Performance was a different story altogether. With a level playing field, using much of the same components, the Intel X6800 pulled ahead of the AMD FX62. Some of the performance advantage can be attributed to the fact that the X6800 runs at 2.93GHz, while the FX62 runs at 2.8GHz. Also, the FX62 is based upon a 90-nanometer design, while the X6800 uses a 65-nanometer design. The AMD FX62 earned an overall Passmark score of 670.5, while the Intel X6800 scored 925.2 overall. The overall score is based on all components in the system, including hard-drive speed and 3-D graphics performance.
With the systems configured as close to equal as possible, Intel outpaced AMD by almost 28 percent. To narrow down where the CPU's strengths and weaknesses are, Test Center engineers dove a little further into the tests to look at individual benchmarks. For example, the X6800 scored a 261.5 for integer math, while the FX62 scored a 172.6.
Another test showed that the Intel X6800 scored a 1,351.6 for CPU image rotation, while the AMD FX62 scored 765.3. As Test Center engineers delved even further, it was clear that Intel had taken a lead in performance, but that lead varied based on the individual tests.
While Intel has nailed the performance and power consumption benchmarks, surpassing AMD, there is still much more to a CPU that just plain performance. With that in mind, Intel has continued its commitment to virtualization with the inclusion of on-chip support. The company also has added on-chip virus protection with an execute bit disable function. Other enhancements include on-chip management capabilities and speed control technologies. All of the elements that Intel has included should help solution providers derive additional service revenue from Intel's platform, once the software becomes available to leverage those features. AMD has been no slouch in those areas either. The chip maker's new AM2-based processors also include antivirus and hardware virtualization support.
With all of the chips on the table, so to speak, Intel has pulled ahead in the desktop market by providing a faster, cheaper CPU than the competition. But that victory may be shortlived. AMD can quickly rebalance the scales by increasing clock speeds and lowering prices.
What's more, several system builders have turned to overclocking to boost the speed of AMD's processors, which very well could bring performance on a par with Intel.
One thing is certain, however: Intel's re-emergence as a performance leader will fuel a new performance war on the desktop, with pricing and availability being the primary weapons used.
The real challenge ahead for both vendors and for the channel alike is generating the need for these advanced technologies on today's corporate desktops.
