Everest CPU Benchmarks
Lavalys 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 test bed: 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. While the EVEREST CPU tests really only compare the processor performance more than it measures platforms, it still offers a glimpse into what kind of power each platform possesses.
Queen and Photoworxx tests are synthetic benchmarks that operate the function many times 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.
Since the benchmark tests in Everest aggressively exaggerate CPU performance, we also expect that the final scores are equally exaggerated as well. Showing a real edge over quad-core architecture in Queen tests, Intel's Gulftown pushes past the i7-920 and leads the pack using its raw processing power. Even the overclocked 4.0GHz AMD Phenom-II X6-1090T can't produce Queen CPU performance close enough to match the Intel 980X.
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:
If CPU PhotoWorxx in any indicator of pipeline architecture penalties, then the AMD Phenom-II X6-1090T is in trouble. Scoring significantly lower than the AMD X4-965, the X6-1090T can't even compete with the other processors in terms of amplified PhotoWorxx performance.
The Zip Library test 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.
Since I'm also the webmaster for Benchmark Reviews, I find myself using file compression programs almost as much as I use web browsers. This makes the CPU Zip library tests very important to me. Compared to Intel's Core i7-980X processor, the AMD Phenom-II X6-1090T hexa-core CPU offers decent Zip-archive performance in stock form, and it becomes more comparable once overclocked.
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.
Encryption is a technology that has come to the forefront of personal computing, and will become more common with everyday computing as the world becomes more competitive. Generally seen in the corporate enterprise segment, file encryption is steadily becoming a topic of discussion for personal computer users. So when the Intel Core i7-980X arrives and dominates the AES Encryption test by more than 1025%, it's time to sit up and take notice. Simply put, Intel's Gulftown architecture delivers enterprise-level performance to encryption tasks.
