GeForce 9500 GT 512MB GDDR3 vs GeForce GTX 570

Intro

The GeForce 9500 GT 512MB GDDR3 makes use of a 55 nm design. nVidia has clocked the core frequency at 550 MHz. The GDDR3 memory is set to run at a speed of 800 MHz on this model. It features 32 SPUs along with 16 Texture Address Units and 8 ROPs.

Compare all that to the GeForce GTX 570, which comes with core speeds of 732 MHz on the GPU, and 950 MHz on the 1280 MB of GDDR5 memory. It features 480 SPUs as well as 60 TAUs and 40 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9500 GT 512MB GDDR3 50 Watts
GeForce GTX 570 219 Watts
Difference: 169 Watts (338%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 570 will be 494% quicker than the GeForce 9500 GT 512MB GDDR3 in general, because of its higher data rate. (explain)

GeForce GTX 570 152000 MB/sec
GeForce 9500 GT 512MB GDDR3 25600 MB/sec
Difference: 126400 (494%)

Texel Rate

The GeForce GTX 570 should be a lot (more or less 399%) better at AF than the GeForce 9500 GT 512MB GDDR3. (explain)

GeForce GTX 570 43920 Mtexels/sec
GeForce 9500 GT 512MB GDDR3 8800 Mtexels/sec
Difference: 35120 (399%)

Pixel Rate

The GeForce GTX 570 is quite a bit (approximately 565%) better at anti-aliasing than the GeForce 9500 GT 512MB GDDR3, and also able to handle higher screen resolutions better. (explain)

GeForce GTX 570 29280 Mpixels/sec
GeForce 9500 GT 512MB GDDR3 4400 Mpixels/sec
Difference: 24880 (565%)

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 largest amount of data (measured in MB per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. 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 output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
