 3770K will beat the 3820 in performance due to the fact that is utilizes the newer Ivy Bridge architecture versus the older Sandy Bridge-E architecture.
