Intel Core i7 12800H:

Cinebench R23:

Cinebench R23 (Single-Core) 1826
Cinebench R23 (Multi-Core) 15797

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 1826. 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 15797. 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 speeds of whopping 4.8GHz and can be overclocked further with precautions.

Geekbench 5:

Geekbench 5 (Single-Core) 1798
Geekbench 5 (Multi-Core) 12752

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-core and multi-core performance. The single core scores are 1798, and the multi-core scores are 12752. As you guys know. The higher the Geekbench 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.


Vendor Intel
Released January 4, 2022
Type Laptop
instruction set x86-64
Codename Alder Lake-H
Model number i7-12800H
Socket BGA-1744
Integrated GPU Iris Xe Graphics (96EU)

Intel Core i7 12800H is a Laptop processor produced by Intel. This processor supports the socket BGA-1744. This processor has 14 cores and 20 threads. The base clock frequency of the Intel Core i7 12800H is 2400MHz, but with the new Turbo Boost technology, it can go up to 4800MHz. The size of the L3 cache is a whopping 24 MB. This chip has also integrated graphics Iris Xe Graphics (96EU). 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 4.8GHz is enough for today’s gaming and for 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 14
Threads 20
Base Frequency 2.4 GHz
Turbo Boost Frequency 4.8 GHz
Bus frequency 100 MHz
Multiplier 24x
L1 Cache 80K (per core)
L2 Cache 1280K (per core)
L3 Cache 24MB (shared)
Unlocked Multiplier No

This chipset have 14 cores and 20 threads with a base clock of 2.4GHz and, with a boost clock of 4.8GHz. The bus frequency is 100MHz. which will help in PCI lanes in terms of performance. This processor is also unlocked with a multiplier of 24x. 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 14 cores has its own L1 cache memories. The L2 cache memory is 12MB but it’s shared with the Ram. The L3 cache memory is also 24MB which is also shared with the system. If you are looking for a best value processor then this Intel Core i7 12800H is the best choice. In terms of gaming this processor perform very great with good compatibility with the Nvidia GPU’s and with the AMD GPU’s. In terms of video editing and graphics rendering this processor also shows best performance. Because of its base clock of 2.4GHz and with the boost clock of 4.8GHz.

Power Consumption:

Fabrication process 10 nm
TDP 45 W
Max. temperature 100°C

This processor is based on 10Nm process fabrication. The TDP shows 45W 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 by the needs. This increases power consumption, thus making the CPU hotter.

Integrated GPU:

Integrated Graphics Intel Iris Xe Graphics (96EU)
GPU Base Clock 300 MHz
GPU Boost Clock 1400 MHz
Shading Units 768
TMUs 48
ROPs 24
Execution Units 96
TGP 15 W

Unlike the AMD Ryzen processors, this processor also has integrated Graphics. Intel Core i7 12800H has 768 shading units with a base clock of 300MHz and a boost clock of 1450MHz. there is also 48 TMUs and 24 ROPs which will help in a performance increase. There are also 96 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) is 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, LPDDR5-5200, LPDDR4x-4267
Memory Size 64 GB
Max. Memory Channels 2
ECC Support No

Intel Core i7 12800H can support the DDR5 Ram with a memory frequency of 4800MHz, and DDR4 with 3200MHz. the max memory support of this Intel Core i7 12800H is 128GB. The max memory channel support is also 2. The max memory bandwidth is also 64 GB/s which is incredibly fast compared to AMD. There is no ECC support on this Intel Core i7 12800H.

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, 20 threads, and a boost clock of 4.8GHz. 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 i7 12800H. If you guys learned something new then make sure to check out my other articles in the review, as well as my YouTube channel.
