Hardware, Embedded Systems Quite a bit of enthusiasm seems to be building for ARM's upcoming processor for netbooks and other lightweight computing devices. The Cortex-A9 is promised to have substantially better performance than the current crop of AMD processors, and a video released by AMD ARM gives a pretty convincing picture that the Cortex-A9 will have comparable performance to the Atom. Watch the video after the jump.

Why Compare?

The video is a nice demonstration of what the cortex can do. I wonder though, why did they want to compare there dev board to a production machine with accelerated video? This only makes there product look inferior.

Surely there could have been better cpu bound benchmarks that would have showed off the capabilities better. I do not mean to be negative however this seems like shooting yourself in the foot. A comparison of how many hours of dvd decoding on the same battery, for example would have been more interesting to me.

They showed graphics for the same reason it's hard for the software verification researchers to compete with the graphics researchers at a poster session.

That would be a piss poor way to handle it, to me. Anybody can make a CPU that does well with high-throughput tasks. The trick is making it good as a desktop CPU, where random things happen all the time, with low IPC, cache misses all over the place, but still being responsive.

A specific <piece of hardware>-bound benchmark is exactly what should not be used, as my real-world usage is going to be nothing like that.

A picture and short, easy to understand sentences are worth their weight in gold. I got out of this video:

1. Nearly as fast without a GPU as an established product with a GPU.
2. Running at 1/3 power of the competitor.

I say WOW. Place that into some fine hardware combined with a fine GPU and you should be smokin', while saving battery power.
