[guru3d rumor] GTX 880- 8GB-3200 SP's

[Fastx]

Just rumor but sill very interesting to see some possible info on the Maxwell GTX 880.

Interesting info appeared on the mighty intrwebzz today as apparently an engineering sample (ES) of the GeForce GTX 880 was intercepted on its way from a factory in China which was inbound for a dev center in India, we kid you not. The story gets even better as apparently the shipping manifest of the package was obtained by Chinese press.

That manifest mentions "GM204" and "8 GB GDDR5,". And yeah, that is also the most important stuff found on the manifest The Nvidia Maxwell based GM204 will be the followup of the GK104.

The GPU will get 3200 shader processors if we can believe the rumors that is. 8 GB on the card seems rather excessive though, perhaps an engineering sample that later on will end up as a 4GB SKU.

The leaked specs will see the DirectX 12-capable GPU feature a streaming multiprocessor Maxwell, or SMM, SIMD design that is found in the also Maxwell-based GeForce GTX 750 Ti. The GeForce GTX 880 will just feature more of those SMMs, spread across multiple graphics processing clusters (GPCs) and see some extra performance when compared against the GTX 780 Ti. We should expect something along the lines of these specs
•GM204 silicon
•7.9 billion transistors
•3,200 CUDA cores
•200 TMUs
•32 ROPs
•5.7 TFLOP/s single-precision floating-point throughput
•256-bit wide GDDR5 memory interface
•4 or 8 GB standard memory amount
•238 GB/s memory bandwidth
•Clock speeds of 900 MHz core, 950 MHz GPU Boost, 7.40 GHz memory
•230W board power

So we have a rumored 3200 CUDA cores versus 2880 on the GTX 780 Ti. Base clocks increased from 875MHz and 928MHz for the Base Clock and Boost Clocks, respectively on the GTX 780 Ti, to 900MHz and 950MHz on the GTX 880. Interesting is that the manifest mentions 47,000 Indian Rupees which converts to a value of US $780, well .. here's that manifest, courtesy to Chiphell.

No.
Numbers don't add up.

Didn't we have one of these manifests posted a couple of weeks agp also?

So, what's a "water cooled plunger"? Especially since it's ~$3500

It looks like there are water cooling components on the manifest as well, but the pricing seems off. Interesting, though.

Edit: Sorry. You are right I misread the price of the price of the plunger.

Also, if the chart has the prices right then,

1) The GM204 based flagship is going to be faster than the GK110 780Ti, because they are trying to charge $700 for it.

2) Nvidia assumes that people will stupidly pay the premium for early Maxwell flagship like they did for the 770, & then after 6 months they'll released the proper Big Die or GM210 or whatever.

 

[tviceman]

If this is true, those rop's had better be upgraded from Kepler or this will be a very unbalanced chip.

 

[HurleyBird]

32 ROPs and 256-bit memory look extremely unbalanced to me too. Of course Maxwell is supposed to have a more robust cache, but it still seems off.

 

[djnsmith7]

256-bit memory for a successor to the 780? Step backwards?

 

[DiogoDX]

256-bit memory for a successor to the 780? Step backwards?

GTX580 384bits > GTX680 256bits

You'll have to wait for the refresh to get the top chip as the *80. It's the new order of things.

 

[Saylick]

I agree with the previous posters; there is a huge imbalance between the number of execution units and the ROP/memory bandwidth count. GTX 750 Ti has 5 SMMs (640 shaders) and 16 ROPs. That's a ratio of 40:1 for shaders:ROPs. With 3200 shaders, I'm expecting at least 64 ROPs and not some measly 32. A huge grain of salt should be taken with these specs imo.

 

[Majcric]

I'm expecting the 880 to have 40 rops at the most and Nvidia to drop this thing before the end of the year. The only thing I'm really wondering is where its performance will fit among the GTX780/Ti. On the same node I just can't see much of a gain.

256-bit memory for a successor to the 780? Step backwards?

the ignorance surrounding memory interface needs to die already

remember the GTX280? It has a 512bit memory interface. GTX480/580 had 384 bit interface. GTX680 had a 256bit...

just because we see a decrease in memory interface doesn't mean we're taking a step back, as that's only one pieces to what determines the memory bandwidth

the 512bit GTX280 had GDDR3, so that hurt it, going to GDDR5 allowed the 480/580 surpass that memory bandwidth despite 384bit. Going to much faster GDDR5 allowed the 680 to match the 580's memory bandwidth despite 256bit, and improvements in efficiency meant it could do more with that same raw bandwidth.

Granted, I will admit, going back to 256bit might be a step backwards in performance this time around if rumor is true, but we can't really make any snap judgements until we see a more complete picture of the design, and even then we can't really make and true judgements until we see actual hardware in action

 

[Cookie Monster]

Basically what bunnyfubbles have said. Theres a good chance that the memory controller is completely different with efficient ways of using the bandwidth instead of the brute force method. Same with ROPs, these are not all created the same. Actually perhaps it can be seen with a GK106/107 to GM107 comparison.

 

[blastingcap]

don't believe it

 

[moonbogg]

$700 for the next mid range would be HILARIOUS! God I can't wait.

 

[Fastx]

I am thinking when released the Maxwell GTX 880 (28nm) should be around 10-15% (?) faster than the GTX 780Ti, 4-8GB along with being a DX 12 card. I not sure how this would be considered a midrange 28nm card? This will also drop the the prices on the 780ti after it's released, which btw right now is down to $599.00 on Newegg for the MSI GTX 780Ti.

MSI GTX 780Ti $599.00 ar.

GTX 680 was much faster than GTX 580 with a smaller memory interface and Nvidia charged us for it's performance. You guys need to understand that in the end we're paying for performance and not per die size or 512bit.

If performance turns out to be epic stuff it won't matter one bit, people will pay $700 for it.

That's how it normally works, but prices didn't drop as fast as they normally do. In the past, whenever a new top-end card was released, it generally occupied the price point of the previous high-end card at release. This point point was typically $500-$550.

GTX 480 was released at $500. That's fair. The 7970 was released at $550. That's fair. GTX680 launched at $500. That's fair. GTX 780 launched at $650, which is getting a bit pricey. GTX 780 Ti launched at $700... Notice the trend? GTX 780 prices were only cut once AMD released Hawaii (which, for the record, was launched at $550), and even then GTX 780 Ti was launched at $700. The last time we saw this kind of gouging was when nVidia launched GTX 280 at $650 and they immediately backed down the price as soon as ATI launched the 4870 at $300. I acknowledge that nVidia make good GPUs but I despise their willingness to get greedy if they can get away with it.

With the return of the R9 series pricing back to normal, I don't think Nvidia can get away with such a massive price tag for the 880. I know I won't pay it. $700? Please.

I'm not too sure how much DX12 we'll see in any cards released this year. Msft says that DX12 will have DX11 hardware support. So these companies saying DX12 might not mean much. It could be "DX12 feature set 11.0" for all we know.

BTW the link says $679.99AR. :\

3D it went up since I posted it, I looked at it multiple times it really was $599.00 ar for the MSI GTX 780Ti.

I hope so, but I wouldn't be surprised if they release a GM104 at $550 then release big Maxwell sometime later at $700 without dropping the price of GM104, but I digress...

Realistically, I'm thinking GTX 880 will be faster than GTX 780 Ti at a lower price.

What's that old saying? "You snooze you lose."

What's that old saying? "You snooze you lose."

That is why I looked at it multiple times (nice price) it did make me think about it! But thinking I just can't see paying $150.00 over a 290 Vapor X when over clocked. If we are starting to see this kind of pricing on the MSI 780Ti now at times wonder what the pricing in the not to distance future will be especially with the AMD cards price drops and the GTX 880 on the horizon maybe Q4.
