The Radeon R9 M380 will be a lot (more or less 52%) more effective at AF than the GeForce 9600 GSO 768MB. (explain)

Radeon R9 M380		40000 Mtexels/sec
GeForce 9600 GSO 768MB		26400 Mtexels/sec
	Difference: 13600 (52%)

Pixel Rate

The Radeon R9 M380 will be quite a bit (more or less 142%) more effective at AA than the GeForce 9600 GSO 768MB, and also will be able to handle higher resolutions without slowing down too much. (explain)

Radeon R9 M380		16000 Mpixels/sec
GeForce 9600 GSO 768MB		6600 Mpixels/sec
	Difference: 9400 (142%)

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 moved over the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
