     Socket G34: looks promising but not until 2010

    Dailytech has published some new information on the next G3x socket which will be used by AMD for certain massively multi-core processors. You may recall, they were already mentioned by this company during the presentation of the Montreal processor and G3MX technology (Socket G3 Memory Extender).


    According to our colleagues, the G34 socket will accompany the second generation of 45nm processors (the first usually used the AM2+ or AM3 if DDR3 was desired) starting in 2010. The Sao Paolo, an octo-core CPU, described as a double native "Shanghai" quad core, should be the first to adopt it and a 12 core known as the Magny-Cours should follow. Both will use the four HyperTransport 3.0 lanes, have 12 MB of L3 cache and 512 KB of L2 cache per core. In addition, the G34 should enable their embedded memory controller to support DDR3 on 4 channels.

    One interesting detail is that the 3 HT lanes being enough for a motherboard which can house 4 CPUs, the fourth could be used for Torrenza, an architecture that enables adding co-processors.



     Five GeForce 9Ms in the high end

    Yesterday, Nvidia unveiled five new GeForce 9Ms, all found in the "Enthusiast" segment as mid-level models were already launched at the Computex in early June. Even if Nvidia isn’t too clear on the subject, the number of calculation units and information published previously by certain of our colleagues enable us to guess which GPUs will be used. Of course, all are Hybrid SLI compatible.


    Curiously, the GeForce 9800M GT is more powerful than the GTS and this is something rather inconsistent with Nvidia’s hierarchy of suffixes.

    While the GeForce 9800M GTX should offer interesting performances for a mobile GPU (it does better than the 8800M GTX and its 96 calculation units), note that, for example, the 9700M GT will be much closer to the 8600 GTS rather than the 9600 GT desktop – and this despite (or rather due to) the official nomenclature. To find an equivalent to the 9600 GT, we will have to look towards the 9800M GTS and even then frequencies are much lower! Unfortunately, this is a deceptive practice that we see much too often.

    Like their smaller siblings, they can fit into MXM 3.0 type modules and their creator promises PhysX support via a beta driver starting in the third quarter. We are betting the big green graphics giant will do everything possible to not reproduce the errors made with other mobile GPUs. Moreover, more precise information on these products would be appreciated.



     Nvidia adopts Silicon On Insulator

    Logo NvidiaThe SOI Industry Consortium has announced that it now counts Nvidia amongst its members. Formed in October 2007, its aim is to promote and accelerate the adoption of SOI (Silicon On Insulator) technology by the industry.

    This technology enables reducing the loss of electrons during their movement in transistors. More specifically, it consists of insulating the transistor with pure silicon exception for a fine layer that is in contact with the transistor and which serves in conducting electrons. By joining this consortium, the firm with the chameleon logo is amongst 22 other companies including AMD, Applied Materials, ARM, Chartered Semiconductor, Freescale Semiconductor, IBM, Samsung, Soitec, ST, Synopsys, TSMC and UMC to name just a few.

    The question then arises which future Nvidia products will benefit from SOI and, all things equal in other domains, if this will lead to significant improvements for them.
