What's the difference between Processor Cores, and Processor units?

post #1 of 12
Thread Starter 
Whenever I look at specs for graphics cards, under the stream processor section, Nvidia cards say 'x' amount of Processor Cores, and AMD says 'x' amount of processor units, or stream processor units. What's the difference between the two. Nvidia's 580 has 512 processor cores where as teh AMD 6970 has 1536 stream processing units and the Core clock for the 6970 is higher then that of the 580 (as far as the ASUS cards are concerned). Those two cards are at the top of the food chain now, and their specs are pretty different. Are processor cores and units different, because if not then how does the 580 have a third of what the 6970 has and is almost 150 dollars more?

uuh core clock and processing units cant be directly compared between amd and nvidia

i think to get even processing units its amd stream processor/5 = nvidia equavelent
i might be wrong
i read this somewhere

The design of the cards are completely different. So you should not try to compare a NVIDIA to AMD based on core count.

+1 and although they can't be compared directly
the ratio is 5:1(that is for each nvidia core ati has 5 processors....)

the 6970 is NOT amd's best offering.
i am tired of people saying that.
currently, the 5970 is amd's best card.
