GeForce GT 130 vs GeForce GTX 460 SE

Intro

Compare all of that to the GeForce GTX 460 SE, which uses a 40 nm design. nVidia has clocked the core speed at 650 MHz. The GDDR5 RAM works at a speed of 850 MHz on this card. It features 288 SPUs along with 48 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 130		75 Watts
GeForce GTX 460 SE		150 Watts
	Difference: 75 Watts (100%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 SE should perform much faster than the GeForce GT 130 in general. (explain)

GeForce GTX 460 SE		108800 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 96800 (807%)

Texel Rate

The GeForce GTX 460 SE is much (more or less 160%) more effective at AF than the GeForce GT 130. (explain)

GeForce GTX 460 SE		31200 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 19200 (160%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 460 SE is the winner, by far. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 12800 (160%)

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 max amount of data (counted in MB per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it must 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, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. 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 many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
