Favorite chart/website for CAT5, 5e, 6, etc differences? (beehaw.org)

I always forget the speed differences (and other specs) for ethernet cables. I can find what I need from various sources, but I haven’t been able to find a good chart with the info I want to print out at work. Most likely I’ll create my own, but I’m curious what’s already out there.

Looks like we’re up to CAT8 now, with limit of 30meters, whereas CAT7 and lower are all 100m at their base speeds. Here’s my basic cheatsheet:

CAT5 - 100Mbps, 100 Mhz

5e - 1Gbps

6 - 1Gbps (10Gbps < 55meters), 250 Mhz

6a - 10Gbps, 500 Mhz

[2nd attempt at posting. Timed out earlier.]

Cablek has a nice primer on their website on it

https://www.cablek.com/technical-reference/cat-5---5e--6--6a---7--8-standards

the connector types used are also a part of the spec for example CAT7 standard cannot be achieved with an RJ45 (at least by the book) Though you might still use CAT7 rated cable for the additional interference resistance at longer distances with RJ45 connectors.
