Sorry if this has been posted already but I'd like to get my own answer.

I'm looking into buying an i7 (Mainly for gaming and video editing)

How is the 4820K compared to the 4770K?

The 4820K is the only one to have the right amount of SATA ports on the motherboard brand I want so I'm mainly considering that.

http://www.amazon.co.uk/ASRock-X79-Extreme9-Motherboard-CrossFireX/dp/B006NZONOA/ref=sr_1_1?ie=UTF8&qid=1389841665&sr=8-1&keywords=asrock+2011

If I wanted that many SATA ports on an Asrock board with the 4770K i'd have to spend £400ish on the motherboard alone...

So my questions:

1) What is the best CPU for overclocking?

2) Does the 4820K have solder (Like my 2500K) or thermal paste like the 4770K?

3) Is there actually much of a difference between the two CPU's?

Price/performance you can't beat the 4770K.

4770K vs 4820K
  • Dual vs Quad channel memory
  • TIM vs Soldered
  • 8x vs 16x PCIE 3.0 when running 2 cards (16 vs 40 PCIE lanes)
  • When running 3 cards 4770K @ 8/4/4x vs 4820K @ 16/16/8x
  • More native SATA ports on 4820K
  • 3.5ghz vs 3.7ghz
  • Built in GPU vs CPU only
Overclocking wise they are pretty equal, and its more up to the chip lottery than anything else.
So in the end, do you want more/better features, or do you want to save money.

both of them are confirmed EOL maybe wait and see what z97 has to offer. atleast then you can bump up to broadwell at a later date.

EDIT I thought maybe I should actually answer the question presented. I would go 4770k over a 4820k just based on price now if thats just a place holder for a 4930k then absolutely get the 4820k I just find that the performance is similar so why spend the extra money (between the cpu and motherboards)

However the 4820K has more native SATA ports, soldered, quad channel memory and (compared to dual) more PCIE channels meaning you can run two cards at 16x PCIE 3.0.

The thing is, the 4820K is literally only £1 more on Amazon and it'd be cheaper getting a board with the amount of SATA's I need. But people say the 4770K is better... So I'm really confused which one to go for.

How much of a temperature difference do you think there would be using a h100i or a custom loop?

With overclocking I understand that it's mainly the lottery that decides how far the chip OC's but I was thinking the 4820K would go further due to less heat meaning slightly better performance (Let's say a 4770k @ 4.6GHz VS a 4820K at 4.8ghz?)

Which one would you go for in my situation?

I edited my original post for better clarity. Check it out.

Overall might be a little better overclocking results in general on 4770K, but not by much.
The 4820K will run a fair bit cooler most likely, so you could get better results from that.
A custom loop will crush any all in one loop or air cooler, so if you got the money/interest I would highly recommend a proper custom loop with at least a 360 radiator.

Personally in your case, I would go for the 4820K.

Cheers for the original post, quite useful!

What do you think about waiting for Haswell-E or Broadwell i7's and keeping my 2500K and putting my money into a proper water loop for now?
I'd want an i7 between Q4 2014 and Q1 2015 though.

I was planning a 360MM and 120MM radiator for the CPU and 7990.

My pleasure!

Well it's not so long before it comes out, so you could wait and see how they perform. But again, technology is always improving so no matter if you buy the latest and greatest you can be pretty sure it will not be the greatest just after some months or a year. So one must decide when to stop waiting for new hardware to arrive, as it will always be something better around the corner.
Haswell-E is rumored for a Q3 release, Haswell refresh coming in May, Devil's Canyon Q3 and Broadwell Q4 or Q1 2015.

That should be a pretty good setup, just pick up some good radiators and fans.

I went with the 4820k simply because i was able to get 24 Gb (4gb x 6) of kingston ram for 120 bucks at Frys-Which is useless on any z87 because they're limited to 4 DIMMS. After having both systems set up and running, I am happier with the 4820. the x79 chipset owns the z87 i was using. Unless you're all about getting the max overclock meaning, to the point of competing, I'd go with x79 simply for quad channel memory speeds. Plus i have mine overclocked to 4.7 aircooledwith a temp of 42C. x79 is just better

1. In what way is the X79 owning the Z87? Did you benchmark both chipsets? Why don't you post your benchmarks and methodology here?

2. What is the use for higher memory speeds?

ANANDTECH state that any RAM speed above 1866 CL8 is pretty much useless for gaming as it does not afford any kind of improvement. I really hope that you are not gaming b/c if you do, you sound like a tool to me.

They are both very similar - I'd personally prefer a 4770K to be honest though. They both perform pretty similar so either one is good though sometimes either one coming on top:

http://www.guru3d.com/articles_pages/core_i7_4820k_processor_review,14.html

If you want that many SATA ports you could look into PCI/PCI-E SATA cards and save money by getting a cheaper motherboard. How many drives are you planning to connect?

But to answer your questions:

1) The 4820K is probally better since it's on the ethustast platform and is soldered. The Haswells overclockablity is pretty unpredictable so it's a gamble.

2) 4820K is soldered

3) No - not much at all. 4770K is slightly faster and use less power. Socket 2011 chipsets have more features than the Z87 though.

Hey man easy with the 'tool' comment. I was referring to the fact that my 6 sticks can run in quad channel mode instead of dual channel mode on the z87 mobo. Most sites/articles post that it's not possible to get quad channel with 6 sticks on an x79 but it is if you put them in the right DIMMs. I just like the lower heat that I'm getting overclocking to 4.7 and using air cooling. I was only able to get to 4.5 with the 4770k I had which isn't bad, but the temps were about 10-15 degree Celsius higher.

Drop the attitude already.

While its not owning, it is no doubt better with the plethora of features you get with it. Also you got support for 6core if he wants to upgrade later on.
So you mean that because of one article, high speed memory is useless? It is not......
There are a lot of uses to higher speed memory, while the speed increase may not be worth it to you, it is for many of us here on OCN. Same goes for quad channel memory. What uses you can research yourself.

When it comes to games, some actually do take advantage of higher speed memory, like the recent Battlefield 4.

Here's a picture from Corsair to prove it:
