GeForce GTS 150 vs GeForce GTX 470

Intro

The GeForce GTS 150 features a GPU core clock speed of 740 MHz, and the 1024 MB of GDDR3 memory is set to run at 500 MHz through a 256-bit bus. It also is comprised of 128 Stream Processors, 64 TAUs, and 16 Raster Operation Units.

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

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

Memory Bandwidth

In theory, the GeForce GTX 470 is 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 should be quite a bit (approximately 39%) more effective at AF than the GeForce GTX 470. (explain)

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

Pixel Rate

The GeForce GTX 470 is much (about 105%) better at anti-aliasing than the GeForce GTS 150, and also will be able to handle higher resolutions while still performing well. (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.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of MB per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling 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 graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
