Help with hardware
I'm about to buy a computer And I am bafled by a the apperant difrence between a Phenom x6 or a i7 2600k one is 6 core but the other is 4 core 8 thread.

Can I compare core against thread ? or how do I compare ?

Do I compare 6 vs 4
or
Do I compare 6 vs 8

This is specificaly a question for rendering with KT

This is a big dilema for me, please help.

6 cores, single threads
4 cores, hyperthreads (2 threads per core)

to see performance with KT, take clock speed and multiply by #threads:

which Phenom are you talking about?
I'll go with ... (3.3Ghz)


with a (3.2Ghz)

So, 3.3x6=19.8Ghz processing on your render with the Phenom

The 2600k is 3.4Ghz
So, 3.4x8=27.2Ghz processing on your render with the Corei7

27.2/19.8=1.37, so the Corei7 is 1.37 times faster than the Phenom.

Here's a

Not much to think about there... the little money saved is not worth the increased render times. (IMHO)

Get the 2600k, and overclock it to over 4Ghz and you are a very happy camper.

(overclock at your own risk and only with guidance from folks that know what they are doing - like at overclockersclub.com)
