The powerful Threadripper CPUs are the pinnacle of AMD's Ryzen processor series. They are aimed at professional content creators as well as enthusiasts and run on motherboards with AMD's X399 chipset. The high-end CPUs not only achieve impressive results in benchmark programs but are also more energy-efficient under full load compared to comparable Intel models. Everything about Threadripper is twice as large as previous Ryzen CPUs: the processor has double the number of cores and double the number of memory channels. Additionally, it offers full PCI-Express support with 64 lanes. Four of these connect to the chipset, while the remaining 60 can accommodate up to seven PCI-Express devices - for example, up to four graphics cards and three NVMe SSDs simultaneously. While other Ryzen CPUs support DDR4 memory in dual-channel mode, Threadripper supports quad-channel DDR4 with ECC. Thanks to AMD SenseMI Technology, the processor excels with adaptive performance. AMD SenseMI automatically boosts the processor to peak speed when the PC requires more power for demanding tasks. This means that performance is available when you need it, while keeping power consumption low during normal operation. To extract maximum performance from the Ryzen CPUs, the processors with the X suffix are equipped with the new XFR feature. XFR means that these CPUs automatically allow overclocking beyond the regular boost clock. The maximum clock rate adjusts according to the cooling solution used, whether it be air, water, or liquid nitrogen. With the AMD Ryzen Master tool, you can easily overclock the CPU thanks to its unlocked multiplier. In AMD Ryzen Master, you can also easily keep track of the temperature and much more.

Key specifications

Processor family

Number of processor cores

A multi-core processor (or chip-level multiprocessor, CMP) combines two or more independent cores (normally a CPU) into a single package composed of a single integrated circuit (IC), called a die, or more dies packaged together. A dual-core processor contains two cores, and a quad-core processor contains four cores.

Number of threads

Max. TDP

The thermal design power (TDP), sometimes called thermal design point, refers to the maximum amount of power the cooling system in a computer is required to dissipate. For example, a laptop's CPU cooling system may be designed for a 20 watt TDP, which means that it can dissipate up to 20 watts of heat without exceeding the maximum junction temperature for the computer chip. It can do this using an active cooling method such as a fan or any of the three passive cooling methods, convection, thermal radiation or conduction. Typically, a combination of methods is used. The TDP is typically not the most power the chip could ever draw, such as by a power virus, but rather the maximum power that it would draw when running "real applications". This ensures the computer will be able to handle essentially all applications without exceeding its thermal envelope, or requiring a cooling system for the maximum theoretical power (which would cost more but in favor of extra headroom for processing power).

L3 Cache

Another issue is the fundamental tradeoff between cache latency and hit rate. Larger caches have better hit rates but longer latency. To address this tradeoff, many computers use multiple levels of cache, with small fast caches backed up by larger slower caches.

Multi-level caches generally operate by checking the smallest Level 1 (L1) cache first; if it hits, the processor proceeds at high speed. If the smaller cache misses, the next larger cache (L2) is checked, and so on, before external memory is checked.

As the latency difference between main memory and the fastest cache has become larger, some processors have begun to utilize as many as three levels of on-chip cache.
