EVEREST Benchmark Results

EVEREST Ultimate Edition is an industry leading system diagnostics and benchmarking solution for enthusiasts PC users, based on the award-winning EVEREST Technology by Lavalys. During system optimizations and tweaking it provides essential system and overclock information, advanced hardware monitoring and diagnostics capabilities to check the effects of the applied settings. CPU, FPU and memory benchmarks are available to measure the actual system performance and compare it to previous states or other systems. Furthermore, complete software, operating system and security information makes EVEREST Ultimate Edition a comprehensive system diagnostics tool that offers a total of 100 pages of information about your PC. All of the benchmarks used in our test bed: Queen, Photoworxx, and AES, rely on basic x86 instructions, and consume very low system memory while also being aware of Hyper Threading, multi-processors, and multi-core processors.

CPU Benchmarks

The last time I tested the AMD AM3 platform with Everest Ultimate Edition and the triple-core 720 Black Edition Processor, it kicked the Intel E7300 Core2 Duo to the curb on this test suite. This time, it's Intel who gets to do the kicking, with its i5-750 doing the honors.

The EVEREST Queen benchmark shows some nice scaling with the i5 overclock, just like a good synthetic benchmark should. The i5 with 4 cores and standard clocks beats the triple-core 720BE by about 30%, which makes sense. 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.


The Photoworxx benchmark tests for penalties against pipeline architecture. This synthetic 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. The EVEREST 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 Everest documentation hints that this benchmark is highly dependent on memory write speed, and we've see ample evidence of that in prior tests. Here we see a huge gain by the ASUS P7P55D-E Pro motherboard, in part due to the strength of the integrated memory controller on the Lynnfield CPU. The Phenom II X3 with its integrated memory controller blew the Intel Core2 Duo systems out of the water with a 74% gain in previous tests, so think of this test as more of a memory + CPU benchmark. The results also scaled nicely with the overclocks on the i5 CPU, even though the memory speed remained constant at 1600 MHz.

The AES integer benchmark measures CPU performance using AES data encryption. It utilizes Vincent Rijmen, Antoon Bosselaers and Paulo Barreto's public domain C code in ECB mode and consumes only 48 MB of memory. The AES test produced a close call between the ASUS P7P55 board with a stock i5-750, and the ASUS M4A79T with its overclocked Phenom II X3 CPU. Once the i5 gets its own overclock, it pulls ahead but not to the same degree that it does in the other tests in this suite. Clearly, Intel had a good reason for upgrading the AES algorithms in its latest processors.


The Zip Library provides another opportunity for the AMD platform to shine. In the end, it's still no match for the i5 platform and its new memory controller. Once again, the ease at which this motherboard and processor combination overclocked means that higher levels of performance are just a few well-placed keystrokes away.

So far, memory performance seems to have had an impact on some of the synthetic benchmarks in Everest, so it's a good idea to look at the pure memory benchmarks that are available in the test suite. EVEREST Ultimate Edition offers three simple memory bandwidth tests that focus on the basics; Read, Write, and Copy. In order to avoid concurrent threads competing over system memory bandwidth, the Memory benchmarks utilize only one processor core and one thread. This will also aid in equalizing the comparison here between Quad and Tri-Core processors.


Once again, we see that Intel has a winner with their new Core microarchitecture, and particularly the i5, with its integrated memory controller. There's no contest here, and it's also good to see that upping the Base clock and the CPU clock extract even more performance from the system.

Now, let's look at some additional benchmarks with PCMark Vantage.

Great review, thank you.

I'm a little confused by the choice of ASUS p7p55d-e motherboards: standard, lx, pro, evo, deluxe, premium.

Is there is real reason to choose the deluxe version over the pro version reviewed above (I'm not an overclocker, so not sure if all the power lanes will make a difference, and the only other differences I see are the variety of audio ports and an extra LAN port)?

Thanks for any advice.

I agree... the product line seems to get spread a bit thin.

If you're not overclocking, then search for the best price to fit your needs. All P55 motherboards, regardless of manufacturer, will produce roughly identical performance results (minus OC). Just make sure that it has the extra features you might need down the road.

Thanks for the advice, I'm conscious of the fact that perhaps a couple of years on I may need something that I didn't buy into initially, just to save some money at the time.

Putting it another way, is there a disadvantage of the Deluxe over, say, the Pro version (e.g. power consumption), apart from the price?

Power consumption is too close to declare any substantial difference. The biggest differences are in the features: heatpipe cooling, overclocking tools, additional NIC, ports, etc.

Thank you for your quick respones - I didn't see the extra cooling features of the Deluxe version, so that is a nice bonus.

Audio CODEC (VIA VT2020) has more features.
Dual LAN Controllers with "Teaming" feature.
TurboV remote control included with Deluxe.
16+3 PWM phases v. 12+2.

If you're not overclocking, and you don't need the two extra audio channels and you don't need dual NICs, then don't spend the extra money. I don't see any of the included features helping to future-proof your system. The USB 3.0 and the SATA 6Gb/s are the keys for that, and both boards have that.

Amazing review. Good to see the AMD board in comparison.
