GeForce GT 430 (OEM) vs GeForce GTX 970

Intro

Compare all that to the GeForce GTX 970, which has a clock speed of 1050 MHz and a GDDR5 memory frequency of 1750 MHz. It also makes use of a 256-bit memory bus, and uses a 28 nm design. It features 1664 SPUs, 104 Texture Address Units, and 64 Raster Operation Units.

GeForce GT 430 (OEM)		28800 MB/sec
	Difference: 195200 (678%)

Texel Rate

The GeForce GTX 970 is quite a bit (more or less 875%) better at texture filtering than the GeForce GT 430 (OEM). (explain)

GeForce GTX 970		109200 Mtexels/sec
GeForce GT 430 (OEM)		11200 Mtexels/sec
	Difference: 98000 (875%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 970 is superior to the GeForce GT 430 (OEM), by a large margin. (explain)

GeForce GTX 970		67200 Mpixels/sec
GeForce GT 430 (OEM)		2800 Mpixels/sec
	Difference: 64400 (2300%)

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 calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it should 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 number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

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