NVIDIA's GeForce 8-series goes mobile

NVIDIA announced its mobile DirectX 10 lineup consisting of the GeForce 8600M GT, 8600M GS, 8400M GT, 8400M GS, and 8400M G. This time around, NVIDIA has abandoned the “Go” prefix of previous generation mobile graphics processors in favor of the new “M” suffix. The new mobile lineup features unified shaders, PureVideo HD and PowerMizer power saving technology.

The new GeForce "M" lineup launched simultaneously with Intel's Santa Rosa Centrino platform.  Although NVIDIA claims it does not compete with Intel on this segment, the company is quick to note the features of its GPUs over the integrated Intel X3100 graphics found on new Santa Rosa notebooks.

"Coinciding with yesterday's official launch of Santa Rosa, we rolled out our GeForce 8 family of notebook GPUs," stated NVIDIA CEO Jen-Hsun Huang. "The new GeForce 8M-series notebook GPUs are the first to support DirectX 10 and 1080p decoding of full HD movies."

However, even with the promise that GeForce 8M-powered notebooks are on the way from Acer, ASUS, HP, Toshiba and Samsung, there are no shipping 8M products today.

At the top of NVIDIA’s GeForce 8M lineup is the 8600M GT. The GeForce 8600M GT is the only mobile DirectX 10 product to have 32 stream processors clocked at 950 MHz. NVIDIA clocks the GeForce 8600M GT clock at 475 MHz and pairs it with 1.4 GHz memory on a 128-bit memory interface. Notebook manufacturers are free to equip the GeForce 8600M GT with up to 512MB of video memory.

Slotting below the GeForce 8600M GT is the 8600M GS. The GeForce 8600M GS has half the stream processors as its GT counterpart. NVIDIA clocks the stream processors at 1.2 GHz to make up for having less shader power. The core clock is raised to 600 MHz as well. Memory remains the same – up to 512MB of 1.4 GHz memory on a 128-bit memory interface.

On the value-side of things is the GeForce 8400M lineup. The GeForce 8400M GT features the same 16 stream processors as the 8600M GS. However, the GeForce 8400M GT has lower 900 MHz shader, 450 MHz core and 1.2 GHz memory clocks. As with the GeForce 8600M GS, the 8400M GT can have up to 512MB of video memory on a 128-bit interface.

In the middle of the GeForce 8400M lineup is the 8400M GS with 16 stream processors. The 16 stream processors have a lower clock of 800 MHz. NVIDIA clocks the core at a slightly lower 400 MHz while memory clock is set at 600 MHz, as with the GT model. However, the GeForce 8400M GS can only have up to 256MB of video memory on a 64-bit interface.

At the very bottom of the new GeForce 8M lineup is the eight stream processors endowed GeForce 8400M G. This model is virtually identical to the GeForce 8400M GS except with half the shader power. Core clock remains at 400 MHz, as with the 800 MHz shader and 1.2 GHz memory clocks. Manufacturers are free to equip GeForce 8400M G with up to 256MB of video memory on its 64-bit memory interface.

Huang was not shy to talk about the company's upcoming Intel IGP chipset, MCP73.  Again, while NVIDIA CEO Huang reinforced the notion that the company is not competing with Intel, he confirmed the MCP73 will have mobile offerings.  Recent documentation claimed MCP73 for the desktop could launch as soon as June 2007.

Lets see some benchmarks and justification to upgrade. We dont need DX10 yet, so the GO 7900 or 7950 is still the best option for performance users

not true because im currently on my m1710 with the 7900 GS and company of heroes is not fast as my 8800GTX and considering the 8600 GTM is better than the 7900 GX2 and is DX10 compatible why isnt it the best for the mobile market today

WTF? How can you even compare a GO (and i mean mobile) GO 7900 GS or GO 7950 to a desktop 8800GTX???

Are you mad?

If you're trying to tell me that the 8600M GT can beat a GO 7950GTX mobile GPU then youre also mad!

BTW, I never knew Nvidia released a 7900GX2?? lol

The only advantage of these 8xxx series mobile chipsets right now is the DX10 and H.264 enhancements.

3dMark06 benchmarks around the net still suggest the GO 7900 and above mobile video GPU's are faster than 8400/8600M mobile equivalents.

You only have to compare the Desktop equivalents (7600 vs 8600) to get a grip on the fact that the 8600 aint much quicker than the 7600.

yea u r i was totally wrong there is no GX2 go and the 7900 GS is sort of faster than the 8600M GT

doesnt matter to me the 7900 GS go is on my laptop as my secondary pc when my main 4GB 3.6ghz 8800GTX Xfi needs a long term maintanence (1 week RMA)

Eyes Intel?

Where is that phrase justified?
From reading this news clip, it appears that NV stated themselves that they arent competing with Intel.

We know they are here. But still, what portion of this news warranted the "eyes Intel"?

If its due to this new part, they've always competed with Intel mobile GPUs. So they eyeing would exist already, thus be strange to repeat if NV had been eyeing Intel all these years?

If its because NV was supposedly "quick to point out its improvements over the latest mobile Intel GPU", then I still fail to see how they werent "eyeing" Intel prior to the GF8M launch..

Just curious. That was my only thought after being finished reading this..
Otherwise, this looks like a great mobile part on the way. Pretty tough to knock anything Nvidia these days. Can't go wrong. I doubt this will be any different.

I'm thinking NVIDIA is sort of playing "wait and see." The ATI buyout by AMD caught them totally off guard, and NVIDIA was getting ready to put the hammer on Intel.

Fact is, though, that if NVIDIA starts going after Intel's centrino clients, they will end up with with the same amount of marketshare they have now in IGP notebook sales: 0%.

Confusing Marketing

I don't understand why they clock the crippled 8600 GS so high when it's supposed to be the inferior product. It makes much more sense for them to clock the GT much higher and then clock the GS, with its smaller amount of shaders, slightly below that. It just seems like nVidia's not differentiating enough between the two products to make it worth going with either one.

Simple - thye need a product for every $20 segment.

My next laptop

Will be quad-core (amd or intel?), and either an 8800M or R600's top mobile variant. And I can't wait!

My question is why didn't nV release the mobile 8800 yet?

I believe it was because of the fact G80 is on the 90nm process and dissipated too much heat and is power hungry.

Its interesting to note that in more detailed benchmarks showing the 8600 GTS vs the 7950 and x1900 pros in current DX9 games. When looking at the minimal fps the 8600 GTS were consistently better at 1200x1024 resolutions and below. Max FPS of course goes to the x1900s consistently but the 8600 maintained slightly more fps at the minimum. Sometimes average FPS don't tell the whole story.

Once the shader intensive DX10 games see the light of day, the balance will likely lean in favor of the 8600 GT vs 7900s and x1900s.

I wouldn't mind having settling for an 8600m in a notebook, but why bother since vendors have already slated that NVidia will have a gamers DX10 mobile chip before years end.

I'm still running an Nvidia 4200go in my notebook, look forward to what becomes available spring of next year.

I had e-mailed R&J Tech ( as I want to upgrade my D900 K laptop and they noted they are expecting to get the cards in late June, so they're not too far out for purchase (for those who still have a Clevo system).

Very useful for those looking to build their own laptop. Just not looking forward to the price. MXM cards are not cheap.
