ATI Radeon HD 4890: The RV790 Unveiled

Article Index:   

Performance Summary: Summarizing the performance of the ATI Radeon HD 4890, as it relates to AMD's previous generation HD 4870, is easy. Due to the its increased GPU core and memory clock speeds, the Radeon HD 4890 is the fastest, single-GPU powered graphics card AMD / ATI has released to date. In every test, the Radeon HD 4890 (Asus EAH4890) was faster than the 1GB Radeon HD 4870, and the overclocked 4890 (Asus EAH4890 TOP) simply increased the card's overall lead. In comparison to competing offerings from NVIDIA, the Radeon HD 4890 is faster than the GeForce GTX 260 Core 216 overall, but it didn't quite keep pace with the just announced GeForce GTX 275.


Exact pricing for the various ATI Radeon HD 4890 cards that should start to become available sometime later today is yet to be nailed down. According to the most recent information we have, pricing for reference clocked standard edition Radeon HD 4890 cards should be about $249, but mail in rebates should bring the final priced down to about $229. We are still waiting to confirm what AMD's add-in board partners will be selling Radeon HD 4890 overclocked edition parts for, but we're hearing $269 is the target, with mail in rebates bringing the final price down to about $249. Considering what we've seen from the Radeon HD 4890, the cards offers a lot of bang for the buck, especially if you're the overclocking type. The RV790 GPU powering the Radeon HD 4890 looks to have plenty of frequency headroom left for overclocking, which will surely appeal to the modders out there.

It is not a completely new design, but the Radeon HD 4890 is an exciting product nonetheless. To put it simply, the Radeon HD 4890 is the fastest, single-GPU powered graphics card AMD has ever produced. And its competitive pricing and overclocking headroom should further its appeal amongst enthusiasts. It may not be the fastest card in AMD's graphics card line--that distinction still belongs to the Radeon HD 4870 X2--but could a dual-RV790 GPU based graphics card be that far out for AMD? Time will tell, of course. For now, the battle between AMD and NVIDIA rages on with a fresh pair of combatants that offer value propositions that are sure to please potential consumers.

  • Strong performer
  • DX10.1 Support
  • Great overclocker
  • Relatively quiet
  • Competitive pricing
  • Not quite as fast as the GTX 275
  • We prefer lower streat prices to MIRs

I knew this was coming. I myself am even though an ATI GPU user not excited about this card itself. I am excited about the prices that will result from it's release. Both AMD/Nvidia will most likely start another price war at least to some extent, bringing prices for performance down further.

Also as per there previous actions in the GPU battle before the 3800 line they released a stand alone top end of the preceding ATI high end card (the XT2950 I think it was). Then a two or three months later they dropped the 3870/50 models. So this may be a pre cursor to some sense.

I am not saying I have any inside info on it. Thats just what I remember them doing a couple years back. I also find it funny this card is a 55nm card, just like there last one, but rumour had it they were going to 45nm for there next GPU set.

[quote user="article"]While the power consumption numbers put the 4890 and 4870 in a similar league, we can say the 4890 runs much cooler than the 4870. Our Asus Radeon HD 4890 cards idled at under 50'C and peaked in the mid 80's under load. But where we noticed the biggest difference was when we removed the cards from the test system. After testing, the Radeon HD 4890 felt very warm to the touch when removing it from the test rig, but the Radeon HD 4870 was so much hotter, it was almost too hot to handle without giving it a few minutes to cool down. Not exactly a scientific data point, but something we wanted to mention nonetheless.[/quote] I can attest to how hot the 4870s get. This is a huge plus for the 4890.

The pace of new hardware coming out is a bit overwhelming but thrilling to.Im nowhere near some of you guys ability on obtaining some of this but one way or another Im setting my goals to at least getting an i7 and a Asus board this summer and just go from there!Hopefully with a stimulas check Im suppose to get from my disability will get me started.Maybe the i7/920 and the new Asus p6 with ddr3.Ive got 2 cases one Im redoing and one fairly new one to put something in and cant wait!ITs like going to a toy store everyday when I sign on to HH and read up on all the new tech/TOYS.Hopefully this year will better than last.
