GeForce GT 130 vs GeForce GTX 465

Intro

Compare those specifications to the GeForce GTX 465, which comes with a core clock frequency of 607 MHz and a GDDR5 memory frequency of 802 MHz. It also uses a 256-bit memory bus, and makes use of a 40 nm design. It is made up of 352 SPUs, 44 Texture Address Units, and 32 Raster Operation Units.

GeForce GT 130		12000 MB/sec
	Difference: 90592 (755%)

Texel Rate

The GeForce GTX 465 is much (more or less 123%) faster with regards to texture filtering than the GeForce GT 130. (explain)

GeForce GTX 465		26708 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 14708 (123%)

Pixel Rate

The GeForce GTX 465 will be quite a bit (about 143%) more effective at anti-aliasing than the GeForce GT 130, and will be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 465		19424 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 11424 (143%)

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 data (in units of megabytes per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
