GeForce GTX 960M vs Radeon R7 250X 2GB

Intro

Compare all that to the Radeon R7 250X 2GB, which has GPU clock speed of 1000 MHz, and 2048 MB of GDDR5 memory set to run at 1125 MHz through a 128-bit bus. It also is comprised of 640 Stream Processors, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 960M		65 Watts
Radeon R7 250X 2GB		95 Watts
	Difference: 30 Watts (46%)

Memory Bandwidth

Theoretically speaking, the Radeon R7 250X 2GB will be 13% faster than the GeForce GTX 960M overall, due to its higher data rate. (explain)

Radeon R7 250X 2GB		72000 MB/sec
GeForce GTX 960M		64000 MB/sec
	Difference: 8000 (13%)

Texel Rate

The GeForce GTX 960M will be just a bit (more or less 10%) more effective at texture filtering than the Radeon R7 250X 2GB. (explain)

GeForce GTX 960M		43840 Mtexels/sec
Radeon R7 250X 2GB		40000 Mtexels/sec
	Difference: 3840 (10%)

Pixel Rate

The GeForce GTX 960M is a small bit (more or less 10%) better at AA than the Radeon R7 250X 2GB, and should be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 960M		17536 Mpixels/sec
Radeon R7 250X 2GB		16000 Mpixels/sec
	Difference: 1536 (10%)

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 (counted in MB per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once 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 high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs 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 rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
