GeForce GT 430 vs Radeon HD 4670 1GB

Intro

Compare those specs to the Radeon HD 4670 1GB, which makes use of a 55 nm design. AMD has set the core frequency at 750 MHz. The GDDR4/GDDR3/DDR3/DDR2 memory works at a frequency of 1100 MHz on this specific model. It features 320(64x5) SPUs as well as 32 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 430		60 Watts
Radeon HD 4670 1GB		70 Watts
	Difference: 10 Watts (17%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 4670 1GB should be 22% faster than the GeForce GT 430 in general, due to its higher data rate. (explain)

Radeon HD 4670 1GB		35200 MB/sec
GeForce GT 430		28800 MB/sec
	Difference: 6400 (22%)

Texel Rate

The Radeon HD 4670 1GB should be quite a bit (about 114%) better at texture filtering than the GeForce GT 430. (explain)

Radeon HD 4670 1GB		24000 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 12800 (114%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon HD 4670 1GB is superior to the GeForce GT 430, and very much so. (explain)

Radeon HD 4670 1GB		6000 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 3200 (114%)

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.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 can be applied in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip 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 number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
