Exclusive: PS5 might feature discrete graphics, not a slower APU

So everyone is clear. An APU is not always automatically slower than a Discreet GPU. APU's can actually be faster.

What did Cerny actually do though? He is a greaty speaker, I give him credit for that and he understands hardware, once you step around the product-selling spin.

Let's think of the possibilities: PS5 runs a Vega-based graphics card that we've been hearing about in the GTX 1070 level performance range
|
So what is being said here is that the Playstation 5 will run with old and outdated technology that isn't even high-end? Ew. Not exactly screaming "Next gen".

Sony would've learned their lesson after the PS4 Pro, as Project Scorpio will slap them all over the place, and I'm sure they don't want that to happen again.
|
What Lesson? The lesson that newer released hardware is faster? That has nothing to do with it being an APU.
The Plastation 3 is the only console cycle where Sony had a power edge over it's competitors anyway for an entire console generation. It didn't amount to much, but it was there.
Sony will do what is the best for Sony, the right hardware that provides the right amount of performance at the right price.

2019 is too soon imo. PS3 and 360 lasted a long time. Give the PS4 and XB1 till 2020 |
PS3 and 360 lated too long. 2019 would be five years... that's long enough.
|
The Playstation 3 and Xbox 360 didn't have mid-generational upgrades, so this is new ground we are walking on.

It'll be based on 7nm AMD Navi

Hopefully it uses something that is also more modern than Navi.

If they don't use an API they will proberbly use a Nvidia GPU someting that mark cerney already said is possible since Nvidia doesn't really deliver amazing CPU performance. |
AMD hasn't delivered amazing CPU performance with Jaguar either.
Cost is ultimately more important in what determines a consoles capability.
I think you meant APU not APU in that context. :P

It's actually 6 years with a late 2019 launch, which is why I think it's happening. 3 years til Pro came out. 3 more years til PS5 comes out. I think we're going to see a 1700 Zen CPU and a Vega 10 GPU, most likely in APU form. There's a chance we get a Zen+ in there and/or a Vega 20, but it's going to come down to cost. If Sony can put them in, with (most likely) 16GB of HBM2/3 RAM, for only ~$425, then they will and launch it for $399.
|
HBM of any kind isn't going to happen with the next gen consoles. It's far to expensive.
GDDR6 will likely be the Ram of choice. And in the right configuration can be faster than HBM anyway.

Sony have always liked dedicated video memory as both Vita and PS3 have separate memory pools this is easier with separate gpu and cpu chips.
|
False. A single memory pool is easier for developers to work with.
bonzobanana said:
Also splitting into 2 main chips makes cooling easier so has thermal advantages. |
Again false. Consoles can have up-to a dozen memory chips. For instance RSX in the Playstation 3 has four 32MB Ram chips each connected via a 32-bit bus for a total of 256MB on a 128bit bus. The rest of the system has a similar configuration with the other 256MB 128-bit bus memory pool.
bonzobanana said:
Cache is slightly less important to the gpu as more likely to be unique data. |
Cache is very important to the GPU. They tend to have allot of it. Especially now with AMD reworking it's ROPs so that they are tied to the L2 cache on the GPU for better deffered rendering performance.
bonzobanana said:
By providing dedicated pools of memory you could much increase overall memory bandwidth significantly over Scorpio. |
How?
bonzobanana said:
Consoles often have many of the same thermal issues as laptops and they often have discrete graphics to get decent performance, its no different to that really. |
Do they? Do they really?
bonzobanana said:
We have seen both ps4 and xbox one run their APU's quite slowly again because of thermal issues, much slower than 360 and PS3 at least for the cpu's, something like 1.6ghz compared to 3.2ghz. Splitting gpu and cpu's will help allow higher clock rates. |
Even with only half the clockspeed it is still faster than what the Playstation 3 and Xbox 360 had overall.
Clockspeed isn't a denominator for gauging performance, the megahertz myth was busted in the 90's.
Jaguar having the clockspeed it does has nothing to do with thermals either, the chip was engineered to be an energy efficient, low clocking part from the very beginning, it even had it's transistor type, layout optimized for that to get as much performance/watt/die size as possible.
The reason why Sony and Microsoft settled on Jaguar was because it was cheap... And it allowed them to sink more of their budget into the GPU, which is the thing responsible for drawing all the pretty pictures on the screen that people like to fap over.
Now you can have high-clocking CPU's in an APU, AMD and Intel have proven it. AMD has Bristol Ridge APU's that would turbo to 4.2ghz.
I do have to ask though, where on earth did you get your information and ideas from?
