Radeon R7 M260 vs Radeon R9 M295X

Intro

Compare all of that to the Radeon R9 M295X, which features a core clock speed of 750 MHz and a GDDR5 memory frequency of 1375 MHz. It also makes use of a 256-bit bus, and uses a 28 nm design. It features 2048 SPUs, 128 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M295X should in theory be quite a bit faster than the Radeon R7 M260 overall. (explain)

Radeon R9 M295X		176000 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 160000 (1000%)

Texel Rate

The Radeon R9 M295X will be much (more or less 459%) better at anisotropic filtering than the Radeon R7 M260. (explain)

Radeon R9 M295X		96000 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 78840 (459%)

Pixel Rate

The Radeon R9 M295X should be quite a bit (about 320%) better at AA than the Radeon R7 M260, and will be able to handle higher resolutions without losing too much performance. (explain)

Radeon R9 M295X		24000 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 18280 (320%)

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 information (in units of megabytes per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics 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 maximum number of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines 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 output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
