Radeon HD 4790 vs Radeon RX 460 2GB

Intro

The Radeon HD 4790 features a GPU core speed of 600 MHz, and the 512 MB of GDDR5 RAM is set to run at 800 MHz through a 256-bit bus. It also features 640(128x5) Stream Processors, 32 TAUs, and 16 ROPs.

Compare that to the Radeon RX 460 2GB, which uses 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 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon RX 460 2GB should in theory be a small bit better than the Radeon HD 4790 overall. (explain)

Radeon RX 460 2GB 112000 MB/sec
Radeon HD 4790 102400 MB/sec
Difference: 9600 (9%)

Texel Rate

The Radeon RX 460 2GB will be quite a bit (approximately 218%) faster with regards to texture filtering than the Radeon HD 4790. (explain)

Radeon RX 460 2GB 61040 Mtexels/sec
Radeon HD 4790 19200 Mtexels/sec
Difference: 41840 (218%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 460 2GB is the winner, by far. (explain)

Radeon RX 460 2GB 17440 Mpixels/sec
Radeon HD 4790 9600 Mpixels/sec
Difference: 7840 (82%)

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.

Memory Bandwidth: Bandwidth is the max amount of information (counted in megabytes per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. 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 rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
