Benchmarking overclocked TP2s
 

Now that we have good options for overclocking the TP2

and

http://forum.ppcgeeks.com/showpost.p...&postcount=281

Does anyone have any ideas for measuring the impact of different clock speeds in an objective way?

For example is there a video player that will display the amount of frames per second it is able to process or a calculation intense procedure that we can have the TP2 time?

I considered using a stopwatch to measure boot-up time, but realized that the methods we have set the clock speed late in the boot process, so I couldn't expect any change in speed.

spb benchmark.

Here are my results with SPB Benchmarks v1.6. All results are in Ms and lower is better/faster

ROM = Formula's SPB MobileSense 3.5.5 - Formula.LD.23563.E.080410.exe (WM 6.5 COM5)

Clean flash done right before tests with Task29 prior(to assure integrity)
Fresh reboot + 2 mins wait(to make sure startup apps are fully loaded) done before EACH run.

As you can see OCing to 787Mhz brings tremendous benefits. Not a single problem during overclocked state.
Did not notice any excessive battery drain, nor did phone overheat during intensive benchmarking(Battery temp stayed under 40c)
All the tests took a bit over 3 hours, hitting thanks button takes less than 3 seconds:),
but then again i didnt do it for thanks

Re: Benchmarking overclocked TP2s
 

my results from benchmark test at 518mhz and at 787mhz

http://forum.ppcgeeks.com/showpost.p...&postcount=285

definitely an improvement

Re: Benchmarking overclocked TP2s
 

you should probably thank mangomango for posting spb benchmark for you to do those tests ;)
and you should probably thank the people that put together the oc'ing tools, and scripts ;)

nice numbers, thanks for posting them

Re: Benchmarking overclocked TP2s
 

Besides SPB Benchmark I also use this little app:

Re: Benchmarking overclocked TP2s
 

I been running spb bench ever since OCing became possible, and posted link to the download cab few weeks ago on this forum. Also those tests were done about 5 days prior to the time of my post in this thread, since its a copy from my other thread-and there i thanked all that were involved
