GeForce GT 450 (OEM) vs Radeon R9 290X

Intro

Compare those specs to the Radeon R9 290X, which makes use of a 28 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 memory runs at a speed of 1250 MHz on this model. It features 2816 SPUs as well as 176 Texture Address Units and 64 ROPs.

GeForce GT 450 (OEM)		106 Watts
Radeon R9 290X		300 Watts
	Difference: 194 Watts (183%)

Memory Bandwidth

In theory, the Radeon R9 290X should be quite a bit faster than the GeForce GT 450 (OEM) overall. (explain)

Radeon R9 290X		320000 MB/sec
GeForce GT 450 (OEM)		96000 MB/sec
	Difference: 224000 (233%)

Texel Rate

The Radeon R9 290X is much (about 643%) more effective at anisotropic filtering than the GeForce GT 450 (OEM). (explain)

Radeon R9 290X		140800 Mtexels/sec
GeForce GT 450 (OEM)		18960 Mtexels/sec
	Difference: 121840 (643%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 290X is superior to the GeForce GT 450 (OEM), and very much so. (explain)

Radeon R9 290X		51200 Mpixels/sec
GeForce GT 450 (OEM)		18960 Mpixels/sec
	Difference: 32240 (170%)

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 maximum amount of data (measured in megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the clock 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 lots of 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.
