Via's DDR333 chipset improves memory bandwidth

Via Technologies Inc., the Taipei-based chip maker, announced Thursday its Apollo P4X333 chipset for Intel Corp.'s Pentium 4 processor, which Via said improves memory bandwidth by 25 percent over its previous P4X266A product.

The DDR SDRAM (double data rate synchronous dynamic RAM) chipset features a 533MHz processor bus and AGP 8X bandwidth, which delivers 2.1G bytes per second to the graphics engine, Via said. It supports the USB (Universal Serial Bus) 2.0 standard and Ultra ATA-133 interface.

"This is a very balanced chipset architecture," Chewei Lin, the company's vice president of product marketing, told journalists here. "It offers faster memory performance and better 3D graphics and gaming performance."

The P4X333 is Via's entry in the DDR333 market, which several chip makers are expecting to take the bulk of the memory market by next year. The P4X333 is shipping now, said Lin, though he did not provide pricing information. He added that design of a DDR400 chipset is well under way, and that the company expects to put it into production by the end of next year.

Via still faces controversy over its P4X266 products, which Intel Corp. says violates its microprocessor-related patents. The dispute is the subject of lawsuits still in progress in several countries.

It’s perfect for mobile workers. Just take it out — it’s small enough to sit anywhere — turn it on, load a sheet of paper, and start printing.
