About EVEREST Ultimate Edition

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.

CPU and FPU benchmarks

State of the art multi-threaded benchmark methods to measure performance of both old and brand new processors. References list to compare actual performance with other systems.

Memory benchmarking

Memory read and write speed, memory latency measurement to stress the memory and cache subsystem, including references list to compare actual performance with other systems.

The Asus Eee PC runs a Dothan core Celeron-M ULV processor rated at 900MHz; but downclocked to 630MHz (FSB is downclocked to 70MHz with multiplier of 6x). This allows some very modest cooling methods we've seen when we took apart the Asus Eee PC a few pages back -- and improved battery life -- but at the price of performance. Of course, the Asus Eee PC is never meant to be a performance machine anyways with very modest specifications -- and at this clock speed, the scores are reflected in our CPU and FPU performance tests with EVEREST 4.50.

At 70MHz FSB or 280MHz rated with QDR (Like all Intel processors from the last few years, there are four lanes connecting to theoretically quadruple the FSB), again we didn't expect astonishing performance. Generally speaking, these numbers were very acceptable in this form -- and we are benchmarking an Eee PC for low cost and portability, not a performance oriented system anyways. Just for references.

The implementation of an external memory controller, as well as low bandwidth between RAM and processor all contributed to relatively higher latency in the memory latency segment.

About HD Tach

HD Tach will test the sequential read, random access and interface burst speeds of your attached storage device (hard drive, flash drive, removable drive, etc). All drive technologies such as SCSI, IDE/ATA, 1394, USB, SATA and RAID are supported. Test results from HD Tach can be used to confirm manufacturer specs, analyze your system for proper performance, and compare your performance with others. HD Tach is very easy to use, quick, and presents data in easy to read graphs, including the ability to compare two storage devices on screen at the same time for easy analysis.

The Asus Eee PC uses an 4GB Silicon Motion SM223A flash SSD -- which performance generally very well in terms of operating system and program load times. Our HD Tach results show the Asus Eee PC's internal drive performance to obtain an average read speed of 30.4MB/s. While not necessarily impressive compared to even most PMR 5400RPM laptop hard disks, the latency is really good at 0.5ms random access.

However, the downsides of having this SSD is that it's extremely slow once you're going through a lot of small files or getting the drive to work with multiple streams of data access -- downloading and installing those 100 Windows XP Updates between SP2 and SP3 took two or three hours, not to mention that opening anything simple like 'My Computer' takes five minutes.

The ICH6 Southbridge supplied USB ports didn't perform particularly well; under Windows XP we recorded an average read speed of 16.4MB/s with 1.1ms access latency with our OCZ Rally2 Turbo 4GB USB flash drive -- our official record performance for the drive on our desktop Intel ICH9R supplied USB ports came in at 32.8MB/s -- exactly twice as fast as the USB performance on the Asus Eee PC.
