Analysis: What's new for the PC of 2005?
Only incremental updates are expected over the next year
IDG News Service - Consumers thinking about buying a new PC in 2005 might be better off putting off their purchase until 2006. With few major changes in PC hardware or software due over the next year, the PC of 2005 is likely to look awfully similar to the PC of today.
Big changes aren't due until 2006, when the Longhorn operating system from Microsoft Corp., 64-bit applications and optical drives based on the Blu-ray Disc and HD-DVD formats will become available to the average user.
Still, that doesn't mean there are no technologies worth looking into for those who plan to upgrade in 2005.
Intel Corp. and Advanced Micro Devices Inc. are expected to unveil dual-core chips -- which contain two processor cores on a single piece of silicon -- by the end of 2005, although they probably won't appear in mainstream PCs until well into 2006, said Stephen Baker, director of industry analysis at NPD Techworld in Reston, Va.
Intel will likely boost the cache memory in its Pentium 4 processor, and AMD is expected to increase the clock speed of its Athlon 64. But these changes will be incremental. A more substantial shift in processor performance, the move to 64-bit computing, probably also won't happen next year, although Microsoft is expected to finally release a 64-bit version of Windows XP in early 2005.
Bigger changes can be expected in chip sets, which handle the flow of communication between the processor and the rest of a PC. A new series of Intel chip sets supporting the PCI Express interface and DDR2 (Double Data Rate 2) memory will trickle down to mainstream systems, or those priced at about $800, in 2005, Baker said.
PCI Express will allow data to travel faster between the chip set and peripheral hardware such as graphics cards and storage. Intel has billed its introduction as one of its most important upgrades in a decade. While that might be stretching it, mainstream users will begin to see more and more products that take advantage of the increased bandwidth in 2005, Baker said.
DDR2 will allow memory chips to move data at faster clock rates. The older DDR standard is reaching the limit of its effectiveness as memory clock rates exceed 400 MHz. Memory chip vendors are expected to produce larger amounts of DDR2 in 2005, bringing costs down and allowing vendors to put faster memory chips in cheaper PCs.
PCI Express and DDR memory will also appear in notebooks from early 2005 with the introduction of Intel's next-generation Alviso chip set. Notebook sales have been growing faster
