Apparently HP has jumped the gun and released a notebook with the Radeon Xpress 200m chipset for the current Mobile Athlon64 DTR. As can be seen here, you can customize the notebook with a 128MB Radeon Xpress 200m. However, the specs state that it's a dedicated 128MB frame buffer whereas the BTO page states that the 128MB version includes HyperMemory (ATI's answer to nVIDIA's Turbocache, for those who don't know). Has anyone heard about this GPU's performance, especially in comparison to the Geforce Go 6200? Do you think it actually has a dedicated 128MB frame buffer or does the GPU dynamically address the buffer from system memory? Strange.
Edit: I found this article (from a link from the Inquirer) comparing the desktop versions of the X300HM and the 6200TC, and according to this, the X300HM does include a dedicated 128MB frame buffer to compete with the 6200TC with a 64MB frame buffer (256MB addressable through TC). I wonder if the peformance and specs are relatively the same for the Xpress 200m GPU's.
