Performance Delta Banias Vs. Core 2 Clock for Clock

[phaxmohdem]

I had the depressing realization that my trusty laptop has fallen several CPU generations behind. It got me wondering, how much better is a Core 2 chip over my Banias Processor clock for clock.

I have a 1.6GHz chip, how many GHz would my processor have to be to equal the performance of a 1.6GHz Core 2 Chip (Single threaded, disregarding the obvious Dual Core difference)

Banias is hard to judge. It had half the l2 of Dothan, and Dothan could only occasionally match the speed of a single-core K8 clock-per-clock. Even at its worst, the Core 2 Duo will be about 20% faster per clock than Banias, and in some instances it'll blow Banias away.

The thing with Core 2 is that it's not that fast unless you reach around 2.4 GHz with it, and past that the Core 2 just takes off.

I have a Merom in my laptop @ 1.83 GHz and it's not much different from my old A64 @ 2.5 GHz. The only noticeable difference is video encoding, and it's quite a big difference but that's partially to do with it being dual core.

I'd say that the clock for clock difference between Core 2 and Banias is in the 25-30% range most of the time.

hell, i bet its more than that. isn't core 2 already 15% faster than core? (Yonah v Merom)

Dothan is faster, clock for clock, than K8, for sure. I have two notebooks HP nx6125 (Turion ML-34 Lancaster 1.8GHz 1MB L2) and nx8220(Pentium M 760 Dothan 2GHz 2MB L2). I've tested them in Matlab, Simulink, VS 6 compiling and code execution, VS.NET compiling and code execution, MySQL, Visio, Photoshop, Premiere, DivX and other.
The Dothan is marginlay faster, clock for clock in most of the software.
Dothan is also marginaly faster than Banias: core enhancements and more L2.
For single-threaded apps Core2 is 20%-25% faster than Banias

When people say K8 they usually refer to Desktop, dual-channel DDR parts. Lancaster IS slower than Dothan (slightly) but mostly because of its single-channel memory and its relatively low clocks (PC2700, for the most part). That said, I'd say that Core 2 really is 25%+ faster than Banias, clock for clock. Hell, it may be more than 30%!
