The Intel Core i7-3960X is a high-end desktop processor of the Sandy-Bridge-E series with 6 processor cores and 15 MB level 3 cache. It offers no integrated graphics card and the TDP of 130 Watt suites the CPU only for large desktops. The integrated quad-channel DDR3-1600 memory controller supports up to 64 GB RAM.
Thanks to the six cores, the performance in theoretical benchmarks is clearly above the fastest Ivy-Bridge and Haswell quad cores. However, in applications and games that wont use all six cores, these consumer CPUs are usually faster.
The first C1 stepping of the CPU had no support for VT-d virtualization, later edition do however.
The Intel Xeon E-2276M is a high-end processor for professional laptops with six cores based on the Coffee Lake architecture. The processor clocks at between 2.8 - 4.7 GHz and can execute up to twelve threads simultaneously thanks to Hyper-Threading / SMT. According to Intel, the CPU is manufactured in an improved 14nm (14nm++) process. Compared to the similar consumer Core i7-9850H, the mobile Xeon offers support for ECC main memory and clocks 100-200 MHz higher.
The Coffee Lake architecture is similar to Kaby Lake and differs only in the amount of cores (now six cores for the high end versions) and the improved 14nm process (14nm++ according to Intel).
Performance
The Xeon E-2276M is a high end processor in 2019 and therefore well suited for all tasks. Thanks to the high Turbo Boost, the single core performance is also very good. Long term performance however is very depending on good cooling and proper TDP settings and differs therefore for each laptop.
