Radeon HD 5870 vs Radeon R7 M265

Intro

The Radeon HD 5870 comes with a GPU core speed of 850 MHz, and the 1024 MB of GDDR5 RAM is set to run at 1200 MHz through a 256-bit bus. It also is comprised of 1600(320x5) Stream Processors, 80 TAUs, and 32 Raster Operation Units.

Compare those specs to the Radeon R7 M265, which comes with a core clock frequency of 725 MHz and a DDR3 memory frequency of 1000 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It is made up of 384 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 5870 should perform quite a bit faster than the Radeon R7 M265 overall. (explain)

Radeon HD 5870 153600 MB/sec
Radeon R7 M265 32000 MB/sec
Difference: 121600 (380%)

Texel Rate

The Radeon HD 5870 is a lot (more or less 291%) more effective at anisotropic filtering than the Radeon R7 M265. (explain)

Radeon HD 5870 68000 Mtexels/sec
Radeon R7 M265 17400 Mtexels/sec
Difference: 50600 (291%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon HD 5870 is the winner, by far. (explain)

Radeon HD 5870 27200 Mpixels/sec
Radeon R7 M265 5800 Mpixels/sec
Difference: 21400 (369%)

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 maximum amount of data (in units of MB per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at 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 that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
