GeForce 810M vs Radeon R9 390X 8G

Intro

The GeForce 810M features core clock speeds of 738 MHz on the GPU, and 900 MHz on the 1024 MB of DDR3 memory. It features 48 SPUs as well as 8 TAUs and 4 Rasterization Operator Units.

Compare all that to the Radeon R9 390X 8G, which makes use of a 28 nm design. AMD has set the core frequency at 1050 MHz. The GDDR5 RAM is set to run at a frequency of 1500 MHz on this model. It features 2816 SPUs as well as 176 Texture Address Units and 64 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR 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 amount of texture units by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the card's 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.
