    Sorry I mean X1800XT Mobility 256MB

    Really though, the X1800XL 256MB GPU is only using ~50W full load... forgot where I read it but they did tests. This is just the GPU by itself.

    Well since there actually is a mobile R520 part, [size=-3]I guess Fudo got the better of Dave on this one.[/size] :lol:

    Was I the only one to look at that list and yawn?

    And then waaay at the bottom. . .

    aka 8.4lbs.

    Whee! Okay, technically "thin" doesn't *require* "light", but Whee! just the same.

    Indeed, but when was the last time you didn't yawn at the list of OEMs supporting the latest DTR monster GPUs? Dell is usually absent from the initial announcements but will likely eventually release an MR520-based system. Otherwise, the rest of the top-tier OEMs seem to be quite happy with the X1400/1600 and their green equivalents. This has gradually become more of a boutique notebook manufacturers' market segment.

    Anyone have TDP figures for both versions, not just predicted from Xbit?

    I have official confirmation of 35W TDP for X1800XT Mobility. Unsure about the X1800 Mobility, but judging from previous scores, it should be around 30-32W TDP. Waiting for the email reply :)

    Are you absolutely sure? How do you know the TDP of 35W is correct, knowing the measurements taken by Xbit Labs on the X1800XL, which is basically the same?

    ATI told me so at CES. High-end graphics TDP is always 35W for mobility.

    I'm willing to take bets again ;)

    But is that 35W at idle, 2D load, or 3D load?

    Since the X1800XL is also running at 500MHz core, but runs slower DDR3 (1.0 GHz vs 1.3 GHz), and has 57W TDP instead of 35W the MR1800XT reportedly has, what methods could ATi use to reduce the TDP so much?

    35W TDP means it's the maximum power consumption possible, aka full load.

    It's using back bias and a bunch of other cool techs :)

    PowerPlay 6.0 includes:

    Back Bias
    Dynamic Lane Count Switching
    Clock Gating
    Power-On-Demand

    Yet high-end desktop cards are over 100w? Whee, that thermal curve must be damn steep at the end! :shock:

    You also have to consider how the cards have to be built for extreme overclocking ;)

    Take a look at the 6-7 phase power on the X1900... the section dedicated on the PCB for clean power is about the same size as that of the entire Mobility X1800! (this is mostly a guesstimate based on pictures)

    Sorry to revive an old thread, but there's a rumour that Dell might be taking Mobility X1800 for a spin. :shock:

    "Mobility X1800: The #1 choice for 18lb laptops everwhere!"? It doesn't quite sing, does it? :cool:

    Tho I'm sure they'd rather have a Dell win than not, every time.

    Don't forget the MX1800 only draws 35 watts.
