I ordered the Kaby Lake i5-7200u version of this box for testing. Same exact processor, just 2 generations ahead. Should be around 20% faster factoring in the additional clock speed and Skylake architectural improvements.
There's only one network port in this model, the VGA port replaced the 2nd network port. If you remove the wireless card (as I did in the above picture) you can in theory install a mini pci express network card. Otherwise it's about the same design.
32GB RAM does work, but you need DDR3 SODIMMs of 16GB size which are quite expensive! I stuck with 8GB + 8GB.
I can definitely verify it sticks to fairly high clock speeds, even with 1 thread fully loaded with MPrime
sysbench -- 17.4s (multicore) 24s (single core)
4 thread → 2.8 GHz (36w)
2 thread → 2.9 Ghz (40w)
1 thread → 3.1 Ghz (23w)
I also have the same box with the Kaby Lake i7-7500u versus the i5-7200u:
sysbench -- 15.5s (multicore) 21s (single core)
4 thread → 3.3 GHz
2 thread → 3.4 Ghz
1 thread → 3.5 Ghz
The peak power is a little concerning as the i5-5200u box only went to 26w in the same circumstances.. but due to the AVX2 optimization in MPrime, I'm trusting it a little less as a real baseline of potential CPU load power usage these days..
