Backward compatibility of DIM
[edit]DMI 2.0 and DMI 3.0 is Are backward compatible? — Preceding unsigned comment added by 181.47.181.53 (talk) 22:39, 16 November 2016 (UTC)
Speed of DMI
[edit]When looking at http://www.intel.com/design/chipsets/embedded/945g.htm, you can see that the DMI speed is 2GB/s (1GB/s per way). In addition, 4x PCI-e 1.x is 1GB/s (4*250MB/s). You need PCI-e 2.0 to get 2GB/s out of 4 lanes. What am I missing? --debackerl (talk) 17:35, 10 September 2009 (UTC)
- 4x PCIe 1.x is also 2GB/s; 1GB/s per way. MatthewWilcox (talk) 13:34, 27 January 2011 (UTC)
Mac mini 2018
[edit]The Mac mini 2018 is based on Coffee Lake (i5-8600 with CM246 in a mid-range configuration), and the Intel datasheet for this processor states "8 GT/s DMI3".
So I'm guessing DMI 3.0 is supported for most chips since Skylake, and that this page could use an update. — MaxEnt 18:52, 10 November 2018 (UTC)
Not a serial interface
[edit]- @奧田95: a serial data communications interface has only a single connection for the data and the data passes on bit at a time, serially. By contrast, a parallel communications interface passes bits on two or more connections in parallel. See Serial communication. Please find a reference that states that DMI is a serial interface, because it is not serial by the usual definition. -Arch dude (talk) 16:26, 21 March 2021 (UTC)
