Radeon HD 5570 vs Radeon R7 M265

Intro

The Radeon HD 5570 has a core clock frequency of 650 MHz and a DDR3 memory speed of 900 MHz. It also features a 128-bit bus, and makes use of a 40 nm design. It features 400(80x5) SPUs, 20 TAUs, and 8 ROPs.

Compare those specifications to the Radeon R7 M265, which has a clock frequency of 725 MHz and a DDR3 memory frequency of 1000 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It is made up of 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R7 M265 should in theory be just a bit better than the Radeon HD 5570 overall. (explain)

Radeon R7 M265 32000 MB/sec
Radeon HD 5570 28800 MB/sec
Difference: 3200 (11%)

Texel Rate

The Radeon R7 M265 should be quite a bit (approximately 34%) better at AF than the Radeon HD 5570. (explain)

Radeon R7 M265 17400 Mtexels/sec
Radeon HD 5570 13000 Mtexels/sec
Difference: 4400 (34%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R7 M265 is superior to the Radeon HD 5570, not by a very large margin though. (explain)

Radeon R7 M265 5800 Mpixels/sec
Radeon HD 5570 5200 Mpixels/sec
Difference: 600 (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 max amount of data (measured in megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines 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 also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
