And the Cypress shader count is...

Charlie Demerjian proceed with caution.

WHEN WE HEARD the specs of Evergreen, the scene was one of jaws hanging down and people almost falling backwards into the snowy ground. The only question at that point was, could TSMC make them on the 40nm process?

The real question that everyone is speculating about is the shader count. It is 1600 for Cypress, 800 for Juniper, going down from there. If clocks stay at their targets, more or less where the current R770 is, that should put the DX11 Cypress right on top of the GTX295 for a rumored $100 or so lower price, plus all the added features.

The GTX285 will almost assuredly get creamed by the cheaper low end Cypress/5850, and the pain waterfalls down the stack from there. The 180mm^2 or so Juniper will basically equal the 4870's performance for far lower cost to AMD, putting pressure on the low end GT200b parts and really hurting whatever Nvidia renames the G92 to this week.

Memory is also interesting, with Evergreen parts using up to 1.25/2.5/5GHz GDDR5. Contrary to many rumors, the upcoming GDDR5+ won't debut until the next generation cards. That means the 1/2/4ish GHz RAM chips used on the 4870/4890 are no longer top bin, nor do they command top bin pricing. AMD will be able to launch 'cheap' Evergreens with GDDR5, halving pin count over GDDR3, lessening PCB layer count and the attendant cost and defect rate. Compare and contrast this to the Nvidia roadmap.

If AMD follows it's usual form, we will see the main two cards, 5870 and 5850, coming out together, or one shortly after the other. AMD will comfortably have the lead until the GT300 appears, if it can be made.

Should Nvidia be able to top Cypress, Hemlock is in the wings to stuff Nvidia back into a hole. Nvidia is unlikely to be able to yield enough parts to make anything more than press samples for a dual GT300 board.

So in the end, depending on TSMC bins and the alignment of Saturn and Pluto in late September, we should see the best Nvidia has relegated to the mid-tier, $125 and under parts bin. Considering it sells GTX285 kits for that much, it's going to be very hard for Nvidia to make money in Q4 and Q1/2010. Like we have been saying, Q3 is ugly, but Q4 looks like it'll be far worse if you are wearing green in Santa Clara.S|A

Monster if true.

On that note, I'm going to bed :o
 
If 1600 shaders, then it truly is a beast, giving the doubling in theoretical performance some people in this forum were hoping for.

Sweet dreams.
 
It gives more power out than a 4870X2 but then with non of the scaling to worry about with those specs, if true this card is going to be scary fast.
 
Im looking forward to ati's new offerings, i was contemplating going to sli when i get my i7 system going (adding a secong gtx 280) but theese new ati offerings sound good so far, thankfully i chose a board that does both xfire and sli.

Given the core and ram are rumoured to be faster and it has allegedly more rops and tmus it should be theoretically quite a bit more than double the 4870 performance*.

God I hope this is true :D


*under ideal conditions

if the 5850 is going to compare with a 285 then how can a 5870 be as good as a 295? doesn't make sense to me as 4850 to 4870 is what about 20% faster?.

Uh, in the article he says the 285 will 'get creamed' by the 5850, not that it'll merely compare to it. I mean if we assume the 5850 is clocked at a modest 700MHz (compared to the rumoured 900MHz of the 5870 part) then the theoretical specifications of the 5850 overtake the GTX285 in almost every area (something even the 4890 clocked to 1GHz fails to do, which as we should know by now, beats a stock GTX285)

That said, whoo, 1600 shaders. That kicks some serious bum compared to this generation of cards. Boo, I can't afford one. Never mind, I think my 4870 will tide me over for the next couple of years either way.
 
God damn it, I need to buy a motorbike I CANT AFFORD TO SPEND £600 ON GRAPHICS CARDS!

But I know I will because I am a moron.
 
dang, looks like my 3890 that is somewhere in a white van on route to me, will be relegated to the spare machine faster than you can say 'holy cow batman, 1600 shaders!'
 
Well this is what I have been biding my time, waiting for, I've had little to no reason to upgrade my 8800GT to date, but after not far off 2 years of sterling service and nothing I have wanted to play that could challenge it, the moment is approaching when I shall call time, from everything I have read the 5850 seems like a fitting replacement, weather it is indeed noticeably faster than a GTX285 or not it's going to be a heck of an upgrade to me.

Even now though, in the games I tend to play (older ones mostly) the 8800GT only struggles at all when I really pile on the AA.
Besides I just feel like upgrading now :D

I'd quite like to get myself a joystick and a copy of MS Flight Sim X ...I've been eyeing it up for some time now, I suspect that playing that with every detail setting set to maximum would push my faithful old 8800GT over the edge, I could be wrong though, I haven't tried it yet. I wouldn't mind having a go at H.A.W.X either while I'm at it.
