GeForce 9600 GT 512MB vs GeForce 9800 GTX+

Intro

The GeForce 9600 GT 512MB comes with a GPU clock speed of 650 MHz, and the 512 MB of GDDR3 RAM is set to run at 900 MHz through a 256-bit bus. It also is comprised of 64 Stream Processors, 32 TAUs, and 16 Raster Operation Units.

Compare all of that to the GeForce 9800 GTX+, which makes use of a 55 nm design. nVidia has set the core speed at 738 MHz. The GDDR3 RAM runs at a speed of 1100 MHz on this model. It features 128 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9600 GT 512MB 95 Watts
GeForce 9800 GTX+ 145 Watts
Difference: 50 Watts (53%)

Memory Bandwidth

In theory, the GeForce 9800 GTX+ is 22% faster than the GeForce 9600 GT 512MB in general, because of its greater bandwidth. (explain)

GeForce 9800 GTX+ 70400 MB/sec
GeForce 9600 GT 512MB 57600 MB/sec
Difference: 12800 (22%)

Texel Rate

The GeForce 9800 GTX+ should be a lot (about 127%) better at texture filtering than the GeForce 9600 GT 512MB. (explain)

GeForce 9800 GTX+ 47232 Mtexels/sec
GeForce 9600 GT 512MB 20800 Mtexels/sec
Difference: 26432 (127%)

Pixel Rate

The GeForce 9800 GTX+ should be a bit (more or less 14%) better at full screen anti-aliasing than the GeForce 9600 GT 512MB, and also will be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce 9800 GTX+ 11808 Mpixels/sec
GeForce 9600 GT 512MB 10400 Mpixels/sec
Difference: 1408 (14%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
