benchmark new smartphones: (Old Thread)

[Ponti]

I'm interested in buying a new cell phone...

[mclane]

Ifo you want to do chess with it I would advise to buy a used samsung note II with exynos quad CPU.
It's second I'm the list, has a large screen good for chess and web surfing (5.5 ") and has a big battery that lasts long. Buy it used so you get the most for your money. Put a big memory card into it and you have a very good mobile.

Too bad Note2 uses AMOLED screen which is prone to burn-in especially when you always view static graphics. Best example of static graphic is Chessboard. Ouch!!

[mclane]

But you Look for Email, do websurfing, dual numbers and and and. The Board is Not always on top. I have no Problems with my Note 2 and you can believe me that i am heavily using it for chess. Its still the fastest mobile for Memory computerchess. Maybe the samsung galaxy S5 with 64 Bit exynos octacore will change in 2014. but today it is still fast as an Android phone.

I am not sure if there is a real comparison of the complete list. In the future it could be better to add informations about OS-version and App-version.

My results for some iOS-devices, using iOS 7.02 and Stockfish 2.7.0 (2013/09/26)

iPhone 5S:
1095.6 kN/s

iPad 4:
587.7 kN/s

iPad 3:
293.8 kN/s

Yes,I get the same kN/s on my iPad 4 and I wonder about the huge difference between it and between iPhone 5s....

I am not sure about the A6X (iPad4) and A6 (iPhone5) but Apple declares the new A7 two times faster than the "A6" (A6X?).

A6 is 2cores (1,3 Ghz) 32-bit, A6X is 2cores (1,4 Ghz) 32-bit (ARMv7), but the new A7 is 2cores (1,3 Ghz) RISC 64-bit (ARMv8). I think iPad 4, iPhone 5 and iPhone 5s have 1 GB RAM.

Congratulation for upgrading to the 4 inch screen! Do you feel much better than the old 3.5? Now you can see three multi-pv variations on SmallChess! : - )

A7 chip itself is a much faster chip than A6. It also runs 64 bits which is a killer feature for chess. It is not a improvement for 99% of the application, but chess belong to the 1%. When I run the same engine on the same device for 32 bits, the improvement was just modest. My observation tell me the huge speed up is due to the 64 bits architecture.

That's about right....

I do think that 64bit hardware will help tremendously in chess, but is there any engine designed for Android or Apple OS that runs in native 64 bits? I think there would need to be new compiles specifically for 64 bits and not sure if Apple would accept as that would make the application void for basically all previous versions of hardware. I guess you could have the application with both 32 and 64 bit code, but maybe that would be very tricky to do.
