Gigabyte P35g V2 News

That seems unlike xotic to give false info. Anyone with the laptop able to go into hardware and confirm that it indeed is Kepler?

It is absolutely, 100%, without a doubt Kepler.

 

Better battery life, no doubt.

But in terms of cooling they are similar, I think. Have to say that my Apache runs probably cooler than the average, don't really know why.

And after removing the back cover temps are simply amazing, 32° in iddle and 53° after a 3dmark11 run, CPU clocked at 2.4 GHz and with UV -75 mv

Can you shoot me a PM about who told you this please. We want to make sure we are providing accurate information and will review this with the rep you talked to.

 

No I think you just misunderstood
Because the p34g v2 is actually gtx 860m maxwell
And the p35g v2 is gtx 860m Kepler... They putt Kepler in the p35g because it performs better
But yes I think you misunderstood what the representative was trying to say.

Cheers

 

Kepler does not perform better...

For the 860m omg Offcourse it does lol !

 

Um, no. It doesn't.

Benchmark show it's the other way round.
860m Maxwell ist slightly (5-10%) better than 860m Kepler, and uses less power (~60%)

The 870m Kepler outperforms the 860m Maxwell nonetheless by ~30%.

No, I do not have the hyperlinks to the source.

 

I ended up ordering the P35G V2 from Gentech. Thanks for all the impressions and information guys. Looking forward to this as my current laptop is more than 5 years old now.

 

Great!
When will it arrive? I starve for a legit review of it, even so I would prefer a review of the P35W

 

But i have
Review Nvidia GeForce GTX 860M Maxwell vs. Kepler - NotebookCheck.net Reviews

 

thats not what gigabyte stated.....

 

Well, Gigabyte is wrong.

 

"Contrary to our expectations, both GPUs are very similar in regard to the power consumption." TDP != actual power consumption.

 

I would rather have Maxwell anyway. It's a new architecture with a lot of room for improvements whereas the Kepler architecture is becoming outdated (it's been used since the 6XX series).

Disappointing that they had to cheap out and use kepler while everything else is pretty solid. Considering this laptop is priced a fair bit higher than the asus and the y50 you'd think they would just get the current version of the same card. I was eyeing the y50 at first but people were saying how atrocious the viewing angles were, and since the screen is what you're looking at all the time, it makes no sense to cheap out on that for the sake of a better card (unless you're hooked up to an external monitor a lot then that's moot).

 

I'm skeptical about that one article that everyone's citing for the 10% value. All of my own benchmarks have been better than what they got for the Kepler card. I did Tomb Raider and Metro Last Light a few days ago, and today finally figured out how to duplicate their DotA 2 benchmark. My Tomb Raider was only 43.3 vs their 43, but Metro Last Light was way better at 27.7 vs 23.7 and DotA was even more significantly better at 72.7 vs 58.3. My DotA 2 value was still lower than their Maxwell value, but their Maxwell number was also better than their number for the 870m!

After re-averaging with those new values, Maxwell's advantage for those 16 games drops to 7.4%.

I'm going to try to get numbers for Bioshock Infinite as well.

 

Even if maxwell performance was identical, I would assume the better efficiency would lead to lower temps which could possibly lead to better overclocks?

 

So far I believe that's just conjecture and that no actual tests have been done. And I'm still trying to find temperature readings for the Maxwell part that I can directly compare to what I've seen for the P35G.

 

The problem really isn't that simple. Temperature also depend on the cooling of the machine. Here is an example of Maxwell 860M running hotter than Kepler 860M: http://forum.notebookreview.com/msi/742589-msi-gs60-ghost-ghost-pro-thread-30.html#post9610119.

The advantage of using Maxwell, it seems, is that you can have a smaller die size: Review Nvidia GeForce GTX 860M Maxwell vs. Kepler - NotebookCheck.net Reviews, so that manufacturers can fit more parts in the chassis or design the airflow more easily. But a smaller die also means a smaller surface area and thus worse thermal conduction. So in the end, even though Maxwell has much better efficiency, it is negated by the larger die size (and also possibly more aggressive cooling) of the Kepler variant. As long as performance wise and temperature wise the machine with Kepler 860M performs similarly to the machine with Maxwell 860M, there is no real reason to believe the Maxwell variant is better. You may say that if Maxwell is actually used in this machine and the cooling system is as powerful as it is now, the machine would run cooler. But since such a machine doesn't exist there is no point to it.

As for overclocking, I'm not experienced enough to say anything about it, but how performance and temperature scale with overclocking in these two variants is pure speculation without actual comparison tests.

 

Ah, makes sense. Well as long as performance is about the same it really doesn't matter. Since you have this laptop, how hot does it get if you're using it on your laps NOT gaming. Just web browsing, chatting, videos, etc etc, but no 3dmark or games.

 

I'm getting it tomorrow. I can post some impressions if I have time tomorrow.

 

I've seen the CPU go up to 60 degrees in those situations & if you have it on bare skin it's going to feel a little hot in the back. But even something as simple as moving the back of the laptop to rest on my knees fixed that. It usually hovers around low 50s for me though.

Will yours have the stock paste or the IC Diamond? I got the IC Diamond with mine, and I'd be interested to see how that compares to stock.

 

Honestly can't imagine the temps be too far apart between stock and IC unless they somehow did a poor job applying the stock and outstanding job on IC, or vice versa.

 

I also got a repaste to IC Diamond. I think usually repasting lowers the temp by 1-5 C, depending on how well the thermal paste is done for stock and repasting.

 

Even if the performance difference is not too significant between maxwell and Kepler, it is still brand new architecture compared to a one thats been used for around 3 years. Nvidia will likely be more likely to support maxwell with new drivers and other updates than kepler

Anyone tried installing Windows 7 on either the P35G or the P35W (or hell even P34)? My college is requiring Windows 7 (why I have no idea) and was wondering if any features/drivers were lost or if the hardware became more unstable with a install of Windows 7, just in case they actually require us to downgrade.

 

Short answer: Xotic PC and Gentech PC both offer the option of Windows 7, so you should contact their support and ask them if they're sure Windows 7 will work fine.

Long Answer: On Gigabyte's website, they have Windows 7 and 8.1 drivers for download for the P34G but only Windows 8.1 drivers for the P35G and W. However, most of the P35G/W Windows 8 drivers should work fine on Windows 7 based on three things: 1) The P34G shares many drivers with the P35G/W, 2) When you look at the P34G drivers, you can see that most of them are the exact same file for Windows 7 and Windows 8.1, and 3) if the Windows 8.1 drivers are the same version between the two machines, then you can probably use the Windows 7 one from the P34G on the P35G/W (I'm totally making that up, but it sounds reasonable). If you go to the drivers pages right now though, you have to contend with the fact that Gigabyte is apparently terrible at updating their web pages, so even though, for example, the touchpad driver versions don't match for the P34G and P35G on the web pages, the P34G driver version does match the P35G driver version that they've already released via their Smart Update utility. Sorry if this sounds confusing. I just really don't know how to explain it well.

Probably not until next week since I opt for paying by check to GenTech PC for the discount. crawnit and cnzqy1 can probably given a better review, but I'll definitely do my best to share my impressions. I was bummed by the whole GPU not being Maxwell, but after all the research done (especially the comparison between MSI's last year model GE60 to this year's GE60), Maxwell doesn't seem to yield that much of a significant advantage in terms of lower power consumption and lower heat generation. Not to mention, the notebook check article and the video that was linked to.

LIke crawnit and cnzq1, I also ordered the laptop with the IC Diamond paste (and the free 12 GB RAM upgrade).

 

What about that kepler overclocking capabilities?

Maxwell's are amazing, though.

Yes and no. It's a new architecture, but most of the changes are related to power and performance. Since tests have established that Kepler 860M and Maxwell 860M are not that different in these two aspects, the real differences are things mostly irrelevant to gamers such as PureVideo improvement. As for drivers and updates, NVIDIA supports their GPUs for a long time. The newest drivers still support GeForce 8M series, and that's 2006 and two generations of architectures ago (including Maxwell). Also, I believe when they decide to drop the support for 800M series, they will drop it as whole instead of dropping individual cards, because otherwise it's too confusing for end users.

Most of the stuff you see in this thread: http://forum.notebookreview.com/gaming-software-graphics-cards/751352-860m-beast.html, is referring to a single machine, Asus G750JM. It has a 17" chassis, as well as an elaborate cooling system. That machine is designed for gaming and overclocking, and it shouldn't be too surprising that it's good at OCing. I'm not sure if you can get similar results for a Kepler 860M with a machine that has similar cooling capacity, since no real comparison test was done. As for this machine (P35g V2), you probably don't want to do too much OCing, because you'll hit low 90s easily and also get throttling, which in effect limits how much you can OC.

 

actually yeah... on my p35k i lost the fast boot, i didnt have UEFI windows anymore, the drivers are old and the gigabyte software is completly outdated for windows 7........ had to install windows 8 drivers and gigabyte software which some worked and some didnt....

its up to you if you can live with old drivers and losing the fast boot....

 

man.... look at the specs of them both! stop reading reviews they arent accurate as each system is different
860m kepler has 1,152 cuda cores... while maxwell only 640
kepler has faster memory clocks....
maxwell only has core speed..... which isnt even that big of a differance.
its nothing compared to kepler.
its all a marketing strategy for maxwell but in reality kepler 860m is better than 860m maxwell
my P35K with a gtx 765M outperformed my friends msi 860m maxwell

i sold my p35k to get the p35W with the gtx 870m
ill be getting it next week... ill do a review

 

I'm sorry but I refuse to believe that a 765m would outperform an 860m maxwell. Stop spreading false info. All documented evidence thus far shows maxwell is on par with Kepler and in most situations offers a small but noticeable advantage. Please explain why Nvidia would spend 3 years developing an architecture that is worse than their previous one

Double post

 

nvidia hs been developing maxwell for the past 3 years for desktops to begin with... youll see it later on
as for notebooks we seen it all... anything 860m and under can be maxwell but thats it for notebooks this year.
and the benchmarks youv seen are all kepler not maxwell/
thats why the kepler 860m is better than 765m

 

..obviously Kepler 860m is better than the 765m, which is also Kepler. What the Kepler 860m is not better than is the maxwell 860m.

Notebookcheck has already done that comparison with synthetic benchmarks and a bunch of games. The Maxwell 860m does slightly better than the Kepler 860m. Both trounce the 765m.

Review Nvidia GeForce GTX 860M Maxwell vs. Kepler - NotebookCheck.net Reviews

 

During a full 3DMark (2013) test, the max CPU temp is 88 C, and max GPU temp is 83 C (auto fan setting). This laptop has IC Diamond thermal paste and was ordered from XOTIC PC.

 

I get 90 C and 81 C on that test using Auto fans.

 

Then they are pretty similar. As for the graphics score, it is also very similar to the Kepler 860M score in: Review Nvidia GeForce GTX 860M Maxwell vs. Kepler - NotebookCheck.net Reviews (~3100 for Fire Strike Graphics Score). But this synthetic test seems to exaggerate the performance difference between Kepler and Maxwell.

As for noise, it's bearable at maximum and the fan does not jump back and forth significantly (much better than MSI GS60 in this aspect) during normal usage. It's not silent like you would expect from a MacBook, but it's good enough.

My main complain for now is probably the keyboard. It's not horrible, but it's mediocre at best compared to the other laptops I tried. A little flex in the middle part, and the travel distance is too short for my liking. Definitely not as good as GS60.

 

What about temps in a 3dmark11 run?

Sent from my Nexus 4 using Tapatalk

 

I didn't try it since 3DMark 11 is an outdated benchmark. I would imagine it to be lower but it's hard to tell without actually testing it.

 

I've read it is the most reliable benchmark and probably the most used bench for benchmarking with oc values..

Sent from my Nexus 4 using Tapatalk

 

While it's probably true that 3DMark 11 is more widely used for benchmarking OC, for the purpose of benchmarking in today's gaming environment the new version of 3DMark is more superior. Although for the purpose of benchmarking high-end GPUs, only the Fire Strike score in 3DMark (2013) is really relevant. Also see: What's the difference between versions? (i.e. why is 3dmark more expensive than 3dmark 11) :: 3DMark General Discussions.

 

Another question, how are the hinges on this laptop? Dell makes some fairly solid hinges, but the first Sager I owned many years back started cracking at both hinges after like 2 years, like REALLY bad cracks not just tiny ones.

Also I have never used a machine with optimus (current system disables it completely), is it possible to lock it into integrated only if you know you won't be gaming anytime soon? Or do you just have to hope that optimus works and the geforce isn't running in the background?

 

Build quality looks solid, but again it's something you don't really know until you use for long enough.

Optimus enables dGPU on the basis of what program you are running. As long as you don't open games dGPU sits idle (still draws power albeit a small amount). You can enable a tray icon to see whether the dGPU is being used.

 

hey if you're talking about the p35g then i can answer that, its the same chasis as the p35k and i used it for about 6 months and it seems to handle well but one thing that you must do and i had everyone in the forum do cause we all had the same problem is that quality control isnt good, yes it might come flimsy and you need to open it up and tighten all the screws again. even if you putt it on a flat surface youll notice its lifted at one end so if you tighten all the screws it will be solid and great
here is my unboxing when i got it from gentech pc
http://forum.notebookreview.com/gigabyte/720395-new-gigabyte-p35k-post9452720.html
literally its the same as the p35g in term of chasis

And for the record....... the fan noise will Effin drive you nuts lol. in public you cant game cause you'll disturb the whole town lol.... i always wear a headset

 

Yup, I had that same problem. If I hadn't taken off the back to install an SSD and then screwed everything in again, I would've assumed I'd gotten a bad unit or something.
