The big grain of salt with that "the 5070 performs like a 4090" is that it is talking about having the card fake in 3 extra frames for each one it properly generates. In terms of actual performance boost a 5070 is about 10% faster than a 4070.

Source for your 10% number?

I heard them say that in the Hardware Unboxed youtube video yesterday.

I think it's this one https://youtu.be/olfgrLqtXEo

Because if two frames are fake and only one frame is based off of real movements, then you've actually lost a fair bit of latency and will have noticably laggier controls. Making better looking individual frames and benchmarks for worse gameplay experiences is an old tradition for these GPU makers.

If anyone thinks they are having laggier controls or losing latency off of single frames I have a bridge to sell them. A game running at 60 fps averages around ~16 ms and good human reaction times don’t go much below 200ms. Users who “notice” individual frames are usually noticing when a single frame is lagging for the length of several frames at the average rate. They aren’t noticing anything within the span of an a…

I'll take that bridge off your hands.

Similar CUDA core counts for most SKUs compared to last gen (except in the 5090 vs. 4090 comparison). Similar clock speeds compared to the 40-series. The 5090 just has way more CUDA cores and uses proportionally more power compared to the 4090, when going by CUDA core comparisons and clock speed alone. All of the "massive gains" were comparing DLSS and other optimization strategies to standard hardware rendering. Som…

I started thinking today, when Nvidia seemingly keeps just magically increasing performance every two years, that they eventually have to "intel" themselves, where they haven't made any real architectural improvements in ~10 years and just suddenly power and thermals don't scale anymore and you have six generations of turds that all perform essentially the same, right?

Nvidia is a very innovative company. They reinvent solutions to problems while others are trying to match their old solutions. As long as they can keep doing that, they will keep improving performance. They are not solely reliant on process node shrinks for performance uplifts like Intel was.

The increasing TDP trend is going crazy for the top-tier consumer cards: 3090 - 350W 3090 Ti - 450W 4090 - 450W 5090 - 575W 3x3090 (1050W) is less than 2x5090 (1150W), plus you get 72GB of VRAM instead of 64GB, if you can find a motherboard that supports 3 massive cards or good enough risers (apparently near impossible?).

Sooo much heat .... I'm running a 3080 and playing anything demanding warms my room noticeably.

I wish mining was still a thing, it was awesome to have free heating in the cold winter.

Is it not? (Serious question)

Probably not on GPUs - think it all moved to ASICs years ago.

So you are saying that Nvidia will finally force USA to the 220V standard? :)

Many American homes already have 240V sockets (eg: NEMA 14-30) for running clothes dryers, car chargers, etc. These can provide over 7200W continuous power! I guess PC power supplies need to start adopting this standard.

You can't use a NEMA 14-30 to power a PC because 14-30 outlets are split-phase (that's why they have 4 prongs - 2 hot legs, shared neutral, shared ground). To my knowledge, the closest you'll get to split-phase in computing is connecting the redundant PSU in a server to a separate phase or a DC distribution system connected to a multi-phase rectifier, but those are both relegated to the datacenter.

You could get an electrician to install a different outlet like a NEMA 6-20 (I actually know someone who did this) or a European outlet, but it's not as simple as installing more appliance circuits, and you'll be paying extra for power cables either way.

If you have a spare 14-30 and don't want to pay an electrician, you could DIY a single-phase 240v circuit with another center tap transformer, though I wouldn't be brave enough to even attempt this, much less connect a $2k GPU to it.

GPUs are in demand. So scalpers want to make a buck on that. All there is to it. Whenever demand surpasses supply, someone will try to make money off that difference. Unfortunately for consumers, that means scalpers use bots to clean out retail stores, and then flip them to consumers.

Without thinking about it too deeply I'm wondering if GPU demand is that much higher than let's say iPhone demand. I don't think I've ever heard of iPhones being scarce and rare and out of stock.

Apple very tightly controls their whole value chain. It's their whole thing. Nvidia "dgaf" they are raking in more cash than ever and they are busy trying to figure out what's at the end of the semi-rainbow. (Apparently it's a B2C AI box gimmick.)

DLSS 4 uses a completely new model with twice as many parameters and seems to be a big improvement.

I hope so, because it looks like 8k traditional rendering won’t be an option for this decade.

there aren't many 8k monitors. I would rather have 300fps 4k

This years founders edition is what I really want from a GPU. Stop wasting my 2nd PCIe slot because you've made it 3.5/4 slots BIG! It is insane that they are now cooling 575W with two slots in height.

I would suggest getting a case that has a set of inbuilt (typically vertically-oriented) expansion card slots positioned a distance away from the regular expansion card slots, mount your graphics card there, and connect it to the motherboard with a PCI-E riser cable. It's what I did and I kicked myself for not doing it years prior. I have no experience with PCI-E 5 cables, but I've a PCI-E 4 riser cable from Athena P…

Can you link to an example case and riser cable?
