Cutting Through Mobile Graphics Naming

by

With Nvidia’s mobile solution no longer available to us when we started adding newer games to our notebook suite, we were forced to break today’s benchmarks into two groups. Performance differences in the older collection of tests were tightened by CPU bottlenecks in Crysis, while StarCraft II caused the same phenomenon in the newer group.

With a mix of resolutions starting at a unrealistically-low 1280x720, the desktop Radeon HD 6990 outpaces a pair of Radeon HD 6990Ms by around 10%. However, most readers will really want to see is how these solutions perform at a high-end notebook’s 1920x1080 native resolution.

A few folks tried telling us that CPU bottlenecks would make 1920x1080 results meaningless for pair of Radeon HD 6990M graphics modules. And still, the dual-GPU desktop card still outpaces the notebook solution by around 13% on average. And that’s with a known CPU-bottlenecked game thrown into the mix for both gaming suites.

Nvidia is only slightly less-guilty than AMD since it doesn’t give any of its mobile modules a model number equal to one of its dual-GPU desktop cards. In other words, its fastest mobile product wasn’t forced to face-off against a GeForce GTX 590. Though we don't witness the same bloodbath suffered by the AMD mobile-to-desktop comparison, it still takes two GeForce GTX 580Ms to approach the performance of a single GeForce GTX 580.

AMD rates its Radeon HD 6990 at nearly four times the power consumption of its mobile counterpart, while Nvidia’s GeForce GTX 580 desktop card draws 2.5 times the wattage of its mobile sibling. We've already heard the arguments from both AMD and Nvidia in justifying the deception: "these are our fastest mobile products, and we can't deflate the names so long as the other side is doing it too." Our assertion (and cautionary benchmark results) stand, though. Today's naming is marketing-driven, spurred by AMD and Nvidia trying to one-up each other in promoting mobile architectures, and it only continues to worsen over time. 

While the performance of these mobile solutions with dual GPUs often appears wonderful at 1920x1080, anyone who expected one Radeon HD 6990M or GeForce GTX 580M to facilitate adequate performance is going to be sorely disappointed. One desktop card can certainly shoulder those loads, though, so we remain dissatisfied with the way mobile naming continues to be handled.

"Recent invention"

Did...did this article travel forwards in time half a year? O_o

The HD 6990M is certainly the worst in a long line of ever-increasing false advertising by GPU manufacturers when it comes to their mobile cards.

Every generation is more guilty than the one before, but AMD indeed hit a new low when they used the name of their dual-GPU flagship to go along with a single-GPU mobile card. (Not even based off the same GPU at that)

I wonder what the chances of someone successfully filing a false advertising suit for this would be? Especially in the EU where they seem much stricter about that stuff than the US is, I'd have to think they'd have a decent shot. (This is at least as bad as the whole LED/LCD TV thing that the courts ruled against the manufacturers on)

I can let some reasonable under-clocking (say 25% at most) get by for mobile GPU's under the same name, but they should have to be based off the same GPU as the desktop card that they are named after at least, and in the case of using the name of a dual-GPU card they should actually have to be dual GPU cards.

Either put an actual 6990 in the laptop, or call it a HD 6870m.

What on earth took you guys so long to realize this??

This is nothing new to the laptop world and is common knowledge. You can't expect 580 or 6990 desktop performance out of a mobile 580 or 6990 solutions (note the M at the end). This article may help newcomers understand the differences between mobile and desktop gpu's.

This is something like the third article to point these problems out, but it's the first to use the desktop 6990. Tom's Hardware simply doesn't have enough 6990's for every tester to have his own :)

in Nvidia and AMD's defense there is an 'M' at the end so it's not false advertising. lol

Agreed, there is an M for a reason. It's the buyers fault for not researching. Most buyers just buy the most expensive product and assume it's good. This will teach them otherwise.

That's why the article was published :)

Agreed, in part - most savy customers understand completely that the equivalent name/name-M in a laptop is underpowered/underclocked. All unsavy customers will just think that the higher number part is better (in actual fact they are more probably thinking "pay more money get better laptop").

The real problem for AMD is that for a 'significant'? time they have used desktop-equivalent naming and just added "M". This may very well be problematic for both customer and AMD when the customer 'is justified having the expectation' to expect a dual-card design......can AMD really defend against this when they persist in sticking with the naming convention taken directly from their desktop equivalents??

I'd be interested for this to be tested out.

fun article. less informed laptop buyers should be made aware of these practices by amd and nvidia.
one thing stood out to me though... amd gfx cards being cpu bottlenecked. so amd gfx cards will perform better with an overclocked 2500k compared to a..say ph ii x4 980/fx 4100/8120 (all 3 oc'ed to 4.0-4.4 ghz)? how about crossfire? will there be some kind of in-depth look into this kind of matter, since new and more powerful gfx cards are on the way and amd doesn't seem to have cpus that can let powerful gfx cards flex their muscles. i am almost certain i am gonna get attacked/downvoted for this... but my curiosity is more than fear!!

Nvidia may not be as guilty at this point in time, but their renaming and spinning out the core from the 8800, 9800 and 250 cards was epic. Nothing like selling the same old GPU (with minor improvements) for 2+ years.

This phenomenon is quite unusual really.

Don't forget the GTX285m!

I think this kind of discussion is pointless. Of course, AMD and nVidia are guilty of misleading uninformed buyers. But the point is moot since I doubt anybody would base their PC purchasing decisions on comparisons between Desktop and Notebook cards. If they need mobility, they'd be deciding between the available mobile choices. If they don't need mobility then the desktop cards would be their concern. In any case, a notebook solution is always more expensive that its desktop counterpart, so if anything, the companies are doing themselves a disfavour by naming them the same way.

Great article, and it is the reason I am done purchasing "gaming" laptops. Gotta spend $2,000+ to have a machine with an underclocked desktop 6870 in it? No thanks. I'll just take a laptop with a fast CPU for work and build a desktop for gaming.

I don't understand why people defend this. It is a lie, one to deceive the uninitiated, call it as it is. Yes we understand the difference or we probably wouldn't be reading this article so we are not the ones being being deceived out right but in a way we are still the victims. We are victims in that the graphics industry has found a way to NOT innovate, to NOT develop truly new high performance mobile video because they have been allowed to get away with just renaming the last two generations parts. You people need to wake up.

We need more articles like this that call these companies out on their deceptions.

People aren't defending AMD/Nvidia as much as looking for reasons for why they did something that overall seemed to be bad marketing decisions. I agree about needing more articles like this.

But really... none of this should come as a surprise to anyone whom reads the last page of "Best Graphics Cards for the Money" where it has clearly been said for several months at the least that the top mobile GPUs are in the same performance tier as the Radeon 6870 and GTX 560.

Nice article. However, 6990 M and desktop represent very small number of the reality out there.
I was wondering, what would be the difference in more mainstream GPUs, e.g. GTX 560 vs GTX 560M, etc.
