Tonga has both. Apple got the exclusive use of 384 bit Tonga, aka Tonga XT. The rest of us got stuck with the cut down Tonga, with the 256 bit controller. Even GPU-Z sees the 380 as Tonga.

You guys still don't seem to get what I'm talking about, AMD have done similar before and I finally found one of that articles I saw last year that kind of sparked all this off.

http://www.techpowerup.com/205811/amd-tonga-silicon-features-384-bit-wide-memory-interface.html

This isn't the first time AMD has done something like this. Its "Tahiti LE" chip was essentially a "Tahiti" die placed on a smaller package with pins for just a 256-bit wide memory bus, on the oddball Radeon HD 7870 XT.

Shuffling thing about does not a new chip make, if it walks like a duck, quacks like a duck and tastes like a duck then chances are it's a duck. I still reckon my 380 is a 7950 (with Boost) as too many numbers are the same (including its PPD) for me to see it as anything else.

I once had a duck that tasted like a chicken

The evidence shows that it's a goose, not a duck. Related, but different.

Actually perhaps that analogy is the wrong way around. The goose probably eats a lot more than the duck, whereas Tonga eats a lot less power than Tahiti. Sure, you only get about the same performance, but it's more efficient.

 

[beanoslim]

Its a duck on roids.

:lol:

GPU-Z also read the 7870xt as a Tahiti GPU. The Sapphire 7870XT was Tahiti LE.

If it were anything, but Tonga, GPU-Z would have caught it.

I can see all sides of the duck/goose conundrum.

You know if something ain't broke, don't try and fix it!

On the other hand don't try and palm off the consumer with the NEW tag when its MODIFIED!!

Who knows for sure but from what I can see this IS new tech spawned from the 290/290X and modified.

Similar benchmarks and ppd doesn't mean its the same, just similar capabilities.

That's my 2 penneth anyways.

When the SP, TU and ROPs count is also the same though...

 

[logainofhades]

But transistor count, die size, and asynchronous compute engines amount, are all different. Not to mention the features that Tahiti lacks, that is derived from Hawaii.

So how does it run on the watts/heat side of things??

I seem to look at it like this, lets say it was a car.

Now someone wants to buy an Audi A4 with a 2.0l TDI engine, that's fine..

Someone else buys an Audi A4 S-Line, same A4 badge, same 2.0l engine but its still a different motor?!?

If someone came along and looked at your new A4 S-Line and said oh yeah its just the same as my A4 you wouldn't agree.

So if the 380 IS a 7950 but modified like the S-Line then it IS a different card.

Help me, what the hell am I talking about.......This makes sense right?

I'm thinking more along the lines of the Porsche 911 rip off, lots of alleged "changes" but it looks the same and performs the same as the previous model. :lol:

Well, the power consumption was "broke", to a certain extent, and they did apply a pretty decent fix. And add a few new features, like support for Freesync and more of the DirectX 12 feature set.

I don't see a problem in them calling the R9 285 new, compared to the earlier Tahiti cards. Calling the 380 new, compared to the Tahiti cards, same thing. Of course, the rebranding from 285 to 380 is disappointing. I don't like rebrands.

But I do have to say, that's far from the worst rebrand.

The worst current rebrands I can think of are... first the R7 370, which is a 7850/265 rebrand. A rebranded rebrand. And it's weaker than its namesake in the previous generation, the 270. Oh, and it's the only 300 series card without support for Freesync and the newer DirectX 12 features. It was bad at release, and now that Nvidia has released the GTX 950...

The other bad one is the GT 730. It's a low-end card, where shenanigans are typically worse. But this one's really ugly. There are three different GT 730s. One of them is based on Fermi. Yep, Fermi. It is, in fact, a rebranded GT 430. And a straight rebrand here - no tweaking of the silicon. The "nice" thing is the 700 series branding, and the confusion with the different versions, allows dishonest vendors like Newegg to scam people into thinking they're at least getting the Kepler feature set.

The first sentence of this post says it all IMO. :lol:

I got R9 380 from my warranty company for defected radeon 7950

http://www.tomshardware.co.uk/answers/id-2778632/powercolor-pcs-380-temp-stuttering.html

They can change the name, fiddle with the specs but it's still a 7950! :lol:

 

[logainofhades]

Probably because they no longer make the 7950, and they just gave them something of comparable performance. This is not something unheard of. Item dies under warranty, company does not have same item in stock, gives customer a comparable item. It is not a 7950. No matter how you wish it to be, it just is not.

Yes it is, a few tweaks perhaps but it's the same card. :lol: If it were Nvidia the forums would be lit up in the same way they were when the 8800GT became the 9800GT I reckon except this time it's "Rebadging Evolved" rather than "The Way It's Meant To Be Rebadged". 😀:

 

[king smp]

how is a 670 for folding nowadays?

 

[Mousemonkey]

It should be a bit better than the 660Ti but how much better I couldn't tell you. The 660Ti seems to max out at around 75k PPD by the way.

 

[king smp]

well hopefully once the summer ends i will put my PHII x 6 1100T and 670 online and see how they do
i am hoping to get yo get close to a 100k PPD

No it is not the same card, no matter how much you wish it to be.

That's just it though. I do wish it was something new but the sad fact remains that the rebranded 7950 is a rebranded 7950.

So with your logic a Chevy 400 would be the same as a Ford 400. Or maybe the Ford 360 vs the Dodge 360. Or the little known Chevy 302 vs the Ford 302. My Bronco's motor is technically 408 cubic inch, due to the overbore, and my neighbor's cuda has a 408 stroker. The cubic inches are the same, so the motors are the same?

No, by my logic I'm suspicious about a GPU and last time I checked those were not on any GPU list.
