GeForce GT 430 1GB vs Radeon RX 570

Intro

Compare those specs to the Radeon RX 570, which comes with a GPU core clock speed of 1168 MHz, and 4096 MB of GDDR5 RAM set to run at 1750 MHz through a 256-bit bus. It also features 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 will be 696% faster than the GeForce GT 430 1GB in general, due to its higher bandwidth. (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%) more effective 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 resolutions without slowing down too much. (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 information (in units of MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video 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 graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. 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 quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
