Bulldozer's Just As Bad With Servers

RobinEggs (1453925) writes "Some reviews of Bulldozer's performance in servers have arrived, and Arstechnica has a breakdown. The results are pretty ugly. Apparently Bulldozer fares just as poorly with servers as with desktops.

From the article: 'One reason for the underwhelming performance on the desktop is that the Bulldozer architecture emphasizes multithreaded performance over single-threaded performance. For desktop applications, where single-threaded performance is still king, this is a problem. Server workloads, in contrast, typically have to handle multiple users, network connections, and virtual machines concurrently. This makes them a much better fit for processors that support lots of concurrent threads. Some commentators have even suggested that Bulldozer was, first and foremost, a server processor; relatively weak desktop performance was to be expected, but it would all come good in the server room.

Unfortunately for AMD, it looks as though the decisions that hurt Bulldozer on the desktop continue to hurt it in the server room. Although the server benchmarks don't show the same regressions as were found on the desktop, they do little to justify the design of the new architecture.'

It's probably much too early to start editorializing about the end of AMD, or even to say with certainty that Bulldozer has failed, but my untrained eye can't yet see any possible silver lining in these new processors."
