To see which architecture performs best Expreview clocked all four processors at 3GHz.
Here are the results:
|Crysis CPU benchmark||Intel E6850||Intel QX6850||Intel QX9650||AMD Phenom X4|
|Frequency||3GHz (333MHz x 9)||3GHz (333MHz x 9)||3GHz (333MHz x 9)||3GHz (200MHz x 15)|
|Timedemo Run 0||44.01||45.14||45.46||40.38|
|Timedemo Run 1||50.42||51.37||51.24||48.27|
|Timedemo Run 2||51.12||51.63||51.55||48.53|
|Timedemo Run 3||51.21||51.55||51.56||48.72|
In this benchmark the Phenom X4 doesn't really impress, in a clock-to-clock comparison to chip can't beat the Core 2 processors and most rumours indicate AMD isn't even planning to release a 3GHz Phenom X4 processor this year or in early 2008. If this benchmark is a good indication of the performance of the K10 it seems that AMD will need to agressively price their Phenom CPUs to compete with Intel.
