GeForce 8800 GTS (G92) vs Radeon R9 270X

Intro

Compare those specs to the Radeon R9 270X, which makes use of a 28 nm design. AMD has set the core speed at 1000 MHz. The GDDR5 RAM works at a frequency of 1400 MHz on this specific model. It features 1280 SPUs along with 80 Texture Address Units and 32 Rasterization Operator Units.

GeForce 8800 GTS (G92)		135 Watts
Radeon R9 270X		180 Watts
	Difference: 45 Watts (33%)

Memory Bandwidth

Theoretically speaking, the Radeon R9 270X should be quite a bit faster than the GeForce 8800 GTS (G92) overall. (explain)

Radeon R9 270X		179200 MB/sec
GeForce 8800 GTS (G92)		62080 MB/sec
	Difference: 117120 (189%)

Texel Rate

The Radeon R9 270X is a lot (about 92%) more effective at AF than the GeForce 8800 GTS (G92). (explain)

Radeon R9 270X		80000 Mtexels/sec
GeForce 8800 GTS (G92)		41600 Mtexels/sec
	Difference: 38400 (92%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R9 270X is a better choice, by far. (explain)

Radeon R9 270X		32000 Mpixels/sec
GeForce 8800 GTS (G92)		10400 Mpixels/sec
	Difference: 21600 (208%)

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 max amount of information (in units of MB per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the 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 texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one 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. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. 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, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
