Chipset AMD790FX even for DFI

The Taiwanese DFI, a company specializing in motherboards for the public pot users enthusiast, presents its own new solution based on Socket AM2+, then addressed the matching with AMD Phenom presented formally this week. Talk model LANParty UT 790FX-M2R solution based on AMD 790FX and south bridge SB600 that integrates 3 Slot PCI Express 16x mechanics with which to configure setup CrossfireX with 3 video cards in parallel. This technology has already been submitted by AMD, but is not yet available because the driver CrossfireX will be presented only during the first weeks of 2008.


In addition to 3 Slot PCI Express 16x are 4 slot modules DDR2 memory, 3 PCI slots and 1 slot traditional PCI Express 4x. The power circuitry implemented by DFI for this motherboard provides a structure with 6-way PWM dedicated to the processor, with an additional seventh specifically dedicated to the north bridge: this allows, according to what is stated by the manufacturer, to ensure greater stability of operation when the processor is overclocked.


One of the ancillary features of this motherboard is the integration of a secondary heat sink, called Transpiper, which allows to better dissipate the heat generated by components and captured by dissipatori heat mounted on the motherboard. Through a structure heatpipe, in fact, heat is moved towards this additional radiator, mounted so as to be positioned near the rear fan ventilation of houses.

Additional information is available on the DFI website at this address.

The first indiscretions on ATI R700

The website Fudzilla has published a number of articles that provide preliminary information on what should be the specifications of the next generation of video chips top range of AMD, marked with the code name of R700. This new generation of video architectures could take the name of Radeon 4000, with obviously versions aimed at different market segments depending on the cost of purchasing cards. The GPU R700 will be built with production technology to 45 nanometers, and will be combined with each other on various cards depending on the computing power required. Put simply, then, R700 should introduce the concept of core in the mini world of GPU, with card entry level segment that integrate a mini core, mid-range solutions with 2 minicore and high-end cards with 4 core.

It is clear that the differentiation between products will not only vary with the number of core but with the clock frequencies, which will presumably vary depending on the market positioning of cards. Such an approach seems to be realistically feasible for video cards: modern GPU nothing more complex structures that are parallel with stream processors that each operate independently as processing unit somewhat simple but very fast.

Each mini core should support the API DirectX 10.1, but it is not clear at the time how the various mini core will be networked together on the cards. For each of these core will be connected to a memory controller, presumably increasing complexity of the number of mini core mounted on the same day, with the possibility to use a bus to 512bit amplitude as that already seen in ATI Radeon cards HD 2900 XT.

Information about R700 are currently quite low, since the debut of this architecture does not happen before the second half of 2008. If confirmed, with a mini-core approach allows AMD to focus development on a single architecture, riadattandola then in the various market segments more simply mounting on the same core Die obtaining and, in so doing, GPU-end entry level, mainstream and top range.
