GeForce GTS 150 vs GeForce GTX Titan Black

Intro

Compare that to the GeForce GTX Titan Black, which uses a 28 nm design. nVidia has set the core speed at 889 MHz. The GDDR5 RAM is set to run at a frequency of 1750 MHz on this specific card. It features 2880 SPUs as well as 240 TAUs and 48 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

As far as performance goes, the GeForce GTX Titan Black should in theory be quite a bit better than the GeForce GTS 150 overall. (explain)

GeForce GTX Titan Black		336000 MB/sec
GeForce GTS 150		32000 MB/sec
	Difference: 304000 (950%)

Texel Rate

The GeForce GTX Titan Black should be much (about 351%) better at texture filtering than the GeForce GTS 150. (explain)

GeForce GTX Titan Black		213360 Mtexels/sec
GeForce GTS 150		47360 Mtexels/sec
	Difference: 166000 (351%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX Titan Black is superior to the GeForce GTS 150, and very much so. (explain)

GeForce GTX Titan Black		42672 Mpixels/sec
GeForce GTS 150		11840 Mpixels/sec
	Difference: 30832 (260%)

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 information (in units of MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
