Yeston Designs Radeon HD 5770 X2 Graphics Card

Now that AMD seems to have given the 40 nm Juniper GPU (on which are based the Radeon HD 5700 series models) a new lease of life, manufacturers can continue to get innovative with the Radeon HD 5770 GPU. One such board partner, Yeston, designed a Radeon HD 5770 X2 graphics card, which simply put, is a dual-GPU graphics accelerator that makes use of two Radeon HD 5770 GPUs, each with its own 1 GB of GDDR5 memory, that share the PCI-Express interface using a PLX-made bridge chip (perhaps the same one used on the Radeon HD 5970).

The PCB holds both GPUs on the obverse side, the PCI-Express bridge chip on the reverse side, and memory chips on both sides. A 4+1 phase VRM is used, additional power is drawn in from just one 6-pin PCI-E power connector. Both GPUs work in tandem via an internal CrossFire interface, it can pair with another Juniper-based graphics card for 3-GPU or 4-GPU CrossFireX. The duo are cooled by a large heatsink, air is circulated by two 90 mm fans. AMD reference clock speeds (for the Radeon HD 5770) of 850 MHz core, and 1200 MHz (4800 MHz GDDR5 effective) memory are used. Display connectivity includes two DVI, one HDMI, and a DisplayPort. Knowing Yeston's reach, it's not very likely that this card will be sold in the US more towards the Asian market.

5850 power with 1 6-pin? :eek:

This looks incredibly small for a dual gpu card and low power consumption it seems... that i like, now if all graphics cards made from now on would be this size that would be great.

Meh. It's a 128-bit 4870x2. Not really that exciting, I'm just very surprised they pulled it off with just 1 6-pin. But functionality wise, 128-bit bus makes it useless for myself.

Well duh, you have 2 x 5870's this card regardless of the 128 bit should sit it right between the 5850 and 5870 performance wise even with its 128bit, and the 5770 is actually a little better than a single 4870 performance wise, price wise and in terms of power, so this card should be win dependaqnt on price.

Shouldn't that be 4800 GDDR5 effective? :

Yeah, this. Interestingly few components on the board too.

Am betting its an Asian partner that manufacture cards for the Asian market, there are quite a few out there who make both NV and ATI cards I had never heard of before.

? why

I don't know why they would make this so late.

The price of the 5770 dropping?

Crazy 4 TPU!!!
It's a bit late in the game for something like this, very surprising card to see though, and this just uses one six pin, that's awesome. Probably equivalent to a 5850 depending on how well it scales, then again, i'd rather just get a single 5850 with 100% scaling and move to a second one later on down the road.(they're pretty cheap now anyways)

Makes this news even more pointless for me...

The card seems to have a lack of power delivery components, but I know very little on these things. AMD/ATi must have quite an excess of these GPU's.

..And that makes me question a rebrand...wouldn't they be using these gpus for that, if the rebrand was true?

Or are yeilds that good(which bodes well for the 6-series...)...


I'm still blown away by 2 gpus, bridge chip, and mem, with just 150w available..that's killer. A compare between this and 5850 would be really nice to see...what does a 5850 pull?

I'm surprised it took this long for cards like this to show up. Though I epxected Sapphire to put one out pretty quickly(they are the master minds behind the x1950Pro Duo).

I'm still surprised that someone hasn't put together a dual-GTX460 card yet using an nf200.

Because in a couple of months they can just rebadge it the HD 6770 X2.

I have a hard time believing the legitimacy of this card with only 4 phase analog (2phase per GPU , really?) and 1 ram phase... I wouldn't overclock it that's for sure.

under cross fire scaling it may actually weaker than 5850....and pretty much down clock too(assumed) because 1 6pin is impossible to maintain two gpu like juniper...

The original card was only a 3 Phase(or maybe 3+1) IIRC. So a 4+1 setup shouldn't be a problem, especially with the tiny power draw of the HD5770 to start out with.

It probably won't overclock as well as a single card, but it probably has overclock potential still.

True, now that I look back I see the ref is 3+1 phase. (I was thinking of non ref which some have like 6 phases)

well if that is indeed adequate power then it looks like a neat little card.

Why would anyone get this over a single 5870? I guess it depends on the price :

the rebrand is for Barts and Cayan chips not the cypress and downward chips.If the mid range like the 6770 runs at the 5870-5890 it makes sense for them to rebrand them the 6870.Also these chips will still have the ATi logo on them, from the 6870 onward they will have AMD or just Radeon on the chip itself. As for this card it will go well with the HTPC crowd who want a gamer box also.

Rumour is that Barts is 6850/6870, 5770=6770, and Cayman will be 6950/6970.


5770=6770 is reported last week, as you can see here:

What happened to 256bit?

Indeed! My 3850 runs 256bit on the old AGP bus...WTH happened?...all the new stuff is 128!
