AMD lost ground to Intel in essentially every area of the CPU market during the Bulldozer years. The company lost significant financial resources and had to sell its silicon fabs. With an uphill battle to remain in the processor market, AMD put its hopes on Ryzen.
The top end Ryzen processor, Ryzen 7 1800X, has eight CPU cores clocked at 3.6 GHz. The CPU can also accelerate up to 4.1 GHz in certain work loads. The eight cores are organized into two partitions. Each partition has 8MB of L3 cache, and each core has a dedicated 512KB L2 cache, a 64KB L1 instruction cache, and a 64KB L1 data cache. This gives the Ryzen 7 1800X a total of 16MB of L3, 4MB of L2, and 1MB of L1 cache.
In Ryzen, AMD implemented its first micro-op cache, which can store recently used instructions, improving performance and reducing pipeline stalls. Ryzen processors also support Hyper-Threading, which allows cores to handle two threads simultaneously. The company's processor debuts alongside the new AM4 socket, adding support for DDR4 RAM.
Ryzen 7 was closely followed up by its Ryzen 5 processors, which are created from semi-defective Ryzen 7 cores. Ryzen 5 is available in quad- and hexa-core variants and at similar clock speeds to Ryzen 7.
