The Intel Core i7-920 is five and a half years old which puts it at an enormous disadvantage to more modern processors. The 920 sports four cores and eight threads which is the same basic configuration that Intel still uses in the majority of their i7s. Comparing the 920 to the 4770K, its modern day equivalent, shows that 920 lags by 63% at stock speeds and by 44% when both processors are overclocked. Overclocking improves the 920 by 30% vs just 17% for the 4770K. Aside from approximately 50% more calculation throughput the 4770K offers lower power consumption, compatibility with Intel's latest FCLGA1150 platform, on-board graphics and newer CPU instructions. Owners of the 920 should probably consider upgrading not only to improve system response times but also to take advantage of the newer platform. [Mar '14 CPUPro]

The Ryzen 7 5800X is one of four new processors from AMD’s latest range of Zen 3 CPUs. The new architecture is more power efficient than Zen 2 and also yields significant performance improvements. All four new CPUs have the ‘X’ nomenclature, indicating that they are tuned to their maximum clock speeds out-of-box. The 5800X has 8 cores and 16 threads with base/boost clock speeds of 3.8/4.7 GHz, 36 MB of cache and a 105W TDP. At $449 USD, the 5800X is relatively expensive, but it still offers far better value than the 5900X. A 500 series motherboard is recommended but the new Zen 3 CPUs will work with most 400 series motherboard following a BIOS update (expected in Q1 2021). At AMD’s launch presentation, they said they finally had the best CPUs for gaming. Our benchmarks show that the 5800X is comparable to Intel’s $175 USD 11400F. Gamers that do not wish to pay “marketing fees” can invest those savings in a better GPU which will produce an unquestionably faster gaming PC. [Nov '20 CPUPro]
