here is a quick and dirty Phenom/Crysis clockspeed/NB speed study....
I used the benchnark tool found at Guru3D, the setup of the system has been documented elswhere, if you want a link to full system specs let me know (I posted that several pages back). In short, the data collected here was done on a Phenom 9850 BE + Asus M3AMVP-Deluxe + DDR2800 C4 + ATI Radeon 4870 X2 with catalyst 8.8 drivers (EDIT: oops, my bad... looks like the SPD is defaulting it to C5 on the DDR2). The benchmark was ran to focus on the CPU, 800x600, low quality settings. I ran at 2.5 GHz and NB of 2000 and 2400, then again at 3.0 GHz with NB of 2000 and 2400 MHz. The results (screen shots) and output are posted below:
9850BE@2.5 GHz, NB=2000 MHz ave = ~ 112-113 FPS
9850BE@2.5 GHz, NB=2400 MHz ave = ~ 115 FPS
9850BE@3.0 GHz, NB=2000 MHz ave = ~ 125 FPS
9850BE@3.0 GHz NB = 2400 Mhz ave = ~ 128
I have also attached the log/output below (this provides all the details that screen shots cannot capture).
For a 400 Mhz increase in NB speed, the increase in frame rate for this configuration is 2-3 FPS, the minimums are random, take note there is some texture loading occurring mid game as can be seen by the first run always being lower on the first loop. A 500 Mhz increase in core clock speed improves FPS by 10-15 FPS on average, gain in this configuration. Remember that this is running the GPU test in all low settings. I am looking into setting all the CPU related settings (physics quality and particle quality to high). Finally, a combination of 400 Mhz NB and 500 Mhz core clock will yield 15-16 FPS improvement which is > 10%.
I will turn my attention next to a 2.5 GHz clocked 9650 and 3.0 Ghz clock 9650....
