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.

power phases on the front of the gpu with what appears to be (from the outline on the card) a double slot exhaust cooler? it doest seem like the smartest idea

Anyone else find it strange that the 5770 successor has two 6 pin power connectors? Maybe just for prototype reasons?

this looks to be one hell of a mid range card. My 4890 is starting to get dated rather fast. If a 5770 was roughly about as powerful as a 4870, I can only imagine where this one stands performance wise.

Seems smart to me, as a midrange card heat-output from the mosfets will be negligible so having warm-ish air flow over them shouldn't be to much of an issue.

besides only prototype, I'm hoping for a ram/mosfet unisink unlike the just ram unisink on current 5770s ( rev 1)

hmmm interesting, if the middle of their range, ie 6700 series, is 256-bit and requires 2 power connectors, one can only wonder of the 6800 series.

It is possible that they will use a cut down 6800 GPU like the cypress in a 5830.

If a 5770 was roughly about as powerful as a 4870,
tell me about it - the 4870s 256bit mem interface really pulls it ahead and the 5770 even though can overclock really really nicely will never overthrow the 4870s at anything above 1680x1050.

still not a bad card for a casual gamer.

yeah I thought the 5770 sat nicely between the 4870 and 4890, 256 bit memory bus has little to do with it here, the 5770 has been under the driver spotlight for a year now, not to mention it has ample memory bandwidth anyway.

why did you buy 5770 then?
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

It seems 6000 series will have a strange nomenclature. HD 5870 successor = HD 6950, HD 5850 successor = HD 6870, HD 5970 successor = HD 6990 (?). Something like that..it's messy.

May be they are doing it to go along with the ATi to AMD name change ... :shadedshu

I think you've mistaken logic for having money to spend :laugh:

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

LOL just like NVIDIA in old times, when release the GTX260 core 216 and the 55nm GTX 2xx.

is they going to call it Radeon, i hear there is no more name Radeon anymore it's only AMD.

There will no longer be ATI, how ever the cards will still be Radeon HD XXXX.


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.

might just be FUD as we know ;)
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

*sigh* thats really odd, since the 3xxx series I thought they were onto a good thing with the naming scheme, excusing the small drop of X2 cards for the 5970.

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.

power phases on the front of the gpu with what appears to be (from the outline on the card) a double slot exhaust cooler? it doest seem like the smartest idea
Been waiting for them to put them at that end of the card forever it feels lol. Although i can fully understand why they are normally at the other side.

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..

Looking forward to Barts spects. Hoped for low TDP, but those two 6-PIN... can't believe they will be there.

Thought they were saying the 6770 was just going to be a re-badged 5770, if the bus is bigger that's a good sign. Really wish they'd not mess with the naming.
