i7-12700H vs i9-12900H: A Detailed Comparison

The Intel Core i7-12700H and Intel Core i9-12900H are both high-performance laptop processors that are part of Intel’s 12th gen Alder Lake family.

They are both based on the same hybrid architecture, which combines a combination of high-performance P-cores and efficient E-cores.

But which one is right for you?

Integrated GraphicsIntel UHD Graphics 740Intel UHD Graphics 770

As you can see, the i9-12900H has a slightly higher base clock speed and turbo boost max, as well as 6 MB more L3 cache.

The i9-12900H is also about 12% faster in multi-threaded workloads, which makes it a better choice for tasks that can utilize all of its cores.

However, the difference in performance is not always significant. In some cases, the Core i7-12700H may be just as fast as the Core i9-12900H.

This is especially true in single-threaded workloads, where the difference in clock speed is less important.

Performance Benchmarks

BenchmarkIntel Core i7-12700HIntel Core i9-12900H
Cinebench R23 (Multi-Core)1080012500
Geekbench 5 (Multi-Core)82009600
3DMark Time Spy85009200

In benchmarks, the Intel Core i9-12900H is about 7% faster than the Intel Core i7-12700H. This difference is most noticeable in multi-threaded workloads, such as video editing and 3D rendering.

For example, in the Geekbench 5 benchmark, the Intel Core i9-12900H scores 12,548 in the multi-core test, while the Intel Core i7-12700H scores 11,200. This is a difference of about 12%.

In real-world use, the difference in performance between the two processors is even less noticeable.

For example, in a game like Shadow of the Tomb Raider, the Intel Core i9-12900H averages 95 frames per second (fps), while the Intel Core i7-12700H averages 90 fps. This is a difference of just 5 fps.

Power Consumption

Both the Intel Core i7-12700H and the Core i9-12900H have a TDP of 45W to 115W. This means that they both consume a moderate amount of power.

However, the Intel Core i9-12900H is more likely to draw more power under heavy workloads due to its higher performance capabilities. This may be a consideration for users who prioritize battery life.

This is not a major concern for most laptops, as the battery life should still be sufficient for most tasks. However, if you are looking for a laptop with the longest possible battery life, the Intel Core i7-12700H is a better choice.


The Intel Core i9-12900H supports Intel Turbo Boost Max Technology 3.0, which allows it to boost its clock speed up to 5.0 GHz on a single core.

The Intel Core i7-12700H only supports Intel Turbo Boost Max Technology 2.0, which allows it to boost its clock speed up to 4.7 GHz on a single core.

The Intel Core i9-12900H also supports Intel Adaptive Control Technology, which allows it to automatically adjust its power consumption to optimize performance and efficiency. The Intel Core i7-12700H does not support Intel Adaptive Control Technology.


So, which processor is right for you? If you are a power user who needs the absolute best performance, then the Core i9-12900H is the way to go. However, if you are a more casual user or you are on a budget, then the Core i7-12700H is a great option.
