Radeon R7 M260X vs Radeon R9 295X2

Intro

Compare those specs to the Radeon R9 295X2, which makes use of a 28 nm design. AMD has clocked the core speed at 1018 MHz. The GDDR5 RAM is set to run at a frequency of 1250 MHz on this specific card. It features 2816 SPUs as well as 176 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 295X2 should in theory be much superior to the Radeon R7 M260X overall. (explain)

Radeon R9 295X2		640000 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 576000 (900%)

Texel Rate

The Radeon R9 295X2 is much (approximately 1710%) faster with regards to AF than the Radeon R7 M260X. (explain)

Radeon R9 295X2		358336 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 338536 (1710%)

Pixel Rate

The Radeon R9 295X2 should be much (about 1874%) more effective at full screen anti-aliasing than the Radeon R7 M260X, and will be capable of handling higher resolutions without losing too much performance. (explain)

Radeon R9 295X2		130304 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 123704 (1874%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
