GeForce GT 440 3GB vs Radeon R9 390X 8G

Intro

The GeForce GT 440 3GB has a clock speed of 594 MHz and a GDDR3 memory frequency of 900 MHz. It also makes use of a 192-bit memory bus, and makes use of a 40 nm design. It is made up of 144 SPUs, 24 Texture Address Units, and 24 ROPs.

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

Memory Bandwidth: Bandwidth is the max amount of data (counted in megabytes per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

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