GeForce 9500 GT 512MB GDDR3 vs GeForce 9600 GT 1GB

Intro

The GeForce 9500 GT 512MB GDDR3 features a clock frequency of 550 MHz and a GDDR3 memory speed of 800 MHz. It also makes use of a 128-bit memory bus, and makes use of a 55 nm design. It is made up of 32 SPUs, 16 TAUs, and 8 ROPs.

Compare those specifications to the GeForce 9600 GT 1GB, which features a GPU core clock speed of 650 MHz, and 1024 MB of GDDR3 RAM set to run at 900 MHz through a 256-bit bus. It also is made up of 64 Stream Processors, 32 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9500 GT 512MB GDDR3 50 Watts
GeForce 9600 GT 1GB 95 Watts
Difference: 45 Watts (90%)

Memory Bandwidth

Theoretically speaking, the GeForce 9600 GT 1GB is 125% quicker than the GeForce 9500 GT 512MB GDDR3 in general, because of its higher bandwidth. (explain)

GeForce 9600 GT 1GB 57600 MB/sec
GeForce 9500 GT 512MB GDDR3 25600 MB/sec
Difference: 32000 (125%)

Texel Rate

The GeForce 9600 GT 1GB is quite a bit (about 136%) better at AF than the GeForce 9500 GT 512MB GDDR3. (explain)

GeForce 9600 GT 1GB 20800 Mtexels/sec
GeForce 9500 GT 512MB GDDR3 8800 Mtexels/sec
Difference: 12000 (136%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce 9600 GT 1GB is superior to the GeForce 9500 GT 512MB GDDR3, and very much so. (explain)

GeForce 9600 GT 1GB 10400 Mpixels/sec
GeForce 9500 GT 512MB GDDR3 4400 Mpixels/sec
Difference: 6000 (136%)

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 max amount of data (in units of MB per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
