Which CPU brand is noted for 32-bit servers?

Opteron is a brand of server processors developed by AMD, specifically designed for use in 32-bit and later 64-bit server environments. The Opteron processors were significant in the server market for their capability to handle dual and multi-core processing, which allowed for improved performance in server workloads. Initially, these processors were well-known for their efficient performance and ability to run 32-bit operating systems effectively, making them an attractive option for server deployments during the time when 32-bit systems were prevalent.

Other options, while they may have also been used in server environments, do not specifically have the same historical association with 32-bit architectures in the same way Opteron does. For instance, Xeon processors are primarily designed for enterprise-level servers, but they have evolved to focus more on 64-bit computing. Core i7 and Ryzen processors are predominantly aimed at consumer and high-performance computing rather than being specifically noted for 32-bit servers.
