GeForce GTS 150 vs GeForce GTX 470

Intro

Compare that to the GeForce GTX 470, which features core speeds of 607 MHz on the GPU, and 837 MHz on the 1280 MB of GDDR5 RAM. It features 448 SPUs as well as 56 TAUs and 40 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTS 150		141 Watts
GeForce GTX 470		215 Watts
	Difference: 74 Watts (52%)

Memory Bandwidth

In theory, the GeForce GTX 470 will be 319% quicker than the GeForce GTS 150 in general, because of its greater bandwidth. (explain)

GeForce GTX 470		133920 MB/sec
GeForce GTS 150		32000 MB/sec
	Difference: 101920 (319%)

Texel Rate

The GeForce GTS 150 is quite a bit (about 39%) more effective at texture filtering than the GeForce GTX 470. (explain)

GeForce GTS 150		47360 Mtexels/sec
GeForce GTX 470		33992 Mtexels/sec
	Difference: 13368 (39%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 470 is superior to the GeForce GTS 150, by a large margin. (explain)

GeForce GTX 470		24280 Mpixels/sec
GeForce GTS 150		11840 Mpixels/sec
	Difference: 12440 (105%)

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 (in units of megabytes per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. 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 amount of texture map elements (texels) that are processed in one second. This is worked out 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel 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 get to the maximum fill rate.
