performance gains: pentium D 2.3ghz vs. 2.26ghz core 2 duo/i3

[boostmiser]

I'm holding out for a supposed 13" i3 mbp.
I've got a Windows machine with a Pentium D 2.3ghz and 3g ram.
Using Photoshop or video editing software, what type of performance gains, if any, should I see with a 2.26ghz core 2 duo and 4g ram? What about with the i3 and 4g ram?

It's not just the CPU and RAM you have to consider. The performance gains with Mac OS X vs Windows will be a factor, as well. Overall, you'd see a noticeable improvement.

Erm.. Photoshop runs slower on Mac OS than windows.

Maybe that's your experience, but not everyone's. Also, it depends on the CPU and RAM, as I said. All 3 factors contribute to the overall performance.

No, thats just the way it is, CS4 is 64bit on Windows.

From John Nack's blog:

In our testing, when an app isn't using a large data set (one that would otherwise require memory swapping), the speedup due to running in 64-bit mode is around 8-12%.

Well take this into consideration clock for clock, when core duo was launched it was about 50-60% faster overall per clock then a pentium D. When Core 2 Duo was launched it was another 20% faster than Core Duo. When Core 2 Duo Peryn came out it was another 10% faster clock for clock. The Core i7 is about another 25-30% faster clock per clock plus incredible amounts more power saving features and a built in TDP overclock. So adding that up your looking at something around 120% faster clock for clock then your Pentium D per thread and the new core series has 4 threads not 2.

Edit: By the way in terms of getting the new core chips yes core i3 is still fast but save some money and get a core i5 minimum. The i3's don't include TDP overclocking and have a smaller cache.

You're assuming CS4 and a 64-bit Windows OS. CS3 runs faster on Mac, and not all Windows users are running 64-bit. Many are still using XP, for example. Therefore, your blanket statement that "Photoshop runs slower on Mac OS than windows" is not accurate in all cases.

I believe you need to multiple those percentages not add them. Like 150% * 120% *130% * 110% = 2.57. So the new core ix would nearly 3 times as fast.
