GeForce GT 440 3GB vs Radeon R9 M375X

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 works at a frequency of 900 MHz on this card. It features 144 SPUs along with 24 Texture Address Units and 24 ROPs.

Compare those specs to the Radeon R9 M375X, which comes with GPU clock speed of 1015 MHz, and 4096 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also is comprised of 640 Stream Processors, 40 Texture Address Units, and 16 Raster Operation Units.

GeForce GT 440 3GB 14256 Mtexels/sec
Difference: 26344 (185%)

Pixel Rate

The Radeon R9 M375X will be a little bit (more or less 14%) faster with regards to AA than the GeForce GT 440 3GB, and also should be able to handle higher screen resolutions more effectively. (explain)

Radeon R9 M375X 16240 Mpixels/sec
GeForce GT 440 3GB 14256 Mpixels/sec
Difference: 1984 (14%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

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

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
