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.

Don't understand the mother board question.
Do you think a company like Asus makes one type better than the other?
Can't imagine why.

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.

Asus M5A99X EVO R2.0 AM3+: $125 before $20 rebate

To imply that an Intel processor is 2X faster than an AMD processor could be be qualified as "outrageous hyperbole"

Unless you look at the facts.
I used to be an AMD fanboy also.

Edit
Take an Ivy bridge i5, over clock it to 4gig. (only 4 cores)
Compare it to an 8 core AMD, running @ 4Ggig.

They bench very close.

I haven't even played the i7 card yet.

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.

I din't know where you are getting your info, But the i5 dose not have hyper threading, only the i7 dose.

The AMD 8 cores, do have 8 cores, they have 4 modules or what ever AMD calls them, and each Module has 2 cores, sharing cache.


http://www.tomshardware.com/answers/id-1944789/differen...

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.

I made the mistake of assuming that the quad core i5 has HT since the dual core did, i just wanted to state where i was wrong but that the AMD was not a true 8 core.
