Early rumor :

- PS5 will targeted for 500 USD price  and  a monster that can run games at 4K  60 fps https://www.reddit.com/r/Amd/comments/9yl7zy/ps5_rumored_to_use_8core_ryzen_cpu_cost_500_and/

- PS5 will be suing Ryzen CPU http://gametyrant.com/news/ps5-rumors-new-console-to-use-8-core-ryzen-cpu

- Navi 10 rumored to be as powerful as 2080 RTX https://www.notebookcheck.net/AMD-Navi-10-now-rumored-to-rival-RTX-2080-at-the-highest-end.376256.0.html

- PS5 rumored to be using Navi 10 https://www.gaminginstincts.com/rumor-ps5-specs-leaked-8-core-ryzen-navi-10-lite-gpu/

                         My take on this rumored, probably the spec is close to the truth and because it was also leaked by the same forum who leaked Wii U spec and so far the spec is inline with all the early rumored spec. Also Navi 10 supposed to replace Mid class GPU from 2016 and will bring new 7 nm node chips and gaining 2 times chips density with the same price and 1,35 performance increase with the same power. 

Update: New rumor just came ,

it said PS5 will be using Navi 9 ( a cut down version) , will have 4697 sp , a cut down 384 bit bust size so it will be 320 bit, and will be using 2.2 Gbps GDDR6 speed .  Will be equal or more to RTX 2080. 

New rumor just came from Resetera Forum from Jason Schreier: Sony will and Microsoft aiming more than 10,7 teraflop that google has with their Stadia performance.  https://www.resetera.com/threads/rumor-next-gen-consoles-coming-2020-sony-microsoft-are-aiming-higher-than-10-7-teraflops-gpu.107952/

if true, consider me hyped.

More believable than a SSD I guess.

Good, that'll hopefully mean that we'll be able to finally see games actually making proper good usage of more than 2 cores and all 16+ threads in the future going forward for other hardware (Looking at you ESO and your 2 core 2-4 thread crappy support). 

Ok, just dived deeper and it is copy pasted from the same rumour, AMD Gonzalo. If true, it's 95W TDP is not going to give you that GPU grunt.

PS4 pro is 330W TDP , Xbox One X is 260W TDP. Original PS4 is 200W TDP . 

Also don't forget it will be using 7nm node size and double the amount of CU and shaders on PS4 pro at least and will have 1.35 performance boost with the same TDP 

Hope PS5 has proper support for PCI Express NVMe SSD's (for those who wish to upgrade )

I hope also, but probably it will just be a SATA 3.0 

Whoa, this is gonna be a monster of a home console if true.

I do not take rumours seriously, neither should you. You also need to research GCN limitations
