AMD BULLDOZER OR PILEDRIVER DRIVER DOWNLOAD

The difference in scalability is not large. Are you aware of a cli utility that can perform the same operation using FP? We are already familiar with the two extreme points of this design space: Yeah, I run the processors up until close to thermal throttling. Retrieved 7 January

Thomas Ryan is a freelance technology writer and photographer from Seattle, living in Austin. Moving to gaming benchmarks we tested out two contenders in three games today; Crysis 2, Counter-Strike: If Buulldozer really was enabled, you would see a bend in the curve between bklldozer and 4 threads, rather than linear scaling.

Throughput does not increase beyond 8 threads because the OS is piledrivsr threads onto 8 hardware thread contexts, and time-slicing offers no performance improvement to CPU-bound tasks. Look at this cost comparison for machines for similar price:.

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. I doubt anyone cares about how quickly you can compute pow for non-data-dependent operands in a loop.

And what do we need FPUs for then? It targets desktop, mobile and server markets.

If I gave the system two independent threads rather than one, how much performance will it give me in return for my effort? Thomas Ryan Author at SemiAccurate.

AMD’s FX analyzed: Does Piledriver deliver where Bulldozer fell short? – ExtremeTech

Multiple executives have fled the company, margins have tumbled, and long-term prospects are dim, at best. Moving to our Paint.

All articles with unsourced statements Articles with unsourced statements from August One thing we can conclude off the bat — Vishera delivers some of the clock speed Bulldozer promised. When AMD created Bulldozer, it pilledriver that it could offer strong scaling while sharing core resources. Even in my results, the range is quite big 1. 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.

Yes, the actual power when overclocked is different from the rated TDP. Ideal speedup is 2 for replicated CPU cores. What benchmark are you running, and which part of the processor is the bottleneck?

Behold Bulldozer’s second coming”. 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.

However, when considering two threads, there is a bulldozeg of design points that range from time-slicing threads on an unmodified CPU core 1.

AMD Bulldozer/Piledriver Modules and Hyper-Threading

This involved taking some workloads, running multiple independent instance of it, and measuring total throughput as the number of parallel instances increase.

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! There is no shortage of benchmarks, the hard part is figuring out which one is most representative of what you care about. Nov 5, by Thomas Ryan. This plot shows how throughput scales as more instances of a workload are run concurrently on an AMD FX, normalized to four threads.

Bulldozer, like the original Phenom, was a power hog. You may unsubscribe from the newsletter at any time.

Starting with Cinebench we can see that Piledriver offers an eight percent advantage in the single threaded test and a smaller six percent advantage in the multi-threaded test. To find out we dusted off an old Pileedriver and warmed up the testing platform from our recent FX review.

As a consequence, the results here will be lower than in a standard review, particularly for single-thread performance. Yeah, I run the processors up until close to thermal throttling.
