GeForce GTX 460 2GB vs Radeon RX 470

Intro

Compare all of that to the Radeon RX 470, which uses a 14 nm design. AMD has set the core frequency at 926 MHz. The GDDR5 RAM works at a speed of 1650 MHz on this specific card. It features 2048 SPUs as well as 128 Texture Address Units and 32 ROPs.

Radeon RX 470		120 Watts
GeForce GTX 460 2GB		160 Watts
	Difference: 40 Watts (33%)

Memory Bandwidth

As far as performance goes, the Radeon RX 470 should in theory be much better than the GeForce GTX 460 2GB overall. (explain)

Radeon RX 470		211200 MB/sec
GeForce GTX 460 2GB		115200 MB/sec
	Difference: 96000 (83%)

Texel Rate

The Radeon RX 470 should be quite a bit (approximately 214%) better at anisotropic filtering than the GeForce GTX 460 2GB. (explain)

Radeon RX 470		118528 Mtexels/sec
GeForce GTX 460 2GB		37800 Mtexels/sec
	Difference: 80728 (214%)

Pixel Rate

The Radeon RX 470 should be a lot (about 37%) faster with regards to full screen anti-aliasing than the GeForce GTX 460 2GB, and also should be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 470		29632 Mpixels/sec
GeForce GTX 460 2GB		21600 Mpixels/sec
	Difference: 8032 (37%)

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 MB per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher 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 applied in one second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can 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 core 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 output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
