What's up with the funky GDDR6 clocks, do they come from repurposed 'sub-par' 18GBps chips? But then again... where do the good 18GBps go towards? Everything above these 2 seem to be using GDDR6X.

4060 seems to sit between 3060Ti and 3070 and 4060Ti at ~6800XT/3080 based on solely(!) that rumored TSE score. Not bad, not great either (given the hype and the power consumption increase on a bleeding edge node at least)
Also the pretty big gap between rumored 4060Ti and 4070 seems weird. But IDK

There's something funky going on with those 4060 and 4060 Ti specs. Me thinks the TBP is too high, and an upcoming leak will probably bring it down just like it happened for the other SKUs. Either that or Lovelace power consumption shoots up after 2.8 GHz because the perf/W increases with increasing SKU, e.g. 4090 is 3x perf for only 2x power over the 4060? Hm, on second thought maybe not since that tweet says the clocks aren't higher than 2.8 GHz, which is oddly low for that power level. Anyways, something is off here.

Do they really have 7 different chips? That's never happened before.

Also, knowing the performance numbers now about the lower end chips that might take up to a year to release seems a bit suspicious.

Color me skeptical about this.

What 7 chips? Do you mean die or product?
Thats only 5 die & 7 products.

Ok, I see, the two different versions of 104 and 106 are just bins then basically?

There are almost always cut down versions of chips that not meet the full specs. A 4060Ti for instance is most likely a cut down 4070.

I imagine they validate multiple different cuts for every die, and make the decision on what actual cut to use for a given product later.

They've probably already decided. They can calculate the defect rates and such.

Only the 4090 is locked in presumably. All the others could change.

They already know what percentage of AD102's they need to bin down to 4080 Ti if they cut the 4090 a certain way and how much the gap would be to a nearly full AD102 which will go into the 4090 Ti. Then near to a full AD103 goes into the 4080, with a moderate cut for the 4070, where again, they can calculate the percentages that go into each bin.

They also already have estimates of the expected percentages of the market that go for certain tiers.

I think you'd be surprised how close the released products are to the plans they've already made. They don't wing this kind of stuff or will somehow be hugely surprised by what the actual demand will be.

Latest rumors have the 4080 being a 10% AD103 cut and the 4070 being a mostly full AD104. That could change of course.

That would work if the 4080 Ti is a full AD103, rather than an AD102 that was attacked by sharks with lasers.

Most chips, especially for the midrange parts, won't have any defects, but will still be binned and have some hardware fused off to hit clock targets and provide a good product mix.

They couldn't sell all of the full dues they could make at the same price they normally charge, so they just work around the silicon they have to adjust the bins to get the rough percentage mix of the different products. If the market looks like it's shifting they can adjust their production accordingly, even towards the high end as a process matures and silicon quality improves.

OK this is a fun rumor. nVidia might have a 4080 16 GB and 4080 12 GB. The latter being the full AD104 SKU rumored earlier. Which yes would have less shaders than the 3080.

As to why they won't call it the 4070 Ti, perhaps they are concerned about what people think of the 4080 16 GB's price... so making a cheaper model still called 4080 makes everything okay.

So this rumor is saying its going to be like the GTX 1060 3GB vs 6GB all over again? Where the 3GB had fewer shaders than the 6GB?

It would not surprise me if they wanted to say, "Look, we're still offering a xx80 class GPU at the low, low price of $699" until you find out it's the AD104 12 GB, cut down version and the true xx80 AD103 16 GB version is $999.

Was thinking the same. A new low in deception. Desperation setting in?

At this point I just need some Nvidia marketing slides saying how the 4080 12gb is going to be 100%* faster than the 3090 for $699 so I can pick up a top end current gen card for $350.

*In highly specific scenarios involving highly unique settings in a handful of games.

Another day, another rumor. This time, it's about the cooler itself. New font and 3-slots apparently. The fan has a new blade design as well. Take with a grain of salt. The fan looks like it clips through the frame, so could be shopped.

Vs. Ampere for comparison:

Hm, maybe it is legit after all... Basically Ampere cooler but bigger fan, revised fan blades, probably thicker head sink as well.

seems like it'll still be 2-slot card based on leaks, just much bigger fans.
Interesting how "2-slot card with massive cooler" is the niche that FE cards accidentally fell into. ITX builders dream
