HD 4770 Previews/Reviews

If you can charge $99 with the crappy cooler or $109 with the good one, considering those costs, which one is going to be better? It's too obvious

When you plan on selling 200k cards, the price difference can add up quickly.
Remember these cards/coolers are just for the initial launch, AIBs can design their own cards/coolers.

there is a LOT to be said about the "$99" price point - a product with 3 digits in the price tag is guaranteed to sell less units. period.

Or you could just put a 3rd party cooler on it. I know that at least the Zalmans wil/should work.
I want a single-slot vapor chamber cooler. Sapphire are you listening?

Isn't the 4850 $129. It would be absolutely ridiculous to make overclocked models that are 30 dollars more expensive than their regular counterparts.

I know there's a recession and all but is 50 dollars that much to spend to get a 4870.

I also think it ridiculous that people upgrade from a 8800gt to one of these cards. As a 20% increase does not warrant a upgrade.

lol, $99 for:
- 20% more performance across the board (more in high quality settings)
- a dx10.1 card that can do more dx11 functions
- a card that runs cooler, and uses less power


..... definitely not worth it

The heatsink is already designed and ready. There is a market for them (i.e. anyone who wants silence / low temps / good overclocking). If they don't sell them, it would be a shame.

Oh, and the "goddamn noobs" (and people who do not need a good cooling solution for some reason) can have their $99 card too.

[Wadkiller]

I'm going from a 8800gt to to of these. I did'nt buy my P5E for nothing. I can sell my 800gt & thermalright HR 03 GT fr R1000 ($100) & jus add the rest for another 4770. The cheapest 4870 512MB in South Africa costs $260, the cheapest GTX250 $380, so you can imagine what the high end gpu's go for.

I'm definitely going to crossfire two 4770's I'm getting my 2 Dangerden Mazew 4 during the week, so i will be watercooling these babies

Power consumption is really horrible compared to a higher performing 4850 in that review. And Idle....yuck

GDDR5+40nm=Phail!

u mean consuming less then 9600GT is fail? More looks like Shintai = reading skills phail

And the 9600GT is a 55nm part thats over a year old.

One of the biggest issues with HD4770 is the missing idle mode(Powerplay?). It runs at full clock even idle. And specially GDDR5 is a pig.

Hopefully AMD fixes this for idlemode atleast. And we can only hope for lower voltage GDDR5 soon.

I can understand that you have really high expectations, so I would say wait for 4750 GDDR3 based. I know it will have only around 32GB/s bandwidth, but power consumption numbers should be excellent. For HTPC computers it should be a winner.

for customer:
equal or better performance between 4830-4850
about 10% reduced idle and 20% load
less heat
huge reduced price

for amd:
way lower production costs
lower pcb cost
testing of new process

again very well based comments you make as usual.

[LightSpeed]

maybe the final review samples will further reduce idle power consumption?

In case, it looks to be the perfect <$100 card

[Wadkiller]

I wish we could see some results with them in crossfire.

Can someone plz explain to me how the memory sharing(?) works. If i have two cards with both 512MB, do i only have 512MB usable for both cards? So is the official release tommorow or during the first week of may?

[Rasamaha]

4770@875.1125

[Wadkiller]

Nice Rasamaha! Is that with stock cooling?

[Rasamaha]

Nice Rasamaha! Is that with stock cooling?

Yep! in auto mode! so it's not 100% of coller

[Macadamia]

O-m-g.

[Wadkiller]

I only saw the mem speed now! 4500MHz effectively! I can't wait to get my hands on this. I'm sure there will be some super clocks!

Is there someway to test the bandwith of the mem on the gpu? i'm sure the 128bit won't matter so much anymore

[trinibwoy]

No need to test it, it's 72GB/s ~ GTS 250.

[Lightman]

This card is shaping up nicely!

So who is going to put it under LN2 first?

[oohms]

I wonder how 2 of these voltmodded and oc'ed would stand up to an overclocked gtx260 (now that they are really cheap)

[SKYMTL]

Finally got a card on Friday from an anonymous source. Then spent most of the day sending emails to my rep at ATI for drivers without a response, spent the better part of the weekend calling in favors to get the most current drivers sent to me off the grid.

No thanks to ATI, a review will be up one way or another.

@ Rasamaha: would you mind telling us which program you used to bypass ATI's CCC overclocking limitations?

And 4770 outperforms the 9600GT by at least 40%. Yeah, that really sounds terrible. 9600GT is a year old 55nm part - that means the 55nm process wasn't even new when it came out. This is the first 40nm card and it performs like this.

But sure, the idle consumption is a . Can't someone reviewing it PLEASE downclock the GDDR5 in idle and measure the power consumption.
