GeForce 8800 GT 1GB vs Radeon RX 5500

Intro

Compare those specs to the Radeon RX 5500, which has GPU clock speed of 1670 MHz, and 4096 MB of GDDR6 RAM set to run at 1750 MHz through a 128-bit bus. It also features 1408 SPUs, 88 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GT 1GB		105 Watts
Radeon RX 5500		150 Watts
	Difference: 45 Watts (43%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5500 will be 298% faster than the GeForce 8800 GT 1GB overall, due to its higher bandwidth. (explain)

Radeon RX 5500		229376 MB/sec
GeForce 8800 GT 1GB		57600 MB/sec
	Difference: 171776 (298%)

Texel Rate

The Radeon RX 5500 will be much (approximately 337%) faster with regards to AF than the GeForce 8800 GT 1GB. (explain)

Radeon RX 5500		146960 Mtexels/sec
GeForce 8800 GT 1GB		33600 Mtexels/sec
	Difference: 113360 (337%)

Pixel Rate

The Radeon RX 5500 should be quite a bit (more or less 457%) faster with regards to full screen anti-aliasing than the GeForce 8800 GT 1GB, and will be able to handle higher screen resolutions more effectively. (explain)

Radeon RX 5500		53440 Mpixels/sec
GeForce 8800 GT 1GB		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 largest amount of information (in units of MB per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock 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 applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
