GeForce GT 440 3GB vs Radeon R9 M265X

Intro

Compare those specs to the Radeon R9 M265X, which features a core clock frequency of 575 MHz and a GDDR5 memory frequency of 1125 MHz. It also uses a 128-bit memory bus, and uses a 28 nm design. It is made up of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R9 M265X should perform a lot faster than the GeForce GT 440 3GB overall. (explain)

Radeon R9 M265X		72000 MB/sec
GeForce GT 440 3GB		43200 MB/sec
	Difference: 28800 (67%)

Texel Rate

The Radeon R9 M265X should be much (approximately 61%) faster with regards to anisotropic filtering than the GeForce GT 440 3GB. (explain)

Radeon R9 M265X		23000 Mtexels/sec
GeForce GT 440 3GB		14256 Mtexels/sec
	Difference: 8744 (61%)

Pixel Rate

The GeForce GT 440 3GB is quite a bit (approximately 55%) more effective at FSAA than the Radeon R9 M265X, and also should be able to handle higher resolutions while still performing well. (explain)

GeForce GT 440 3GB		14256 Mpixels/sec
Radeon R9 M265X		9200 Mpixels/sec
	Difference: 5056 (55%)

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: Bandwidth is the largest amount of data (in units of MB per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 applied in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
