Power & Temperature

Since AMD isn’t doing a reference Radeon HD 5830, non-performance data is of limited value. Even with the variety of cards among AMD’s partners, the power draw of the 5830 cards should be within a few watts of each other and vary only with the difference in their fans so long as they use a 5870 PCB. On the other hand temperature data is going to heavily depend on the cooler used, and noise data is completely useless here since it entirely depends on the cooler used.

So we have power and temperature data for you, but please keep in mind that this temperature data is really only useful as a frame of reference – retail cards could be quite dissimilar.

At idle, the power usage is just as AMD promised: it’s a hair under the 5850, by a single watt to be exact. As far as high-end cards go, this is the least power hungry among them when idling.

Under load the story is quite a bit more interesting. We know the 5830 is rated for a TDP between the 5850 and 5870 that’s much closer to the 5870, but the power draw doesn’t reflect that. Here it’s 17W over the 5850, and nearly 70W off the 5870. We’ve double checked and the card isn’t throttling (a very possible situation given the higher voltage used) so we’re not quite sure what to make of these results. The 5830 is apparently more alike the 5850 than the 5870 when it comes to power consumption, which is certainly a good thing since it means it edges out the 4870 and 4890, and is well ahead of the GTX 275.

With an eye on the fact that this temperature data is going to be heavily dependent on the cooler used, for our sample card we certainly have some interesting results. Under idle this is the coolest of our high-end cards, which is no surprise given the use of the 5870’s big cooler and the lower idle power usage of the 5830. On the other hand under load, even with the otherwise minor difference in power draw compared to the 5850 and the bigger cooler it’s 5C hotter, which is actually more in-line with what we would have expected. However it still stays below the 4800 series and the 5870, both of which get warm enough that they really have to rev up their fans.

It’ll be interesting to see just how good the vendor coolers end up being. With the relatively low load power usage, the 5830 doesn’t have to be a particularly loud card.

    Are you kidding Anandtech? Who in their right mind would buy a 4870 over a 5770? Hell, they're pretty much even in performance, and the 5770 possesses more features. Reply

    Not to mention they're so quiet and their low power consumption allow upgrades even on a weak PSU. Reply

    Nope, AnandTech's last great review of something (by that I mean intelligent and unbiased) was the review of the Phenom II X4 920 and 940. I applauded AnandTech for that on other boards because AnandTech didn't drink Intel's kool-aid at the time. AnandTech didn't do the idiotic thing like other sites and compare the Phenom II X4 to the i7. No, AnandTech did the RIGHT thing and compared it to the Core 2 Quad Q8200 and Q9400 (I think those were the Q #'s). That was the day I REALLY got into reading AnandTech because all other sites were left in the dust. I also applauded AnandTech for having the balls to point out that the GTS 250 was just a rebranded 9800 GTX+ regardless of the consequences and even posted Charlie's article about it. Those were the days when AnandTech was the best review site I'd ever seen. Those days are unfortunately...over. Reply

    long reader of anandtech but with this article for me you have lost all credibility, am not a fanboy, but it has become so obvious

    for once AMD is executing like a clock, it is not their fault that there is no competition (but maybe you can blame them for that as well) and they can charge premium on their products

    if they renamed and offered 4790 as 5830 might have pleased you but then it might not as it would come from wrong company

    won't be checking this site that often anymore, will try to time it with Nvidia releases, have a nice day

    Ho ho ho, I see what you did there

    Actually, I don't, this is just retarded

    It seems that Anandtech takes pride in using outdated Catalyst drivers to run their tests here. It is a shame that they are too lazy to re-run the tests with newer drivers.

    It is a deception to its readers/members to use HORRIBLE drivers and attempt to use the results as an indicator of the ATI card's performance. None of you should listen to any of these results because Anandtech nor Guru3D can be trusted.

    You will see the other websites with reviews on the 5830 actually use the 8.703 and 10.3b drivers ---> All all ATI cards!!!

    Shame on you Anandtech for misleading the community and public. How much is Nvidia paying you? Your results don't match ANY of my results with the 5870. You are a bogus reviewer!

    Haven't you figured it out? nVidia isn't paying AnandTech. It's Intel that's behind this. AnandTech has been Intel's pet puppy for almost a year now. The idea isn't to hurt ATi for nVidia's sake but to hurt AMD for Intel's sake. Just read any Intel review and I swear that AnandTech sounds like they want to date that criminal organization the way that they coo and fawn over everything Intel does. Reply

    Yeah so because they used older cards for the RV770 chips which more or less don't profit from new drivers at all (didn't read anything in the release notes and didn't noticed any performance gains with my 4870), the 5830 didn't perform as well!

    That's absolutely logical! I mean the bad karma of old drivers - for other cards - just horribly disturbed the 5830 and that's why it ended up, being.. as bad as in the 3dguru review :(

    Send me a test rig and a 5830 and I'll give it a go ;) Reply

    I wouldn't be willing to spend a pennny over 150 for this card; and I feel that's generous. The GTS250 was going for 110 for a while; and this card is only a little faster. It has DX11, which is a requirement at this point in time, and not a feature. And it is faster, but only to the amount that I'd expect this far into the future; in relation to the GTS250. In other words, it's the same class card, but for some reason it's selling for over twice as much; that's just stupid. I understand price drops got out of hand last generation; which is why I say 150. Really, excluding the 5850 and 5870 I'm really really disapointed with the performance of the 5000 series. Reply
