Gentlemen:
I've just been reading thru this thread and I'll quietly ask one thing of all of you;
Stop with the personal insults.
It demeans YOU not the person your insulting.
Thanks for listening.
Doesn't quite add up.

Regarding performance drop, everybody has sins of their own, like 9600 GSO G92 edition vs 9600 GSO G94 edition, LOL.
RV790 is an OCed RV770?
Source:ExpreviewQuote:
Last year AMD got a great turnaround with the help of RV770, but now it seems somewhat weak in front of NVIDIA GT200 Series. After NVIDIA’s partners pushed out their self-designed GeForce GTX260, the launch of GeForce GTX285 and GeForce GTX295 have made NVIDIA even more confident in this battle.
What move will AMD take to fight back? RV790 has aroused interest from lots of people as well as 40nm RV740. According to our source, RV790 will be named as Radeon HD 4970, with core clock improved to 950MHz (compared with 750MHz on HD4870). The memory clock keeps unchanged as 900MHz (i.e.3600MHz GDDR5). Based on 55nm manufacturing process, RV790 will come with 800 stream processors just as RV770, not 960 ones as rumored.
With massive 27% improvement of core clock, RV790 may target at GeForce GTX285. Maybe you would think AMD is confusing us on purpose like what they did to RV770, but the informer believe there won’t be much change in specs. The availability and pricing of RV790 are not disclosed yet, but hardware-info says it would be announced in April........
Is the 950Mhz core clock going to be standard vanilla version or is it the OC version clock speed?
Also will there be a 4890 OC x2 ?!?!
I find the 950 mhz rumor pretty reasonable. Not saying it's true or not, I have no idea, but it sounds fair enough.
I mean, we can presume that ATI planned ahead and knew Nvidia would respin G200 on 55nm, probably long before we'd ever even heard of G200 by my guess.
As such, they'd have been saving "golden" chips, which would likely be more and more common as TSMC gets better and better yields over time. Those "golden" GPU's could fulfill this role rather nice.
But who knows.
950Mhz just sounds ridiculous... most of the 4870's today cannot even reach that speed with 0.1v increase, or even +0.2 volts! That would result in a greater power consumption than a GTX 285 today, which really does make it look kinda bad. And I doubt that it would be able to beat a 285 in any games except for GRID. Heck, it still might not even be able to match up against a GTX 280.
Or it might be that 480SP RV770 all over again.
Ooo they insisted it was true. Meeeeh.
ATi Radeon HD4890 is coming on April 6

Elimize ulaşan bilgilere göre, RV790 GPU'sunun çalışma frekansı 850MHz olacak yani 750MHz'de çalışan RV770 GPU'suna kıyasla 100MHz daha yüksek hızda görev yapacak. Ayrıca Radeon HD 4890 modelinde 1GB GDDR5 bellek kapasitesinin standart olması da bekleniyor yani Radeon HD 4890'un 512MB GDDR5 bellekli modelinin olmaması da ihtimaller dahilinde yer alıyor. 256-bit bellek veri yolu desteğine ve 800x paralel işlemci birimine sahip olacak GPU'nun artan saat çalışma frekansına paralel olarak çalışma geriliminin arttırılmış olabileceği de akıllara gelmiyor değil fakat bu yönde henüz resmi bir açıklama bulunmuyor...........

950MHz would do wonders, since the core is definitely not starved by bandwidth due to GDDR5...
I could bench nearly that high on my current vmodded 4850, but i seriously got big diminishing returns due to the GDDR3 memory choking the core
So is a 4890 HD a single GPU core card? is it more faster/powerful than a 4870X2
Overheard something concerning 1Ghz overclocks.
950 clocks would be plain sick. It would easily beat the GTX280 and probably 285 as well
Wait, that article claimed 850mhz core clocks. What happened to 950? :confused:
Wait... I thought that RV870 was coming out in September? Or, at least that is what the rumor changed to last.
If it is on the 55nmGT process, then I would expect nothing less, personally. I have a *decent* 3870, and it can run stable on water at 920mhz, stock is 775.
One thing that I just noticed, is that though ALL of these rumors, the rumor that it would just be a super-clocked RV770 was the first, IIRC. And now, it seems to be confirmed.
My own Sample of RV 790 is "like 4850" with clocks 850/900 MHz ... better model (like today 4870) with 950/975 MHz could be later, but maybe will never be launched !
Pictures, screenshot of GPU-Z, etc, please??
Otherwise, why do you bother telling us that you have this RV790 in your hands? Are you telling yourself that your "better" volt-modded RV770 is exactly like RV 790, so that it's ok to call it a RV790? :p:
Guess what? I have volt-modded mine to 950MHz, so I believe that it will be launched! I officially call it HD 4890, and it can be confirmed by AMD/ATI. :yepp: :rolleyes::rolleyes::rolleyes::ROTF:
Also, my sample is actually 950/975 MHz like you wish you had, and you're right I cannot get it to 1000MHz. :rofl:
(I rated this thread with 1 star.. wish I could rate it with 0 stars).
OK, this is weird. I'm sure I blocked OBR after his fake claims to have a 4850 around 6 months back
Back when jimmyz showed up with the real deal and OBR was practically ousted for lording his false claims of super secret hardware that
made him 'better' than everyone else (a common behavioural trait of OBR)
So why can I see this fakers posts now? A forum glitch?
I was informed he was banned for the same deal recently, ie claiming superiority to others for having NDA covered hardware and not showing proof.
Whatever, anyone with an ounce of experience with him knows to take his information with more salt than fud and inq combined.
