INTRO

The Playstation 5 has finally been revealed by Sony! Well, some of it, anyway. Mark Cerny, the lead system architect for both the PS4 and the PS5, has gone on stage for almost an entire hour and has talked very in-depth, just the way we like it, about all the main specification of the PS5. So, without any further ado, here are 25 interesting facts that you might not have known about the PS5!

1) World’s Fastest SSD

At Number One, the PS4 came with a traditional HDD. The PS5 now comes with an SSD. But this is not your usual SSD. This is actually a custom SSD module made by Sony, that is ridiculously fast. It turns out that this SSD module that Sony custom made for the PS5 is actually the fastest SSD module in the world right now!

2) 110 Times Faster

Ok, but how fast is this internal storage of the PS5? The PS4 had a traditional HDD, that had around 50MB/s transfer speeds. The PS5 now uses this brand new Custom SSD, which as transfer speeds of 5.5GB/s (or 5500MB/s), which makes it 110 times faster!

A top of the line MacBook Pro, iMac Pro or Mac Pro, which are known to have the fastest SSD modules on the planet right now, have around 3.5GB/s transfer speeds. The PS5 has 5.5 GB/s, a massive improvement over even the fastest SSD modules out right now. But, how is this even possible? Well, the PS5 is now taking full use of the brand new PCIe 4 standard, this is how it can achieve these incredible speeds.

3) Mark Cerny

The guy that was on the stage and talked about the specs of the PS5 and how the entire system works, is none other than Mark Cerny himself. Mark Cerny was the lead system architect for the PS4. He was the main reason as to why the PS4 was so successful when compared to the PS3. The PS3 had this very complex architecture with the Cell Processor, that developers found extremely difficult to develop games for.

The PS4 on the other hand, not only had significantly more power than even its competitor, the Xbox One, but it had a more traditional PC like architecture and it was so much easier for developers to take full advantage of it. All of this was thanks to Mark Cerny.

He was not only responsible for the PS4’s success, he was also heavily involved in the development of some very well known 1st party PS4 titles, such as Ratchet and Clank, Crash Bandicoot, Uncharted Drake’s Fortune, God of War 3, Killzone 3, Knack, The Last Guardian, Knack 2, Spider-Man, Death Stranding and so many more. Not only that, but as an American, he’s also fluent in Japanese and moved to Japan in the 80’s and 90’s.

He’s given tours of their game development studios to Steven Spielberg and Michael Jackson and he’s well known for developing the “Cerny Method’, this is where developers try to complete just a small portion of the game in pre-production fully and from there they can decide if the whole game is worth taking any further. Now, Mark Cerny has also been directly involved with the PS5’s development by being the lead system architect.

4) Massive Freedom for Developers

Since this new SSD is so insanely fast, it brings some massive freedom for developers. For example, because of how slow the HDD was, in some cases developers had to implement a lift, or a very long staircase, or a subway system or something that would allow the game to load a new part of the world or scene in the background. Masking loading times with a subway ride would no longer be required so developers can now design their games much more freely.

5) SSD as RAM

We knew it was going to be fast, but this was totally unprecedented.

Because of that insane 5.5GB/s speed, the PS5 can actually use the SSD as RAM (to some extent) and offload some of the assets onto it, keeping the RAM free for the most important assets. But, how much faster is the actual RAM?

Well, DDR1 memory at 266MHz is around 2.1GBs. DDR2 Memory at 533MHz is 4.2GB/s. DDR3 memory at 1066MHz is 8.5GB/s and DDR4 memory at 2133MHz is 17GB/s. So this SSD, while still nowhere near the speed of RAM, is still close in performance to DDR3 memory, which is still very impressive.

6) Kraken Compressions

Mark Cerny did mention that they’re using something called Kraken Compression to reduce the size of the games by 10%. Not only that, but he also mentioned, last year, that the PS5 will allow you to install or uninstall specific portions of the game. For example, in a game like Modern Warfare, you will be able to just install the campaign and then uninstall it once you’ve finished playing it, then you can install the Multiplayer and so on. This will save a ton of space by letting the user install just what he or she wants, in a game.

7) SSD Size

We know that this SSD is fast but how big is it? Well, Mark Cerny hasn’t really said that but, in a slide from yesterday’s livestream, he did mention 825GB as an example for the size. This points to a 1TB SSD, but the usable capacity for developers would indeed be smaller, at around 825GB, due to formatting and the space that the OS will require.

8) SSD Expansion

The good news is that you will actually be able to expand this 1TB of internal storage in a pretty genius way. While Microsoft will be selling their own 1TB Proprietary SSD modules for the Xbox Series X, Sony will actually allow you to install any m.2 Drive that you can buy off of Amazon. However, they will need to be at least as fast as the internal storage, and they will need to be PCIe 4 modules. At the moment, there are a few of these drives but the speed varies. Mark Cerny did mention that we should wait until manufacturers start producing these drives, but once they do, you would be able to buy any 3rd party drive as long as it matches the 5.5GB/s speed of the PS5 SSD.

9) Weaker than Xbox Series X?

Speaking of the Xbox Series X, now that we know the GPU power of the PS5 (10.28 TFLOPS), it seems like it is noticeably weaker than the Xbox Series X (12 TFLOPS). However, that might not necessarily be the case, or at least not to the extent that it seems.

10) CU & Clock-Speeds

The PS5 has 36 CU’s (compute units) at 2.23GHz. The Xbox Series X has 52CU at 1.82 GHz. Mark Cerny has said that he always prefers a higher clock speed, reason why they decided to go for a lower number of CU, but at the much higher clock speed. We do believe that he does have a very valid point here.

Think of CU as the cores of a CPU, as an analogy. While some applications, like 3D rendering for example, do prefer a high number of cores at a lower clock speed, games in general prefer a lower number of cores but at a much higher clock speed. Usually games don’t need more than 4 cores. Now this is a GPU not a CPU, so things are quite a bit different but, depending on how the games are optimised, a higher clock speed might be preferred in most cases, to a higher number of compute units. So, while the Xbox Series X does look much more powerful, the gap might be much smaller than it looks.

11) Xbox Series X SSD

12) Faster CPU

CPU wise, we finally know the frequency. We now have an AMD CPU, a Ryzen 3rd gen, based on AMD’s Zen 2 x86-64 architecture. Also, we have 8 cores at 3.5GHz. While this is a pretty big improvement over the PS4’s 1.6GHz 8-core AMD Jaguar processor, the Xbox Series X does indeed have a clear advantage in the CPU department, thanks to a 3.8GHz processor, compared to 3.5GHz on the PS5.

13) RDNA2

But, the PS5 does indeed come with AMD’s RDNA 2 architecture (same as the Xbox), which isn’t even out yet for PC. This is AMD’s most advanced GPU architecture, which should hit stores by the end of this year.

14) Legacy Modes

Something pretty awesome in terms of the PS5, are the Legacy Modes. Essentially, the PS5’s GPU can turn off some of the Compute Units and the Clock Speeds, in order to make it essentially identical to a PS4 & PS4 Pro. This means that many PS4 games will be natively supported at launch.

15) Backwards Compatibility

Speaking of this, Mark Cerny said that they tested the top 100 PS4 games and most of them were playable on the PS5, at launch. Without any updates at all required by the developers. That is great, however it does seem like not all the games will work, but a good majority of them should. Of course, if developers do release updates to their games, PS4 games will run at an even higher Resolution and Frame-Rate on the PS5 hardware.

16) Ray Tracing

Just one example of what RTX will bring to Next-Gen Consoles.

Probably one of the biggest new features of the PS5 will be Ray-Tracing. Long story short, this will allow for some significantly improved Lightning, Shadows, Reflections and even Audio will be ray-traced. All of this would make the Graphics and the sound look way more realistic than anything we’ve seen up until this point.

17) Video Memory

Video Memory is also a very important aspect of the next generation of consoles. Mark Cerny has now confirmed that the PS5 will come with 16GB of GDDR6 memory, up from the 8GB of GDDR5 memory that we had on the PS4. Some of this is used for the OS as RAM, some for games and we’ll go through this and how it comes with the Xbox Series X, in a future video. Lots of interesting things to cover there so do make sure that you’re subscribed.

18) Memory Bandwidth

Aside from the amount of Video Memory itself, the Memory Bandwidth is also extremely important. We now have 448GB/s of bandwidth, up from 176GB/s, which is a gigantic upgrade.

19) Advanced API’s and Tools

Sony will be giving developers a few API’s and tools that will make a big impact on their games. We have a new Geometry Engine, we have Primitive Shaders, which are essentially a heavily improved version of the Shaders that we have now. Long story short, a higher resolution on 3D textures (rocks and bumps in roads etc). These will look much more realistic on the PS5. Primitive Shaders aren’t something that developers need to use out of the gate, but if they choose to, they can take full advantage of them and heavily improve the realism in games.

20) Cooling System

Now, one of the mean new features of the PS5, will be its cooling system. We’ve all seen those insane looking Dev-Kits, we were actually the first to reveal the 1st image of an actual Dev-Kit that got sent to us.

21) Design

Mark Cerny did say that they have made a very special cooling system, and thanks to the many reports that we’ve seen that claimed that the cooling system is an extremely expensive component for Sony, it is quite likely we would see a design similar to the DevKit or at least the 2nd leak that we got. This could quite possibly be something that implements a V-shaped cooling system and still has a modern design.

22) Tempest Engine

We got a taste of 3D Audio with the PS4, but Sony are really pushing the boat out for the PS5

Mark Cerny did indeed talk a lot about their new Tempest Engine. Essentially, what this is, is a single Compute Unit dedicated for the new Audio Engine. We would be getting 3D Audio at the hardware level. This means, that no matter what headphones you have, you would be getting 3D audio, just like you used to on the PS4 with Sony’s 1st party 3D headphones. Not only that, but Sony is currently working on optimising the Tempest Engine for speakers as well as sound-bars, in order to be able to provide 3D audio, even if you’re not wearing headphones. This is unfortunately much more difficult to do, but to some extent at least, it is doable.

23) Release Date

If you’re wondering when the PS5 is getting released, this will indeed be by the end of the year. We have had many leaks saying that the actual release date would be in mid-November.

24) Price

Price-wise Sony hasn’t said anything about the PS5, but this is expected to cost $500 in the US.

25) Selling at a Loss

However, because of the sheer amount of high end components that Sony is packing into the PS5, we’ve seen reports that they are really struggling with the price. In fact, Sony might even have to sell the PS5 at a loss at first, in order to sell it at that $500 price point that many consumers would buy. They will be making their revenue back from the actual sales of games but, when it comes to the actual hardware, they might be at a loss.
