Blackwell GPU die sizes revealed; regression in some cases

[Daven]

Videocardz has compiled some great data about the die sizes and transistor density of Blackwell GPUs using HardwareLuxx as the source. It is becoming clear that Blackwell is only about AI/DLSS/RT. So the question is, with the exception of the 5090, will Blackwell have the same or less pure rasterization performance as Ada Lovelace?

Yet some still believe that 5080 will be faster than 4090.

Seems unlikely since the 5080 has an 84 SM count and the 4090 has 144. Everyone might be confused by the DLSS4 only benchmarks provided by Nvidia.

Am I crazy or does this feel like a refresh similar to raptor lake 13k -> 14k, with some extra software as a side main dish. (edit: now that I thought about it... that's the main dish)

Just a bit more juice for all the cards and if your lucky you get some cores on top...

Actually pretty disappointed. But I wasn't in the market for a Nvidia gpu anyway. (expect if they offered a crazy good card PerformanceTo€ wise)

Ohhhh well... let's hope it gets better in the next 4 years... (send help)

How can it have less raster performance?

How can it have less raster performance?

Some of the SKUs have less cores down the stack than the Supers in the 4000 series. Also rumors point to same or less cores in the 5060 series.

Of course you can also have less raster performance if clocks are lowered by more than cores are increased.

Nvidia added a lot more AI/RT/DLSS goodness in hardware. Since the 4 nm node is exactly the same between the 4000 and 5000 series, it looks like Nvidia is being stingy on cores and clocks to compensate.

Expect more of this as process nodes get slower and slower to develop and release to market. Profits must go up and if there is no new node to improve performance/power/area, the die area is going to shrink and shrink.

Yep as many people predicted seems like 5090 is going to be around 30%-35% faster in raster then 4090 but when it comes to the 5080 Vs 4080 situation is even worst most likely only around 15% here the latest benchmark leaks from 2 games where wasn't used frame generation Resident Evil and Horizon Forbidden West

P.S. Note that in Resident Evil Ray Tracing was enabled and in Horizon Forbidden West DLSS was ON....so there is possibility that if RT and DLSS was Off performance increase could be even smaller

Yes, it's a margin expansion exercise pretty much. Only the 5090 looks interesting... It'll probably be a decent card still in 5 years or even 10 given how progress has slowed down. So you can kind of justify the 2k for it in that way.

Pretty depressing times in tech.
