Understand why memory and clock data differs between sources

[gkjohnson]

Despite seeming to refer to the exact same card in name the different database sources seem to list different hardware information such as memory limit, etc.

Examples:
GeForce RTX 2070, GeForce RTX 2070
8096, 8192

GeForce GTX 770, GeForce GTX 770
4096, 2048

Radeon HD 6470M, Radeon HD 6470M
1024, 512

In some cases there's been variants of the same GPU with different memory but the same model number. Clocks could also vary based on how the card was tuned. Sometimes even different chips have been sold under the same low-end model name, though this is rarer.

That makes sense -- I was hoping they'd be named differently in that case, though 😬

I originally intending to use some of that secondary data to help more precisely validate and merge GPU entries across data sources but it might not be all that useful if the names can't be differentiated.
