AMD ''Barts'' XT Prototype Pictured
After recent photo exposés of the Cayman XT (Radeon HD 5870 successor) and Caicos (Radeon HD 5400 series successor), the third, juicy set of pictures exposes the XT variant of Barts reference board (Radeon HD 5770 successor), which will likely go on to become Radeon HD 6770.
While the specifications of the GPU are not known, what we can tell from the pictures is that the card is powered by two 6-pin power connectors, uses 4+1 phase digital PWM circuitry, and looks to have a 256-bit wide memory interface for a near 80~100% increase in memory bandwidth compared to the previous generation. Display outputs include two DVI, one HDMI, and two mini-DisplayPort. There is one CrossFire connector for 2-way CrossFire support. AMD will kickstart its next-generation Radeon graphics series launches later this year. Don't mind the puny looking GPU-cooler, AMD uses it on prototypes. The actual cooler's outline is drawn on the PCB.

Looks very good =)
besides only prototype, I'm hoping for a ram/mosfet unisink unlike the just ram unisink on current 5770s ( rev 1)
It is possible that they will use a cut down 6800 GPU like the cypress in a 5830.
still not a bad card for a casual gamer.
my HD 5870 is nearly twice as fast as my old HD 4870 :p
when you upgrade you should allways upgrade to the fastest card, it is logic
Why did I go 5770? Because it cost me how much my 4890 cost me, so I was getting the same power card yet with lower TDP and power requirements + dx11 support.
Going to a 5870 is infact illogical since its performance does not scale the £100 difference between it and the 5850, 5850 is technically the logical choice in terms of price performance ratio XD
is they going to call it Radeon, i hear there is no more name Radeon anymore it's only AMD.
Edit @ above, see my system specs, I don't run my 5770 at stock speeds.
Edit 2 : The 5830 should be right in line with 4890 now, just had god awful drivers when it first came out.
i do not think it will change, wasnt there some talk about this exacly thing when 4870 was released?
dont belive everything you read online kids
99.99% of it is a lie, and the rest is cake!
maybe they've done it so that performance of these cards just makes sense in the eyes of the buyer, like for example;
the 5850 successor is the 6870, but maybe the performance jump is as good as 5870-6870 in our eyes. having known and used these cards for the past year.
VRMS tend to get hotter than the GPU so you could extract the heat better i would of thought with a stock cooler or better still with the typical type cooler..
Could it be more powerful then the 5830 or maybe it'll match the 5850 once overclocked. LOL (hoping too much), hmmmm time will tell...
Hoping to see this one on reviews.
