Sapphire PI-AM2RS780G Review

Testing:

To push Sapphire's PI-AM2RS780G mainboard, I wanted to throw everything at it that I could. The 780G market has been flooded by manufacturers, and we want to find the best board for the money. With that in mind, I want to be as thorough as possible, so I am going to run the tests first on the AMD Phenom 9600 "Black Box" processor using the IGP and Hybrid Graphics, and then again with the 8800GT to see the performance difference using each graphics type. I am then going to compare the Sapphire PI-AM2RS780G against two other 780G-based motherboards, all using the AMD Phenom 9600 "Black Box" CPU, to measure its performance compared to the competition. All hardware will be run at stock speeds, voltages, and timings to prevent any variables that might influence the results.

 

Testing Setup:

 

Comparison Motherboards:


As I mentioned before, this motherboard supports Hybrid CrossFire when paired with a compatible discrete graphics solution, like an ATI HD3400 series card. Here is a shot of the ATI Control Panel, Windows Device Manager, and GPU-Z showing the two video devices enabled in Hybrid CrossFire.

 

Overclocking:

Overclocked settings:

With the other 780G boards I was able to increase the multiplier of the Phenom 9600 "Black Box" Edition to 13.5x for a total of 2.70GHz, but no matter what I did, I could not get Sapphire's 780G to boot over 2.5GHz (200x12.5). I tried increasing the voltage to dangerous levels, and dropped the HT multiplier to no avail. Since I know the Phenom 9600 will do 200x12.5 on the other boards, I know that Sapphire's motherboard is the limiting factor. Therefore, all of the overclocked speeds will be capped at 2.5GHz, and those scores will be recorded.
