No. My 830 Mhz overclock was not held back by the cooler but rather the CCC.

Update: ATI not thrilled
Update: ATI has officially confirmed that it does not allow partners to overclock the HD 4770, at least not for the time being.
Revolutionary. I imagine profit margins are quite good on these puppies. If I was ATI I would discontinue the HD4850 right about now... and start making an HD4790.
Brilliant. Thanks for the effort.
To comment on the nvidia out selling ati... the problem with that is it must be true. Simple reason is: I don't know anything about hardware, yet I have heard of "Geforce" and "nvidia", and I probably figure a $130 investment in a video card makes sense, so I buy whatever is in that price range and fits the bill.
Of course I am referring to Americans (who probably make up the biggest market). In europe, this might not be the case at all. On average, people in europe and asia are more knowledgeable in these matters.
In addition, retailers often stock a lot more nvidia variety (oems) than ati. Mostly due to demand and availability...
I haven't found Bit-Tech's articles to be biased one way or another. Am I missing something?
It'd be nice if 900/1000 or more becomes standard overclocking potential for these card. It'd make for an amazing cheap powerful crossifre setup. It'd be nice if they release the 3870 style stock cooler version for the same price as an aftermarket cooler needed for overclocking a $100 card is a fair amount of the card price.
The good thing is seeing the potential of these cut down cards it makes the potential of the 40nm 5000 series cards seem very promising.
I dunno about bit tech being biased or not,but 2x4980(CFX) is definitely not equal to GTX280 but way faster than that and roughly equal to GTX295... Maybe that mod got confused somehow and said 280 instead of 295.
these cards are now on newegg $109
but it's the cooler shown in the reviews.
no triple support and no quad even though they're be really nice too nice for ATI to do so >_>....
-_- disappointing.
needs faster mem:
Quote:
The performance benefit from the 20 percent overclocking for the GPU and 25 percent for the memory is impressive: On average the card is running 25 percent faster, that indicates a relative bandwidth limitation by the 128 Bit interface.

I'm hoping 1000/4800 with a better cooler and ramsinks.
That would one heck of a marketing bonus, 1GHZ for a HD4790..
ATI doesn’t want overclocked HD 4770's

Not for now
http://www.fudzilla.com/index.php?op...13407&Itemid=1Quote:
We've talked with some top ATI guys today and they wanted to make it clear that for the time being there won't be any overclocked Radeon HD 4770.
As you can read here, Asus obviously jumped the gun disobeying ATI’s instructions and naturally this made a huge reaction from people like Sapphire, XFX and other ATI partners that would like to overclock their own cards.
Today, ATI doesn’t want to see any overclocked card, but this might change in the future, as overclocking potential is there. ATI just recently started letting its partners overclock, but the big issues here is if Asus starts shipping such an overclocked products, the others will want to do the same, and ATI loses control.
We believe that this decision is strategic as it can offer second sales wave once the overclocked cards are eventually introduced, and Nvidia often uses the same strategy. One thing is clear, there won’t be any overclocked HD 4770 anytime soon.
(Follow up to: Asus has the first overclocked HD 4770)
overclocked would mean itl be equal to 4850 speeds, and that could be a problem i guess
1ghz mem is too easy for this card, and that alone would boost speeds by quite a bit
I find it odd that reviewers are comparing at HD4770 to a GTS250/9800GTX+ :ROTF:. This card is targeted for the 8800GT/9800GT and what would have been the GTS 240. And if I remember correctly the the Sparkle and Asus verison of the GTS 250 uses 2 PCIe 6 pin connectors. Furthermore, the GTS 250 cost more then a HD4770 even at their current markup price. Heck I've even checked NCIX and the GTS 250 still cost more then a HD4770. So I honestly don't see why the HD4770 is compared to the GTS 250 specifically.
This card is amazing in CROSSFIRE. They have a review over on Expreview that shows 80% scaing overall through a bunch of games and with 2 4770's the crossfire setup is on average 20% faster than a 4890.
This is insane imagine what it could do with 2 in crossfire with good cooling (Trad2/Twin Turbo/S1 Rev.2) and overclocked to 900/1000-1,000/4,800 could do. I think we may have found ATI's 8800gt finally.
Eastcoasthandle, I think it's because it often outperforms those at it's price point by such a margin that it's a better comparison between the next higher priced cards.
Ninja edit: That assus card above is claiming 971/4,600 with their volt mod software. So we may hit that magical 1,000/4,800 mark with rivatuner and perhaps if needed a slightly higher voltage.
Personally, I think it is because of the performance of the HD 4770 in certain games when compared to the GTS 250 / 9800 GTX+. While I find it is important to test against a wide variety of competitors, there is no denying that the performance of this card is in some cases close to or exceeds that of the GTS 250. However, testing the HD 4770 against ONLY a GTS 250 shouldn't be done due to price factors.
SKYMTL, based on your tests, do you think at 825/950 (which should be doable) this will match the 4850 or exceed it?
Gigabyte Announced their 4770 Today...
GV-R477D5-512H-B is the model name...
Personally, at some point I think that the 128-bit bus will become the limiting factor on these cards' potential for increased framerates through overclocking.
The way I think of it is this way: if we take a HD 4770 and overclock it to HD 4850 performance, we can equally take that HD 4850 and overclock it so it maintains its lead. I would always rather take a higher performing stock clocked card than overclocking a lower-priced card and hoping for stability. Especially when the difference is ~$30 at some retailers.
at 825/950 I think it will succeed HD 4850 based on results over the web
Really seems like a good and cheap card. This competition really could bring back focus to the PC game scene.
Once again thanks for the reviews recap onethreehill :up:
better question is how 6.6gbs pixel fill rate 4770 OC can out do a 4850 with 10.5 pixiel fill rate. ???
:confused:
and that's with 4xaa 16xaf.
I'm a bit confused. HR-03 A fits both X1650 and 4670 according to TR, but in your review you say the 4770 has the same holes as X1650 but different to 4670. :confused:
The VF-1000 also uses the same mounting holes for both X1650 and 4670.
Try check your own review as one example. % core clock OC, % mem clock OC and actual gain.
Your own 10% core, 38% memory. Yielded ~17%.
http://i5.techpowerup.com/reviews/AT...es/perf_oc.gif
You can try again just with the memory?
What happens when you can buy a 4850 @$89 after a $20 rebate and by using the promo code "VGA851"
http://www.newegg.com/Product/Produc...82E16814102824
Not really.
One: Your statement about over clocking to 4850-level performance is misleading. The 4770 should be able to OC quite a bit past 4850 performance. Even if you get the most crappy 4770 in the world you could probably increase the volts, OC past 4850 levels, and still have way lower power consumption.
Two: The memory on the 4770 is under clocked by default from the rated 4GHz. Restore the memory clock to the rated spec and you've got a part that should be slightly leading, and not slightly trailing, the 4850. There's no practical reason why we shouldn't look at 4GHz memory clock as "stock".
Three: 4850's aren't really known for over clocking well, and while it will obviously vary from card to card, I think that when you overclock both, the 4770 will more often come out ahead.
So, in my view, cheaper price + better thermals + better performance (on average, assuming both are OCed).... what's not to like?
Speaking of comparing both cards over clocked, that's something I would like to see more of in reviews -- not just seeing which card is faster at stock, but who comes out when both are pushed to their limits.
*nudge, nudge*
any single slot 1gb version on the horizon?
We got ~20% overall performance boost from overclocking 13% on GPU and 37% on memory (850/1100). I'd say both GPU and memory clocks are equally important as far as scaling is concerned, this is a sign that the memory bus width is rightfully chosen. The main idea behind the 128bit+GDDR5 is to make the PCB cheaper, i'd say AMD hit the spot from the price/performance standpoint.
What i find most interesting though about this card is the fact that two HD 4770's in Crossfire marginally beat the GTX 285, wich is almost double the price of both. If it weren't for the stuttering we get in actual gameplay with multi-GPU configs it would be the best solution there is. Here's a link to our article where we tested this:
ATI Radeon HD 4770
XFX Readying 1 GB Radeon HD 4770 Variant
http://www.techpowerup.com/92732/XFX...0_Variant.htmlQuote:
Following ASUS, XFX is another partner breaking away from the reference design mold for the Radeon HD 4770 accelerator soon after its launch. The company is ready with a variant that features 1 GB of GDDR5 memory. For now, a picture of only its box can be found from an promotional page of the company, with links leading to its 512 MB base-model, but what the one picture we have, reveals a rather lavish packaging. The "X" shaped box shows no signs of a "XXX" branding, or anything that suggests the card features factory-overclocked speeds, though the "1 GB GDDR5" is legible. The card is backed by the company's "5-star" warranty. Its pricing and availability are not known.
http://www.techpowerup.com/img/09-04-29/79a.jpg
That X shaped box is just retarded :|
But a 1GB card sounds good.
Need some help here plz.
Do I wait for the 4770's to be released in SA & go crossfire. Or get 2 1GB 4850's or one 4890?
"says who?" right back at ya. .. sounds like bs to me.. but i'll waste my time and give those combinations a try
edit: while the system is booting up with new cards i googled that:
http://img.techpowerup.org/090429/Capture176.jpg
hd 4830 + hd 4770 = no cf + system hangs/bluescreen when starting ccc
hd 4890 + hd 4830 = bluescreen at startup.
nuked the amd review drivers and switched to 9.4
hd 4850 + hd 4890 = works
hd 4830 + hd 4890 = works but gives "mismatched but will still work" warning
hd 2900 xt + hd 3850 = no go
so in essence, cf only works with identical asics. rv790 is rv770 with a few non-architectural/non-instruction changes (rerouting of signal lines inside the gpu)
There's a new one, on stock, just air, no mods at all, Vgpu 0,95v....1000Mhz will be possible with 1.0-1.05v on GPU.

i havnt kept up with the whole thing, but has power consumption and heat been improved. i think its a shame that its between a 4830 and 4850 in performance and heat, but with the die shrink should be a killer in the perf per watt. i would have upgrated my card with this if the power consumption was where a 40nm with gddr5 should be.
Is there a consensus yet on overclocked 4770 vs. overclocked 4850?
HD2900 and HD3850 can be crossfired, I've done that when HD3850 was just released. I believe it was Guru3D that tested RV670+R600 crossfired successfully back then. I agree with you only identical asics can be crossfired, but only because the driver allowing which cards can be crossfired. The reason is probably really simple, to be sure customers don't have problems with combining totally different cards. With older (modified) or beta drivers there's a change hd4770 and HD4830 can be crossfired. To much hassle off course and not doable on the long run.
it's right there in w1zzards review ? on TPU...
Page three on the review.Quote:
The HD 4770 supports CrossFire configurations with two cards. I did confirm with AMD that there is no support for CrossFire triple or quad. It wouldn't make sense on such a product anyway.
i specifically asked amd "does it support triple or quad configurations?" their answer was "By design, the 4770 is limited to two cards in CrossFireX"
hadn't seen that review,found it on amd's product page-

Why would you want to crossfire different model cards anyway? ATI have enough driver problems with regular crossfire (but getting better), crossfiring different models is just asking for trouble.
perhaps triple and quad crossfire disabled over stuttering concerns.
Radeon HD 4770 Media Edition VS Retail Edition
http://en.expreview.com/2009/04/30/r...html#more-3356Quote:
Besides Radeon HD 4770 retail edition, AMD has actually prepared another edition for media’s test. The two editions look quite differently, but perform almost equally. As you can see below, the media edition is designed elegantly with a more effective cooler.
The media edition brings 2-3℃ lower temperature than retail edition, but it causes more noises when the fan runs at maximum speed. Let’s check out together what differences they have. The above one of each group is media edition, and the other one is retail edition .........

Funny thing is that the retail edition will always run at max speedQuote:

Probably if the clocks were different and with additional memory. The GPU and memory will probably perform within 0,1% of each other between "review" and "retail". Maybe the OC is different but it seems like everyone is hitting the 830MHz boundary so that doesn't seem to stop it.
830Mhz is the upper limit of the CCC so the fact that everyone is hitting that doesn't come as a surprise. Judging from what I see, power consumption may be different between the two cards as well.
What I am saying is that ATI sent a product out to reviewers knowing full well their board partners would be releasing slightly "cheaper" versions to retail. If Nvidia did this, Charlie and the whole Nvidia Hate Train would pull up at the station and have their way with it. I know there is no "balance" in this industry or in the minds of people but I personally think someone with both cards should conclusively test one versus the other's power consumption.
If I was one of those reviewers who received the version that won't be available at retail until XFX releases their card, I would be pretty ticked off.
XFX First to Use Premium Reference Design for Radeon HD 4770
http://www.techpowerup.com/92862/XFX...n_HD_4770.htmlQuote:
XFX continues to show enthusiasm with its ATI Radeon line of products, by coming up with the first Radeon HD 4770 accelerator for the market to use the premium reference design for Radeon HD 4770 (model: XFX 4770ST D5 512MB). AMD had come up with two choices of coolers for its partners. Most of them choose the one which is more cost-effective, so the sales margins could be improved in an already tight pricing-segment.
XFX used the premium reference-design cooler and PCB, with a major difference that it comes in black instead of red. XFX has so far had a knack of trying as hard as it can, to color its cards black. The company did so with the Radeon HD 4870 reference design accelerator recently. This card retains the reference clock speeds of 750 MHz (core), and 800 MHz (memory). Given that XFX chose the more expensive parts in making this card, it will pass on the premium to the consumer, making it slightly more expensive than the reference design cards in its league.
http://www.cpusers.gr/attachment.php...1&d=1241094297
Well, after looking at your review and Anandtech's it seems like the power consumption is the same. At idle, it's a bit worse than 4830 (~8W) but at load is better(~18W). Compared to the 9800GT it's about the same too. And I assume by what you wrote and previously written that you have a retail card.
The OC potential is locked by AMD to 830MHz, no one should be complaining about not getting to OC above that level IMO.
So maybe it's just you blowing things out of proportion?
I'm not complaining since I got a retail version. What I was saying that that people seem to react differently to ATI's flubs than they do to Nvidia's. It was more a comment about human nature rather than anything else. ;)
Since people will soon be (and some are already) using RivaTuner which can clock the card FAR above 830Mhz, it could become an issue.Quote:

Yeah, I was thinking about buying one of these to play around with, in addition to recommending them to some of my friends. This development of the lack of some hardware on the board has really turned me off to this card though. ATi, it isn't liked when nVidia does it, what makes you think it won't be minded when YOU do it? As the picture above shows, even the XFX board is missing the same hardware. No thanks.
The missing hardware (mosfets, capacitors) will make 0 difference, unless you are running LN2 and you absolutely need to run 1.6v through the card :D
I hope your right oohms, cause i just pulled the trigger on two XFX 4770's. Will probably get them end next week.
The HD 4770 uses direct voltage control to make sure the fan runs at an acceptable speed.
