Radeon HD 3470 256MB vs Radeon R7 M265

Intro

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

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 frequency of 1000 MHz on this model. It features 384 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once 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 AA, High Dynamic Range 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 worked out by multiplying the total amount of texture units 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 applied per second.

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