Radeon HD 4730 SKU Emerges, Return to RV770

[mdm-adph]

I realy wouldnt want to see card like that...
This new 4730 looks strange, but yes, if they have too much stock of 770, why not to get them out and make some cash from them.

Almost certain they make cards like that -- I know for a fact that 8800GT's were released with 128-bit memory (and I think GDDR2, too). It's a damn shame.

We are pretty much saying the same thing, if you read my original post, that is exactly what I am saying. The practice has been used for decades in the computer world.

What I don't agree with is the name. To me RV770 should be a HD48XX product, RV740 should be a HD47XX product, and RV730 should be a HD46XX product. If they are going to release another SKU using the RV770, call it something like HD4820...

Aye, 4820 would make more sense. However, at least ATI is rebranding a part to a lower number.

I didn't notice the two power connectors. Why the everburning hell would that card need two power connectors? It's essentially a cut down 4850 which uses one power connector.

@newtekie1: you want each series to be using 1 gpu variant only, AMD/ATI bases the series, and number progression as a rough estimate of actual performance.

 

[cdawall]

so basicly we are looking at 4830 with 128bit instead of 256, and GDDR5 instead of 3 to make up for it? and to make that change clear the new name was given?

i would have prefered to name it 4830 gddr5 edition to make that clear, but i understand they dont want to seem like they scam costumers by making them think the gddr5 will make it run faster.

GDDR5 is a QDR spec which means 128bit=256bit GDDR3 which is a DDR spec

The Nvidia 8000 series card look better than that.

i have an 8800GT with that exact cooler.

Other important specifications, such as stream processor count, and clock-speeds are yet to surface. Ideally it should cash-in on a price-segment below that of the Radeon HD 4770.

The frequencies will be 700Mhz for the Core and 900Mhz (3.6Gbps) for the GDDR5 memories.

this one better than 4670 , i guess booth have equal performance

No they don't, the HD4770 easily outperforms the HD4830...

That puts its performance level right with the HD4770, 50MHz drop on the core with a 100MHz bump on the memory should yield similar overall performance. I wonder why they desided on such a low model number, why not make it something like HD4760 if they were already naming it an HD47XX card. HD4730 signifies a card that is extremely weak, one that is boarderline in performance with the highest card from the next lowest series. HD4730 give the impression that an HD4670 should be pretty close in performance...

so is this card able to xfire with those other rv770?, 4850 and 4870?? Maybe for the small price people can fill their xfire slot cheeply?

You can pair it with a RV740 too. That's what CrossFireX is all about. Mix and match the way you want in the series.

 

[Kitkat]

oh put 2 on a card already.

You expresses my feeling to the world

Are you sure? This is really one of the confusing part that ATi brings by using RV770 on an HD47XX card.

In the past, you have had to use cards in at least the same model bracket to do crossfire. So an HD48XX had to be paired with another HD48XX. To me, this always indicated that the cores had to match, an RV770 has to be paired with an RV770. You can't pair an HD4770 with an HD4830, for example, because they use different cores.

So, can we pair an RV770 with an RV740? And can we pair this HD4730 with other RV770 cards?

 

[Mussels]

i'm certain that they need matching cores. 4830, 4850 4870 and 4890 all have matching cores, so they could crossfire. Google around, you'll find that no ones done any benchmarks for a 4770 with a 4870, for example. cause it doesnt work.

Whatever the solution is, it's better for the consumer.

 

[alucasa]

Has anyone noticed the two PCI-E power connectors ? I hope the image is wrong.

 

[newtekie1]

I really don't see how this could be better for the consumer.

Not being able to crossfire with anything would be bad.

And the other solutions just add confusion, especially since ATi can't even be bothered to put out an updated compatibility chart for Crossfire that includes the HD4770.

This card might be better for the consumer, in that it will fill the role of the HD4770, which ATi can't seem to keep in stock. Probably due to TSMC's 40nm fab issues. Though this kind of makes me wonder, where are all the conspiricy theorists now? Where are all those people that claimed the GTX295 was a plublicity stunt when stock started to sell out? Why aren't they crying foul with the HD4770?

Yeah, we went over it a few posts back, its stupid if that is really how the card comes out.

Yes, you can pair them. Also, unlike what AMD told TPU during its HD 4770 review, HD 4770 3-way/4-way CrossFire is possible, and does bring performance increments.

That's what I was talking about. Me likes some cheap crossfire.

Do you have proof of any of this?

I was wrong about the RV770-RV740 CrossFire part. My bad. Here's a chart to help figuring out what works with what: http://game.amd.com/us-en/content/images/crossfirex/CF_combo_chart.jpg

I knew about the tri and quad crossfire part, I was mainly concerned with the ability to crossfire an RV770 with an RV740. As it is right now, both the HD4770 and HD4830 are very similar in specs and performance, yet I don't believe they can be crosfired together. Which makes me believe the HD4730 and HD4770 won't either. Heck, the HD4830, HD4770, and HD4730 are all going to be very very close in performance and specs, too close IMO.
