تاپیک جامع معرفی ، اخبار و بحث پیرامون AMD Bulldozer

[.D3VIL.]

سلام دوستان.
امروز پردازنده های Bulldozer عرضه شد و حدودا چندتا سایت مختلف Review هایی از این پردازنده منتشر کردند:

تعدادشون زیاده....

متاسافنه شاهد ضعف Performance شدیدی در پردازنده های Bulldozer (حتی ضعیف تر از سری قبل یعنی PhenomII هستیم)
به گفته عده ای اینت فت شدید Performance مربوط به مشکلی هست که در پردازنده های Bulldozer FX وجود داره که Application های موجود توانایی استفاده از 100% Performance این پردازنده یا استفاده از قابلیت های Multi Core این پردازنده رو ندارند.

این پردازنده با توجه به معماری جدید و دارا بودن 8 هسته در بیشتر تست های Multi Thread از پردازنده Intel 2500K که حدودا 25$ مدل FX-8150 از اون گرونتره ، بهتر عمل میکنه.
در کل یک افتضاح بزرگ بعد از این همه تبلیغ رو به بار اورد.....!

AMD FX-8150 is missing its performance expectations by a fair margin. Not to mention performance gains in its own presentation, these expectations were built up by how AMD was shaping the product to be a full-fledged enthusiast product with significant performance gains over the previous generation
AMD ill-marketed the FX-8150. Hype is a double-edged sword, and should not be used if you're not confident your offering will live up to at least most of the hype. AMD marketed at least the top-tier FX-8000 series eight-core processors as the second coming of Athlon64 FX.
FX-8150 launch isn't backed up by launch of other AMD FX processors. This could go on to become a blunder. The presence of other FX series processors such as the FX-8120, six-core and four-core FX processors could have at least made the price performance charts look better, given that all FX processors are unlocked, buyers could see the value in buying them to overclock. TweakTown took a closer look into this.
There are no significant clock-for-clock improvements over even AMD's own previous generation. The FX-8150 drags its feet behind the Phenom II X6 1100T in single-threaded math benchmarks such as Super/HyperPi, the picture isn't any better with Cinebench single-threaded, either.
Multi-threaded data streaming applications such as data compression (WINRAR, 7-ZIP) reveal the FX-8150 to catch up with competition from even the Core i7-2600K. This trend keeps up with popular video encoding benchmarks such as Handbrake and x264 HD.
Load power draw is bad, by today's standards. It's not like AMD is lagging behind in silicon fabrication technologies, or the engineering potential that turned around AMD Radeon power consumption figures over generations.
Price could be a major saving grace. In the end, AMD FX 8150 has an acceptable price-performance figure. At just $25 over the Core i5-2500K, the FX-8150 offers a good performance lead.
Impressive overclocking potential. We weren't exactly in awe when AMD announced its Guinness Record-breaking overclocking feat, but reviewers across the board have noticed fairly good overclocking potential and performance scaling.
