GeForce 8800 GT 256MB vs Radeon RX 5500

Intro

Compare that to the Radeon RX 5500, which makes use of a 7 nm design. AMD has clocked the core frequency at 1670 MHz. The GDDR6 memory works at a speed of 1750 MHz on this particular model. It features 1408 SPUs along with 88 TAUs and 32 Rasterization Operator Units.

GeForce 8800 GT 256MB		44800 MB/sec
	Difference: 184576 (412%)

Texel Rate

The Radeon RX 5500 is quite a bit (approximately 337%) better at AF than the GeForce 8800 GT 256MB. (explain)

Radeon RX 5500		146960 Mtexels/sec
GeForce 8800 GT 256MB		33600 Mtexels/sec
	Difference: 113360 (337%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 5500 is the winner, and very much so. (explain)

Radeon RX 5500		53440 Mpixels/sec
GeForce 8800 GT 256MB		9600 Mpixels/sec
	Difference: 43840 (457%)

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 maximum amount of information (in units of megabytes per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total amount of texture units by the core clock 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 most pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka 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, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
