Radeon R7 250 vs Radeon RX 560

Intro

The Radeon R7 250 makes use of a 28 nm design. AMD has clocked the core speed at 1000 MHz. The GDDR5 memory is set to run at a frequency of 1150 MHz on this specific card. It features 384 SPUs as well as 24 TAUs and 8 ROPs.

Compare that to the Radeon RX 560, which has a clock speed of 1175 MHz and a GDDR5 memory frequency of 7000 MHz. It also features a 128-bit memory bus, and uses a 14 nm design. It is comprised of 1024 SPUs, 64 TAUs, and 16 Raster Operation Units.

Radeon RX 560 75200 Mtexels/sec
Radeon R7 250 24000 Mtexels/sec
Difference: 51200 (213%)

Pixel Rate

The Radeon RX 560 will be quite a bit (about 135%) better at AA than the Radeon R7 250, and capable of handling higher resolutions better. (explain)

Radeon RX 560 18800 Mpixels/sec
Radeon R7 250 8000 Mpixels/sec
Difference: 10800 (135%)

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 max amount of data (measured in megabytes per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 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 AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
