Intel video hardware generations
|
|
================================
|
|
|
|
This file summarizes the different generations of Intel hardware, because the
|
|
naming is a bit inconsistent and it's hard to follow which is which sometimes.
|
|
The devices can be referred to by year of introduction, generation number,
|
|
chipset commercial number, or internal codenames.
|
|
|
|
Generation 1
|
|
============
|
|
|
|
These are the i740 and i810 devices handled by intel_810. No further info will
|
|
be provided here.
|
|
|
|
Generation 2 / 2002
|
|
============
|
|
|
|
i830, 845, 85x, 865
|
|
|
|
Generation 3 / 2004
|
|
============
|
|
|
|
This is the first generation to be documented at intellinuxgraphics.org.
|
|
Generation 2 devices are quite similar for the modesetting part, but not
|
|
identical.
|
|
|
|
GMA 900 (i915G)
|
|
GMA 950 (i945G)
|
|
GMA 3000 (946GZ, Q965, Q963)
|
|
GMA 3100 (G31, G33, Q33 et Q35)
|
|
GMA 3150 (Pineview for Atom CPUs)
|
|
|
|
Generation 4 / 2006
|
|
============
|
|
|
|
GMA X3000 (i965G)
|
|
GMA X3100 (i965GM)
|
|
GMA X3500 (G35)
|
|
GMA 4500 (Q43, Q45)
|
|
GMA 4500M / 4500HD (GL40, GS45, GM45, GM47)
|
|
GMA X4500 / X4500HD (G41, G43 (X4500), G45 (X4500HD))
|
|
|
|
Generation 5 / 2010
|
|
============
|
|
|
|
Westmere / Clarkdale, Arrandale / Iron Lake / Ibex Peak
|
|
|
|
Switches from the traditional northbridge / southbridge to the new
|
|
"platform control hub" design. Essentially, most of the northbridge functions
|
|
are now directly in the CPU package.
|
|
|
|
Generation 6 / 2011
|
|
============
|
|
|
|
Sandybridge / Cougar Point
|
|
|
|
The northbridge and CPU are now even on the same die.
|
|
|
|
Generation 7 / 2012
|
|
============
|
|
|
|
Ivy Bridge / Panther Point and Haswell / Lynx Point
|
|
|
|
A lot of the video output hardware is moved from the northbridge (CPU) to the
|
|
PCH. This makes sense because it allows to match the PCH chipset (soldered on
|
|
to the motherboard) with the video ports (also soldered there). Otherwise, the
|
|
CPU generation would define which ports are usable or not.
|
|
|
|
This impacts several things in the modesetting sequence, as well as the address
|
|
of the registers which are moved.
|
|
|
|
This is also the first generation to support 3 independant displays, which
|
|
also impacts the register layout in many places.
|
|
|
|
Generation 8 / 2013
|
|
============
|
|
|
|
Broadwell / Wildcat Point and Braswell
|
|
|
|
Generation 9 / 2015
|
|
============
|
|
|
|
Skylake / Sunrise Point, Apollo Lake, Kaby Lake / Union Point
|
|
|
|
Generation 10
|
|
=============
|
|
|
|
Cannon Point / Coffee Lake
|
|
|
|
Generation 11
|
|
=============
|
|
|
|
Ice Lake
|
|
|
|
Generation 12
|
|
=============
|
|
