Introduction

We've stated many times before how much we respect NVIDIA for getting their parts into consumers' hands on the day of their release. We've also mentioned how frustrating it is that ATI can never seem to get their gear out on the day of "release". This appears to again be the case right now for ATI's new laptop version of the X1600, the Mobility Radeon X1600. ATI's launch partner, ASUS, will be selling the part in their upcoming A7V notebook which is launching in Asia today, but the rest of the world will not be able to buy this solution just yet.

The X1600 is a mid-range graphics solution that is meant to perform at about the same level of the X800 GTO and the 6600 GT. The mobile version will probably be a good solution for laptops, as it offers good quality graphics without generating excessive heat and quickly sapping up all of your battery life.

When ATI announced the X1000 lineup two months ago, they had planned on having the desktop X1600 out on the 30th of November. Unfortunately for ATI, this day has come and gone, and there are still no X1600s to be found for sale at the time of this writing. The Mobility Radeon X1600 (MRX1600) is officially scheduled to be released today (December 5th) in Asia with a US release scheduled for mid-January, but we aren't sure when they will really be available to buy in either region. ATI assures us that ASUS has notebooks ready to sell, but availability unconfirmed as of yet.

The Mobility Radeon X1600 is essentially the same as its desktop counterpart with the exception that it is clocked slightly lower. Here are the specifications:

12 Pixel Pipes
5 Vertex Pipes
4 Texture Units
4 Render Back-Ends
128 Max. Threads
Core clock: 470
Memory clock: 470

Compare this to the desktop version(s) of the proposed X1600 and we see much lower clocks. The X1600 XT was announced at launch to have 590MHz core and 1.38GHz memory clock speeds and 256MB of RAM. The MRX1600 is closer in implementation to the potential X1600 Pro, which might have 500MHz core and 780MHz memory clocks. The other major downgrade the mobile that mid-range part gets is in memory size to 128MB. The coolness factor comes in when you realize that ATI can pack the GPU and all of its RAM on a 46mm X 46mm square package.

As of right now, HD quality H.264 decompression takes up too much processing power to run smoothly on a PC, but with the MRX1600, ATI is promising HD video decoding in graphics hardware. This is good news, but unfortunately, neither ATI nor NVIDIA have released a driver that supports it. We feel that it's a little premature to list something as a "feature" before it's actually supported, but hopefully, we'll see these drivers sooner rather than later.

    I fully expect this chip to show up in Intels powerbooks that'll be annouced next month. Reply

    There's no way they fit the GPU die and all four of those memory modules on a package that is 46 mm^2. If it's a square, then that's less than 7 mm in each direction. That surely is a typo or mistake Reply

    Wow, very sorry ... that was a typo.

    I added that line to Josh's article. I appologize for not catching the mistake earlier.

    42mm x 42mm is still very small.

    Maybe you could correctly quote the article and not insert a space that isn't there? It isn't Forty Six square mm, its Forty Six mm squared. Like 4 sides, each side 46mm long. This is like middle school stuff here.

    P.S. - I know this answer isn't nice, but above poster shouldn't call out the author before getting his/her facts strait.

    you're a doofus if you think a space means that much. both ways to write it mean the same to me, and surely it should be corrected. Reply

    Call me what you want, but I was capable of reading it correctly, apparently that is too difficult for others. I understand the reason people are consufed, but Square MM and MM Squared are two different commonly used concepts. Reply

    No theyre not. They are the same thing. Its a typo, in a horribly written article. No comparisons of battery life etc. Oh, and that is one hideous laptop. Reply

    my god it is hideous Reply

    46 Square mm refers to 46mm².


    46 mm squared refers to the length of one side of the chip, 46 mm, which still has to be squared, giving 21.16cm².

    I disagree.

    I say that:
    46mm^2 = 46 mm^2 = 2mm*23mm
    and
    (46mm)^2 = 46mm*46mm = 2116mm^2

    Anytime you square a unit you are only squaring the unit, not the quantity. Whether or not there is a space does not matter.

    Yes one could figure out what the article meant, but that does not make his point invalid.

    Also, people have sided against you, because you are the only one defending the way it was written and people have dropped your score from 2 to 1.
