The gradual extinction of dedicated discrete northbridge
Until x86_64 on the desktop, the chipset on the north side controlled the RAM bus (FSB), AGP video bus and PCI bus system.
The shift in production by 2003 AMD integrated the memory controller in the microprocessor and communication via the HT bus, PCI Express PCI relegated by serial bus and AGP x8 disappears also starts to be integrated into the motherboard GPU (IGP) introduced in the northbridge by passing control to the VGA port, DVI and HDMI.
Southbridge is assigned to PCI, IDE, S-ATA, USB, audio, COM, LPT, PS / 2.
Fusion APU in 2011 once again innovate to AMD (as in 2008 when he rode two die DualCore Intel for Penryn launched AMD quadcore and 4-core Phenom monolithic) GPU integrating in the same package that contains the 2 or 4 CPU cores and integrating the northbridge itself is thus only a southbridge-Hudson is his name on the mainboard, and the APU holder: CPU, IGP, BMI, chipset communicating with HT RAM and ports IGP graphics for the PCIe 2.0 also commands North Bridge integrated into the APU.
The graphic execution speeds are increased TDP and power consumption drops from 32/40 nm chip current and recent generation RadeonHD 6500.
Intel anticipated the merger in 2010 with its Westmere and Arrandale but not yet integrated the chipset and Sandy Bridge now in the mainboard chipset P67 upper-middle range of micro override the IGP graphics output and do not allow preventing the use of improved resources renderer and low watts dissipated.
Chromebooks: portability Google
chromebook
And yes, who could doubt at this point this would happen. What do we mean? In the new commitment of Google to an extension of the markets it seeks to control and an extension of their interests. Is that if you do this, we are behind, and if it does, you lose all the gains so far. Risk-keyword if any in our day-then the strategy is smarter than Google can take.
We refer more precisely to Chromebooks, the new way Google has managed to enter the portable market. We have already said something about this blog, but on the occasion of the conference which has Google as the center of debates around the world conference is taking place these days, can not but speak of it again.
As is known, Chromebooks are computers that have instant start and are focused on work in the cloud just lit, not ever cut the connection. As for the application system, say that all will run from the browser. In this operating system achieves its greatest uniqueness.
But this is not the only way to store applications, because they want to use the old way do pdorán storing local applications using certain technologies HTML5. Read more
Intel Sandy Bridge microarchitecture / Vision Zambezi (AMD Bulldozer)
The next January 5, 2011 the Kings have a successor to Intel Nehalem / Westmere, Sandy Bridge models-i5-i7 corei3 and PentiumG.
2100T models and models i3 i5 to 32 nm 2390T/2500T all new LGA1155 socket and the first two 2-cores and the latter as quadcore consumption does not exceed 35/45 watts (180nm Pentium III consumes 30W).
The architectural improvements come on the side: all with better integrated graphics-HD200 HD100 nearly 1GHz in the same package (and therefore nothing in the new IGP chipsets H67 and P67), the Z68 chipset unlock and overclock allowing all models beyond Turbo Boost 2.0, the oscillation frequencies ranging from 2.5 to 3.8 GHz and speaks to the 5.1 GHz OC no liquid nitrogen or a little cooler than conventional (octacore models are now confined to Xeon servers) AVX instructions to run OpenCL GPGPU, separate unit for transcoding HD video formats, improving performance by 20% compared to the previous layer i 1xxx core, it only remains for any sign of significant price low because even today half of sales for LGA 775 Intel core2 remains.
AMD delayed until next summer its Vision to 32 nm (that is distributed before its Fusion APU), the Bulldozer will support HT 3.1 ... ..
continue in 2011 if readers they prefer.
An unexpected and welcome support: PPC Linux Mint
Is forthcoming Linux Mint 10 Julia and while other distributions like Ubuntu or openSUSE come apart from the PowerPC architecture-as anachronistic and obsolete excepting understand all the architects of MorphOS - distribution commanded by Clement Lefebvre now splits into Debian based Ubuntu base and drive back to linux installation of more advanced and functional on those processors G3, G4, and so on.

The eclipse x86
and desktop and Intel Atom too, now that ARM came to the corporate servers and Facebook will happen to them , now survivor ecological green and low consumption will dominate netbooks, tablets (soon to leave the iPhone in a comfortable background) and phones with Android or WebOS on ARM. Now is when Nvidia announced Tegra 3 (or even saw Tegra 2) and beyond the difference that the ZuneHD from Microsoft brand in video acceleration compared to many iPods and MP4 China's mainland and islands, there are still a few products with this SoC (Marvell and Navy launched, Apple produces A4). In the enhanced features of Tegra 3 to launch by the end of 2010 in GPU acceleration or new microcode instructions without RISC still no information and only releases would clarify that year ... and we would implement Tegra 4 for 2012 in the cell responsible for leave in the shadows forever existing Desktop PC. The bad news is for: the very expensive Intel core i7, Windows 7 that can not adapt, excellent Phenom II x6 to return to the hands of scientists and modelers renders numbers and also for VIA Nano and micro 86_64. The GPU in a pill Advanced RISC Machine is everything from now on.
Of the Westmere family of III
Intel Gulftown X6 is appearing in the market for motherboards with LGA 1366 socket and there are core i7 as the 980X, it does so without any integrated GPU with HyperThreading trite that makes 12 threads where there are only 6 strands of code to spread the workload from 6 real cores and 6 virtual cores. Of superior performance compared to the Phenom II X6 and although both use similar solutions to overclock type Turbo Boost processing data and instructions in a recortadísimo time even outperform Xeon Nehalem. Rather than the Gulftown processors are home to dedicated servers for work, scores of virtual machines or huge databases while they spend a nucleus to signal processing for web streaming.
Of the Westmere family II
He now Lynnfield LGA 1156 Core i7 QuickPath Interconnect without paying much or more than a 45nm Bloomfield (Nehalem) and does so with a lower TDP thanks to its 32nm transistors Why not bet entirely by Intel QPI LGA 1366 and for all 2010 models? Perhaps the X58 chipset was too expensive for a core i3, perhaps too readily dismissed QPI DDR II or became obsolete for the next DDR IV. Yet prices are still too high, it has not been that Intel was on the verge of bankruptcy and had to be rescued by capital from the Arabian peninsula.
Of the Westmere family of I
Intel Clarkdale X2 (Core i3-i5) is called, the inventors of the microcontroller have done before AMD, have been combined into a single die DualCore CPU and GPU in an advanced state of "technicatura" to 32nm. Equate performance Phenom II X4. They do not handle triple channel memory (dual channel only) and fit into a socket LGA 1156. Models and chipsets: Core i5 650, 660 and 670 at frequencies of 3.2, 3.33 and 3.46 GHz, Core i3 all 5xx, Chipset Q57, H55, H57 and P55 without graphics processing and video HD within himself, not only commanding the northbridge and PCIe interface from the micro to the DVI and VGA mother, now those are cooler integrated or thermally efficient.
Mode-compatible CPU
End while support XP SP2 and Vista RTM from Microsoft (not that of XP SP3 and Vista SP1/SP2) begins processors that support virtualization do not have native instructions to run XP Mode in Windows 7 by VirtualPC software. In this there will be improvements of performance, he is a patch that will support XP that 7 does not already own the popular democracy of any microprocessor, and is a good attempt to update hundreds of millions of users and business premises - not Linux, not OSX, not BSD, OpenSolaris, not from XP on a partition XP NTFS to a capsule within the modern, agile and rendidor operating system that was promised four years ago.
Open-PC, designed by and for the Linux community
The project Open-PC has shown its prototype, which will be available from February.
Open-PC initiative has created a PC specially designed for Linux users. It has been molded with suggestions and community surveys to reach the final hardware and software.
In the absence of a few weeks to start sales, calling on the community that promote the extent possible.
