Core i9 12900KS:

this processor is much faster than the normal core i9 12900k. In terms of performance, this processor beats almost every processor on this planet right now. Which is great. This processor is also more expensive than the normal base version.

Cinebench R23:

Cinebench R23 (Single-Core) 2363
Cinebench R23 (Multi-Core) 29223

For decent Gaming-Performance, you should make sure you are above 1000 Cinebench R23 Single-Core points, and this processor just smashed the other chipsets in the new record-breaking scores of Cinebench R23 Single-Core 2363. In 3D rendering the higher the Multi-Core Score. The better the performance you will see. Anything above 20k+ Multi-Core Points will boost the performance and will render complex scenes in less time. And this processor scores 29223. This will also help in gaming. As most of you will know that the more the single cores scores are the faster will it open and close the applications. The multicore will also help in rendering and in gaming. This processor has the speeds of whapping 5.5GHz and can be overclocked further with precautions.

Geekbench 5:

Geekbench 5 (Single-Core) 2118
Geekbench 5 (Multi-Core) 19603

Geekbench 5 Test system’s potential for gaming, image processing, and video editing with the Compute Benchmark. This also tests your GPU’s power with support for the CUDA, OpenCL, and Metal APIs. This processor scored the best in the Geekbench 5. This processor also beats some of the latest and most powerful processors with new record-breaking scores of single-cores and multi-core performance. The single-core scores are 2118, and the multi-core scores are 19603. As you guys know. The higher the Geek bench 5 score the higher performance of the processor. Geekbench 5 score that is twice as high will mean the processor is twice as powerful. Ranking of single-core processors by Geekbench 5 score performance worldwide 2022. As of March 2022, the Intel Core i9-12900K processor achieved the best single-core performance with a score of 1,998 from the Geekbench 5 benchmarking tests.


Vendor Intel
Released April 4, 2022
Type Desktop
instruction set x86-64
Codename Alder Lake-S
Model number i9-12900KS
Socket LGA-1700
Integrated GPU UHD Graphics 770

Core i9 12900K is a desktop processor produced by Intel. This processor supports the socket LGA-1700. This processor has 16 cores and 24 threads. The base clock frequency of the Intel Core i9 12900KS is 3400 MHz, but with the new Turbo Boost technology, it can go up to 5500MHz. The size of the L3 cache is whapping 30 MB. This chip has also integrated graphics Intel UHD Graphics 770. The instruction set architecture is based on x64 and can support x86. As the x64 will make more bandwidth then this x64 will be the best choice. This processor can be more powerful if you chose the right motherboard for it. Because this processor can be overclocked. But I would say no to overclocking because 5.5GHz is enough for today’s gaming and editing. This processor is so fast that it can beat some of the most powerful and latest processors. This processor also has some of the most amazing speeds.


Cores 16
Threads 24
Base Frequency 3.4 GHz
Turbo Boost Frequency 5.5 GHz
Bus frequency 100 MHz
Multiplier 34x
L1 Cache 64K (per core)
L2 Cache 14MB (shared)
L3 Cache 30MB (shared)
Unlocked Multiplier Yes

This chipset has 16 cores and 24 threads with a base clock of 3.4GHz and, a boost clock of 5.5GHz. The bus frequency is 100MHz. which will help PCI lanes in terms of performance. This processor is also unlocked with a multiplier of 32x. This will help in overclocking this processor with the right amount of power consumption. This processor has the fastest L1, L2, and L3 cache memories. The L1 cache memory is 64K per core which means 16 cores have their L1 cache memories. The L2 cache memory is 14MB but it’s shared with the Ram. The L3 cache memory is also 30MB which is also shared with the system. If you are looking for the best value processor then this Intel Core i9 12900KS is the best choice. In terms of gaming, this processor performs very great with good compatibility with the Nvidia GPU and with the AMD GPU. In terms of video editing and graphics rendering this processor also shows the best performance. Because of its base clock of 3.4GHz and the boost clock of 5.5GHz.

Power Consumption:

Fabrication process 10 nm
TDP 150 W
Max. temperature 100°C

This processor is based on 10Nm process fabrication. The TDP shows 125W of power consumption. This processor can also be overclocked. So, you can increase the voltage in the motherboard interface if the motherboard supports the unlocked processors. The most amazing fact about this processor is that the max temperature support of this processor is 100C which is awesome. You can play games as long as you want and this will not affect the speeds or any thermal throttling issues if you have a good CPU cooler or water cooler. Sometimes when this processor takes a bunch of loaded applications then the processor increases the speeds of each core to the needs. This increases power consumption, thus making the CPU hotter.

Integrated GPU:

Integrated Graphics Intel UHD Graphics 770
GPU Base Clock 300 MHz
GPU Boost Clock 1550 MHz
Shading Units 256
TMUs 16
ROPs 8
Execution Units 32
TGP 15 W

Unlike the AMD Ryzen processors, this processor also has integrated Graphics. Intel Core i9 12900KS has 256 shading units with a base clock of 300MHz and a boost clock of 1550MHz. there are also 16 TMUs and 8 ROPs which will help in a performance increase. There are also 32 Execution units. The TGP shows only 15W of power consumption. What basically TMUs are, are texture mapping unit components in modern graphics processing units. It helps in rotating, resizing, etc. ROPs or (Raster operation pipelines) are the rendering output unit. This processor also has a powerful enough GPU that you can play some games on it like Call of Duty Modern warfare 1, 2, 3, etc. the boost clock will help to stabilize the FPS in games.

Ram support:

Memory types DDR5-4800, DDR4-3200
Memory Size 128 GB
Max. Memory Channels 2
Max. Memory Bandwidth 76.8 GB/s
ECC Support No

 Intel Core i9 12900KS can support the DDR5 Ram with a memory frequency of 4800MHz, and DDR4 with 3200MHz. The max memory support of this Intel Core i9 12900KS is 128GB. The max memory channel support is also 2. The max memory bandwidth is 76.8 GB/s which is incredibly fast compared to AMD. There is no ECC support on this Intel Core i9 12900KS.

Gaming Experience:

This processor is a good option for gamers. Considering its capabilities, it performs well in almost any situation like editing, gaming, rendering, streaming, etc. So, if you are looking for a processor under $600 then I highly recommend to by this processor because it doesn’t have any alternatives. You got 12 cores, 24 threads, and a boost clock of 5.5GHz. This will play every game at high FPS with a good combination of Graphics card and Ram. You will see no issues in the performance unless there is a bottleneck. So, to avoid that, I will make complete another article on the best compatible Ram, storage, and GPU for this chipset. Just let me know in the comment.

So, this was my review of the Intel Core i9 12900KS. If you guys learned something new then make sure to check out my other articles in the review, as well as my YouTube channel.
