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 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.

Topping the results of our Queen CPU tests, the 2.80GHz Intel Core i7-860 and Gigabyte GA-P55-UD6 motherboard lead with 29389 points. Next is the 2.66GHz Intel Core i7-920 for 25786 points, trailing behind 12%.

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:

• 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

Although the 2.80GHz Intel Core i7-860 and Gigabyte GA-P55-UD6 motherboard still lead in the PhotoWorxx results with 32825 points, the 2.66GHz Intel Core i7-920 is practically even with 32739 points.

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.

Similar to the PhotoWorxx tests, the Core i7-860 and Core i7-920 are tied for the lead, performing at 95,540 and 94,758 KBps respectively.

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.

Taking back a more decisive lead, the 2.80GHz Intel Core i7-860 and Gigabyte GA-P55-UD6 motherboard lead with 23931 points. Next is the 2.66GHz Intel Core i7-920 for 22343 points, trailing behind 7%.

The memory tests are included for illustration, since the system memory bandwidth offers a very minor impact on gaming performance and real-world experience. Nevertheless, it's evident from the results that both read and write performance favor the dual-core Intel Core i7-860 over the triple-channel Core i7-920. The only time that triple-channel memory appears to benefit the system is during memory copy tests.
