GeForce GTX 470 vs Radeon RX 460 2GB

Intro

Compare all of that to the Radeon RX 460 2GB, which makes use of a 14 nm design. AMD has clocked the core speed at 1090 MHz. The GDDR5 RAM is set to run at a speed of 1750 MHz on this particular card. It features 896 SPUs along with 56 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 460 2GB		75 Watts
GeForce GTX 470		215 Watts
	Difference: 140 Watts (187%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 470 will be 20% faster than the Radeon RX 460 2GB in general, because of its higher bandwidth. (explain)

GeForce GTX 470		133920 MB/sec
Radeon RX 460 2GB		112000 MB/sec
	Difference: 21920 (20%)

Texel Rate

The Radeon RX 460 2GB should be a lot (more or less 80%) more effective at texture filtering than the GeForce GTX 470. (explain)

Radeon RX 460 2GB		61040 Mtexels/sec
GeForce GTX 470		33992 Mtexels/sec
	Difference: 27048 (80%)

Pixel Rate

The GeForce GTX 470 should be a lot (about 39%) faster with regards to AA than the Radeon RX 460 2GB, and also able to handle higher resolutions without losing too much performance. (explain)

GeForce GTX 470		24280 Mpixels/sec
Radeon RX 460 2GB		17440 Mpixels/sec
	Difference: 6840 (39%)

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 max amount of data (measured in megabytes per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video 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 maximum amount of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
