Radeon R7 M260X vs Radeon R9 290

Intro

Compare that to the Radeon R9 290, which uses a 28 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 RAM works at a frequency of 1250 MHz on this particular model. It features 2560 SPUs along with 160 Texture Address Units and 64 Rasterization Operator Units.

Radeon R7 M260X		19800 Mtexels/sec
	Difference: 108200 (546%)

Pixel Rate

The Radeon R9 290 will be much (approximately 676%) better at full screen anti-aliasing than the Radeon R7 M260X, and also should be capable of handling higher resolutions more effectively. (explain)

Radeon R9 290		51200 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 44600 (676%)

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 maximum amount of data (counted in megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
