GeForce GT 450 (OEM) vs Radeon RX 560

Intro

The GeForce GT 450 (OEM) makes use of a 40 nm design. nVidia has set the core frequency at 790 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this card. It features 144 SPUs as well as 24 Texture Address Units and 24 ROPs.

Compare all that to the Radeon RX 560, which features GPU clock speed of 1175 MHz, and 4096 MB of GDDR5 memory running at 7000 MHz through a 128-bit bus. It also features 1024 Stream Processors, 64 Texture Address Units, and 16 ROPs.

GeForce GT 450 (OEM) 96000 MB/sec
Difference: 18688 (19%)

Texel Rate

The Radeon RX 560 is quite a bit (about 297%) better at anisotropic filtering than the GeForce GT 450 (OEM). (explain)

Radeon RX 560 75200 Mtexels/sec
GeForce GT 450 (OEM) 18960 Mtexels/sec
Difference: 56240 (297%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GT 450 (OEM) is the winner, but not by far. (explain)

GeForce GT 450 (OEM) 18960 Mpixels/sec
Radeon RX 560 18800 Mpixels/sec
Difference: 160 (1%)

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.

Memory Bandwidth: Memory bandwidth is the max amount of information (measured in MB per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 number of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video 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 most pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
