Digital Foundry PS4 Pro Launch Coverage Begins

You can only checkerboard up to a certain resolution by already rendering at half of that resolution. So, 1920x2160 can be checkerboarded to 3840x2160, or 1600x1800 to 3200x1800.



Problem is that people are not understanding what checkerboard is.
1800p checkerboard is not 1800p native upscaled to 2160p.
It is a an equivalent resolution of 1800*1600 rendered pixels on an alternated checkerboard pattern that is used to reconstruct a 1800p image (1800*3200) which then gets upscaled to 2160p (2160*3840).
At the same time 2160p checkerboard is an equivalent resolution of 2160*1920 pixels that is used to fully reconstruct a final image of 2160*3840 pixels that do not requires further upscaling.

Thanks for the explanation , I thought it works like the bolded part. i will keep this info in mind for the future :)
 
Sony should clarify their FAQ.




and add "but it won't make it any faster... problem?" trollface.jpg

To be fair, OP should add Richard was speculating based on the lower than even SATA II speeds on the PS4, it didn't sound like he's definitively saying they tested the PS4 Pro to be that slow.

If the limit was the ARM IO chip, I wonder if they beefed that up for instance.
 
I tried to tell people it wasn't upscaling from the beginning but so many was stuck in their ways yelling that it was upscaling & it caused a long lasting effect on people who was on the outside looking in because they thought the crowd yelling "it's upscaling!" was right, that plus Richard having a bad habit of calling it upscaling has caused a lot of damage.

They probably call it upscaling because it is still a method to end up with more pixels than what you actually render but it creates confusion because people are used to think about upscaling as a technique that starts from a full resolution picture as a basis and here it's not the case.
Checkerboard should be called a reconstruction technique rather than an upscaling technique to avoid confusion.
 
Also, one of the previous videos noted Richard lost an extended family member recently, didn't it?

Maybe a little more understanding here...He probably had a stressful time there, and then it's like

"Unboxings are inane"
"Richard, go unbox that thing on video"
"...Fuck".

Exactly, that's a big difference because pixels are still mapped 1:1, you are not "spreading" fewer pixels to a higher resolution
 
The bolded is incorrect, I think you may have meant many current devices do not have the required Hdmi chip for the requirement of RGB(4:4:4) around 18Gps. The 2.0 spec does indeed support that and some devices on the market including forthcoming sets and Moniters Do have the required chips.

This is always the confusion (mostly intention) of new standards as all rush to shift units while the standards are all settled and in place.
Which displays currently support this? The HDMI spec shouldn't allow that so it would surprise me.

http://www.hdmi.org/manufacturer/hdmi_2_0/hdmi_2_0_faq.aspx

According to every chart I've viewed/spec sheet I've read, including the official HDMI specs, this is the current situation. 18gbps gets you 10 or 12-bit color with 4:2:0 chroma subsampling. 10-bit RGB requires greater than 18gbps.

I have tested a LOT of displays including the Sony ZD9 and various LG OLED TVs (I own a B6 myself) and this chart is 100% consistent with my findings. Not one of these was able to output 10 or 12-bit color using RGB due to this limitation. If you wanted to use the higher bit depth, you were forced down to 4:2:0. RGB is only available in 8-bit color in HDMI 2.0.

Why would that have anything to do with the arm chip?

It's thought the PS4 custom southbridge has all IO routed through it and contains the ARM trustzone processor. As a low performance processor it's perhaps the reason why PS4s hard drive throughput is below where we'd expect even from SATA II.

Beyond that it's thought that the ARM chip was so underpowered, rest mode doesn't work as well as they expected and they need to keep the APU partially on even for downloads.

Remembering that, I wonder if the Pro fixes that too.
 
Oh man, a GTAV update would be splendid.

Yep! but I think it's too big of a game to be 4K only on one console so if it does happen it will be when Scorpio comes out so it can be 4K on both consoles & not boosting sells for just the PS4 Pro.

Even performance boosts would be awesome.
 
Update 3:
Per Cerny, the new GPU is doubling the standard PS4 GPU. Backward compatibility is accomplished by essentially turning off half of the compute units. They talk about Xbox One S and how the higher clock CPU gave some games a small framerate bump. Leadbetter says he's pretty sure there won't be a difference here with PS4 Pro because it's something Sony was very adamant about.

No reason for me to get a Pro then.
 
I hope the generational tension between these two men continue in future videos.

Haha, glad I'm not the only one who noticed that Richard was being way too hard on that poor guy lol. Ordering him around near the start, and then flat out interrupting him and being blunt later on. Felt so bad for Tom lol...
 
Any news on Doom and World of Final Fantasy getting some type of patch? I just bought them both (Doom was on offer)
 
This is my 4k set, it does 4k 60fps/4:4:4 with HDR.


1080p @ 60Hz Show Help : 32.1 ms

1080p With Interpolation Show Help : 48.8 ms

1080p @ 60Hz Outside Game Mode Show Help : 48.8 ms

1080p @ 60Hz @ 4:4:4 Show Help : 32.1 ms

4k @ 60Hz Show Help : 51.0 ms

4k @ 60Hz @ 4:4:4 Show Help : 51.0 ms

4k @ 60Hz + HDR Show Help : 53.5 ms

4k @ 60Hz @ 4:4:4 + HDR Show Help : 53.5 ms
 
A Hisense H8C, I presume? You probably got that from RTINGS, I'm guessing.

Here's the thing, that column listing 4k @ 60Hz @ 4:4:4 + HDR does not actually state 10 or 12-bit color.

I know for a fact you can send HDR to a TV in 4K60 4:4:4/RGB but it won't actually be 10-bit. I've done this before and the results are pretty reasonable but you will see additional color banding in many areas of the image. Shadow Warrior 2 on the PC is a good test for this as you can use HDR in 8, 10 or 12-bits per channel but in 8-bit there is additional color banding.

Every single piece of material out there indicates that HDMI 2.0 does not support 10 or 12-bits per channel at 4:4:4 4K60. Display Port has the bandwidth for this but doesn't yet support HDR metadata nor is it available on any consumer 4K TV that I'm aware of.

So RTINGS also scores the LG B6 OLED TV, which is what I own, and includes...

4k @ 60Hz @ 4:4:4 + HDR - 38.2 ms

Yet I know for certain that the display does not not do this in 10 or 12-bit color. It will do 4:4:4 + HDR in 8-bit color but that isn't really useful.

I've tested a number of other TVs on that list as well which RTINGS also scores in that column. Not one of them supports 10 or 12-bit 4:4:4.

I do suspect some of these displays ultimately have the muscle to pull this off but are limited by the HDMI standard itself. HDMI 2.0 is the problem.
 
Yes, a small performance boost without a patch would eventually made me buy it.

I really don't care for 4K gaming so it's pointless to waste +400 dollars on this now.


So small performance boost to some games that have unlocked frame rates is worth $400 but the benefits that the patched games & all future games are getting isn't worth $400?
 
No reason for me to get a Pro then.
That's odd. While it's true that other non-Pro games won't necessarily benefit, pretty much everything going forward will support this new system.

What XB1 S did is great. Performance boost without a patch.
Barely and only in very select games.

What the Pro offers is significant different and better.
 
I hope it won't be until 2020 that we can have such TVs. :p
This was my thinking constantly, I held off buying a 4K TV because there are going to be updated sets next year. But this is tech, every year something new comes out and every year we're told to wait. So fuck it, went and ordered a new TV :p
 
I don't care for performance boost that needs a patch.

After this year most games won't need a patch anyway since it will be build in .

You are saying that having 3 to 5 fps jump on certain games on X1S was worth it .
While pro going to have much more than that on some old games and all the new ones not worth it .
 
I don't care for performance boost that needs a patch.

I think the PS4 Pro may not be for you unfortunately. if I understand the performance boosts were not intentional and not even really patches but a side effect of the CPU high clock rate.

Per DF:

Xbox One S has a GPU clock-speed of 914MHz, up from 853MHz in the older unit. That's a 7.1 per cent increase...

Could be something they (Sony) implements down the line? But 7.1% increase is not enough for me to outweigh the overall benefits in visual and resolution benefits. I'm not a graphics specialist but am planning to purchase a 4K TV and only play on PlayStation devices so it fits my needs perfectly.

Maybe wait for Scorpio?
 
That's not actually a DF piece, I should note.

Apologies and Touche. Are DF and Eurogamer not one in the same or connected in some way?

Edit: I see. I will be more specific next time. Digital Foundry = In-depth technical analysis of games and gaming hardware at Eurogamer.net.
