Welcome back to the ultimate comparison between the PS5 and the Xbox Series X, based on everything that we know so far. We uploaded PART 1 of this comparison back in January. In that video, we talked about the CPU differences, the GPU, the Resolution, the Frame-Rate and the in-game Graphics.

This is PART 2 of that comparison, and here we will be covering the RAM, the SSD and any Special Features that both of these consoles will come with, alongside any other recent leaks since our last video.

It seems like the Xbox Series X will be a bit more powerful than the PS5. The CPU will be pretty much identical between the two, but the GPU will be slightly more powerful on the Xbox. The Series X would have around 12.2 TFLOPS of raw GPU performance, compared to around 9.2 TFLOPS on the PS5. These are the calculations that DigitalFoundry made based on the recent AMD APU leaks from a few weeks prior, this will very likely be the case with the final unit.

However, this is mostly because Microsoft will have two models of the Xbox, the low-end ‘Lockhart’ and the high-end ‘Scarlett’ (which will be more expensive than the PS5).

RAM

The Xbox Series X may dedicate more of its RAM to the OS than the PS5, but there’s still plenty left for developers to use.

Unlike PC’s where we have separate Video Memory (GDDR) and System Memory (DDR), consoles only have Video Memory, which the Operating System (OS) gets to use a chunk of. For example, on the PS4 Pro, we have 8GB of GDDR5 memory, out of which only 1GB is allocated to the OS, while the remaining 7GB are used by games. On the Xbox One X, we have 12GB of GDDR5 memory, out of which 3GB are used for the OS and 9GB are usable by developers, in games. When it comes to next-gen, both the PS5 and the Xbox Series X are said to come with 24GB of GDDR6 memory.

When it comes to how much of this 24GB of GDDR5 memory would be dedicated to the OS, and how much can actually be used by developers, we don’t yet know. It really depends on how both companies approach their new OS on the next-gen consoles. If both companies follow a similar approach to the PS4 and the Xbox One, then Sony should have less memory dedicated to the OS, compared to Microsoft. So developers should have more to play with, in terms of video memory, with the PS5.

In terms of the bandwidth, the Xbox Series X is said to have 560GB/s vs around 512GB/s on the PS5.

Storage

Moving on to the storage, this will actually be the third massive change that the next-gen consoles will be getting, aside from the new CPU and GPU.

The current generation of consoles use plain old HDD’s. Yes, 5400RPM Hard-Drives, which we don’t really even see in laptops anymore, unless you’re looking at the lowest entry models. The HDD inside the current generation consoles only reach speeds of around 50-75MB/s, which is very slow. SSD’s, on the other hand, can reach speeds of up to 550MB/s but are limited by the SATA connector. While m.2 based Flash Storage can reach speeds of more than 3500MB/s.

Luckily, both Sony & Microsoft have confirmed that the next-gen consoles will both be using Flash Storage. Yes, not even SATA based SSD’s, but m.2 based Flash modules that can reach some insane speeds.

Mark Cerny, the Lead System Architect for the PS5, said in a recent interview with ‘The Wired’, that the PS5 will have a storage module that has higher bandwidth than any SSD’s available on PC’s at the moment, which is very interesting. In that famous Spider-Man game demo, a scene that took 15 seconds to load on a PS4 Pro, only took 0.8 seconds with the PS5’s new storage (18.75 times faster). However, if we take the PS4 Pro’s HDD speed, which is about 75MB/s, and multiply that by 18.75, we get 1406MB/s. This is much faster than a SATA based SSD, so this is indeed an NVMe Flash Module, but nowhere near as fast as other flash modules that can reach speeds of over 3500MB/s. Still, it’s a massive improvement over what we currently have now.

In another Spider-Man demo, Sony showed how fast you can actually swing through New York on the PS5 version of the game compared to the PS4 Pro version of the game. The PS4 Pro version ends up freezing once Spidey reaches a certain speed as the HDD simply cannot load the game assets fast enough, while the PS5’s Flash module has zero problems. So, with this new type of storage, not only will the games load up pretty much instantly, you will also be able to achieve much higher speeds in games where…you know…speed is important. For example, games such as Gran Turismo, Wipeout, or any other games that feature a ton of fast moving scenes, will feel so much more immersive with the next-gen consoles. Especially once you keep in mind that 60fps would be the standard with the next gen consoles and both the PS5 and the Xbox Series X will also support 120Hz output.

We have seen a few reports that Samsung would be supplying Sony with their NVMe drives, to be used in the PS5. Samsung did have an internal presentation and one slide did get leaked. We can see that they’re teasing their new generation of NVMe Flash modules that would apparently be used in 2020 consoles. We can also see how the system boot time drops from 49 seconds to around 9 seconds, this would be 5.44 times faster, which looks to be quite low for a Flash module.

So then why did Sony say that their drivers will have a higher bandwidth than SSD’s modules in PC’s today? Well, they were either referring to SATA based SSD where the bandwidth is indeed limited by the SATA connector or they might have been referring to the fact that their drivers would be using PCIe 4.0. This is something that AMD’s current Zen 2 platform supports and that’s where we’ve also first seen PCIe 4 introduced to the market.

Microsoft will also be doing something similar, they talked about this when they first unveiled Project Scarlett. It will feature custom made Flash storage, something miles over what we currently have. A recent leak gives us a bit more insight into the Xbox Series X’s Flash module. A former Phison employee posted a description of his former job, on LinkedIn and it seems like we was working on a specific DRAM-less controller for the Flash module inside the Xbox Series X.

Judging by these specs, the Xbox Series X will only be able to achieve PCIe 3.0 speeds, rather than the 4.0 speeds that Sony are working towards. But, it’s extremely unlikely that Sony will be using drives with read speeds of 6500MB. So even if Sony will indeed support higher bandwidth storage, the Flash modules inside both the PS5 and the Xbox Series X will likely be very similar.

Something pretty cool that you’ll be able to do storage-wise on the PS5, is that you will be able to uninstall certain aspects of the game. So games will be made in such a way so that if you want to only install the campaign, you can do that and then once you’ve finished it, you can uninstall it and install the multiplayer part of the game. This will let you save up a ton of storage. Not only that, but the games themselves will actually occupy less. On the current generation of consoles, because of how slow the HDD’s are, a lot of the games actually had to store multiple copies of textures so that the HDD could load the data from them faster. This won’t be required anymore, with the next gen consoles and so games, at least at launch, will occupy less.

We’ve heard a lot about Sony’s production costs and how material scarcity may end up affecting the RRP, what price do you think the PS5 will launch at?

And speaking of launch, PSErebus (a leaker who’s been very accurate in the past) stated that the PS5 will come with a 2TB SSD and a retail price of $500, 500 euros or £450. That’s pretty impressive! If Sony does indeed ship the PS5 with 2TB of storage, then this would be the dream. We don’t know anything in terms of the storage on the Xbox Series X just yet, but considering that the Series X is expected to cost more, around $600 for the high-end model, it should come with at least as much storage as the PS5 does.

Sony has confirmed that PS5 games will ship on new 100GB Blu-Ray disks and yes, for those of you who are wondering, Blu-Ray drivers are much slower than even a regular HDD, with read speeds of just around 25MB/s. So, with the PS5 and Xbox Series X, the games would not be run from the Blu-Ray disks anymore The only use case for the Blu-Ray disks would be to copy the game direct to your console, as opposed to downloading it from the online store. This is useful if your internet connection is slow and you will also be able to sell the games this way. The Blu-Ray drive will still be required to be inserted into the console, for licensing purposes.

Since the next-gen consoles will rely so much on the internal storage, even games will make full use of this faster storage by enabling a seamless open-world with no loading times at all, both consoles may heavily limit the use of external storage use. At the moment, you can plug in an external HDD or SSD and expand the internal storage that way. It’s a pretty easy and straight-forward process. However, with next-gen, it’s very likely that we would either have First-Party storage modules, or the Third-Party external storage options would need to surpass a certain speed threshold in order for them to be used. Our guess is that only external SSD and m.2 drives will be usable.

Special Features

Finally, the last thing that we want to cover here, is the special features that both of these consoles will have.

RTX is going to be a real game-changer for next-gen consoles and thankfully, it will be on both.

Both Sony and Microsoft have confirmed that the next gen consoles will support hardware based Ray-Tracing. In case you don’t know that Ray-Tracing is, it is pretty much the key selling feature of Nvidia’s RTX series of GPU’s. Real-Time Ray tracing is the most realistic way of casting shadows and reflections in games. This is because, unlike regular reflection and shadow mapping which are always fixed, Ray Tracing involves each light ray being individually cast and reflected to light up a scene, resulting in extremely photo-realistic environments. This might not sound like much but it will make a massive difference in-game.

Additionally, each of the consoles will have some unique features to them. The Xbox Series X will have Microsoft’s Project xCloud, which will essentially turn your Xbox into a server that you’ll be able to access from pretty much any device and play your games, a little like Playstation Remote. Another new feature of the Xbox will be a Windows Mode, according to some recent leaks. This would allow you to access Steam and the Epic Games Store and play PC games directly from there. As Mouse & Keyboard are fully supported, the Xbox Series X will be closer to a PC than a console. Also, Microsoft has already confirmed that all the Series X “Exclusives” will also work on PC, so the Series X won’t have any console exclusives games. That’s pretty much it in terms of the Xbox. Microsoft hasn’t really talked about any other new and exclusive features. On the PS5 side however, we do get quite a few unique features.

We can already get 3D Audio on the PS4, how much better will it be on the PS5?

For one, Sony has teased 3D Audio quite a lot. They said that this will make a massive difference as to how games are perceived and that the PS5 will even have a hardware based 3D Audio Chip that will handle all the 3D Audio processing. Now, there are a few First-Party headphones from Sony, which do support 3D audio on the PS4 already and we happen to own a pair. They’re very good, but from the looks of it, this 3D Audio chip should take audio to the next level. Something else that Sony will have is next-gen haptics on the controller itself. Sony has already confirmed that the haptics in the new controller will be so good, that you will be able to feel the surface that a car in a game is driving on. So you will be able to feel the difference between asphalt, dirt, grass and so on. And lastly, the PS5 will support both the current PSVR as well as the upcoming PSVR 2. Microsoft has already confirmed that they won’t be doing a VR headset for the Xbox Series X anytime soon, as Phil Spencer himself, the head of Xbox, said - “nobody’s asking for VR”.

One last key thing to mention here is that both the PS5 and the Xbox Series X will support Backwards Compatibility in games. The PS5 supporting PS4 games with rumors of this going all of the way back to the PS1. While the Xbox Series X will support Xbox One games as well as Xbox 360 games.

Conclusion

In the end, both consoles are going to be light years ahead of even the PS4 Pro and the Xbox One X so no matter which one you get, you’ll be extremely happy. The Xbox will offer slightly better specs and PC game compatibility, while the PS5 will offer things such as Haptic Rumble on the controller and VR support. Also, Microsoft will be offering two models of the Xbox, a low-end and a high-end, while Sony will only offer one, the PS5.

Phil Spencer might think the console war with Sony is over, but who’s he kidding?

Which one are you getting?
