Power Consumption

When it comes to power consumption, the Radeon HD 4670 is nothing short of awesome. At idle our entire testbed (Intel G45 + Core 2 Quad Q9450) used only 67W with the Radeon HD 4670. Under load running Crysis we were looking at 139W.

While the 9500 GT is a little lower in power use, the performance difference is huge as well. The 4670 drawing 139W competes in performance with the cards that draw about 30W more.

The card isn't passively cooled, but it is fairly quiet. For those who don't need absolute silence and want an HTPC that doubles as a gaming machine on a 720p TV, the 4670 might be the ticket.

    On top of that, the 4650/4670 appears to be the perfect choice for SFF and HTPC builders. The low power requirements and lack of PCIe power connector make it perfect for sub-400 watt power supplies. Other reviews around the web have mentioned that the fan on the reference card is very quiet. I wouldn't be surprised to see a fanless "silent" option for the 4650 soon.

    I'll probably put one of these in my Shuttle xpc, as it seems more than capable of 720p gaming.

    I'm with Derrick here, and would rather have an NV 9600GT. That is actually what I own now(an eVGA double slot 9600GT with rear exhaust). It uses about 18W more idle, 20-25W more while gaming, and it is roughly twice as fast as my old 7600GT. Above measured with a kill a watt power monitoring device at the wall.

    I guess that the better experiences I have had with NV parts,and the fact that I have owned mostly NV parts in my personal systems(since at least the late 90's) has made me at least slightly partial. I must admit that this card does look tempting, and if I had not just bought a 9600GT, I would give it some consideration. One thing for sure though, what ever I bought from this side of the camp *would* have to be made by Sapphire . . .

    There is also another factor to consider. HD4670 does not require any external 6/8pin PCIE power connectors, which makes it more ideal for people with older or OEM power supplies. Otherwise I agree with you on this that 9600GT is still a very viable and competitive alternative.

    The main issue I have,.. you used a price for the 3870 that is about 1 year old now,.. $199 which a casual reader would then infer that the 3870 is a worse price/performance pick,... if you are going to use september 2008 prices for the other cards,.. use September 2008 prices for the 3870 so you can paint the picture on a more level playing field. That adds to the reader's ability to see what price/performance to choose from.

    Otherwise, my feelings are, at least we have some benchmarks for this card. I am a bit disappointed since it is so pared down from the 4850/4870 in areas, which makes it unable to really compete in some ways with prior generation for similar price.

    in the text of the article i mention that you can find the 3870 for ~150 ... which reflected the majority of what i saw on google yesterday.

    today i took a look and i can now find plenty of 3870 hardware for ~$120. which is much closer to the $100 price of the 9600 GT.

    But I'd still pick a 9600 GT over a 3870 at those prices, so it really doesn't change the recommendation.

    Call me blind but I read through the article twice and I didn't once see a $150 price point mentioned for the 3870. If I just missed it point it out to me please.

    While you're at it go ahead and take a look at this. As you mentioned in the article, shop around.

    I've gone ahead and added a "Current Street Price" line to the table to help put things in perspective. Prices at the time of writing were grabbed from Newegg.

    Any overclocking potential on this card?
  • AssBall - Wednesday, September 10, 2008 - link

    I would also be interested in this, as my 3850 seems to overclock nicely, and 10% more performance out of a budget card is very nice if you can swing it.
