>But Cerny seemed more excited about another one of these “post-Polaris” features that the PS4 Pro has: a significant improvement in the way it handles 16-bit variables like half-floats.

>With the PS4 Pro, said Cerny, “it's possible to perform two 16-bit operations at the same time, instead of one 32-bit operation. In other words, with full floats, PS4 Pro has 4.2 teraflops of computational power. With half floats, it now has double that -- which is to say, 8.4 teraflops of computational power. As I'm sure you understand, this has the potential to radically increase the performance of games.”

Explain this sorcery /g/.

there's nothing special here. if you legitimately think the ps4 pro is an 8.4 tflop machine comparable to a gtx 1080 you should really jump off a bridge to certain death.
>>
>>57211023
I think the better thing to ask is what can a 16bit float do and what do you need 32bit or 64bit for?

I don't know what is actually required for a videogame, but its usually referred to as precision, and Im not sure how much precision is required for a game.
>>
>>57211694
consider 2 bits that can hold 4 different values, nothing more, nothing less. Now go make a 3D game where everything is bound to be in one of 4*4*4 places, with literally no way to have anything be in between. Good luck.
FP16 is no different, it literally has a sqrt of possible values of regular float
>>
>>57211833
fp32 =~ 7 decimal digits precision
fp16 =~ 3 digits precision

it's enough for storing things like a subpixel color value or a lower precision normal vector.
expect a lot of postprocessing work to get shoved into fp16-heavy shaders.

Why does everyone think you can just use half precision without any downsides at all.

The point is that the option is there. You can choose to use full precision, or half precision. You keep full capability of full precision for graphics engines that actually have a use for it, but can choose to use half precision for retro 2-D games that are poorly optimized and/or have pointless physics features and ai features.

because it's a relatively new feature
I'm not sure if you can run single precision and half precision code in the same shader which is limiting it's uses to post processing shaders. even fragment shaders need normal and vertex calculations which could degrade quality significantly if ran in half precision

I think Pascal can because Nvidia was talking about mixed precision compute some time ago

Clickbait article title. Vectorized half float operations is fine, but the use of a 16-bit float has such a limited range where the minimum strictly positive (subnormal) value is 2^-24 ≈ 5.96 × 10−8, the minimum positive normal value is 2^-14 ≈ 6.10 × 10−5 and the maximum representable value is (2-2^-10) × 215 = 65504. Slap on a negative sign and that's not a whole lot of precision or range of values you can express with that.

The only thing I can see it used a lot for is low resolution 2D images/textures which can fit within that range. And I doubt that it would boost game performance anywhere above 5%.

I think this mid-generation stop gap nonsense is going to turn out in Microsoft's favour, because they had the right approach from the very beginning in using Win 10 + DX12 and the UWP. It will make transition to new hardware so much smoother, which is something PC gamers have known for 20 years.

The PS4 was clearly intended as a single platform for a generation, and now Sony have realised it's not going to cut it for VR and 4K. So they've kind of cobbled together this PS4 Pro and it just sounds like kind of a mess. Adding an extra 1GB of slow DDR3, unable to radically change the CPU or GPU architecture without breaking compatibility. It may work, but it doesn't sound like a very elegant solution at all and I think they've reached a dead end now.

I hope you know what this means, less precise floats = less quality and more inaccuracy.

No. Anybody who uses a single metric to judge performance of CPU/GPU is a idiot. There is numerous factor that effects performance.

The ddr3 will most likely be system reserved, so the speed of it won't matter. People should read the extra ram as extra gigabyte of gddr5 for games instead a gig of ddr3 for the os, that's what's important.

The ps4 pro is a midrange mainstream pc with the rx 480. The scorpio should be equivalent to a higher end pc since its basically all but confirmed to be using a cut down 490 vega 10 chip. The scorpio is the new xbox 360 and I'm glad about that since we'll get good high quality ports to pc now since devs will have to work on scorpio ports at 4k.

>>57218910
It doesn't even have an rx480, it's a bit below an rx470

I'm pretty sure it's got a full polaris 480 chip that's underclocked to shit tier levels of performance.
>>
>>57218874
Not sure how the PS4's memory controller works, but my suspicion is that it's being used as swap space and they've probably added it in the cheapest way possible, via PCI-express or whatever the PS4 equivalent is, because adding another separate memory controller for just 1GB of slow RAM would be a waste.

>The scorpio should be equivalent to a higher end pc since its basically all but confirmed to be using a cut down 490 vega 10 chip.

The Scorpio is confirmed to be using HBM?
Color me skeptical.
The Vega 11/RX 580 with 8GB/1kb wide HBM2 won't be released until next Spring or Summer, and there's no way Hynix and Samsung have made enough modules for a mass console release yet.

There will be no such things as generations anymore. The companies will just keep selling us upgraded consoles every 3 years which will be able to play all the original games from the original consoles. All xbox one games run within an emulator anyway so I guess they're thinking for the future and potential hardware changes which could break games. Directx will make xbox ports between consoles piss easy too.

Let's take away from the bullshit for a moment and ask the better question

Loading Linux/windows on a ps4 pro. How comparable is it to a standard mid to mid-high pc considering its price

I have it preordered and will be loading Linux regardless due to 4.XX kernel exploit being present and just need to know where it stands as a budget "pc".

Yes I'm this autistic and will genuinely use it as a pc replacement once I have a reliable way to load windows/Linux
>>
>>57219524

>>57219570
It won't load windows, no console ever has done.
It has an 8 core CPU with a low clock speed (i think ~2GHz) based on AMD's mobile jaguar architecture. It's going to have terrible performance if it does actually run Linux.

I've been able to at least play some native Linux games on steam like portal and portal 2. Managed to get Arma 3 going (at least into the tutorial but crash once done)

I assume that the system will run slightly better with his hardware but im also fucking retarded and have no idea. I'm a software ended person not hardware.

it really wouldn't. 4k30 is way, way easier to run that 4k60 especially as these consoles are using medium settings 90% of the time. i can max out every recent title at 4k on my old 980 i bought 2.5 years ago and get a locked 30 fps. even in witcher 3 with hbao on and everything set to ultra.

AMD cards aren't uniformly beefier, most just the shader arrays.
They love compute shading everything and postprocessing, but they've skimped for the last several years on the fixed function units like ROPs, tessellation, and geometry shading.

Vega will almost certainly be 2x Polaris 10 using HBM2 instead of GDDR5, including having only 64 ROPs and 288 TMUs, etc.

>>
>>57221444
>>57221585
Due to the way they cluster things, it will actually probably be 256 TMUs (compared to 160 in 1080 and 224 in TXp) and 64 ROPs (64 in 1080, 96 in TXp) but it could also be 96 if they wanted to add another block per CU.

But being 2.3x (+/- 0.2) of a RX 480 in a 230W thermal envelope is actually not that bad a spot to be in, which is closer to the Titan X than to the 1080.

In the end though, Vega will live or die based on how many pieces of shaders they can get ported to fp16.

Vega will presumable fix Fiji's horrendous bottlenecks caused by trying to squeeze 4k shaders on a 600 mm^2 die, by doubling the per-ALU L2, geometry, and rasterizer capacities.

ok, for shits and giggles here's hawaii as well.
you can really see by comparison that fiji stripped out a lot to get all their shaders in.
>>
>>57224787
Fiji doesn't have anything "stripped out."
How are you this fucking retarded? Per CU Fiji has more transistors than prior designs like Hawaii and Tahiti.

Why are you even posting here when you're this painfully clueless and uneducated?
>>
>>57224830
It's the balance of Rasterizers, Geometry Processors, and (to a lesser extent) ROPs to CUs within a Shader Engine:

> Hawaii: 1R - 1GP - 2ROB - 11CU
> Fiji: 1R - 1GP - 16ROB - 16CU
> Polaris: 1R - 1GP - 8ROP - 9CU

Fiji would probably have fared better in gaming with 6 SEs with 12 ROPs and 9-10 CUs each, but AMD probably wanted to be able to angle it effectively towards the HPC market as well.
>>

There are plenty of things that could mean ML, maximum likelihood is what came to mind first.
>>
>>57225004
You demonstrably don't know what any of these terms mean.
The Geometry processor, the command processor is front end. It is not part of the CU. ROPs are the back end, and they are not directly part of the CU either.

The only area that Fiji is lacking is pixel throughput, and this is the result of AMD reducing complexity of the back metal layers. The interconnect between CU and ROP is complex and has an enormous impact on how a die yields. Complicating critical layers in an already huge die is suicide unless its selling price can justify low yields.
The other issue is the architecture of AMD's ROPs themselves and the number of pixels/clock they can push.
Fiji had nothing "stripped out" and it most definitely has nothing to do with its caches.

You literally have no idea what you're saying at all. 100% tech illiterate retard.

>>57225055
Where in the previous text did I claim anything was part of a Compute Unit?
I was merely talking about the balance of different pieces, including CUs, within larger Shader Engine blocks.

Don't be so eager to be a douche that you don't read others' comments carefully.
>>
>>57225055
>The only area that Fiji is lacking is pixel throughput
But that's demonstrably wrong. Fiji still gets killed in TWIMTBP games with high tessellation due to:
- lower tessellation and transform capacity
- 16 pixel raster blocks vs. 8 px blocks in recent Nvidia designs
RBE/ROP capacity may be too low depending on who you ask and what kind of shaders are being run, but that's a secondary concern.
A lot of other people repeat rumors about GCN's internal L2 cache bandwidth being lacking, but I've not actually seen that proven one way or the other.
>>

Just what we need right? Not any of that innovative game engine and physics stuff, more blurry AA and chromatic aberration.
>>
>>57225055
Oh shit it's this guy again.

All he does is act superior on /v/ in his spare time and calls everyone else "tech illiterate retards". Nice to see him get schooled here though.
>>
>>57225335
Tessellation is a non factor, anything over 8X gives horrid diminishing returns, and it can be manually set in your driver control panel. The front end has never had a practical impact in anything but review benchmarks run at unrealistic default settings.
Pixel throughput is the only area the designs are lacking, and its the same story with Polaris for the exact same reason. The P10/Ellesmere die with 32ROPs is limited otherwise it would be out performing the R9 390X.

The L2 clock can be tweaked, and doesn't have a significant impact. What it comes down to is strictly pixel throughput. Fiji performs only slightly ahead of Hawaii in some metrics because of this. Computerbase.de showed it in great detail.

>>57226772
I never post on /v/.
Sounds like you're butthurt about being a tech illiterate retard, which by the way is used as commonly as any other insult hurled here.

>>57211833
that is probably the worst possible explanation.

FP16 is good for stuff where FP32 is overkill, rather background stuff or stuff you can't see, physics, AI, etc.

There's enough of those in game engines for it to make a difference.
Right tool for the job.

Why is this needed?

Sony is being retarded. The smart thing would have been to start rumors about the PS5's development and then tease it several months after the scopio's launch. Developing a PS5 would have been dirt cheap, just ask AMD for a Zen and Polaris based SoC. It would dance circles around the PS4 and Scorpio. Both are crippled with a terrible CPU. More GPU power is useless when you have a shitty tablet-tier CPU forming a bottleneck.4K consoles and VR is a giant meme. Consoles can't give us 1080p at 60fps, and now they suddenly want to jump to 4K? What a giant joke.
>>
>>57229554
It's a terrible CPU because they need to stick to a power and thermal budget.

Sort of. It's more like AMD had nothing else at the time besides Bulldozer descendants, which were well suited for neither low power nor gaming applications, so they just added a ton of mobile-tier cores.
>>
>>57230999
Regardless, Jaguar cores are tiny compared to Bulldozer and even more so Zen cores, so they're much easier to include in an APU than huge Zen cores.
>>
>>57231034
They're not exactly massive.

A Zen core is only ~65% bigger than a single GCN CU (5mm^2 w/ L2 vs. 3mm^2 on 14nm).
>>
>>57231116
What's the comparison between a CPU core and a bunch of dumb SIMD ALUs?
>>
>>57231183
The point is that a PS4 has 18 CUs vs. 8 Jaguar cores, and so even if a Zen core were twice the area per equal performance (its not), they still wouldn't be blowing their entire die budget on CPU cores.
>>
Question, I'm aware that most of this shit isn't anything amazing or new. However, will the PS4 be able to run games at a locked 60fps with native 1080p rendering and at least the same visual quality as current games? That is all I ask of it.

Didn't laptops do this between Nvidia chips and on board Intel chips in the 2000s?

They invented a poor man's version of SIMD. SIMD uses a specific register that should be 128 bits in modern systems if I'm not mistaken.
>>
>>57231618
SIMD can be whatever width you want you retard.
GCN uses CUs with 4, 16-wide (i.e., 512b) units.

Furthermore, modern GPUs like GCN and Fermi through Pascal actually use SIMT, meaning that the identical operations are executed on SIMD elements representing data from different threads.

Because threads can have divergent execution flow, SIMT is a lot more complicated to run efficiently than explicit same-thread SIMD.

I would wager it's based on Vulkan, I doubt they're going to create a new API from scratch specifically for Nintendo.
And of course Nintendo are part of the Vulkan consortium.
