The unlocked hex-core i5-8600K from Intel’s latest Coffee Lake generation of processors is the new flagship of the i5 series, succeeding the Kaby Lake quad-core i5-7600K. The 8th generation of processors brings the largest performance uplift since Sandy Bridge by adding more cores at each of the i3, i5 and i7 product lines. Like the other Coffee Lake processors, the i5-8600K is built upon optimized 14nm architecture, marginally improved upon from Kaby Lake and Skylake. The 8600K has a 95W TDP and a nominal stock clock of 3.6 GHz, which boosts to 4.1 GHz for all six cores, 4.2 GHz for dual/quad and 4.3 GHz for single core. Early benchmarks put the i5-8600K’s effective speed 15% ahead of the i5-7600K. A 50% increase in multi-core speed is explained by two additional cores and thanks to the quad-core clock bump from 4 GHz on the 7600K to 4.2 GHz on the 8600K there is also an additional 5% performance boost across all workloads. All Coffee Lake processors require a 300-series chipset, making a straight CPU upgrade unfeasible despite sharing the same socket as their Z270 predecessors. Even though most games still use less than 4 cores simultaneously, the i5-8600K is a great choice for gamers but for $80 less, the 8350K which is
faster than last years 7600K and only marginally weaker for gaming than the 8600K is certainly well worth considering as well. [Oct '17CPUPro]
The Intel Core i5-13500 offers an interesting mix of performance and value that will likely capture the attention of savvy PC builders providing its MSRP of $235 USD holds true. The 13500 features the same 6 P-cores and 8 E-cores as the i5-13600K, which currently retails for $320 USD. However, it has a lower boost clock frequency (4.8 GHz versus 5.1 GHz) and less cache (35.5 MB versus 44 MB) which translates to a 10% performance disadvantage against the 13600K. Nevertheless, paired with a B660 motherboard and inexpensive DDR4, the 20 thread i5-13500, is a very capable mid-range processor for both gaming and multi-threaded tasks. Compared to AMD’s similarly priced, hex-core Ryzen 5 7600 and 7600X, the 13500 offers better gaming and 50% faster multi-core performance which is particularly beneficial to workstation and professional users. Intel has completely priced AMD's 7000 series CPUs out of the rational market. Despite this, as long as Intel continues to sample and sponsor marketers that are mostly funded by AMD, they will struggle to win market share. [Jan '23CPUPro]
