There has been a lot of leaks/rumors lately about desktop zen2 and Navi. It happened yesterday from a youtuber named adoredtv, he leaked the entire Zen 2 lineup along with it's Apu's, he also leaked Navi cards. One thing to note is that adoredtv think all these are chiplet designs but his source would not confirm this.
Now you might be sceptical but this information has been confirmed by Kyle Bennet he knows everything but says there's some minor errors. I'll post the most interesting stuff:
Ryzen 3 3300G - 6C/12T/Navi 15CU - Base Clock 3.0 - Boost Clock 3.8 - TDP 65W - $129
Ryzen 5 3600G - 8C/16T/Navi 20CU - Base Clock 3.2 - Boost Clock 4.0 - TDP 95W - $199
Radeon RX 3060 (Navi12) $129 - 4GB GDDR6 - 75W TDP (Radeon 580 performance)
Radeon RX 3070 (Navi10 or Navi12) $199 - 8GB GDDR6 -120W TDP (Vega 56/geforce 1070 performance)
Radeon RX 3080 (Navi10) $249 - 8GB GDDR6 - 150W TDP (geforce 2070 performance)
This is really bad news for us, I'm expecting the ps5 to have a Ryzen 3 3300g chip but with a cut-down radeon 3080 gpu. We have gone from expecting ryzen 2700 cpu performance to ryzen 2600 performance and 30%+ performance of a geforce 1080ti to vega 64/geforce 1080 gpu performance.
SHORT VERSION:
Expect a 6core zen2 cpu (2 cores will be deactive for better yields) with about ryzen 2600 performance and a gpu with geforce 1080/vega64 performance. The information about desktop zen2 and navi should be confirmed at Ces between 8-12 jan if true or not.
I'm slightly sceptical what cpu we will get as it will probably be very hard to do backwards compatibility for PS4 games with only 6 cores.

No it isn't.... and for a lot of reasons.
- You are looking at retail prices. Sony is not buying these chips using retail pricing, they buy as an EM and use bulk contract pricing. They can basically take a $200 CPU/GPU and get them from AMD at under $100 each.
- These prices are expected to be for 2019. The console doesn't come till 1H 2020 at the earliest. So even at EM pricing sony is not going to be paying what an OEM would have paid in 2019.
- You are also ignoring the most obvious fact. We have already seen what can be accomplished from a die shrink having gone from the PS4(28nm) to the PS4pro(16nm). While the CPU was left untouched the CU count in the GPU doubled from 20CU in the PS4 (2CU for redundancy) to 40CU in the PS4pro (4CU for redundancy). And the overall die size dropped from 348mm2 in the 28nm PS4 to 321mm2 in the 16nm PS4pro.
The takeaway here is that going from 16nm to 7nm and keeping the die size at around 350mm2; sony will at the very least be able to fit a GPU with 80CU - 88CU and ryzen CPU in there too. At the very least.
- Now also consider the efficiency and thermal gains on a smaller manufacturing node too. Which means that clocks can be higher than at least what we have now. But also lower than the advertised margins from what the chips are based on (because consoles and no room for throtling) so think around 20-30% slower clock speeds. So if the parent CPU runs at 3GHz expect it to run at around 2.5Ghz in the console....etc.
- Lastly..... custom chips and hardware especially when ordered in the scales of consoles is a totally different kinda business. But lets talk about costs here. If sony intends to come in at $399 then expect the APU budget to be no higher than $150 (again remember the PS4pro at 16nm and its APU budget was around $130). If they are looking at a $450/$499 price point then the APU budget can be anywhere from $200 - $250.
Either way you are looking at a massive step up from what is currently in the Pro/X.

One of the points made about AMD's supposed new design, is that they will likely use 7nm chiplets and interconnect them all through a 14nm I/O die and an interposer. It's explained why this makes sense through comparing yields for chiplets vs APU's and the ability to have many different SKU's, mixing and matching chiplets and I/O dies without having to design a bunch of custom APU's or chips in general. This would likely make it extremely easy to offer an upgraded console at launch or down the road. Just swap out the base GPU chiplet for an upgraded one, maybe even the CPU. No need to design another new custom APU. This should also help in terms of thermals as well.
By using only 6 cores, they could get away with higher clocks which are more important for CPU's when gaming. The 3.0GHz range, give or take, with 6 Ryzen cores, will be plenty to hold 60fps. It'll likely be an 8 core die with one core disabled and the 7th core will be OS only. That would leave 6 dedicated cores for games, which is all the PS4 had for a couple of years before PS eventually opened up the 7th core to devs for games. MS waited almost as long to open up XB1's 7th core as well.
