Nvidia Geforce 'Maxwell' Thread

[CAT-THE-FIFTH]

I still think AMD were utter nutters for not getting that bus powered HD7850 into retail. It would have made it one of the best performance/watt cards ever released. It
makes me less enthusiastic about the GTX750TI now in light of the info,but I expect many reviewers won't realise it,so I expect another PR coup for Nvidia.

Awesome. I will be chopping my 670 sli in for one of these I think

This reference GTX750 seems to come with a PCI-E power connector:

I do wonder whether peak power consumption goes past the PCI-E spec for the slot,even if sustained power consumption is decent??

Some benchmarks from Nvidia:

It will be interesting to see how it compares with the R7 265.

Galaxy GeForce GTX 750 Ti exposed, can be overclocked to 1.35 GHz

Galaxy is preparing its fully custom GTX 750 ti for the launch.

What we have here is a non-reference cooling solution and upgraded PCB. The presentation reveals all the details I’ve shared with you earlier: the Maxwell architecture, the GM107 picture, comparison to its direct competitor R7 260X, comparison to previous x50 Ti cards and performance figures.

That's a pretty nice overclock, wonder how well 2 of them in SLI at that speed would do at 1080p.

Looking forward to seeing high end Maxwell on 20nm. Could be some real high clock speeds, especially with lower power consumption / heat. Should get some big OC's even on air.

These upcoming cards are going to be beasts..

NVIDIA GeForce GTX 750 Ti (Maxwell) Review

Today, NVIDIA introduced its next-generation graphics architecture "Maxwell", first as a replacement of entry-level product of current generation, GK107 based on Kepler architecture, namely GM107. (M in its codename refers Maxwell as well as K in GK107 means Kepler) Recently (for more than a couple of years) NVIDIA has launched its new architecture every even year, for example, Tesla for 2008, Fermi for 2010 and Kepler for 2012, and this biennial rule made it more predictable that the company will release post-Kepler product sooner or later. Many enthusiasts have been questioning how fast the new flagship GPU compared to GK110. This question may, however, not be answered today. Since today we only got a baby Maxwell.

Video Reviews,

The first low end Maxwell card on 28nm is trading blows with a once high end HD 6970 while using around half the power.. (Check the compute performance as well).

High end Maxwell on 20nm is going to be awesome.

 

[JediFragger]

Everyone has high hopes for high-end Maxwell, esp if they're throwing in quad ARM cores too

 

[Orangey]

Any particular reason they're comparing against a 6970?

 

[vsg28]

Just to show how mid range cards 2 generations later perform better than the competitions's flagship from then.

 

[CAT-THE-FIFTH]

Why not a GTX570 then??

It's not really performing better though at least in a gaming sense.

TH just loved the card but I saw the following in their review:

http://media.bestofmicro.com/2/W/422600/original/01-GTX-750-Ti-Complete-Gaming-Loop-170-seconds.png

Non-Contact Direct Current Measurement at the PCIe Slot
Non-Contact Direct Current Measurement at the External PCIe Power Supply
Direct Voltage Measurement 3.3 V / 12 V

For brief periods its going massively pasted its rated TDP and power consumption and boosting highly.

Those are not full system measurements but card only measurements.

TH says the card consume 60W on average but the problem is look at how high the card power consumption can deviate from the median.

It might be interesting to see extended tests in a smaller case with the card. Cards like the GTX760 with reference coolers(which are not great) had issues with throttling over extended periods.

Looking at the problems reviewers have shown with both AMD and Nvidia boost tech,I really think perhaps reviews need to do more stressful testing of cards.

All I think it does is inflate scores. At least CPU Boosting is very conservative. GPU boosting does not seem that way with the latest AMD and Nvidia GPUs.

270X performs better than a GTX 580 and 6970. If we didn't have generational performance increases something would be very wrong.

Nvidia's Boost 2 does inflate scores if they are short runs, on a cold start run they boost very high before coming down once warmed up.

Anyway. i find that "141 Watts Max" power usage very interesting, its 240% of its TDP.

Is this architecture so efficient in a limited range, once outside of that range the power usage sky rockets? its actually spends a lot of time at 90 Watts. which is no different to the R9 260.

 

[Suarez7]

Yep all cards once running past their normal speed seem to use a great deal more power, I'm sure I seen a post here of a guy with one 780 pulling 800w from the wall with an overclock.
