GeForce GTS 250 1GB vs Radeon R7 M260X

Intro

Compare all that to the Radeon R7 M260X, which comes with GPU core speed of 825 MHz, and 2048 MB of GDDR5 memory set to run at 1000 MHz through a 128-bit bus. It also features 384 Stream Processors, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTS 250 1GB should be 10% quicker than the Radeon R7 M260X in general, because of its higher bandwidth. (explain)

GeForce GTS 250 1GB		70400 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 6400 (10%)

Texel Rate

The GeForce GTS 250 1GB is much (more or less 139%) more effective at AF than the Radeon R7 M260X. (explain)

GeForce GTS 250 1GB		47232 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 27432 (139%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTS 250 1GB is a better choice, by far. (explain)

GeForce GTS 250 1GB		11808 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 5208 (79%)

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 transported across the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core 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 also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
