All intel xeon processor list pdf are listed here in chronological order. Introduced in the third quarter of 1974, these components used bipolar Schottky transistors. The memory is divided into odd and even banks.
First used in the Compaq Deskpro IBM PC-compatible computers. 2 Model 25 and Model 30. Used segment registers to access more than 64 KB of data at once, which many programmers complained made their work excessively difficult. Included memory protection hardware to support multitasking operating systems with per-process address space. Reworked and expanded memory protection support including paged virtual memory and virtual-86 mode, features required at the time by Xenix and Unix.
First used by Compaq in the Deskpro 386. The Intel i376 is an embedded version of the i386SX. 185 million transistors at 1 μm and 900,000 at 0. Identical in design to 486DX but without a math coprocessor.
The first version was an 80486DX with disabled math coprocessor in the chip and different pin configuration. Pin count 168 PGA Package, 208 sq. 39 SPECfp95 on Gateway P5 256K L2 and 3. 66 MHz bus clock rate, 512 KB 0.
