GeForce GTS and GTX both have some major differences and they all range around the performance side of things. Apart from the normal bump in core and memory, there are a few other key changes that differentiate the cards from each other.
Steam Processors on the 8800GTS come in at 96 while the more expensive 8800GTX gets quite a bump up to 128. The core clock on the GTX is bumped by 75MHz giving it a total of 575MHz compared to 500MHz found on the GTS. Other MHz bumps include the memory going from 1200MHz DDR on the GTS to 1350MHz DDR on the GTX along with the shader clock also getting a nice increase from 800MHz to 900MHz.
The GTX comes with a 384-bit memory bus compared to the 320-bit memory bus found on the GTS. In turn this gives us some weird memory numbers and with the higher bus found on the GTX we get 768MB of memory compared to 640MB.
From a pure numbers gain the overall bandwidth is increased in speeds and interface - the GTX gives us a memory bandwidth of 86.4GB/s and a texture fill rate of 36.8billion/s compared to the GTS which comes in at 64GB/s and 24billlion/s.
A few more other key aspects that are to be noted is that the overall length of the 8800GTX is greater when compared to the GTS and two PCI E connectors are used on the new top dog. We also have two SLI connectors on top of the 8800GTX - the general word that is getting around is that this will be used for tri SLI so you can have some absolute monster power.
From a supported perspective both cards have the support for HDCP, DX10, Quantum effects, Lumenex engine and other G80 dependent technologies which we looked at in our review of the MSI GeForce 8800GTS.
