Nvidia RTX Discussion

That was good price lucky people that got it a man I'm so unlucky dam well maybe 5070/ti be a little easier to buy I hope but probably not.

I would have had to go for a psychiatric evaluation afterwards but I was prepared to buy a 5090 FE if I'd somehow managed to win the refresh lottery and get an order in. I'd no interest in anything else so didn't try to buy the any of the 5080s I might have had a shot at.

There's a Scan page about the 50 series which won't encourage you about pre-orders including gems like: "Due to Chinese New Year we do not expect significant replenishment stock for a few weeks." I'd hate to put my money down for months on a pre-order but given nobody will be taking them for FE cards and I'm not dropping €3200+ on the cheapest other dual slot 5090 my sanity is saved there ;)

And UFF, earlier Scan's cheapest price for a 5090 was the £1939 of the FE, now the cheapest is £2100 with and ETA (like all the pre-orders) of 2-12 weeks!

AMD have even said that the launch delay helps them get even more stock in place and in the pipeline AND of course they are only talking about one chip for now which should have made it easier for them to line up supply lines. Question is if this encourages them to try and keep the launch price higher given they'll effectively have no competition for people who just want to buy a card without being scalped or pressing refresh a few thousand times.

I've a feeling nvidia have been very pleasantly surprised at the yields for the GB202 (5090) and if that's the case I wouldn't be holding out any hope for a 5070Ti breaking the trend as it's just a cut down 5080 with the 5090M between which could take up most dies before they have to cut them down to 5070Ti levels.

What I wonder is where the good GB202 dies are now because I don't think there's anything public about what will happen to them! I wouldn't be surprised if some AI slush fund driven lunacy has dropped a not low 9 figure sum to take them all for the foreseeable :-O

The first 5090 has popped up on adverts at a measly 4K 😂

So glad I pulled the trigger on the 4080 Super back in September. Would not have been worth the wait for the 50 series.

Its just depressing

For the first time since the 1080 era I'm skipping this gen across the board, excepting any failures/replacements. My 4090 is still ticking along nicely and even with the trickle down upgrades in my house I'm not going to invest near 3K for a 25-30% boost. And tbh the 5090 pulling at or peaking over the rated max for an already problematic power cable is a recipe for disaster.

With what seems to me like a very good breakdown of the underlying reason quickly following it from BuildZoid which explains why the 3090Ti was ok but the 4090 and 5090 are built not to avoid problems and it's not the connector itself, though it's brutally low safety margin plays it's part in the disastrous results.

My guess is if DerBauer had been willing to open the cards up he'd have found wonky/severed connections from the 6 pins of the connector to what I'll call the bus bar that carries the current to the card, though it's also possible a cable is faulty and I was disappointed he didn't check the resistance on each pin across both cables to examine that. So I'm guessing it's probably a manufacturing defect but the card design and stupendously low safety margin of the connector means the cards are begging for it to happen.

It'll be fascinating to see if nvidia even attempt to try to justify the design which just effectively treats the 6 pins as 6 strands of a single cable. That wouldn't be a problem if each strand could carry 600W but when the connector can only tolerate 110W per pin it's mindbogglingly facepalming penny-pinching on $1600/$2000+ cards as just a single wonky strand/pin throws the rest out of spec under load!

tldw; if you absolutely must have a 5090 it's probably only Asus on their stupid Astral cards who have actually done anything to avoid the potential problem and even then it might depend upon you responding to a software warning rather than the card disabling itself before it starts melting or even a fire. The rest of the cards just bridge the 6 12V pins so the cards have no idea if the 600W is coming balanced across the 6 pins or if it's all coming on one pin.

Id have actually bought a 5080 at or close to msrp, got a 7900xtx from Amazon instead for 920, if the 9070xt is revealed, worth it (ie similar performance to the xtx), and priced right I'll return the xtx for it. Would definitely prefer the 5080 for RT, dlss4 and cuda/tensor workloads but they can't be got, and I'm not sure they where ever designed to be sold at msrp

Every step of the 5000 launch has been a disaster tbh, pricing is barely a suggestion, availability is non existent, performance is negligibly better, the new power connector is still catching fire.......... and yet the cards are selling out instantly 🤷‍♂️ madness

Maybe they thought they could make only 5 5080s considering how long the original 4080s sat on the shelves 🤷‍♂️🤣
