Can a CPU bottleneck a GPU?

I'm just curious to know. Also my friend is getting a PC with 2 xeon (4 core) not exactly sure which ones though and he says that if he pairs them up with a 650 it would fry, the GPU that is. I'm just curious... Thanks in advance!

  1. no a xeon quad-core shouldn't bottleneck any Graphics cards!.
  2. Yes, actually. Almost all GPU's are in one way or another bottlenecked by the CPU... though for most cards (particularly the Nvidia ones) the difference between an i7 and an old Phenom II is negligible, unless you turn the settings down to the point where the GPU isn't the limiting factor... in which case, you're wasting a lot of GPU.

    Xeon processors, however, are NOT designed for gaming. They should have the memory access and wot to keep the GPU fed, but it will likely struggle with the game logic itself, meaning that many games, particularly CPU-bound physics in games, will not run at a reasonable speed.

    CPU + GPU will never be frying each other. Damaging comes from PSU and motherboard.
    Bottleneck rarely happens, unless the build consists of a $50 CPU and a $200 GPU or similar ratio.
  4. yea getting a better gpu helps more.
  5. What is bottlenecking?

    It is a concept by where one part cannot keep up with another. A slow GPU that can't keep up with a highend i7. Or a crap CPU, that can't keep up with a killer GPU.

    There is no 'frying' involved. The slow part does not tell the good part "Hey dude, slow down, I can't keep up"
    It just doesn't do it.

    If one part is running at 100%, that is the 'bottle neck'. It is simply too slow to keep up, and drags the rest of the system down.
  6. +1 for that answer.
  7. I have a AMD FX-6300 Vishera 6-Core 3.5GHz (4.1GHz Turbo) and an ASUS R7260X-OC-2GD5 Radeon R7 260X 2GB. I was wondering if this would bottleneck because I play LoL and WoW on a daily basis and have been experiencing fps spikes ranging from 100 fps down to 15 fps and back up to 100 fps about every 30 seconds.
