ATI Radeon 4890 shows its face

DailyTech has been able to "acquire" an ATI Radeon HD 4890 video card from one of our sources. Although we don't disclose names in order to protect our sources, we are able to say that the card arrived from Taiwan.

The Radeon HD 4890 features the RV790 core, which we are able to confirm runs at a core clock of 850MHz. We have heard that it is capable of more, but that will be up to individual board partners. The chip is not just an overclocked RV770, as there are a few tweaks and modifications that we are still investigating.

The card also features 1GB of memory via eight GDDR5 chips from Qimonda, which declared insolvency in January. The reference card we have is set to 3900 MHz effective, and we expect most of ATI's board partners to do the same. This provides 124.8 GB/s of bandwidth.

Samsung could emerge as a source for GDDR5 chips if Qimonda is forced to halt production. It recently announced 50nm production of GDDR5 chips, which it claimed was capable of 7 Gb/s.

Pricing and launch dates are still being adjusted at this time. AMD recently tried to lower prices on its Radeon 4870 and 4850 cards, but its board partners believe that the performance of the Radeon 4870 is too good  to lower prices further.

The Radeon 4890 will probably be priced moderately above the 4870, but still far below NVIDIA's GTX 280. The GTX 280 should not be confused with the mobile GTX 280M part, which is actually a rebadged GTS 250/9800 GTX+.

There are new drivers coming out next week that will have increased performance for the Radeon 4890 cards, which will invalidate all current benchmarks that have leaked out

More details will be unveiled next week at the Game Developers Conference. DailyTech will be testing the card this weekend.

Telling the truth is fanboism?

Says more about you than anything.

Shame, it must suck being an Nvidia fanboy, must lead to a lot of unnecessary stress.

Cos you know that ATI has Mobility Radeon 4850's, 4870's and 4850X2's right?

But hey, you or I will probably never own any of those so it doesnt matter. In fact, I own an Nvidia card right now, but I just wanted to point out that your fanboy bias led you to ignore ATI's mobility radeons. Have a nice day, hope you dont froth at the mouth.

As for me, the last thing nvidia made 100% worth it was the 8800 series... (I have one of those, pretty old by today's standards).

But if I were to switch my vid card again, I'd go with an ATI again. They are simply much better at the same price point.

8800GT is like the 9700pro was. Just way ahead of the game.

I jumped on the 9700pro right away, Missed the boat on the 8800GTX, but got the 8800GT as soon as they came out and the cards still a great card, well other then the fact I had to get aftermarket HSF for these.
