clock speed

Core i5 3570K3.4 GHz

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 (Apr, 2012)

Built-in Turbo boost feature clocks the 3570k up to 3.8GHz-which is a pretty decent boost and would be a good option for gamers who are uncomfortable with messing with BIOS settings to OC their CPUs.-Almost identical to the 3770K in terms of gaming performance.

I'll probably just throttle up the turbo speed and leave the other stepping in tack.

Core i7 3770K by Shawn-Lind (Jan, 2013)

HINT: To give this processor longer life instead of simply turning up the CPU multiplier up to overclock turn up the turbo multiplier so you can still take advantage of the power saving option with these Intel 3rd gen Processors.

It's fast, efficient, and most of them overclock pretty well.

Since this CPU can be overclocked fairly easily, you might want to invest in a good CPU fan.

Reviews Word on the street

	Intel Core i7 3770K		Intel Core i5 3570K
	Rated 80% Read the review (Apr, 2012) In truth, the per-core performance of Sandy Bridge was well beyond anything we expected.		Rated 80% Read the review (Apr, 2012) At first glance, you might wonder whether the Intel Core i5 3570K is actually a new chip, so similar are the headline specifications to its predecessor.

	Rated 93% by 46 users at amazon.com After running for hours the CPU temp is 104 F at 4.5 Ghz and the system is incredibly fast. Rated 100% by by Art-the-Science-Guy (Dec, 2012) I built my last computer which ran an AMD Athlon 6000 3 Ghz, overclocked to 3.8 Ghz, and even today it will play any game out there. Rated 100% by by Dale-T.-Morse (Jan, 2013) The really nice thing about this processor is that it has native support for USB 3.0, SATA III, and PCI Express 3.0 right out of the gate. Rated 100% by by T-C-H (Jul, 2012)		Rated 97% by 229 users at amazon.com This chip is amazing!!I am cooling using the H80i water by Corsair. Rated 100% by by CrunchTime--CrunchTime (Feb, 2013) Old computers could handle text with adequate speed, but photo editing takes time and videos mega-time. Rated 100% by by Ralph-Kurtzman (Nov, 2012) But with that said now I doing video editing and encoding and the 3570k still impresses when doing that. Rated 100% by by Randy.M (Dec, 2012)

	Rated 90% by 3 users at www.overclock.net Was just playing BF3 about 5 minutes ago, and the processor is now idling at 31-32C(according to PC Meter). Rated 100% by by nicksabeast (Dec, 2012) The Intel i7 3770K is a fantastic processor, I wanted to build a workstation PC for 3D graphics, but I couldn't afford a proper Intel Xeon CPU, so I opted for this instead. Rated 90% by by JWak-1 (Aug, 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). Rated 80% by by Totally-Dubbed (Oct, 2012)		Rated 90% by 3 users at www.overclock.net At 4.7GHz@1.385 Volts, I'm hitting the 90s occasionally with Prime95, and that's with a H100 in. Rated 80% by by tr4zz0id (Jun, 2012) It is very powerful, very good for overclocking and as long as you have a good cooler, the temps are alright. Rated 100% by by snipekill2445 (Nov, 2012) Pros: Faster than SB (if only by 10%), dead easy to overclock, on z77 boards the RAM is so fun to play with. Rated 80% by by tr4zz0id (Jun, 2012)

Socket Type

Best performance above AMD FX Series... and this is better than i7 3820 (LGA 2011), i7 3930k is good choice only if you have a multi-gpu configuration... 3770k is good for overall.

Benchmark Results: The x264 HD benchmark showed the Intel Core i7-3770K had very solid passes with 164.5 FPS on pass 1 and 41.7 FPS on pass 2.

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.

socket

Intel Core i7-3770K Quad-Core Processor 3.5 GHz 8 MB Cache LGA processor works well in my rig.

The Intel Core i7-3770K ran the benchmark at 3.7GHz thanks to Turbo and finished nearly 6% faster than the Intel Core i7-2700K!

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!

performance

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!

Results: The Intel Core i7-3770K processor did great in the Sandra multi-media benchmark.

Benchmark Results: The GPU score for the Intel Core i7-3770K is the second highest for this test platform.

applications

OVERALL: The 3570k is an excellent CPU for any game on the market with a great performance-to-price ratio.

These games are fairly difficult to run smoothly at very high graphics settings due in large part to incredible (but demanding) particle effects, high unit density, shadow effects and many others, but the 3570k has no problems handling Empire at max settings (assuming you have a decent GPU to boot).

This CPU will chew through any game, and I get much better performance than I ever did with the 955-the 3570k simply blows AMD out of the water.

gaming

Benchmark Results:With the discrete graphics card removed from the system we see the numbers drop big time, but the Intel Core i7-3770K still used more power at idle and during gaming than the Intel Core i7-2700K.

Virtually all gaming performance benchmarks that you will find give near identical results for the 3570k and 3770k, so I would save yourself $100 and take the 3570K over the 3770k and put that money into a better graphics card or an SSD.
