The i5-10400F is a six-core hyperthreaded CPU from Intel’s latest Comet Lake series of desktop processors. This 65 W CPU has single core and all core boost frequencies of 4.3 GHz and 4.0 GHz, respectively. Whilst the 10400F will require a new LGA1200 motherboard, such as the Z490, Intel have guaranteed that the next generation of Rocket Lake CPUs will also be compatible with this chipset. The 10400F is aimed at mid-tier gaming PC builds, and as such, ships with a cooler but without integrated graphics. Despite being officially launched in Q2 of 2020, at the time of writing, the 10400F is still not widely available. Compared to the similarly priced Ryzen 5 3600, the 10400F’s lower memory latency gives it the lead in gaming and effective speed benchmarks. Since the Ryzen architecture creates a gaming bottleneck, it is necessary to upgrade to a higher tier, Intel CPU for better gaming performance. On the other hand comparing the i5-10400F and the i3-10100 shows that the 10100 offers comparable gaming performance for 22% less money whilst also including integrated graphics. [Jun '20 CPUPro]

The Intel Core i3-4340 is a budget dual-core four threaded 4th generation Haswell processor released in Q3 2013. At the time of release it was the top end Haswell Core i3 chip – offering great value for money, performance and power efficiency. It scores a strong effective speed of 89% with its base clock of 3.6 GHz which means that users will experience smooth and fast performance with the majority of desktop applications. Its two cores and four virtual cores are adequate for most games. The i3-4340 features Intel HD Graphics 4600 which are probably okay for playing some older games in 720p and are comparable AMD integrated graphics (for example, on the AMD A10-5800k) when it comes to 3D gaming. But serious gamers will need to have enough money left over after purchasing the i3-4340 to spend on a stand alone GPU. [Nov '14 CPUPro]
