GeForce 9500 GT DDR2 vs GeForce GT 310

Intro

The GeForce 9500 GT DDR2 comes with a core clock frequency of 550 MHz and a DDR2 memory frequency of 500 MHz. It also makes use of a 128-bit memory bus, and makes use of a 65 nm design. It is made up of 32 SPUs, 16 TAUs, and 8 Raster Operation Units.

Compare those specifications to the GeForce GT 310, which features a core clock frequency of 589 MHz and a DDR2 memory frequency of 1000 MHz. It also makes use of a 64-bit bus, and makes use of a 40 nm design. It features 16 SPUs, 8 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 310 31 Watts
GeForce 9500 GT DDR2 50 Watts
Difference: 19 Watts (61%)

Memory Bandwidth

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

Texel Rate

The GeForce 9500 GT DDR2 is quite a bit (approximately 87%) more effective at anisotropic filtering than the GeForce GT 310. (explain)

GeForce 9500 GT DDR2 8800 Mtexels/sec
GeForce GT 310 4712 Mtexels/sec
Difference: 4088 (87%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce 9500 GT DDR2 is superior to the GeForce GT 310, by far. (explain)

GeForce 9500 GT DDR2 4400 Mpixels/sec
GeForce GT 310 2356 Mpixels/sec
Difference: 2044 (87%)

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 (counted in MB per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
