[Sweclockers] AMD Tonga will have the power consumption of 270X but replace the 280X

[Mondozei]

Not only that, Sweclockers are also saying that the Tonga GPUs are already done. So why isn't AMD selling them now?

Because they are merely waiting for the existing stock to run out.

Also, the other details about Tonga is known, the 256 bit(compared with 384 on Tahiti which it aims to replace) as well as the 7 GHz GGDDR to compensate for this.

In other words, we're close to a release and won't have to wait until Q4 for Tonga. Sweclockers are saying we could see it in August already with September as a backup month. It all depends on the sales on the existing stock now.

 

[Mondozei]

Just for those who don't have the numbers memorised:

270X = 180W TDP
280X = 250W TDP

P.S. It's funny that all these leaks are coming to SweC, but still logical. They've been relying on almost only Taiwanese sources for some time now.
Computex gives them the chance to meet them eye to eye and get more info.


Edit: Silly me, the source of course.

Sounds like it'll be a great card. Unfortunately, if it's done and ready right now, but is being delayed because of current inventory levels, that sounds like yet another AMD mistake.

Die size, final performance, and power numbers will be interesting to examine, when that info is available. And here's an interesting tidbit - if it ends up as fast as a 280x, while consuming the same amount of power as the 270x, it will be way more efficient than Nvidia's GM107 - specifically about 80% more performance for only 40% more power draw. Too good to be true or will it make Nvidia's power efficiency push look embarrassing?

This is the same AMD/ATi that claimed with a straight face that the R9 290 was a 200W TDP part at release.

Right, I have a feeling they are speaking "ball park figures." However, if they did go with stacked dram then just how efficient the chip actually ends up being is big question mark. They could have a potentially very efficient part vs. Nvidia's maxwell architecture at the expense of perf/mm^2.

Doubt it, why postpone it if they could sell it at a premium?

 

[f1sherman]

where is mobile Tonga?
mobile wins should already be known by now
or are they launching desktop parts now, and god-knows-when mobile

1) another bad decision or 2) are they really bleeding in dekstop so much that it has priority over highly lucrative mobile

i say 1)

Heh, they did? Ouch. I think Hawaii is officially a 250 watt TDP part. Odd they would claim Hawaii to be less.


From what I can tell, this isn't AMD claiming anything about this part. This is how over-hyping starts.

 

[el etro]

According to TPU graphs is 70w of power consumption reduced for 25% more performance. Competitiveness of Tonga we will know after the launch.

I want see to the effects of HBM on power consumption.

 

[Lepton87]

Somehow this cards looks similar to GTX680 with 7GHz memory to me. GTX770 was clocked as high as it could possibly go reducing efficiency.

 

[ocre]

wow.

cant wait till the next round

Or are we expecting too much for 28nm?

 

[Wall Street]

The power consumption seems right seeing that is about double a r7 260 (128-bit, 95 W) and about half a r9 290x (512-bit, ~325 W).

I just hope that they don't charge as much of a 2 GB -->4 GB premium as NVidia does on the GTX 770.

 

[Bateluer]

They didn't. Hawaii, both the the 290 and 290X are 250W parts in all AMD's specs.

A 290X does not consume 325 watts. That is insane.

Whoops, I meant I thought Tahiti was a 250 watt TDP part. So for AMD to call Hawaii, a higher performing GPU built on the same process with what seems like only a minor revision to GCN 1.1 a 200 watt part, well that didn't add up. So I was hoping he'd have a link... otherwise I have to think he is getting something else mixed up here.

Huh? A GTX680 uses 170W and is nearly as fast as the 280X.

Tonga looks like a GPU comming to the market one year to late. So it will offer ~280X performance with 180W? How will this be competive with any Maxwell GPU/card nVidia will introduce in the same power spot?!

 

[Arkadrel]

Smaller width busses and faster memory always seems like a winning combo when it comes to perf/power & perf/price.

And if most of that power saved comes from just better power phase moduals on the cards... wow.
Why hadnt they done it before?

Looking forwards to seeing this new card thats faster than a 280x but uses less power than a 270x.


Im really looking forwards to 20nm though, and whenever we ll have Hybrid memory cubes, on cards.

Also when will GPUs finally have 3D transistors (FinFETs)? thats bound to be another big jump as well.

Next few generations of GPUs is bound to be fun to watch.

 

[Silverforce11]

Doubt it, why postpone it if they could sell it at a premium?

Because most people who spend at the $300 mark for 280X levels don't really care about efficiency enough that they would pay $350 for it. Same performance, less power. Would you pay $50 extra? Not to mention it would be dangerously close to R290 pricing to make it a poor buy.

Edit: The bad thing is this leak is going to make people think twice about buying 280/X since in a few months they get a new product at that price range with a huge reduction in power.

Nvidia charges a premium for the 750Ti, seems to do quite well. A more efficient card compatible with upcoming variable refresh screens would be worth the premium. I'd gladly pay $50 extra if I were looking for a new card at that performance level.

 

[gamervivek]

That doesn't happen with amd though

 

[tviceman]

Because most people

And there is where you and/or AMD lose the argument. There are still some people who will pay the premium. If the chip/card is ready to go then AMD is absolutely stupid for not releasing it.

Also, unrelated to this particular thought process, other places are suggesting this card will be called r275x, indicating it won't quite have 280x performance.

 

[parvadomus]

Nice, if it consumes the same as 270X that will be like ~50watts less than 770 and still be faster.. it seems Maxwell would be in trouble...

You dont have the sales numbers or stock numbers for 280/X. They do. Putting pressure on the stack when there's heaps of stock left is not cool.

It's not putting pressure if there is a price premium. Economics 101.

Is TDP, man.... Power consumption difference between 280x and 270x is 70W.
