AMD breaks through 1GHz GPU barrier

AMD breaks through 1GHz GPU barrier

AMD has broken through the 1GHz barrier for the first time with its RV790 GPU. It has now released a factory overclocked version of the Radeon HD 4890.

When AMD launched the Radeon HD 4890 graphics card, it made some big claims about overclocking and, if we're frank, we came away a little disappointed despite the impressive overclocks we achieved – they just weren't up to the level AMD had claimed.

AMD has now announced an overclocked version of the Radeon HD 4890 which ships at 1GHz using "standard air cooling solutions".

At this speed, the Radeon HD 4890 can achieve 1.6 teraFLOPs of compute power, which is quite a bit more than any of Nvidia's competiting single-GPU solutions but of course not everything is equal.

Sapphire, XFX, Asus and PowerColor have announced pre-overclocked variants, with Sapphire's featuring its Vapor-X vapour chamber cooling solution – we'll have a review of this card very soon as it's currently sweating its way through our benchmarking suite.

"At 150MHz above stock speeds, this card will unlock new levels of performance and allow gamers to push t he latest DirectX 10.1 titles to new highs in image quality and frame rates," said Adrian Thomson, Vice President of Marketing at Sapphire.

XFX claims that there's even more headroom above the stock 1GHz frequency. "Hitting 1GHz is an amazing feat, even more so when done in production-level volumes and with overclocking headroom to spare," said Eddie Memon, Senior Vice President of Marketing at XFX.

It'll be interesting to see if there is additional headroom above the lofty 1GHz default clock. In terms of pricing, AMD hasn't revealed how much of a price hike we can expect, but we have pressed the company for pricing on this uprated part. Once we know, we'll let you know and we'll have to wait to see if it delivers good value over and above what's already out there. For now though, you can discuss AMD's landmark in the forums,

I honestly thought this was a bumped thread from ages ago, just read the title!

EDIT: Either i've been ninja'd or I missed the GPU part. :p

Really want to see what that Vapor-X card is like.

How are temps going on it? If they're about equal to the non-OC stock card... or lower... I want one. :D Oh, needs to be fairly quiet, too.

Or they could quite quoting GHZ like they always told intel wasn't important and just make a faster card...

I think they're trying to do that with RV870? New architectures don't just pop out of nowhere. RV870 was likely in development before the horror that R600 was, was released.

And if this is overclock scales well... well that's nVidia's GTX285 dead and buried as 'fastest single GPU card'...

These are really going to all need aftermarket coolers because even at stock speeds the 4890 cooler sounds like a hairdrier.

the saphire 4890 atomic is a stonking card....but will have a price to match and latest i read is it'd be limited edition

... you do realize the issue with your statement, right?

From the looks of it the powercolor and Sapphire cards both have aftermarket coolers.

It should be interesting to see whether these cards have any further overclocking potential or whether the 1ghz is pretty much the limit for the architecture (I assume the cores used on these are speed binned for the highest clocks with ones not able to reach 1ghz left for the standard HD4890?).

4770s in Crossfire FTW!!!! They could easily destroy 4890 @1GHz :)

Right up until the run out of memory........ or CF doesn't scale properly.

(although at lower resolution settings without lots of AA/AF they do seem to fair quite well).

they are really going for gtx285!

I've always wondered how they can call it overclocked when it comes from the factory that way?

I suppose it's easier to say it's overclocked than to give it a new name or something. It's technically overclocked if it's the 'same' product but has been made to run at a higher speed than the stock SKU.

I like how AMD has been responding to competition in the GPU market in recent times.........

For me, it's ATI not AMD, because AMD is still sinking :p

Yes! This is excellent. From a review on Hexus and OCClub, it's only a few fps slower than a GTX285. If I had the money, this card is where I'd put it.

Pedantics: Shouldn't it be 'hit/reached the 1GHz barrier' rather than 'breaks through the 1GHz barrier'? Seeing as it is exactly 1GHz.. Never mind

don't count on it, the new card is going to put out an insane amount of heat.

ATi might be on a good way there. Let's wait for the next generation of cards and see what nVidia, ATi and Intel [I still think Larry will be interesting from the mid-market section downwards] have up their sleeves.
Xir 14th May 2009, 21:32 Quote
well the standart 4890 is about 2/3ds the price of a GTX285...so there's headroom for a version that is about as fast as a GTX285.

And to the ones that say, well a CF-SLI setup is faster...a single core GPU is less prone to...complications.
And usually uses less power :D

ehh my 2 4870 1gb in crossfire plays all the games I enjoy at max settings with decent frame rates on my 30" so Im holding off upgrading until DX11 cards show up but still awesome AMD/ATI keep at it :)
Xtrafresh 15th May 2009, 10:22 Quote
this is very good for me. the 4870s are worth less and less, so soon i'll crossfire mine :)

Yeah, I know. But the Vapor-X system has been good in the past for reduced temps with quieter operation.

Hell, the Vapor-X 3870 was single slot, but was still cooler and quieter than the stock cooler...

Overclockers have one of these up for sale already (albeit pre order item) - XFX black edition. Its just shy of £230!

Given they have the normal HD4890 for <£170 I would say its overpriced.

wonder if we will eventually GPU GHZ greater than cpu GHZ? Even on par would be cool.. 'I have a Phenom 2.5ghz quad core and two dual core ati 2.5ghz cards' would be awesome... mmmm 8 cores for F@H

ya maybe but ATI tends to be pretty good at getting their cards cool with a more silent solution then what typically nVidia is known for, lol I remember back in the day with those FX cards, man those suckers were loud and sound like a dentist drill lol.

Actually ATI cards can stand a lot more IIRC they actually generally run hotter.
