GeForce GT 130 vs GeForce GTX 465

Intro

Compare all of that to the GeForce GTX 465, which comes with core speeds of 607 MHz on the GPU, and 802 MHz on the 1024 MB of GDDR5 RAM. It features 352 SPUs along with 44 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 130		75 Watts
GeForce GTX 465		200 Watts
	Difference: 125 Watts (167%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 465 will be 755% quicker than the GeForce GT 130 overall, because of its higher bandwidth. (explain)

GeForce GTX 465		102592 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 90592 (755%)

Texel Rate

The GeForce GTX 465 is much (more or less 123%) more effective at AF 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 is quite a bit (about 143%) more effective at full screen anti-aliasing than the GeForce GT 130, and capable of handling higher resolutions more effectively. (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 maximum amount of data (measured in MB per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total number of texture units of the card by the core 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 one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record 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 - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
