AMD's Tonga - R9 285 (Specs) and R9 285X (Partial Specs)

[tollingalong]

I am amazed no one broke NDA.

I'm not holding my breath on this one but I'm curious... just not excited.

 

[tviceman]

Then again this product wasn't something hyped as ground breaking.

Usually all mid-range and up products break NDA. 750 TI didn't set the world on fire in performance but it got leaked to hell and back.

I am amazed no one broke NDA.

I'm amazed all the AIBs have successfully stopped the leaks. Technically we should already have pictures of the GPU, a GPUz shot, and a bunch of benchmark results.. one month ago. There must have been extra stern talks to management.

plenty of 285's on videocardz.com but not a single performance benchmark leaked other than the official firestrike score.

AMD does pretty good at stopping leaks. Look at the 295x2. It caught everyone by surprise.

[3DVagabond]

I think things are really muddied because of still being on 28nm. I really don't see how this chip could be Tahiti's replacement. I think this was supposed to be Pitcairn's replacement on 20nm.

wow 4K decode

wow 4K decode

But only h264 not h265

 

[csbin]

But only h264 not h265

nvidia MAXWELL same only h264 not h265 ^_^

 

[TimCh]

nvidia MAXWELL same only h264 not h265 ^_^

True, same as Maxwell.

unigine testing on vanilla 285

 

[NTMBK]

Anyone seen any more news on the 285X yet? I find it strange how they've been so quiet about the memory used... and how they manage to squeeze even more performance out of a 256-bit memory bus... HBM perhaps?

 

[alexruiz]

Reviews should start surfacing any time now

 

[DarkKnightDude]

250 bucks.

[csbin]

Another change for Tonga is that it supports 4K video encoding/decoding, something that even Hawaii doesn't include. By enabling support for 4K h.264 content in fixed function hardware, AMD claims to have as much as a 47% performance advantage over NVIDIA's GeForce GTX 760 using applications like Cyberlink Media Espresso and Arcsoft Media Converter 8.

 

[parvadomus]

The power efficiency gain was well below expectations. Hope they can take the 40% better bandwidth utilization into APUs.

 

[monstercameron]

why amd why? why release a new card that is slower than the old one?

about sums it up http://semiaccurate.com/2014/09/02/amds-new-tonga-aka-r8-285-may-new-tech/

 

[Borealis7]

TPU: http://www.techpowerup.com/reviews/Sapphire/R9_285_Dual-X_OC/

same number of SPs as HD7950, 33% MORE power at load

 

[zebrax2]

So it's more like gcn 1.1.1. Pretty boring launch i must say

Holy crap this is awful. Nvidia is going to have a field day if new Maxwell cards really are coming in the next 4-6 weeks. Nvidia is going to be able scale Maxwell up way better than AMD is scaling GCN right now. Price premiums out the yin-yang.

 

[DarkKnightDude]

250 bucks is nice, but so much for any power usage efficiency.

 

[exar333]

Power efficiency is nice, but throw us a bone on performance (5-10%) AMD. This is not terrible, but a bit puzzling that it is much worse using Mantle vs. 280/280x due to the 2GB RAM. If Mantle is the future, why handicap an ideal card that would benefit from it?

 

[Silverforce11]

Pretty shit.

$250 for barely faster than 7950 performance with MORE power use after 7950s have been out for how long?

Sick joke ain't even funny. I still have my 7950 in another rig, and its got 3gb of ram and can run WD with ultra textures.

Bring on 20nm because this is absurd.

 

[Cloudfire777]

Pretty much a useless chip and nowhere near Maxwell in efficiency.
So much marketing for nothing. What the hell are you doing AMD?
