GeForce GTS 150 vs GeForce GTX 950

Intro

Compare all of that to the GeForce GTX 950, which has clock speeds of 1024 MHz on the GPU, and 1652 MHz on the 2048 MB of GDDR5 memory. It features 768 SPUs as well as 48 TAUs and 32 ROPs.

Memory Bandwidth

As far as performance goes, the GeForce GTX 950 should theoretically be much better than the GeForce GTS 150 overall. (explain)

GeForce GTX 950		105728 MB/sec
GeForce GTS 150		32000 MB/sec
	Difference: 73728 (230%)

Texel Rate

The GeForce GTX 950 will be a little bit (approximately 4%) faster with regards to texture filtering than the GeForce GTS 150. (explain)

GeForce GTX 950		49152 Mtexels/sec
GeForce GTS 150		47360 Mtexels/sec
	Difference: 1792 (4%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 950 is a better choice, and very much so. (explain)

GeForce GTX 950		32768 Mpixels/sec
GeForce GTS 150		11840 Mpixels/sec
	Difference: 20928 (177%)

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 information (in units of megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 can be applied in one second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, 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 most pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
