On May 10, 2007, NVIDIA announced the availability of their GeForce 8 notebook GPUs through select OEMs. So far the lineup consists of the 8400M, 8600M, 8700M and 8800M series chips.[36] It has been announced by nVidia that some of their graphics chips have a higher than expected rate of failure due to overheating when used in particular notebook configurations. Some major laptop manufacturers are making adjustments to fan setting and firmware updates to help delay the occurrence of any potential GPU failure. In late July, Dell released a set of BIOS updates that made the laptop fans spin more frequently[37]. As of mid-August, nVidia is yet to give further details publicly, though it has been heavily rumored that all or most of the 8400 and 8600 cards have this issue.
GeForce 8400M Series
The GeForce 8400M is the entry level series for the GeForce 8M chipset. Normally found on midrange laptops as an alternate solution to integrated graphics, the 8400M is designed for watching high definition video content rather than gaming. Versions include the 8400M G, 8400M GS, and 8400M GT. While these GPUs are not oriented for high-end gaming, the GDDR3-equipped 8400M-GT can handle most modern games at medium settings,[38] and is suitable for occasional gaming.
GeForce 8600M Series
The GeForce 8600M is offered in midrange laptops as a mid-range performance solution for enthusiasts who want to watch high-definition content such as Blu-ray Disc and HD DVD movies and play current and some future games with decent settings. Versions include the 8600M GS and 8600M GT, and provide decent gaming performance (due to the implementation of GDDR3 memory in the higher-end 8600M models) for current games.
GeForce 8600M Series
The GeForce 8600M is offered in midrange laptops as a mid-range performance solution for enthusiasts who want to watch high-definition content such as Blu-ray Disc and HD DVD movies and play current and some future games with decent settings. Versions include the 8600M GS and 8600M GT, and provide decent gaming performance (due to the implementation of GDDR3 memory in the higher-end 8600M models) for current games.
GeForce 8700M Series
The GeForce 8700M was developed for the high-end market. Currently the only version is the 8700M GT. This chipset is available on high-end laptops such as the Dell XPS M1730, Sager NP5793, and Toshiba Satellite X205. While this card is considered by most in the field to be a decent mid-range card, it is hard to classify the 8700M-GT as a high-end card due to its 128-bit memory bus, and is essentially an overclocked 8600M GT GDDR3 mid-range card.[39] However, it shows strong performance when in a dual-card SLI configuration, and provides decent gaming performance in a single-card configuration.[40]
GeForce 8800M Series
The GeForce 8800M was developed to succeed the 8700M in the high-end market, and can be found in high-end gaming notebook computers.
Versions include the 8800M GTS and 8800M GTX. These were released as the first truly high-end mobile Geforce 8 Series GPUs, each with a 256-bit memory bus and a standard 512 megabytes of GDDR3 memory, and provide high-end gaming performance equivalent to many desktop GPUs. In SLI, these can produce 3DMark06 results in the high thousands.[40]
Laptop models which include the 8800M GPUs are: Sager NP5793, Sager NP9262, Alienware m15x and m17x, HP HDX9494NR and Dell M1730. Clevo also manufactures similar laptop models for CyberPower, Rock, and Sager (among others) - all with the 8800M GTX, while including the 8800M GTS in the Gateway P-6831 FX and P-6860 FX models.
