<p>In Geekbench 4:</p>
<p>6 Core got about 14.000 points<br>
12 Core got barely 19.000 points</p>
<p>I was expecting around 28.000 or with some loss 27.000 - it is stunning 8000 points less - this is the speed of the latest MacBook Pro 13 TouchBar.</p></div>Barttag:support.primatelabs.com,2011-01-31:Comment/453504152018-05-25T17:05:08Z2018-05-25T17:05:08ZMac Pro 2009 12 core slow vs 2009 6 core<div><p>Hi,</p>
<p>Thanks for reaching out to us about this. Geekbench 4's Multi-Core CPU scores are not expected to scale linearly with the number of cores in a device, as core scheduling, inter-core communication, and cache behaviour can have a substantial effect on the device's measured performance.</p>
<p>I'm not able to find specifications for the Mac Pro 2009 with a 12-core X5670 -- is this the Mac Pro 2010, or am I perhaps looking in the wrong place? The average Multi-Core CPU score for the Mac Pro 2010 with a 12-core X5670 (available <a href="https://browser.geekbench.com/macs/265">here</a>) is similar to to your result, if that is the case.</p>
<p>All the best,<br>
