GeForce GT 430 1GB vs Radeon R9 Nano

Intro

Compare all that to the Radeon R9 Nano, which makes use of a 28 nm design. AMD has clocked the core speed at 1000 MHz. The HBM memory works at a frequency of 500 MHz on this particular card. It features 4096 SPUs along with 256 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 430 1GB		60 Watts
Radeon R9 Nano		175 Watts
	Difference: 115 Watts (192%)

Memory Bandwidth

Performance-wise, the Radeon R9 Nano should in theory be much superior to the GeForce GT 430 1GB in general. (explain)

Radeon R9 Nano		512000 MB/sec
GeForce GT 430 1GB		28800 MB/sec
	Difference: 483200 (1678%)

Texel Rate

The Radeon R9 Nano should be quite a bit (about 2186%) more effective at AF than the GeForce GT 430 1GB. (explain)

Radeon R9 Nano		256000 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 244800 (2186%)

Pixel Rate

The Radeon R9 Nano is a lot (more or less 2186%) faster with regards to AA than the GeForce GT 430 1GB, and also should be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon R9 Nano		64000 Mpixels/sec
GeForce GT 430 1GB		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: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the 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 are applied per second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
