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

Intro

The GeForce 9500 GT 1GB GDDR3 has clock speeds of 550 MHz on the GPU, and 800 MHz on the 1024 MB of GDDR3 memory. It features 32 SPUs as well as 16 Texture Address Units and 8 ROPs.

Compare all that to the GeForce 9500 GT 512MB GDDR3, which comes with a core clock speed of 550 MHz and a GDDR3 memory frequency of 800 MHz. It also features a 128-bit memory bus, and makes use of a 55 nm design. It is comprised of 32 SPUs, 16 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Both cards have the exact same bandwidth, so in theory they should have the same performance. (explain)

Texel Rate

Both cards have the exact same texel fill rate, so in theory they should perform equally good at at anisotropic filtering. (explain)

Pixel Rate

Both cards have exactly the same pixel fill rate, so in theory they should be equally good at at AA, and be capable of handling the same resolutions. (explain)

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 information (counted in MB per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, 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 maximum amount of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core 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 also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
