Sapphire HD 2900 XT
Overclocking
Published: 9th July 2007 | Source: Sapphire | Price: |
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.

As always, nice review Kempez!

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 results
But

But a question, would this be a good upgrade from my x1900xt or should i go for a 2600xt? I am in two minds, as i dont really play a lot of games. But i do run two 1600x1200 monitors, and would like to be able to do dual screen with dx3d apps.
Or would a 8800GTS 640mb be better, given the price differences between them.

Tremendous review Kemp. I wonder why an 8 pin pci-e thingy isn`t in the bundle ? Seems strange to adopt a personalized connection type and not equip the average user with the means to use it.
That aside, bundle scores very nicely - tbh other manufacturers can learn a whole lot from this. Users love `free` stuff, and when it`s closely associated with the product too it`s great. Jeez a user would be happy with an XL "I score with Ati" shirt folded at the bottom of the box
Slightly off topic perhaps, but I see the Oblivion scores are silly-high in comparison with a 8800GTS... leads me to think if the game was heavily dev`d around an Ati engine. Would answer a few questions tbh. I can`t remember whether it boasts a card manuf when u run it.
Over all tho, I think it turned out as u may have previously thought, a good solid competitor for an 8800GTS. And it seems if u`r a really big Oblivion fan, u should seriously consider it.

Nice review but I think the comment about the "needing the extra 2 pins" was unnecessary. If you take a look @ the rear of your 8800GTX, you'll notice there is in fact a 6 pin and an 8 pin. NVIDIA chose to only solder on 6 of those 8 pins though. ATi could've done the same thing, you don't need 8 pins. ATi's Overdrive unlocks when you use an 8 pin and a 6 pin, but some people @ XS have discovered you can use two 6 pins and short the remaining 2 with a paperclip and Overdrive unlocks 
This I know, what I am questioning is why did ATI choose to include this? And why have they chosed not to unlock overdrive if you dont use the 6 PIN. Normal users won't be sticking paperclips into graphics cards and why the hell should they?
I am not just catering for the knowledgable enthusiasts in the reviews, it has to be everyone tbh

long review 
On the quake4 test. Did you do a timedemo
the results seem a bit 'wild'
All of the fps results are a bit wierd how do you get the avg fps etc?
edit: Once again I did three two minute runs on Quake 4 on each card and took the average of all my readings from these.
Sounds like a FRAPS type job?
The oblivion benchmark? is quite interesting.
On the hardware side, the cooler is quite nice
Shame about it being noisy
I thought the review was excellent. I really liked the beginning with the hardware images and little bits of info like the fan being noisy etc
I would be interested to see the HDMI capabilities of the card

Ye I use FRAPS to record FPS and play a manual run through of the game. Not sure why you say "wild", tis just min, max and average FPS. I know it works well cause the FPS stay the same every time and comparing two similar cards gets similar results. Some cards handle games well staying very steady, some really fluctuate ate certain points. That's where my impressions of the game come in so I can say if it was smooth or not (not just let the graphs do the talking)
Ta mate
I would have tested HDMI but I don't have an HDMI TV/Monitor (yet). Still, I know HDCP works well

There is a flaw in the review and nvidia cards were in disadvantage ..
"Both nVidia cards are using the nVidia !!! 97.92 !!! Forceware drivers.
The ATI card was installed with the Catalyst Control Center 7.6's."
The latest oficial is 158.22 and the latest beta is 163 ... Can the reviewer repeat the tests with latest official if not beta drivers...I hate nvidia very much but the reviews must be fair..
Latest drivers VS latest drivers
7.6 official VS 158.22 official

The review clearly states that these results were taken from a previous review which is the reason for the older drivers.
Yes there would perhaps be a difference, but not to the extent it would skew the results.
I no longer have the 8800 GTS's as they are back with the manufacturers.

Ya .. sorry..I forgot that the review states that thing.
Hello Kempez.After 7.8 will be released is any chance to update the review.The AA performance has been improved radically.
I no longer have a 2900XT, and unfortunately I can't redo each review after every driver release, I have enough trouble reviewing the new stuff that comes in!

Trouble is this isn't when the graphics cards companies want them done, and we kind of have to live by their schedule I'm afraid
CSS Valid
Sorry about that
Here we go
Enjoy
