GeForce GTS 150 vs GeForce GTX 460 SE

Intro

Compare all of that to the GeForce GTX 460 SE, which features core speeds of 650 MHz on the GPU, and 850 MHz on the 1024 MB of GDDR5 memory. It features 288 SPUs as well as 48 Texture Address Units and 32 ROPs.

GeForce GTS 150		141 Watts
GeForce GTX 460 SE		150 Watts
	Difference: 9 Watts (6%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 SE should perform a lot faster than the GeForce GTS 150 overall. (explain)

GeForce GTX 460 SE		108800 MB/sec
GeForce GTS 150		32000 MB/sec
	Difference: 76800 (240%)

Texel Rate

The GeForce GTS 150 is much (approximately 52%) more effective at texture filtering than the GeForce GTX 460 SE. (explain)

GeForce GTS 150		47360 Mtexels/sec
GeForce GTX 460 SE		31200 Mtexels/sec
	Difference: 16160 (52%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 460 SE is a better choice, by far. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
GeForce GTS 150		11840 Mpixels/sec
	Difference: 8960 (76%)

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 largest amount of data (counted in MB per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of 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 the texel rate, 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 maximum amount of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel 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 potential to get to the maximum fill rate.
