The DS50U7 barebone from Shuttle did impress us in terms of performance, considering we are talking about a fanless design. PL1 is limited to 15W, while PL2 is limited to 17W, while in the case of the ECS LIVA Z5 Plus with active cooling and the i5-1335U SoC, we noted PL1 set at 20W and PL2 set at 39W, which is considerably higher; despite that, we see the i7-1355U winning in some cases, due to the implementation of DDR5 memory, higher boost on the iGPU clock, more execution units, but also a higher boost on the CPU, helping quite a bit in low to medium loads, a situation which is frequently found when using the device like 90% of the time.
