GeForce GT 450 (OEM) vs Radeon RX 570

Intro

Compare those specs to the Radeon RX 570, which features core speeds of 1168 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 memory. It features 2048 SPUs as well as 128 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 450 (OEM)		106 Watts
Radeon RX 570		150 Watts
	Difference: 44 Watts (42%)

Memory Bandwidth

Theoretically, the Radeon RX 570 should perform much faster than the GeForce GT 450 (OEM) in general. (explain)

Radeon RX 570		229376 MB/sec
GeForce GT 450 (OEM)		96000 MB/sec
	Difference: 133376 (139%)

Texel Rate

The Radeon RX 570 should be a lot (more or less 689%) more effective at anisotropic filtering than the GeForce GT 450 (OEM). (explain)

Radeon RX 570		149504 Mtexels/sec
GeForce GT 450 (OEM)		18960 Mtexels/sec
	Difference: 130544 (689%)

Pixel Rate

The Radeon RX 570 will be quite a bit (approximately 97%) more effective at anti-aliasing than the GeForce GT 450 (OEM), and also capable of handling higher screen resolutions more effectively. (explain)

Radeon RX 570		37376 Mpixels/sec
GeForce GT 450 (OEM)		18960 Mpixels/sec
	Difference: 18416 (97%)

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 (in units of megabytes per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
