The high-end hex core, 12 thread i7-8700 is second in Intel’s line up of 8th generation Coffee Lake CPUs that witnesses an increase in the number of cores at each SKU, as well as further refinement on the 14nm architecture as seen in the 6th and 7th generations. The i7-8700 features a TDP of 65W, 12MB of L3 Cache and 16 PCIe lanes. Although the 8700 has a base clock of 3.2 GHz it has an all core boost of 4.3 GHz and a single core boost of 4.6 GHz. These are unusually high clocks for a non-K SKU, Intel have historically clocked their non-K SKUs around 10% lower than the flagship K variants but with Coffee Lake, the 8700 is almost a match for a stock 8700K. Priced at $320, the i7-8700 offers exceptional single, quad and multi-core processing power to the mainstream market but unfortunately a new 300 series chipset will also need to be factored into the purchase. AMD’s comparably priced Ryzen 7 1700X is an 8 core 16 thread processor which is around 20% faster at multi-threaded tasks, but has around 20% slower single and quad core performance so the choice between these two processors is use case dependant but generally favours Intel for most desktop users whose workloads are typically single or dual core bound.  [Oct '17 CPUPro]

The Core i7-7700K is Intel’s flagship Kaby Lake based CPU which is reported to have the same IPC as its predecessor, Skylake. Comparing the 7700K and 6700K shows that both average effective speed and peak overclocked speed are up by 7%. Most of the increase in average effective speed is explained by the 5% boost in base clocks from 4.0 to 4.2 GHz. The improved peak lab speed is attributable to a combination of better overclocking capacity and improvements in Intel’s speedshift technology which make the 7700K slightly more responsive. Kaby Lake also has marginally better HD 630 integrated graphics. The i7-7700K is priced similarly to the i7-6700K so for top end gaming and workstation builds, the 7700K is the clear choice for 2017. AMD’s Ryzen will release later this year so things could change at that time. [Jan '17 CPUPro]

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]

Core i7-7700K - Intel

From WikiChip

Core i7-7700K - Intel

< intel‎ | core i7

Core i7-7700K is a 64-bit quad-core high-end performance x86 desktop microprocessor introduced by Intel in 2017. This processor, which is based on the Kaby Lake microarchitecture, is manufactured on Intel's improved 14nm+ process. The i7-7700K operates at 4.2 GHz with a TDP of 91 W and with a Turbo Boost frequency of 4.5 GHz for a single active core. This MPU supports up to 64 GiB of dual-channel non-ECC DDR4-2400 memory and incorporates Intel's HD Graphics 630 IGP operating at 350 MHz with a burst frequency of 1.15 GHz.

The Core i7-7700K is Intel's flagship mainstream processor based on Kaby Lake, succeeding the Core i7-6700K.

Cache[edit]

Main article: Kaby Lake § Cache

[Edit/Modify Cache Info]

Cache Organization Cache is a hardware component containing a relatively small and extremely fast memory designed to speed up the performance of a CPU by preparing ahead of time the data it needs to read from a relatively slower medium such as main memory.The organization and amount of cache can have a large impact on the performance, power consumption, die size, and consequently cost of the IC.Cache is specified by its size, number of sets, associativity, block size, sub-block size, and fetch and write-back policies.
