Quoting myself:
Actually it's the 1080 that may be marginally better in terms of dollar-to-throughput.


Damn. My bad. Too tired to think straight these days and was relying on math I did on the back of a napkin last night right before going to bed... and got the fractions the wrong way 'round. Oops :)

Anyway:
GTX 1070 6500 GFLOPS @$379
GTX 1080 9000 GFLOPS @$599

So 6500/379 equals 17.15 GFLOPS per dollar for the 1070
And 9000/599 equals 15.025 GFLOPS per dollar for the 1080

So you'll probably get at least 10% more real-world Seti performance per dollar with the 1070. Theoretically maybe even 15%...

Going to wait until they decide to show us all of their products, not just a first few that come out.


Actually... I just remembered there's a GP102 rumor flying around. IF true then that'll likely be a Titan but maybe even a 1080Ti too :) So if maximum throughput per card is the goal then yes, it may actually show up sooner rather than later.

But again in dollars-to-throughput I doubt the scales will tip dramatically...

However next to no-one thinks there's a chance the GP100 ("Big" Pascal in the Tesla card) is going to show up in a GeForce this gen. So maybe around this time next year...

Again all rumors.

(continued from previous post)

....So comparing the Titan X to the 1070 was a bad idea. The price difference clouded my judgment. Sorry. However the 1070 should be noticeably better than the vanilla 980 @Seti crunching. Maybe 20% better realistically? Too early to tell of course...

But that brings us to Juan's question:
- Will be the 1070 a real winner or is better to go to the 1080?


Nah... maybe for gaming there'll be an edge but not for Seti. Evidence so far suggests that dollar-for-dollar they're likely almost completely equal. Actually it's the 1080 that may be marginally better in terms of dollar-to-throughput. But again, likely not enough of a dif to be important. So I guess the real answer is "whichever suits you best". By that I obviously mean budget, existing power supply, case, number of wanted cards etc.

However the above does NOT take power consumption into consideration. But difference there likely won't be significant either. Because these are same-generation cards. But difs may likely be considerable to previous gen cards. Probably worth the change-over for 24/7 crunchers of multiple high end cards as power savings in dollars could run into the hundreds annually. But we still have time to figure all that out:)

Wiki specs are up now BTW:

Not me, after watching them release the 980 then waiting a few months to release the 980Ti as short time later with specs that equalled or passed the Titans Xs


Not arguing with ya or anything, but the Ti was something like 9 months after the vanilla 980.

As for the Titan, we now know that it's a niche GPU and likely "useless" for SETI. In the sense that most of the extra money you pay is for DP performance (which for SETI-only crunchers is useless)...

Which brings me to my next post...

maybe someone could buy the gpus at normal prices and bring them to you

It's happened in the past.


petri, Kevvy...

Maybe you guys should take the next plane to Aussieland and take your 980s with you. If you can sell 'em within the next couple of weeks you'll have scored a "free"* trip to the land down under :)

*Because whatever money you have left over from the trip, you can invest in 1070s and likely still end up with the same RAC you've got today ;)

Just thinkin' outside the box...

They did skip a process node, and amp the memory/subsystem, so the claims seem viable. Time will tell if it's any good for compute, though the implications of some of the graphics+VR features seem to imply better/more-flexible processing.

For example they mentioned physics based audio processing for VR, which should be heavy floating point oriented, so we might get the raw TFlops we'd like.


Hmmm... reluctant to believe the numbers as far as SETI performance goes but IF I'm reading 'em correctly the 1070 (yes 1070) should be slightly better @crunching than the $999 Titan X?

@$379?

Sounds too good to be true.... Allegedly 6.5 TFLOPS.
9 TFLOPS for the 1080.

(BTW I DID get the 1070 launch date wrong, it's June 10th)

New name's official:

NVIDIA GTX 1080

more updates soon...

edit1: "Faster" than Titan X and TDP @180W AFAICT
edit2: "Faster" than GTX 980 in SLI
edit3: Sorry should have said it's live... Here's the link
https://www.twitch.tv/nvidia

edit4: 1080 $599 May 27
1070 $379 June 3
Going from memory so numbers could be a bit off (not 100% sure about the 1070 release date for example)

Jason beat me to it ;)

OK so it's semi-official it's gonna be Donald vs. Hillary...

Unfortunately I still don't think Hillary can rope-a-dope Trump 'till November.

If Sanders can bring out Hillary's natural-born-entitlement side...

I fear Trump is gonna force Hillary into a mini-meltdown, then the press and Trump-allergic voters are going to pretend it never happened.

Dunno if it'll be enough to make Don president but for now I see no reason it couldn't.

Anyway, that's what my crystal ball is (still) saying.

...award you credit according to how efficient you were (compared to all tasks and tasks in your group of tasks) in crunching the task, [I think in theory, you are supposed to get a bonus if you are faster than the average]


Wait, what?

Who? Who figured this out? Or did one of the Boinc crew offer this bit of info?

"As the European Union begins to disintegrate, who can provide the leadership to save it?

“Nein zu Allem.”...This phrase – “No to everything” – is how Mario Draghi, the European Central Bank president, recently described the standard German response to all economic initiatives aimed at strengthening Europe. A classic case was Merkel’s veto of a proposal by Italian prime minister Matteo Renzi to fund refugee programmes in Europe, North Africa, and Turkey through an issue of EU bonds, an efficient and low-cost idea also advanced by leading financiers such as George Soros.

Merkel’s high-handed refusal even to consider broader European interests if these threaten her domestic popularity has become a recurring nightmare for other EU leaders. This refusal underpins not only her economic and immigration policies, but also her bullying of Greece, her support for coal subsidies, her backing of German carmakers over diesel emissions, her kowtowing to Turkey on press freedom, and her mismanagement of the Minsk agreement in Ukraine. In short, Merkel has done more to damage the EU than any living politician, while constantly proclaiming her passion for “the European project”."

I'll probably have better luck searching for a unicorn but anybody have numbers for v8 (or v7 if not) on stock app doing one WU at a time?


That was poorly written. What I meant was anybody have v8 times for any of these:

- GeForce 9800 GTX - 324mm2 - 140W
- GeForce GTS 250 - 260mm2 - 150W
- GeForce GTX 460 - 332mm2 - 150W or 160W (2 versions)
- GeForce GTX 560 Ti - 332mm2 - 170W
- GeForce GTX 680 - 294mm2 - 195W
- GeForce GTX 770 - 294mm2 - 230W
- GeForce GTX 960 - 227mm2 - 120W
- GeForce GTX 980 - 398mm2 - 165W

changes in architecture that result in the current applications being nowhere nearly as effective on the new hardware as they were on the old.


I could be overoptimistic or oversimplifying or both but:

For now I can't think of (or better, don't know of) a reason that couldn't change overnight. If Pascal's architecture is closer to Fermi and the 460 or 560Ti then I'm guessing the Pascal drivers could roll back into Seti app favor. That's not to say that the old apps necessarily work "out the gate", rather that they happen to be better optimized for Pascal rather than Kepler.

If that makes sense :)

(I kinda got the impression, in hindsight, that Fermi architecture was 100% compute oriented and then intentionally watered down over generations for the sake of gaming & efficiency. Pascal looks to be the same if GeForce cards end up anything like the Tesla that was announced. In other words this could be Fermi 2.0 and it again gets watered down over the generations. It looks like compute gets the advantage this round. Reminder: you guys notice that jump in frequencies on Pascal?)

OK so more rumors flying around that a mainstream GP104 chip will get announced (actual availability unknown) at Computex 2016 (from 31st to June 4th).

A couple of pictures of the chip are floating around which superficially look authentic:

http://www.fudzilla.com/news/graphics/40515-nvidia-gtx-1070-gp104-200-pascal-asic-pictured
http://videocardz.com/59266/nvidia-pascal-gp104-gpu-pictured-up-close

Even if bogus it would still make sense for the GP104 to be in the ~300mm2 range so here's a... brief history in time :)

- GeForce 9800 GTX - 324mm2 - 140W
- GeForce GTS 250 - 260mm2 - 150W
- GeForce GTX 460 - 332mm2 - 150W or 160W (2 versions)
- GeForce GTX 560 Ti - 332mm2 - 170W
- GeForce GTX 680 - 294mm2 - 195W
- GeForce GTX 770 - 294mm2 - 230W
- GeForce GTX 960 - 227mm2 - 120W
- GeForce GTX 980 - 398mm2 - 165W

So while we wait, I was thinking maybe we could see how these cards behave @Seti.
I'll probably have better luck searching for a unicorn but anybody have numbers for v8 (or v7 if not) on stock app doing one WU at a time?
Any other ideas for an apples-to-apples comparison?

For reference my little ION GPU does a "normal" ~0.43 Angle Range v8 WU in about 3 to 3 and 1/2 hours. Poor thing has a 12W TDP :)

You are not the only one around here to have used the phrase 'a-hole'.


Up until a minute ago I was quite certain I was the only one. Now I'm not so sure :)

I guess it doesn't matter. If it wasn't aimed at me then it wasn't aimed at me. Please do a mental strikethrough of all the (now) irrelevant bits in that comment.

Just the personal stuff I got wrong though. Most of the rest still stands as my opinions and/or personal beliefs (or whatever).

There is a group around here that thinks nothing is wrong with their ad hom. attacks on others they disagree with... a-hole this.... stupid that...


Oh dear :)

I presented an argument and you "attack" it with an ad hominem. Ironically the attack is accusing me of committing an ad hominem attack. And you do it by delivering an under-the-belt blow by serving me with one of my disclosed severe allergies: PC dogma

I'd like to help you understand what just happened but I'm not confident I can actually untangle this to a point where it's understandable. I'm not even confident the above paragraph looks coherent :D

I assure you it is. And here's yet another stab at an explanation (since this conversation is obviously being carried over from the Varoufakis thread):

The only way you can truly win this argument (because all you are doing now is scoring brownie points*) is to make the case that my psychopath/narcissist detector is broken**

At this point it may be a good idea to remind you that you weren't the only kid in gifted & talented class and also that we are all now adults.

Alex Storey did not call Major K an a*hole. Alex Storey called a public figure (most of them public servants unfortunately) an a*hole. I seriously doubt you are going to argue that this is not allowed, so on to the next paragraph :)

Now the fundamental mistake you are making: it's your logic diagram
Because you believe:

If Alex Storey calls psycho
->then
->Alex Storey is in disagreement with alleged psycho

Unfortunately your logic diagram can not account for:
Alex Storey has nothing against lightbulbs. He still thinks Thomas Edison was an a*hole.
or
Alex Storey is an atheist who has thoroughly enjoyed a few Dawkins books. He still thinks Richard Dawkins is an a*hole.

Or to go back to my favorite psychopath... Wolfgang wakes up tomorrow and -Hallelujah!Miracolo!- does a 180 back to what Helmut started (which is what he should be doing). I'll be a very happy man. But he'll still be a psychopath :)

-----
*I have no reason to believe your intention is to just score brownie points. If I did, this wall of text wouldn't exist.

** the words "psychopath" and "narcissist" have been and will be used interchangeably with the words "sociopath", "a*hole", and much less commonly with "idiot".

Unless you broke the connector off of the MB you could order a new battery. Which would come with a new cable attached.


Admittedly a much more elegant approach than the brute force of a soldering iron :)

The tape seems to be working for now as I'm not being asked to load BIOS settings any time I power up after switching locations without the main battery attached. I doubt I'll be getting away with it for too long though.

So thanx again HAL!
