iPhone 3GS

[Werewolf]

The iPhone 3GS has a 600MHz processor.

Does anyone know what the equivalent would be in P.C terms? I've been trying to do some tests with Chess Genius and I'm guessing around the same speed as a Pentium 100.

Can anyone confirm or deny that?
(Obviously I'm talking about speed for chess - not graphics power etc)

Maybe Majd Ansari has one like that. Why not run Glaurung for the iPhone if you can download that and post the results for the start position? That would be easy to compare with one of the latest Stockfishes. But a comparison with a PC would probably not make very much sense, they will always be so much faster than a battery operated device that is not really made to be an all round computer.

I can't answer your question, but here's a data point to consider:

Stockfish on a Q6600 at 2.4GHz: 3390 kn/s (starting position)
Stockfish on the iPhone 3GS: 51 kn/s (starting position)

So about a 66x speed difference for Stockfish.

Hi Eelco ... I really have no idea to check what the nps on the iPhone is. There doesn't seem to be that output. But I will say that Glaurung is my favorite chess application on the iPhone, and that would also include the paid versions. I hope the next version will not be free so that there will always be incentive to improve and add features.

Not many iphone chess apps display N/s.Glaurung, Shredder, Genius on my ipod touch don't.
Are you one of the Beta testers for Stockfish? As it has not been released yet as far as I know for iphone.The killer phone at the moment for speed is the Acer F1 neo touch that has a 1ghz Qualcomm Snapdragon.Gives speed up about 4x faster than the previous Intel X scale 624mhz arm cpu PocketPC devices.

Yes, I am one of the beta testers for Stockfish.

I corresponded with Richard Lang and he indicated that Chess Genius was getting about 70,000 nps on the iPhone. That was back in November 2008, so it's probably a little more now on the 3GS iPhone.

The Snapdragon sounds pretty fast! I imagine we'll even have multi-core processors on phones in the not to distant future...

Just to give a comparison on comparable clock speeds: on a Pentium III 500 MHz Toga 1.2.1a makes around 150.000 n/s (Arena 2.0.1), on my Dell X30i (XScale 624 MHz) it is around 32.000 n/s (PocketGrandmaster)

So the old P III should be around 5-6x faster than the XScale on equal clock speeds.

Wanted to add that it gets ~100kn/s in endgame positions.

I am curious, is that one thread or more (four)?

That was 4 cores. For some reason, I couldn't get Stockfish to run only one core in Aquarium. (I can't remember but maybe there was a seperate compile for the single-core version??)
