GeForce GT 430 vs Radeon R9 Nano

Intro

Compare that to the Radeon R9 Nano, which features a clock frequency of 1000 MHz and a HBM memory frequency of 500 MHz. It also uses a 4096-bit bus, and makes use of a 28 nm design. It is comprised of 4096 SPUs, 256 Texture Address Units, and 64 ROPs.

Texel Rate

The Radeon R9 Nano is a lot (about 2186%) more effective at AF than the GeForce GT 430. (explain)

Radeon R9 Nano		256000 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 244800 (2186%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R9 Nano is the winner, by far. (explain)

Radeon R9 Nano		64000 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 61200 (2186%)

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 (counted in megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed 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 card will be at 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 can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core 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 output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
