Intel Core i7-8809G "Kaby Lake + Vega" MCM Specs Leaked Again, Indicate Dual IGP
Intel revealed specifications of its upcoming "Kaby Lake + AMD Vega" multi-chip module, the Core i7-8809G, on its website. A number of these specs were already sniffed out by Futuremark SystemInfo, but the website sheds light on a key feature - dual integrated graphics. The specs sheet confirms that the chip combines a 4-core/8-thread "Kaby Lake" CPU die with an AMD Radeon RX Vega M GH graphics die. The CPU is clocked at 3.10 GHz, and SystemInfo (from the older story) confirmed that its Turbo Boost frequency is up to 3.90 GHz. The L3 cache amount is maxed out a 8 MB. The reference memory clock is set at dual-channel DDR4-2400. What's more, the CPU component features an unlocked base-clock multiplier.
Things get interesting with the way Intel describes its integrated graphics solution. It mentions both the star-attraction, the AMD Radeon RX Vega M GH, and the Intel HD Graphics 630 located on the "Kaby Lake" CPU die. This indicates that Intel could deploy a mixed multi-GPU solution that's transparent to software, balancing graphics loads between the HD 630 and RX Vega M GH, depending on the load and thermal conditions. Speaking of which, Intel has rated the TDP of the MCM at 100W, with a rider stating "target package TDP," since there's no scientifically-correct way of measuring TDP on a multi-chip module. Intel could build performance-segment NUCs with this chip, in addition to selling them to mini-PC manufacturers.
Specifications of the RX Vega M GH continue to elude us. All we know is that it has its own 4 GB HBM2 memory stack over a 1024-bit wide memory interface, ticking at 800 MHz (204.8 GB/s memory bandwidth), and a GPU engine clock of 1.19 GHz. Even if this chip offers performance in the neighborhood of the discrete Radeon RX 570 4 GB, it should make for a killer entry-level gaming solution. Motherboards based on it could quickly capture the gaming iCafe, entry-gaming PC, and performance AIO markets.

These GPUs will not work together on rendering the video output - that would most likely be a mess.
The system will switch between them depending on the rendering load (like it would on a laptop).
And it's no surprise, since AMD GPUs are way too power hungry in idle. This would not be acceptable in a NUC / ultrabook.
The more interesting scenario is when this MCM uses both GPUs at the same time: Intel IGP for video and Vega for software acceleration - I'm rather excited. It's the prince that was promised :-)
Most of the leaks/speculations so far put it in the range of 500 shaders. Which puts it around RX540/550. RX550 has a TDP of 50W so that matches as well.
There have been some photos around of this thing and judging just from the size of the die , it should have at least 1536 shaders.

Most 1070-80ti use between 10-16watts in idle depending on model.
Did it not adequately address your concerns regarding vegas idle power draw , equivalent equipment and all ,same ish idle power??
In general they'll have to be on the ball to hit performance metrics within their allowed power budget that i think we agree on.
Man... you just went berserk about it! I didn't say Vega draws more than Pascal. I didn't mention NVIDIA at all. You're the one who started comparing to "equivalent equipment". :-D
Few days ago someone told you that you're coping very badly with any AMD criticism and it makes discussing difficult, but these few posts were just on another level! :roll:
I just see the trends you see in others just different , always spouting neg stuff about particular parties ,all a bit dull to me.
You see i don't waste too much time bad mouthing what i don't like but im happy to discuss what i perceive as good in technology and for it's future.
And I'm not keen on Google's great flock if im honest.
Let bygones be bygones?
