The 9800GTX+ is a die shrunk version of the 9800GTX. In other words, the manufacturing process has been reduced from 65nm to 55nm. Like the 9800GTX, the 9800GTX+ is built off of nVidia's highly popular G92 architecture. The heatsink and fan shroud carries over to the 9800GTX+ from the 9800GTX as well. However, the GPU core and shader clocks have been increased 65MHz and 144MHz respectively.
The connection end of the 9800GTX+ has two DVI ports, a single TV-out port and a power indicator light. When the card has sufficient power the light blinks upon booting. The other end of the 9800GTX+ has a large opening that functions as a vent for the cooling fan.
There are two connections for SLI bridges on the 9800GTX+. This feature would allow a potential three way SLI configuration. Also, two PCI-E power connectors are required to power up the 9800GTX+. The small connection between the power connectors and the SLI bridges is for S/PDIF audio. This connection allows digital audio to travel through the video card and out through an HDMI capable. Use of an HDMI adapter is necessary to use this feature.
Never have I seen a heatsink so securely fastened to a PCB. There are 14 spring loaded screws and three normal screws pinning the 9800GTX+ together. The 9800GTX+ stock heatsink is a huge array of aluminum and copper. Every important component on the PCB appears to be cooled by the heatsink
After removing the heatsink and shroud from the video card we get a good look at nVidia's choice of component placement on the PCB. The G92 core is ringed by eight memory modules. The complex power circuitry is located below the two PCI-E power connectors on the right side of the PCB. The thermal paste is applied excessively, which is typical of most video cards. I am sure the GPU core temperatures could benefit from reapplication of thermal paste.
The Palit 9800GTX+ is built around the ubiquitous G92 core, which has been die shrunk to a 55nm manufacturing process. Memory for the 9800GTX+ has been sourced from Samsung. Interestingly, although the 9800GTX+ memory comes rated at 1100MHz, this particular GDDR3 memory is rated at 1200MHz.
Let's take a look at the drivers and programs that Palit has provided with the 9800GTX+.
