Intel core i7 4770k VS Intel Core i7 4820k? What's Better?

Shark Dentist · Jul 4, 2014

Hey folks!
I'm about to purchase a new CPU and have 2 in mind. The Intel Core i7 4770k -http://www.amazon.co.uk/gp/product/B00CO8TBQ0/ref=s9_simh_gw_p147_d1_i2?pf_rd_m=A3P5ROKL5A1OLE&pf_rd_s=center-2&pf_rd_r=1RWSHN78JMCE78PXRXRG&pf_rd_t=101&pf_rd_p=455344027&pf_rd_i=468294

OR

The Intel Core i7 4820k - http://www.amazon.co.uk/Intel-Unlocked-Unleashed-Hyper-Threading-Technology/dp/B00EONU086/ref=sr_1_1?s=computers&ie=UTF8&qid=1404486321&sr=1-1&keywords=intel+core+i7+4820k

Which one is better?

Thanks in advance!

Do you already have a motherboard? The 4820 is a socket 2011 chip (technically an Ivy Bridge / 3rd gen chip) while the 4770 is socket 1150

Get the 4790k, it's a better version of the 4770k

But check if your motherboard is comparible.

SchizTech :

Yeah I already have the motherboard (not sure what model exactly) but the CPU I'm using now is a AMD FX-4100.

As to the CPUs, the 4770K is a generation newer, though the generational gap is relatively small here. It's a bit more efficient. The 4820 is an "enthusiast" version of 3rd gen chip, offering more PCIE and memory lanes. Socket 2011 offers higher core chips too, the extreme 6 core chips. Generally the extra RAM and PCIe on the higher end socket are only needed for high end workstation kind of uses. For gaming the standard socket and chipsets are fine.

You'll need a z97 or z87 motherboard. Your amd motherboard is amd

SchizTech · Jul 4, 2014

Shark Dentist :

Well that's an AMD board, so you can't use either chip. Intel and AMD CPUs are not cross compatible with motherboards. You need to look for a higher end AM3+ AMD CPU

SchizTech · Jul 4, 2014

The model number for your board should be printed somewhere on the board (usually around the PCI express slots). If you can find that I'll bring up the CPU compatibility list.

SchizTech :

So I'm going to have to buy a new motherboard aswell? Ah shit! :\ How much would a compatible motherboard for the i7s I listed above cost?

SchizTech · Jul 4, 2014

An 1150 socket board is the more economical choice in general (socket 2011 boards tend to be more expensive). A compatible board for the 4770K can be found among here:

or

pre-sorted between 50 to 100 GBP. The Z97 (second set) allow overclocking, otherwise the sets are pretty similar.

Does the first allow overclocking,no?

SchizTech · Jul 4, 2014

The Z97 is designed for overclocking, if you wish to OC you should choose one of those

Shark Dentist · Jul 4, 2014

I've never actually overclocked before,what's the advantage?

SchizTech · Jul 4, 2014

What are you going to use this system for? Overclocking runs the CPU at a higher frequency than it's set to run at the factory, making it faster (but also hotter). You'd only notice the difference when you push the CPU, for example in games, if your video card is fast enough to show the difference. Due to the extra heat it's also advisable to use a higher-end aftermarket CPU cooler. Depending on how far you go with the OC it may shorten the life of the chip.

DubbleClick · Jul 4, 2014

There's some "cheap" z97 boards out there, I got mine for a bit less than 100€ (little less than 80£).
Generally, just having the possibility to oc isn't bad. I kept my old q6600 running at stock for quite a few years, until it came to the point it's power wasn't sufficient for lastest applications anymore. Overclocked it and was satisfied with its performance for another 2 years.

Shark Dentist · Jul 5, 2014

SchizTech :

Yeah a few extra quid for the option to overclock doesn't seem too bad... So if I get the motherboard and CPU I'm good to go,no other compatible parts I need? Will my AMD GPU be compatible with the z97 board.

Here's my specs just incase:

CPU: AMD FX-4100 Quad core 3.6GHz
GPU: AMD Radeon HD 7800 series (not sure what model exactly) 2GB
RAM: 16gb ram
POWER SUPPLY: 500w

And a quick side question.. What one of my PC parts do you think needs the most upgrade?

SchizTech · Jul 5, 2014

Shark Dentist :

As I said above, AMD CPUs only work with AMD motherboards, Intel chips only with Intel boards. You'd have to replace them together. The rest of your specs are pretty good (not absolute top of the line, but a very respectable system). With a new CPU and board it should work (you'll probably have to reinstall Windows) though if you do OC it'd be wise to replace the stock CPU cooler with a better aftermarket fan. Those aren't generally too expensive compared to the CPU and board itself (can't give proper estimate since I'm not familiar with how they're priced in the UK)
