Sapphire HD 2900 XT

Overclocking

Overclocking

Overclocking on the nVidia cards was performed using Rivatuner Release 2. Overclocking on the HD 2900 XT was performed using the AMD GPU Overclocking Tool. Again note that I am only using 2 x 6 PIN PCI-e power dongles and not a 6 PIN and an 8 PIN PCI-e power dongle as advised by AMD/ATI.

A test run of 3DMark06 was performed after the overclock to verify stability and also if the OC was worth the time.

Note that no hard or soft mods were performed on the card apart from setting the higher clocks.

Results

As you can see the Sapphire HD 2900 XT performed very well whilst my little bout of overclocking achieving 860MHz on the core and 900MHz on the memory. That's a nice little OC of 110MHz on the core and 75MHz on the memory.

I ran a 3DMark and here's what we get:

Not too shabby and certainly shows the HD 2900 XT as a decent overclocker, if you can stand the fan noise. Perhaps some more exciting forms of cooling would let you push that little bit further. Although the HD 2900 XT fell short of what I could achieve on the 8800 cards, the overclocking on the HD 2900 XT seemed to affect the 3DMark score quite a lot more.

I heard a crossfire setup of those. Man oh man hecka loud! If ATI sorted their size/power/noise issue, then I'd have definitely considered an HD2900XT.Quote

Not a fan on the sandwich heatsink. The 8800 Blocks are expensive enough, the 2900s are going too need even more copper = higher price again. Same goes for after-market air coolers.

But at the oblivion resultsQuote
