Blu-Ray, SSD, 64-bit … Already ready, these technologies will be deployed on all computers soon. Should we wait to be equipped?
USB 3
On the occasion of CES 2010, many manufacturers have announced products that are compatible with USB 3 Seagate and Western Digital. USB 3 promises to deliver data rates 4-5 times faster than USB 2.
USB is limited in its version 2 transfer rates of 480 Mbit / s theoretical. But the volume now kept on computer (several tens to hundreds of GB) are constantly increasing.
It was not until 2011 however that USB 3 is required. Indeed, Intel does not integrate it into its chipsets motherboard before that date. Note that USB 2 is not compatible with the USB 3 (but the USB 3 will be backward-compatible) will therefore change the motherboard or expansion cards of hope.
Is almost a certainty now. The ray Blu-ray store has expanded and now equal to the ray DVD movies. Even for software, Blu-ray makes sense because of the limitations of the DVD storage (9GB for double layer, cons 25-50 GB for Blu-ray).
However, some programs now operating on two or three DVDs. Similarly, storage media, the DVD is not enough to put his personal files. For all these reasons, and because the price of Blu-ray has fallen below 100 euros, this format will democratize on computers.
Is the price of drives is still high, between 150 and 300 euros.
LCD TVs and monitors are now set on the image format 1080p (1920 x 1080 pixels). This format extends the world of computers, and off the screen change that requires (often 23 or 24 inches at least), it requires the latest equipment.
As the video stream is more complex to treat, there should be a modern graphics card (at 80-120 euros). On the other hand, the HDMI connection allows the use of an LCD monitor as a TV. But to do so, you need a graphics card with this type of interface.
Although still a minority in the currently 64-bit architectures becoming common. What do we talk? Our current computer architectures are based on memory address encoded in 32 bits. But this technology limits the management of the RAM to 4 GB in quantity.
However, current applications increasingly approaching that limit. 64-bit systems are ready (Windows 7), but the step means leaving aside the old devices are only compatible with 32-bit systems.
The software drivers and hardware are different between 32 and 64 bit architectures. That is why manufacturers delay the moment of migration. But it is almost inevitable, and will intervene massively either Windows 7 or later on under his successor (in 2013).
In the short term, the SSD will not become and replace hard drives. However, the manufacturers are now considering as a complementary solution.
The price of the 32GB hard drive is between 100 and 150 euros now, thereby placing them on high-end configurations first. The DSS offers an access time much lower than conventional hard drives with flash memory.
On the other hand, they are considered more reliable. They could therefore be used to store data in the operating system to improve responsiveness in the first place. For if the 256GB SSD already exist, their price is too high (over 600 euros) for their widespread use.
DDR3 is just beginning to spread on midrange computers. His prices were lowered, but also its capabilities have improved.
There are now memories clocked at 2 GHz to 2.4 GHz, 800 MHz cons for DDR2. The timings, ie the availability of memory arrays are also much better. There are, for example at 2 GHz with 8-8-8-24 Corsair.
However, for 6 GB of DDR3 2 Ghz, it will cost you between 350 and 400 euros today. But to 4GB of DDR3 to 1.2 GHz, count around 120 euros. This is still twice as expensive as DDR2, but costs continue to decline.
More conventional but nonetheless inevitable, stop support for older operating systems will force users buying new hardware, or downloading new software, change their computer.
Indeed, from Windows XP to Windows 7, the hardware recommendations climb: the dedicated graphics card with 128 MB is required, 2 GB RAM is preferable, and a 1.6 GHz dual core processor at least is recommended.
Linux and Mac OS X are also involved, but to a lesser extent. Their GUIs are generally lighter and reagents.
This should be fairly insensitive at first, but it will probably win the field with future models.
Manufacturers of processors, namely Intel and AMD are currently working to combine processor and graphics card to improve the effectiveness of 3D calculations.
Today, graphics chipsets are integrated into the motherboard. By moving the 3D calculations on the processor, it could save time and efficiency. However, the rendering multiply with new interfaces (including Aero in Windows 7).
This development will not, at least initially, to spend dedicated graphics cards, much more efficient. But it will speed up some simple treatments.
