Benchmarks

The Gigabyte MA785GPM-UD2H has a hidden feature in the BIOS which when patched opens up the hidden core of some Phenom II X3 and X2 processors. In our test, we put the Phenom II X3 710 to the test and we benchmark it using 3 core vs 4 core in a few scenarios.

The first is the default timing with GPU running at 500MHz and side port memory at 533MHz. The second test is with GPU overclocked to 1GHz with voltage bumped slightly to the North bridge. The third test is with the patched BIOS that opens up the 4th core.

As it uses DDR2-1066 running at CAS 5-7-7-24-2T, it is natural that the memory bandwidth would be lower than the same processor running on boards support DDR3-1333. In fact, the memory bandwidth for this board is 11.6GB/s on the average. A board which supports CAS 7 DDR3-1333 board would give us around 12GB/s.

Arithmetic Processor test

With 4 core enabled, the increase in performance is noticeable. In Whetstone, the difference is 33% while Dhrystone gives a difference of 36%. As this is more of a test of the processor, the differences between a DDR3 vs a DDR2 board is very minute. The scores are almost identical.

Multimedia Processor test

The improvement in Multimedia test is quite noticeable too. In Int X4 test, the difference is 33% while in Float x8, the difference is 34%. When compared to a DDR3 AMD 785G board, the results didn't differ too much too.
