The high price of the i7-5775C is quite obvious sitting very close to the i7-5820K HEDT part price-wise and costs a lot more than the more powerful i7-4790K Devil’s Canyon processor. For enthusiasts running a discrete graphics card, it is obvious that the i7-5775C is not aimed directly for them. The eDRAM integration defintely adds to the price but looking at the Intel pricing trend however, this is not really surprising as unlike AMD, price cuts is not a valid strategy in staying relevant for Intel.

The objective in this article is to see how well the new i7-5775C performs over the original flagship i7-4770K while looking at how much graphics power the new Iris Pro technology brings compared to AMD’s R7 APU, the current desktop standard for integrated graphics performance. An A10-7870K and i7-4790K are also available in retail but considering these are higher clocked variants, information on how these will perform can easily be extrapolated from the results of comparing the i7-5775C to the A10-7850K and i7-4770K.

  1. Wow man what can I say. Excellent review, I am a bit disappointed that the 5775C does not have at least the same frequency of the 4790K, I believe for people that have machine that do not use a graphics card, this might be a better choice because of the Intel graphics. Plus the fact that the 5770C is LGA and not BGA is also a plus. My understanding is that with BGA you have to change out the whole motherboard also. So for people that are using a previous 1150 build to upgrade, this would make the chip not worth the trouble. I would love to see what GPU the new 6200 graphics stack up against. Again Ron, very informative and excellent review.

  2. Thank you very much Alan. Yeah, although looking at it from Intel’s perspective this is a win for them. This move will push more of the enthusiast crowd to the HEDT/Intel Extreme platform while increasing the userbase of the mainstream desktop platform for those that want a capable integrated IGP with a more powerful CPU and those who want a more powerful option than what AMD offers.

  3. people who are going to buy an i7 problably wont be using the integrated graphics and the point of AMDs apus where never to be high end they gave decent gaming performance at 720p this are entirely different consumers they guy that thinking of buying an APU is not going to buy an intel processor

  4. I am sorry for AMD they are 1 or 2 steps behind from Intel it seems
    Someone that wants performance will surely choose this processor over anything that AMD offers right now
