GeForce GTX 460 1GB vs Radeon R9 Nano

Intro

Compare those specs to the Radeon R9 Nano, which comes with a GPU core clock speed of 1000 MHz, and 4096 MB of HBM RAM set to run at 500 MHz through a 4096-bit bus. It also features 4096 SPUs, 256 TAUs, and 64 Raster Operation Units.

	Difference: 15 Watts (9%)

Memory Bandwidth

The Radeon R9 Nano should in theory perform quite a bit faster than the GeForce GTX 460 1GB in general. (explain)

Radeon R9 Nano		512000 MB/sec
GeForce GTX 460 1GB		115200 MB/sec
	Difference: 396800 (344%)

Texel Rate

The Radeon R9 Nano is a lot (more or less 577%) faster with regards to AF than the GeForce GTX 460 1GB. (explain)

Radeon R9 Nano		256000 Mtexels/sec
GeForce GTX 460 1GB		37800 Mtexels/sec
	Difference: 218200 (577%)

Pixel Rate

The Radeon R9 Nano should be quite a bit (approximately 196%) faster with regards to AA than the GeForce GTX 460 1GB, and should be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon R9 Nano		64000 Mpixels/sec
GeForce GTX 460 1GB		21600 Mpixels/sec
	Difference: 42400 (196%)

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 maximum amount of information (in units of MB per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
