We constructed a 'next-gen' Zen 2/Navi-based PC – how a lot sooner is it than current-gen consoles?

Growth kits are out, recreation makers are briefed. Sony’s PlayStation 5 and Xbox Mission Scarlett initiatives are below means – nonetheless, detailed specs of the consoles are nonetheless a topic of a lot hypothesis. What has been confirmed is that each machines as soon as once more have a lot in widespread: each are produced in live performance with AMD, each use the Zen 2 CPU structure whereas the graphics cores are primarily based on the newest Radeon Navi know-how. The query is: can this ship a full generational leap over PlayStation Four and Xbox One?

I made a decision to get some thought of how these new applied sciences evaluate stacked up in opposition to the current-gen machines – particularly, the improved PS4 Professional and Xbox One X. The work was the premise of a presentation I delivered a few days in the past at EGX 2019, the place Asus Republic of Avid gamers helped out by constructing an AMD-based PC primarily based on my specs. Points of this unit had been then tuned to match the more and more compelling leaks primarily based on the Gonzalo processor below growth by AMD, a chip that’s now virtually sure to be the SoC inside PlayStation 5.

After viewing the Gonzalo leak with some scepticism, I now imagine the proof to be pretty conclusive. A latest Gizmodo report gave PS5 the ‘Prospero’ codename, and though Microsoft refuted a lot of this leak’s recommendations with regards Scarlett, my very own sources have now confirmed the identical Sony codename. Prospero is the lead in Shakespeare’s The Tempest, and Gonzalo is a supporting character. Different leaks have additionally revealed Ariel as a part (the GPU, probably) and once more, that is one other participant in what many imagine to be Shakespeare’s final solo-written play. The Gonzalo leak suggests a 3.2GHz Ryzen CPU, with Sony itself confirming eight cores and 16 threads. The leak additionally suggests a 1.8GHz or 2.0GHz GPU clock. That is remarkably excessive, it needs to be mentioned. Nonetheless, 7nm silicon may be very costly within the right here and now – and getting extra worth from it will contain driving it sooner.

Past that, there are a variety of caveats to place into place earlier than we go on. Whereas primarily based on the Navi structure, we must always count on Sony and Microsoft to have entry to the AMD elements record from the current day into the longer term – in the identical means that PS4 Professional delivered GPU options forward of their debut in Radeon RX Vega. We all know that each next-gen console GPUs characteristic hardware-accelerated ray tracing – which is not current within the present Navi chip. Help for HDMI 2.1 and 8K video output can also be efficient affirmation that the show controller within the new consoles is a {hardware} block that is not current within the present Navi graphics chips.

I might additionally count on to see some in depth customisation efforts from each platform holders – each Sony and Microsoft would have seen the profound advantages of this from their efforts with PS4 Professional and Xbox One X. Additionally noteworthy and price stressing closely: we do not know what number of Navi compute items are in both console, however with the Radeon RX 5700 and 5700 XT offering CU counts that match PS4 Professional and Xbox One X, we will give you some fascinating architectural head-to-heads.

This is the elements record for the Zen 2/Navi PC that Asus ROG put collectively for us:

  • CPU: Ryzen 7 3700X with Wraith Prism cooler
  • GPU: Asus ROG Strix RX 5700XT (RX 5700 additionally used)
  • Motherboard: Asus ROG Strix B450F Gaming
  • Reminiscence: 2x 8GB DDR4 3600MHz
  • Storage: 1TB NVMe SSD
  • Energy Provide: Asus ROG 650W
  • Optical Drive: Pioneer 4K UHD Blu-ray
  • Case: Coolermaster N300

The place we will moderately assured concerning the closeness of our construct is within the CPU structure. Sony has confirmed eight cores and 16 threads, and Zen 2 is in our arms. The Ryzen 3700X is a remarkably good processor, and even on the Gonzalo leak’s 3.2GHz, it effortlessly annihilates the Jaguar know-how discovered within the current-gen consoles. Jaguar was by no means broadly deployed on PC, however AMD did launch it as a low-power, entry-level platform codenamed Kabini. I occur to personal an Athlon X4 5370, probably the most highly effective Jaguar AMD launched within the PC area, and it is a genuinely terrible chip judged by as we speak’s requirements, and it wasn’t near being aggressive when it first launched.

The console platform holders did not have an excessive amount of selection for the CPU part within the current-gen SoCs. Jaguar was the perfect match because it occupied a relatively small quantity of silicon space, and did not devour a lot energy – a very good match for a console field. The answer to its deficiencies was to double up on core depend, with two quad-core Jaguars built-in into the identical SoC. Primarily based on the benchmark right here, I believe it is fairly astonishing simply how a lot recreation makers acquired out of the structure. By my reckoning, a classic 2008 Intel Core 2 Quad Q6600 is probably going as succesful because the model of Jaguar inside PlayStation 4. And as for comparisons with Zen 2? Effectively, we’re in nice form for next-gen.

As an instance, I ran a easy benchmark on each my quad-core Jaguar and Zen 2-based PCs. Cinebench R15 is much from an ideal check, however I selected it as a result of it delivers each single thread and multi-core outcomes and It would not rely a lot on cache or reminiscence bandwidth (facets our PCs that we won’t match with consoles). I benched Jaguar at 1.6GHz to match PS4, and the two.3GHz clock of Xbox One X, successfully giving us the bottom and highest extremes of the structure’s use within the consoles. As it is a quad-core half and the consoles have eight cores, I doubled up the outcome to present an (optimistic) perception into how two of them may match collectively. Zen 2 would not run at 1.6GHz, however 2.3GHz was positive, with a second run primarily based on the mooted 3.2GHz within the Gonzalo leak. I may additionally run this chip natively as each a quad-core and an octo-core half. The outcomes are fairly thrilling:

Cinebench R15 1TCinebench R15 MTOcto-Core Rating
Athlon 5370/1.6GHz35128256 (Projected)
Athlon 5370/2.3GHz49183366 (Projected)
Ryzen 3700X/2.3GHz1106181220
Ryzen 3700X/3.2GHz1528581702

Clock for clock at 2.3GHz, Cinebench delivers a 2.24x enchancment in single-thread erformance, and throughout 4 cores, it is a 3.Four occasions enhance to efficiency in comparison with Jaguar. Issue within the mooted 3.2GHz frequency of Zen 2, and we’re getting a 4.7 occasions enchancment. Bear in mind this is only one workload and restricted one too, one that does not faucet into the brand new architectural options of the Zen 2 core. Stacking up our projected octo-core Jaguar outcomes in opposition to the 3700X with all cores and threads enabled and we retain the 4.7 occasions enchancment to efficiency in opposition to our surrogate Xbox One X rating, rising to six.7 in opposition to our stand-in PlayStation 4. And simply to emphasize once more, that is an imperfect check – a really primary benchmark that simply offers a small trace of the huge improve in efficiency we must always get from the brand new consoles.

It is this big enhance to CPU efficiency that opens the door to the 120fps gaming Microsoft has promised in its Scarlett teaser, however extra to the purpose, there’s big potential for a lot richer, extra detailed recreation world simulations. And we should not neglect the solid-state storage resolution present in each of the next-gen machines. Sure, we’ll get sooner loading, however extra essential is the proximity of an unlimited quantity of knowledge to the CPU and GPU. Video games will evolve in very totally different instructions as a result of even when we evaluate the processor and graphics to the machines of as we speak, I might count on the utilisation of these sources to be very, very totally different.

A generational leap is usually outlined as a 6x to 8x enchancment in efficiency, which makes the graphics aspect of issues probably extra contentious. There may be a lot we do not know concerning the GPU in PS5 or Scarlett – the compute unit depend being a basic factor. So as an alternative, I made a decision to have a look at issues on a extra summary stage. The Gonzalo leak suggests a 1.8GHz or 2.0GHz GPU clock (I opted for the previous), whereas the RX 5700 and 5700 XT ship the identical compute counts as PS4 Professional and Xbox One X. So what if CU depend stays the identical within the subsequent machines, with efficiency bolstered by architectural enhancements and that spectacular leap in frequency?

To get some form of deal with on Navi’s like-for-like enhance in efficiency, we’d like video games: titles that run with unlocked frame-rates and stuck resolutions, multi-platform in nature so we will match them up with the PC variations. After which we have to run these PC variations with the identical visible characteristic set. We settled on two titles. Wolfenstein: The New Colossus on console may be very, very near the PC’s medium settings, and might be configured to run with dynamic decision scaling disabled. In the meantime, Io Interactive helped us out by offering PC-equivalent settings to all console variations of the good Hitman 2. Whereas we will evaluate console to PC, console to console is much less related: Professional runs at 1440p vs Xbox One X’s 2160p in each instances. In the meantime, Hitman 2 will increase facets corresponding to anisotropic filtering and shadow high quality along with the additional pixel depend.

The outcomes are fascinating, nonetheless. Stacking up 40 Xbox One X compute items in opposition to Navi at Gonzalo clocks, Wolfenstein 2 delivers enhancements between 95 to 110 per cent of additional efficiency. In the meantime, two Hitman 2 comparisons present an uptick of 82 to 83 per cent. In the meantime, PS4 Professional vs Navi reveals additional boosts: Hitman 2 delivers 126 per cent extra efficiency, whereas Wolfenstein 2 goes past that, with something as much as a 3.2x enchancment to frame-rates. It is price remembering right here that builders have had points with PS4 Professional when it comes to out there reminiscence, plus an imbalance between compute energy and bandwidth. This may increasingly skew among the outcomes extra in favour of Navi, however with the possible transfer to GDDR6 in PS5, the development needs to be extra profound than that seen shifting on from Xbox One X.

After finishing this train, I’ve a few takeaways. To start with, I believe we’re in secure arms for future console {hardware}: Zen 2 and solid-state storage are real recreation changers, and even when the GPU spec is much less sturdy than RX 5700 or the XT I checked out right here, the means the graphics core might be used will evolve in model new instructions, delivering new experiences. If we’re certainly gifted a GPU able to 2x Xbox One X efficiency, I will be fortunately stunned, however even with extra modest graphics, the probabilities are profoundly thrilling.

Secondly, I believe it is price stressing how the arrival of PS4 Professional and Xbox One X could have skewed our expectations in the direction of next-gen {hardware} – and on the silicon stage at the least, solely a lot can enhance in a few years. PS5 and Scarlett are real successors to a lot older merchandise: the bottom PlayStation Four and Xbox One. In technological phrases, they’re previous, they’re beginning to present their age – besides, we’re nonetheless getting gorgeous experiences like Uncharted 4, Horizon Zero Daybreak, Forza Horizon Four and Gears 5. Sure, PS4 Professional and Xbox One X ship greater decision variations of the identical video games, however they are not the baseline – they’re companion consoles, not the main target for growth. PS5 and Scarlett represent a brand new technology, a brand new baseline and a reset button pressed on the way in which video games are made – whereas on the similar time permitting builders to carry forth experience from the final technology over to the following. I believe we’re in for thrilling occasions.
