GeForce GTS 150 vs GeForce GTX 1050 Ti

Intro

Compare those specifications to the GeForce GTX 1050 Ti, which uses a 14 nm design. nVidia has set the core speed at 1290 MHz. The GDDR5 RAM runs at a speed of 1750 MHz on this particular model. It features 768 SPUs as well as 48 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1050 Ti		75 Watts
GeForce GTS 150		141 Watts
	Difference: 66 Watts (88%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1050 Ti will be 258% faster than the GeForce GTS 150 overall, because of its greater data rate. (explain)

GeForce GTX 1050 Ti		114688 MB/sec
GeForce GTS 150		32000 MB/sec
	Difference: 82688 (258%)

Texel Rate

The GeForce GTX 1050 Ti will be much (about 31%) more effective at anisotropic filtering than the GeForce GTS 150. (explain)

GeForce GTX 1050 Ti		61920 Mtexels/sec
GeForce GTS 150		47360 Mtexels/sec
	Difference: 14560 (31%)

Pixel Rate

The GeForce GTX 1050 Ti should be quite a bit (more or less 249%) better at FSAA than the GeForce GTS 150, and will be able to handle higher screen resolutions better. (explain)

GeForce GTX 1050 Ti		41280 Mpixels/sec
GeForce GTS 150		11840 Mpixels/sec
	Difference: 29440 (249%)

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 maximum amount of data (counted in megabytes per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, it must 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the 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 amount of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
