NVIDIA RTX 50 SERIES - Technical/General Discussion

Not good guys, rtx5090 full load and the GPU side connector is hitting 90c and the PSU side connector is hitting 120+ degrees

Rtx5090 cards should have two power connectors; one is not enough headroom and it is playing with fire, literally

Horrendous. I thought some other articles were click bait, but if he's concerned. Not sure if he suggested Asus had something different to ensure the the amps were more evenly spread between the wires?

Truthfully, the only game that has made me go “meh I’d really like to upgrade now” is Silent Hill 2. But even looking at @mrk ’s 4090 FPS with this game I haven’t thought “wow that 4090 is light years better!” - it IS a lot better but has seemed a shade on the ‘underperforming’ side relative to where I’d like to be when I do upgrade, which is running at 90ish fps with bells and whistles on. Lo and behold, the 5090’s uplift will get me where I want to be. Great.

Keep in mind before the last big patch to Silent Hill 2,m framerates were lower, they fixed the CPU utilisation issues and frametimes which resulted in higher fps - My initial fps numbers were before these fixes. I had completed the game long before then so only casually went back after the patch and haven't replayed since.

Thsi is the issue, it's not GPU related, it's purely down to game optimisation and people should not be basing a buying decision based on fps numbers alone for games that are running engines infamous for poor optimisation until the devs actually do some work to fix it.

Since they have only made 100 units of the 5090 worldwide, there's still time for them to recall it. You really have to wonder how incompetent Nvidia's hardware design and testing is if they saw this issue with the 4090 and then decided to pump an extra 150W through the connector.

Nobody (sane) is buying second hand Strix 4090 for £2,300

IMO nobody (sane) would have bought it new at that price when it was brand new

but you can't buy any high end GPUs at sane levels atm so todays buyers are forced into waiting (with no end date in sight), compromise or getting rolled

Might turn out to be a good thing waiting a couple of months for a 5090 to let issues a hopefully fixes come through for potential coil whine to cable overheating?

Yeah absolutely ridiculous how hot they are getting, these cards should have been fitted with 2 of these connectors rather than stuffing 600w through a single connector

As for the Astral yes it has the ability to monitor amp draw though each of the pins using Asus GPU Tweak 3 .

It presents a situation that has never happened though. It's comparing things that haven't existed at the same time.
As for cards under msrp all last year and until last week you could get a 7900xtx for well under 1000. And they've only just sold through now as people have looked at the price of the 5080 and noped out of that.

Hopefully in a few weeks the 9070 cards will appear with better price to performance. But who knows.

I do think it feels like it's either falling for the marketing or being disingenuous to look at what for now is a best case scenario for the 5080 and compare it to what we know to have been almost worst case for several cards on that list. 7900s were all well under msrp for the majority of thier life, 4080 supers were often seen for 900 - 950. And those are all a generation older than the 5080, and its embarrassing that the 5080 isn't clearly better value.

Yes, the chart I posted does show things from a specific view which can you fairly argue never existed.

The same applies in all circumstances though and it works both ways; the only cards available at a given time are the cards that were available at that time… so where other cards were unavailable, there will obviously be no dynamic effect across the pricing stack. It also means you can’t go back in time and say “but this was priced at this at a previous time when these other cards weren’t available”.

Here are two other charts that are interesting, posting for a fuller picture regardless of whether they support any viewpoint. You can find the complete set here.

Cards at their prices as they are available today:

Ah, thanks. Ordered the 5090 TUF, so might be the same. I need to go and look at my 4090 Strix now in GPU Tweak III, to see if thats an option....

Cable was hitting 150C after 5 mins of stress testing and this is on his own 5090 Founders edition card, PSU and PSU cable.

As far as I can tell it’s really not that bad on the price / performance front:

In fact, going by that chart there isn’t a single card that can actually outperform the 5080 whilst offering better performance / price.

By that logic if the 5080 launched with an MSRP of $50 it would be the best GPU Nvidia ever launched, even if it was a totally made up price because no one ever bought one for that price.

The page you took that image from says this...

Manufacturer's Suggested Retail Price, or "MSRP" is what the GPU vendor says their product should cost. Since street prices are different, especially for older cards, we've been using actual-market-pricing in our reviews. Comparing MSRPs across generations could still result in interesting insights, especially for historic considerations, which is why we're including these charts. Please note that comparison cards are listed with the MSRP price points that they originally launched at. For your purchase decisions you should always consider current market pricing, like we do throughout this review.

So they're well aware of the limitations of such a chart.

Would be interesting to see the same PSU and cable temps when stressing a 4090. See if they are the same

Yes. I refer you to my subsequent posts pointing out that no recent launches have had ‘good’ AIB cards available for MSRP one week into their launch.

I had a 5090 preordered, saw a review saying that at full load it took 632w through the connector and I was like "nope. not in a million years"
Even if the connector itself is now "safe" they are pumping way too much power through those units. it is an accident waiting to happen.

People may hate on the 5080, but I am happy with my purchase. and even if the 5090 was only a little bit more money I am not sure I would want it.

I remember when the 5000 series was launched, 1usmus did a post saying if he had presented that wiring diagram to his university professor back in the day, he would have been kicked out of university, he said these cards would burn up

also:

NVIDIA GeForce RTX 4090 and 5090 prototypes featured quad 16-pin power

Can't argue with that. If... I did buy a 5090, i'd be power limiting that bad boy straight away. 10% margin of error for the connector is utterly stupid.

 

[Ascendancy]

My 5090FE is undervolted and only draws ~450w so it might be alright. I'm going to stick a temperature probe near my PSU connectors tonight and see what the readout is.

 

[Monkeyboysteve]

Apparently its a great overclocker, any idea how much headroom there is on a 5090? Probably not too much, I'd imagine.

Considering how much wattage is already going through many 5090s (the one I preordered had 632w at full load, obv more that the 600w the cable is rated for) I wouldn't want to risk overclocking one tbh...
My 5080 is currently 400Mhz on gpu clock and 1000Mhz on memory. that's without touching voltage, not a single crash and no coil whine.

 

[john_smith]

Without undervolting, is this issue fixable? I can't see it.

It's only a option on the Matrix with the 40 series, I'm not sure if they have included on the TUF or PRIME with 50 series but is 100% available on the Astral both 80 and 90 .

Yes, cant see it. Not a worry at present with the 4090. Thanks.
