Default More leaked slides of the 3850 from AMD!

AMD's 55nm GPUs lead price offensive

AMD's Spider Webbed HD 3850, 3870, 3870 X2 pricing

By Theo Valich: Wednesday, 14 November 2007, 2:16 PM



IN THIS PART, we are able to show you some slides, since they have now been leaked via Chilean hardware site MadBoxPC, so they're out in the public domain.
We have already published quite a lot of information about the Radeon HD 3800 and all the products spawned not from Hector, but from a small chip called RV670.
For starters, differences between R600 and RV670 are very small, you can imagine RV670 being a fixed R600 design. This may be true, but there are still some things that may hold AMD back.

Leaked Slide 1
shows why it is cheap to make RV670 GPU.
First, the good news: HD3800 series is cheap to produce. The 55nm process resulted in a really small die. Official die size is 192mm2, with 666 million transistors, less than double from R600 (700M trannies, 408mm2), and much smaller than Nvidia's G80 (680M trannies, 480mm2) and G92 (734M, mm2, 315mm2).
Whatever happens, AMD stands to make more money from RV670 than Nvidia with G92, unless the 55nm yields are so poor, it all falls into water. All in all, 8800GT vs. 3850/70 = 315mm2 vs. 192mm2.
The decond good thing is the fact that it has 320 superscalar units supporting double-precision, a vast GPGPU improvement when compared to previous the generation and to Nvidia's G80 and G92 marchitectures.
For GPGPU, the RV670 now has an advantage over Nvidia, because G92 units can only do double-precision by effectively halving the amount of data the chip can handle. This will change with G100, but that one is still some time away.
Feature-wise, AMD will brag about real-time Global Illumination, and new Anti-Aliasing modes, all courtesy of DirectX 10.1, which should arrive in H1'08 - at least according to AMD slideware.
The full UVD engine is here too. Daamit is touting perfect HD HQV score, but we'll leave you to figure how close AMD is to the truth here.
It appears the RV670, 3870 will struggle against Nvidia's 8800GT in a lot of tests where RV670 will be texture bound. ATI did not listen to calls or programmers of texture intense engines such as the Unreal Engine 3 and left the same texture management as in the original R600. With over 110 titles in development that use UE3, this could prove to be Achilles heel.
Pricing - or how AMD's comeback is sparking a price war
XFX is coming to market with a very affordable product based on 8800GT. Originally, 8800GT 256MB memory was positioned at €/$200 pricing bracket, now it's down into 150 range (plus VAT).
The reason for such a move is very simple, AMD is back, and it has to be competitive. AMD's pricing for HD3800 parts is really aggressive. AMD did a lot of last minute price reshuffling, because of the performance deficit when compared to Nvidia's 8800GT.
The Radeon HD 3850 256MB GDDR3 PCIe will come to market at, just 150-160 EUR/USD plus VAT. This board is targeted to turn the 2600XT/8600GTS market upside down.
The Radeon HD 3850 512MB GDDR3 is not technically AMD's first choice, but partners are bringing this part to market because they fear a poor market reaction to the 3870 and dual-slot cooling. The 3850 512MB will be your 180 EUR/USD part, cost marginally more and will not be promoted by AMD. 3870 512MB GDDR4, is set at a price of 200 to 210 EUR. All prices are without VAT.
AGP owners will be happy to know that they were not abandoned by AMD. Radeon HD 3850 is coming to market in AGP form as well, but not much has been defined. It is a 180 EUR/USD part if 256MB GDDR3 memory is used, or a $200 part if 512MB is used, depending on partner. Sadly, due to cock-up named “Catalyst driver”, we're not sure if you're going to see this part coming to market before January 2008.

Centre of controversy - why this chip isn't clocked higher?

On that subject, it will be interesting to see how Nvidia and AMD products fare in summertime, when temperatures jump high. If a large number of boards go awry, we'll know who over-stretched the thermal budget.
We disclosed some elementary details over Radeon HD 3870 X2 last week. The price of this board, will be set between 400 and 500 EUR/USD. You've read it right, 500 whatevers for 1GB of local memory, two RV670 chips, all running at a clock of single-board 3870. The product should be ready by February, and late January or early February are your launch dates.
This is an extremely aggressive move, and dual-PCB G92 will have to follow this aggressive pricing - no repeat of the 8800Ultra that was priced beyond belief, yet offered so little.
All in all, Daamit has aggressive line-up. Where it cannot compete on performance or gets passed by Nvidia engineering, the execs raise their hands in the air and start talking about pricing.
the 3850 512MB should be a really good product, but if AMD touts DirectX 10.1 and UVD like there's no tomorrow instead of talking about best performance and scaling, you'll know something is up. µ

Stocks sagging badly these days- hopefully these hopeful possibilities turn things around- there's rumors right that AMD's President, and newly appointed boadr member Dirk Meyer might be ousting Hector as the CEO in the near future.

I really hope that this impending release helps them, I really do. I don't look forward to an Microsoft/Intel/Nvidia only world...We have enough monopolies as it is.

Hrm seems like people aren't happy entirely over at AMD. That could also be reason enough for investors to become uneasy. Investors don't uncertainty , you cannot forecast it and chart it...Sometimes a shakeup is what the doctor ordered but who knows...rumors are just that rumors...someone once said the Earth was flat.

Qwerty.

Qwerty.
That wasn't a rumor, it was a fact. Just like we know everything now, so did they back then ;)

But really I agree, healthy competition is always a plus for us on many levels; price, technology, choice, preference... I'd like to see AMD holding the reigns for a while w/their CPUs and I'd even not feel bad if the new gfx cards ARE better than my 8800GT.
