Intel Core i7 4790 vs 4770K

older Released May, 2014

Reasons to buy the Intel Core i7 4790

	Supports trusted computing Yes		Higher turbo clock speed 4 GHz
	Much better cinebench r10 32Bit 1-core score 7,994		Slightly higher clock speed 3.6 GHz

Of course there's also the fact that it's got a base clock of 4GHz which is also nice.

I'm going with the 4790 because it's cheaper(99 dollars right now! 249.99 at micro center vs 348.99 at superbiiz), better performance per watt, and I am not going to be overclocking or if I do then it will be a mild overclock.

Salt Turth (05:58 AM, March 8, 2015)

my ass

Tom Liu (01:22 PM, February 8, 2015)

Overclock the 4770k，beat the 4790 at once

dsftrdst (04:51 PM, August 23, 2014)

I prefer wait for ddr4

panther063 (10:05 AM, July 18, 2014)

The 4770 is only better if you plan on overclocking, which in my opinion is totally unnecessary using modern systems.

panther063 (10:04 AM, July 18, 2014)

Clearly false advertising, the sites address states 4790X LGA 2011, but when you go to the item, it clearly shows a normal 4790 LGA 1150 in it's specs.

mkosi35 (09:54 AM, June 29, 2014)

i thin better thermal solution is biggest improvement...... and bit higher closk speed.....

Guest (11:58 AM, June 9, 2014)

nothing really, new generation APU is where its at, smaller and stronger builds

bakchh johnx (08:55 PM, May 28, 2014)

Those are fakes, there is no such thing as the 4790X. However, the 4790 does exist and the 4790K is coming really soon.

Neelmay (01:11 AM, May 22, 2014)

Right now it's cheaper on amazon then the 4770k

AaronRhysD (04:03 PM, May 21, 2014)

The 4790 is a locked 4770K with a 0.1 Ghz bump running in Socket 1150. The 4820K does run on socket 2011 as you say but falls short when benched against a 4770K on stock clocks in general. Quad channel RAM gives it double the RAM bandwidth though so, if you wanted to overclock it, it would be advantageous over the 4770K.

Mitch (01:56 PM, May 21, 2014)

The 4820 and 4790 both use a different socket motherboard (Socket 2011) which is generally more expensive than a 1150 Motherboard.

Tyler (11:25 AM, May 18, 2014)

I am new to the process of building computers. Why does everyone prefer the 4770 over the higher modes like the 4820 and 4790? Both the 4820 and 4790 have generally better looking specs and are about the same price. Everywhere I look though everyone say they prefer the 4770.

Memory Type "DDR3-1333" is also accepted, revise it! http://ark.intel.com/products/80806/Intel-Core-i7-4790-Processor-8M-Cache-up-to-4_00-GHz

Dr.Madhav (05:52 PM, May 14, 2014)

I think I'll go for this one over 4770K.

Mike (02:26 AM, May 14, 2014)

It would be nice if the 4790 was 190. Proper link please.

Mokie (04:59 PM, May 13, 2014)

I thought the 4790 was an extreme series, a 4790X, which is just as unlocked and overclockable as the K version? Every online store I've looked through shows as 4790X and unlocked.. I'm more interested in x99 myself.. I was so close to pulling the trigger on a 4930K, but x99 mobo's won't be backwards compatible and I'd have no room for future improvement. Lucky z97 people..

smaller die and sata express i think
