GeForce GT 430 vs Radeon HD 3470 512MB

Intro

The GeForce GT 430 comes with a core clock frequency of 700 MHz and a GDDR3 memory frequency of 900 MHz. It also features a 128-bit memory bus, and makes use of a 40 nm design. It features 96 SPUs, 16 Texture Address Units, and 4 ROPs.

Compare those specifications to the Radeon HD 3470 512MB, which features GPU clock speed of 800 MHz, and 512 MB of GDDR3 memory running at 950 MHz through a 128-bit bus. It also features 40(8x5) Stream Processors, 4 TAUs, and 4 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 3470 512MB should perform a little bit faster than the GeForce GT 430 in general. (explain)

Radeon HD 3470 512MB 30400 MB/sec
GeForce GT 430 28800 MB/sec
Difference: 1600 (6%)

Texel Rate

The GeForce GT 430 is quite a bit (about 250%) more effective at AF than the Radeon HD 3470 512MB. (explain)

GeForce GT 430 11200 Mtexels/sec
Radeon HD 3470 512MB 3200 Mtexels/sec
Difference: 8000 (250%)

Pixel Rate

The Radeon HD 3470 512MB should be a bit (approximately 14%) more effective at AA than the GeForce GT 430, and will be capable of handling higher resolutions without losing too much performance. (explain)

Radeon HD 3470 512MB 3200 Mpixels/sec
GeForce GT 430 2800 Mpixels/sec
Difference: 400 (14%)

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 information (measured in megabytes per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
