Texel Rate

The Radeon R9 M395X will be quite a bit (more or less 549%) better at texture filtering than the GeForce GT 440 1.5GB. (explain)

Radeon R9 M395X		92544 Mtexels/sec
GeForce GT 440 1.5GB		14256 Mtexels/sec
	Difference: 78288 (549%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R9 M395X is superior to the GeForce GT 440 1.5GB, and very much so. (explain)

Radeon R9 M395X		23136 Mpixels/sec
GeForce GT 440 1.5GB		14256 Mpixels/sec
	Difference: 8880 (62%)

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 information (counted in MB per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the 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 number of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka 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 bandwidth is, the lower the potential to reach the maximum fill rate.
