GeForce GT 130 vs GeForce GTX 465

Intro

Compare those specifications to the GeForce GTX 465, which makes use of a 40 nm design. nVidia has set the core frequency at 607 MHz. The GDDR5 memory is set to run at a speed of 802 MHz on this particular card. It features 352 SPUs as well as 44 TAUs and 32 ROPs.

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

Pixel Rate

The GeForce GTX 465 is quite a bit (approximately 143%) better at full screen anti-aliasing than the GeForce GT 130, and will be capable of handling higher screen resolutions better. (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 max amount of data (measured in MB per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the 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 could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka 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, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
