The Intel Core i3-4350 is a refreshed version of the Haswell i3-4330. The newer i3-4350 has received a 100 MHz increase in clock speed which translates to a performance improvement of 2.8%. With an effective speed of 93.5 the i3-4350 is no slouch and offers performance that's slightly above the average of the ten group leaders. Similar to the G3258, the 4350 has a performance profile which favours single and dual core workloads. Comparing the G3258 and 4350 shows that not only does the G3258 offer far better overclocked performance but it also costs less than half as much as the i3-4350. Although the i3-4350 is not a bad processor, there are relatively few use cases that would justify its price when compared to the stellar G3258. [Jul '14 CPUPro]

MORE DETAILS

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]
