GeForce GT 450 (OEM) vs Radeon R7 260X

Intro

The GeForce GT 450 (OEM) makes use of a 40 nm design. nVidia has clocked the core speed at 790 MHz. The GDDR5 RAM is set to run at a speed of 1000 MHz on this particular card. It features 144 SPUs along with 24 Texture Address Units and 24 ROPs.

Compare those specs to the Radeon R7 260X, which uses a 28 nm design. AMD has clocked the core speed at 1100 MHz. The GDDR5 memory works at a frequency of 1625 MHz on this particular model. It features 896 SPUs along with 56 TAUs and 16 ROPs.

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

In theory, the Radeon R7 260X is 8% quicker than the GeForce GT 450 (OEM) in general, because of its greater bandwidth. (explain)

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

Texel Rate

The Radeon R7 260X should be quite a bit (approximately 225%) faster with regards to 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 running with lots of anti-aliasing is important to you, then the GeForce GT 450 (OEM) is the winner, 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.

Memory Bandwidth: Bandwidth is the largest amount of data (in units of MB per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. 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 is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the video 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 maximum amount of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
