The Radeon R9 M395X should be a lot (about 126%) more effective at anisotropic filtering than the GeForce GTX 560 Ti 448. (explain)

Radeon R9 M395X		92544 Mtexels/sec
GeForce GTX 560 Ti 448		40992 Mtexels/sec
	Difference: 51552 (126%)

Pixel Rate

The GeForce GTX 560 Ti 448 is quite a bit (approximately 27%) more effective at full screen anti-aliasing than the Radeon R9 M395X, and should be able to handle higher screen resolutions while still performing well. (explain)

GeForce GTX 560 Ti 448		29280 Mpixels/sec
Radeon R9 M395X		23136 Mpixels/sec
	Difference: 6144 (27%)

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 (measured in megabytes per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
