Best CPUs of 2021

CPU (Central Processing Unit) is the PC’s brain. The most essential task is to perform calculations and process instructions provided by the applications and send commands to all components of the PC and I/O. As a result, CPUs have evolved a great deal over time. There used to be a single processor (core) inside the CPU for many years, but with the increase in processing demands and arrival of CPU-intensive games, one processor just wasn’t enough. It marked the start of a newer generation where we witnessed the best CPU development of all time. Multiple core CPUs became a new norm, and hyperthreading was introduced to allow more than one task to be performed by a single-core simultaneously.

There lies a fundamental philosophical difference between the selection of a gaming CPU or a professional CPU. The professional use of CPUs usually requires a more significant number of cores to process multiple threads and instructions simultaneously, achieving better results. On the other hand, CPU-intensive games often require higher clocks that need to be as close to the GPU frequency as possible. It results in lower latency and faster-synced processing between CPU and GPU for improved in-game performance. Furthermore, faster cache and lower IPC (Instructions/cycle) also improve the overall performance of the CPU that is beneficial both in games and in professional tasks like video editing, etc. Take a Look at our quick shopping tips. They will aid you in deciding the best CPU for gaming for unparalleled performance.

Quick Shopping Tips:

Core Count: The core count is very effective in multiplying the output of the CPU. But for most gamers, six cores is the minimum number of cores needed to run the top 2021 games on 1080p. Any more than that, and we will see only marginal performance improvements within games that lie in the category of enthusiasts and elite PC builders. Professional work like encoding and editing software requires even greater than eight cores to enhance their output.

Boost Frequency: As we mentioned earlier, the CPU feature that affects in-game performance the most is the PCU frequency. CPU manufacturers employ different techniques to boost this frequency as high as possible. For example, Intel turbo boost and thermal velocity boost technology allow the frequency to reach up to 130% of the base frequency if the thermals allow it. Similarly, AMD features Precision Boost 2 technology to raise the clock speed and push the CPU to run faster.

Overclocking: Gamers often aren’t satisfied with the stock CPU speeds. They prefer overclocking, which is raising CPU clocks beyond stock speeds to improve processing power. High-performance CPU coolers are often required to keep the CPU within an acceptable temperature band while overclocking. AMD processors have unlocked multipliers by default to allow swift overclocking via AMD Master overclocking software. On the other hand, Intel processors have separate K series processors with an unlocked multiplier and permit overclocking.

AMD or Intel: AMD and Intel are excellent CPU manufacturers and produce the best quality CPUs in the market. AMD has a higher market share among professionals and workstations because of its superior core count, lower performance to price ratio, and excellent multi-threading capability. On the other hand, Intel is more prevalent among gamers and overclockers because of its better in-game performance and outrageous boost frequencies that AMD has yet to match.

Who said AMD CPUs aren’t good for gaming? AMD Ryzen 3 processors are the ultimate example of excellent craftsmanship and cutting-edge technology that surpass others in gaming graphics. AMD Ryzen 9 5900X is the best gaming CPU available to the masses having the unique Zen 3 architecture and the most significant single-core boost compared to the previous generation.

People once believed that AMD is only good for professional software and content creation while gaming was linked with Intel processors. The 5900X, which is the best CPU for gaming right now, changed our perspective by achieving top benchmarks in multi-thread and single-core performance necessary for maximum gaming performance. Additionally, PCIe 4.0 integration doubled the bandwidth to 32GB/s, so modern higher bandwidth GPUs will never bottleneck the CPU.

So how did AMD manage to achieve such an impressive feat? AMD doubles the number of cores per die to reduce latency and allow access to twice as much cache to the individual cores (up to 32MBs of L3) than Zen 2 architecture. Ultimately this resulted in significantly faster core performance with the same amount of cache as the previous-gen 3900X. That is why the 5900X is quicker than the 3900X with a similar core and cache and is the best gaming processor for extreme gamers.
