GeForce GT 450 (OEM) vs Radeon R7 M260X

Intro

Compare that to the Radeon R7 M260X, which makes use of a 28 nm design. AMD has set the core speed at 825 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this particular model. It features 384 SPUs along with 24 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GT 450 (OEM) should in theory be a lot superior to the Radeon R7 M260X in general. (explain)

GeForce GT 450 (OEM)		96000 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 32000 (50%)

Texel Rate

The Radeon R7 M260X is just a bit (about 4%) faster with regards to AF than the GeForce GT 450 (OEM). (explain)

Radeon R7 M260X		19800 Mtexels/sec
GeForce GT 450 (OEM)		18960 Mtexels/sec
	Difference: 840 (4%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GT 450 (OEM) is superior to the Radeon R7 M260X, by far. (explain)

GeForce GT 450 (OEM)		18960 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 12360 (187%)

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 max amount of data (counted in megabytes per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of texture units of the card 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in one 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 - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
