GeForce GT 430 vs GeForce GTX 260 Core 216

Intro

Compare all of that to the GeForce GTX 260 Core 216, which features GPU core speed of 576 MHz, and 896 MB of GDDR3 RAM set to run at 999 MHz through a 448-bit bus. It also is comprised of 216 SPUs, 72 Texture Address Units, and 28 Raster Operation Units.

GeForce GTX 260 Core 216		111888 MB/sec
GeForce GT 430		28800 MB/sec
	Difference: 83088 (289%)

Texel Rate

The GeForce GTX 260 Core 216 will be much (approximately 270%) more effective at AF than the GeForce GT 430. (explain)

GeForce GTX 260 Core 216		41472 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 30272 (270%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 260 Core 216 is the winner, by a large margin. (explain)

GeForce GTX 260 Core 216		16128 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 13328 (476%)

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 data (in units of megabytes per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
