Radeon HD 7000 Revealed: AMD to Mix GCN with VLIW4 & VLIW5 Architectures

[-Boris-]

You'll know everything later tonight.

However, that isn't saying NVIDIA is slacking. If history is any indication, NVIDIA is more than content to let AMD prematurely blow their load with a paper launch and then respond with their own parts a bit further down the road.

If history is an indication nVidia is the one that blows it's load before it's ready, even if it's many months behind. It took all the way to GTX 580 for them to fix GTX 480.

Who said Fermi was broken in the first place?

Plus:

GTX 480 launch: 25 March 2010.
GTX 580 launch: 8 November 2010.

That isn't all that long by modern release standards.

In between those we had products like the GTX 460 which I would argue was one of the best cards of the last two years and was still based on Fermi architecture.

Fermi was fine, albeit a bit hot. I'm rocking a 470 with core and shader to 480 and it works just fine for what I use it for.

Was read a bit the beyond3D forum, and one have see something interesting... 2x 6 Pin = 7950 ?

About the red pcb .. well dont take too much care about it, thoses are AMD cards, surely HIS, MSI, etc will have their own black pcb for the retail cards. ( simply AMD/ATI made by AMD/ATI are always red pcb )

Here is the first clear picture of Radeon HD 7970 engineering sample PCB. The final product will feature an all-black PCB color. The picture reveals the PCB to have provision for two 8-pin PCIe power connectors, though on this sample, there are two 6-pin connectors. We've seen other samples using 8 + 6 pin connector arrangements. Unlike earlier thought, the HD 7900 single-GPU reference board very much does use a digital-PWM power design. There appears to be CPL-made single-phase PWM chokes, and Volterra-made regulators. Not all power domains, though, seem to have digital-PWM. We can find a 5+1+1 phase VRM, with some miscellaneous analog power domains.

The GPU package design is nothing like we've seen from AMD. It looks to be slightly larger than that of AMD Cayman. The die is oriented diagonally, with a sturdy brace around it reduce and stabilize the pressure applied by the cooling assembly. There are twelve memory chips around the GPU, as this chip features a 384-bit wide memory interface, to deliver nearly 50% higher memory bandwidth over the previous generation. The card features redundant BIOS, loaded into two separate EEPROM chips that can be toggled using a small 2-way switch located next to the Crossfire connectors. Display connectors include one DVI, one HDMI, and two mini-DP connectors. The second picture below reveals a curvy back-side of the cooling assembly. A nice aesthetic touch with zero function.

Yes, now I wonder if all the numbers we read around are just about the 7950..

that would take the cake!

lol sounded like he pressed the microphone so close it was touching the 7970...has lots of vibration "feel" to it

leads me to believe its on purpose. or the test cards aren't production units that will be shipping.

[mapel110]

the sound files are made with reference cards from ATI at every launch. ATI selects the cards that are send to the press. I don't believe they send very bad cards to the testers. And Computerbase is one of the biggest hardware-websites in germany with a few million readers.

Stupid marketing people!

[minpayne]

Where the hell are all those sneak peeks? I thought AMD's NDA was always a joke.

[paulbagz]

I don't care about all this stuff, I want to see FPS in games.

lol i want to see it in my newegg cart!

[LightSpeed]

Damn it I want reviews. Got rid of my 6990 and I have nothing atm, 7970 certainly looks good and hopefully it will be within 75% of a 6990 with much less power drawand im happy.

Just the old architekture article from Anand. They pushed it up, probably to generate some more hits...

[Utnorris]

Did you read where it said it was published in June? It was refreshed because tomorrow is the release of the new GPU's.

Haha oops i missed that, sorry... the article states: by Ryan Smith on 12/21/2011 9:38:00 PM

but the user comments are from June !!

The 7970 is a beast! Nice jump from previous generation.

+1!!!

Depends, in the Hardware.info review most games are barely an upgrade from a GTX580. Benchmarks seem to be a rape-fest with it though.

http://nl.hardware.info/reviews/2472...hd-7970-review

slightly faster than 580, but a much louder cooler. doesn't make much sense to me. looks like a dud unless high end video card prices (including 580) get driven down.

[Vipeax]

Some games, like this, give hopes for some driver work. I don't get the noise though, as the power usage is awesome.

[minpayne]

I think the review drivers downloaded from nda.amd.com are still broken for the games. I expect some further improvements of benchmark results. It's less impressive as the HD5870 though.
