Core Voltage: The Phenom Requires Just 1.20 Volts
The Phenom X3 8750 with 2.40 GHz provided by AMD uses a core voltage of just 1.20 volts. The missing processor core is obvious, the Phenom X4 9850 or 9750 with four cores requires a considerably higher voltage of 1.30 volts.
The Phenom X3 8750 manages with 1.20 volts.
The Phenom X4 9850 requires 0.10 volts more.
In comparison: The older Phenom X4 9600 with B2 stepping has a core voltage of 1.250 volts.
The Phenom X4 9600 needs 1.25 volts.
If the Phenom X3 is switched to the Cool’n’Quiet energy saving mode, the voltage, as with the Phenom X4 models, drops to 1.050 volts.
I still have faith the tide can always be turned, something you thought impossible with Pentium D vs AMD 64 X2. So it can happen again, if not I think we should make the EU take money from intel and give to AMD :P
Intel's interim solution was the Pentium D, which was basically taking two P4 and placing them on a chip. It didn't match AMD's performance, but it kept them in the hunt. AMD's response to conroe should have been the same; take two shrunken k8+x2 and place on a die. In this fashion they could have created some distance so that they could have come to a proactive solution to Intel's salvo.
Got this from AnandTech:
AMD doesn't have the resources to spin a dual-core Phenom die, so what better way of repurposing the quad-core die (especially if one core is defective) than to make a Phenom chip with less than four cores. Sure it's not the most efficient way to manufacture, but AMD doesn't have the luxury of producing a number of different Phenom die at this point. The triple-core Phenom strategy makes perfect sense if you're AMD, the question is: does it make sense if you're an end user?
I think you mean to say the small Phenom X3 model, the 8450.
I'd like to see the sony 'core' put into action other than yellow dogs lunix or Mercury's blader...sweeeet. They have six unit ps3's making 1 tflop @ 19k! :}
