Nvidia 3xxx possible specs.

Having problems installing that new stick of memory? Found some great software or having issues with something? Or maybe want to chat about your PlayStation, X-Box, Nintendo, Sega, even your old Spectrum 48k....! Or maybe something you want to sell or acquire (computing related of course!). Let us know here...

Hi

Nice find! https://videocardz.com/newz/nvidia-gefo ... d-pictured has to be the ugliest GPU I've ever seen! Imagine trying to clean out the dust bunnies on that - plenty to hold onto I suppose as it's so wide!

Hi all

Some great specs and in some ways affordable pricing for the slightly lower spec cards:

https://videocardz.com/newz/nvidia-anno ... d-rtx-3070

In summary:

Code: Select all

VideoCardz.com	RTX 3090	RTX 3080	RTX 3070
GPU		8nm GA102-300	8nm GA102-200	8nm GA104-300
Board		PG132 SKU 30	PG132 SKU 10	PG142 SKU 10
CUDA Cores	10496		8704		5888
Boost Clock	1.70 GHz	1.71 GHz	1.73 GHz
FP32 Perf.	35.7 TFLOPS	29.7 TFLOPS	20.4 TFLOPS
Memory		24GB G6X	10GB G6X	8GB G6
Memory Clock	19.5 Gbps	19 Gbps		TBC
Memory Bus	384-bit		320-bit		256-bit

TGP		350W	 	320W	 	220W
MSRP		$1499	 	$699	 	$499
Now just have to wait and watch the 10x0 and 20x0 Series drop down in price fairly quickly. :-)

Comparing to the RTX2080ti at launch with 4352 cores, 11 GB VRAM @ 1.5 GHz, 13.4 TFLOPS FP32, 250W and $999.

The 3070 looks really good, 50% more FP32 FLOPS from 35% more cores, 10% less power and half the price.
The 3080 looks very good, more than double the FP32 FLOPS from double the cores, and 30% cheaper. The downside is the 30% increase in power.
The 3090 is an amazing performer but I'm not sure it merits the huge price increase over the 3080, 20% better performance for over double the price? I guess you're paying for the RAM.

Looks like either the 3070 or the 3080 for me, 3080 gives 46% better performance for 45% more power and 40% more cost. I suppose it depends on availability and how the prices translate to sterling.

Edit. UK MSRP - RTX3090 = £1,399, REX3080 = £649 and the RTX3070 = £469

Hi all

...and sure enough, I've now seen GTX 1070's for less than £200 and GTX 1080s for less than £300...

I'm "tempted" by the GTX 3070 but the TDP/TGP of 220 W which is higher than the 180 W rating for the 1080...so, a 40 W difference, which is equivalent to 1000 W per day difference - which is about 20p...and over a year, that's about £70 per annum "extra" (in total running costs) for the 3070.

OTOH, a new 3070 will come with a warranty, which a s/h 1080 won't.

Aw....decisions, decisions !!

TDP really depends on the project your running. I don't see my GPUs maxing out on TDP doing BOINC projects. If a 3080 does compute a ton faster than the older GPUs a small difference in TDP doesn't amount to much. Besides, I crank down the voltage/power to my GPUs to save some power. Power Limit in Afterburner is set at 60% on all my Nvidia GPUs.

Hi Tim,

Swap two 1080s for a single 3070, 2/3 the power and 2.5 times the performance :)

.... or run it at 80% power for the same power as a 1080 but double the performance :D

.... or if you want to stay with 1080s, I may have a few going cheap in a couple of weeks :lol:

Hi Carl

Thanks for the kind offer - but as Mark says USA is "off limits" at present due to Covid-19 restrictions.

And by the time I can get over there, the likelihood is that the GTX 4xxx or even 5xxx Series might be out :-(

Hi Carl

Interesting....and way out of my price range :-(

Strange that the website says:
It is also worth noting that the fan of the RTX 3080 Founders Edition is not spinning.
And yet between the 1 and 2 second mark, the video shows that the fan does actually start (and continues) to turn...

Initial reviews are in, mainly games related (big improvement on 4k, pretty similar on 1440 and less as limited by the system) but there are some compute tests:
https://www.computerbase.de/2020-09/gef ... 80-test/4/
  • Roughly 50% faster than a 2080ti running blender.
https://hothardware.com/reviews/nvidia- ... iew?page=2
  • Nearly double the 2080ti performance on SciSoft, ditto for Luxmark.
https://www.tomshardware.com/news/nvidi ... 1600327224
  • Minimal opportunity for overclocking the core (+4%), memory fares slightly better (+8%)
  • Double the mining performance of a 2080ti, could benefit from better drivers, would take less than a year to re-coup the cost. Look out for shortages/price hikes due to miners :(
Also, empty spots on the board for the extra memory on a 3090, anyone handy with a soldering iron? :D And the FE boards come with NVidias new 12 way power connector ... which may only be rated for 25 insert/remove cycles! Don't keep swapping the power cable!

The nvidia-direct cards do look to be better value. The cheapest partner card is over £700.

I haven’t read the reviews in depth to see what they say about thermals mind you. I believe this card is >300w.

And I've just this minute received an email from NVidia saying they were now available :lol:

ASUS and Gigabyte both had cards at £649.98 on Scan and EBuyer.

The RTX 3080 is a 320W card, temperatures seem to stabilise in the mid to high 70s when playing games according to one review I saw.

There MAY be variants with more memory coming - https://videocardz.com/newz/gigabyte-co ... -3080-20gb

I expect they'll be a while yet judging by the demand for the first ones, why produce different cards when you can sell all you make of the original ones?

Some info from PrimeGrid - https://www.primegrid.com/forum_thread.php?id=9294
They claim 2x FP32 performance among other things, which sounds really good for now...
Yes, 2x FP32 since 2x FP32 compute units.
PG softwares use FP32 right?
No, all of them use INT32.
Each Pascal core is a single INT32+FP32 unit. Turing has two separate units: INT32 and FP32. Each RTX-30 Ampere core has two units: INT32+FP32 and FP32. Then RTX-30 can perform 2x FP32 but 1x INT32.
3080 has 8704 'CUDA cores' but that's counting the FP and FP/INT cores separately, really it's 4352 FP and 4352 FP/INT.
For PrimeGrid it's 4352 cores (3080) versus 4352 cores (2080ti)
So not necessarily any faster on PrimeGrid. Better original price than a 2080ti, possibly worse power (although with half the CUDA cores, all the RTX and all the Tensor cores not being used, it may work out less)

The cores are clocked slightly higher and use a different architecture so should show some improvement.
Actual figures (against a base 2080) - https://www.primegrid.com/forum_thread. ... rue#143381
AP27:
2080: 660-720
3080: 290

PPS Sieve: (2 tasks)
2080: 215
3080: 170

DYFL:
2080: 103000-110000
3080: estimate after 15 mins = ~72000
Probably not worth it for pure PrimeGrid.

More figures - https://www.primegrid.com/forum_thread. ... rue#143492
My UPS shows 64% load with it running GFN and 25% load without. It's a Smart UPS-1000 which is supposed to have 700W maximum load which means the 3080 is using 210W.

Some actual runtimes to confirm the earlier benchmarks. The DYFL time is probably a bit slower than optimum as I had a few hours of doing some other tests without suspending it.

Yes, that's the article. John P. Meyers of SETI.USA is engineer and critiques most new hardware. This is another of his comments...
Many of them that didn't do so well in the silicon lottery are crashing, artifacting, freezing up, blackscreening, etc. Because of that, GPU makers will start issuing new BIOS versions that downclock the GPUs so they'll work properly. Of course this means crunching perf will also drop. Not sure yet by how much.
RTX 3090 $1500 24GB VRAM 10,496 cores - ? TFLOPS - 350W
RTX 3080 $700 10GB VRAM 8,704 cores - ? TFLOPS - 320W
RTX 3070 $500 10GB VRAM 5,888 cores - ? TFLOPS - 220W

I've left the TFLOPS out because I've heard the CCs are now single issue instead of double. If true, the 3090 would be just under 15 TFLOPS, if not almost 30 TFLOPS. Need to look into it further
M'kay i believe i have it figured out. What I believe they did was added a second vector float ALU pipeline that shares the same register space and execution control flow. Yes, you can say they have doubled the core count but you should also consider that they are "less capable" cores. Similar to what AMD pulled off with bulldozer cpus. And got sued over.

Basically, each core can do FP+INT at the same time, just like the 2000 series. But it can also now do FP+FP instead. However, when it does FP+INT at the same time, the total TFLOPS are cut in half. *sigh* always with the shady gimmicks

Yeah, as I understand it each CUDA 'core' has two execution units in it, one does FP and the other does FP + INT.

Nvidia are claiming each unit and stating the 3080 has 8704 cores.

Add up the FP and you do indeed get 8704 compute units but for pure INT loads, half the chip is idle (4352 compute units active)

Hi Mark

This might interest you:

https://www.theregister.com/2020/09/24/ ... _shortage/

Seems NVidia got caught out on the 3080 launch and tried to prevent scalpers and bots getting hold of the 3090s that were made available.

It's not clear how well they succeeded, but there are reports of some 30x0 GPUs on sale on ebay at greatly increased prices...which perhaps are scammers or people wanting to make a fast buck.

I think Nvidia must be reconsidering their PR status. No doubt they are paying someones mega bucks, basically to pi$$ people off. Nothing available to begin to satisfy demand.

I also wonder just how the speed increases will pan out in real world calculations in live projects. :?: Some figures seem spectacular, but not all tasks are optimised or able use all the features available. Even the compilers etc will need updating etc.

Hi all

It seems there has been a heist at a MSI factory in China as 40 cartons of RTX3090 have been nicked.

The haul of around 220 GPUs is worth around US $ 330,000.

https://www.techradar.com/news/dollar33 ... si-factory

So, if you get offered one on the cheap from a Chinese seller on any of the e-commerce websites, then you might be getting a stolen card (to which you have no rights to own of course).
