GeForce 8800 GS vs Radeon R7 260X

Intro

Compare all that to the Radeon R7 260X, which uses a 28 nm design. AMD has clocked the core frequency at 1100 MHz. The GDDR5 RAM runs at a speed of 1625 MHz on this card. It features 896 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GS		105 Watts
Radeon R7 260X		115 Watts
	Difference: 10 Watts (10%)

Memory Bandwidth

The Radeon R7 260X should in theory be much faster than the GeForce 8800 GS overall. (explain)

Radeon R7 260X		104000 MB/sec
GeForce 8800 GS		38400 MB/sec
	Difference: 65600 (171%)

Texel Rate

The Radeon R7 260X is a lot (more or less 133%) faster with regards to anisotropic filtering than the GeForce 8800 GS. (explain)

Radeon R7 260X		61600 Mtexels/sec
GeForce 8800 GS		26400 Mtexels/sec
	Difference: 35200 (133%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R7 260X is the winner, and very much so. (explain)

Radeon R7 260X		17600 Mpixels/sec
GeForce 8800 GS		6600 Mpixels/sec
	Difference: 11000 (167%)

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 max amount of information (counted in megabytes per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
