NVIDIA to Stick to Monolithic GPU Dies for its GeForce "Blackwell" Generation (2024)

So, if it's an old-fashioned monolithic die, then it's only half what the GB202 they have shown for the datacenter, as that's two dies glued together. So does that mean the 5090 will have a GB203 die?

Looks like the consumers are getting the shaft yet again, unless the 5080 gets the GB203 die as well, I suppose.

The performance uplift over Lovelace will be interesting with this series, as to me it sounds like a lot of overclocking is going to be needed to bring the big performance gains to these cards. Maybe 600w+ 5090s will be a thing, and 350w 5080s etc...?

It's always safe to assume the customer is getting shafted by Nvidia these days.
I used to be so excited for new generation of GPU and CPU but I just can't anymore the pricing is leaving such a bad taste in my mouth I just buy peripherals or add to my water cooling. Honestly consoles never looked better.

If you want the bigger chip pay up for it. This is like saying drivers are getting screwed because you can't pay for a ferrarri.

wolfAll that bothers me is the price, performance, specs, features and power consumption. How the sausage is made is below the waterline to a large extent, unless it's going to significantly impact the above mentioned considerations. For all the hoo haa about RDNA3 being chiplets, it didn't seem to matter all that much, at least not in a positive way for the consumers.

Remember how the Radeon Fury X with HBM wasn't a "big deal", and now look at HBM....it's so valuable it can't be used in consumer cards. The first application or a new technology's isn't always guaranteed to make a big splash, but eventually it catches on to the point where we don't understand how we survived without it. Chiplets WILL happen, it's inevitable.

"These days" or its always been like this? Like Ampere for data center are produced on TSMC 7nm, but retail customers/ gamers' version are produced by Samsung on some matured node. Ultimately, data center solutions are the high margin products and will get the best. So it is not surprising.

An interesting rumor suggests that team red's RDNA 4 generation will see a transition from disaggregated chips to multi-chip modules—packages that contain multiple fully-integrated GPU dies.

Actually, I've read the opposite somewhere - that RDNA 4 will be monolithic, and only RDNA 5 will return to chiplets. We'll see, I guess.

As for Blackwell, I guess Nvidia isn't ready to risk accepting or willing to iron out the shortcomings of the chiplet design (high idle power being the key). Playing it safe makes sense.

pavleGood choice; on-chip communication is still the fastest compared to mosaic structures.

Yes, but the yields are at least x2 times lower than a die half it's size ;)

SOAREVERSORIf you want the bigger chip pay up for it. This is like saying drivers are getting screwed because you can't pay for a ferrarri.

Again comparing video cards with cars :laugh: :laugh: :laugh: :slap::banghead:
Again, you don't change your car every 1 or 2 years just because a new, faster model came in existence. Best comparison you can do, is with the smart phones. However, only suckers buys the exact same phone (let's call it iPhone 14, when the 3 years old model is exactly the same in all possible ways) :))

x4it3nThe real performance increase will probably come from the 512-bit bus w/ GDDR7 since the 4090 is Memory bandwidth starved! (and Blackwell will probably be much better in RT/PT too).
But if the rumors are true Nvidia might go back to 1 Generation of GPUs per year (just like it used to be with GTX GPUs back then).

I will see a 512bit bus when I actually see it, even in a so called $2000+ "gamer card".

pavleGood choice; on-chip communication is still the fastest compared to mosaic structures.

CoWoS is able to provide 8.6TB/s of bandwidth: en.wikichip.org/wiki/tsmc/cowos

That was circa 2022, current implementation on Blackwell could be even better.

On-chip communications have a scaling issue wherein routing more and more data lines throughout the chips becomes increasingly difficult to do in an ideal maner as complexity increases. The university of Toronto did a paper studying the latency of CPUs with and without an interposer which demonstrated that as CPU core count increases so too does the benefit of having an active interposer.

I would say CPU prices are really good, I remember the days when flagship consumer CPUs, such as a X6800 Core2Duo were 1000 bucks, adjusted for inflation that is $1400 dollars. Today flagship prices are basically 700 dollars.

CPU prices are good but yeah I was thinking more motherboard prices being a joke well for X and Z series but B series are not bad at all until you start wanting features like a debug display. Motherboards are very carefully segmented to give very little until you go up in price but they are still cladding them in armour at every opportunity instead of offering better sound , more m 2 or more vrm it blows my mind. And why are decent dual Dimm boards so expensive the current motherboard situation is a joke. I've got no problem putting down money on a board I've spent 600+ on hedt boards in the past but it's got to be value so when I see motherboard manufacturers selling boards at hedt pricing for a lot less and clad in worthless armour instead of quality components yeah it makes me think these companies think I'm a fool but hey at least they got plenty of RGB for me to stare at while I try to work out why they won't boot.

KsushaTeaKisaI'm sorry for off-topic, but when should we expect 5070? Tbh I'm not sure if I should wait for the 5070 or should I buy the 4070Ti Super

next year.

There's no reason for 95% of home users to choose anything other than a $200 B-series motherboard. Prices of Z and X series are artificially inflated to make you think you're getting 2-3x value when you're not.

Why not a Radeon with more VRAM? RX 7900 XT has 20 GB, RX 7800 XT has 16 GB?
I guess right now is a bad moment for buying, because the new generation is coming soon.
