ATI Radeon HD 4890: The RV790 Unveiled

3 thumbs up

We'd like to cover a few final data points before bringing this article to a close. Throughout all of our benchmarking and testing, we monitored how much power our test systems were consuming using a power meter. Our goal was to give you an idea as to how much power each configuration used while idling and under a heavy workload. Please keep in mind that we were testing total system power consumption at the outlet here, not just the power being drawn by the motherboards alone.

Total System Power Consumption
Tested at the Outlet

Although AMD claimed the Radeon HD 4890 would consume up to 30 fewer watts at idle and 30 more watts under load than the 4870, our testing did not prove out those claims. According to our tests, the Radeon HD 4890 actually consumed slightly less power at idle and under load. The differences were minimal, however.

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.

We'd also like to mention that the Radeon HD 4890 is a relatively quiet running card. At idle, the fan on the card is barely audible over the other components in our test system. Under load, the fan does spin up and is audible over the other components, but we would not consider it loud by any means.

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.

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.
