Right, it's always good to have a brief look at a product line merely based on prices to see and understand the dynamics without looking at technical specifications first. It establishes a good perspective of product positioning. Have a look:

• GeForce 8800 GTX - $599
• GeForce 8800 GTS - $449
• GeForce 8800 GTS  - $309 (320 MB)
• GeForce 7950 GT - $299
• GeForce 7900 GS - $199
• GeForce 7600 GT - $159
• GeForce 7600 GS - $129
• GeForce 7300 GPUs - <$99

Since not everyone can afford to cough up half their monthly salary to play games this is where the GeForce 8800 GTS surfaces. Fact is that the 640 MB product has been selling in rather unpleasant numbers. Targeted at 449 USD, people simply decided to invest more money and go for the flagship card, the GTX. So NVIDIA had to do something about that. It's goes something like this: the two most expensive and important items on a graphics card are the graphics chipset and the memory. You can understand that leaving the graphics core intact 100% yet saving money on the memory has a rather unusual and special effect. You'll get the RAW performance of the GPU, yet you'll be limited to play in uber-high resolutions or in instances where the GPU has to manage complex memory dependant operations (AA for example).

Core frequency then: Any GTS model will come with a 500 MHz core clock at standard (overclocked editions are obviously faster) and thus now will be available in a 640 and 320 MB version. The memory at standard is clocked at 800 (1600 effective) as well.

Other than that we'll now get to the Unified Shaders slash streaming processors (please read our reference 8800 GTS/GTX review if you want to learn about the new architecture). The sheer number of these units as you know has been cut down from 128 (GTX)  towards 96 shader cores for the GTS. Bare in mind though that the number of Shader processors (96) is exactly the same as on the 640 MB model as it is on this new 320 Mb model. So you have a 100% similar graphics core on this 320 Mb model, and that's like chocolate in a golden wrapper as everybody expected the number of shader processors to be downsized as well. Even the shader domain clock frequency is clocked 100% similar to the 640 MB model at 1200 MHz.

Since we are talking about a state of the art product series 8 product you can expect certain features for granted; the 320 Mb GTS is a HDCP compliant product, it has support for two high-res monitors with the help of Dual-Link DVI. Also the standard VIVO options including HDTV output are present. So this is a HD ready product in all  ways.

Some generic facts:

• All NVIDIA GeForce 8800 GTX and GeForce 8800 GTS-based graphics cards are HDCP capable.
• The GeForce 8 Series GPUs are not only the first shipping DirectX 10 GPUs, but they are also the reference GPUs for DirectX 10 API development and certification and are 100% DirectX 9 compatible.
• GeForce 8800 GPUs deliver full support for Shader Model 4.0.
• All graphics cards are being built by NVIDIAs contract manufacturer.
• All GeForce 8800 GPUs support NVIDIA SLI technology.
• The NVIDIA GeForce 8800 GTX has a 24 pixel per clock ROP. The GeForce 8800 GTS has a 20 pixel per clock ROP.
• GeForce 8800 GTX requires a minimum 450W or greater system power supply (with 12V current rating of 30A). GeForce 8800 GTS requires a minimum 400W or greater system power supply (with 12V current rating of 26A).

In the photo shoot we'll have a closer look at all three products and tell you a little about connectivity and also that memory mystery.

We'll be testing GeForce 8800 320 Mb GTS cards from two brands today. Let's have a look at what they have to offer precisely.
