GeForce GTS 150 vs GeForce GTX 460

Intro

Compare all of that to the GeForce GTX 460, which features clock speeds of 675 MHz on the GPU, and 900 MHz on the 768 MB of GDDR5 memory. It features 336 SPUs as well as 56 TAUs and 24 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically, the GeForce GTX 460 should perform quite a bit faster than the GeForce GTS 150 overall. (explain)

GeForce GTX 460		86400 MB/sec
GeForce GTS 150		32000 MB/sec
	Difference: 54400 (170%)

Texel Rate

The GeForce GTS 150 is quite a bit (approximately 25%) more effective at texture filtering than the GeForce GTX 460. (explain)

GeForce GTS 150		47360 Mtexels/sec
GeForce GTX 460		37800 Mtexels/sec
	Difference: 9560 (25%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 460 is a better choice, by far. (explain)

GeForce GTX 460		16200 Mpixels/sec
GeForce GTS 150		11840 Mpixels/sec
	Difference: 4360 (37%)

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 maximum amount of data (in units of megabytes per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 applied per second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling 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 the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
