What are you coming from? If you have a desktop with i5 or above, and a high end graphics card (lets say like the GTX XX70 and up), then this will certainloy not be a solution in your case. It is the lowest end dual core i7 on the mobile segment, certainly not comparable to desktop quad cores. Even when raising the TDP above the warranty limit, you probably won’t beat the i7 7500U multithreaded performance which is about 25% better than the 7Y75 when both are optimized (link). And the i7 7500 performance is comparable to the desktop pentium G4560 (link).
So if you come from a desktop, have a lok at your CPU specs and usage, if the i7 7Y75 can’t even keep up with a high end pentium from the most budget friendly gaming rigs, than you have to make sure you are not having a regular workload on more than double the performance of that. I have no idea how CPU intensive mechatronics workloads are, but still worth watching for.
About the thunderbolt GPU: don’t forget that the GPU only gets 4 PCIe gen 3 lanes. So it will be bottlenecked (Linus tech tips did a review on it, and you need 8 PCIe gen 3 lanes to avoid bottlenecking a modern GPU). It isn’t a big bottleneck though, I can’t remember the figures but I thought it didn’t exceed 10% bottleneck. So pairing it with a high end VR-capable desktop GPU probably will affect the performance. And that is when we are talking about the thunderbolt actually getting the full bandwith. In most devices, the thunderbolt port is connected to the chipset and thus has to share the DMI3 bandwith with other chipset parts (like your SSD’s and HDD’s, your wifi, other USB ports) and that DMI3 has a marginally lower memory bandwidth than 4 PCIe gen 3 lanes. You can guess it, that bottleneck can get very high than. So I hope for you that the thunderbolt is connected to the CPU directly instead of the chipset, but I don’t know if Eve solved it this way with the V.
If the higher performance is needed, than I would suggest to do a SFF build, those are portable desktops that can pack even the ryzen R7 1800X and a GTX 1070 comfortably (although you have to make sure it gets good airflow when using it or you could have thermal throttling). Another solution is to try and find a laptop you find portably enough that has the hardware you need. Certainly if you would have to buy an eGPU dock (another 300$ at least), you can do a decent SFF build combined with a portably monitor or those USB monitors (asus has one of 15,6"). And an eGPU dock isn’t much smaller than those SFF desktops as far as I can see.
But if the 7Y75 is sufficient for your workloads, and you don’t need the best GPU performance, than the Eve V is unbeaten for your purpose!
