Synthetic Performance:

To start things off we'll take a look at PCMark Vantage numbers.  An interesting thing to note is that the both motherboards actually run slightly slower than the rated 200MHz FSB, and come in right around 2594MHz at stock speeds.  For the overclocked performance numbers, the A780GXE was clocked in at 13x 225MHz = 2925MHz while the AOD790GX was clocked in at its previously stated 14x 235MHz.  Obviously we expect the higher clocked motherboard to perform better in these benchmarks and it just shows what is available with the 790GX NB and SB750.  Memory was kept at DDR2-800 4-4-4-12 1T at both stock speeds and scaled slightly higher when we ramped up the FSB.

To gauge memory performance on the both of these boards we used Everest Ultimate.  For this test we used both stock and overclocked numbers and tried to keep the memory as close to DDR2-800 as possible.  You can see that the stock performance of the A780GXE/128M motherboard is actually quite a bit better than the other motherboard. All memory timings are exactly the same - 4-4-4-12 1T @ DDR2-800.  However, the overclocked performance of the AOD790GX/128M is clearly the winner as the high HTT speed helps us reach close to 8GB/sec read speed.

Finally we take a look at PM Core - a program that calculates prime numbers.  This program multi-threaded and we used it to calculate 10,000 prime numbers.  The results below are in minutes:seconds.tenths.  Once again, we've put up both ASRock boards against each other at identical stock and the highest stable overclock each board was able to achieve.



PMCore shows an interesting thing that other tests so far have not disclosed.  In this test the quad-core CPU performs identically on both motherboards in the single-threaded and multi-threaded test.  When overclocked, the AOD790GX gains an extra 9% performance over the slower-clocked A780GXE.

We wrap up the synthetic benchmarks with the infamous 3DMark Vantage.  While many will argue that this is not indicative of real-world performance, it is a simple and effective way to compare similar systems to judge how tweaking, drivers and different hardware can affect your performance.  This benchmark is effective at producing consistent results as it is scripted and 100% repeatable.  Once again we show stock 2.6GHz scores and overclocked comparisons at each board's highest stable overclock.

At stock speeds, both motherboards show very similar performance.  According to the chart, the AOD790GX board edges slightly in the lead and this lead is enlarged when overclocked as the AD790GX allows the processor to run over 300MHz faster.

On the next page we'll use real games and applications to better judge how these motherboards perform in real-world tasks.  These other benchmarks are great though if you want to directly compare your system.
