Radeon HD 5830 vs Radeon RX 460


Intro

The Radeon HD 5830 makes use of a 40 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 memory runs at a speed of 1000 MHz on this model. It features 1120(224x5) SPUs as well as 56 Texture Address Units and 16 ROPs.

Compare those specifications to the Radeon RX 460, which has core clock speeds of 1090 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 RAM. It features 896 SPUs along with 56 TAUs and 16 ROPs.

Radeon RX 460 75 Watts
Radeon HD 5830 175 Watts
Difference: 100 Watts (133%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 5830 should be 14% faster than the Radeon RX 460 in general, because of its higher bandwidth. (explain)

Radeon HD 5830 128000 MB/sec
Radeon RX 460 112000 MB/sec
Difference: 16000 (14%)

Texel Rate

The Radeon RX 460 is a lot (about 36%) better at texture filtering than the Radeon HD 5830. (explain)

Radeon RX 460 61040 Mtexels/sec
Radeon HD 5830 44800 Mtexels/sec
Difference: 16240 (36%)

Pixel Rate

The Radeon RX 460 will be a lot (more or less 36%) more effective at FSAA than the Radeon HD 5830, and also capable of handling higher resolutions without slowing down too much. (explain)

Radeon RX 460 17440 Mpixels/sec
Radeon HD 5830 12800 Mpixels/sec
Difference: 4640 (36%)

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 largest amount of data (in units of MB per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses 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, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of texture units 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 applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
