Ryzen vs FX?
Reviewed this discussion after coming back, I thought about it—like comparing a Ryzen 3100 versus 3300X, right? If you remember the differences...
Essentially, Ryzen per-core access grants full resource usage, whereas the FX series had to divide its resources, such as the FPU, among multiple cores.
The Ryzen 3 3100 and 3300X stand out as special processors. Each Zen 2 CCX contains four cores, but there are two CCXs per CCD. The 3100 uses two CCXs with two cores each, leading to increased latency since tasks needing more than two cores must split between the two (often called a 2+2 setup). Additionally, each CCX holds only half the cache of a full CCX, which hurts performance in cache-heavy and latency-sensitive jobs. The 3300X features a single CCX on one CCD (a 4+0 layout), offering superior core-to-core and cache latency compared to other Zen 2 chips. This design made the 3300X an excellent budget gaming option, sometimes outperforming the higher core count 3600. The Bulldozer module’s complexity contributed to its failure, largely due to shared resources being a major drawback.
