GeForce GT 430 1GB vs Radeon RX 570

Intro

Compare that to the Radeon RX 570, which comes with a clock frequency of 1168 MHz and a GDDR5 memory frequency of 1750 MHz. It also makes use of a 256-bit memory bus, and makes use of a 14 nm design. It is comprised of 2048 SPUs, 128 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 430 1GB		60 Watts
Radeon RX 570		150 Watts
	Difference: 90 Watts (150%)

Memory Bandwidth

In theory, the Radeon RX 570 should perform much faster than the GeForce GT 430 1GB overall. (explain)

Radeon RX 570		229376 MB/sec
GeForce GT 430 1GB		28800 MB/sec
	Difference: 200576 (696%)

Texel Rate

The Radeon RX 570 is a lot (about 1235%) better at AF than the GeForce GT 430 1GB. (explain)

Radeon RX 570		149504 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 138304 (1235%)

Pixel Rate

The Radeon RX 570 will be quite a bit (more or less 1235%) more effective at FSAA than the GeForce GT 430 1GB, and should be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon RX 570		37376 Mpixels/sec
GeForce GT 430 1GB		2800 Mpixels/sec
	Difference: 34576 (1235%)

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: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core 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 output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
