Sapphire spruces up HD4850
SAPPHIRE TECHNOLOGY has shipped two new models of the HD 4850: the HD 4850 1 GB and the 4850 Toxic Edition. The HD 4850 1GB, essentially an upgraded variant of the original HD 4850, offers clock speeds of up to 625MHz (core) and 993MHz (memory).
The Toxic card, fitted with 512MB of high speed memory operating at 1100MHz, is capable of achieving core clock speeds of 675MHz. Toxic also features a Zalman heatpipe fan that provides efficient cooling with a minimal amount of noise.
Both models use the PCI-Express Gen2 interface and includes dual connectors for CrossfireX cables, which allows two or more cards to function simultaneously on a CrossFireX compatible mainboard. In addition, the new cards offer improved memory management architecture and an upgraded video hardware for smooth decoding of Blu-ray, HD DVD and Mpeg content.
Sapphire has also included a dedicated HDMI adaptor that delivers both audio and video output on a single cable for direct connection to an HDMI ready display. ยต

Say what? That is standard on any HD 4800 series card! Am i missing something?

The original doc on sapphiretech.com says:
All SAPPHIRE graphics cards in the HD 4800 series incorporate the latest [...]
That Zalman cooler probably costs more than a standard double slot cooler, yet whats it's point ? Sure it'll be quiet at first but once those 160 watt start dissipating inside the case it won't be very cool at all.
That is why you should have adequate air flow through your case...
facts straight....its max thermal is 110w...its a 48"50"...not a 4870. The Zalman is excellent and knocks 30+c off the core temp at stock clocks vs. the single slot cooler other 4850's come with....yeah I said 30c. How do I know ? I have a 4850 and changed out the stock cooler to a Zalman...also boosted the core to 675mhz and it still idles under 40c vs 63c for the stock cooler at 675mhz....
Hey Ed, of course it's cool at idle no matter how much you OC, since at idle it runs at the preset low speeds, you can OC to 900MHz and it would still show the same temperature.. at idle.

And yeah this wasn't an article but a press blurb and the decoding bit is the standard 48xx PR statements.
Also the 'the standard edition runs UPTO 625/993' is nonsense of course, you can OC it like any HD4850.
