GeForce GTS 150 vs GeForce GTX 1050

Intro

Compare that to the GeForce GTX 1050, which has a GPU core clock speed of 1354 MHz, and 2048 MB of GDDR5 RAM set to run at 1750 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 Texture Address Units, and 32 ROPs.

The GeForce GTX 1050 is a bit (about 14%) more effective at texture filtering than the GeForce GTS 150. (explain)

GeForce GTX 1050		54160 Mtexels/sec
GeForce GTS 150		47360 Mtexels/sec
	Difference: 6800 (14%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 1050 is a better choice, by a large margin. (explain)

GeForce GTX 1050		43328 Mpixels/sec
GeForce GTS 150		11840 Mpixels/sec
	Difference: 31488 (266%)

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 (in units of megabytes per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
