Radeon R5 M230		16000 MB/sec
	Difference: 56000 (350%)

Texel Rate

The Radeon HD 7770 is quite a bit (approximately 156%) more effective at anisotropic filtering than the Radeon R5 M230. (explain)

Radeon HD 7770		40000 Mtexels/sec
Radeon R5 M230		15600 Mtexels/sec
	Difference: 24400 (156%)

Pixel Rate

The Radeon HD 7770 should be quite a bit (about 413%) more effective at full screen anti-aliasing than the Radeon R5 M230, and will be able to handle higher resolutions more effectively. (explain)

Radeon HD 7770		16000 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 12880 (413%)

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 largest amount of data (in units of megabytes per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 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 AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of 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.
