Benchmarking overclocked TP2s

[garyflynn]

Now that we have good options for overclocking the TP2

http://forum.xda-developers.com/show...&postcount=162

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.

[pesok]

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

[matchstickredgti]

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

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

definitely an improvement

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

Besides SPB Benchmark I also use this little app:

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
