GeForce GT 430 vs GeForce GTS 450

Intro

Compare those specifications to the GeForce GTS 450, which has a clock speed of 783 MHz and a GDDR5 memory speed of 902 MHz. It also uses a 128-bit memory bus, and makes use of a 40 nm design. It is comprised of 192 SPUs, 32 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 430		60 Watts
GeForce GTS 450		106 Watts
	Difference: 46 Watts (77%)

Memory Bandwidth

Performance-wise, the GeForce GTS 450 should in theory be a lot better than the GeForce GT 430 in general. (explain)

GeForce GTS 450		57728 MB/sec
GeForce GT 430		28800 MB/sec
	Difference: 28928 (100%)

Texel Rate

The GeForce GTS 450 should be a lot (more or less 124%) better at texture filtering than the GeForce GT 430. (explain)

GeForce GTS 450		25056 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 13856 (124%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTS 450 is a better choice, and very much so. (explain)

GeForce GTS 450		12528 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 9728 (347%)

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 largest amount of information (measured in MB per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
