GeForce GT 440 1.5GB vs Radeon R9 M375

Intro

Compare all of that to the Radeon R9 M375, which has a clock speed of 1015 MHz and a DDR3 memory speed of 1100 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It features 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GT 440 1.5GB, in theory, should be a lot faster than the Radeon R9 M375 overall. (explain)

GeForce GT 440 1.5GB		43200 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 8000 (23%)

Texel Rate

The Radeon R9 M375 is a lot (more or less 185%) more effective at texture filtering than the GeForce GT 440 1.5GB. (explain)

Radeon R9 M375		40600 Mtexels/sec
GeForce GT 440 1.5GB		14256 Mtexels/sec
	Difference: 26344 (185%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R9 M375 is the winner, but not by far. (explain)

Radeon R9 M375		16240 Mpixels/sec
GeForce GT 440 1.5GB		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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be moved over 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 RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's 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 many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
