You can put the 285 behind the 7970 ghz and 280x in several of the games as well. Seems strange to cherry pick when you can see a bigger picture.

Also bear in mind in those TPU benches the 7950 reference clocks were crazy low at 850 mhz before someone picks that out as being behind smile.gif

Curious to see what full Tonga can do in reviews, and how theyre going to price it.

Bioshock is fp16 heavy, it seems. 285 isn't half as bad as some make it sound. It comes with better stream encoding support, tesselation and vsr. I'd prefer to have such an overall well-rounded design.
MSI 380 is also pretty interesting at 1.2 GHz.

The 970 was a great buy on release, no doubt about it, but today it is not worth buying as the 390 is a better card for the same money.

This.

It wasnt bad, it was more meh. A bit like AMDs version of the GTX 960. 1.2 GHz is a decent OC though. I thought Tonga based chips didnt overclock quite so well as Tahiti on average for some reason, maybe not then.

For everyone comparing the 285 to the 280x I never said the 285 would match that. The 280x is clocked at 1050mhz iirc while the 7970 is 945mhz.

The 7970 is the same chip as the 280x but only clocked at 945mhz. The arch gains allowed the 918/965mhz 285 to match the 7970. So the same arch gains applied to the 380x given it's 1070mhz should allow it to post a decent albiet small gain over the 280x.

I expect to see street prices below $220 within 60 days of launch.

It is tonga, GCN 1.2 vs 1.0, 8 ACE vs 2 ACE, better tesselation performance, compression and many more.

Great, argument's now in OCN in regards to whether Tonga XT and Tahiti XT are actually the same, this is eerily reminiscent of WCCFtech comment section where you regularly see arguments that Fiji is just a Hawaii with HBM on it.

Kudos to the participants.

http://www.pcgameshardware.de/AMD-Radeon-Grafikkarte-255597/News/AMD-R9-M295X-Tonga-XT-Benchmarks-Apple-iMac-5K-1140566/
pcgh tested the m295x in Apples iMac a while back and came to the following conclusion:
Quote:
Ultimately, can the R9 M295X So at least classify vague in the performance scale , namely more or less significantly greater than the R9 280X - depending on whether the front-end is used . Of particular interest are likely the current requirements , as calculated by us with 855 MHz is likely to be appreciably lower than those at the Tahiti graphics cards
google translate is gross :x

TL;DR/didn't understand
Full Tonga is noticably faster than a 280X with estimated core clocks of 855MHz (Apple said it would do 3500 GFLOPS)

This would have been a great GPU if it were launched a few months ago, but the 400 series are rumoured to be releasing Q1/Q2 2016 so this better be out soon.
