GeForce GT 450 (OEM) vs Radeon R7 260X

Intro

Compare those specs to the Radeon R7 260X, which uses a 28 nm design. AMD has set the core speed at 1100 MHz. The GDDR5 memory is set to run at a speed of 1625 MHz on this particular model. It features 896 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 450 (OEM)		106 Watts
Radeon R7 260X		115 Watts
	Difference: 9 Watts (8%)

Memory Bandwidth

As far as performance goes, the Radeon R7 260X should in theory be just a bit superior to the GeForce GT 450 (OEM) overall. (explain)

Radeon R7 260X		104000 MB/sec
GeForce GT 450 (OEM)		96000 MB/sec
	Difference: 8000 (8%)

Texel Rate

The Radeon R7 260X will be a lot (more or less 225%) better at anisotropic filtering than the GeForce GT 450 (OEM). (explain)

Radeon R7 260X		61600 Mtexels/sec
GeForce GT 450 (OEM)		18960 Mtexels/sec
	Difference: 42640 (225%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GT 450 (OEM) is a better choice, but it probably won't make a huge difference. (explain)

GeForce GT 450 (OEM)		18960 Mpixels/sec
Radeon R7 260X		17600 Mpixels/sec
	Difference: 1360 (8%)

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 (measured in megabytes per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a 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. The figure is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
