New details about Nvidia`s Maxwell

Maybe, I dont really know how those to fit together. You could be right

GTX 750 Ti
640 cores * 1085MHz = 694400

GTX 650
384 cores * 1058MHz = 406272

694400/406272 = 1.71
Meaning if GTX 750 Ti was based on Kepler, it should perform 71% better. Give or take other factors like bandwidth and ROPs.

But we know that GTX 750 Ti is 100% faster than GTX 650.

Spoiler

GTX 650 (non Ti), TDP = 64W
3DMark11 score: 2759

GTX 750 Ti, TDP = 60W
3DMark11 score: 5611

Which means that Maxwell is roughly how much better performance/core:
100/71 = 1.4 = 40%

Its probably a little bit lower when one look at games and not a benchmark. So very close to the +35% over Kepler

 

If anyone wonders, here is mention of several Maxwell cards:
INF v4.146 - News - LaptopVideo2Go Forums

Clevo also just updated their driver to include many 800M cards:

perfect, this with ASUS new ROG G750JM G750JS G750JZ with 860 870 880M they are coming even 28nm maxwell is welcome or an 870M=680M OC (1344 cores )

 

I really hope GTX 860M is Maxwell. If it is, it means it have 128 more cores than GTX 750 Ti, which scores the same as GTX 680M in 3DMark11.
So we can expect a bit lower score than GTX 870M , but with muuuch lower TDP.

 

I didnt saw that 870M leak it's powerful, is it a GK104 ?

 

It looks like GK104 but with 64bit less bandwidth and 8 ROPs disabled compared to GTX 680M.

that 870M is a monster it scores like (or may be a little less than) a 780M @ stock i think

 

wait for 20nm is too long for mobile. Desktop Maxwell in summer only.

But man, these performance numbers I talked earlier about, make me anxious to buy the bad boy.

 

what's the TDP of this leaked 870m? the old 770m used 75watt so that prevented it from being used in thin laptops, but the 765m was 60-65watt and that was enough for thin light laptops. if the 870m is 60watt then it should work in similar case sizes as the 765m!

 

Higher TDP than GTX 680M (1344 cores @ 720MHz) but lower than GTX 880M (1536 cores @ 967MHz).
Higher than 60W, thats for sure.

Unless its not a Kepler, but im 99% sure it is.

 

There was a misconception with the release date of Titan Black. Latest leaks point out 18 of February.

If true, u all should be praising Huang(lel) as the single gpu room has now been freed. Aka, Maxwell cards should be real soon now, especially leaks!!!!

PS: 790 should arrive with/extremely close to Maxwell along with better SLI scaling.

 

IDK, honestly. They just advert it, trying to pay off with AMD when they released their 280x and below first.

 

how can you tell if it is kepler or maxwell? can you infer from the specs of the gtx 750 ti which is known to be maxwell? like similarities?

 

Nvidia have been milking Kepler for far too long now. We deserve Maxwell. It was really meant to release in 2013 but was pushed in to 2014.

We have
14 different GK104 GPUs out there
6 different GK110 GPUs

lol :/

I cant prove it, but its typical Nvidia to use an exisiting GPU with the same core count (GTX 680M) and either increase clocks or nerf bandwidth/ROP count and rename it to something else, thus having a "new" GPU to sell.

Plus someone here overclocked their GTX 680M to around 1GHz which GPUz show 870M will run at, and scored exactly the same in 3DMark11

Man, I hope Aorus releases a X7 with 2x 860m. That would be amazing.

Also, maybe the 870m is being read wrong by GPU-Z?

 

Well its not impossible that it is a 896 core Maxwell I guess, I`m just saying the benchmark do line up with a Kepler.

We will eventually find out. Hopefully on Feb 18th

 

i think cloudfire is right and it is a rebranded kepler and the TDP should be over 100watt

the gtx 750 ti desktop card is a known maxwell and these are its stats
GTX 750 Ti, TDP = 60W
3DMark11 score: 5611

if we are to expect 60W chips in our slim light laptops they will perform very close to this

if the 860m is a maxwell i don't see it performing any better without raising the TDP over 60watt right?

 

why 18 feb exactely ?
edit: the 870M is gonna eat a lot of watts the 180W power adpater of the g750jx wont make it (it was designed for the 75W of the 770M) they will be obliged to add an 230W adapter (G750JH).

 

the gtx860m cant be a full GM107 plus an OC, they always downclock mobile versions (even if they can add more mhz's i dont think they will)

 

If the 870M runs at 60W then why not overvolt it to 100W and OC it! It will be done and means the jump goes from 35% to 60% increase on 28nm alone LOL

I am stoked though as my M15x was designed for 75W tdp gpus in mind. It struggles with 100W+

 

I've found the TDP figures for 8x0M series, here.

840M -33W
850M -45W
860M -75W

Are these correct? I expected lower TDPs.

 

They are kind of exagerated, they calculated it as it was kepler card, only the 880M 870M will have 90W-110W TDP
the 860M if it is maxwell will have max 60W TDP as i expect..

860M you mean right ?

 

Techpowerup change their specs on unreleased models so many times its hard to take them seriously until they post official specs which have been confirmed.

https://www.google.no/#q=nvidia+february+18

 

Yup, it does look like GTX 860M is based on the new architecture, Maxwell

PC21.fr GE60 with GTX 860M listed

 

Titan`s launch was literally decided by AB in matter of days. Feb-march are speculated dates.

GK110 has been out long enough, Maxwell is near now.

Most importantly, where the heck is 790?! I know an approx., release date but why so long?

 

First performance review of GTX 750Ti which is a Maxwell.
It is a 60W GPU and is pitted against a 115W GPU (Hawaii) from AMD. The results should speak for itself.

 

Agreed that Maxwell looks promising perf/watt. Note that R7 260X is Bonaire XTX not Hawaii though.

 

It appears that maximum settings have been used for each game right ?

 

Im not sure but I`d say pretty close to that yes.
In average 60W Maxwell is about 20% faster than 115W Bonaire. Respectable result

 

Well its been confirmed guys. Aida 4.20.805 Beta information have been leaked,
We will have two new 28nm Maxwell`s coming most likely this month.

GTX 860M is a GM107 Maxwell.
GTX 850M is a GM107 Maxwell.

Most likely GTX 860M is a full GM107 with 640 cores while GTX 850M is a 512 core GM107. ( See the desktop equivalents here)
Expect 30-40W TDP on these babies while GTX 860M perfom like a GTX 770M (Around 75W) if not slightly more :thumbsup:

There is one additional scenario that can happen:
GTX 860M GPU-z was posted a while ago but it was using the updated GPU-z that can`t detect Maxwell properly. If that screenshot is not a fake, GTX 860M will actually have 768 cores which means it will perform better than GTX 750 Ti since it have 128 more cores. We are talking GTX 680M performance but with TDP of maybe somewhere around 50W.

http://wavilon.info/software/16251-aida64-extreme-edition-4202805-beta.html

 

Cool, so maybe we can expect that 850m performs like a desktop 650 and the 860m like a desktop 650 ti, not bad

 

Depends. I edited the post a little before you quoted me.
If GTX 860M is a 640 core Maxwell, we can expect maybe 10% faster than GTX 650 Ti but with 60% reduction of that TDP.
If GTX 860M and the previous GPU-Z screenshot I posted is not a fake, It means it have 768 cores. We are talking 20-30% faster than GTX 650 Ti and with like 50% less TDP

Either way. GTX 860M will be amazing.

 

50-60% less TDP with 20% improvement is a significant win. That means 765m performance in a 35-40W TDP. Pretty phenomenal. Now what does this mean for an 870m and also when they hit 20nm? I'm hoping Intel can throw us a win with Broadwell with 35W TDP quad cores that don't heat up like a furnace and have better performance than the current 47W quads.

 

I`m pretty sure GTX 870M is a GK104 based on 3DMark11 score. It will be exactly like when Kepler launched. Its quite funny how history repeats itself

GT 640M/GT650M and GTX 660M was GK107 Kepler when they launched in March 2012. We also had GTX 670M and GTX 675M which was Fermi.
Now we have GT 840M/GTX 850M and GTX 860M which is the first Maxwell. We also have GTX 870M and GTX 880M which is Kepler



Yeah, so much reduction in TDP while performing significant better is great news for everyone. It bodes well for the upcoming big Maxwell`s. Its sad that Nvidia have to wait for TSMC`s 20nm to be able to build the chips, but it is what it is.
I`m extremely curious to see the temperatures with GTX 860M. There is a guy at overclock that test his desktop GM107 (GTX 750 Ti) right now and he max out at 47C whe overclocking from 1100MHz to 1300MHz. So one could imagine a very cool GTX 860M.
Not to mention it will be interesting to see the true performance of GTX 860M and GTX 850M.

I too hope Intel delivers this year. I`d hate to see another +5% improvement. And I hope temperatures have improved there as well. But you know, they have reduced the die even further :/

 

I guess I'm just hoping that we'll be able to see 192-bit cards in a thin and light due to the low TDP. Probably be a 970m by end of this year with Maxwell 20nm, or 870mx. Either way 870MX with 192-bit vRAM and 50W TDP would be spectacular. Just Intel needs to work on TDP on their chips as well. I'd love to see a 25W quad core even. I mean they have an Atom quad core at 2-4W TDP, but no quad until 37W and those are just 47W chips with reduced TDP.

 

now this seems really interesting.
just hope they keep the power usage down and the frequenzies way uppp

 

The 860M and a 37W 4702 sounds like a match made in heaven for a nice thin and light that can game and manage heat.

 

Problem is that the 4702 runs just as hot as the 4700. They just cut down the TDP and clocks by a bit so it basically doesn't throttle. They really need to design a quad core around a 35W TDP not a 47W (and really should be closer to 55W) and just limit the TDP.

 

850M with ~30W TDP is absolutely winner for me, hope it will get few thin 14" designs with 15W Intel i7 CPU, I especially think for the successor of Gigabyte U24F.

 

Welp, now I feel kinda sad for buying a 770M laptop when I did (its still in the build phase atm). Oh well.

 

I still can't believe Maxwell on 28nm is giving twice the performance per Watt of Kepler. I know all the leaks point to that level of performance, but I just can't believe they can do it without shrinking to 20nm. (Cloudfire, you don't have to convince me, I've seen all your arguments, and they're good and make sense, but I'm gonna wait for the official reviews - I just can't believe it!)

 

2nd case : P6600 3dmark 11 wow !
1st case : equals a 770M with a low TDP..

the GTX 870M will be a monster even if based on Kepler (max 90W TDP i expect) 7.1k 3dm11 is way more than the low clocked 680M and not that far from the 880M (for people who doesnt have kepler in their lappies, it's a massive improvement)

 

Can't feel bad about that.... there is always something new coming, gotta buy when you are ready and need the machine. We've all been there!

 

I don't exactly need the machine atm tho =p (my desktop is fine for me currently, the laptop is a bonus). I just wasn't expecting the refresh to offer me anything I couldn't overclock to on the 770M. At this point, it looks like I'd much rather have a GTX860M with lower TDP, seemingly more overclocking potential, and equivalent stock performance at a lower price point.

 

hehe, I`m just as curious as you. I still want to see solid evidence before believing anything. But if its a 640 core Maxwell, it will be a very good decent gaming card.
TDP of the GTX 750 Ti is 60W. With mobile GPUs we get lower voltage, they are binned, and the clocks are a little lower. It should have a pretty low TDP

Nah, GTX 870M is a dead card even before it release. Its just a GTX 680M with really high clocks. Which makes it a little boring because you probably can`t overclock it much. But if you want good performance right out of the box, its a ok card. But it still only have 192bit bus vs the GTX 680M 256bit, so you be better off with buying GTX 680M imo.

That is another thing that interest me. Wonder how Maxwell does with overclocking. I have a feeling they can go pretty high based on the fact that GM107 desktop GPUs are clocked over 1GHz while most Kepler cards was sub 1GHz.

 

1) This is some terrible performance/clock on 750 Ti. Huge OC- diminished gains. It was not proper with Kepler, but Maxwell brought it even lower. Guess, 20nm should fix it

2) :laugh: 860M- 680, 870m- OCed 680m, 880m-Even more OCed 680m. Mobile gpus stuck for ages..

3) if 860m is only 30% better than its predecessor, 760m, it is not A BIG improvement as a lot are claiming.

 

exact, i was talkin about out of the box perf
but yes the 860M OC can be a monster too with such a low TDP especially if it's 768 CC

 

The most upsetting part for me is that the 860M should be at a lower price point, and is at the sweet spot for me for performance, so I would've been able to afford an addition like a 240GB SSD instead of 120GB.

 

double post

 

Well reviews of GTX 750 Ti should be here tomorrow I think. As well as maybe official reveal of GT 840M, GTX 850M and GTX 860M for notebooks.

Fingers crossed
