This plot shows how throughput scales as more instances of a workload are run concurrently on an AMD FX, normalized to four threads.

The big take away from our testing here is that the Piledriver core is without question faster than the Bulldozer core. NET benchmark, Piledriver is once again ahead by eight percent. The K suffix denotes an unlocked A-series processor. The Core i is a quad-core CPU at 3.

If Turbo really was enabled, you would see a bend in the curve between 1 and 4 threads, rather than linear scaling. But you say it does all the internal calculations, including operations with fractions, with integers?

And what do we need FPUs for then? However, when considering two threads, there is a continuum of design points that range from time-slicing threads on an unmodified CPU core 1. All these similarities make it easy to compare TDPs and clock speeds between the new parts and the old:.


AMD’s Bulldozer core compared with Piledriver

As configured see above tablethe AMD chips already consume more power. Look at this cost comparison for machines for similar price:.

Look at this cost comparison for machines for similar price: Starting with Cinebench we can see that Piledriver offers an eight percent advantage bulldozeg the single threaded test and a smaller six percent advantage in the multi-threaded test.

I think your timing script also has some timing precision issues. Thomas Ryan Author at SemiAccurate.

AMD’s FX-8350 analyzed: Does Piledriver deliver where Bulldozer fell short?

AMD was rumored to be working on a new revision of Bulldozer that would reduce power consumption, but the core if it existed never saw the light of day. The difference in scalability is not large.

This newsletter may contain advertising, deals, or affiliate links. Bu,ldozer, the most important thing to retain from this discussion is that we really must focus on calculating TPE throughput per EUR values and stop caring about announced GHZ and announced number of cores.


Retrieved 11 March Behold Bulldozer’s second coming”. The summary is here: Retrieved 21 September Now this 10 to 15 percent figure is a combination of two kinds of enhancements.

Piledriver (microarchitecture) – Wikipedia

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. Piledriver uses the same “module” design.

We focused on a simple floating point test because a customer needs to run parallel floating point calculations.

Bulldozer – Family 15h. Retrieved 7 January Power consumption is higher for AMD affects both electricity costs and densityespecially at higher clock frequencies. Intel Lynnfield Core i, MHz. Views Read Edit View history.
