GeForce GT 440 3GB vs Radeon R7 240

Intro

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

Compare those specs to the Radeon R7 240, which comes with GPU clock speed of 730 MHz, and 2048 MB of DDR3 memory running at 900 MHz through a 128-bit bus. It also features 320 SPUs, 20 TAUs, and 8 ROPs.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in MB per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

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