4770k vs 4790k?

Im building my pc and I dont know if i should wait for 4790k or buy 4770k right now. I have ordered asrock extreme4 z97 mobo(what do you think about it?) so i have to go for intel cpu.

Whats the main difference between those two cpus? Does anyone have some news about the price of devils canyon?

  1. i have seen the 4790k overclocked to 6.4 ghz, and with air cooling you should be able to hit 5.4, but other than the overclocking ability, there isnt that much performance increase.
  2. ive heard its coming out on the 2nd of July. is it true?
  3. well, it was supposed to come out jun 2nd, but was pushed another month. idk if it will or not.
  4. do you think there will be a big difference between them while gaming and light/average editing?
  5. not for gaming or average editing, but for heavy encoding/editing, yes.
  6. *WARNING*

    The BIOS update to support the i7-4790K just came out four days ago so your board doesn't support the new CPU yet.

    I don't think you can flash that motherboard without a CPU, so I think you should just get the i7-4770K unless you can get a shop to flash the board cheaply for you

  8. What motherboard do you mean photonboy?

    The one you said, this one: http://www.asrock.com/mb/Intel/Z97%20Extreme4/?cat=Specifications

    If you look at the BIOS update section it lists the latest update on 06-04-2014 (four days ago) supporting the new CPU's.

    Since you just ordered it perhaps it will have the latest BIOS though I doubt it.
  10. of course, my fault. too much to drink. So that means i cant get devils canyon cpu on it? i ordered it yesterday on the 7th of june.

    I believe you need a CPU that the BIOS presently supports so if the BIOS is older than the latest (v1.30) it won't work.

    Asus has a "Bios Flashback" capability which is awesome and works without a CPU.

    You can alternatively get the ROM chips replaced or swapped or just have the entire board flashed at a shop. I assume it would cost at least $25.

    *You can probably find out your BIOS version based on the motherboard serial number through Asrock and see if it supports the new CPU already.
  12. so basically ive made a mistake by ordering mobo now?
  13. eh, maybe. if you have any friends with any haswell chip, ask to borrow it to update the bios :P
  14. Im still hoping that ive managed to order it just on time when the updaed the bios. i thought 06-04 is 6th of april but then z97 mobos came out in may.

    It's the 4th of June if you look at the other dates.

    I recommend getting the i7-4790K, and while you wait for it investigate your options for getting it to work:

    1) Contact Asrock with the serial number to see if BIOS v1.03 is on the board.

    2) Contact some computer shops to see if they can flash the motherboard, and if so how much.

    3) Contact Asrock and/or a shop to see if you can just swap the BIOS ROM chips (they are removable by hand) to the ones with the latest BIOS.

    Unless a shop has the exact same motherboard, you probably would have to take your motherboard in to the shop. I'm unsure if Asrock can send you the BIOS ROM chips (v1.03 or newer) or have a better idea than I've mentioned.
  16. Thanks alot photonboy. Im gonna call the shop first. I should get my motherboard after the weekend. If the motherboards got older version of bios ill try to find a way to upgrade it. if its going to be to complicated or too expensive to do it i will just go with 4770k which is still a great cpu. If everything will go as planned then 4790k it is. thanks again :)
