Radeon HD 3470 512MB vs Radeon R7 M265

Intro

Compare that to the Radeon R7 M265, which features a core clock frequency of 725 MHz and a DDR3 memory speed 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.

Radeon HD 3470 512MB		30400 MB/sec
	Difference: 1600 (5%)

Texel Rate

The Radeon R7 M265 is quite a bit (more or less 444%) better at AF than the Radeon HD 3470 512MB. (explain)

Radeon R7 M265		17400 Mtexels/sec
Radeon HD 3470 512MB		3200 Mtexels/sec
	Difference: 14200 (444%)

Pixel Rate

The Radeon R7 M265 will be a lot (about 81%) more effective at AA than the Radeon HD 3470 512MB, and capable of handling higher screen resolutions more effectively. (explain)

Radeon R7 M265		5800 Mpixels/sec
Radeon HD 3470 512MB		3200 Mpixels/sec
	Difference: 2600 (81%)

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: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the 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 texture map elements (texels) that are processed per second. This number is calculated by multiplying the total texture units by the core 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 maximum amount of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
