The i7-8700K is Intel’s latest, top of the range, 8th generation Coffee Lake processor. Like Kaby Lake and Sky Lake before that, Coffee Lake is based on Intel’s 14nm architecture which has been slightly optimized on each iteration. Following AMD’s modus operandi, Intel has upped the cores and threads across the range of their CPUs. In previous generations, a 6-core processor would have been a high-end desk-top (HEDT) processor, however the i7-8700K is the first Intel CPU with 6 cores and 12 threads to be classified (and priced) as a mainstream consumer processor. Specifically, the i7-8700K features a base clock speed of 3.7 GHz which boosts to 4.7 GHz (4.5 GHz for the previous generation i7-7700k), 12MB of smart (L3) cache and 2 channels of DDR4 RAM. The majority of the performance improvements over the 7th generation stem from the higher core count which results in a 50% increase in multi-core speed between the i7-7700k and i7-8700k. A new motherboard will need to be factored into the budget when upgrading to the 8700K as it requires a new Intel Z370 chipset which has supposedly been designed to better deliver power to CPUs with a greater number of cores. Also available in this latest release of CPUs is the 6 core 6 thread i5-8600k which is a more rational option (around $100 cheaper) for the vast majority of users that don’t require hyper-threading. Sandy bridge owners can finally justify an upgrade but with the next iteration of AMD's Zen architecture just around the corner the CPU market will be a lot faster moving now that Intel, once again, has to compete. ^{[Sep '17 CPUPro]}

The Intel Core i7-2370QM is a 2009 Sandy Bridge laptop CPU. With four physical cores and eight threads the 2370QM is able to handle single, dual and multi-core workloads equally well. Comparing the 2670QM and the 3630QM, its Ivy Bridge counterpart, shows that the newer Ivy Bridge processor is approximately 30% faster, has the same TDP (45 Watts) and shares a common socket (FCPGA988) with the 2370QM. An interesting comparison is between the 2670QM and the 2600K, these processors share the same micro-architecture (Sandy Bridge) yet the desktop 2600K is over 50% faster. The gap between Laptop and Desktop processors has been significantly narrowed in newer generations. ^{[Mar '14 CPUPro]}
