GeForce 920M vs Radeon R9 Nano

Intro

The GeForce 920M makes use of a 28 nm design. nVidia has set the core frequency at 954 MHz. The DDR3 memory is set to run at a frequency of 900 MHz on this particular model. It features 384 SPUs as well as 32 Texture Address Units and 8 ROPs.

Compare all of that to the Radeon R9 Nano, which comes with a core clock speed of 1000 MHz and a HBM memory speed of 500 MHz. It also features a 4096-bit bus, and uses a 28 nm design. It is comprised of 4096 SPUs, 256 TAUs, and 64 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 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 anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out 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 fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
