AMD Shanghai Opteron CPUs On Linux
Last quarter AMD introduced their "Shanghai" Opteron processors that join the ranks of Intel's Harpertown Xeon CPUs that are 45nm quad-core server/workstation parts. Initial reviews of these new AMD Opteron processors have been very positive, but how do these chips perform with Linux? In this article we have our hands on a few of the fastest Shanghais, the AMD Opteron 2384 clocked at 2.7GHz, as we see how well they compare to the older "Barcelona" Opteron processors.
The AMD Opteron 2384 operates at 2.7GHz, is a true 45nm quad-core processor, runs on a 1000MHz HyperTransport bus, provides 512KB of L2 cache, and offers 6MB of shared L3 cache. The Shanghai succeeds the Barcelona family, with many technologies being shared or built upon between the two generations, but the Barcelona only offered 2MB of shared L3 cache, speeds up to only 2.5GHz, and was built on a 65nm SOI process. Additionally, the memory controller found with the Shanghai CPUs now supports Registered DDR2 memory speeds up to 800MHz compared to 667MHz with the Barcelona. The Shanghai family is also ready for HyperTransport 3.0, but the first batch of Shanghai Opterons do not support this version.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
