Laptop is faster than Desktop

I had been most confident that my desktop PC is much faster than my laptop or notebook.
Although I read a lot of benchmarks, and compared benchmarks between processors, I never compared them between desktop against laptops, because I was sure that desktops will win. Wrong.

My most powerful desktop is an AMD3+ socket FX8320, the second fastest in the family of 8 core processors built by AMD. The highest is FX8350. The absolute fastest is the power hungry FX9XXX but it is very expensive and consume too much power and is too hot.

Compare it to my second hand laptop, the Zbook 15, with i7-4800. The fastest is i7-4930 which this workstation is capable of. My Zbook is equipped with 32Gb of DDR3 1600 MHz RAM. My desktop was also equipped with 32Gb DDR3 RAM, at 1860 Mhz.

Look at the userbenchmark readings:

AMD FX-8320-RM 363 65,782 User benchmarks, average bench 51% Socket 942, 1 CPU, 4 cores, 8 threads Base clock 3.5 GHz, turbo 3.65 GHz (avg) Performing as expected (51st percentile)

Intel Core i7-4800MQ-RM 2,075 9,551 User benchmarks, average bench 61% U3E1, 1 CPU, 4 cores, 8 threads Base clock 2.7 GHz, turbo 3.3 GHz (avg) Performing as expected (54th percentile)

67.3% Good

SC Int 105 SC Float 107 SC Mixed 105 84% 106 Pts

QC Int 316 QC Float 287 QC Mixed 317 70% 306 Pts

MC Int 450 MC Float 464 MC Mixed 454 68% 456 Pts

Therefore the laptop is faster.

If I were to upgrade them to the highest: fx9590 vs i7-4910mx

Worse, desktop PCs CPUs consume more power, and higher frequency, and yet have much lower benchmark readings.
