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 posesses.

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.

The NVIDIA ION platform, with a soldiered-in Intel Atom 330 dual-core processor, offered the best Queen performance of the bunch. The ASUS Eee PC 1000HE uses a single-core Intel Atom N280 processor, which rendered 57% less performance than the ION's 330. Even with the larger cache, the Dell Inspiron 6400's 1.66 GHz Intel Core Duo 2300 still fell behind the Atom 330 by almost 10%. But that's only CPU Queen...

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

The Eee PC's Atom N280 scored 2294 in the CPU PhotoWorxx test, with the ION's N330 raising the score nearly 70% to 3882. The Dell Inspiron's Intel Core Duo 2300 performed 35% better than the ION's N330 CPU with 5253.

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. The Eee PC's Atom N280 scored 8004 in the CPU Zip Library test, with the ION's N330 improving that score by 111% to 16845. The Dell Inspiron's Intel Core Duo 2300 performed only 17% better than the ION's N330 CPU with 19766.

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. In the AES testing, the Eee PC's N280 offered a mere 1909 points, with the ION's N330 processor scoring 3677 for a 93% improvement. The Intel Core Duo 2300 scored 5882 points, offering a 60% lead over the N330.

Intel Atom Processors

In the chart assembled below, Benchmark Reviews has organized the various Intel Atom processors released as of July 2009 for comparison. The NVIDIA ION is the only platform which supports EM64T instructions, for 64-bit Operating System compatibility, a feature that will prove invaluable with the upcoming Microsoft Windows 7 O/S release.
