Next-gen PS5 and next Xbox speculation launch thread - MY ANACONDA DON'T WANT NONE

Official PlayStation 5 Specifications Revealed so far:
  • 7nm 8 Zen 2 Cores (Unknown clock-speeds, and whether it will have SMT)
  • 7nm AMD Radeon NAVI GPU (Unknown clock-speeds and core count)
  • Ray tracing support (Hardware-accelerated? Software-accelerated?)
  • 8K Output support
  • SSD (allegedly faster than PC solutions available at the time of publication)
  • PS4 Backwards compatibility
  • Not coming 2019
Revealed by Mark Cerny in Wired Interview

Official Xbox Scarlet Specifications Revealed so far:
  • Zen 2 CPU (Unknown clock-speeds, and whether it will have SMT)
  • NAVI GPU (Unknown clock-speeds and core count)
  • GDDR6 Memory (Spies speculate that it has 12 memory chips, pottentially giving it a 384 bus-width and total of 24GB of memory with 672GB/s of memory bandwidth)
    On the topic of this, in 2016 Microsoft showcased a render of the Xbox One X's board while the system was in development and the number of chips were able to match up with the number of chips the retail system has. Of-course, things may be subject to change so this is somewhat speculation included with officially revealed information.
  • Up to 8K resolution support
  • Up to 120 fps support
  • Ray tracing support - Hardware-accelerated
  • Variable Refresh Rate Support
  • SSD (Can be used as virtual memory)
  • Backwards Compatible

Patents
Becareful with patents, don't take everything you read in a patent to mean that it will be implemented in a company's next product, as some things that companies patent don't always come to fruition.

PS5 - a patent dive into what might be the tech behind Sony's SSD customisations (technical!)

The TLDR is

- some hardware changes vs the typical inside the SSD (SRAM for housekeeping and data buffering instead of DRAM)
- some extra hardware and accelerators in the system for handling file IO tasks independent of the main CPU
- at the OS layer, a second file system customised for these changes

all primarily aimed at higher read performance and removing potential bottlenecks for data that is written less often than it is read, like data installed from a game disc or download.

Other information regarding the PlayStation 5:

Richard Geldreich:
"Next-gen console games will be all about extremely efficient and optimized geometry and texture data distribution. I saw a public Sony demo that used extreme amounts of texture and other content in a dense city. Microsoft will have to keep up."



Next Xbox rumours:
There's rumoured to be two models, Codenamed Lockhart and Anaconda, with one being more powerful than the other.

Windows Central: Xbox 'Scarlett,' 'Anaconda' and 'Lockhart:' Everything (we think) we know

What we know about RDNA:
  • Allegedly a new 7nm GPU architecture
  • New Compute Unit Design with improved efficiency and increased IPC allegedly offering 1.25x performance per clock
  • Features higher clock speeds and gaming performance at lower power requirements
  • First RDNA GPUs available in July, starting with the RX 5700 series GPUs
  • An RX 5700 GPU was shown to perform 10% faster than the RTX 2070 in Strange Brigade (However this game is known to perform better on AMD GPUs than NVIDIA GPUs, so it doesn't necessarily tell the whole story performance-wise)


RDNA Details:
The RX 5700 GPUs are not necessarily what's going to be used in the PS5 and Project Scarlet.
So far no ray tracing capabilities have been confirmed for these GPUs.

RX 5700 XT
Compute Units: 40
Core Count: 2560
Teraflops: Up to 9.75
Memory: 8GB GDDR6

Boost Clock: Up to 1905 MHz
Game Clock: 1755MHz
Base Clock: 1605MHz

RX 5700
Compute Units: 36
Core Count: 2304
Teraflops: Up to 7.95
Memory: 8GB GDDR6

Boost Clock: Up to 1725 MHz
Game Clock: 1625MHz
Base Clock: 1455MHz

RDNA GPU performance speculation
On the topic of IPC improvements, here is an RTX 2070 review with Strange Brigade tested on Page 2

Nvidia GeForce RTX 2070 Review: Page 2 - Shadow of the TR, Strange Brigade, Monster Hunter: World

It would be ideal to pull results from a review of the RX 5700 GPUs when they release but for now all we have to work with is the numbers AMD have given us, the RX 5700 GPU was shown to be performing around 10% faster than the RTX 2070 in Strange Brigade. Looking at TechSpot's review of this GPU it appears that the RTX 2070 performs within 10% of the Vega 64, so a RX 5700 should theoretically perform similar to, or greater than an air-cooled Vega 64 GPU.
In Anandtech's review of the Vega 64 it appears to hold an average clock speed of 1523MHz out of the 8 games they tested, which means that it's theoretically offering 12.4 teraflops of performance.

I don't recommend using a single game as a point of reference for determining the performance of the RX 5700, but it could be that the RX 5700 offers Vega 64 performance. Presuming RDNA's 1.25x performance per clock translates across to these workloads, then it could be estimated that the RX 5700 in AMD's testing is a around a 10 TF GPU, offering the performance of a 12.4 TF Vega GPU. However my calculation may be off so take this with a grain of salt.
If anyone has anything to add to this then please do!

RDNA die sizes have been estimated to be around 255mm2 and 275mm2, this could mean that the RX 5700 offers Vega 64 performance at around, or almost half the size. As the Vega 64 is a 495mm GPU.

Wait, shouldn't it be "It's in the RDNA"?

Also, super dissapointed no references to crazy pastebins in the title.

At any case, awesome OT, OP :D

The most interesting rumour imo is about full RDNA coming in 2020 & the 5000 series of Navi being a hybrid of RDNA & GCN.

So this thread might actually have some real info in it with E3 coming up. It'll be worth it for 2 reasons, one to compare what the consoles have to offer and second to see some massive melt downs. Devil..:)

The specs are great, but I wonder about the cooling tech they will use. I want both machines to be as quiet as possible. Xbox One X does a great job being almost silent. Well, apart of some games that make the fans go wild like Wolfenstein II: The New Collosus and Red Dead Redemption 2. At least from my experience.

New Thread Checklist:

Navi is Sony exclusive
SSD's are a game changer
Xbox is using Vega
2 SKU's is a mistake
Streaming won't take off
Pastebin is the law
This thread will tera-flip flop for the next year and a half

Did I miss anything? :)

Xbox is using beyond Navi.
Microsoft has more money than Sony.

Well a different thread is entertaining the rumour that Scarlet wouldn't have any first party next gen exclusives on release because all its games need to run on Xbox One hardware. But I guess we can leave that out unless it gets confirmed later.

RDNA will evolve, like GCN did.

Maybe RDNA will be at 1.1 next year - but if 1.0 is actually a close-ish descendant of GCN (which wouldn't be too surprising), then I'm not sure 1.1 will necessarily differ substantially in that regard. It begs the question of what 'full RDNA' means - is it full when we're at 1.3 or 1.4 in a few years time? Or when we're at 1.1 in a year? Who decides?

(Which is all to say, these labels might be a bit arbitrary. And I think we kind of just have to take AMD's labeling and decisions about where to demarcate things at face value.)

VR is at it’s absolute infancy still, but it is undoubtedly here to stay. There’s an amazing amount of innovation happening in the VR space and it’s only going to expand once core issues are taken care of.

I currently have no room for full-scale high-end VR in my home, but having experienced proper VR gaming truly convinced me of the fact that it’s without equal. It takes everything I love most about gaming (immersion, adventure, storytelling, interaction) and enhances it to a ridiculous degree.

I’d say going into next-gen without at least a proper plan for future VR support is a fool’s errand. You need to be proactive in that regard because it’s an untapped market with ridiculous potential for gaming. So it would make alot of sense to be at the forefront of it all.
The problem with VR is how expensive VR sets are. They will never become mainstream unless the cost factor comes down. It is easier to put big money on a project that will be available to tens of millions or hundreds (given the stance Microsoft has taken on PC) than it is to put money on an extension that may not see 10 million in sales.

Many have an issue paying full price for a console......how much more when they have to pay $400 on a device that does not gain as much in quality content?

I've been out of the Xbox loop for a while - Is it feasible they announce/reveal their new hardware next week at E3?

Isn’t the thread title wrong? ”Next Xbox” is correct but “next gen PS5” is kinda wrong. It should be “Next gen PS”
PS5 alone stands for the next gen part, we don’t have a current gen PS5!

Ok THIS TIME Microsoft will announce the Next Gen Xbox before this thread dies.

I was a month too early last time...

They could, but probably not much more than what Sony already revealed about PS5. Basically, confirm that the machine exists and maybe adjust any message to control what people hear from all the devkit leaks that would soon be coming.

Oh, yeah, I saw a post a while ago saying that a studio got their PS5 devkits already but not a XboxNext kit. I don't remember where so can't check. But that might suggest third parties haven't got their Xbox dev kits yet. And that might explain why MS is officially announcing their console later than Sony.
Everyone know that dev kits to third parties cause leaks, so when you do that you had to control the PR narrative. Sony did that recently, so it might be Microsoft's turn now.

It could just mean better performance at basic, but some people were thinking full RDNA will have ray tracing, which might makes it's way into PS5/X2.
