AMD DX11 RV8xx Card Exposed

[Talonman]

Actually the card is Juniper XT and like I said, should be around 4870/4890 performance at a "nice" price.

We need a best guess listing, to keep the various cards performance straight.

Yah but hes saying equivalent... which would be Cedar.

I agree it's juniper, but thats not the equivalent of the 4850 in the 4xxx series. And yes Juniper (the card pictured) performs like a 4870.

how well does it OC?

heh, got me. I'm just going by Cj's vantage run of P9500 compared to a 48701g of P9800... No idea of the clockspeeds or OC headroom. Probably know for sure in 3 weeks though

[zerazax]

All he's saying is that price wise, it's equivalent to a 47xx type card, but performance wise, expect it to be a 4870-4890 performer

Looks like the leaks are coming in!

[largon]

I'd say the way HD4770 OCs is a good way pointer for other 40nm chips too. They say TSMC 40nm is Black Diamond 2, and 130nm version of it was nice...

More like HD4850 OC or GTS 250.

This sentence was very confusing at first. This is what I was missing:

Black Diamond and Black Diamond II, a low-κ material developed by Applied Materials used in semiconductor manufacturing

[Wh!te Sh4dow]

i'm seriously looking forward for these cards ! my 8800 gts 512 needs to get some rest

[Afterburner]

Just want to share with you guys.

Sounds about right. Thats a few days before Windows 7 goes retail. According to what AMD/ATI had in mind. As for the rest of the lineup:

The Earlier the merrier.....

I wonder if AMD finally fixed their power guzzling, freq-transition-flickering GDDR5 controller. The scary thing is, RV770 had the issue from get-go, and they didn't fix it in RV740, nor in RV790. That's 3 chips in a row with an issue that alone blows the idle power consumption sky high...

Hope they fixed the idle power consumption. Otherwise I'll wait for Nvidia.

I really hope for it too. I understand the high load p.c., but the idle p.c. is madness...

[~CS~]

4890 idle power consumption is lower then GTX260 and lower then 4870 idle and load , they refined the design before putting it on the 40nm .

[largon]

^GTX260 216 idles at ~40W lower than HD4890. All because GDDR5 is not downclocked, resulting in crazy idle current draw for the MEMI/O.

[Xoulz]

While 512 bit buswidth is rather out of question, wouldn't it be so sweet if Cypress was equipped with 384 bit buswidth, if it comes as a 360 mm^2 chip, i think it wouldn't be pad limited. Just imagine, a 360 mm^2 chip with 1920 SPs, 96 TMUs, 36 RBEs on 384 bit buswidth (6 RBEs per 64 bit mem controller) using 1.5 GB of 1.2 GHz GDDR5 chips, greatness !!

I just put that^^ in my pipe and smoked it... I'll have to tell ya, it was very tasty!


I'll take two more please!

[Hell Hound]

1.2 GHZ CORE and 2GB MEM @ 1.2GHZ.

[largon]

^Huh?
Not gonna happen.

Xbit labs show a different story they measure at the card and its somewhat consistent with other reviews i saw .But am not sure who to believe .

[nsegative]

I just changed my idle clocks on the hd4870x2 to 300 core and ram and turned catalyst ai to off to run in single core mode. All good.

[Wh!te Sh4dow]

is that dynamic ? i mean, do you have to enable the "crossfire" again manually + the clocks each time you want to play or not ? if not, sounds like a good deal !

[Sh1tyMcGee]

its getting close to launch and no specs yet, i think this might be a paper launch, lets hope not, cross your fingers.

[bill_d]

Please note that the benchmark results will be known around two weeks after the product launch, in order to give enough time for paper magazines and partners to fill in the stocks world-wide. Just like the Radeon 4800 series, Evergreen hardware will be available world-wide at the same time [this time around, late September - around 24th].

Show me other review that show that? Xbit is the only place with such results.

Along with tech power up, anandtech, hardwarecanucks and guru3d, I think they all show the 48xx with ddr5 eating lots of power during idle.

You could easily see that when downclocking the RAM manually in idle. Yes, the GDDR5 eats a lot of energy while doing barely anything...

So, I sure as hell hope as well that AMD fixes this

You could do that "kind of" automatically with Rivatuner, at elast there you can set different clocks for 2D and 3D Dunno about CF though.

Here's a thread about that (in german), I'm quite sure there's something like that in english forums
