Early Q3 of 2019 welcomes the Ryzen 9 3900X, AMD’s current top of the range, third generation Ryzen flagship which is setting a new standard for high-end workstation processors. This is AMD’s first Ryzen 9 processor and is a 12-core, 24-thread CPU based on their latest 7nm Zen 2 microarchitecture. A second Ryzen 9 CPU in the form of the 16-core, 32-thread 3950X is expected around early Q4 of 2019. The 3900X has a boost/base clock of 3.8/4.6 GHz, 64 MB of L3 cache (double the L3 on the rest of 3000 series), support for 3200 MHz DDR4 system memory and a TDP of 105W. All this, plus a Wraith Prism cooler, at a relatively accessible launch price of $499 USD. By comparison, Intel’s coolerless 12-core, 24 thread i9-9920X is currently available for $1200 USD which is well over twice as expensive as the 3900X. Early benchmarks illustrate that the extra dollar spend does not translate to extra performance, with the i9-9920X having just a 4% greater peak overclocked benchmark than the 3900X across single, quad and multi-core workloads. Currently in terms of multi-core performance at this price point, there is no threat from Intel. The only real competitor is the upcoming 16-core, 32-thread 3950X ($749 USD) or possibly the slightly more affordable (but significantly worse value for money) 8-core, 16-thread Ryzen 7 3800X ($399 USD) which sits just below in the new Zen 2 line-up. Like the others in the 3000 series, the Ryzen 9 3900X can plug into the new PCIe 4.0 enabled X570 motherboard via an AM4 socket, as well as 400 and 300 series motherboards. [Jul '19 CPUPro]

The i5-8400 is a competitively priced hex-core processor from Intel’s 8th generation of Core processors (Coffee Lake). Along with the release of the unlocked i5-8600K, this is the first time that six-core processors have featured in the i5 line-up. Like the other Coffee Lake processors, the i5-8400 is based upon an improved version of Intel’s 14nm architecture which featured in both Skylake and Kaby Lake. Early benchmarks reveal that for average quad core usage (most games employ a maximum of four cores) the i5-8400 performs way above its pay grade. It achieves quad core mixed speeds close to Intel’s outgoing 2017 flagship the $300, quad-core, 8 thread i7-7700k, which to date has been a strong favourite for high-end gaming setups. On paper, the i5-8400 has a base clock of 2.8 GHz (Intel are significantly downplaying the performance of this SKU by giving it a relatively low nominal base clock), an all core boost of 3.8 GHz (this is the effective base clock figure that counts) and a single core boost of 4 GHz. This compares reasonably well to the i5-8600K which has a base clock of 3.6 GHz, all core boost of 4.1 GHz and a single core boost of 4.3 GHz. The i5-8400 also features 9MB of L3 cache and an energy-thrifty TDP of 65W. Priced at under $190, the i5-8400 offers fantastic value for money. Unfortunately, like the other Coffee Lake processors, the i5-8400 will require a new 300 series motherboard, and at the time of writing, the only available version is Intel’s high-end Z370 which isn't an ideal pairing for the i5-8400. The Z series motherboards are designed to cater for the unlocked and overclockable "K" SKUs. Cheaper 300 series motherboards will be available in 2018 at which time the 8400 will offer even better value for money. [Oct '17 CPUPro]
