i like the front facing power connector on the RTX 2070 FE/ref card. i dont think any of the AIB's will keep that though. i know the EVGA doesn't.

it's a toss up on if this card performs at 1080ti levels on SETI, the compute tests vary on performance depending on which test. tough call if it doesnt. does anyone know which compute test most closely reflects SETI workloads? basically which one would be the valid test to compare different card models

2070FE = $600 and can be ordered from Nvidia
non-FE AIB cards could be had for as low as $500 (not sure on stock right now, looks like EVGA has some in stock for $550)
used 1080tis can be had for ~$500 (buy EVGA)
used 1080s can be had for $350-400 (buy EVGA)

gaming performance puts the 2070 very close to the 1080, and some compute tests are close as well. power use is about the same between the 2070 and 1080 as well. so maybe the used 1080 is really a better buy? performance per dollar at least.

i'm going to play with my system, and probably power limit the 1080tis to 200W each, then OC them to keep core speeds up to normal. If the behavior is the same in linux as it is in windows, this should force the core voltage to lower. basically getting the same performance with less power draw. (it works for mining at least). power draw on SETI seems to build as the WU progresses, in most of my cases i only see it exceed 200W on the last 25% half of the WU processing or so.

The AnandTech Folding@Home Single-Precision and the N-Body Simulation 1024K tests would probably be the best match for Seti performance from the AnandTech reviewer.

The OpenCL FFT Single-Precision and the Mini-Nbody tests would best match Seti performance for the Phoronix reviewer.

I've looked at EVGA, while I do own a couple of EVGA motherboards, the video cards I like are all blowers, I did manage to find 1 EVGA 1080Ti blower card for $599+shipping, but that's it, MSI or Zotac are a bit more numerous($565-$600), Asus($540 min) and Gigabyte($550 min) are available in the 1080Ti as blowers, the 1080Ti's with 2 or 3 fans I ignore since I don't like dumping heat back into the case to heat up the cpu with.
YMMV with prices, since they change at will.

That’s fine. But blowers don’t cool the GPU nearly as well as a multi fan model.

Ah, so that is the distinction? A blower is a single fan air cooled model?

A blower is a fan that exhaust hot air outside the case at the back though the bracket (does not exhaust hot air back inside the case)

Isn't that a sucker?

As in it sucks the hot air out of the hot innards?...

... Or just another ducted cooling fan? :-P

(Joke alert that was :-) )

A "blower" type fan would normally be described as a radial, centrifugal or squirrel cage fan.

for the more visually minded folks.

a blower sounds good in theory, but in reality the cool far worse, and the cards arent able to perform as well being thermally limited. they will run slower, hotter, and with more noise than an open-air style cooler.

For a single GPU in a large, well-ventilated computer case (or in the open air), the "throw the hot air all over the place" type will be better.

But for multiple, close-packed, GPUs in a restricted space, the open cards will slow each other down by taking in each others pre-heated air. The blower style is better in that case.

Hmm, Perti's FE cards seem to perform quite well :D
Although I believe he has a squirrel cage fan blowing in the side of the case.

he's also stated that the GPU temps are over 80C and he has to remove overclocks in the summer to keep things in thermal limits.

i'm not saying the card wont run at all. just that they will run faster with better cooling. i personally dont want my cards running 80+C all the time. which is why I and many other invest in water cooling, or using risers to space the cards out to get better airflow.

Technically I could buy an MSI GTX 1080 AERO OC card for $370 or a bit less which looks like an excellent buy for someone, the Aero is a blower and is factory overclocked to 1632, other blowers I've found run at 1607, I say technically cause I need to replace 2 of My home's windows and that will be $810.87 for the windows, I just don't have enough for both at the moment and some debt reduction and My credit score going up, yeah My score is going up.

Computer case side panel removed and a duct fan aimed directly at the 4 GPUs.
The cards are FE with single blower-type (squirrel cage) cooling fan @100% that blows the hot air out at the back.
Once a month compressed air does wonders removing the dust from the inside of the cards.

what's the ambient temp? you mentioned in the past about summer temps causing heat issues, so it would stand to reason that winter temps would be much better, no? looks like its 0-5C in Finland these days.

i dont normally run my fans at 100% because it's not needed. but as an apples to apples comparison, heres my smi output with them cranked:

normal i leave on auto fan control, and let the cards sit around 65-70C with 30-50% fan speed. ambient temps about 18-20C where the computer is.

With the aircon running the ambient temperature here is 27°c. No aircon, it's getting back up around the low-mid 30s

Greetings,

I have been reading a lot of reviews on the new RTX 2070, 2080 and 2080Ti graphics cards. It seems that quite a number of people have had issues, mainly that the cards die soon after installing and using them. I read DOA, died after 2 days, after a week, after 10 days, just under 2 weeks... Not looking good right now.

Even though I could get one right now, I think I won't. I'll keep reading reviews and watching to see if the prices start to drop to a reasonable cost.

Another thing too is that programmers need to re-write code to take advantage of the ray tracing.

I did watch some bench marking videos and the 2080Ti took center stage. But... right now the best bang for the buck is still the old 1080Ti.

I'd still like to see how a 2080Ti would do on SETI though... :)

Have a great day! :)

Ouch.. a bit rich!

$4,000.00? Possibly gone up in a puff of smoke, if they act like some 2080's and 2080Ti's on the HardOCP.

No I don't have one and I have no plans to get one, even a Titan Volta seems like a safer bet.

What I can't tell is if the Quadro line which also uses these apps for processing are actually any better than the Gtx and/or Rtx cards? Quadro prices for current cards seem to start at $6,000.....

Then there are those "Tensor" cards. I can't tell if they would run our gpu apps at all. And at least some are wildly expensive.
