That, I don't know. My guess is they are about the same as the i7, but provide ECC. You know the die is pretty much the same on all parts within a family. They blow a few fuses to turn off capabilities and "bin" the parts based on thermal performance/clock speed. BTW, I have an unopened i5-3470S sitting here waiting for testing. I use the i5 S series (low power 65W) for my Limulus boxes. There is a 65W i7, but it is a little pricey. In my experience the Sandy Bridge and now Ivy Bridge provide incredible performance and would be a hard target for AMD in any case. -- Doug > > rgb > >> >> -- >> Doug >> >>> >>> Comments from anyone else? >>> >>> rgb >>> >>>> >>>>> I would have hoped that AMD would dig in an innovate and >>>>> regain at least parity if not the lead, because it is good for the >>>>> industry for Intel to have serious competition, but while Intel could >>>>> make money and survive as second best to AMD, AMD can't make any >>>>> money >>>>> as second best to Intel... >>>> >>>> We must split of course the 2 worlds of HPC performance. >>>> In fact htere is 3 but let's do a rough 2 world division >>>> >>>> a) floating point or vectorized performance (can be integers as well) >>>> >>>> We skip A : the manycores have won there. >>>> >>>> b) integer performance non-vectorized >>>> >>>> For integers and branches if i take a huge program like Diep. >>>> >>>> http://www.lostcircuits.com/mambo//index.php? >>>> option=com_content&task=view&id=105&Itemid=42&limit=1&limitstart=13 >>>> >>>> More is better. >>>> >>>> i7-3960X-EE : 2.0 Million chess positions a second (12 logical >>>> cores) >>>> i7-980x turbo: 1.85 Million chess positions a second (12 logical >>>> cores) >>>> i7-3770k: 1.47 million chess positions a second (8 logical >>>> cores) >>>> AMD Phenom X6 1100T : 1.34 million chess positions a second (6 cores) >>>> AMD Phenom X6 1090T : 1.30 million chess positions a second (6 cores) >>>> FX-8150 : 1.22 million chesspositions a second (8 mini cores) >>>> >>>> The FX-8150 is AMD's latest 'bulldozer' CPU. >>>> >>>> The problem is the new generation FX-8150 at a NEW process >>>> technology, with 2 billion transistors or so (caches counted >>>> - the initial press release from AMD - not the later one where they >>>> creatively not counting things reached 1.2 billion) is not beating >>>> their own old design. >>>> >>>> Furthermore another big problem is power usage. >>>> >>>> http://www.lostcircuits.com/mambo//index.php? >>>> option=com_content&task=view&id=105&Itemid=42&limit=1&limitstart=6 >>>> >>>> Under full load: >>>> >>>> Phenom X6 1090T : 69.6 watt, >>>> Phenom X6 1100T : 92 watt >>>> >>>> We see how the 1100T already was clocked a tad too high by AMD, which >>>> explains the huge power increase. >>>> >>>> Now the FX-8150 : 115.2 watt >>>> >>>> As if Law of Moore garantueeing progress doesn't exist... >>>> >>>> As for you, in many benchmarks you did do maybe multiplication was >>>> important.
