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

Intro

The GeForce GT 440 3GB makes use of a 40 nm design. nVidia has set the core frequency at 594 MHz. The GDDR3 memory is set to run at a frequency of 900 MHz on this card. It features 144 SPUs as well as 24 Texture Address Units and 24 ROPs.

Compare those specs to the Radeon R9 390X 8G, which comes with core clock speeds of 1050 MHz on the GPU, and 1500 MHz on the 8192 MB of GDDR5 memory. It features 2816 SPUs along with 176 Texture Address Units and 64 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If it uses 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, HDR and high resolutions.

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

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