Radeon R7 M260 vs Radeon R9 M370X

Intro

Compare all of that to the Radeon R9 M370X, which features a clock frequency of 800 MHz and a GDDR5 memory speed of 1125 MHz. It also features a 128-bit memory bus, and makes use of a 28 nm design. It is made up of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M370X should in theory be much better than the Radeon R7 M260 in general. (explain)

Radeon R9 M370X		72000 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 56000 (350%)

Texel Rate

The Radeon R9 M370X is a lot (more or less 86%) faster with regards to texture filtering than the Radeon R7 M260. (explain)

Radeon R9 M370X		32000 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 14840 (86%)

Pixel Rate

The Radeon R9 M370X is quite a bit (about 124%) more effective at full screen anti-aliasing than the Radeon R7 M260, and also should be capable of handling higher screen resolutions more effectively. (explain)

Radeon R9 M370X		12800 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 7080 (124%)

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 (in units of MB per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

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