Intel has released processor with a variety of bus / memory widths. The 386SX had a 16-bit data width, the 386DX and 486 had a 32-bit bus width, and the Pentium had a 64-bit data bus.
44 bits
You can get any graphics card you want, your CPU doesn't matter. What matters is if you have a PCI, PCI-E, or AGP bus to plug the card into.
Its called the backside bus or cache bus. There's also the ATC bus. Back Side Bus Front side bus or cache bus Back Side Bus
The original Intel Pentium was the first to have a 64-bit data bus while it's predecessor, the i486 was the first to feature an on-die L1 cache.

The width of the address bus on the 8085 was decided based on a compromise between functionality, cost, and complexity. Intel decide to use 16 bits, as that was in keeping with common design at that time, and also because the 8085 was actually an enhanced version of the 8080.
A Intel system bus is a single computer bus that connects the components of a major computer system. The system bus also referred to as crossbar switch.
For the Pentium the front side data bus is 64 bits wide. The back side is 32 bits wide.
Front Side Bus (for older Intel CPUs). Hypertransport (for AMD) and CSI (for newer Intel CPUs)
They are two different companies. Cyrix is a smaller company, their processors are not as performant as Intel ones, however they would exponse exactly the same set of instructions. Regardless the lack of performance compared with Intel, Cyrix had a very good market in the mid 90s, for people that did not have the money to purchase Intel. Instead of purchasing an Intel at 166 Mhz with 400 dollars, one could purchase a Cyrix at 150 Mhz for only 99 dollars. Of course, the performance of the cyrix would be far smaller, but the price difference would make it worthwile. Had a Cyrix between 97 and 2000. Was very happy with it.
