Thanks for asking.
The first stable XenGT release was in early 2014 and based on 4th gen Core processor (code
name is Haswell) which was the latest Intel platform at that time.
In Q4 2014, we PoC (proof of concept) KVMGT on 4th gen core (Haswell) by leveraging XenGT
In April 2015, the first official KVMGT was released out based on 5th gen core (code name:
Broadwell) which was the latest Intel platform in 2015.
There're 2 reasons why KVMGT skipped Haswell platform (4th gen) official support:
1. Schedule reason. We want KVMGT features on par with XenGT as soon as possible, so
we decided to achieve this goal from Broadwell (5th gen).
2. GPU architecture changes. The GPU architecture evolved a lot from Haswell to
Broadwell, since KVMGT was a new project, we decided to make Broadwell as KVMGT's
In short, KVMGT and XenGT use same code base, have same feature set and they have same
CPU/GPU requirements. KVMGT skipped 4th gen Core platform because of project execution

Subject: [iGVT-g] KVMGT vs XenGT on Haswell processor
I was looking at the 2016Q2 release notes for both XenGT and KVMGT and noticed that KVMGT
mentions the 5th gen Core processors while the XenGT version mentions the 4th gen Core
processors as the minimum. Does the KVM version have a higher CPU requirement or is it a
