I dunno if a next gen console can get 1.8ghz clocks with more than 40 CU's, but i also expect that a cut down 5700 is too weak for next gen & Sony/Microsoft are aware it's in truth a budget mid range GPU that is for some reason $450, they will likely want something with more punch, but who knows.
Likely the 1.8ghz leak isn't PS5 & that PS5 uses something with at least 48 CU's.
According to hmqgg Arden and Argalus are not even Anaconda and Lockheart. Rather something else:
But then he says:
Which is confusing because hmqgg is the first person to mention Arden and Argalus. Brad Sams even credits him in his videos.
Brad Sams only mentioned Anaconda, Lockheart, Maverick (XB SAD) and Anubis (Scarlett SoC).
As far as I can tell Arden and Argalus came from hmqgg.

Do we have any clue what that can be? Kits for xcloud maybe? Or something Surface related?
Reminds me that brad sams reported that specifically xcloud has tf number above stadia's 10.7tf, so maybe they needed a rdna 2.0 chip based off the navi 20 to reach that on the server.
Dont expect a navi 20 derivative chip on a console everyone.
Arden has a non transparent bridge this is cloud related...
Well if those are meant to be servers, then it makes sense to find them on Desktop linux commits. But those APUs are not for home consoles.
New wild theory: all those Navi lite APUs could be aimed for cloud gaming, hence the gaming reference in the serials.
I think you're wrong on this.
Have you looked inside a PS4 Pro, an X1X, a recent high-end graphics card of any sort? In all of these things, the GDDR chips are directly connected with thermal pads to the very same heatsink as the APU (GPU in the case of a graphics card, obv.). They absolutely do make use of active cooling and contribute to the thermal load needing to be handled by the unit's cooling system.
Scarlett Xcloud will be using the same SOC as the console.
Does seem to be for consoles with that clock and naming scheme.. Things are becoming interesting
No idea.
Navi 20, Navi 10 their all desktop parts derivative of Navi and RDNA. Console chips will be custom.
Apparently, so has Gonzalo afaicr.
People want their favorite plastic box to have more flops and special sauce
You miss a point. Teraflops is not relevant.
According to rumors and what we have in terms of intellectual property informations (not talking about raytracing rendering tech here), Sony seams to have build a console arround a very fast SSD (we talk about an SSD capable of theorically 10~20GB/s and no hardware controller) and very fast memory at low power (HBM2 or maybe 3).
This SSD itself is a big achievment if these bandwitdh are turning to be true. A low power memory architecture + a low power SSD tech (no controller avoid heat) allow you to uptempo the GPU.
It seams also Sony using Chiplet architecture contrary to Microsoft.
Welp, there's the secret sauce, game over Playstation won, Reiner was right.
So just another Tuesday lol.
Seems like the new navi 10 post by komachi further points at HBCC and the HBM + DDR4 rumor.
And this just the calm before the storm of the big leaks. We are not ready for when jason clicks publish lol.
This is what I hope for PS5 and XB2 personally
" A CPU that's 32-bit & 733 MHz, custom Intel Pentium III Coppermine-based processor. Has a 133 MHz 64-bit GTL+ front-side bus (FSB) with a 1.06 GB/s bandwidth. The system has 64 MB unified DDR SDRAM, with a 6.4 GB/s bandwidth, of which 1.06 GB/s is used by the CPU and 5.34 GB/s shared by the rest of the system. "

If you think about it, If Reiner got some dev talking, than Jason 100% got some info too
Holy shit that nuclear option would end this thread and crash ERA for hours, most of us would get banned during the all out argument while the remaining survivors will tell stories about how Jason destroyed the internet, and not just ERA, half the internet would implode.
Can't wait for it lol, i'll light a fire and have some fine wine while I watch the chaos from afar.
If I can say, the playstation fan seem the less interested of the two to win the specs war.
I wonder if that's just cause of Vega cards in dev kits,they all have HBM2 memory after all...
Anyway,the only thing that seems solid for several months now: Navi 10 Lite-Ariel is GPU part of Gonzalo and Gonzalo is classified by AMD as gaming device/console,not some desktop part.
Personally as long as both systems are a true generational leap and are priced reasonably then it doesn't matter what one is more powerful, especially if the difference is minimal.
Ddr4, not gddr4
And its more beneficial in terms of cost, power consumption and efficiency
So what's the downside?
Doubtful?
Lower bandwidth overall and the amount of high bandwidth memory is smaller (8gb). This solution is coming from the assumption that developers wont need more than 8gb of fast memory and they can use the ddr4 or the ssd for everything else.
It was debunked by some dev here that gddr6 power consumption is not as bad.
Can you point to this "debunk"? Because most of the posts here do seem to suggest that hbm and ddr4 will use less tdp than gddr6
I was referring to the Gonzalo leak as a whole, sorry for the misunderstanding
https://www.resetera.com/threads/ne...-anaconda-dont-want-none.112607/post-21043234 but not sure is anexanhume dev ;) Edit: maybe it will use less tdp but also will have less bandwidth
So we're missing out on actual rumours from a trustworthy source because people needed to be console warrior asshats. Great :/ And we're still arguing about power based on tea leaves-read intentions from Sony and PR from MS because people scared off the messenger.
I guess I'll skip reading this thread then until news pop-up that are worthy of a standalone thread.

We have a measure coming from TomHardware mesurement it is 16 watts for 8 Gb of GDDR6, 32 watts for 15 GB and 48 Gb for 24 GDDR6* but power consumption is linked to bus size and for a 384 bit I imagine between 48 to 58 watts and all of this without memory controller. It seems they are counting inside GPU power consumption from the tomhardware article...
It seems 8 Gb of HBM2 is 10 Watts and 16 Gb of DDR4 is nearly 7/8 watts, you have a non negligible gain for the same memory size. And HBM3 and DDR5 consume less...
* seems power consumption grows linearly with memory quantity seeing DDR4 measurement

Ok but 8gb for gpu seems small for nexgen and reading from ddr4 is too slow for gpu so you get less power consumption for inferior resolution, nothing breathtakingWe have a mesure coming fromTom Hardware mesurement it is 16 watts for 8 Gb of GDDR6, 32 watts for 15 GB and 48 Gb for 24 GDDR6* but power consumption is linked to bus size and for a 382 bit I imagine between 48 to 58 watts and all of this without memory controller.

About the HBM2 + DDR4 solution, I think the fact that we're dealing with a split memory pool will be a bigger issue than the HMB2 portion having slightly lower bandwidth than GDDR6. Sure there are supposedly some shenanigans going on to make the two memory pools look like one pool of memory and t the memory is supposed to be automatically allocated but what if a developer decides to use 12 GB or more of the 24 GB as VRAM? The Next-Gen Xbox would be at a rather big advantage in that case and that scenario doesn't sound all that unrealistic especially when we look at how the unified memory was used this gen.
EDIT:
I mean this would still be my preferred solution. Would make next gen more interesting and the tdp gains could be invested in higher clocks but there are some significant downsides.

Yeah. It looks like gddr6 is a pretty safe solution for devs

Memory chip power consumption also deoends on the speed of the chips (i.e. memory clocks) and thus voltages.
8GB is enough depending of the speed of the SSD. My bet is 10 GB/s like the example in the patent maybe it will be less... You don't need more than 8 Gb depending of the speed of streaming...
Correct. So clocking GPU core and the memory interface.
It all depends on economics and whether the savings is worth the engineering effort.
As Rylen points out below, it's about balancing clock speed with CU count. The RX 570 uses 75W less than RX 590 with just 4 less CU and a couple hundred MHz lower clocks.
I believe the decoder has no entry for the cache part of the string, so it is unknown.
HBCC is beneficial regardless of RAM setup. Also I agree with others that the remaining two are likely Lockhart and Anaconda.
Previous console APUs leaked out in a similar manner. Read the DF story on Gonzalo.
The dev would be perfectly able to use that much as VRAM if they liked, and from what I gather, not only would the DDR4 be just fine for certain GPU tasks that don't need high bandwidth, but the crazy-fast SSD would make needing more than 8GB of HBM2 very unlikely since you'd need to engage in so much less buffering.
I don't know if this was posted but its good one :D
Here this is for 14 Gb GDDR6... 8 gb of HBM2 it comes from an other article 20 watts max for 16 Gb of HBM2. 16 Gb of DDR4 3200 I suppose are not consuming much more than DDR4 2800 and all the 16 Gb DDR4 seems under 7 watts. I took probably the worst case for DDR4.
