Nvidia Maxwell

I think a lot of people we're expecting to here some news on Nvidia Maxwell at CES 2014 but we've heard nothing! It's quite frustrating because in my opinion the GTX 700 Series is quite clearly a Filler/Delay tactic to give them more time to work on Maxwell.

The thing I find quite strange though is usually No matter what it is, you'll start to here rumors about upcoming technology that's only a few months from release however there's been absolutely nothing on Maxwell except for speculation it's going to be released in 2014 in Q1.

However a lot of people just expect that to be the Entry Level to Mid Cards on 28nm Fabrication an then Big Maxwell will release sometime in August or September on the newer 22nm. Is there any new news anybody can tell us because I just want to hear some proper confirmations for Crying out loud on what's going on. We all know Maxwell is going to be a Big Leap unlike Fermi to Kepler.

I know that these cards will most defiantly have ARM technology on them but what at the very least what kind of performance output do you expect we'll see from these cards?

I too have been thinking about this. Hopefully we'll see something soon.I find it very hard to believe they'll release Maxwell at a mid level because Nvidia and AMD alike nearly always release their flagships forst to create the buzz and then work their way down

All info so far points to it being a Q4 release but until Nvidia actually release some info all we can do is make up rumors and moan and moan and moan and moan.

there isn't going to be any info on maxwell at ces.
the 780 pretty much came out of nowhere, they won't leak anything that early.

This is the most up to date information I can find so far, but it could be based on a lot of speculation, however I think there's probably a lot of truth to the design direction Maxwell will be taken in

Alleged NVIDIA Maxwell Architectural Specifications Unveiled

Its common knowledge that NVIDIA is going to introduce their latest Maxwell architecture this year which will introduce a robust new architecture design featuring new levels of graphics performance in both gaming and the compute world. NVIDIA has plans to introduce four chips next year which include GM100, GM104, GM106 and the GM108. Compared to Kepler, these new NVIDIA Maxwell chips would feature a slightly enhanced SMX unit structure and made some optimizations so that the double-precision algorithm logic unit can now be used for the Single-precision too supporting all the new SP instructions.
Instead of 192 ALUs, a single SMX unit would now feature 256 ALUs which would reduce the DP rate of Maxwell down to 1:4. While technically this looks like a downgrade over Kepler, the actual performance would boost the SP numbers over Kepler. This will save power when using SP performance since the unused processes of the DP ALU would be turned off. NVIDIA also made some changes with Cache Hierarchy big time with Maxwell with the addition of two registers per SMX unit and threads with a huge amount of registers can now run in parallel of each other. The L1 cache is supposedly increased to 128kb compared to 64kb on Kepler and can be used as shared memory too. It can be split between the cache and shared memory in the following steps - 32/96, 64/64, or 96/32. Just like Kepler before it, NVIDIA Maxwell would feature 16 TMUs (texture mapping units) per SMX.
In addition to the L1 cache, each GPC (Graphics Processing Cluster) would also feature its own 768kb of L2 cache serving as the instruction cache of the SMX. As for the specifications of each NVIDIA Maxwell chip, you can find them below:
NVIDIA Maxwell GM100:

The NVIDIA Maxwell GM100 chip would consist of 8 GPCs consisting of 24 SMX modules (3 SMX Per GPC), 384 TMUs, 6144 Cuda Cores, 8 MB of L3 Cache (8 L2 cache’s per GPC), 64 ROPs, a 512-bit interface followed by a VRAM upto 8 GB GDDR5 operation at around 6 GHz. The GM100 is supposed to replace the high-performance GK110 chip so its going to end up in both GeForce parts and Tesla parts. It will probably show up in the Tesla parts first before shipping to consumers.
Clock frequencies would be maintained at different levels for each product tier as listed below:
GeForce GM100: 930 MHz Core / 1 GHz Boost
Tesla GM100: 850 MHz (2.61 TFlops DP)
NVIDIA Maxwell GM104:

The NVIDIA GM104 would replace the current GK104 chip which we have come to know and love since the arrival of the GeForce GTX 680.
This chip would feature 5 GPCs with 15 SMX units featuring 3840 Cuda Cores, 240 TMUs, 40 ROPs with a 320-bit interface coming out with 3 GB VRAM (possibly 2.5 GB as done with Fermi) clocked at around 7 GHz for the memory and 1 GHz for the core.
NVIDIA Maxwell GM106:

The GM106 would be replacement for most of the sub $249 Kepler chips such as the GeForce GTX 660 and GeForce GTX 650 Ti / Boost that were based around the GK106 core architecture.
Specifications wise, these chips would see a massive uplift from 960 cores maxed on the current Kepler generation all the way to 2304 ALUs on the GM106 parts. These would be arranged in 3 GPCs which will consist of three GPCs. Like the GM104, the GM106 would feature 4 MB of L3 cache, 144 TMUs, 24 ROPs and a 192-bit interface with 3 GB VRAM operating at 7 GHz clock speed.

NVIDIA Maxwell GM108:
The last chip in the lineup would be the entry level GM108 which is one step behind the GM107 that is not detailed yet but these chips recently appeared in the latest ES drivers which can be seen here.
The current ES sample lists the following specifications - 576 CUDA cores, 48 TMU, 8 ROPs, 64-bit memory controller and a die size similar to GF117.

NVIDIA Project Denver To Appear in Maxwell Refresh?

As for the much awaited Project Denver which is supposed to launch with Maxwell will supposedly be debuted with the Maxwell refresh graphic cards. The user reports that NVIDIA will wait for the new FinFET process that is going to be used to prepare Project Denver and only then fuse them on their Maxwell chips. Their’s some truth regarding this information since NVIDIA showcased their Tegra roadmap at GTC 2013 which showcased their Parker SOC featuring NVIDIA Maxwell and Project Denver CPU inside a die which will be manufactured using the new FinFET process.




The Project Denver CPU utilizes specialized 64-bit ARM Cores which would be fused alongside the GPU die. The specifications for the refreshed part would remain the same and consist of GM110, GM114, GM116 with only the GM110 part getting the full 8 Core Denver CPU. The GM110 part would actually be known as the GM110SOC, the SOC represents a System-On-Chip design. The consumer version of the GM110 with Denver would feature four cores along with the GM114 chip while the GM116 part would only feature two cores. The user mentioned that GM118 wasn’t mentioned with Project Denver so its likely it won’t featuring the new architecture.
Project Denver would feature a coherent link to the L3 cache and will offload the heavy work from the system CPU to the Denver CPU itself. The user also claims that NVIDIA believes Project Denver and driver optimization would give their cards a higher boost than a proprietary API such as AMD’s Mantle would deliver on their GCN products. This is it for the information, you can take this with a grain of salt since much is yet to be confirmed regarding Maxwell but similar reports emerged month’s before Kepler’s launch which turned out to be accurate.
The most important thing we cannot confirm at the moment is whether these chips would be available in 1H of 2014 or not since TSMC is to begin volume production on their 20nm chips in February 2014 and AMD who recently launched their Volcanic Islands series would only tape out their new chips by 1H of 2014 with new products not out until end of 2014 or early 2015. This would mean early 2014 would mostly be the launch of new mobility chips from AMD (Crystal Series) and NVIDIA (Geforce 800M Series) with actual consumer desktop solutions in 2H of 2014.


In 2016, NVIDIA would unveil their next generation Volta graphics card which would eliminate all the bandwidth issues faced with current generation graphic cards by featuring 1 TB/s memory chips stacked on the graphics die. More on that here.

A little more News on Maxwell, looks like Maxwell is starting to Roll out and we might possible start to see more graphics released in the following Weeks.

I just find it strange how quite and reserved Nvidia have been on announcements about this Architecture as if they would rather it not be publicly acknowledged as of yet.

The first cards are mobile chips which are just re-badged 700 series chips, No one has any actual info about the desktop cards plus I doubt they would release the desktop 800 series cards so close to the release date of the GTX 780 Ti unless they want to off all their customers and in the process lose them to another company like AMD.

They should just say the date they are releasing the cards and be done with it, All this rumor crap is like were back in pre-school.

Until an actual date is announced by Nvidia everything anyone posts on here is a made up rumor.

there are some infos about the GM107, but that's not really our market anyways.

TMSC has just gotten 20nm under control but its cost is quite high especially when compared to Intels 14nm(cheaper than TSMCs 20nm). So if these do come out i would expect 20nm GPUs but the cost will be very high.

I would suggest them using Intels fabs(best in the world btw, ahead of the entire world by 2 whole years) and just use 14nm but then i'm just nerd dreaming

Last I saw about Maxwell is that the lower end cards and mobile cards would be coming in around April, and the high end would coming in around November time.

Personally I am not to bothered if they release the 800 series in March/April etc even though I have not long since got the 780Ti's, but there really isn't anything I play that is putting these cards under pressure yet, and my next upgrade will be a higher resolution monitor.
