Do you believe your source?
This means better than Maxwell efficiency. If true, an amazing achievement.

This is also only the 370X. I can see why the clearing of inventory was important.

I will wait to see the reviews. This is a lot to accept.

That would make it as fast as the 290, with Maxwell-level efficiency. Impossible.

His 40% faster than 290x and 15% above GTX980 is from latest computerbase benchmark(1 day old 17 games)
They ADD new games and radeons sucks there.
Btw whole news if you are interest

If you look at the methodology article the 290X they use is likely using a reference cooler and is throttling badly. The 290X OC number is much more representitive of anyone with an aftermarket card, even one at stock speeds, than the non-OC number.

Are you so sure about that?
Look at my post again and what the card contains. Look what cards im referencing to. R9 285. Thats not the only Tonga is it? Think about the different manucaturing processes we have talked about earlier.

What do you get?

Here is a help

I think he knows very much. I have price and everything. But for now the previous post is all I have been given permission to post.

If those specs are correct then it could go some way to explaining the delays. Getting HBM into products that far down the stack would surely put a strain on the supply chain.

Also with good binning and appropriate clocks/volts that would make a nice high-end notebook chip.

So HBM and 20nm? That's the only way I can see such a drastic power reduction.

The million $ question. How is this possible?
It will be interesting to see who spins a negative from this, if true.

While what you are saying is a possibility, why can't AMD improve efficiency some other way? It could be a chip engineered very specifically for gaming like Maxwell. They could be using power gating. They are supposed to be working very aggressively on power gating for their APU's. It's not like they've never been able to design an efficient gaming chip. They were doing it before nVidia.

If you're going to continue the personal attacks, I'm not going to bother with warnings and infractions -- you're going to be getting time off. Get the chip off of your shoulder, NOW.

Isn't maxwell's power supposed to rise disproportionately when all of it's resources are being taxed, suggesting some sort of power gating in place.

Well, a 285X would be approx 15% faster. Could you get an extra 10% from HBM? I suppose. The TDP of the 285 is 190, so 20 nm and HBM cutting it down to 140 isn't crazy. I question AMD being able to sell it with HBM at like $200 though.

So, were looking at a GPU with between 2048-2560 GCN cores, with HBM memory.

If I would be asked, 3072 GCN core GPU would be around 180-200W of TDP.

For me its a bomb.

I'm not saying it's not possible, it just seems less likely that they went from 250-300W of power usage at the same level of performance to 170W on the same node.

Plus cards like the MSI 970 and gaming Colorful 970 have much higher maximum power usage, so it's not just purely hardware efficiency.

It turns out that, if this is true, you will be able to play Blizzard games in 4K on 370X...


Quite impressive.

Harvested die? Seems strange having HBM down that low in the food chain.

390x must be beastly.

0 to 100%, how reliable is that contact of yours? would you stake your rep on this leak? cause if 370x is this fast. damn.

 

[SimianR]

370X at 780 performance isn't really that insane. If the power usage is accurate though, that's pretty impressive.

 

[JDG1980]

I honestly think we've reached a point where financial discussions on AMD/NV/Intel should be in a separate sub-forum, not a part of a technical/specification speculation thread of specific products.

Count me in as a second vote for this proposal. We don't need to have the same discussions about financials in every thread.

 

[maddie]

You do realize that the 370X is most likely the GTX 960 competition. Would you consider a 960 as fast as a 780 to be insane?

Seriously. It's always the same few posters, "Look at my R&D and/or marketshare and/or quarterly earnings charts, they provide an extra 7 fps at 640x480x16 !!1!1".

Irrelevant! They just want this thread locked as usual, and they're almost there.

 

[Nachtmaer]

If that 370X rumor is true, then it makes those old rumors of Fiji actually being called 380X instead of 390X a lot more reasonable than I originally thought. It wouldn't seem likely to me that if a x70 tier card is that fast both 380X and 390X will be single GPU cards, unless they use one chip for two tiers. Maybe it also falls in line with the rumored AIO cooler for the 390X because it might be a dual GPU card. I could be totally wrong though.

Edit: giving it more thought, this would leave a huge gap between the 370X and whatever Fiji will be.

These speculations on top of speculations are starting to get out of hand.

Hmm. Sounds ludicrous at first glance, but I suppose it's possible. R9 285 has 1792 shaders, while we know that the full chip has 2048. That's a 14% increase in shader power just by not cutting down the part. So you need about another 10% boost on top of that. Architectural tweaks plus the move to HBM could probably get you that far.

That said, TechPowerUp has the GTX 780 pegged as somewhere from 27%-32% faster than R9 285 (depending on resolution), not 25%.

The full Tonga in the Retina iMac has a maximum TDP of about 125W - though there have been complaints of throttling. Do some more tinkering around the edges and port it over to GloFo 28nm SHP (assuming that process is indeed more efficient for GPUs, as has been rumored), cut out the power-hungry GDDR5 memory and controller, and implement better binning... sure, 140W seems doable under those circumstances. What makes me skeptical about this is that the most plausible existing leak on the R9 370 indicates that it has GDDR5, not HBM. (Source). Then again, it didn't launch in April like the source claimed...

I think we would all be guessing at this point - but to me it would make more sense for the 370X to be lined up with the 970, the 380 competing with the 980 and the 390X somewhere between the 980 and the Titan X. Who knows how it all actually ends up playing out though.
