GeForce 9500 GT 1GB GDDR3 vs Radeon HD 3470 512MB

Intro

The GeForce 9500 GT 1GB GDDR3 makes use of a 55 nm design. nVidia has set the core frequency at 550 MHz. The GDDR3 RAM is set to run at a speed of 800 MHz on this specific card. It features 32 SPUs as well as 16 TAUs and 8 ROPs.

Compare those specifications to the Radeon HD 3470 512MB, which has a clock frequency of 800 MHz and a GDDR3 memory speed of 950 MHz. It also features a 128-bit bus, and uses a 55 nm design. It features 40(8x5) SPUs, 4 Texture Address Units, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon HD 3470 512MB should in theory perform a little bit faster than the GeForce 9500 GT 1GB GDDR3 in general. (explain)

Radeon HD 3470 512MB 30400 MB/sec
GeForce 9500 GT 1GB GDDR3 25600 MB/sec
Difference: 4800 (19%)

Texel Rate

The GeForce 9500 GT 1GB GDDR3 should be quite a bit (approximately 175%) more effective at texture filtering than the Radeon HD 3470 512MB. (explain)

GeForce 9500 GT 1GB GDDR3 8800 Mtexels/sec
Radeon HD 3470 512MB 3200 Mtexels/sec
Difference: 5600 (175%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce 9500 GT 1GB GDDR3 is the winner, by far. (explain)

GeForce 9500 GT 1GB GDDR3 4400 Mpixels/sec
Radeon HD 3470 512MB 3200 Mpixels/sec
Difference: 1200 (38%)

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 information (measured in MB per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total texture units by the core clock 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 processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
