you're gonna have to look for illegally obtained information on your ownNice. Can you point me to that data so I can have a look, kind people? I'm not familiar with where to look.
What interested me about the direct was that some of the games were late into 2024.
Luigi's Mansion 2, for example, was summer 2024. A game like that you'd think they'd announce in the Feb direct.
Does it mean anything? Dunno!
This threadmark is informative for a high level overview. Ditto to what LiC and ILikeFeet said.Nice. Can you point me to that data so I can have a look, kind people? I'm not familiar with where to look.
They announced it to try and capitalize on the Mario movie popularity. Probably quite early into production, yeah.That is shocking. By the time it releases, it would have been announced a year before the release.
Especially seeing how it's just a remaster of a 3DS game and Metroid Prime and SMRPG got a much closer announcement to release date and they are full-blown remakes, heck I wouldn't be surprised if TTYDR releases earlier in 2024 than later.
So maybe Luigi Mansion 2R was supposed to be released earlier in 2024 but got delayed or Nintendo decided to just announce it way earlier.
His latest tweet today seems more firm compared to his 2022 tweet when he put a question mark next to it. Maybe there was no new info and he's just repeating what he knew and he didn't bother indicating it was his lack of firmness, but it's just worth noting.Are you not aware that kopite had said T239 would use SEC8N back in June 2021, when he first talked about the chip? It's not new information. The people who have debated and theorized about the node since then were fully aware that he made that claim, and people who expect a different node are just more persuaded by other evidence and also aware that kopite is not very reliable for Tegra information and T239 information specifically. Him saying the same thing again now, with no additional context, and no new details being proven correct since all the things he got wrong, doesn't really warrant this warning from you.
Yeah, if you drill into this, or go to the other threadmarks, there's a post I made detailing how the relationship between Nintendo, NVN/NVN2, and T239 is not in question. In the facile sense of "anything is possible," sure, we don't know that Nintendo hasn't totally cancelled NVN2 and everything associated with it and is planning on releasing an AMD-powered home console instead. But unless they did that, NVN2 and T239 are what is going to be used in the hardware released next year.This threadmark is informative for a high level overview. Ditto to what LiC and ILikeFeet said.
That's definitely not the case.His latest tweet today seems more firm

There are plenty of other examples I could have used, too, I just picked the ones that needed the least context for non-technical people to understand. Another would be, without getting into the weeds about what this is for, this code comment:
"V2's only addition is MIG support [...]; should be identical to V1 for T239 since it can't do MIG."
Something changed from V1 to V2 in the common libraries Nvidia is pulling into NVN here. But they put a note saying it's okay to use the V2 version of it because the only change from V1 is for something that's not relevant to T239. They only call out T239 here, because it's the only chip that is the final target, so everything revolves around its capabilities and behaviors.
That's definitely not the case.
This tweet, which came 13 days after his original post about T239, is very definitive -- and at minimum, it's 50% wrong already, because Orin and Drake are not based on Ada.
This is my worst nightmarea chonky boi, or low battery life in a hot box
yeah i didn't see that 2021 tweet, i was pointing to his tweet last year when he gave himself a scorecard of what he got right (i guess in 2021) at the time he put a questionmark next to the process node, meaning he was unsure or perhaps to indicate it remains to be seen.
I know. But considering he was just as "firm" about several things in 2021 that turned out to be wrong, I don't find convincing the argument that his recent "firm" tweet is an extra-credible claim. The tweet I posted is from about 8 months before Orin developer kits started shipping, so the fact that he was still claiming it was based on Ada suggests that he doesn't have good information on Tegra chips even when they're nearing release.yeah i didn't see that 2021 tweet, i was pointing to his tweet last year when he gave himself a scorecard of what he got right (i guess in 2021) at the time he put a questionmark next to the process node, meaning he was unsure or perhaps to indicate it remains to be seen.
And correct me if I'm wrong, but wouldn't going with 4N also make more economical sense? Yes, 4N is 2.2x more expensive compared to Samsung 8N, but is 2.7x more denser, which means more bang for the buck.The only reason I think the process node is interesting from a Nintendo Switch 2 point of view - when I was holding on hard for the idea of 8nm, I just had to believe in bargain basement clocks. Like, well below peak efficiency, because as we'd discussed before marginal gains are still gains.
Once I really started to think about 4N as possible, then it made the device not just seem more possible, but more sensical. If you've got to clock well below peak efficiency to get your battery life where you want it, why not cut SMs, and clock higher? 8SMs at peak efficiency would offer more performance than 12SMs at bargain basement clocks, while also offering comparable battery life, and being a cheaper chip to make!
4NM seemed like an implausible choice at the time, but it started to make various decisions line up - and once I considered 4NM, I could really think about what the range of clock speeds would be, which is where I switched from thinking of a 6x perf leap (the CUDA core numbers) as a max, to thinking of it as a floor
I still try not to get too hyped up by performance numbers, but it is more fun that way![]()
"Thinking he heard something..." the hell is this?What launch-timing related rumors do we even have aside from Nate thinking he overheard something about March?
"Thinking he heard something..." the hell is this?
The mention of March was repeated numerous time and it wasn't in passing. March was stated, specifically, and a talking point at Gamescom. It came up in all conversations around the successor. The only unknown was to which it was referring -- be it launch, an announcement, a reveal, or a deadline for games to target.
I'm sure that game is pretty much done or close to me finished. I think they're spacing it out so they don't have droughts. I also think there's a decent chance LM2 could be used as an example for RT. Of course, we don't know when Switch 2 will come out.That is shocking. By the time it releases, it would have been announced a year before the release.
Especially seeing how it's just a remaster of a 3DS game and Metroid Prime and SMRPG got a much closer announcement to release date and they are full-blown remakes, heck I wouldn't be surprised if TTYDR releases earlier in 2024 than later.

No an area of uncertainty is how I’m gonna make it to your place, I owe you corn muffins from that final reveal from the direct todayStill an area of uncertainty.

Unfortunate, let's hope TGS clears these grey skies just a bit.Still an area of uncertainty.
This uncertainty got me thinking. Are your sources / or the people your sources talked to just being coy with this date? Usually dates are attached to an event and it's a bit odd to heard a date but not know what it's about.
it's more logical (i would think) to hear about a potential event without a date.
What's your hunch on this? And its ok if you don't feel like spelling iut out, but i just find it odd we have March 2024 but not know what its for.
I think he gave his thoughts on the podcast. March release sounds exciting but it being an announcment date makes far more sense. It also lines up better with his informed speculation I believeWhat's your hunch on this?

Right, the A/B/C are "GPU classes" which basically mean a certain configuration of hardware that has to be controlled a certain way by the driver. For example, the "clc797.h" file contains the register mapping for sending signals to control GPUs in that class and make them do 3D rendering stuff. It has nothing to do with the node.I was looking at the original Kepler_L2 tweet where he referenced this https://github.com/NVIDIA/open-gpu-...f20fa2be4825bd72ee/classes/3d/README.txt#L100, and which kopite responded to with his Samsung 8N claim.
I went through the Github and compared some of the classes. They're denoting different architectures with different 3D graphics/CUDA version capabilities.
Take MAXWELL_A vs. MAXWELL_B. They're both on 28nm (with a big caveat I'll mention later). The difference is that A is Maxwell and B is Maxwell 2.0. Using Techpowerup's GPU database to compare GM107 (Maxwell 1.0) and GM204 (Maxwell 2.0) we find that:
Maxwell 1.0
Maxwell 2.0
- 64KB L1 cache per SMM
- CUDA 5.0
- NVENC 4th Gen
- 48KB L1 per SMM
- CUDA 5.2
- NVENC 5th Gen
The big caveat here is GM20B, which is the GPU found in the Tegra X1 in the Switch. This is also using Maxwell 2.0, however it is tabbed on TSMC 20nm (for the original, Mariko) and not 28nm like the rest of Maxwell 2.0 (and Maxwell 1.0, and Kepler 1.0/2.0).
Essentially, this Github file is separating classes by architecture and their associated 3D/compute capabilities and NOT by node. And of course, we know that GA10F in T239 is using Ampere, but to assume that because it is in the same class as the other desktop Ampere GPUs (AMPERE_B) it is using the same node (Samsung 8N) is entirely illogical.
No Kepler wasn't saying that. Was mostly posting for some additional context about that Github file and for some comments I saw elsewhere (mostly Reddit) concluding that this somehow provides additional support to the 8N claims.Right, the A/B/C are "GPU classes" which basically mean a certain configuration of hardware that has to be controlled a certain way by the driver.

Was Kepler_L2 saying that? I think he thinks it's a big reveal that it's part of Ampere as if we haven't all known that for literal years, and he seems to be making a lot of stupid posts about it. Not sure it was being used as evidence of the node, though.
Exactly. Like, is the vagueness really due to Nintendo literally just saying, "Hey guys, stuff is happening related to Switch 2 in March 2024"? That seems pretty unlikely. Why would Nintendo tell devs a date without saying what it's for?I wonder if the conversation goes like:
"So, what's this March 2024 thing about"
"March 2024"
"That...doesn't answer the question. What is that date for?"
"...... March 2024"
"equivalent to throwing hands up in the air"
"March 2024*
As someone else has pointed out, March 2024's significance could be something like Third Party NDAs relating to switch 2 expiring in March.Exactly. Like, is the vagueness really due to Nintendo literally just saying, "Hey guys, stuff is happening related to Switch 2 in March 2024"? That seems pretty unlikely. Why would Nintendo tell devs a date without saying what it's for?
Maybe it was more like "be sure to have your Switch 2 game builds ready by March 2024"? Which could be interpreted as "ready to show to the public via trailers" or "ready to be submitted for lot check"?
Or is it that devs know what it is, but just don't wanna stick their necks out too far and only feel safe revealing that something is happening in March 2024?
What if the "switch 2" was big and unwieldy at first kind of like how the Gameboy advance was and then it will be a slimmer form factor maybe closer to the OG switch like how the SP was to the advance
when the process node gets a shrink/refresh in the future
That's an interesting theory. And that would imply the Switch 2 being announced March or earlier (cause Nintendo would naturally want to talk about Switch 2 before 3rd parties).As someone else has pointed out, March 2024's significance could be something like Third Party NDAs relating to switch 2 expiring in March.
Feel that Gold Deadline for Launch Window Marketing or the actual Early end of the Launch Window is more probable than Announcement/Reveal."Thinking he heard something..." the hell is this?

I guess those weren't the correct words I was looking for but it definitely was on the bigger side of things comparatively to the GBA spThe GBA was "big and unwieldy"?
Are you sure you aren't confusing it with the DS phat?
The optimist in me says "Switch 2". The pessimist in me says "Xbox Series". Normally you wouldn't expect to see a game like this on Xbox, but Microsoft has shown a greater willingness to chase after anime games in recent times.someone in r/HonkaiStarRail pointed out this asterisk in the PS5 release date trailer for Honkai Star Rail and the comments immediately made me go to this thread

Phil threw money at Persona. He could throw money at this.lol at the people thinking it's for Xbox
Well, an announcement, deadline or a reveal would be about the same no? If it’s going to be announced, things should be ready to showcase it. If it’s a deadline, then that means a reveal would be eminent and things should be wrapping up. Reveal is self explanatory, and things should be wrapped up already for that period."Thinking he heard something..." the hell is this?

That’s true if it were TSMC, Samsung doesn’t have a good track record when it comes to that though lol
It's sort of true, but also not really that relevant to the comparison. Partly because we're comparing between different foundries. TSMC's more mature nodes very likely have better yields than their newer nodes, but there's no particular guarantee that an older Samsung node has better yields than a newer TSMC node. TSMC's 5nm node family (which includes 4N) reportedly achieved very good yields at an early stage, and now has been used in shipping products for over 3 years, so is relatively mature in any case.
Secondly, yields are inversely proportional to die size, and if you are comparing yields of the same chip between the two processes, this is probably going to be the bigger factor. In this case, we're talking about the same chip either way. We know it's got 8 CPU cores, 12 Ampere SMs, and has assorted other coprocessors, interfaces, etc., and these things are going to take up the same number of transistors whether it's on TSMC 4N or Samsung 8N, so it would have to be a much bigger chip on 8N.
For the sake of argument, let's say it's a 10 billion transistor chip, just for a round number. On Samsung 8N, Nvidia was getting a transistor density of around 45.6 million transistors per mm², which would indicate a die size of 219.3mm². On TSMC 4N, Ada chips are coming in at about 121.1 mT/mm², which would give a die size of 82.6mm². The 4N version of the chip is obviously much smaller.
Now let's talk about yields. You may see articles claiming that a process has "70% yields" or "90% yields", which are irrelevant if you don't know the size of the die. A 70% yield on an 800mm² chip would be incredible, whereas a 90% yield on a 20mm² chip would be below-par. The actual measurement of yields* is defect density, which is a measure of how many defects you have per unit of die area. Typically this is measured in defects per cm². This Anandtech article from before TSMC 5nm chips hit the market indicated they were operating at a defect density of about 0.1 per cm², and showed yields had improved more quickly than their previous nodes.
There's a little maths involved to calculate the yield of a chip from a die size and defect density:
Yield = (1 - DefectRate)^DieSize
Where both the defect rate and die size are measured in the same units (in this case we want to convert them to cm²).
Let's assume for a second that both Samsung 8N and TSMC 4N have the same 0.1 per cm² defect rate. Using the die sizes above, and the formula for yield, we get a yield of 79% for 8N and 92% for 4N. That's the difference the die size makes. Even if Samsung had half the defect rate, at 0.05, it would still only manage 89% yields. Realistically, yields have almost certainly improved for TSMC's 5nm class of process in the 3 years since that article, so I wouldn't be surprised if we're at around 95% yields on 4N for T239.
* There's actually also a second, completely separate measurement of yields, called parametric yields. The parametric yields are considered low when chips, although functional, aren't able to hit the required clock speeds, or require too high a voltage to do so. This is quite a different problem, as much to do with chipmakers expectations as to do with the actual process, but clearly wouldn't be a problem for 4N, as it would produce chips capable of much higher clocks at much lower voltages than 8N could.
