Jok. 3200C14 je "brže" od 3400C16 3400C15 bi bilo marginalno "brže" od 3200C14.

Ja sam viđao po netu suprotno, baš neki dan gledao za gaming, korak više brzina na cl16 je brže od koraka sporije na cl14. Samo se ne mogu sjetiti koji portal, kad nađem linkam (radilo se o 3600mhz cl16 vs 3400mhz cl14 ili 3400 cl16 vs 3200 cl14). U međuvremenu našao na drugome mjestu nešto slično, no radi se random benčevima ne o gamingu

This is rather surprising. The jump from DDR4-3200 CL14 to DDR4-3400 CL16, a 6.25% increase in not just DRAM, but also InfinityFabric clock, results in a negligible 0.65% performance increase. If you've read our first-generation Ryzen Memory Analysis article from last year, you'll know that the jump from DDR4-2133 to DDR4-3200 resulted in significant performance improvements of 3.1 percent (which is quite a lot for CPU-focused tests). The jump to 3400 MHz from 3200 MHz not being as great, it would be advisable not to pick up overpriced 3400 MHz Ryzen-friendly kits if 3200 MHz kits are cheaper.

Getting DDR4-3400 to work with CL14 isn't easy, and wasn't stable despite our best efforts. Even the G.Skill SniperX DDR4-3400 "Ryzen-friendly" kit we have at hand won't budge from CL16 at its advertised clocks. Please also note that 3400 MHz is running at CL16 (which is the fastest that's available). At 3400 MHz, CL16 is 8.89 nanoseconds (16/3200*2*1000), whereas the 3200 MHz kit is running at tighter absolute latencies of 8.75 nanoseconds, which gives a slight latency advantage to the 3200 MHz kit, while the 3400 MHz kit has the bandwidth and CCX-performance advantage.
