Bulldozer Server Benchmarks Not Promising 235
New submitter RobinEggs writes "Some reviews of Bulldozer's server performance have arrived. Ars Technica has the breakdown, and 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. ... 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."

TPC-C is performed on Windows 2008 see http://www.tpc.org/tpcc/results/tpcc_result_detail.asp?id=111111501
Anantech tested on Windows 7.
It is known that Windows 7 and 2008 are not optimized for Bulldozer, especially at the task scheduling level.
So we do not know the real power of the Bulldozer architecture in the Windows world yet
See http://hexus.net/tech/news/cpu/32394-bulldozer-benchmarks-correct-definitive which unfortunately only has very few benchmarks.
You can also look at the phoronix site, where Bulldozer is tested on Linux.

Sadly AMD simply has not performed over the last year or two, with no real answers to Intel's I series.
While i totally agree on your first statement, i don't on the second. Last two years you say?.. My desktop is 1 year old, running a quad-core phenom@3.4GHz. Not only was it the best-value-for-money, costing me only 169 euro for the processor, it is also one of the fastest around - up to this very day, even for single-thread tasks.
Here's a hint. Artificial benchmarks don't say a thing. There's one thing where AMD is very, very good and outperforms intel in any way, and that's memory management. I couldn't care less for floating point performance, or any other dry/wetstone-like test. What does count though, is how well a processor does in doing several tasks at a time. Running 2 games, at the same time (or 6 if i wish). And the OS-i-be-ashamed-to-say-the-name-off. And a numbercruncher. And a webbrowser with a dozen tabs. While chatting on skype. And drawing a 30-layered image with the gimp.
And this box - doesnt' give a kick. It just does it - and each task runs just as well as were it running alone. Now tell me again, how was AMD not good on the desktop last 2 years?
A much better source for this kind of information. (Score:5, Informative)
