Stockfish mobile benchmarks

[Tord Romstad]

Great news! I don't have an iPad (yet!) but I have played around with one. I think it's really quite revolutionary in that it's an ideal device for relaxing with on the couch.

Yes, it is. I find it amusing to see all the criticism from all the people who doesn't understand the purpose of the device, and complain about all the things it can't do. They fail to understand that it isn't designed to do absolutely everything, but rather to do the things it do with maximum comfort and user-friendliness. I already love mine, and am sure I'll use it far more than my iMac and my MacBook.

I'm sure Glaurung for the iPad will be wonderfully successful. I hope you charge something for it - at least $0.99.

I won't, and there are plenty of alternative programs for those who prefer paid applications.

I've done some more work this morning, and now have an early prototype running on my iPad:



It isn't as close to finished as it looks: There is still no support for landscape mode, the toolbar needs to be redesigned for the iPad, and the menus and dialogs still appear in separate screens (like on the iPhone) rather than in popovers (as in most iPad apps).

In my benchmarks so far, the iPad appears to be about 25% faster than the iPhone 4.

I have stockfish 1.9.1. I am running android 2.1. I oc theprocessor to 1.3, I had it at 1.4 however it was unstable. 1.3 has been stable and has given me better battery life.

Thanks for the clarification, will be interested in the performance with Android 2.2.Does any one have Samsung Galaxy series with Android 2.2?
The official Samsung release is still delayed but there have been some beta releases.I imagine that with Froyo you will see dramatic improvement.

Hi Tord,

so perhaps the CEboard programmer or the programmers from Pocket Grandmaster read your message.

THANKS for your answer!

Hi folks

SF 1.9 on my Android cellphone makes 200 kn/s (opening position).

CPU?

[Daniel Mehrmann]

ARM v7 Qualcomm 8250 (Snapdragon) OC@1,4 Ghz

I'm proud owner of a Nexus One by Google with AMOLED display.

Well, OC speed was just for this test. I'm not using it as daily driver

Best,

I imagine it would be in Kai Skibes interest to offer the StockFish 1.9 as an additional engine.Might generate more sales of PGM.

Can you guys post your benchmarks (avg kn/s for starting position) for Stockfish for various mobile devices.

I have Ipod touch 2nd gen and stockfish on glaurung 2.1 gets about 16.5kn/s after a 1min.
I have a Samsung Vibrant and stockfish 1.91 on Droidfish avgs about 111 kn/s after 1min.
I've messed with a Iphone 4 but vaguely remember the benchmark was from 140-150kn/s (I'm 80% sure though).

Can someone post for other mobile devices (like evo, epic, hd2, iphone 4 and 3gs, etc.)

New iPad: around 160 kN/s
So nothing new regarding chess (only the GPU was upgraded, AFAIK).

thats indeed disapointing. the new hardware is only good for graphics and the higher screen resolution. so we don't have to upgrade our ipad2 into ipad3.

that could change the situation in 2012 completely IMO.

in this year Tegra3 will come out, with 4 cores . also huwai has a strong cpu for mobiles and tablets.

could be the first time other companies can overtake apple because apple failed to increase hardware power (far from GPU stuff).
