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
