Radeon HD 7870 XT vs Radeon R7 M360

Intro

Compare those specifications to the Radeon R7 M360, which comes with a clock frequency of 1125 MHz and a DDR3 memory speed of 1000 MHz. It also uses a 64-bit memory bus, and makes use of a 28 nm design. It features 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon HD 7870 XT should in theory be a lot superior to the Radeon R7 M360 in general. (explain)

Radeon HD 7870 XT		192000 MB/sec
Radeon R7 M360		16000 MB/sec
	Difference: 176000 (1100%)

Texel Rate

The Radeon HD 7870 XT should be quite a bit (approximately 229%) more effective at texture filtering than the Radeon R7 M360. (explain)

Radeon HD 7870 XT		88800 Mtexels/sec
Radeon R7 M360		27000 Mtexels/sec
	Difference: 61800 (229%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon HD 7870 XT is a better choice, by far. (explain)

Radeon HD 7870 XT		29600 Mpixels/sec
Radeon R7 M360		9000 Mpixels/sec
	Difference: 20600 (229%)

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 MB per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units by the core 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 per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can 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 Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
