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]

AMD's new top-of-the-line Ryzen Threadripper is now here, boasting 32 cores at a base clock of 3.0Ghz and a boost of 4.2Ghz. On paper, it seems like a processor with tremendous value for money, with an MSRP of $1799, $200 less than Intel's top-end i9-7980XE, while offering 32 cores compared to the Intel's 18 cores. However, benchmarks show that this processor, despite its monstrous multi-core performance of over 4000 points in UserBenchmark and over 5000cb in Cinebench R15, real-world performance, especially in Windows 10 (due to Window's scheduler) is severely hampered by memory bandwidth limitations due to X399 only supporting Quad-channel ram (compared to EPYC's Octa-channel support). This means that only 2 of the 4 dies (16 cores) are directly connected to the RAM, while the remaining 2 dies have to go through the infinity fabric. Running the 2990WX on Linux improves its performance in some cases, but the memory bandwidth bottleneck is a hardware limitation. As such, in many real-world applications, the 2950X and the i9-7980XE beats the 2990WX, especially in memory intensive workloads and gaming. That being said, users should consider the 2950X, which is half the price of the 2990WX and in many applications outperforms the 2990WX. [Aug '18 geistrucker]
