GeForce 9500 GT DDR2 vs GeForce 9600 GSO 384MB

Intro

The GeForce 9500 GT DDR2 comes with a clock speed of 550 MHz and a DDR2 memory frequency of 500 MHz. It also uses a 128-bit memory bus, and makes use of a 65 nm design. It features 32 SPUs, 16 TAUs, and 8 ROPs.

Compare those specs to the GeForce 9600 GSO 384MB, which makes use of a 65 nm design. nVidia has set the core frequency at 550 MHz. The GDDR3 memory is set to run at a speed of 800 MHz on this model. It features 96 SPUs as well as 48 Texture Address Units and 12 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9500 GT DDR2 50 Watts
GeForce 9600 GSO 384MB 84 Watts
Difference: 34 Watts (68%)

Memory Bandwidth

Theoretically speaking, the GeForce 9600 GSO 384MB is 140% quicker than the GeForce 9500 GT DDR2 overall, due to its greater data rate. (explain)

GeForce 9600 GSO 384MB 38400 MB/sec
GeForce 9500 GT DDR2 16000 MB/sec
Difference: 22400 (140%)

Texel Rate

The GeForce 9600 GSO 384MB should be much (approximately 200%) more effective at anisotropic filtering than the GeForce 9500 GT DDR2. (explain)

GeForce 9600 GSO 384MB 26400 Mtexels/sec
GeForce 9500 GT DDR2 8800 Mtexels/sec
Difference: 17600 (200%)

Pixel Rate

The GeForce 9600 GSO 384MB should be quite a bit (more or less 50%) more effective at anti-aliasing than the GeForce 9500 GT DDR2, and will be able to handle higher screen resolutions more effectively. (explain)

GeForce 9600 GSO 384MB 6600 Mpixels/sec
GeForce 9500 GT DDR2 4400 Mpixels/sec
Difference: 2200 (50%)

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: Bandwidth is the max amount of data (in units of MB per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, 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 number of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
