In late 2006 Intel began instead using the name Intel 64 for its implementation, paralleling AMD's use of the name AMD64. [35] The first processor to implement Intel 64 was the multi-socket processor Xeon code-named Nocona in June 2004. In contrast, the initial Prescott chips (February 2004) did not enable this feature.
Jan 7, 2024 · When the Itanium was introduced in 2001 as Intel’s first 64-bit CPU, its 32-bit performance constraints drew criticism. With 320 million transistors and clock frequencies of 733 MHz and 800 MHz, the 180 nm Merced core debuted.

Nov 19, 2023 · The 8086 was a 16-bit processor, building upon earlier 8-bit Intel processors. But it was the next generation 80386 in 1985 that truly revolutionized PCs. The 80386, also called i386, introduced the first 32-bit instruction set for x86.
Sep 8, 2018 · Intel Begins with The 4004. The first microprocessor sold by Intel was the four-bit 4004 in 1971. It was designed to work in conjunction with three other microchips, the 4001 ROM, 4002 RAM,...
In the mid-1980s, Intel i860 [3] development began culminating in a 1989 release; the i860 had 32-bit integer registers and 32-bit addressing, so it was not a fully 64-bit processor, although its graphics unit supported 64-bit integer arithmetic. [4]
This generational list of Intel processors attempts to present all of Intel's processors from the 4-bit 4004 (1971) to the present high-end offerings. Concise technical data is given for each product.
Jul 8, 2023 · Personal computers began using 64-bit processors in the early 2000s, but these processors were already available for servers and workstations in the 1990s. 64-bit processors can process large amounts of data and can access much more memory.
