Quick Buying Tips!

THREADS: A higher thread count means that the CPU can handle more tasks simultaneously as it has more pathways available for data transfer. In games, a CPU with higher thread count offer better performance in multi-threaded scenarios. However, the high thread count may not directly translate into better performance in all games. For example, some games are designed with a low number of cores/threads in mind while some others can benefit from higher core/thread count CPUs.

TDP: TDP is the maximum amount of power that a cooling system requires to dissipate from the CPU or GPU chip. Thermal Design Power or TDP represents how much cooling solution is necessary to cool down the CPU, therefore too much TDP means an over-sized heatsink and fan assembly which often leads to noise-related issues for smaller form factor PCs. On the other hand, too little TDP means an under-sized heatsink that wouldn’t be able handle extreme heat generated by more cores/threads.

CACHE: Cache memory offers the quickest access to data usually accessed by the processor frequently. You can think of cache memory as a type of gateway that intelligently decides which information should be stored in main system memory and which one should stay in the cache.

CPU COOLER: The cooler your CPU runs, the lesser thermal throttling you get during high-load scenarios. Thermal throttling is a process where a chip reduces its clock speeds or core voltage to reduce power consumption and heat generation if it exceeds a pre-determined temperature threshold marked as TjMax. For instance, Intel’s Coffee Lake CPUs throttle at 95°C/203°F while AMD’s Ryzen 7 2700X tops out at around 68°C/154°F.

CORES: The more cores you have, the better multi tasking performance on your CPU as it has more pathways available for data transfer between different tasks running simultaneously. However, core count alone is not enough to determine how good a processor is. For example, a quad core CPU from Intel will outperform a hexa-core CPU from AMD in single threaded applications.

BOTTLENECKING: A CPU bottleneck occurs when the processor is not powerful enough to process the tasks at hand efficiently. It might be due to insufficient core speeds or an inefficient architecture. Bottlenecking can also occur when the number of cores doesn’t match with the bandwidth available on your motherboard. For instance, you’ll need at least an Intel Z390 chipset to support 8 cores on Coffee Lake processors while you’ll require a X299 Motherboard for 18 core CPUs from Skylake X series . Bottlenecking is more common during gaming as most games are still mainly designed with 4-6 core CPUs in mind.
