Has the AMD RX 490 appeared in AOtS benchmarks online?

A 4096 shader part was leaked a while back and I suspect it might be the same GPU in the XBox Scorpio - noticed how the PS4 PRO has the same number of shaders as Polaris 10.

It does but PS4 pro uses 2 of the same cut down 7870s that are in the PS4. Using the polaris 10 was too different, they wanted to guarantee full compatibility, which they do by turning one off in basic ps4 mode. Probably too expensive to use a fully enabled chip too.

... the XBox Scorpio is rumoured to be using a 4096 shader GPU but has GDDR5 or GDDR5X. ...

512bit 8Gbps GDDR5? Would also provide 512GB/s memory bandwidth.... bit of a backwards step though given how hard they pushed to have the first HBM card....

Well the XBox Scorpio is rumoured to be using a 4096 shader GPU but has GDDR5 or GDDR5X. I wonder if Vega 11 has both GDDR5 or GDDR5X and HBM2 compatability??

Would be tough to justify putting that on.

Memory controllers need big pads and a lot of silicon. They wouldn't generate heat if switched off for HBM2 use, but just existing would cost significant money.

The other way around *might* make more sense, if a chip is targeted at GDDR5[X] use so the controllers have to exist, perhaps the microbumps to talk to HBM2 aren't significant. OTOH you would have to MUX the two data paths which sounds expensive when data is that wide. The packaging technologies might be entirely incompatible.

I'm going to guess you choose HBM or GDDR at design time, unless you expect low volumes in two markets to force you to want the savings in mask costs of doing one part when two would be better.

A Polaris 12 and Polaris 10 XT2?? Wasn't there a Tahiti XT2 which had higher clockspeeds for example??

... Wasn't there a Tahiti XT2 which had higher clockspeeds for example??

Yup, 7970 GHz edition. The uplift back then wasn't huge - around 8% - but a similar improvement to a stock RX 480 (RX 485, anyone ) would give a boost clock of around 1350Mhz - plenty to break the 6TFlops barrier.

I'm more interested in the Polaris 12 though, if that source is reliable - presumably that's an Oland replacement for the R[X] 450 and lower. It'd be nice to see a signficant performance jump in the ~ £60 card market but I'm not going to hold my breath (OTOH a 512 shader card would make a lot of sense for dual graphics with Bristol Ridge APUs.... ).

lol i really give a rats ass about all these rumours
Soon we will see the Ryzen cpu released which i sure as hell will buy if a good motherboard is released with at least 2 x m2 pciex4 ssd slots and minimal a couple of the 40 Gbit Thunderbolt ports.
I was truly amazed how well the rx480 ran however i had received a faulty one, and it just was not enough for a real 1440p monitor to run all games in ultra. The replacement card a gainward gtx 1070 phoenix gs is also not really cutting that resolution in all games ... i get often stutters and graphic lagg.
Guess i have to wait till more powerfull cards hit the market which does not cost me another bodypart to sell to get them . I might have to sell at least a kidney to get a titanp x

Because everyone think that its the holy grail
It has it benefits but most people forget the smaller the die is the harder it becomes to cool it properly. Which clearly shows with the current fastest cards even watercooling does not make much difference in most cases to get more speed out of the high end cards. They actually run almost the same clock speeds on air as they do with advanced coolers. I would prefer a water cooled one just because my case is not really a cooling wonder.
Before people say just buy a new case... well i will if you pay for me .
