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.

People don't buy vid cards to run 3dmark. It's more for "bragging rights."

Dude: "He baby, Josh is running an HD 4650...heh..I got me a 4890!"
Chick: "I have no personality! Show me your penis!"

Sigh...if only life was that simple...

It really is. Replace "4890" with "money", and "I have no personality" with "you sure there's no alcohol in this?"

Last year a friend of mine went to Fry's to pick something up and one of the salepeople was hitting on her and started bragging about his computer to her. Needless to say, she wasn't very impressed.

Ideally 3dmark is meant to act like a common measuring stick for performance. If I bought a new card I'd like to see how it fared against the reviews I looked at, 3dmark seems like one of the better options especially if I didn't have any of the games in the review.

Where 3dmark (and others) fall down is that they don't give you measurements that are universal enough for people to be able to translate them into scores for other games.

Theoretically if they were, I could run a benchmark test and be able to calculate system performance in any game past, future or present with reasonable accuracy. Not only would that make benchmarks useful but they could easily be the only performance metric you need consult prior to purchase.
