Chart
4 figures from 4 machines, spanning 2000 to 2025. The lowest memory bus width here is 128 bit (Valve Steam Deck, 2022) and the highest is 2560 bit (Sony PlayStation 2, 2000). That is a range of about 20× within one comparability group; the figures are plotted in bit. Points use the release date of the machine the figure belongs to. The table below lists absent figures with their recorded reasons.

| NVIDIA GeForce GTX 1080 NVIDIA GeForce GTX 1080 frame buffer | May 2016 | 256 bit | Vendor-rated | |
| Valve Steam Deck | February 2022 | 128 bit | Vendor-rated | |
| NVIDIA GeForce RTX 5090 NVIDIA GeForce RTX 5090 frame buffer | January 2025 | 512 bit | Vendor-rated |
Why this chart holds one group only
Every point on a chart is implicitly compared with every other point on it. This chart uses one comparability group: one metric, one device scope, one method . There is no chart of all clock frequencies over time because they are not one quantity.
Points use the release date of the machine a figure belongs to, including figures recorded against a part. A release date applies only to a machine that shipped. What this metric measures.
