The World's First 65 W Desktop Quad Core

Phenom 9100e in Focus

Like all Phenom CPUs, the 9100e is also produced via a 65 nm process. In terms of technical features, it is completely identical to the conventional Phenom X4 CPU; the only differences are clock rates and the supply voltage. On the low-power Phenom, the speed of the memory controller and Hypertransport protocol has been set to 1600 MHz. The standard Phenom X4 runs these components at 1800 MHz, while the Phenom X4 9850 Black Edition has a clock rate of 2000 MHz.

The low-power model does not have an unlocked multiplier.

    People can still play games with this quad core. Sure, it's not as fast as a quad core from Intel, but it's evidently more than suitable to handle today's games. However, for about $200 it's a horrible value.

  • Just a quick question... at 1.8GHz is this chip even competitive with a higher speed dual core (even when considering 4 core vs 2 and considering multi-core optimized applications)?

    It'd be interesting to add in a Intel mid to high range dual core and look at the power consumption and performance vs the relatively low clocked quad. Dropping the clockspeed so low would seem to give back most of the games from having 2 extra cores (and would be worse for SW that cannot use 4 cores).

    Im an Q9450 owner and to just drop the multipler on the QX9770 and use the same vid isent fair.
    My Q9450 VID = 1.1v, EIST drops VID to 1.0375v

    I bet thats gonna make it hard for the phenom to beat

    Page 12 title is wrong. It's 9.8% not 8.8%. Just mention it, as it seems no one's noticed it yet.

    This just goes to show how crappy "Barceloney" really is.

    Consider the fact that one can buy an e8400 or 8500 which uses the same power, can keep up with AMD's quad cores (even when they are over clocked), and also DESTROY this thing at gaming. WHY exactly would I buy this piece of crap again Frank ?!?!

    I guess if I ran Cinebench benchmarks all day and did NOTHING else, then this cpu would look good.

    People that buy quad cores are not going to care about 35 watts, they want to brag about speed OR get their work done ASAP, and AMD is crap for that right now !

    An excellent review Frank ... well done.

    Very impartial ... showing the strength's and weaknesses of the low power unit.

    The overclocking limit of 2.4 would be interesting to explore further.

    Can you elaborate on what settings you went to ... and the HTT frequency please?

    Cheers,

    Why did you underclock the l3 cache and memory controller? The ht link is ment to be overclocked, not underclocked! L3 runs the same speed as ht link not 2,4 ghz. Slow L3 is a big bottleneck in games.

    comparing power consumption of a 1.8ghz phenom with a stock q6600 and touting the phenom as the power consumption king is a very inaccurate conclusion. The articles here just keep getting worse and worse... seriously who hires these clowns?
