And? Who cares. I debated the points presented.
You are missing my point however.. .That flops is essentially useless unless you understand it's purpose... And 99% of forum respondents don't. It's a buzzword.
| freebs2 said: It's not a random number since the Switch 2 is supposedly based on Ampere architecture and Ampere GPUs are modular. |
Even before the "GPU" existed, video cards tended to be highly scalable in terms of functional units.
| freebs2 said: That said I wouldn't trust too much rumors atm as it seems they are based more guesswork based on similar known architectures. TBH 1.536 cores seem like a lot for essentially a mobile device based with an 8nm chip, I would say that would be absolutely the upper limit. |
I disagree. 1536 is very low-end in this day and age... nVidia doesn't even make an RTX GPU with that amount of functional units.
I think there will be a hit to clockrates, no doubt. Mobile always does.
| freebs2 said: I remember there was some talk around a patent for Supplemental Computing Devices (SCD) sometime ago. But in hindsight it doesn't make too much practical sense on paper since it would mean creating and maintaining different production lines for 2 different chips (one for the console and one for the dock), designing and producing two different heating dispersion systems, and they would need to find a suitable connector for ensuring sufficient data bandwidth between the two processors. In the end if the use case is the new next gen console, it would be a more effective solution to simply design and produce a more expensive chip on the console (for example using a single chip based on 5nm node rather than using 2 chips based on 8nm). Even if the use case is simply extending the lifecycle of the current Switch 1 for TV users, it would make more sense to simply release TV-only version of the console that integrates both the CPU and a larger GPU on a single larger chip rather than connecting the Switch to a power dock with a smaller GPU chip. |
You might as well sell us two consoles. A fixed home console and a portable based on the same hardware.
I think Nintendos approach with scalable clockrates is the best approach honestly.
| Slownenberg said: I'm not technical on this stuff but in old threads from years ago commenting on that idea people who seemed to be more technical would always say it wouldn't be possible I guess because the connection between the Switch and the dock isn't fast enough to allow such a thing. |
Correct... The current Switch piggybacks off USB which isn't fast enough or low-latency enough to handle the data required to be transmitted between both devices.
But if a Switch 2 doesn't use the USB protocol and uses something like... PCI-Express, then it would become technically possible.
But I think the general consensus today is that multi-GPU approaches are a waste of time and effort... It doesn't scale linearly and it increases developer burden and thus the likelihood of erratic performance and bugs. (This coming from someone who used to run with 4x Radeon in crossfire at one point.)
| Captain_Yuri said: I think it's unlikely to happen because it will add too much cost with not much gain unless they really want to jack the price up. USB4 is certainly fast enough to support external GPUs but having portable device that has it's own GPU + another GPU in the dock within a $400 price point is asking too much imo. And idk if people are willing to pay $450-$500. I think one reasonable way they could pull it off is to ship the base dock without any GPU and such but with HDMI and etc similar to the Switch but they can sell docks with more powerful GPUs separately. But I don't think Nintendo is the type of company to go that hard into hardware and assuming the Switch 2 has DLSS, it can do wonders even upscaling from low resolutions to 4k. |
USB 4 Gen 3x1, Gen 2x2, Gen 2x1 is the same bandwidth as USB 3's variants. That is... 1.2 to 2.4GB/s. Just different encoding.
USB 4 Gen 3x2 doubles things to 4.8GB/s. Which is still not fast enough.
Keep in mind it's got to transmit more than just display or audio data.
USB can take 125ms or more for a transaction.
30fps needs 32.2ms. 16.7ms for 60fps. - Starting to see an issue?
| eva01beserk said: I doubt it. The most likely thing I see hapening is they have active cooling on the dock. That way they can overclock it a lot more in dock mode. That might actually be good as i think the switch even docked dosent get to the highest clock the tegra can reach. |
Nowhere near it infact.
The Switch tops out at 768Mhz... And people have taken the Switch and overclocked it to 921Mhz. And it can definitely scale above even that as Maxwell Tegra will happily run at 1.26Ghz when allowed.
