Radeon HD 4870 2GB vs Radeon RX 460

Intro

The Radeon HD 4870 2GB uses a 55 nm design. AMD has clocked the core speed at 750 MHz. The GDDR5 memory runs at a speed of 900 MHz on this model. It features 800(160x5) SPUs as well as 40 TAUs and 16 ROPs.

Compare those specifications to the Radeon RX 460, which comes with a core clock speed of 1090 MHz and a GDDR5 memory speed of 1750 MHz. It also uses a 128-bit bus, and uses a 14 nm design. It is made up of 896 SPUs, 56 TAUs, and 16 Raster Operation Units.

Radeon RX 460 61040 Mtexels/sec
Radeon HD 4870 2GB 30000 Mtexels/sec
Difference: 31040 (103%)

Pixel Rate

The Radeon RX 460 will be a lot (more or less 45%) more effective at FSAA than the Radeon HD 4870 2GB, and able to handle higher resolutions without slowing down too much. (explain)

Radeon RX 460 17440 Mpixels/sec
Radeon HD 4870 2GB 12000 Mpixels/sec
Difference: 5440 (45%)

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: Memory bandwidth is the largest amount of information (counted in MB per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, 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 texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
