GeForce GT 450 (OEM) vs Radeon R9 M365X

Intro

Compare those specifications to the Radeon R9 M365X, which has GPU clock speed of 925 MHz, and 4096 MB of GDDR5 memory set to run at 1125 MHz through a 128-bit bus. It also features 640 Stream Processors, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GT 450 (OEM) will be 33% quicker than the Radeon R9 M365X overall, because of its higher bandwidth. (explain)

GeForce GT 450 (OEM)		96000 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 24000 (33%)

Texel Rate

The Radeon R9 M365X is quite a bit (approximately 95%) more effective at anisotropic filtering than the GeForce GT 450 (OEM). (explain)

Radeon R9 M365X		37000 Mtexels/sec
GeForce GT 450 (OEM)		18960 Mtexels/sec
	Difference: 18040 (95%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GT 450 (OEM) is a better choice, by far. (explain)

GeForce GT 450 (OEM)		18960 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 4160 (28%)

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 maximum amount of information (in units of megabytes per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
