Radeon HD 5570 vs Radeon R7 240

Intro

The Radeon HD 5570 comes with a GPU clock speed of 650 MHz, and the 512 MB of DDR3 memory is set to run at 900 MHz through a 128-bit bus. It also is made up of 400(80x5) Stream Processors, 20 TAUs, and 8 ROPs.

Compare that to the Radeon R7 240, which features a core clock speed of 730 MHz and a DDR3 memory speed of 900 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It is comprised of 320 SPUs, 20 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 240 30 Watts
Radeon HD 5570 43 Watts
Difference: 13 Watts (43%)

Memory Bandwidth

Both cards have the exact same memory bandwidth, so theoretically they should perform the same. (explain)

Texel Rate

The Radeon R7 240 will be a small bit (more or less 12%) faster with regards to texture filtering than the Radeon HD 5570. (explain)

Radeon R7 240 14600 Mtexels/sec
Radeon HD 5570 13000 Mtexels/sec
Difference: 1600 (12%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R7 240 is a better choice, though not by far. (explain)

Radeon R7 240 5840 Mpixels/sec
Radeon HD 5570 5200 Mpixels/sec
Difference: 640 (12%)

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 data (measured in MB per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units 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 rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
