Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1050 Ti		75 Watts
GeForce GTS 250 1GB		145 Watts
	Difference: 70 Watts (93%)

Memory Bandwidth

In theory, the GeForce GTX 1050 Ti will be 63% quicker than the GeForce GTS 250 1GB in general, due to its higher bandwidth. (explain)

GeForce GTX 1050 Ti		114688 MB/sec
GeForce GTS 250 1GB		70400 MB/sec
	Difference: 44288 (63%)

Texel Rate

The GeForce GTX 1050 Ti should be a lot (more or less 31%) more effective at anisotropic filtering than the GeForce GTS 250 1GB. (explain)

GeForce GTX 1050 Ti		61920 Mtexels/sec
GeForce GTS 250 1GB		47232 Mtexels/sec
	Difference: 14688 (31%)

Pixel Rate

The GeForce GTX 1050 Ti should be much (more or less 250%) more effective at anti-aliasing than the GeForce GTS 250 1GB, and will be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GTX 1050 Ti		41280 Mpixels/sec
GeForce GTS 250 1GB		11808 Mpixels/sec
	Difference: 29472 (250%)

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 max amount of information (measured in MB per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called 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 memory bandwidth is, the lower the ability to reach the max fill rate.
