Radeon HD 3470 256MB vs Radeon R7 M265

Intro

The Radeon HD 3470 256MB uses a 55 nm design. AMD has clocked the core frequency at 800 MHz. The DDR2 RAM runs at a speed of 950 MHz on this specific card. It features 40(8x5) SPUs as well as 4 TAUs and 4 Rasterization Operator Units.

Compare that to the Radeon R7 M265, which has GPU clock speed of 725 MHz, and 2048 MB of DDR3 RAM set to run at 1000 MHz through a 128-bit bus. It also features 384 SPUs, 24 Texture Address Units, and 8 ROPs.

Radeon R7 M265 17400 Mtexels/sec
Radeon HD 3470 256MB 3200 Mtexels/sec
Difference: 14200 (444%)

Pixel Rate

The Radeon R7 M265 will be quite a bit (about 81%) better at anti-aliasing than the Radeon HD 3470 256MB, and should be capable of handling higher resolutions more effectively. (explain)

Radeon R7 M265 5800 Mpixels/sec
Radeon HD 3470 256MB 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.

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
