General info
Small semiconductors provide better performance and reduced power consumption. Chipsets with a higher number of transistors, semiconductor components of electronic devices, offer more computational power. A small form factor allows more transistors to fit on a chip, therefore increasing its performance.

Performance
1.CPU speed
8 x 3.2GHz & 8 x 2.4GHz
The CPU speed indicates how many processing cycles per second can be executed by a CPU, considering all of its cores (processing units). It is calculated by adding the clock rates of each core or, in the case of multi-core processors employing different microarchitectures, of each group of cores.
More threads result in faster performance and better multitasking.

2.maximum memory bandwidth
76.8GB/s
This is the maximum rate that data can be read from or stored into memory.
DDR (Double Data Rate) memory is the most common type of RAM. Newer versions of DDR memory support higher maximum speeds and are more energy-efficient.
More memory channels increases the speed of data transfer between the memory and the CPU.
The maximum amount of memory (RAM) supported.
6.bus transfer rate
Unknown. Help us by suggesting a value.
The bus is responsible for transferring data between different components of a computer or device.
7.Supports ECC memory
✖Intel Core i9-12900K
Error-correcting code memory can detect and correct data corruption. It is used when is it essential to avoid corruption, such as scientific computing or when running a server.
8.eMMC version
Unknown. Help us by suggesting a value.
A higher version of eMMC allows faster memory interfaces, having a positive effect on the performance of a device. For example, when transferring files from your computer to the internal storage over USB.
9.bus speed
Unknown. Help us by suggesting a value.
The bus is responsible for transferring data between different components of a computer or device.

ONE OF THE BEST CPU EVER FOR PERFORMANCE(by intel)

PLESE READ THIS , THIS WOULD BE HELPFUL FOR PLANNING TO BUY A GOOD CPU ! INTEL CORE i9-12900K is only behind the new and upgraded i9-12900KS ( which is 300$ more and don't worth it that much more). To me its the best chipset for anything I wanna do because its such a all-rounder . IT IS MORE POWERFUL THAN AMD's RYZEN 9-5900X OR 5950X ! . It smartly manages work load by using its efficiency cores to do less strain full works and save power and performance cores to do high strained works , which is pretty sick if you ask me :) . And finally for those people who think that it's way too power hungry , it isn't . When we compare i9-12900K side-by-side to our AMD' 9 5900X and 9 5950X boys : At Blender-gooseberry benchmarking ---- our intel boy was drawing out ABOUT 250W OF POWER ! , while our AMD boys were at about 150 W . BUT,...... AT GAMING (F1 2021) ---- Intel BOI was WITHIN THE BASE POWER OF 125 W averaging about at 100 W . BUT ON THE OTHER HAND ,........ Our AMD Boys WERE DRAWING MORE POWER THAN INTEL BOI . Man these Efficiency cores packs a punch , turns out Gaming isn't enough to push these to their limits as it is manageable by efficiency cores while benchmarks are made to push CPU's to their absolute limits and that much performance would come at least at a cost of that power. And it definitely gets too hot when that much electricity is used up in that tiny little thing , so , do buy some serious cooling system to pair with it . OR OR OR OR Trust me your are never gonna lose if you're choosing AMD or Intel , but to choose one , here is some tip :- + Intel chips have more powerful cores + AMD have less good cores than Intel but makes it up by have having more cores # CONCLUSION : Intel have adequate number of cores most program (including serious games) can use at max but AMD has so many cores that a program rarely or doesn't use all of the cores ( unless you are doing 3D rendering and blending stuff which would benefit from more cores ) and we know that Intel has far better cores than AMD , so for me the Winner is Intel . FINALLY IF YOU'RE READY TO SPEND SOME MONEY ON A GREAT COOLING SYSTEM FOR YOUR PC THEN THIS CPU IS A BIG YES FOR ME ! ( I hope this was helpful to who ever is reading it this FAR XD , Bye )
