Nvidia RTX Discussion

A new era in 3D graphics stands before us.

First-gen Raytracing GPUs:

Nvidia "Turing" - Quadro RTX 5000 / 6000 / 8000 (US$ 2'300 / 6'300 / 10'000)

More Videocardz "confirmations":

Very strange disparsity between 3090 & 3080, if true.

Also you're getting an engineering masterpiece that some could only dream about not so long ago.

Your making me feel like I'm getting great value out of my R9 380 I bought almost 5 years ago

I think we're going to see RT coming into it's own in this generation. Furthermore I think it's something nVidia will do better than AMD and this is where PCs will lead the field.

Also a very good thread here on why Turing actually wasn't as overpriced as everyone claims them to be:

I'm not sure the data says what they claim it says though. You can see Turing is visibly above the best fit for the previous price/performance data. You can make a case for it being in line with Pascal by itself, but it doesn't have the same value jump as the previous steps from Kepler to Maxwell to Pascal.

We still have feck all games that use RT and by the time the market is saturated with games that have it will the 20 series performance be up to par for it?

The performance future depends on the next gen consoles, they will push the PC marked for a change - while I don't believe for a second that PS5 will be equivalent to a 2080ti it definitely be over the current mainstream PC GPU (which is what, the 1060?).

I will get a lot of time from whatever I buy alright. My 1080 has served me brilliantly and I dont regret what I paid for it.

Just galls me givin the lack of competition that Nvidia can get away with pretty much what they want. To me the 20 series was hiked with justification being RT.

People said then it was an early adopter tax but it looks to me it might be a trend,Nvidia could just keep pumping up prices givin lack of competition.

That seems like an awful lot of "data" in aid of justifying buying an over priced GPU to me:pac:

Maybe were stuck with the new price points. For me it will mean just upgrading way less often.

Videocardz just posted that RTX 3080 will have 10Gb VRAM, 3090 a mammoth 24Gb.

Still have my Corsair 860i Plat which never get's pushed hard even under load.

Peak 92% efficiency around 50% load. It's still above 90% in the 25-85% load area. Drops to 85% at 10% load which ain't great but you're using so little power at that point that efficiency doesn't matter much.

Peak load of my PC atm is only around 250-300w. Could easily go up to a 16 core Ryzen and a top end Nvidia card and it still wouldn't be close to pushing this thing hard. This is overkill. 1200w is taking the piss. 1200w's are for SLI machines but who does that anymore?

Cordell

Yes, it may still be 80% efficient across the range, but it most reach peak efficiency 90+% at 50% load. Now, it's definitely not a big deal to waste a few more percents at low loads, but still, it's more waste than a properly loaded PSU.

Not only there is no value in having an oversized PSU, it actually makes it very inefficient to run it under such a low load, so it will waste more power than a properly sized one.

A good PSU will still be efficient at low loads.

What causes wasted power is really the fact we're using ATX-spec PSUs with 3.3V, 5V and 12V rails.
Intel's new ATX12V0 PSUs reduce idle power draw by half.

So the event is 5pm on the 1st?

It will be nice to be able to watch it at a reasonable hour. Hope there's not too much PR bs but the 21 thing makes me feel like the marketing department for Nvidia will be in full flow.

Id really like to hear from AMD soon too. Givin that they may decide a few things after Nvidia drop there new GPUs i wouldnt be expecting anything between now and the 1st but some info before Nvidia can actually release these new cards would be nice.

Homelander

That hardly negates the criticism though? It's not as if the increased wattage has proven its value.

The 850W thing is to account for garbage supplies. You can buy a GT1030 which consumes about 40w of power and on the box it will say "500w PSU recommended" even though your entire machine will use a grand total of about 100w.

"Investing" in a 1200W power supply if you had an FX9590 and triple GTX1080 setup, fair enough. The same power supply for a bog standard 300w machine under load is money flushed down the toilet.

Ha, and people thought I was mad investing in a 1200W PSU. I knew this would happen someday.

Getting ready to upgrade next year and my wallet is scared even thinking about it. €1000 would really want to be the limit I'd spend on a GPU. So hopefully it comes in at £1200-1300 and I'll knock a couple hundred off that in VAT with Amazon Business.

But still, it's crazy money. And the alternative is to have an AMD card. Which is essentially akin to Russian Roulette.

I hear ya bro, I bought a Coolermaster 1000w when I bought my current i5-2500k and people laughed at me big time. Still running perfect and its going to power my new Ryzen 9 rig I just ordered.

Thank God is was modular and even back in the day came with 4x8 pin and 4x6pin connectors for GPUs. Which was unheard off!

Will there be any reasonably imminent knock on effect of these new cards on the 20 series' price do ye think? Building my first proper PC for gaming and the graphics card is the only thing I'm struggling to decide on! Was going to go for a 2060 but might just up the budget to around 500 for a 2070 super, but I'd hang on for a month if there was something better in that price (or a price reduction) on the way...

There should be. I'd hold out for a few weeks and see what happens. Nvidia unveiling some stuff September 1st with releases coming in late Sept/Oct.

Thought that 12 pin was bogus. I guess not.

Recommended PSU is always way higher than it actually needs to be. Good quality PSU's are pretty efficient even when pushed close to it's limits.

If this thing is using Samsungs 8nm process and also using 350-400w then it has to be at least 40-50% faster than Turing unless they put all of the die space/power into RT and DLSS. This 3090 if it's not a titan is a new tier of consumer card as well so I'd expect it to be at least 50% faster than the 2080ti and 4X faster with the RT stuff.

Looks like Nvidias going all out to capture the enthusiast market. AMD won't be beating them on performance in that segment. AMD's top card is only 500mm square. They will compete with the standard 3080 and below. Hopefully better performance at a better price. Nvidia are starting to really take the piss with their pricing.

Cordell

There are quite a few issues with that power figure: the new connector is supposed to be rated for 600W so in this sense the recommendation for a 850W PSU kind of make sense. But on the other end it has 2x 8pin PCIe power connectors which by the spec are rated for 300W combined, so by design this adapter is out of spec, and using it with a PSU that is not able to deliver more power than the spec on the 8pin connectors will be a big problem.
But the PSU requirements are based on the card itself, not some spurious adapter.

Yup,1200W PSU justified because one GPU not even released yet may require up to a 850W PSU:pac:

Cordell

Reading some comments there reveals it's not a new connector, as in it's not proprietary: https://www.digikey.com/product-detail/en/molex/0430251200/WM1788-ND/252501. And this also means we'll see crap adapters and funny pictures of melted wires

Sure, but a raw performance increase at that level or better is to be expected from 3080 over 2080.

If that is true, and if the rumored prices are true, this will be very disappointing.

The major gains are going to be in ray-tracing and DLSS imho.

The performance increase is 20% for the 3090 over the RTX 2080 Ti

If that is true, and if the rumored prices are true, this will be very disappointing.
