GeForce GTX 480 vs Radeon RX 460 2GB

Intro

Compare those specifications to the Radeon RX 460 2GB, which uses a 14 nm design. AMD has set the core frequency at 1090 MHz. The GDDR5 RAM works at a frequency of 1750 MHz on this particular model. It features 896 SPUs as well as 56 Texture Address Units and 16 ROPs.

Radeon RX 460 2GB		112000 MB/sec
	Difference: 65408 (58%)

Texel Rate

The Radeon RX 460 2GB should be much (about 45%) faster with regards to texture filtering than the GeForce GTX 480. (explain)

Radeon RX 460 2GB		61040 Mtexels/sec
GeForce GTX 480		42000 Mtexels/sec
	Difference: 19040 (45%)

Pixel Rate

The GeForce GTX 480 should be quite a bit (more or less 93%) more effective at AA than the Radeon RX 460 2GB, and also able to handle higher resolutions without slowing down too much. (explain)

GeForce GTX 480		33600 Mpixels/sec
Radeon RX 460 2GB		17440 Mpixels/sec
	Difference: 16160 (93%)

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 largest amount of data (counted in MB per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. 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 reach the max fill rate.
