6770 full specs

Compared to 80 TMUs and 32 ROPs for the 5870, sounds reasonable.

So 5870 had 1600 shaders but if we are to believe the rumours they are only 4/5 efficient compared to 6970 so in theory that means 1280 vs 1920

That's a best case scenario, but yes. 1920 on the "6970" vs somewhere between 1280 and 1600 equivalent on the 5870. The 5th SP in each group was not entirely useless, although not as heavily utilised as the other 4 (as lightnix highlighted in another thread; see here).

There may also be other 'per-shader' efficiency improvements, due to improved command and control logic, and improved 'per-shader' memory bandwidth. We will need to wait for final specs or a GPU schematic to discuss that with any confidence though.

for the non clued up members, what does all this mean ?

It means: Expect around about 30-35% performance improvement for the top-end single GPU (6870 or 6970 or whatever they decide to call it), over the 5870.

It will depend on the efficiency of the new x4 (rather than x5) shader grouping, and also on clock speeds and memory bandwidth, which we don't know yet. But that is your rough ballpark.

Also, the new mid-range cards ("6770" or "6870") will be effectively 2/3 the chip of the top GPU, as opposed to half with the current generation. Expect them to come in at around 5850 performance (a little above for the "6770" and a little below for the "6750").

As for pricing - all still speculation.
 
I dont understand how those leaked 'Barts' specs are meant to be a 6750 / 6770 class card.

Isnt the *7** range meant to be low cost but powerful?

It seems a shame if the specs are true, that they are making the midrange more and more expensive. Theres no way that a 40nm based card with those specs will retail for under £200, and thats really not a *7** range card IMO.

I wouldnt believe those specs until they are officially from AMD.

Oh, as an above post suggests, they're probably changing the naming scheme, yay, more confusion for the customers!
 
Oh... So many people don't understand the market share and why pricing is what it is. First of all, 6000 series must be better performance:price ratio than the current generation to be even considered by the public. It means that 6770 (or 6870, depending on what they decided to label them) will be priced at $300 or below (as was 5850), being the faster of two. But the market has been fed-up with 460s, 5850s and 470s recently. This means that the card must be priced lower than 5850 because it's the only step-up they can do. Replacing the current generation only makes sense if the price buckets are full of better products. They will be because 6000 series will use less power whilst maintaining higher performance (slightly in mainstream, significantly in high-end). We can't talk numbers yet but come on, be smart and understand how the economics works. When the current generation is sold-out, they might indeed increase the prices of 6000 series if Nvidia doesn't come up with a reasonable solution (dropping their pricing isn't one unfortunately, their cost:profit ratio is much worse than AMD's products').

There might be some price confusion during the launch, when people are overly excited or uninformed and willing to overpay for hyped products. There's little to none chance that 6000 series will fail though. Think of the pricing in a simple way, price brackets are usually set to $200, $300, $400, $500 and $600. Anything in between is possible but that's what generally is taken into account with AMD's graphics cards. There's also about 15-20% you'll have to add on top of these prices. This is strictly VAT related and also has a little to do with exchange rate (cards are priced at the exchange rate current for the day of purchase from the supplier). So $230-240, $345-360, $460-480, $575-600 and $690-780 for the UK prices. I'm not saying these are the exact figures but you can also have an idea of how the "5%" affect the end-user prices.

Regarding the launch date, it's all speculation yet. There's no official delays but leaks of delayed information that tells us whether the cards will be released in November or late October. Don't take anything for granted, any "news" may be well outdated at their release.

A quick note on changing the names, it would make sense if AMD wants to keep selling some of the cards from current generation on the market. Relabelling to 6750/6770 anyone? :p It's all a little confusing now and any dispute is pointless with so little info we have atm.
 
I'm just in a small insignificant boat of people that wants there to always be better performance at <£150 in every generation.

Like the 3850 > 4850 < 4770 > 5770 > GTX 460.

Whats next at this price point from AMD? Doesnt look like its going to be the Barts, and thats probably why it seems to be renamed to the 6800.

It's most likely going to be the Barts, 6750/6850, whatever they decide to name it, will be fighting at this price point. Is it going to be worth it though? Would you switch over to a used 5850 if you had a chance to right now? It's all down to the personal taste. Definitely if you can spend a little more, 6770/6870 looks like a killer. It may be priced at £190-210 though.

That "small, insignificant boat" you're in is actually one of the largest markets atm.
 
I wouldnt have actually switched over to the 5850 because of its weak DX11 performance (since two 5770s get the same minimum frame rates as a 5970 in DX11 benchmarks, I wouldnt have wanted to spend more on anthing higher in the HD 5000 range).

I did switch over to the GTX 460s, and while the Barts specs do look a lot better, Im just mostly concerned about what happened to the 5770 replacement, as the Barts is actually a 5850 replacement?

My next upgrade will be 28 nm though, not these.
 
You're getting it wrong, Barts isn't 5800 replacement (or partially is), it's going to sit comfortably between 5700 and 5800. Or thereabouts.

5800 are weak in tessellation on its own and that's about it. It has nothing to do with gaming performance that most if not all are after.

We've yet to see how 6000 perform in reality, it's worth waiting for some official info/unofficial benchmarks though :)
