The Dimension 4500S uses the 845G chipset, which contains integrated graphics processing, alleviating the need for a separate graphics card, said Linda Gerardi, Dimension product marketing manager for Dell.
The 845G also supports both 400MHz and 533MHz front-side bus speeds, while the Dimension 4500's 845E chipset only enables the 400MHz front side bus speed, and lacks the integrated graphics, she said.
Both chipsets enable fast downloads from peripheral devices, such as digital cameras or MP3 music players, through support for USB 2.0 ports.
A typical configuration of the Dimension 4500, including a 2.26GHz Intel Pentium 4 processor with a 533MHz front side system bus, 256Mbytes of Dual Data Rate Synchronous Dynamic RAM (DDR SDRAM), a 20Gbyte hard drive, a 17in monitor, and a 32Mbyte RAGE Ultra Graphics Card from ATI Technologies, is priced at $1,099 (£752).
The Dimension 4500S, with a typical configuration of a 1.7GHz Intel Celeron processor, 256Mbytes of shared DDR SDRAM, a 20Gbyte hard drive, a 15in monitor and a 48x CD-ROM drive, is at priced at $799 (£547).
