GeForce GT 440 3GB		43200 MB/sec
	Difference: 186176 (431%)

Texel Rate

The Radeon RX 570 should be a lot (approximately 949%) more effective at texture filtering than the GeForce GT 440 3GB. (explain)

Radeon RX 570		149504 Mtexels/sec
GeForce GT 440 3GB		14256 Mtexels/sec
	Difference: 135248 (949%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 570 is superior to the GeForce GT 440 3GB, by far. (explain)

Radeon RX 570		37376 Mpixels/sec
GeForce GT 440 3GB		14256 Mpixels/sec
	Difference: 23120 (162%)

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 (counted in MB per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses 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, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total texture units 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 per second.

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