GeForce 8600 GT 1GB GDDR3 vs Radeon RX 5700 XT

Intro

The GeForce 8600 GT 1GB GDDR3 comes with a GPU core clock speed of 540 MHz, and the 1024 MB of GDDR3 RAM is set to run at 700 MHz through a 128-bit bus. It also is made up of 32 Stream Processors, 16 Texture Address Units, and 8 Raster Operation Units.

Compare those specs to the Radeon RX 5700 XT, which uses a 7 nm design. AMD has clocked the core speed at 1605 MHz. The GDDR6 memory works at a frequency of 1750 MHz on this specific card. It features 2560 SPUs along with 160 Texture Address Units and 64 Rasterization Operator Units.

The Radeon RX 5700 XT should be much (approximately 2872%) more effective at anisotropic filtering than the GeForce 8600 GT 1GB GDDR3. (explain)

Radeon RX 5700 XT 256800 Mtexels/sec
GeForce 8600 GT 1GB GDDR3 8640 Mtexels/sec
Difference: 248160 (2872%)

Pixel Rate

The Radeon RX 5700 XT should be much (about 2278%) more effective at AA than the GeForce 8600 GT 1GB GDDR3, and also should be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 5700 XT 102720 Mpixels/sec
GeForce 8600 GT 1GB GDDR3 4320 Mpixels/sec
Difference: 98400 (2278%)

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.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
