GeForce 9800 GT 1GB vs Radeon R9 270X

Intro

Compare that to the Radeon R9 270X, which features GPU core speed of 1000 MHz, and 2048 MB of GDDR5 RAM set to run at 1400 MHz through a 256-bit bus. It also is comprised of 1280 SPUs, 80 TAUs, and 32 Raster Operation Units.

Radeon R9 270X		180 Watts
	Difference: 75 Watts (71%)

Memory Bandwidth

Performance-wise, the Radeon R9 270X should in theory be much better than the GeForce 9800 GT 1GB in general. (explain)

Radeon R9 270X		179200 MB/sec
GeForce 9800 GT 1GB		57600 MB/sec
	Difference: 121600 (211%)

Texel Rate

The Radeon R9 270X should be a lot (approximately 138%) more effective at anisotropic filtering than the GeForce 9800 GT 1GB. (explain)

Radeon R9 270X		80000 Mtexels/sec
GeForce 9800 GT 1GB		33600 Mtexels/sec
	Difference: 46400 (138%)

Pixel Rate

The Radeon R9 270X will be quite a bit (more or less 233%) better at full screen anti-aliasing than the GeForce 9800 GT 1GB, and able to handle higher screen resolutions while still performing well. (explain)

Radeon R9 270X		32000 Mpixels/sec
GeForce 9800 GT 1GB		9600 Mpixels/sec
	Difference: 22400 (233%)

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 maximum amount of data (counted in megabytes per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 are applied per second. This is worked out by multiplying the total number 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 applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). 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 reach the max fill rate.
