Independent benchmarks: Intel Core 2 Duo (Conroe) 2.67 GHz

“While in Taiwan for Computex this month someone dropped an engineering sample of a Conroe processor in my pocket. After getting home and getting some motherboards in with Conroe support, I set out to test this CPU and see what numbers Intel was preparing for enthusiasts in July,” Ryan Shrout reports for PC Perspective.

“If you didn’t know any better, the processor below would appear to be just another LGA775 Pentium processor we have played with numerous times. The fact that the face has been lapped clean should indicate that someone didn’t want us to find out where it came from, but regardless, what we have here is an engineering sample of the upcoming Conroe core processor. Intel has already officially announced the name of the upcoming desktop branding for these processors, the Intel Core 2 Duo processor,” Shrout reports.

“Loading up the latest version of CPU-Z, we see that we have a Conroe processor running at 2.67 GHz, with a model number of Core 2 Duo E6700. According to information circulating around the web, this will be the top speed grade of the Core 2 Duo processors; though there will be a 2.93 GHz Core 2 Duo Extreme Edition CPU released as well,” Shrout reports. “These processors are built on the 65nm technology that Intel has been ramping up, with a 266 MHz quad-pumped front side bus for a total bus speed of 1066 MHz.”

“In our results, the idle wattage on the Conroe is actually higher than the Intel 965 and AMD Athlon FX-62 processor — a clear indication that our reference board isn’t doing something right. Chances are our reference platform is doing something incorrectly in terms of power management, so we’ll dismiss those idle results for now. What is worth looking at is the load wattage result — 186 watts on the E6700 vs. 256 watts on the AMD FX-62 processor! Keeping in mind that the performance on the E6700 was almost always HIGHER than the FX-62, you can do that math to see that Conroe is blowing the X2 processors out of the water in terms of performance per watt,” Shrout reports.

“AMD is going to be in more than a bit of trouble come the end of July if they don’t have an answer to Intel’s Core 2 Duo product line. The E6700 sample we tested with here was able to trounce the FX-62 in many cases, and came out the leader in nearly every test we threw at it,” Shrout reports. “The Core 2 Duo E6700 tested here simply swept through the benchmarks, leaving everything in its wake; I can’t wait to run an X6800 through the paces to see how it performs.”

  1. More here guys!!

    According to the thread and pictures:

    Release date by Intel in volume by Jan 2007

    Air cooled, with no fan 95-100ºF

    Cinebench 2003 Multiple CPU Render Test – “Daylight” – 16 seconds!

    My estimation of the “Mac Pro” lineup will be like past lineups:

    Single 1.6, 1.8 Dual 2 (when PowerMac G5 first released)

    Dual 2, Dual 2.3, Quad (present)

    Estimated future lineup:

    Quad X ghz, Quad X ghz, Dual Quad X ghz $$$ (most likely $6000)

    fan cooled?, fan cooled?, liquid cooled.

  2. Ok guys my link above is for the Kensfield which is a Dual dual-core Conroe, a Quad processor.

    Seriously dudes, lose the inline text ads. They sucks

    Simple remedy: sudo pico /etc/hosts, arrow to the bottom and add:

    control X, Y and press return.

    You can learn how to block your computer from accessing servers easily online, just search for editing hosts file.

  3. It does not fit into Apple´s plan to release new processors in their computers as fast as Intel brings out new ones.

    Watch and see that soon the Windows computer makers will be using faster versions than Apple. This is where Dell will excel. Apple has everything coordinated to fit into Steve´s trade fair schedule.

  4. Static Mesh: I use the hosts file thingie a lot, but never thought of using it for the intellitxt junk. Thanks.

    Now, about power….
    My Quad draws 253 watts at idle, and I’ve seen it go as high as 340 when Quicktime is encoding several movies at once. That’s for the entire computer – the G5’s, the 7800 graphics card, 4.5GB of memory, 2 drives, and several things powered from firewire & USB. So to put this article into perspective, these 4 cores here are consuming probably close to 186 watts, about what the dual core Conroe is consuming. I’m waiting for someone to benchmark the Conroe against a Quad. I’m not too impressed with it’s power consumption and I doubt if I’ll be left in its wake either.

  5. HAL,

    I disagree to some degree. If you notice that the new processors are compatible with each other’s socket and chipset. Apple probably mandated that. Look at how a test CPU can be put into a mac mini and still work. Apple can simply upgrade the chipset software and keep the motherboard with each upgrade of CPU.

  6. Apple can simply upgrade the chipset software and keep the motherboard with each upgrade of CPU.

    The problem with that is so can millions of savy Mac users, that’s going to eat into Apple’s hardware sales quite a bit.

    I would love to upgrade my duallie 2 to a Quad for a few hundred bucks.

  7. “The problem with that is so can millions of savy Mac users, that’s going to eat into Apple’s hardware sales quite a bit.”

    Not if Apple solders the chips into the motherboard like they have with the Macbooks and Macbook Pros.

  8. Ok, going by Cinebench multiple cpu rendering scores.

    Kensfield (Quad core Intel) – 1649

    PPC Quad (dual Dual Core 2.5 Gz) – 1016

    This means the Kensfield Quad processor is about 60% faster than the PowerMac G5 Quad.

    Of course a Octo-Core Mac Pro would be really smoking.
