Bottleneck: A phenomenon where the capacity of an entire system is limited by lowest-capacity part of such system
Introduction:
Hi,
I heard my intel e6600 could overclock easily to 4GHz on air, so I went on and bought a good cooler. After many attempts and reads, I concluded that unfortunately my old motherboard isn’t a good overclocker. So again I went on and found a new motherboard and successfully got it stable at 3.6 GHz without compromising it with too high voltage. I found out my old board max possible fsb was around 1200(300*4). Figured out I’ll buy a processor with lower fsb than the e6600 to fit in, ended up with intel e2200, been able to overclock it to 3.3GHz stable.

Worries:
While messing around I noticed the e2200 overclocked is not as fast as the e6600 at stock speed in different games with the same rig. During the process I ended up with a question about bottleneck: how does it work exactly? What causes a bottleneck? I have been surfing around to understand properly bottlenecking but only found comparison between different cpu/gpu, no real what/why explanation. I was wondering is it just a matter of megahertz? What specs of the cpu or gpu is important to look for? Is the ram or motherboard involved?
So I ended up pairing my e6600 with a HD 4870. It is working flawlessly but I am wondering if am I also bottlenecking my video card without even knowing it? Does today’s high-end video card really need high-end processor also? It would be interesting to be able to calculate when would bottleneck occur for any piece of cpu or gpu. If anyone could enlighten us on this would be very great. For general knowledge, can cpu/ram bottleneck occur?
Suggestions:
Here’s maybe some things to start with:
CPU (socket, core speed, bus speed, bus/core ratio, number of cores…);
GPU (core speed, shaders speed, memory speed, memory bus width etc...);
RAM (frequency, latency…);
Board (Northbridge or Southbridge specifications).
Hope this will be informative for everyone. Thanks for reading and answering.
