Mobile GeForce GTX Graphics: Model Inflation Gone Awry

Mobile GeForce GTX Graphics: Model Inflation Gone Awry
By

Bringing high-end performance to the upper-mainstream masses, the 8800 GTS 512 might be the most exciting PC gaming product…of 2007. But rather than wax nostalgic for its G92 architecture, Nvidia has rehashed and revised it, first naming it the 9800 series, then shrinking it from 65 to 55nm for the G92b, and finally moving to 40nm for its latest mainstream-mobile variant. So far, so good!

But then came the naming games. Knowingly pulling one over on mobile gamers looking to buy the latest notebook products, Nvidia re-named the 8800 GTS 512 (in its 55nm, 1 GB trim) to GeForce GTX 280M. Today’s notebook comparison shows that this sneaky maneuver probably wasn’t necessary in order to win over performance-oriented customers, but may instead be intended to woo unwary buyers as they drop out of the desktop market.

That sounds like harsh criticism, so let’s have a look at the actual specs of each mobile processor to see how accurate it is.

The computational power might be a little lower for the mobile version than the elder desktop parts, but we’re willing to give up a little clock speed to keep heat production and power consumption at notebook-acceptable levels. What we’re not willing to give up is an entire generation of graphics development while paying for the latest “high-performance” product in name only.

To be fair, Nvidia is far from the only offender, yet we remember previous products like the Radeon Mobility 9700 (based on the 9600 XT) being much closer in performance to the desktop part from which it took its name. Indeed, the aforementioned notebook comparison even shows a Mobility Radeon HD 4850 that differs from its desktop counterpart in clock speed alone, not architecture.

Eurocom’s recent delivery of a desktop Core i7-based mobile solution gave us the perfect opportunity to see how well Nvidia’s most recent high-end notebook graphics processor stands up to last year’s desktop-performance phenomena of similar name.

    Well... how long would a lappie last with power draws of the desktop GTX versions?

    Probably not more then 30 mins :)  But that's not the point.

    Actually, if you look at the notebook it's in...you could probably cool at least a GTX 275 with same-sized sinks if you had a lower power CPU.

    :o  i never noticed this before although I've never had a laptop before. maybe this article could stoke up the the big boys in the gfx department to rethink their naming schemes :)

    will these parts crash and burn like every other previous nvidia product released for laptop over the last 2 years?

    Well, the laptop maker could always try putting in a normal Geforce card...

    It would be hard, but when nVidia makes a card using the same specs as the GTS 250...except lower clock speeds...it could at least call the thing a GTS 250M.

    Then again, both it an the GTS 250 are actually die-shrunk, underclocked 8800 GTS 512s...with twice the memory.

    I think the die on the GTX 260+ is just too large to shrink down to be cool enough and power hungryless enough to put in a laptop.

    Very well done article.... It explains the lower cost of the 280M part versus the 8800M GTX MXM addon... Interesting indeed... Especially since I own a laptop that uses the latter... That is bad on nVidia to represent the mobile part as the same model number... This does not sit well with me at all...

    Place your ATI Mobility Laptop on a decent Laptop Cooler, (Belkin make a very good one, 8/10 Degrees Celsius depending on load) plugged into the mains(Which is exactly where most people will be when gaming, Battery life does not tend to allow long bouts of mobile gaming, we are used to it!)and overclock the Mobility chipset using AMDGpuTool.exe which allows for a significant overclock!

    Check the temps with HWmonitor until you find a happy overclock versus temperature. i bet you will find it going to the same clock speeds as the desktop variety.

    I can't believe that nvidia did it again! It was bad enough renaming the 8800/9800 to the GT 200 class but to imply its now a mobile equivalent to the GTX 280 is freakin wrong! Glad TH wrote this... I hadn't heard about it yet. After their defective graphics of two years ago I didn't really need another reason to avoid their mobile line further but I was hoping they'd at least begin to prove they've got reliable parts. Now though, reliable or not I won't stand for this BS. Nvidia will never get a recommendation from me.

    you cannot expect ATI to even consider changing the name on their mobile parts unless Nvidia does it first. Nvidia has been riding this train for a while now, and in order for ATI to compete they may have to follow the trend and start "over-naming" their mobile parts. I'm sure Nvidia is NOT going to change the mobile parts' names, so the only fair thing to do is for ATI to rename that 4850M into 4890M :)  and honestly, even that would not be as bad as 8800GTS-->280M.

    ATI really isn't that bad at all actually....People have gotten scores over 16000 in 3dMark06 using Mobility 3870x2 and a mildly overclocked CPU (mildly because that's all you can do on a laptop). That is on par with the desktop equivalent if you ask me. Maybe even slightly better depending on the rig. And the fact that the architecture is IDENTICAL for the laptop/desktop parts with ATI puts me 100% at ease.

    Nvidia however, I agree is atrocious with it's naming. If anyone has the time and money, they could probably be successfully sued over this haha. Of course....in about 1 minute on Nvidia's website you can figure out the equivalent desktop GPU as well...

    Pei-chenWhy complaint? Would you prefer the sticker on your extreme gaming notebook to say Intel Core i7 and NVIDIA 8800GTS? NVIDIA renamed old parts because they need to present a unified lineup that doesn’t confuse the customer. Having a bunch of 8x00, 9x00, GTX 2x0 is not going to help customer making a purchase decision.All you have to remember is that GTX 280 > GTX 260 > GTS 260 and you know how much you want to spend. Whether the name corresponds with desktop parts is a non-issue as you are not going to substitute an 11lb gaming notebook with a 15lb Shuttle case and 20lb LCD.

    Except that GTX280M = GTS250. That's the complaint.

    At best, the top end part should be a GTX250M. This is misleading and shady as hell. Im done with nVidia, I'll never buy or recommend one of their products again.

    The problem here is that it reall isn't about the speed of the part compared to it's desktop counter part. Anyone that expects it to be close is rather foolish. The real issue here is the that the name of the mobile part has nothing to do with the archeticture the chip is designed. That is were ATI is successful and NVidia fails completely. Yes the ATI part is slower then it's desktop counterpart but atleast it contains the same basic chip design and features. The nvidia part doesn't it isn't even based on the GTX 2x0 archeticture.

    We should remember that there are allot scarafices made to get either card into a laptop and in many cases the card will vary from laptop to laptop.
