With the shrink in die things are supposed to be better all around with the 9800GTX+. Not only do you benefit from the higher clocks and less power consumption but in the case of this GPU you also get a non-reference heatsink. This still remains a dual slot configuration but the extra long cooler is dismissed somewhat shortening the length of the card. The older reference cooler that once exhausted out the back of the case is replaced by one that more compact and should perform much better with a well vented case.
All of the improvements of the 9800GTX lays underneath the new cooler of the 9800GTX+. All beginning with the smaller TSMC die which shrinks from 65nm to 55nm. This may not mean much in the beginning but at the end of the month when you receive the electricity bill the few cents saved is nice. But peformance is why we are here and why you are reading this article. The core clock of the Plus is up from the 645MHz of the old 9800GTX and 738MHz of the reference 9800GTX+ to 745MHz of the model we are reviewing today. We will be seeing more than a few frames increase with this new puppy. The memory clocks of 1100MHz is unchanged in this version. And for those folders out there the shaders are clocked at an incredible 1836MHz. This should get you some speedy PDD when GPU folding when coupled with the CUDA drivers.
Even with this being a non-reference video card the back of the adapter keeps the same layout of the original. Dual DVI connections are used for multi-display setups for a maximum resolution of 2560x1600. We have bragged often about Sapphire's 4xxx series card capable of supporting HDCP, well these 9800GTX's from Palit do also.
