The GeForce GTX 970M should be a lot (more or less 85%) more effective at texture filtering than the Radeon R7 250X. (explain)

GeForce GTX 970M		73920 Mtexels/sec
Radeon R7 250X		40000 Mtexels/sec
	Difference: 33920 (85%)

Pixel Rate

The GeForce GTX 970M will be quite a bit (approximately 177%) more effective at anti-aliasing than the Radeon R7 250X, and also will be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 970M		44352 Mpixels/sec
Radeon R7 250X		16000 Mpixels/sec
	Difference: 28352 (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: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 amount of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
