hundred KS could still be radically different from other standpoints this also extends to GPUs so what does binning mean and what is the silicon lottery this is our minute science playlist and yes this is gonna take longer than a minute to finish when risin 7 launched the hype was real and although they were never really true gaming CPUs as in most games won't come anywhere close to fully leveraging 16 threads they offered a unique value proposition to those previously considering only i7s and Zeon's but AMD not only brought octa core CPUs to the mainstream they did the same thing with hexa core CPUs in the 1600 1600 X which are priced comparably to intel's I 5 CPUs what many aren't aware of though is the fact that risin 5 CPUs use the exact same die as Rison 7 counterparts meaning that if you were to disable sequential cores and opposing CC X's you could have a risin 5 CPU from Horizon 7 CPU that means similar IPC similar overclocked ability and similar power drop per core with respect to TDP thresholds so AMD's disabling cores and risin 5 and rising 3 CPUs but why not to save money of course but from an architectural perspective they're doing this because some cores aren't passing the mark think of this as a sort of inspection if a single die with 2 CC axes has six cores pass with flying colors and two that don't then the die will likely be thrown into the 16 Series pile from here the degree of metal vapor deposition and current leakage among other things will be used to further determine whether or not the die becomes arisin 5 1600 or 1600 X lithography with better overall structure will appropriately handle larger power draws so those will become 1600 X's with higher TDP s-- this is the bidding process of every CPU GPU manufacturer on the planet does this to some degree but what about our previous example with 277 hundred KS why can one overclock above 5 gigahertz with ease and low voltage and one barely touched 4.8 gigahertz and get extremely hot this is where the Silicon Lottery earns its name and four CPUs it applies when they're unlocked if you buy a 7700 K from an online vendor like Amazon or new egg your guess is as good as mine regarding overclock ability and resulting V core requirements this has to do with the very tiny imperfections within each die not all connections between transistors and caches memory are up to par resulting in varying degrees of latency and power loss in the form of heat if the inefficiency of a single core or complex is great enough then it will be quarantined and effectively disabled within the die but if latency is minimal it will be left intact and Silicon Lottery takes effect it answers the question how high can I overclock my CPU with said voltage now no two CPUs are alike so if you want to get really fine into detail which no you if I would ever let you do you could eventually narrow down each specific voltage for every CPU ever designed on the planet that means that every CPU will have a certain voltage at which it could reach a frequency and remain relatively stable this is typically regarded as binning when you hear it use it's referencing the silicon's degree of perfection until an AMD already do this by unlocking certain skews and disabling cores but graphics card manufacturers run the same analysis consider three EVGA graphics cards a GT X 1080 a6 3.0 a GTX 1080 super clock and in GTX 1084 the win the face a CX card has a boost clock of seventeen hundred and thirty three megahertz while the SC and for the windows 1847 in 1860 respectively by nature of how ebj bends its cards certain boards are grouped into any of these categories the ones that can clock higher are costlier as a result you're essentially paying for a better bin it's under the radar but it's actually pretty cool so if you want a car that can run stable at a higher frequency got to pay a little more for it kind of like capitalism on a small scale it's the same thing you do when you choose to forego a 7700 in favor of a 7700 K the 7700 K has a higher bin than the 7700 so if both chips were unlocked we should expect the k-series skew to overclock a bit higher as a bonus here you can actually pay a premium for CPUs that are prebend silicon lottery comm you'll pay a premium sure but the overclocked sassette voltages and settings are guaranteed according to their website if you liked this video be
