GeForce GT 450 (OEM) vs Radeon R7 M260

Intro

Compare those specs to the Radeon R7 M260, which has core clock speeds of 715 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 RAM. It features 384 SPUs along with 24 Texture Address Units and 8 ROPs.

Radeon R7 M260		17160 Mtexels/sec
	Difference: 1800 (10%)

Pixel Rate

The GeForce GT 450 (OEM) should be quite a bit (about 231%) more effective at full screen anti-aliasing than the Radeon R7 M260, and capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GT 450 (OEM)		18960 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 13240 (231%)

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 max amount of information (in units of MB per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range 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 worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output 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.
