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.

AMD’s 16 core, 32 thread Ryzen Threadripper 1950X is finally here to seize the throne for high end desktop processors. The 1950X is the flagship of the Zen based Threadripper series which also includes the 12 core 1920X and the 8 core 1900X. The 1950X has a stock clock of 3.4 GHz increasing to a maximum single core boost of 4.0 GHz and features quad channel DDR4 and 64 PCI Express lanes. This processor is effectively two Ryzen 7 1800Xs glued together with Infinity Fabric (AMD’s scalable interconnecting technology), making the 1950X one of the physically largest CPUs on the consumer market. If you are considering this CPU, you will need a new X399 motherboard with a TR4 socket. Early benchmarks show the 1950X competing with Intel’s similarly priced i9-7900X. Whilst the 7900X has slightly higher single and quad core scores (10%-15%), the 1950X is around 35% faster for multi-core workloads. Content creators, and other core intensive task masters will not be disappointed. [Aug '17CPUPro]
