[QUOTE="kszabo, post: 423207, member: 61646"] IMHO [B]TPD has very-very limited informative value about the real power consumption of a CPU[/B]. Important is the architecture and producing method (45nm vs 65 nm). TPD is important for PowerSupply and Motherboard power design, has not much to do with the average power consumtion of the CPU. The CPU tests prove that newer (65nm) AMD Athlons have quite good [B]"idle" consumption [/B](ca. 10W), Phenom Is are worse (ca. 20 W), Phenom IIs (45nm) are very good again (<10W). look at this here for idle power consumption: [URL="http://www.lostcircuits.com/mambo//index.php?option=com_content&task=view&id=54&Itemid=42&limit=1&limitstart=4"]http://www.lostcircuits.com/mambo//index.php?option=com_content&task=view&id=54&Itemid=42&limit=1&limitstart=4[/URL] [IMG]http://www.lostcircuits.com/cpu/amd_phenom_ii_am3/winidle.gif[/IMG] [B]Power Consumption under load[/B] looks different: Phenom IIs need less energy for the same computing task, followed by Phenom Is. the worst are Athlon X2s. = under the same load your 45W TPD X2xxxxe will need more energy as a "non-e", 65 or 95 or 125 W TPD Phenom II. for power efficiency check this out (2nd graph): [URL="http://www.lostcircuits.com/mambo//index.php?option=com_content&task=view&id=54&Itemid=42&limit=1&limitstart=6"]http://www.lostcircuits.com/mambo//index.php?option=com_content&task=view&id=54&Itemid=42&limit=1&limitstart=6[/URL] [B]For the same computing task a Phenom II (125W TPD!) needed less energy (4625 W) than the best X2 (5530 Watt, 65 nm Brisbane X2 with 45 W TPD!) [/B] [IMG]http://www.lostcircuits.com/cpu/amd_phenom_ii_am3/caljoule.gif[/IMG] So in real life best choice is a 45 nm Phenom II, second place is difficult to decide (if your HTPC is always on, long in idle, X2 is better, if you power it up only if you need and 1080i is important for you without GFX-Card, Phenom I is better). So if someone can, should wait for the cheap mainstream 45W Phenom IIs (X2, X3 or X4) But I don´t really understand the problem. You want to spare 10 USD electricity bill a year or what???
