besides, won't all future Opterons based on K10 be quad-cores? I doubt the "Opterons" in this test were K10

No, you don't understand.

It is 2x performance. The task is to process n pixels. K10 processing 4000+(it is said more than 4000, not exact number. So I assume 4400 pixels/s according to the times) pixels per second and finishes the processing for 56 seconds. For the same task the K8 needed 112 seconds because it was processing 2200 pixels/second.

It is like you have two cars on a drag race and the faster car finishes the race after 56 seconds with average speed of 200km/h. The slower car finishes the race after 112 seconds with average speed of 100km/h. The faster car is 2 times faster than the slower car, not 4 times.

Got it?

the drag strip is not a good example, because they both have 1 engine, but what you are saying is that one car has a better motor, so it not only finishes in a faster time, but accelerates faster which helps it get the better time

so, is the ~4000 pixels/s due to more cores, or better cores?

is the less time due to more cores, or better cores?

i assume the more pixels/s and less time are due to both more cores and better cores

if you were to pit 8 K8 cores against 16 K8 cores, would it still perform more pixels/s at a ratio of 2:1 AND less time at a ratio of 2:1 like this?
