GeForce GT 440 3GB vs Radeon RX 570

Intro

Compare all that to the Radeon RX 570, which makes use of a 14 nm design. AMD has set the core frequency at 1168 MHz. The GDDR5 memory runs at a speed of 1750 MHz on this card. It features 2048 SPUs along with 128 Texture Address Units and 32 Rasterization Operator Units.

	Difference: 135248 (949%)

Pixel Rate

The Radeon RX 570 should be quite a bit (approximately 162%) more effective at full screen anti-aliasing than the GeForce GT 440 3GB, and also will be able to handle higher screen resolutions more effectively. (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 (measured in MB per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel 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 reach the maximum fill rate.
