Radeon HD 7790 vs Radeon R7 M360

Intro

Compare all of that to the Radeon R7 M360, which has GPU clock speed of 1125 MHz, and 2048 MB of DDR3 RAM set to run at 1000 MHz through a 64-bit bus. It also is made up of 384 Stream Processors, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon HD 7790 should theoretically perform much faster than the Radeon R7 M360 in general. (explain)

Radeon HD 7790		96000 MB/sec
Radeon R7 M360		16000 MB/sec
	Difference: 80000 (500%)

Texel Rate

The Radeon HD 7790 will be much (about 107%) more effective at anisotropic filtering than the Radeon R7 M360. (explain)

Radeon HD 7790		56000 Mtexels/sec
Radeon R7 M360		27000 Mtexels/sec
	Difference: 29000 (107%)

Pixel Rate

The Radeon HD 7790 will be quite a bit (approximately 78%) more effective at AA than the Radeon R7 M360, and capable of handling higher resolutions without slowing down too much. (explain)

Radeon HD 7790		16000 Mpixels/sec
Radeon R7 M360		9000 Mpixels/sec
	Difference: 7000 (78%)

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 megabytes per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, 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 is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of 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 rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
