How much slower is the 2.16ghz MBP vs. the 2.33? (Percentagewise)
Well, considering that the bus speed and L2 cache are the same, and assuming that you're not doing anything that requires the RAM to be pushed, or you upgrade the 2.16 to 2GB then:
around 7.7% faster
Not really worth the extra money to upgrade in the apple store then. probably wouldn't even notice that
thank you! would it be possible to upgrade the 2.16ghz machines to 3GB RAM?
then again, the 2.33 machine also has double the video memory..
All C2D MBP's support upto 3Gb of Ram
It does indeed, but not entirely essential unless you intend of using an extental moniter in dual mode.
You can't just do 'percentages' when figuring out if a computer is faster or slower.
Did 'the megahertz myth' teach you nothing?
Alright guys, the 2.16 MBP against the 2.33 MBP cannot be settled by simple division.
It takes preformance tests, speed tests and an understanding of what type of work your going to be doing on these machines.
If your going to do video or photo editing you probably want the 2.33 because more video ram and the speed bump.
Really, i know he asked for a percentage but its just incorrect to tell him without some sort of disclaimer.
Huh? This has nothing to do with the 'Megahertz Myth.' We're not comparing Intel to AMD or PPC here... we're directly comparing IDENTICAL chips with different clock speeds. Of course you can describe the performance difference with clock speed. And as far as applications, he didn't specify what he was going to use it for, but people just want to know generally how much faster something will be... who knows what you'll need that CPU for in the future?
Now, why he couldn't do division by himself confuses me. If you can make a purchase decision on a $2500 machine, then why can't you use a calculator?
Notice I said around 7.7%. Obviously it's not going to be exactly that in every single task, but since they're very similar machines, the main difference being clock speed on an otherwise identical chip, I think it's fair to say that the 2.33 would be about that much faster generally.
And yes, you can upgrade the 2.16 to 3GB of RAM.
because the Calculator on my 1GHZ TiBook runs very slowly when I try to record music in DP while trying to surf MySpace + YouTube.
I was just trying to figure out how much of a speed difference that is in "real-world" terms. And also from people who've used it.
I dare say you'll notice very little in terms of real-world performance. The extra 7% comes into play in only the most performance intensive tasks, i.e. video encoding, 3d rendering, etc.
What performance tests always show is that division doesn't mean anything. Look at that 7.7% that was calculated mathematically, and tell yourself that you won't even get that high an improvement in most tasks. Based on that 7.7% mathematical approximation, I'm going to guess 4% for most tasks. The benefits of the 2.33 GHz machine won't be 7.7%, and could never be higher with every other factor being the same.
