Nvidia GeForce 8800 GT graphics chip
Nvidia's bang-for-buck winner?
Review Nvidia’s new 'G92' graphics chip is based on the 'G80' used in the GTS, GTX and Ultra versions of the GeForce 8800, and is a die-shrink that moves from the part from its predecessors' 90nm fabrication process to 65nm.
There are other changes inside the chip, which gains the VP2 video engine and bitstream processor used in the junior members of the GeForce 8000 family. Fans of HD video won’t have to work their CPU quite so hard in future. Nvidia also tells us that the 8800 GT gains an AES128 encryption/decryption engine for HDCP content.

Thanks to the extra hardware, G92 contains more transistors than G80, with the count increasing from 681 million to 754 million.
Other new features include a move from PCI Express (PCIe) 1.1 to 2.0, and the adoption of HDCP for content copy-protection over dual-link DVI. If you have a socking great display, the dual-link connection can drive a resolution of 2560 x 1600.
In terms of the core speed, memory speed and Stream processors, the GT is positioned right between the current GTS and GTX models.
|8800 GTS||8800 GTS||8800 GTX||8800 Ultra||8800 GT||8800 GT|
|Memory||320MB GDDR 3||640MB GDDR 3||768MB GDDR 3||768MB GDDR 3||512MB GDDR 3||512MB GDDR 3|
The new GT core runs at 600MHz, which is faster than both the GTS and GTX. The GDDR 3 memory runs at the same 1800MHz as the GTX and there are 112 stream processors - more than the GTS, less than the GTX - which run at the same 1500MHz as the 8800 Ultra.

The one notable difference with 8800 GT is a change in the memory controller. The GTS has a 320-bit controller for the 320MB or 640MB of GDDR 3 memory, while GTX uses a 384-bit controller for its 768MB of memory, but the GT employs a 256-bit controller for 512MB of memory. Despite the faster memory speed used by the GT the memory bandwidth is narrow than it is on the GTS, significantly slower than the GTX and half that of the Ultra.
All well & good, however...
...no buggers got 'em in stock anymore. Fair enough releasing something pretty, would be handy if they could actually come out in decent numbers though FFS.
Boy thank you. You saved me some bucks.
Beware Linux users
Currently there are no drivers for this card under linux. The Nvidia driver selector on their website will tell you that you can use version 100.14.19 or 100.14.23 - beta. This is NOT TRUE, they will not work.
Nvidia have said that they will release compatible drivers for this card as a top priority but there is no ETA...
I just found out the hard way...
