Nice - HQ encode, 8-core bulldozer
Got around to a decent video encode, something I'd have prior, with
certain likelihood, run into issues, at the least with further audio processing I also run. Quadcores then, octals now. Distribution across eight cores can also be seen favorably, a token estimate at 20% processing demands, on average -- less linearity to any code specifics (modeling for a multi-core environ), than reliance on AMD's generic distribution for cores. Not that 20% figure need be so radically different for resolution across quadcore, either. Temps aren't especially significant, or also decent. What it does is become the biggest jump since an I'd abandoned an Intel Duron single-core -- through and subsequent dualcores, including maxing those to same-socket quadcores (w/ both AMD and Intel, same-class MBs). For me that makes this my next-generation update, a month or two ago, when deciding to update to an octal. As I can't think of any other (program) usage I'll likely engage, offhand, more demanding, or so tailored for a wider range of cores. If it weren't for AMD, for all of what an Intel octal designates -- not much, actually, in any practical sense -- and for all of what is pretty much left, Intel hyper-threading -- there's not much else, being AMD hasn't a lot else to show for itself. A recent cheapening Bulldozers for otherwise a nondescript achievement, at or below quads, notably for those models [above] in application to make a further distinction to marketing its Ryzen platform. The Trickle-Down Effect, as it's at times also called. |

Yeah, I recently started using Windows Movie Maker a lot more than usual. At the beginning of a project, WMM happens to reencode the entire video into its own internal Mpeg-4 implementation (WMV), before it even begins allowing you to edit it. You see a huge reencoding process go on for half-hour depending on how big the video is. You see every core get pegged at 100% during this time, which is a wondrous sight if you have 8 cores. In fact, it has to redo this encoding everytime you restart the project, so it's best to simply leave the project running in the background, and to never shutdown your computer, just let it go into standby if you need to save electricity.

Yousuf Khan I haven't largely needed to peg mine for any considerable length of time. Other than audio-only manipulations, there's not much else I can think of readily, that I have, to use each core to its fullest. There's also a reverse-case proviso, in the BIOS, curiously to disable cores in "paired" sets, reductively all the way down to a single core processor. Two pairs, presumably, although I haven't yet engaged or tried it. Although audio decodes still have practical limits, which I set out to find, independently and far before any such condition. A software decoded playback condition that varies according to how audio is being processed, for as many effects selected and added into the playback (transient recovery, vacuum tube harmonics, etc.) Of course, that I now have more such effects available is the plus side. An improved sense for effect selections of which ones, overall among many more capable of overloaded condition, at a minimum will add the most integrity to improved sound fidelity, far before an "overload" CPU condition or only in part a raw determinate of CPU limitations. I'm not sure Intel hyper-threading might react differently to that, a contingency of efficiency for code, however unique its distribution means to cores. In reading reviews of the AMD octal, I ran across one which said, fully loaded and with the power-boost enabled, (as it is by default in the BIOS for a 3.2Ghz to 4Ghz condition when met), that the FX-8300 then will draw 285 watts. That's a lot of power and then some...they also overclock well at farther extremities. |

A company I worked for actually built a cluster of Bulldozer Opterons.
Perhaps the only one in the country that did? They reckoned they went pretty well in Centos 6. The head IT guy said he was using said CPU at home for video encoding. |

The Bulldozers were extremely heat-tolerant, that's why they could be overclocked so heavily, still no current Intel Core or AMD Ryzen processor has matched the FX-9590 for stock core speeds yet, 4.7 & 5.0 GHz. But of course, you didn't actually get much extra performance even at those high MHz, as the cores just spun their wheels wildly rather than do actual work. -- Sent from Giganews on Thunderbird on my Toshiba laptop |

And, still, not a bad price for all the esoterics of 220W at the upper end of Bulldozers. Under $150/US. The review I'd mentioned ( lowest-wattage octal Bulldozers) is a bit sketchy now to fully recall: He'd probably set it up for overclocked, and, second, used a suitable program, a spread workload across all cores, in order to achieve the 285W extremity claimed reached. A lot of processing power, no doubt, now at the higher end available. And reasonable, too. Advanced and efficiently designed for smooth sailing. As well more of specialized crowd, I'll bet, a "limited" concern with cloud services and portable devices filling an interim gap for actually building or learning computers, when simply operating occasional programs and games is an affair of convenience alongside social media or communications from hybrid smartphones and a likes. |
