GeForce GT 440 3GB vs Radeon R9 M375X

Intro

The GeForce GT 440 3GB features a clock speed of 594 MHz and a GDDR3 memory frequency of 900 MHz. It also uses a 192-bit memory bus, and makes use of a 40 nm design. It is comprised of 144 SPUs, 24 TAUs, and 24 Raster Operation Units.

Compare those specifications to the Radeon R9 M375X, which uses a 28 nm design. AMD has set the core frequency at 1015 MHz. The GDDR5 RAM is set to run at a frequency of 1125 MHz on this card. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Radeon R9 M375X 72000 MB/sec
GeForce GT 440 3GB 43200 MB/sec
Difference: 28800 (67%)

Texel Rate

The Radeon R9 M375X is a lot (approximately 185%) better at texture filtering than the GeForce GT 440 3GB. (explain)

Radeon R9 M375X 40600 Mtexels/sec
GeForce GT 440 3GB 14256 Mtexels/sec
Difference: 26344 (185%)

Pixel Rate

The Radeon R9 M375X is a bit (approximately 14%) better at full screen anti-aliasing than the GeForce GT 440 3GB, and also should be capable of handling 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: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of texture units 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 processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core speed of the card. 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 many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
