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

[LightSpeed]

You deserved it, 400+ posts in a thread and you drop a line as welcome as a fart in a elevator.

On a serious note, I really hope the 6870 at least matches the 5870. I actually think it will, but lets wait and see, reviews should be out next week hopefully

According to the Chief Editor at SWECLOCKERS.COM review will be up Friday am CET.

NDA on pictures and specs ends tomorrow morning CET.

The numbers for GTX 460 768MB and 1GB are very wrong....

did you play game, gtx460 768 MB has 40fps Japan level 1920x1200 16x/4x and 42.3 London level, results depend on testing levels

[Maxforces]

90% of the Dirt 2 numbers I have seen in reviews seem to be incorrect due to the use of the early stand-alone Dirt 2 benchmark, improper implementation of forced DX11 or using an old version of the game engine (patches have increased performance quite a bit).

and 90% don`t change car name settings that were the same cars in benchmark.
Anyway GPU Benchmarking Process hardwarecanucks sacks big way,BC2 incorrect, AVP incorrect,FC2 incorrect (benchmark),JC2 incorrect,Metro incorrect, this way never will have 100% repeatable test

and this is why I usually only take reviews from you guys, hard and anand as anything with serious weight.

¿First leaked benchmark?
Dirt 2 DX11

Around the rumored 20%~ advantage for 6870 over 460 1GB.


Battleforge SLI vs CF

¿First leaked benchmark?

Posted about three times I think and quoted loads of times.

Seems like some of the new cards should be using 4 VLIW structure according to guys at Beyond3d.

It means that there is one member of a future GPU line from AMD which has indeed 4 slot VLIW units.

Why do i suspect that these new "renamed" parts will be much competitive to its older, replaced brothers in real games than in 3DMark bench ? In 3DMark bench the old card shines for their abundant of raw shader power, but i sense this new gen chips employ better efficiency that free many bottlenecks in older gen chips to achieve better real world gaming performance.

A little more info and some nice pics.

Still no decent benchmarks or pricing though...

If I'm buying, I'm buying the card that has no manufacturer's sticker on top.



Don't screw this beauty up, manufacturers.

[kuroikenshi]

WOW!!! what a tool for graphics designers, no more "painting rocks" this is one of the reasons Physx is most likely going to go out of use, not opened source outdated code

You can always peel the sticker off.

[Mechanical Man]

So what about those B3D rumours, that Cayman would be 4 VLIW and Barts 5 VLIW? How that would affect performance.

Physics and tessellation are separate technologies, and not mutually exclusive. Tessellation doesn't alleviate the need for a physics library.

GPU accelerated Bullet physics (open source) is what they are using in that demo, according to the slides.

Quite a bit. If barts has 5 way shaders, that means it has 224 shaders(which is a weird number). How much of a tweak can they get out of a 5 shader architecture to directx 11? 5 shaders sounds alot more like cypress.

What is true? The 5 shader thing is also being mentioned in fudzilla for barts? I hope Fud can atleast get it right 3 days before launch.

If cayman has 4 way shaders and 1920 shaders, it would have 480 real shaders.

[generics_user]

aww 6850 has thecraptacular blower form the 5770 series...

at least 6870 kept the 4870/90 5850/70 5970 model which is inaudible @idle

Why do they compare it to the 5850 in one, then the 5870 in another image?

[zalbard]

Looks very nice. Improved AA, up to 2 tessellation perf. using a smaller chip (imagine Cayman)!

[SimBy]

Barts SEP:

6850 Barts Pro $179
6870 Barts XT $239

[marten_larsson]

Why do they compare it to the 5850 in one, then the 5870 in another image?

Probably cos it sounds better if they beat the 5870 in tessellation. However, from what I know, the tessellation is the same in 5770 as 5870 so...

[Metroid]

So the 6xxx series are supposed to be 35% cheaper. Is this going to happen?

[zerazax]

Interesting, so they really went for 14 SIMD's? Weird, since 1280 would be a more round number (320x4 or 240x5). Actually, that makes it still confusing, since it can be 14 x 16 x 5 or 14 x 20 x 4.

The improved perf/mm^2 and perf/W is certainly welcome, especially on 40nm, as is the tesselation improvement

Looks like a big change was that each row of SIMD engines has its own ultra-threaded dispatch processor & caches

So the 6xxx series are supposed to be 35% cheaper. Is this going to happen?

If those prices at $179 and $239 are true... then more than 35% cheaper.

We're talking GTX470/5850 performance at $239 and > GTX 460 1GB performance at $179. Nvidia's margins are going to be in a world of hurt
