Radeon R7 250X 2GB vs Radeon R7 M265

Intro

Compare those specs to the Radeon R7 M265, which makes use of a 28 nm design. AMD has set the core speed at 725 MHz. The DDR3 RAM is set to run at a speed of 1000 MHz on this specific card. It features 384 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R7 250X 2GB should theoretically be a lot superior to the Radeon R7 M265 in general. (explain)

Radeon R7 250X 2GB		72000 MB/sec
Radeon R7 M265		32000 MB/sec
	Difference: 40000 (125%)

Texel Rate

The Radeon R7 250X 2GB should be much (more or less 130%) faster with regards to AF than the Radeon R7 M265. (explain)

Radeon R7 250X 2GB		40000 Mtexels/sec
Radeon R7 M265		17400 Mtexels/sec
	Difference: 22600 (130%)

Pixel Rate

The Radeon R7 250X 2GB will be quite a bit (more or less 176%) more effective at AA than the Radeon R7 M265, and also will be capable of handling higher resolutions more effectively. (explain)

Radeon R7 250X 2GB		16000 Mpixels/sec
Radeon R7 M265		5800 Mpixels/sec
	Difference: 10200 (176%)

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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the card's 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 quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
