Clock speed doesn't really mean much these days. A 2.5Ghz i7 CPU is *significantly* faster than a 2.5Ghz i5, for example. My wife's 2.4Ghz iMac easily out performs my (rather old) 3Ghz Mac Pro at most general purpose tasks (but not video encoding).

Mhz is a measurements of CPU cycles, *not* a measurement of how much is actually done during each of those cycles. You could measure in MIPS (millions of instructions per second), but that depends on the task that the CPU is doing.

The A5X may have other tweaks we dont know about yet - such as memory bandwidth or additional instructions, all of which could make a huge difference to performance, one way or another.

i7 and i5 are simliar but several internal features are different. Clock speed is relevant when all else is identical.

All indications point to the A5X using the same CortexA9 micro architecture with ARMv7 instruction set. Geekbench2 from the article shows memory throughput, and synthetic math performance identical. No, don't expect any CPU related performance gains.

iOS is heavily GPU optimized and accelerated, text rendering, UI elements, it may very well run faster.

I still believe that if u own an iPad 2 then there s no point in upgrading to iPad 3. Quad core iPad 4 would be a bad boy and I m waiting for it already!

Also. the iPad 2 had 900 Mhz not 1 Ghz

This disappoints me because I was planning on putting a bunch of HD .mkv files onto my iPad3. 3rd party media players on the iPad can't utilize the GPU, only the CPU. They ran like crap on my iPad1, I haven't tried it on an iPad2 though, so hopefully the iPad3 is good enough to play 1080p mkv files. Converting/demuxing is a bit of a hassle, but I guess that's what I'll do if need be.

Don't count on it. Run them through Handbrake before sending them to iPad/iPhone using standard h.264 profiles. Then the hardware accelerated decoding engine can handle the video smoothly.

Compared to the overall score of 454 on the iPad 1, I think my money upgrading was well spent.

Considering this is my FIRST iPad. it is money well spent. I skipped over iPad 2 because of lack of retina
