CasecutterIt hardly mattered as those weren't a appropriate purchases for entry 4K, except with a game or two.

cdawallI have played 4K without issues on a single 390, the vast majority of games comfortably play at >40FPS at 4K and medium/high settings. Turns out you can actually enjoy games without setting everything to max.

TheGuruStudHeresy! Heathen! Sodomite!

Dirty Console Peasant! :roll:

cdawallHey now I didn't say medium settings at 720P/1080P

BiggieShadyWho knows what he meant, but you're wrong, same instruction set, different micro architectures (and architectures both) cpus can have their instructions per clock count (IPC) compared.
Name says it all, how many x86/x64 instructions by average can a single core execute in a single clock tick (you do that measurement actually on a gazillion clock ticks then divide result with gazillion).
You gotta remember these are super scalar processors and single core is capable of issuing multiple less wide instructions simultaneously and some instructions read from different cache levels with different latencies, some from memory, some just process the instruction operands ... so scheduler has to calculate dependency and arrange mutually non-dependent short running and long running instructions of different instruction widths to execute in parallel (on that single core) in a way that at any given time maximum possible usage of all units is achieved (for example, doing several ALU instructions on cache while waiting on fetch from a memory controller).
You have a myriad of different algorithms there so every little optimization in cache, memory controller, branch prediction, pipeline depth reduction will certainly affect IPC. The whole architecture including the micro architecture.
