AMD To Launch Radeon HD4890 "RV790" In April

[gOJDO]

They cannot create a shader core with 1000SPs. It is 960 or 1040SPs.

Right.

[xman01]

yes it would jump to 70s, but how many games does that?
besides idle with default fan profiles, idle temps exceed that
this screen should do well, exe renamed

4890 for $199? Come To Papa !!

No, the 48x0 cards don't put out a lot of heat, amd just prevents the fan from spinning up to keep them silent which leads to high temps, you can try it out, make a profile in ccc, change fan speed in profilename.xml file to higher than default and the temps drop like crazy, so it would be possible to cool a higher clocked 48x0 at 55nm as well, they would just need to sacrifice some of the silence for it.

yea i have done it myself but its not like you can keep that on 24/7. that thing is so loud i can keep my door shut and hear it across the house. they need to start making a more practical stock cooler. if you ask my video card coolers these days look like cpu coolers from the 90s.

$200 seems too good to be true, even the 4870 released at 300.

[Bo_Fox]

$200 must be for the 512MB version, and if this "rumor" holds to be true, then it might just be a clock speed increase and nothing else (like more shaders/TMU's..).. I just find $200 a bit too good to be true if it's gonna have more shaders/TMU's, in combination with 1GB of memory. 512MB is too low nowadays, so it's nearly non-sense for chips that powerful.

[LiquidReactor]

No way that 100mhz more core and 300mhz more on the memory will give 20% more.
Which means, there is more than meets the eye.

Is it a transformer?

i would be happy if they would look like cpu coolers from the 90s, cause that would mean practically no heat and passive design.

I am willing to believe this once. Indeed, come to me baby!

[Hockeydude]

With the prices supposedly in the $200-250 range, it sounds like the 4870s will drop quite a bit in price.

You're right. I checked this news at some other sources and the price will be $249-$299-ish. x(

VR-Zone says it's going to be $250 for the standard edition and $300 for the OC edition.
I guess if the OC edition comes at that price then it should really be able to give the GTX285 a run for its money, otherwise it would be cheaper.

[Barys]

So it seems that NVIDIA will get trouble again beacuse according to rumours they won`t have a worthy GPU (price/performance/produce costs ratio) to counter Rv790.

No one knows exactly what nVidia will have to counter AMD's offerings in April.
It would make sense to go into a more efficient-per-transistor design than GT200, hence making cheaper and same-performance GPUs like they did with the G80-G92 transition.

[dan7777]

it will always go one way then the other at the moment nvidia lead the way, then amd will then overtake them, then nvidia will take over again lol nvidia much better drivers than amd so i will always go nvidia less problems in my opinion.

[FischOderAal]

When did you try an AMD/ATI card for the last time? My graphic history is as follows:
Geforce 2 MX
Geforce 2 GTX
Radeon 9600 Pro
Geforce 6800 GT
Radeon X1800 GTO
Radeon X1950 Pro
Radeon HD-4870

Never experienced any severe issues with any of them The driver might've been an issue back in the Radeon 9x00 days (I used the DNA back then afair) but I don't think it is any more, at least when you're running single-gpu.

And isn't that such a thoughtfull opinion?

[Macadamia]

Meh, the 790 is a nice performer, but still not amazing-ish in tech.


The 740... now that's nuts. The size of a 55nm 9500GT with triple the performance... notebooks?

[Macadamia]

The probability that 790 is a 40nm, with so many tries to even get 740 done properly, is slim. Really slim.

[Macadamia]

Why?

Think of 770 -> 790 as X1800 -> X1900 (I think the 20% is really, really conservative. But that's just me.)


No shrinks, just a new chip with more oomph than just clocks *cough*

GT212 won't come before Q3 09, right ? If RV790 delivers its promises, it WILL be a kick a$$ card in the market for a while -a bearish market it is.

Yes, and no.

Back when the X1800 launched, it was concluded that ATI just didn't design enough horsepower into it. Then, the X1900 series was launched, which addressed that.

Whereas here, the 4870 was, and still is a very capable contender, and the 4890 is just a response to nvidia's refresh.

Also, I wouldn't hold my breath for this being 40nm. As others have mentioned, TSMC's 40nm node has been plauged with so many issues, and I think that ATI will not want to fumble the ball here when it comes to their "highend", or forefront products.

If GT212 is needed to beat RV790 then Nvidia is in a lot of trouble. GT215 or GT214 would be a more probable competitor.

[zerazax]

RV790 sounds like the R520->R580 refresh than a new node at this point

TSMC really dropped the ball with 40nm

[ToTTenTranz]

Yes, and no.

Back when the X1800 launched, it was concluded that ATI just didn't design enough horsepower into it. Then, the X1900 series was launched, which addressed that.

I think that's what ATI already did with the passage from RV670 to RV770.

If it's not 40nm and it has no architectural changes, then I see no point at all in such a product.
The HD4870 is already consuming so much.. Unless they completely redesign the cooling system and add high-end voltage regulation to the card, I don't even think they can overclock the core another 30%.

[eddieobscurant]

I believe it's a 40nm card because if it is a 55nm i don't see the reason for the delay. At 55nm they should be able to foresee what they could and not do due to power limitations several months ago. So they could have launched the 55nm r790 at january as a response to the 285 which first benchmarks was available since the mid december, and ati already knew what would be 285 perfomance more or less and i don't believe they started r790 design after 285 was released. All that of course based on the fact that r790 is not a complete redesign on 55nm because it doesn't make much sense and either way even that wouldn't delay so much as april, since 55nm is a known process.
