AMD Radeon HD 6870 and HD 6850 confirmed to be launched on 22.10.2010

[Manicdan]

I would've called the:

hd6850-hd6820
hd6870-hd6830
hd6950-hd6850
hd6970-hd6870

Then kept the 69xx for x2 gpus only...easer to understand...dont you think?

cant, since all 6800s are suppose to be xfire compatible, if you mix numbers then you are also suppose to mix cards

which then makes my opinion pointless too, lol

people just need to get over the naming thing.

Seems to be a 5 VLIW design. 16x5x14 = 1120 shaders total. Might be mistaken though, and I dont know if there are shaders disabled but it is very unlikely. Id say 6870 should be within 10% of a 5870.

6850 should have some shaders disabled and perform slightly slower than the 460 1GB IMO. Not bad

Improved Tesselation, AA, AF, added features, better Perf/mm^2, Perf/Watt, great overclocking headroom (I know that the 6870 is a great overclocker, but lets just say its a rumour) all add up and are most welcome. Heres hoping they are priced right. $199/$249 should translate to £169/£209 over here, thats great if true. Id get better than 5850 performance for the same money. Small leap, but every little bit helps

edit: Tajoh, 5850 @ 5870 speeds is still about 3 - 5% slower. This is faster than 5850 having 320 less shaders at roughly 5870 speeds. Surely there have been changes to the architecture, but maybe not dramatic..

Since they have added a bunch of hardware features, why wouldnt they tweak the arch while they are at it? As I mentioned a month or so back, Barts is a tweaked Cypress with added features.

I think that extra 50mhz is helping out as well as the extra memory bandwidth quite a bit. The extra shaders are not helping that much because a bottle neck is already being reached I think.

I don't think its's really that much better than a 5850. Your getting less hardware for the money. I think a 5850 overclocked to 900 mhz would beat a 6830 quite handily. If I had the choice to buy both at the same price, I would pick the 5850 as it is more potent because of the performance/clock.

Performance per mm is only benefiting the AMD. The power usage seems similar too between the two cards and I have a feeling game performance is going to more similar than different.

Judging from that review I listed of the 5830(notice the vantage scores too), I think a 5830 at 900/1200clk with double the ROPs would perform exactly like barts xt. Bare minimum I think, doubling the Rops would add 10% to the benchmarks results in that review I posted.

I think the better tessellation performance is entirely from clocks. So if you overclock the 5850 to 900/1200Clks, you would get the same tessellation performance.

So basically the af bug was a hardware problem unlike most people believed and thought it was driver cheats.
thats kinda crazy though?

So Carfax is out of work now, then?

Not really. See AMD's slide, the new tesselation performance depends on the tesselation factor. Previously it was a linear straight line. Surely something has been done to those units to change performance, and also an increase in clocks from 850 to 900 wont net that much of a performance difference (note that 6870 was compared to a 5870 for tesselation)

Youre also forgetting AA and AF improvements, especially the new AA mode which you know is a hardware change.

Also, most voltage tweaked 5850's clock to 1000/1200 and I'd say most voltage tweaked 6870's will reach 1100/1200. Performance difference would be very small IMO, maybe <5%. The added features would make up for it, but again, to each his own.

So yeah, since they did tweak the architecture and i'm sure it has more performance per shader. Not that much more, but there is definitely a change

[hurleybird]

Well actually 6870 is a 5830 with double the ROPs + better ILP + better Tessellator + HDMI 1.4

+ higher clocks, + lower power consumption, + better IQ, + DP1.2, + quad head display support (six head with DP 1.2)

[RaV[666]]

Well ,to be honest, after reading all this "I would call them cards as.." posts, im beginning to see the light with amd chosing.
Taking into account price/performance/features and NOT renaming 5770s ,its clear AMD had a tough nut to crack with naming these, they are to similar to 58xx to call them 5700, 256bit bus for example, different price segment too.
It aint to pretty, but AMD had to do this taking cayman into the equotion.
Price on these looks really good.
And really , all "recommendations" from users here look worse on the whole :P

In this case why not say the 6870 is a 5850 with 320 less shaders (5850 have 32 ROP ) and OC to 900mhz ?

I don't say you are wrong, but right now it's just impossible to say what change or not have been made

You really should get a grip.

First you were yelling about how AMD was only naming the new series this way so they could justify the same price as last gen ( 499 for a 6870 ).

But when that turned out to be wrong you are now saying that they aren't bringing anything new to the table with these new cards, not justifying the price. I'm willing to bet you are wrong about that too. And even if not you basically ignored the better price/performance ratio. What more do you want then better performance for the price?

And why assume the worst? It could be 14 SIMD engines * 20 SPs per SIMD * 4 SPUs per SP. That still comes to 1120 shaders.

like I said, Tajoh is the new Terrance.... nonsense posting with solid facts based on what his imagination fabricates...

HIS 6870 listed @ Tiger for $270 http://www.tigerdirect.com/applicati...926&CatId=3669. Says it has 960 SP too.

Amazon has it for 275 pre order http://www.amazon.com/HIS-Eyefinity-...tag=atmlinr-20. I don't know. Hopefully just prelaunch stunt.

[RPGWiZaRD]

So weren't those slides official AMD slides from a recent meeting then or should we just assume TD is using incorrect data (960 SPs) ? Can't believe we're few days away and yet we don't even know the final specs for sure ARRGGHHH. Must be a new record.

[OCX600RR]

Man I don't think I've ever been this excited about some new cards coming out...ok maybe when the 8800GT did! But boy, its crazy to think we're so close to release date and barely any official specs! Anyway, I really hope they price the 6870 around $250 USD, in which case I will buy one. The 6850 cooler (under the plastic cover) looks VERY tiny...hope they don't run too hot as im sure this would be a turn-off. Really wished the power connectors on the 6870 were placed on the back of the PCB like the 6850!

TD probably transposed the shader count from 6850 on the 6870. The slides say 6850 has 960 shaders.

It looks like is going to be:

6850 = $199
6870 = $249

I think it will still come true. I believe cayman xt will be 499 or higher.

Point to where I really said bart xt was going to be 499. Really show it to me? I said barts was going to be around 250 dollars or more and I am pretty right on that I think.

The only time if I ever did call a 6870 499, is before the damn reshifting of product happened. Really show me where I posted a 6870 for 499(I think cayman is going to be 499 or more) and I was referring to barts? If I said it, you could tell I was posting entirely about cayman being this price.

Really show me!!!! Where I said barts XT was going to be $499.

[informal]

CFing two 6850s (or 6870) looks to be great choice from perf/$ POV. If 6850 OCs good,it may become the new 4850 and instant best buy.

No problem:

But its going to be pretty scary for the consumer. 6870, 499 MSRP 600+street price. 6970 750MSRP 850+ dollar street price.

We already knew about the renaming, as is clear by your reference to the 6970 and in the context of the thread up to that point.

This was August, nothing was confirmed about the renaming.




I was referring to this chart obviously. Hell I quoted it, which suggest Cayman as a 5870 series. Not bart xt or this new 5870, as your trying to make it out to be and completely misconstrue.

"Is that referring to performance or pricing. Because it is pricing which is likely, its looks like everything getting priced to what I suspected it would. A 6770 being priced like a 5830... ouch. I think the 6650 and 6670 have to stay at the pricing they are at because they still have to keep some cards under 100 dollars. Man though, if the 6970 gets priced at 699 or 799. The 6950 is priced like a 5970 and those cards are already 700 dollars. Man thats going to suck for the consumer. Makes me scared how pricey the black editions or limited editions will get. Want to replace the 4870x2 but man its going to be pricey.

If it is in regards to performance which is less likely, I think its pretty underwhelming to see the 6850 slower than a 5870.

It wouldn't surprise both are true and performance is as the chart shows as well as pricing is going up for almost the entire line up."

I said that chart referred to pricing, so bart xt for example or the original 6770 would be priced at 5830 levels and 5830 levels is 239, some rumors are suggesting this type of pricing and these are on the lower sides of real estimates? What really damn you in this argument is that chart, if this is your only evidence is the cayman name is right where the 6870 is.

Your honestly not making a case for yourself here. I wasn't stating anything as facts and I was interpreting a chart which you can tell by the tone of what I was writing.

[kuroikenshi]

mate your logic is a flawed as your posts, from the majority of your posts I have read for the last few weeks, you seem to arrive at conclusions by pulling them out of your hat, if you post something just to do thread bashing then so be it.... you asked where you said about pricing, it was shown to you and now you give a piss weak excuse..... really depicts poor personal character as you try to avoid admittance for your mistakes
