The Intel i7-4771 is the same as the i7-4770 apart from a 100 MHz increase in base clock from 3.4 GHz to 3.5 GHz. In theory this increase will only impact multi-core workloads because both processors have the same turbo clock of 3.9 GHz which should be engaged during single and dual core workloads. On multi-core workloads the turbo needs to be disabled in order to maintain acceptable core temperatures and operating frequencies drop to base clock where the i7-4771 has a marginal 100 MHz or 2.9% advantage. In other words the two processors should be largely identical. Looking at the i7-4770 vs the i7-4771 benchmarks verifies this. Both the 4770 and 4771 are the current top end mainstream market leaders but for the vast majority of desktop users they are probably overkill as typical consumer use rarely requires more than two cores. [Mar '14 CPUPro]

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]
