EVEREST Benchmark Tests
EVEREST Ultimate Edition is an industry leading system diagnostics and benchmarking solution for enthusiasts PC users, based on the award-winning EVEREST Technology. 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 testbed: Queen, Photoworxx, ZLib, and AES, all rely on basic x86 instructions, and consume very low system memory while also being aware of HyperThreading, multi-processors, and multi-core processors.
Coming out of the gates, EVERESTs Queen benchmark puts the Intel Core i7 920 over 31% ahead of the AMD Phenom II processors. Don't let the benchmarks fool you though, because the Queen and Photoworxx tests are synthetic benchmarks that operate the function many times over and over-exaggerate by several magnitudes 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. The EVEREST Photoworxx benchmark performs the following tasks on a very large RGB image:
While the triple-core X3 720 doesn't prove very effective in Photoworxx testing, it didn't seem at all sluggish when I used it for real-world photo manipulation activities. But doing them synthetically better is what benchmarks are all about. What becomes strange then, is that the quad-core Phenom II X4 810 and X4 940 perform nearly identically. Of course, the Intel Core i7 920 clears the entire lot by a 51% margin.
The next synthetic benchmark we've selected measures combined CPU and memory subsystem performance through the public ZLib compression library. ZLib is designed as a free lossless data compression library for use on virtually any computer hardware and operating system. The ZLib data format is itself portable across platforms and has a footprint independent of input data that can be reduced at some cost in compression. In our tests, the Intel Core i7 920 certainly shows it's muscle and might as the top-performer with 89.8 MBps Zip library compression. Not far behind however, the AMD Phenom II X4 940 offers nearly as much performance with 80.3 MBps.
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 48 MB of memory. The Phenom II X4 940 processor comes in at the top with a score of 21713, following behind by only 2% is the Core i7 920 with 21276. Next is the AMD Phenom II X4 810 with a score of 18850, with the X3 720 finishing out the testing with 15216.
