Radeon HD 7770 vs Radeon R7 M360

Intro

Compare those specs to the Radeon R7 M360, which makes use of a 28 nm design. AMD has clocked the core frequency at 1125 MHz. The DDR3 memory runs at a speed of 1000 MHz on this model. It features 384 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 7770 will be 350% quicker than the Radeon R7 M360 overall, due to its higher data rate. (explain)

Radeon HD 7770		72000 MB/sec
Radeon R7 M360		16000 MB/sec
	Difference: 56000 (350%)

Texel Rate

The Radeon HD 7770 will be a lot (about 48%) better at AF than the Radeon R7 M360. (explain)

Radeon HD 7770		40000 Mtexels/sec
Radeon R7 M360		27000 Mtexels/sec
	Difference: 13000 (48%)

Pixel Rate

The Radeon HD 7770 is quite a bit (approximately 78%) more effective at AA than the Radeon R7 M360, and also should be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon HD 7770		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 max amount of data (measured in MB per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's 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 amount of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

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