Why is it that when you upgrade from an i3 to i5, you are actually getting a lower speed in the i5?

Because the i5 750 is a quad core. Most quads have lower clock speeds than dual but have much more muscle and will have better performance

Then what about when you switch from an AMD quad core to an Intel quad core of similar prices. The Intel speeds are much less...

There are many more factors than just clock frequency that affect a CPU's performance.

Cache is one. You'll want as much of that as possible

Most of the higher end Intel quad core, like the i7 920 has hyper threading, which helps it process alot better than a similar amd processor

What about the Phenom II x4 965 compared to Intel i5 750. They are both quad cores and have a cache difference of only 2mb, yet the AMD has a speed of 3.4GHZ while the Intel only has 2.66.

2 MB can make a noticeable difference especially when i think they have 8 or 6 MB in total. 2.6 GHz of one processor doesnt equal to another CPU at 2.6 GHz. You also have to look at the architecture of the CPU and CPUs are very complex so its pretty hard to get into really specific details.

And yet the Intel will still beat the AMD. Again alot of things go into the power of a cpu, likes its memory support, memory controller, etc.

the architectures are totally different and they have different manufacturing processes. You cant compare them by their speeds or total cache, you can only compare them in real time benchmarking.

This.

If you want to compare specific CPUs, your best bet is looking up reviews.

Sites like Tomshardware or hardwarecanuks are my personal choices for that kind of thing.

i like how tomshardware compares it with a large amount of other products but sometimes they get really random performance compared to other benchmarks. anyways for CPUs and GPU reviews i go to overclockersclub or anandtech and sometimes guru3d.
