    WOW! That's one big phat ugly mother of all coolers! Definitely asking for an after market job.

    Re: News - Radeon HD 5750 surfaces.

    Impressed? Not really - but I'm not surprised either. ATI seem to have some huge phobia about deviating from powers of 2 in their memory buses. Fast DDR5 makes up for some of the bandwidth limitation (and 1150MHz is pretty blazing as an *actual* memory speed...) so bandwidthwise it'll come out just ahead of the 9800GT/GTX/GTX+/GTS 250 and the 4850, but well behind the GTX260 and upwards, and 4870/90. It's raw power should be greater than all of those cards but it's hard to see it not being bottlenecked by the memory bandwidth (unless ATI know something we don't, of course - we may all be proved wrong!) Did anyone ever clock a 4850 to 4870 speeds (or vice versa) and see how much difference the bandwidth made? I'm going to have to go and serach for that now! Anyway, I think it'll have to come down to nearer £120 to make financial sense...

    As to the cooler, I'd love to know who's designing these things! Something more like the original 4770 cooler design would've been far better, but apparently big and retro is the order of the day for ATIs midrange cards...!

    EDIT: based on the graph here doubling the bandwidth (DDR3 - DDR5 in this case, 4850 v 4870 *at the same clocks*) makes between 5% and 15% difference across a range of games. So perhaps that 128bit memory interface isn't going to be such a stumbling block after all, since the 5770 has 40% more cores (read: compute power) than a 4870 / 4890. On the other hand, games can only get more intensive, so the 5770 doesn't look like a good long term purchase to me...

    Re: News - Radeon HD 5750 surfaces.

    well with the current setup being 2x DVI, 1 HDMI and 1 Display Port, that mandates a 2 slot design. That cooler looks cheap (cost wise to me) which is probably the whole point.
    See System Specs.

    Re: News - Radeon HD 5750 surfaces.

    Hmmm why isn't the cooler vented out the back.... if it doesn't need lots of cooling then go for a single wide, if it needs a double wide then why not do us all a favour and vent it out of the case...

    I have been humming and haring about replacing my ageing 8800GTS 640, as the fan bearing is starting to go, one of these 2 might fit the bill perfectly If not its certainly worth my waiting a month or so (assuming my gpu doesn't blow before then, fingers crossed) and seeing how this shakes out in the market place and what the best buy is then. DX11 certainly is a selling point, regardless of Nvidia's claims to the counter as far as I am concerned.

    Re: News - Radeon HD 5750 surfaces.

    The scores VERY clearly show this part has 960sp.

    What is 960 @ 700mhz? IT'S EXACTLY THE SAME AS 4890, which is 800 @ 850mhz.

    Both are ~1.35TF.

    You could think of it as the '4850' version of the 4890, as it has 1/2 the bw. Probably won't hurt it much though, just as 4770 wasn't hurt by it.

    I think the arch differences between these parts will be approx the same as between 4890 and 4850. That is to say, ~35%...With performance 15-20%.


    That is to say:

    5770 will be 1120sp/56tmu and 800mhz, 1.792TF.
    5750 will be 960sp/48tmu and 700mhz, 1.34TF

    Another way to look at it is 5750 is 75% of 5770, same as 5850->5870, with similar performance differential.

    Essentially, you'll have a cheaper 4890 at 4870's price, and a part that is 15-20% faster at 4890's current price with these parts. (129 and 179?)

    Bet my hat.

    Re: News - Radeon HD 5750 surfaces.

    To me the best part of this particular card is its length - no longer do I need a bloody mile-long case to house a graphics card. The current length of my 4830 should be the most I need.

    73.6GB/s seem abit on the slow side. 1.57TFLOPS sounds ok though, and it looks nice and short.

    If it costs £115 that's not worth it IMO, £95 is about right.

    Re: News - Radeon HD 5750 surfaces.

    Be nice to see if someone makes a cooler that pushes the hot air out the computer. All the 4770's on the market suffer from a single slot cooler (albiat one) which annoyed me ever so much.

    Single PCI-E power? Slim card?

    All that I need!
