AMD Cuts Price of 3900X in response to Comet Lake

i keep seeing this come up all the time when ever there's an intel vs AMD


ELI5 IPC, know what the acronym stands for, but what benefits from a higher IPC vs what benefits from higher clock speed?

The easy, but oversimplified, way to think of IPC is how efficient the CPU is with clock cycles.  The better the IPC, the more it can do at once…similar in effect to having more cores.


Better IPC doesn't suffer in work loads like more cores do though, when frequency dependent things are taken into account (such as specific games).  In frequency reliant workloads though, frequency will still win out if the IPC on the higher frequency part isn't worse than the frequency increase.


Currently, Ryzen has both better IPC and more cores.  This is why it is objectively better at most everything now, though can still fall behind in some specific workloads or games that are super frequency dependent and also don't parallelize very well.


Ryzen doesn't generally (over)clock as large as intel Core does, largely because of the process node differences.  Larger processes (14nm vs 7nm) are easier to cram more power and frequency through before each portion of the processor affects what is next to it with various interferences (crashes/data corruption).  The down side to this is both in power needed/heat and silicon longevity.  So intel has been finding ways to crank power and frequency on their existing larger process, while playing games with time limits and similar to drop back to help with heat and silicon longevity, leveraging the only advantage they have right now…the ability to brute force frequency with power use.

A 360 AIO minimum. Not anywhere near cheap. Not when AMD CPU's work with a stock cooler

Care to tell me how Linus got temps in the 60s with a 280mm then?

Unlocked thing runs super hot but at stock with a little boost it's actually fairly cool.
