The Dell OptiPlex XE is a special version designed for equipment manufacturer, retail/point-of-sale (POS) systems. [37] They are based on the standard OptiPlex models with added features; such as a higher heat threshold, MIL-STD 810G testing [38] and powered USB/Serial.
To keep costs low on high-volume competitive products, the CPU core is usually bundled into a system-on-chip (SOC) integrated circuit. SOCs contain the processor core, cache and the processor's local data on-chip, along with clocking, timers, memory (SDRAM), peripheral (network, serial I/O), and bus (PCI, PCI-X, ROM/Flash bus, I2C) controllers.
Each model of Dell's OptiPlex line of computers typically includes an Ultra-Small Form Factor (USFF) chassis option. In the Core 2 era, these machines used 8.9 cm (3.5") desktop hard drives and external power supplies, such as the OptiPlex 745 and 755. More recent units use 6.4 cm (2.5") laptop hard drives and have integrated power supplies ...
The CPU itself can withstand 200,000 to 1,000,000 Rads and temperature ranges between −55 and 125 °C. The RAD750 packaging and logic functions has a price tag in excess of US$ 200,000 [ citation needed ] : the high price is mainly due to radiation hardening revisions to the PowerPC 750 architecture and manufacturing, stringent quality ...
