Digging in the data sheet I found the CAPID0 register which does

we invent a new PCI device ID for this every generation (0x0EC3 in
Ivy Bridge, 0x2fc0 in Haswell, 0x6fc0 in Broadwell). The offset
has stayed at 0x84 through all this.
I don't think that hunting the ever-changing PCI-id is a
good choice ...
Right :-\
the "E5/E7" naming convention has stuck for
four generations[1] (Sandy Bridge, Ivy Bridge, Haswell, Broadwell).

[1] Although this probably means that marketing are about to
think of something new ... they generally do when people start
understanding the model names :-(
Yeah, customers shouldn't slack and relax into even thinking they know
the model names. Fortunately there's wikipedia...
Thanks.
