GeForce GT 430 (OEM) vs Radeon HD 6450 (OEM) 1GB

Intro

The GeForce GT 430 (OEM) has a clock speed of 700 MHz and a GDDR3 memory speed of 900 MHz. It also makes use of a 128-bit bus, and uses a 40 nm design. It is made up of 96 SPUs, 16 Texture Address Units, and 4 ROPs.

Compare all of that to the Radeon HD 6450 (OEM) 1GB, which features a clock speed of 750 MHz and a GDDR5 memory speed of 900 MHz. It also uses a 64-bit bus, and uses a 40 nm design. It is made up of 160 SPUs, 8 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 6450 (OEM) 1GB 31 Watts
GeForce GT 430 (OEM) 60 Watts
Difference: 29 Watts (94%)

Memory Bandwidth

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

Texel Rate

The GeForce GT 430 (OEM) will be much (approximately 87%) more effective at anisotropic filtering than the Radeon HD 6450 (OEM) 1GB. (explain)

GeForce GT 430 (OEM) 11200 Mtexels/sec
Radeon HD 6450 (OEM) 1GB 6000 Mtexels/sec
Difference: 5200 (87%)

Pixel Rate

The Radeon HD 6450 (OEM) 1GB should be a bit (approximately 7%) more effective at anti-aliasing than the GeForce GT 430 (OEM), and should be able to handle higher resolutions more effectively. (explain)

Radeon HD 6450 (OEM) 1GB 3000 Mpixels/sec
GeForce GT 430 (OEM) 2800 Mpixels/sec
Difference: 200 (7%)

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 maximum amount of data (in units of megabytes per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
