Radeon R7 M260X vs Radeon R9 M395X

Intro

Compare all of that to the Radeon R9 M395X, which makes use of a 28 nm design. AMD has set the core speed at 723 MHz. The GDDR5 RAM runs at a speed of 1250 MHz on this model. It features 2048 SPUs as well as 128 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M395X should be quite a bit faster than the Radeon R7 M260X overall. (explain)

Radeon R9 M395X		160000 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 96000 (150%)

Texel Rate

The Radeon R9 M395X will be a lot (more or less 367%) more effective at AF than the Radeon R7 M260X. (explain)

Radeon R9 M395X		92544 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 72744 (367%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R9 M395X is superior to the Radeon R7 M260X, and very much so. (explain)

Radeon R9 M395X		23136 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 16536 (251%)

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 megabytes per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 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 higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock 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 fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
