With a TDP of around 61W, Sapphire is reaching an upper limit on what passive cooling can do in a still-air environment.  Any more, such as a passive cooler on the 5750 (86W TDP as standard), would require significant engineering of the cooler and heatpipes to keep it passive - such as the dual slot Gigabyte HD5750 Silent Cell, which is a passive 5750, but has a massive cooling and heatpipe arrangement, as well as a 6-pin power requirement.

Featuring stock HD5670 clocks of 775MHz core, 1GHz memory (4GHz effective), 400 stream processors and 1GB of DDR5 memory, the HD5670 is marketed as the fastest silently cooled graphics card ‘available today’ - though we can’t find it on sale yet, and the Gigabyte 5750 Silent Cell is on sale, under it's code GV-R575SL-1GI.

The HD5670 Ultimate isn’t necessarily aimed at the HTPC market, as it isn’t low profile, but we could see a use in larger ‘HTPC/Home Server’ combinations, as well as mainstream desktop computers, and gaming machines, where silence is a large part of the build.  We expect the HD5670 Ultimate to retail around $125/£95, which is at a slight premium over the majority of the current HD5670 cards available.

    is this worth it?

    if you want something to game, can it really deliver,
    and if you just need something to play blu-rays, won't something cheaper do the job just as good?

    If you thinking of a HTPC anything from the 5550 and up will do all the AVIO stuff.

    If you wane play games I would prefer card whit a silent cooler like some of the HIS models, as how nice a passive card is it also heats up the rest of your case, and whats the point of a passive card if it makes your other fans go faster and make more noise

    "the HD5670 is marketed as the fastest silently cooled graphics card ‘available today’"

    I think Powercolor might have something to say about that, with its passively cooled 5750 Go! Green: http://www.newegg.com/Product/Product.aspx?Item=N8...

    I don't doubt that Sapphire's passively cooled 5670 is a decent card, but they're stretching a bit on the marketing here.

    I have a distinct feeling they'll change it to 'fastest silent single slot' in the not too distant future. The Go Green and Silent Cell 5750s are both dual slot, meaning Sapphire can find it's marketing niche. Chances are that they know about those cards, but maybe (a long shot) marketing have decided that 775Mhz on the 5670 is faster than 700Mhz on the 5750, despite the SPs being 400 and 720 respectively.

    I guess they'd technically be right if they want to claim it has the highest clock speed of any silent vid card... F***ing marketing!

    No mention of the powercolor equivalent? How will this differenciate...

    Also, ripping Napster Logo is a bit lame...

    I have an eVGA GTS 250 with an Arctic Cooling Accelero passive cooler on it running Folding@Home 24/7/365. Cools about 20°C better than the stock cooler with very little air flow in the case.

    This is a nice single slot solution, but if you have two slots to spare, there are much better alternatives for completely silent cooling.

    I also have an Accelero on my HD4890, and it works great. I do keep a slow, silent fan strip-tied over the heatsink to keep it a little cooler, but it would do OK without that. For all intentns and purposes, it is completely silent. The only issue I had was that the Accelero didn't cool the VRMs, so I had to buy a separate heatsink for that. Reply

    I'm a little confused here.

    The ATI 3870 chip from a few years back, apparently had a TDP of 105 Watts, but Sapphire also made that card with a passive cooler.
