AMD: Southern Islands (7*** series) Speculation/ Rumour Thread

Ability to pair up different size monitors is awesome.

Going by the yellow triangle on the leftmost image it seems like the monitors have equal resolution, just different physical screen size.

Of course it could just be a photoshopping error :)

It most definately is error, if you look at the actual scene everything lines up perfectly
 
If it's faster than GTX 580 it will cost the same or more than GTX 580. We dont have to like it but that's the way it will be.

That's not always the case. 4870 was almost as fast as GTX 280 when it was released, but the price points were drastically different: 299$ vs 650$.

But this came after the almost disasterous years of 2900XT and 3870, both of which were beat by the 8800GT. AMD (ATi) needed to gain some good will by having high performance at lower price. I think they believe they are at the point where they have enough PR capital from the good 4xxx-6xxx years to increase their prices again.

I still hold that they are wrong, and a £500 gfx card thats only 20% faster than a 580 will be a laughing stock. At the very least, NV will drop the 580 prices, release a 580Ultra which matches it for perf and price. And people will buy the cheaper 580 rather than a 580U or 7970.

If memory serves, the 5850 is a better example, as it actually was both faster an cheaper than the GTX 285.
 
I suppose, but it was similar in performance to GTX 260 and thus probably priced thereabouts (I dont remember exact pricing at those times). This would be a new high end.

NV cut nearly half of GT200 price after R700 release,then they probably priced thereabouts.

R700 is a special case,AMD made a huge bet on GDDR5 and won.

Considering pad-limits for GDDR5, would be even 5Gbps GDDR5 possible @125mm²?
Since Cape Verde might have only a single-setup, it probably scale it execution-units by 2.

My guess:
10 SIMDs (640SPs/40 TMUs) @1GHz + 128-Bit@4,4Gbps. Performance especially in D3D11 a bit over HD 5770/6770, many new features and a price around $100.

It's extremely unlikely that HD7700 would lose to HD5700/6700 in anything, so I'd say it has to be around 6800-level to be safe.

I also thought it would be 10CU,but....

I think CU count has to be a multiple of 4, so 10CU isn't possible—unless GCN is a bit more flexible than we were led to believe.

So,it more likely will have 12CU.....performance around 6850 probaly...

In D3D11 games it probably will be.;)
Do not forget, that Turks (480SPs VLIW5, 128-Bit) will go for HD 7600/HD 7500 series with no additional features.
My suggested Cape Verde would not be such bad, compared to these.:LOL:

I know. But do you think Cape Verde will be "dual-core"/double-setup-engine?

The memory controller itself is a big chunk of logic also, so I guess this one will use the cheaper implementation for low clock-rates. And we still don't know how well padding elements scale with the 28 nm process.
