Ponovno odličen članek, tokrat kar se tiče samega nastanka, komponent, AMD sodelovanja,... Inside PlayStation 4 Pro: How Sony made the first 4K games console

Navedek

But perhaps the biggest takeaway I had from the meeting with Mark Cerny was the insight into how Sony views the console generations. PS4 Pro and Project Scorpio have been seen as the beginning of the end of the jump to a new, more capable wave of hardware in favour of intermediate upgrades. What's clear is that Sony isn't buying into this. Cerny cites incompatibility problems, even moving between x86 CPU and AMD GPU architectures. I came away with the impression that PS5 will be a clean break, an actual generational leap as we know it. I do not feel the same about Project Scorpio, where all the indications are that Microsoft attempts to build its own Steam-like library around the Xbox brand, with games moving with you from one console to the next - and eventually, maybe even to the PC.

 

But in the here and now, my meeting with Mark Cerny served two purposes. On the one hand, I saw more of the PlayStation Meeting demos and more of the 1080p enhancements we can expect. On both counts, I'm still impressed by the results of this £350/$399 box. Not every title will be absolutely pristine, but we're seeing good results already and it's great to see developers investigating their own techniques for achieving presentable 4K - I'm really looking forward to seeing how Spider-Man stacks up in particular. And there will be boosts for VR games too, with hardware multi-res support that should improve performance on second-gen PSVR titles.

Infamous na PS4 sem preigral po dolgem in počez. Jo bom pa verjetno ponovno na hitro pogledal. Verjetno me bo ponovno potegnil Uncharted 4 in pa verjetno tudi The Last of Us.
Predvsem me pa zanima kakšne nadgradnje bodo deležne PS VR igre ob igranju.

 

 

Ali je pravi čas za nakup 4K TVja za PS4 Pro?

PS4 Pro review od Digital Foundry:

 

 

PS4 Pro izboljšave napram PS4:

Navedek
  • Graphical and performance improvements to supported games when played on Pro, including PSVR titles
  • 4K resolutions 2160p YUV420 and 2160p RGB
  • 4K upscaling of games with checkerboard rendering, some native 4K games
  • 4K video support (such as Netflix, YouTube)
  • New 'three-tiered' design with larger dimensions (295×55×327mm) and a finish similar to the PS Slim, moving the light strip to front of the device
  • Updated DualShock 4 controller with light strip visible on touch pad and USB data transfer
  • Third USB 3.1 port on rear of device
  • 1TB hard drive space as standard
  • Support for SATA-III hard drives
  • Wifi Improvements - 5GB IEEE 802.11 a/b/g/n/ac supported (though also available with new Slim model)
  • Streaming improvements - Remote Play up to 1080p on PC, Mac and Xperia, Share Play from PS4 Pro at 1080p
  • Share improvements - 4K screenshots, 1080p video, 1080p60 YouTube streaming

Kaj ostaja enako:

Navedek
  • Same library of games - so no PS4 Pro exclusives - with each piece of software a unified package that runs on both consoles
  • PS4 games with no specific PS4 Pro mode set to run the exact same
  • Identical peripheral support, from the DualShock 4 to the PS Camera
  • No PS4 Pro-exclusive features or DLC in any games. However, leaks have said certain modes can be enhanced; one example is if there is a two-player local split-screen mode, it could expand to four-players on Pro
  • Shared and equal PSN ecosystem, so regular PS4 users can play and interact alongside Pro users with no differences online, and vice versa
  • Save data, Trophy and PSN account log-in compatibility between the two systems, with the same user interface
  • PlayStation Store will be the same, but expect pages and physical game-packaging to list PS4 Pro-added features
  • HDR visual support, also available to base PS4 systems through firmware update 4.0

Kaj Pro ne ponuja:

Navedek

UHD Blu-ray drive support for 4K movies on disc (due to the popularity of video streaming, according to Sony)

 

Pri obstoječih (ne izboljšanih oz. ne Pro patchanih) PS4 igrah ni performance (FPS) razlike:

Navedek

we decided to begin our tests by looking at the presentation and performance of existing PS4 titles. Rather famously, Xbox One S features a GPU overclock compared to the standard model, resulting in a small bump to performance that while not essential, is clearly nice to have. When I spoke to Mark Cerny about improved base PS4 performance on Pro, he ruled it out completely pretty quickly and this is borne out by final hardware.

Pcars_Base_vs_Pro_000.bmp.jpg

Razlog tiči v tem, da se število Pro GPU jeder v "PS4 mode" prepolovi (iz 36 na 18) in hkrati tudi zniža frekvenca delovanja jeder (iz 911MHz na 800MHz). 18 GPU jeder s frekvenco 800MHz je enako kot jih ima originalni PS4.

Zakaj takšna poteza Sonya? S tem je Sony omogočil 100% kompatibilnost Pro modela z originalnim PS4. Tu velja omeniti, da je MS v Xbox One S vseeno pohitril GPU frekvenco, kar se vidi v nekaj opaznih frameratih več v določenih igrah.

 

Kar se tiče Pro podprtih iger, so med njimi velike razlike in je trenutno precejšnja zmeda. Niti niso posebej označene, da bi takoj vedel katere imajo Pro podporo. :(

Velja tudi omeniti, da Pro podrte igre predstavljajo največjo razliko ob 4K TV uporabi, vendar(!) tudi na 1080p zaslonih je razlika nezanemarljiva! Največ iger koristi tako imenovan super-sampling. Pomeni da se igra zrenderira v resoluciji višji od 1080p, nato se pa naredi downscale slike na 1080p. Prednost je, da je precej manj kockastih linij (aliasing).

 

HDR je sicer super, da je podprt, vendar kolikor berem je tehnologija še preveč v začetni fazi. Težava se pojavi, da TVji nižjih in srednjih rangov niti približno ne prikažejo HDR zmogljivosti in zadeva zaživi šele na TVjih višjega ranga. Mislim da je pametno počakati z nakupom 4K TVja do prihajajočega CESa, ki bo takoj po novem letu.

 

Poraba elektrike:

Navedek

Base mode also throws up some interesting metrics based on power consumption - despite shutting down half of the GPU, the PS4 Pro uses more power to run base PS4 code than the new CUH-2000 PS4 'Slim'. It's still significantly more power efficient than a CUH-1000 launch model though, and the overall power consumption figures for the Pro are fascinating. The Pro's new processor is fabricated using FinFET transistor technology, so performance per watt is a big improvement compared to the original PS4.

Generally speaking, playing a fully enabled Pro title only takes around 10W more power from the wall than running a standard PS4 game on launch hardware (this will vary on a title by title basis - we used InFamous First Light as our test subject here), which explains why the rated power consumption has increased to 310W and why we have reverted to the 'kettle' power cord used on the launch PlayStation 3. It should be stressed that the 310W metric is almost certainly the rated capacity of the internal power supply - actual consumption is around half of that during standard gameplay on Pro-enabled titles.

 

Hrup:

Navedek

In terms of the acoustic performance of the Pro, it has much more in common with the c-chassis PS4 than the Slim. We were hoping that the larger console may integrate a larger fan - typically, the larger fan, the slower it needs to spin in order to displace the same amount of heat. We've yet to put the Pro through exhaustive tests here, but we note a peak 55dB during inFamous First Light gameplay, but really it's not so much the loudness that's the issue as opposed to the pitch. The fan spins up and down and is clearly audible from across the room. Initial tests on heat again show a profile similar to the standard PS4. We'll have more on this to share later, but right now, it's fair to say that a fair amount of heat is kicked out of the rear of the unit and in common with any current-gen console, it should not be housed in an enclosed area.

Torej kar se tiča hrupa je bolj podoben CUH-1200 modelu, kot Slimu, kar je škoda. V vsakem primeru je dobro, da je tišji kot originalni PS4.

 

Pro sicer nima vgrajenega UHD Blu-Raya, vendar Netflix app že deluje tudi v UHD resoluciji. Kar je zanimivo je to, da media player ne zna predvajati 4k videje. Isto težavo ima tudi XO S. Verjetno se obema obeta naknadna programska posodobitev, ki bo omogočila 4k predvajanje v vgrajenem media predvajalniku.

 

Kar se tiče PS VR izboljšav:

Navedek

...demos we've seen to date show that super-sampling is used to reduce aliasing and improve clarity in the HMD. The Pro also features multi-resolution scaling technology not found in the base PS4, which should help performance.

Torej trenutni naslovi so deležni predvsem večje jasnosti. V modoče se obetajo grafično precej bogatejše igre oz. izboljšana gladkost delovanja. :thumbsup:

 

Digital Foundry zaključek:

Navedek

Has PlayStation 4 Pro managed to live up to its marketing? By and large, yes. At its best, it is capable of producing compelling results at native 4K. Stack up Rise of the Tomb Raider on Pro against an ultra high-end PC and run them side-by-side and you'll see that most of the 4K clarity is there, much of the detail is there and frame-rate remains the clearest differentiating factor. But the fact that a £350/$399 box is capable of even competing is a remarkable achievement.

 

It's clear that the key technologies are in place to ensure that PS4 Pro can work very nicely in the 4K world, but launch software shows that the transition isn't going to be entirely smooth. Many titles are operating at resolutions much closer to 1440p - a pixel-count we'd previously established as a better fit for the core hardware based on established rendering techniques. The fact that Uncharted 4 doesn't reach 4K or even 1800p isn't a great turn-out bearing in mind how the Pro is marketed and the title's status as the flagship PlayStation 4 technology showcase. The thing is though, that it still looks really nice - modern rendering techniques are making the seemingly definitive link between pixel count and image quality much more of a grey area.

 

We expect Pro implementations to improve over time, and the first party Sony titles we've seen in the pipeline (Horizon Zero Dawn, Days Gone) looks simply sensational, but it may be some time before developers fully get to grips with the new hardware. But on the flipside, even in the here and now, even with so many different high resolution mode variations in the titles we've looked at so far, the bottom line is clear. Not much more money is buying a whole lot more power.

 

If you don't already own a PlayStation console and you're looking to invest, the Pro is a no-brainer. You're getting over twice the GPU power, a faster CPU, future-proofed display and streaming media support - and twice the hard drive space. The price-point is keen enough that it's going to take some seriously aggressive bundling deals to make the standard PlayStation 4 look appealing.

 

But if you already own a PS4, the choice of whether to upgrade is a tricky one. There are no system exclusives, the library is the same, and existing games will only run better if developers go back and patch them. If you own a 4K screen or are considering a purchase, the upgrade will be highly worthwhile, but what's clear is that there's little here likely to make your existing console obsolete. With an installed base rapidly approaching 50m users, that's probably a very good thing. But with that said, if you read Digital Foundry, if you appreciate image quality and performance as we do, it's really difficult to overlook the fact that there's a system out there that's better than what you have now - and if more titles follow the approach to enhancement seen in the likes of Rise of the Tomb Raider, PlayStation 4 Pro becomes an essential purchase.
