GeForce GT 440 3GB vs Radeon R9 M365X

Intro

Compare all of that to the Radeon R9 M365X, which uses a 28 nm design. AMD has clocked the core frequency at 925 MHz. The GDDR5 RAM runs at a speed of 1125 MHz on this specific card. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M365X should theoretically be a lot superior to the GeForce GT 440 3GB in general. (explain)

Radeon R9 M365X		72000 MB/sec
GeForce GT 440 3GB		43200 MB/sec
	Difference: 28800 (67%)

Texel Rate

The Radeon R9 M365X will be quite a bit (more or less 160%) more effective at AF than the GeForce GT 440 3GB. (explain)

Radeon R9 M365X		37000 Mtexels/sec
GeForce GT 440 3GB		14256 Mtexels/sec
	Difference: 22744 (160%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 M365X is a better choice, but not by far. (explain)

Radeon R9 M365X		14800 Mpixels/sec
GeForce GT 440 3GB		14256 Mpixels/sec
	Difference: 544 (4%)

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 largest amount of information (in units of MB per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's 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 number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its 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 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 fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
