Also lets not get too overhyped for any hardware, on both sides.
Only big surprise could be NVidia announcing Apple selected GP106 as GPU for an upcoming product (all we know which product is) they won't say.

Another could be being cheaper than expected,it could mean they fear AMD Polaris and they don't wanna give a chance to AMD to domain mainstream market (and that their insiders at AMD are very good).

If anything is exciting here is the prospect of new Mac Pro. Or trash can Mac Mini with dGPUs, and quad core CPUs. And yes, I am completely serious with typing that. You know, tuxon, why? Because even here people get excited for hardware. Thats why I wanted to cool heads.

Nah, Nvidia does not fear that much, about P10, cause it is different segment. It is like comparing R9 380X to R9 390X ;).

Something important to look for in Nvidia's announcement is what kind of performance increases they can get on 16 nm. They are rumored to be announcing GP104, which should have roughly the same number of transistors as GM200. Can they improve the performance per transistor through either architectural improvements or increased clock frequencies? What kind of power consumption will it have? What will the cost be? Will it have NVLink that would alleviate some of the bandwidth constraints in a mac pro? These sorts of enhancements in generality will likely apply to AMD's Polaris as well.

what;s strange about their announcement is timing. friday evening in US, saturday night in rest of the world. When stock markets are closed. it's usualy a good tiem for bad news.

Guys, please, be realistic. There will be good news.

Yeah, too many people here looking for a conspiracy theory. This is a press conference where Nvidia is going to release the fastest gaming GPU ever. All they have to do is get on stage and show off some demonstration systems playing games/VR. Its on a friday most likely because these things tend to be more like parties so there will probably be lots of food and drinks provided to attendees and press. It also sounds like it is being announced alongside the new battlefield game. Reviews by sites like anandtech won't be out for a couple weeks so we won't know for sure how much better or worse it actually is.

Wow, I don't know where to begin on this one.

Since the MP6,1 running Apple OSX doesn't split load between GPUs (no Crossfire), NVLink (which is a GPU to GPU external connection, not a PCIe feature) would have literally no significance. The MP6,1 has no intra-GPU communication under Apple OSX, so faster intra-GPU links would not help.

Second, the E5-2600 v2 chips support a gob-smacking 78,8 GB/sec of PCIe bandwidth. That's more than enough to do VR cat videos on an epic scale.

Unfortunately,
  • Apple throws half of the bandwidth away by not supporting dual-socket systems. (And also throws away half the memory bandwidth and half the CPU power.)
  • Of the remaining 39.4 GB/sec, Apple gives 4/5 of it to a pair of mid-range Radeons - even though one Radeon is idle most of the time on the majority of non-cat-video rendering systems, and the other one seldom needs more than x4.
  • Only 7.9 GB/sec left to do real work....
The "bandwidth constraints" on the MP6,1 are due to bad design decisions by Apple. Use some PCIe switches that will dynamically allocate bandwidth where it's needed, rather than permanently sending 16 PCIe lanes to a "compute GPU" that is seldom active on most systems.

yeah... as i watching this stream video...i was like...whoa...major improvement vs. titan x. at least that's what they stated.

More power efficient, on top of just being faster, twice the performance of a 980, that's progress. Apple should take a leaf out of their business book on how to make progress.

By the way...the price is at 370-ish...lol.

375$ for 6 TFlops

or 1200$ for a couple of GTX1080 accounting 18TFlops crushing AMD RadeonProduo by 3+ TFlop, 300$ less and just 360W combined (and 16GB DDR5X total)...

Hope for AMD nVidia has something big to fear, elsewhere AMD its doomed to be a 2nd-ish GPU Maker

TFLOPs is indicating great performance. Also it is first, single consumer GPU with that level of performance.

However, I will wait for reviews. Strange, leaked 3dMark was putting the GPU on 1.86 GHz levels, official reference GTX 1080 has 1.733 GHz core clocks. I wonder what will be the end result for that.

Sounds like the AMD PR folks here at MR have seen the light.

Well, they still have a formidable lead in their hand warmer and space heater divisions.

Perhaps asynchronous computuzationally will save the day yet?

During the presentation it was supposedly running at ~2 GHz. Perhaps it was overclocked or can dynamically change the clock rate?

DP 1.4 (non-certified) and HDMI 2.0b for Pascal GTX 1080

AMD chose DP 1.3, so there's a real advantage for Nvidia. The rest is to be seen. Although Nvidia has certified DP 1.2 only, but it is DP1.3/DP1.4 ready. Nvidia's' pricing shows that they believe AMD is going to have awesome products too.

Nvidia promoted, that they have advanced in perf/power, but didn't tell how much. Also we don't know about the double precision figures for Nvidia. But it shouldn't be difficult to beat current Fury fleet on that area.

Fury Nano = 8192GFLOPS single precision with 175W TDP, prices varies ~$499
GTX 1080 = ~9000GFLOPS single precision with 180W TDP, MSRP: $599

Nvidia promoted that games can go 3x.. and it is reasonable claim, if you think, that they were not doing great on DX12. But still, this was a paper launch and the lack of clarity about specs, pricing and availability are never encouraging.

http://www.anandtech.com/show/10304/nvidia-announces-the-geforce-gtx-1080-1070

And mr.BullyVidCard and others, please, we are on macrumors. We are talking about Mac's and guessing where Apple is heading. Apple has chosen AMD three year ago. We've tried to understand why. And on the way to enlightenment we've learned a lot of their technology. Will Nvidia make a return.. who knows (not you I suppose).

And before we call it a game lets see AMD's cards and Nvidia in a real use. It's nice that these GTX 10xx models are available so soon.

UPDATE: GTX 1080 is told to be around 5-10% more power efficient than GTX 980...
