Poorly threaded web based tests like the SunSpider and Chalkboard benchmarks showed much larger gains than well threaded tests like our wPrime and Truecrypt benchmarks. Bulldozer – Family 15h. We focused on a simple floating point test because a customer needs to run parallel floating point calculations. Our final test, Chalkboard, shows a seven percent advantage in favor of Piledriver.

Username or Email Address Password. Look at this cost comparison for machines for similar price: I think you should try asking your users what tasks they care about.

Bulldozer, like the original Phenom, was a power hog. You may unsubscribe from the newsletter at any time. Even old benchmarks like Whetstone or the Livermore Loops are often treated with suspicion. Komodo was to launch in on the FM2 socketbut this never happened. That explains their current financial situation….


It is clearly too simplistic for that, but good enough to push CPU usage to the limit. I know we are running bc. Thus, marketing chooses whatever term suits their interests. But you say it does all the internal calculations, including operations with fractions, with integers? This page was last edited on 21 Decemberat I believe you may have inadvertently included turbo-scaling losses in with your calculations for CMT scaling losses.

I realized that comparing prices per GHZ makes no sense since we have seen that the number of operations per GHZ depends heavily on the processor.

All of the above really just bulldzer down to re-running my earlier Hyper-Threading Performance tests again on AMD systems. We are already familiar with the two extreme points of this design space: This site may earn affiliate commissions from the links on this page.

AMD Bulldozer/Piledriver Modules and Hyper-Threading

If I gave the system two independent threads rather than one, how much pilwdriver will it give me in return for my effort? The pow function looks a little longer than it needs to be maybe error and corner case handling?

Retrieved 21 September The big take away from our testing here is that the Piledriver core is without question faster than the Bulldozer core. Performance relative to 3.


Does Piledriver deliver where Bulldozer fell short? All articles with unsourced statements Articles with unsourced statements from August Retrieved 23 March Retrieved from ” https: All these similarities make it easy to compare TDPs and clock speeds between the new parts and the old:. But all of this may be a moot point.

Our final test, Chalkboard, shows a seven percent advantage in favor of Piledriver. No, turbo is disabled, and clock speed is set to a fixed 3. Our Bulldozer chip offers significantly less stable performance than our Piledriver chip, with frame rate drops every seven seconds or so, compared to drops every twenty second on the Piledriver system. Retrieved 22 March The changes over Bulldozer are incremental. It targets desktop, mobile and server markets.
