Work is offering the option of upgrading my laptop. Unfortunately I'm not sure if it is an upgrade on the CPU side. Right now I have the Core i7-4810MQ.
Per Intel ARK (https://ark.intel.com/products/78937/In ... o-3_80-GHz
4 core, 8 thread. 2.8Ghz boost to 3.8. 22nm. 6MB cache, 5GT bus speed, 47W TDP. DDR3 dual-channel, 25GB/s. Intel HD4600 up to 1.3Ghz.
The best cpu in the new options is the Core i7-7600u, which is Kaby Lake.
2 core, 4 thread. 2.8Ghz boost to 3.9. 14nm. 4MB cache, 4GT bus speed, 15W TDP. DDR4 dual-channel, 34GB/s. Intel HD620 up to 1.3Ghz.
On most of those specs, it is actually a downgrade on everything except memory bandwidth. The only thing I don't know is if the 3 generations will overcome the other performances changes. My use case is all office-work, but I run the crap out of Excel calculations that frequency take 10+ minutes to run/calculate. I'm leaning towards having fewer cores would run slower.
I wish they would offer the quad Kaby then it would be a no-brainer, but Lenovo saw fit to not offer than on anything but DTR's. I'd go for even the i5-7440HQ, but alas.
