A 16GB system is what I expect from a console. That would fit nicely with a 16GB consumer grade PC card (a Titan would probably have more, but consoles won't [and shouldn't] ever strive for that).

It depends on if they use only GDDR or a mix as Intrinsic has suggested. 16GB GPUs should be pretty normal by 2020, and that is just VRAM, not to mention the additional 16GB or much more DDR a PC would have. I can see 24GB GDDR with 8GB DDR, or just a single 32GB GDDR pool. This is total system RAM, not just VRAM.

Good thing you said "consumer".
Because there were actually GPU's that had 12GB of GDDR5 memory in 2013.

Either way, I have already broken all that down in one of my prior posts anyhow.

I'm just looking at the layouts possible, and thinking about how things would play out for another 7 - 10 years. I expect PS5 to have an SSD, and preferably it will be a M.2 NVMe SSD.

Mechanical Disks still have a massive Price/Capacity advantage over NAND based approaches, consoles are all about being cost effective first remember.

If they can't deliver a next gen Memory and Storge set up, they shouldn't even release a PS5 yet. If they launch PS5 next year or 2020, with 16GB of RAM and a HDD, they are going to get steam rolled by Xbox and set top boxes. Apple and Amazon will have no problem putting out Apple TV and FireTV devices a year later, that completely trash PS5 at a lower price.

There are still massively faster mechanical disks than what we saw in the Playstation 4/Xbox One devices, they aren't SSD speeds... Sure. - But don't discredit them just yet, there is still a big amount of room for improvement on that front.

Apple TV and the like tend not to have monolithic GPU's either.

Gamersnexus did an article for GDDR prices recently (he's a trustworthy guy), if anyone interested. This is based on his insider sources.

He isn't actually wrong, but he also doesn't paint the entire picture.
Also. Regardless of Gamersnexus's track record... You never place all your eggs in one basket, otherwise you will end up with egg on your face, it is always better to get more than one source.

Also... Down the bottom he iterates (And what me and CGI have been trying to hammer down) is the issue of cost.
And specifically... How costs may actually remain stagnant or possibly even increase... Heck he even mentions that Micron is now going to focus on profits rather than Marketshare, which just says it all, doesn't it?

Not to mention DRAM manufacturers will often retool and focus on higher profit NAND which is seeing constant increases in demand, which means less DRAM product in the channels, thus keeping prices high.

It's a shit situation... Back in 2010 I could buy 32GB of Ram for like $180 AUD.
Today? $500 AUD.

Simple: cost. That one little nagging thing that people have been skipping over the entire thread. Next gen console =! having the most next gen parts one can find. PC has always lead in hardware. No reason to expect that to change.

Something like a Titan X (Pascal) would be a next gen part for a console, despite the fact that there are Titan Xp(s) and the Titan V out there. Cost is why that wouldn't happen. 

AMD needs to invent the GPU first. lol

Their fastest part is a competitor for the Geforce 1080... But will also not happen for a console because of how large, hot and power hungry Vega 64 is.

This article is looking at (1GB) GDDR5 vs (1GB) GDDR6 Modules. PS5 will be using (2GB) GDDR6 Modules, which will offer a nice savings per GB.

Not to mention that 4GB GDDR6 will be rolling out in a few years time.

KBG29 said:

The other Option, where it would be too expensive for Microsoft to double up would be 24GB on a 384 bit bus, using 12 (2GB) Modules. This would probably cost them ~$130. It just comes down to whether more RAM or More speed is going to be optimal to create balance with the rest of the system they are designing.

 

I think we can confidently say that in a non-Premium console... They will stick with a 256bit memory bus as that offers the best price/performance.
Larger the memory bus the more traces and thus layers you require on the motherboards PCB, the more complex the memory controller and power delivery.

Which is fine for a $650 AUD Xbox One X, but not fine for a $299 AUD Xbox One S.

But right now ethere are leaks already of a version Nvidias next GPU using 12GB of GDDR6. And I am certain before the end of next year we will see at least one GPU pushing 16GB of GDDR6.

nVidia does employ 192/284bit memory buses more often than AMD though, so 12GB for the next nVidia GPU wouldn't be out of complete expectation.

Got to be quick, but I think 32GB on a 256 bit bus is a good choice for the base PS5. 48GB on a 384bit bus would be a great mid gen update.
