Comparing processors and motherboards.

An AMD processor compared to Intel Core i5-4670K 3.4GHz Quad-Core Processor. Would even like to find an 8-core.

And a Asus Z87-A ATX LGA1150 Motherboard compared to an AMD motherboard.

Thanks
 
You need to compare the processors first.

AMDs best CPUs are half the speed of Intel, clock speed for clock speed.

In other words it takes an 8 core AMD running at the same clock speed as an Intel 4 core to even come close.

If you are running programs that need a lot of cores, for cheap, AMD can still be a good choice.
 
AMD's 8 core is 4 physical cores with 4 "logic" cores, intel calls this hyperthreading so a quad core i5 = an 8 core AMD as far as number of cores.

The i5 4670 beats the FX-8350 in pretty much every way except the price. Now it is not twice as fast as some may imply but it is a noticable bit faster.

As far as the motherboard goes you just get one that has the features you are looking for, a 990FX chip would be the best equivilant to a Z87.

For my needs i bought an fx-8320 because it had enough power for my needs vs the price point I was wanting to spend. If I had a bigger budget and was not aleady using an AMD board I would have spend the extra money for an i5.
 


The reason they clock near the same is not because a 4 core i5 is twice fast per core as an 8 core AMD, it is because they actually have the same number of cores. AMD 8 core = 4 physical cores, each physical core = 2 logical cores. The i5 uses hyperthreading and thus each physical core = 2 logical cores. The difference is that intel advertises it is a quad core and AMD advertises it as a octa-core.

The amd logical cores is similar but not the same as hyper threading, the end result is being able to process the same number of threads at one time (an 8 core AMD vs a 4 core Intel with hyper threading). I was incorrect in that the quad core i5s do not have hyper threading, the dual core i5 does but not the quad core.
 
I am aware that some dual core i5 have hyper threading, but we have been talking about the Quad core all along.


I don't know why we are arguing, as we seem to agree, that Intel core for core at the same clock speed is twice as fast.

Edit
They look physical to me.
