In 7-zip we have an eight percent gain, and in the SunSpider benchmark we have the largest advantage shown in our testing, a whopping 12 percent. Yep, performance scaling with SMT is dependent on the workload. Views Read Edit View history. But all of this may be a moot point. Retrieved 7 January

AMD’s Bulldozer core compared with Piledriver
That explains their current financial situation…. This site may earn affiliate commissions from the links on this page.
From Wikipedia, the free encyclopedia. I know we are running bc. But you say it does all the internal calculations, including operations with fractions, with integers? Does Piledriver deliver where Bulldozer fell short?
Looking at our Counter-Strike: And what do we need FPUs for then?
Steamroller – Family 15h 3rd-gen. All of the above really just boils down to plledriver my earlier Hyper-Threading Performance tests again on AMD systems.
AMD’s Bulldozer core compared with Piledriver – SemiAccurate
Retrieved 16 January Windows 7 SP1 bit was installed, along with all additional MS updates and the two scheduler patches Microsoft released for Bulldozer last year. Nexiuz is a game that, even with Vsync disabled has a frame cap at 63 frames per second.
But all of this may be a moot point. Sorry, your blog cannot share posts by email. Email will not be published required.
Power consumption is higher for AMD affects both electricity costs and densityespecially at higher clock frequencies. However, when considering two threads, there is a continuum of design points that range from bul,dozer threads on an unmodified CPU core 1. Ideal speedup is 4. A Performance Metric The essential characteristic of having two threads is that the software developer must parallelize a task into two mostly-independent threads this is a hard problem!
The big take away from our testing here is that the Piledriver core is without question faster than the Bulldozer core. Retrieved from ” https: For example, on my Ivy Bridge 4. The following two graphs compare the throughput of 8 vs.

bulldoozer The summary is here: If Turbo really was enabled, you would see a bend in the curve between 1 and 4 threads, rather than linear scaling. The pow function looks a little longer than it needs to be maybe error and corner case handling?
Intel Lynnfield Core i, MHz. Thus, marketing chooses whatever term suits their interests.
