    So then Polaris is a new GCN based architecture?

    Guessing much of that power savings is due to the 14mm lithography. Once nVidia shrinks their dies and gets HBM2, they will also have substantial power savings. Hilbert, I do appreciate you calling out the apples to oranges comparison they did to the nVidia 950... "our 2016 models are better than the competitions 2015 models (which aren't substantially changed from the 2014 models)!" I should hope so!

    Yeah it would seem that way. Which is honestly good -- AMD doesn't need to waste it's resources redesigning an architecture. GCN is fine. It just needed to bring power consumption down. 14/16nm will obviously help that but the architecture itself needs to bring improvements as well if they want to compete with Nvidia, which I'm sure RTG is doing with Polaris.

    I find it really weird that they are dual-sourcing parts out of GF/TSMC. I wonder if 14nm will be restricted to APU stuff. It seems weird that they would have pay the overhead of dual sourcing in their main GPU line.

    I agree. Hell, GCN is good enough that AMD is still rebranding GCN 1.0 GPUs (even though nobody seems to really like it when they do that).

    As long as both AMD and Nvidia can't figure out how to get decent FPS for 4k screens, working on power efficiency is the next best thing. Both companies have GPUs that are more than good enough for 1080p and sufficient for 2k, so as long as they keep that performance while lowering the watts, I'm happy.

    So basically we will see 5% increase in FPS and some % lower TDP, is all I'm getting out of this.

    tdp is not the overall system power consumption

    And I am talking about the AMD part power consumption.
    I believe for now the only hope for performance improvements are dual GPU cards and DX12/Vulcan.

    And getting murdered, is what you forgot to mention

    Having to use big-small Tonga die and feature-less Pitcairns to fight mid-sized GM206 - is anything but GOOD ENOUGH
    But it's actually good compared to the state of AMD high-end GPU market share.

    that was the overall system power consumption that was given

    The purpose of this demonstration for RTG was threefold: to showcase that a Polaris GPU was up and running, that the small Polaris GPU in question could offer performance comparable to GTX 950, and finally to show off the energy efficiency advantage of the small Polaris GPU over current 28nm GPUs. To that end RTG also plugged each system into a power meter to measure the total system power at the wall. In the live press demonstration we saw the Polaris system average 88.1W while the GTX 950 system averaged 150W. Meanwhile in RTG’s own official lab tests (and used in the slide above) they measured 86W and 140W respectively.

    i really would like for people to start to read the info first post second

    People buy more quadros than 370/380's? Anyone else thinks this is strange?

    except that it wasn't

    says:
    "Polaris card on med 1080p scored 60fps and consumed 86W"

    4790k rig is around 60-ish watts in idle
    86W while gaming rly?

    did you even read the post i have given you, here it is again

    The purpose of this demonstration for RTG was threefold: to showcase that a Polaris GPU was up and running, that the small Polaris GPU in question could offer performance comparable to GTX 950, and finally to show off the energy efficiency advantage of the small Polaris GPU over current 28nm GPUs.

    I did now. And it sounds very impressive.

    OTOH 86W at the wall.....thats like 70W real consumption. Which means card + CPU are pulling 10-20W watts above idle.
    I'd like to be wrong, but I think someone there needs to retake their electronics lab class :D

    edit: on a 2nd thought, it is a double node jump. so it's quite possible :banana:

    yeye we covered that already. Looks like Polaris is around 30W

    For GTX 950:
    140W - 90W(ingame) = 50W (idle)

    Polaris:
    85W - 50W(idle) = 35W (Polaris+CPU)
