As we know, the new generation HD4600 (HD4650 and HD4670) mainstream segment graphics is coming and the memory lowest specs are 512M GDDR3.

HD4600 will use kinds of memory they even possible have 1GB memory version products. The memory clocks are 1400MHz Qimonda 512M GDDR3, 1800MHz Hynix 512M GDDR3, 2000MHz Hynix 1GB GDDR3 and 2000MHz Samsung 1GB GDDR3. The high-end HD4670 probable use 2000MHz GDDR3.

The low-end HD4400 will start from 512M GDDR3 and there will be 1GB memory version, too. They will mainly use Hynix 512MB GDDR3 and SAMSUNG 1GB GDDR3. But the clocks of HD4400 are all 1600MHz.

Interesting, it's been like never since AMD(ATI) has tried to nail Nvidia to the grave.
 
Revamped Radeon HD 3800 series that more resembles RV770 (do away with the ringbus etc) ?

That would make for a quite powerful low to mid-range combination that would target the Geforce 9600GT.

On the other hand that might be too much in regards to the targetted Thermal Design Power and performance, not to mention the transistor budget. A pipe dream I reckon.

I think TDPs on the new revs of 3800s have been reduced as a result of lower voltages, and that's what the mobile part has been doing already. When you can have a mobile part, DT TDP is definitely not a problem, even when accounting for cherry picks.

As for transistor density, I wonder how much it really matters versus die size from the end-all cost/perf/watt perspective, though.

If they wanted to spank the 9600GT it would be as easy as a matter of RV670 redux with the tex units increased to usage levels. This would actually keep the 4850 constant at the 150-200 level while the 4600s would price below instead.

128-bit bus? :LOL:
 
I think that's highly possible to be fake.

Vcore numbers seem... off. And ATI pushes clocks on their SKUs more aggressively than that.
