GeForce GT 430 vs GeForce GTX 560

Intro

Compare all of that to the GeForce GTX 560, which uses a 40 nm design. nVidia has clocked the core frequency at 810 MHz. The GDDR5 RAM is set to run at a frequency of 1001 MHz on this specific card. It features 336 SPUs as well as 56 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 430		60 Watts
GeForce GTX 560		150 Watts
	Difference: 90 Watts (150%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 560 should be a lot faster than the GeForce GT 430 in general. (explain)

GeForce GTX 560		128128 MB/sec
GeForce GT 430		28800 MB/sec
	Difference: 99328 (345%)

Texel Rate

The GeForce GTX 560 will be much (more or less 305%) better at AF than the GeForce GT 430. (explain)

GeForce GTX 560		45360 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 34160 (305%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 560 is a better choice, by a large margin. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 23120 (826%)

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: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of 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 per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
