AMD Radeon HD 6800 Series Specifications Leaked
Specifications of the upcoming Radeon HD 6800 series GPUs have already been doing rounds for the last couple of days, and ChipHell.com finally managed to leak an alleged press-deck of the HD 6800 series that discloses the GPUs' specifications and some key features that AMD will introduce with this generation. What can be said looking at the slides is that AMD seems to have stepped up performance/die-size big time (up to 35% increase in performance per mm²), with some reconfiguring of key components. It also redesigned the GPUs to have up to 100% increase in tessellation performance, new image-quality enhancements, a new video acceleration engine (UVD 3), and a redesigned display IO with 2nd Gen. Eyefinity technology that can let users of standard variants drive up to six displays with a single card.
Specifications of the HD 6870 are: 1120 stream processors, 32 ROPs, 56 TMUs, 256-bit GDDR5 memory interface holding 1 GB, clock speeds of 900/1050(4200) MHz core/memory(effective), and idle/max board power of 19W/151W. For the HD 6850, it's 960 stream processors, 32 ROPs, 48 TMUs, 256-bit GDDR5 memory interface holding 1 GB, clock speeds of 775/1000(4000) MHz, idle/max board power of 19W/127W.

Now that's out the way neither are better than the other as both do have their problems from time to time. However, with AMD including better AF and MLAA from CCC I can't see why that wouldn't be note worthy additions. That would suggestion they are trying to make some improvements on the driver front (regarding added functionality). As for stability we will have to see as time goes on after the 6800 series release.
Edit:
Oh, btw, Cat 10.10 will be released this week. So lets start with that, :)
And that percentage will increase due to tessellation adjustments.
Bottom line:
* 5850 IS 8.5% faster (in the resolutions that MATTER) than a stock GTX 460. source: source
* 5850 HAS 20% better performance per watt than GTX 460 1GB. source: source
* 6870 will be slightly faster than 5850
* 6870 will have 2x tessellation performance than a 5850
* 6870 will have better performance per watt than a 5850
* 6870 IS cheaper to produce than a 5850 (in case nvidia lowers the price of the GTX460, amd won't have a problem lowering price to stay competitive)
So, 5850 is faster than GTX460, 6870 will be faster than 5850 = 6870>5850>GTX460
According to this an overclocked GTX460 is 6% faster than a stock 5850 and 13% if further overclocked, that's where things get interesting.
Then, a stock GTX460 1GB will be no match for a stock 6870.
A regular overclocked GTX 460 1GB will be equal in terms of performance with a stock 6870 (my guess).
Further overclocking the GTX460 1GB will make it some 7% - 8% faster than a stock 6870.
How much can be the 6870 be overclocked ??? of that i have no idea.
AMD = more problems
Why is it more people complain about AMD drivers than Nvidia drivers when Nvidia has a larger market share?:rolleyes::wtf:
xtreview.com/addcomment-id-13179-view-AMD-graphic-market-share-higher-than-NVIDIA.html
OH noes the silicon reserves are running out! :laugh:
If that's right and actually works well it would make choosing monitors for an eyefinity setup much easyer, although the price of the hub may be silly just like the active display port converters used to be.
From the spec it looks like the 6870 would be a very nice upgrade over my 4870... but i think i will still be waiting for the 6970 :D
so please stop the trolling
I spent almost 70K at newegg in the last year doing builds for work, clients, friends, family..... alot of others here play with tens of thousands of dollars in hardware for their personal rigs.
I have owned every ATI card series except the 2XXX series as it truly was shit. I have owned GeForce cards, and recently helped with a friends 460 upgrade from a older Nvidia card. It works well, but I could hardly navigate their control panel. He likes it, so ace for him, he has only used nvidia and has a perception that they are always better than ATI/AMD in everything. So despite having a better online video upscalling/display, lower power requirement, running cooler, running his games faster, for less money available he chose the more expensive option as it seemed to be a better product.
Comparing the GTX460 to HD6870 is pointless anyway, because Nvidia will not position the GTX460 against HD6870 once it is released. They will release a GTX475 or whatever they call the full blown GF104 card. That card with 15% higher shader count and probably a 10-20% higher clock (750-800 Mhz) will be about 25-40% faster than the GTX460, making it substantially faster, decidedly faster than GTX470 and maybe even faster than HD5870.
It's true that on the $200 bracket AMD will have the clear advantage in perf per cost of manufacturing and perf/die area, but why? Only, because of releasing their $200 card later, they have been able to position their full blown chip against a crippled part. It's the same as when they say that HD6870 is better at perf/die area than HD5850. They are comparing a fully enabled chip against a crippled and underclocked part while boasting the die area of the fully enabled Cypress die. But oh well, that's the same stupid mistake that so many people have always made with HD3870 vs 8800GT, HD4870 vs GTX260, etc etc.I'll wait until numbers are posted, but that's most probably false. In Q2 AMD had 52% market share, true, but I would hardly call that the majority.
No official numbers have been posted that include GTX460 sales, not to mention GTS450 and below cards. Meaning that AMD achieved that 52% with the complete HD5000 family cards vs GF100 + GT240/220 etc. It's nice to see competition and wanting AMD to be ahead is nice and all, but keep it real. Steam Hardware survey makes it very clear that GTX460 has sold A LOT more than any other card. In just 2 months it's user base (DX11) has increased to 5.5% or more than 1/6 of what HD6800 (3 cards conbined) has sold over a complete year.
Not only that but every single AMD card has seen a decline in DX11 share, while every Nvidia card has had an increase, so that clearly suggests that as of late Nvidia is outselling AMD. Also considering that Nvidi still sells DX10 cards, while AMD doesn't anymore.
Anyway if nvidia positions GTX460 1GB at a lower price point, lets say 200 USD, then it would compete with 6850 and beat it, you really think amd would let that happen? no way.
Crippled or not i'm comparing price points, so that's what matter.
GTX475? not even seen any info on when will be released, not even rumours, so lets stay at now.
Right now amd has the upper hand, that's irrefutable, like nvidia had it whe released GTX 460, talking about mainstream.
When GTX475 is near release, then we can talk about it. (maybe when it happens, cayman will be out too, so the argument goes on and on...)
At the end we win if prices go down, so lets hope nvidia does what you say and put GTX460 at 200USD, that would be awesome.
EDIT: there is one at 210 USD woot! here
No.
I probably had hardware conflicts.
Such a stupid argument to have.
If the cards work for you who gives a crap, if they didn't work for you don't assume all cards are going to be the same.
ma·jor·i·ty
1.
the greater part or number; the number larger than half the total
:p
But you are right about what the numbers include, the fact that the higher selling cards (lower priced) are not included means a lot, but it is also very hard to accuratly list market share with gpu's as its constantly changing so fast with new products and people upgrading between companys.
Some of that 52% could have just been waiting for cards like the 460 or people with low end ati gpu's could have been waiting for the 450, i geuss in a way we will never know for sure unless one company really pulls away from the other again in market share.Damn straight :D
The reason that you have heard nothing tangible about the card yet is that Nvidia probably prefers to let it be that way until they have to release it, which is what happened with G92. If you remember the release of G92, the paralellism with GF104 is amazing. Back then Nvidia released the crippled part firts, so that it didn't eat up on 8800 GTX sales and many people thought that Nvidia could not make the fully enabled part and also the mere existence of the 8800 GTS was nothing more than rumors, almost confirmed rumors, but rumors after all. And that's exactly what happens today with GF104 IMO. Back then AMD didn't have anything to compete (here ends te parallelism), whereas now it's Nvidia who will have to compete, but the reason for secretism is the same.Yeah correct. My mistake. I was going by the main meaning in Spain, whose translation is "most".
I want 5850 perf at 199 USD yay!
Back on topic though, we won't know the real ingame speeds untill friday so to me most of this is just talking to pass the time untill the reviews arrive.
