GeForce GT 450 (OEM) vs Radeon R7 M265

Intro

Compare those specifications to the Radeon R7 M265, which features a GPU core clock speed of 725 MHz, and 2048 MB of DDR3 RAM set to run at 1000 MHz through a 128-bit bus. It also features 384 Stream Processors, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce GT 450 (OEM) should be quite a bit faster than the Radeon R7 M265 in general. (explain)

GeForce GT 450 (OEM)		96000 MB/sec
Radeon R7 M265		32000 MB/sec
	Difference: 64000 (200%)

Texel Rate

The GeForce GT 450 (OEM) should be a small bit (more or less 9%) better at texture filtering than the Radeon R7 M265. (explain)

GeForce GT 450 (OEM)		18960 Mtexels/sec
Radeon R7 M265		17400 Mtexels/sec
	Difference: 1560 (9%)

Pixel Rate

The GeForce GT 450 (OEM) is quite a bit (approximately 227%) more effective at FSAA than the Radeon R7 M265, and will be able to handle higher resolutions better. (explain)

GeForce GT 450 (OEM)		18960 Mpixels/sec
Radeon R7 M265		5800 Mpixels/sec
	Difference: 13160 (227%)

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 (measured in megabytes per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 texture map elements (texels) that can be applied per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
