GeForce GTS 150 vs GeForce GTX 480

Intro

Compare all that to the GeForce GTX 480, which has core speeds of 700 MHz on the GPU, and 924 MHz on the 1536 MB of GDDR5 memory. It features 480 SPUs as well as 60 TAUs and 48 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTS 150		141 Watts
GeForce GTX 480		250 Watts
	Difference: 109 Watts (77%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 480 should be 454% quicker than the GeForce GTS 150 in general, because of its greater data rate. (explain)

GeForce GTX 480		177408 MB/sec
GeForce GTS 150		32000 MB/sec
	Difference: 145408 (454%)

Texel Rate

The GeForce GTS 150 will be a little bit (approximately 13%) more effective at anisotropic filtering than the GeForce GTX 480. (explain)

GeForce GTS 150		47360 Mtexels/sec
GeForce GTX 480		42000 Mtexels/sec
	Difference: 5360 (13%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 480 is superior to the GeForce GTS 150, and very much so. (explain)

GeForce GTX 480		33600 Mpixels/sec
GeForce GTS 150		11840 Mpixels/sec
	Difference: 21760 (184%)

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 (counted in megabytes per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 applied in one second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out 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 filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
