GeForce 8800 GT 256MB vs Radeon RX 590

Intro

Compare that to the Radeon RX 590, which uses a 12 nm design. AMD has clocked the core speed at 1469 MHz. The GDDR5 memory works at a speed of 2000 MHz on this particular card. It features 2304 SPUs along with 144 TAUs and 32 Rasterization Operator Units.

GeForce 8800 GT 256MB		105 Watts
Radeon RX 590		175 Watts
	Difference: 70 Watts (67%)

Memory Bandwidth

The Radeon RX 590 should in theory perform a lot faster than the GeForce 8800 GT 256MB in general. (explain)

Radeon RX 590		262144 MB/sec
GeForce 8800 GT 256MB		44800 MB/sec
	Difference: 217344 (485%)

Texel Rate

The Radeon RX 590 should be quite a bit (more or less 530%) better at texture filtering than the GeForce 8800 GT 256MB. (explain)

Radeon RX 590		211536 Mtexels/sec
GeForce 8800 GT 256MB		33600 Mtexels/sec
	Difference: 177936 (530%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 590 is superior to the GeForce 8800 GT 256MB, by a large margin. (explain)

Radeon RX 590		47008 Mpixels/sec
GeForce 8800 GT 256MB		9600 Mpixels/sec
	Difference: 37408 (390%)

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 data (counted in megabytes per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better 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 can be processed in one second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on 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 potential to reach the max fill rate.
