That rumored Radeon HD 5830 graphics card from AMD doesn't appear to be launching today, in spite of previous reports. Fudzilla got an update from its sources about the matter, and it now claims the product's introduction has been delayed because of the Chinese New Year.
Reportedly, shipments might be pushed back to February 20, six days after China and Taiwan transition from the year of the ox to the year of the tiger. Fudzilla doesn't expect Radeon HD 5830 cards to become available in volume until March as a result.
Last month's coverage suggested the Radeon HD 5830 will launch at $239. Performance will no doubt end up somewhere between the Radeon HD 5770 1GB and the Radeon HD 5850, which now sell for around $163 and $289, respectively. As we noted last time, $239 isn't far off from the midpoint between those two GPUs.
Right now, AMD only has its previous-generation Radeon HD 4890 bridging the gap between the 5770 and 5850. The 4890 does tend to outpace the 5770 in terms of raw performance, but it's based on an older, power-hungrier GPU without DirectX 11 support or features like Eyefinity.
