GeForce 8600 GT 1GB GDDR3 vs Radeon RX 560

Intro

Compare all of that to the Radeon RX 560, which makes use of a 14 nm design. AMD has clocked the core frequency at 1175 MHz. The GDDR5 memory runs at a speed of 1750 MHz on this specific card. It features 1024 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.

	Difference: 92288 (412%)

Texel Rate

The Radeon RX 560 will be a lot (about 770%) more effective at anisotropic filtering than the GeForce 8600 GT 1GB GDDR3. (explain)

Radeon RX 560		75200 Mtexels/sec
GeForce 8600 GT 1GB GDDR3		8640 Mtexels/sec
	Difference: 66560 (770%)

Pixel Rate

The Radeon RX 560 is a lot (about 335%) more effective at anti-aliasing than the GeForce 8600 GT 1GB GDDR3, and also will be able to handle higher screen resolutions better. (explain)

Radeon RX 560		18800 Mpixels/sec
GeForce 8600 GT 1GB GDDR3		4320 Mpixels/sec
	Difference: 14480 (335%)

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 largest amount of data (measured in megabytes per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
