AIDA64 Benchmark Results

AIDA64 is a full 64-bit benchmark and test suite utilizing MMX, 3DNow! and SSE instruction set extensions, and will scale up to 32 processor cores. An enhanced 64-bit System Stability Test module is also available to stress the whole system to its limits. For legacy processors all benchmarks and the System Stability Test are available in 32-bit versions as well. Additionally, AIDA64 adds new hardware to its database, including 300 solid-state drives. On top of the usual ATA auto-detect information the new SSD database enables AIDA64 to display flash memory type, controller model, physical dimensions, and data transfer performance data. AIDA64 v1.00 also implements SSD-specific SMART disk health information for Indilinx, Intel, JMicron, Samsung, and SandForce controllers.

All of the benchmarks used in this test- Queen, Photoworxx, ZLib, and hash- rely on basic x86 instructions, and consume very little system memory while also being aware of Hyper-Threading, multi-processors, and multi-core processors. Of all the tests in this review, AIDA64 is the one that best isolates the processor's performance from the rest of the system. While this is useful in that it more directly compares processor performance, readers should remember that virtually no "real world" programs will mirror these results.

The Queen and Photoworxx tests are synthetic benchmarks that iterate the function many times and over-exaggerate what the real-world performance would be like. The Queen benchmark focuses on the branch prediction capabilities and misprediction penalties of the CPU. It does this by finding possible solutions to the classic queen problem on a chessboard. At the same clock speed theoretically the processor with the shorter pipeline and smaller misprediction penalties will attain higher benchmark scores.

Like the Queen benchmark, the Photoworxx tests for penalties against pipeline architecture. The synthetic Photoworxx benchmark stresses the integer arithmetic and multiplication execution units of the CPU and also the memory subsystem. Due to the fact that this test performs high memory read/write traffic, it cannot effectively scale in situations where more than two processing threads are used, so quad-core processors with Hyper-Threading have no real advantage. The AIDIA64 Photoworxx benchmark performs the following tasks on a very large RGB image:

  • Fill
  • Flip
  • Rotate90R (rotate 90 degrees CW)
  • Rotate90L (rotate 90 degrees CCW)
  • Random (fill the image with random colored pixels)
  • RGB2BW (color to black & white conversion)
  • Difference
  • Crop

The OC Genie automatic overclock adds 19.99% to the Queen score and 14.78% to the Photoworxx score. My manual overclock, while only slightly quicker, increases the scores by 28.54% and 15.05% respectively.

The OC Genie scores are 19.92% and 20.06% better than the base scores, while manual overclock scores are 21.01% and 22.69% better. Now let's try some real-word benchmarks with SPECviewperf in the next section.

"Take from this what you will, but the results are clear cut enough to convince me that that it is worthwhile enabling the power saving settings available on the MSI Z77A-G45 GAMING motherboard. In the 60's and 70's there was a big ecology movement after oil prices had risen sharply and we collectively realised that we could not sustain our then current level of consumer lifestyles. In the ensuing years the economy changed for the better and consumption ramped up sharply. We now find ourselves consuming more than ever and we once again need to realise that natural resources can't possibly sustain us forever. We need to demand more energy efficient products. We need to demand better built and longer lasting hardware. But most of all, we need self control and a more conscious approach towards our consumer habits"

What a fantastic quote, very unusual for a MB review. Bravo

Thanks for the kind words Will. :)

"I didn't spot it right away but a closer inspection of the VRM/phase heatsinks reveals that they are shaped like the head of a dragon. This is a nice touch but it will be inevitably lost in an enclosed system with a large CPU cooler much like my own."

This may be true, but YOU know they are there :)
