Discussion Nvidia Blackwell in Q1-2025

[Win2012R2]

If the 50 series doesn't lose ~5% FPS with transformer vs CNN like the 40 series, maybe the 5080 is at least slightly better.

With transformer quality is improved enough to drop down a level in DLSS res which will give you more FPS than 5%

 

[Win2012R2]

60 series are most probably coming only in 2027.

It will have to be coming in H2 2026 on N3 level process

 

[Win2012R2]

Soooo... say Blackwell in N3P -
1) clock up by how much - 15-20% from current regressed clock?
2) double registers, fix cache bandwidth - how much uplift?
3) 15-20% more cores
4) GDDR7 32-36 Gbits

Should be +50% on 5090 easy?

 

[Heartbreaker]

Not frame gen, just super resolution. Blackwell might handle new and improved model without a performance hit unlike Ada and Ampere. Hopefully we end up with at least a "4080 Ti" rather than just a 4080 Tie.

DF did a quick overhead test for Transformer models.

On Ray Reconstruction. 40 Series actually took a smaller hit than 50 series:
95% performance for 40, vs 93% for 50. 40 series is 2% better.

On Scaling only. 40 Series actually took a negligibly larger hit than 50 series
95.3% performance for 40, vs 96% for 50. 50 series is 0.7% better.

Bottom line, nothing in it. 50 Series really only has more fake frames over 40 series.

Compubase got 12% more at 4K at least.

Compubase got 12% more at 4K at least.

HWUB got 11%... and no better in RT.

HWUB got 11%... and no better in RT.

4% only. I got 1440p because a lot people use DLSSQ(1440p res) from 4k

 

[branch_suggestion]

Actually impressive how scuffed this uArch is.

4% only. I got 1440p because a lot people use DLSSQ(1440p res) from 4k

Might depend on the game choices. Wukong's one example that is no faster on the 5080 compared to the 4080S. Even at 4K it's only 1 fps faster. Fillrate limited perhaps?

 

[SolidQ]

Very powerful GPU!

 

[branch_suggestion]

The silver lining is the memory does help in 4K.
But the BOM hit is less than the perf bump, NV has created a pretty bad generation when GMs are concerned, they will need to sell a lotta 5090s.

 

[Tup3x]

Just node shrink for 4000 series with GDDR7 would have probably been better than this...

 

[Ranulf]

My heart leaps like gazelle and my excitement knows no bounds...for 8% of the time. No wait, with multi frames that is now 48% of the time. Six times the goodness! Six pence the richer in frames!

 

[CakeMonster]

I know these designs are settled on way in advance, but the memory bandwidth increase on the 5090 and 5080 seems to make very little difference if any. I'm not complaining, as its one of the few 'real' improvements, and I'm sure it will help in AI, and over time, but I'm a bit puzzled why they bothered, given how they cheaped out with everything else.

The marketing brochure is out.

From the HUB review comments:

"3070 - 65% of the 3090 performance, 50% of the 3090 specs, 33% of the 3090 price - $500 5080 - 65% of the 5090 performance, 50% of the 5090 specs, 50% of the 5090 price - $1000 This is $670 (33% of the 5090 price) 5070 inside a $1k 5080 box and that's why it isn't even faster than the previous xx90. This is a daytime robbery. This is a scam."


Last of Us thermals/4k comparison:

 

[MrTeal]

Well, reviews are in and shock no one.
Basically an in place replacement for the out of stock 4080 Super at the same price, so we're just waiting on the same generation from 22-26.

Next up, same thing for the 5070 Ti vs 4070 Ti Super and then the clown show of the 5070 being slower than the 4070 Super.

 

[branch_suggestion]

So fmax is straight up lower across the range.
But hey, it will all pay off in 6 years time, trust.

At least the 5080 has some overclocking headroom, probably to allow for a 24GB Super/Ti refresh in the future.

Who is doing the jebaiting?

Jay two weeks ago:

The 5080 is going to be pretty damn good compared to what you got for the same price 4080Super

Jay today:

 

[StinkyPinky]

So 4K mild gains, other resolutions basically nothing. Great release Nvidia.

Now we know why they 'only' charged $1000 instead of $1200 like last time.

 

[Hans Gruber]

Just node shrink for 4000 series with GDDR7 would have probably been better than this...

No node shrink, just a 4080 with GDDR7 would beat the 5080.

 

[StinkyPinky]

I was thinking the same thing. The 4K gains are almost certainly the GDDR7 rather than anything else. So if anything it's almost a regression. What a farce.

Oh Jay. My time of taking you seriously is certainly coming to a middle. Funny though.
