GeForce GTX 950M vs Radeon HD 3470 512MB

Intro

The GeForce GTX 950M features clock speeds of 914 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 RAM. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Compare that to the Radeon HD 3470 512MB, which uses a 55 nm design. AMD has set the core frequency at 800 MHz. The GDDR3 RAM works at a frequency of 950 MHz on this particular model. It features 40(8x5) SPUs along with 4 Texture Address Units and 4 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
