The results are ideal for both CPUs. The Core i7-12700H is a high-end gaming CPU that needs solid multi-core performance, which it delivers according to these tests.

On the other hand, the Core i7-1255U is a power-efficient CPU optimal for lighter workloads like web browsing and the occasional light gaming. For that, it has 8 efficiency cores (as many as the 12700H) and is not far behind the Core i7-12700H in single-core performance. 

Laptop Prices

Next, here’s how much the laptops cost for both CPUs. Note that the Core i7-12700H is a gaming-focused CPU, so the laptops using this chip can be a lot more expensive, depending on what you choose.

Most of the laptops have dedicated graphics cards for gaming. On the other hand, the Core i7-1255U is a power-efficient CPU aimed at lightweight laptops and light workloads. All the Core i7-1255U laptops you’ll find rely on the CPU’s integrated graphics.

The price data has been taken from Amazon US and is applicable as of July 2023

  • Core i7-12700H: The laptops start at $699 (for variants with no dedicated GPUs). However, the best sellers lie in the $1096 to $2399 range, while the most expensive Core i7-12700H laptop comes in at $5934.
  • Core i7-1255U: Entry-level laptops with this CPU start from $419. The most popular options are priced between $619 and $1100. Lastly, the priciest Core i7-1255U laptops can cost up to $2068.

Which CPU Provides Better Value? 

As both CPUs are aimed at different types of laptops and consumers, it’s hard to compare their values directly. They both serve their respective purposes. The Core i7-12700H is more expensive and is great for gaming with its multi-core performance. Contrastingly, the Core i7-1255U is part of Intel’s ultra-lower-power mobile CPU lineup for light laptops and notebooks. For this reason, laptops using this Intel CPU are also much cheaper. 

Which CPU Is Better For You?

This brings an end to my Core i7-12700H vs Core i7-1255U comparison. I’ve compared both CPUs in all the important aspects, including specifications, performance, and prices. As I’ve discussed above, both CPUs are excellent for their respective markets.

You should choose the CPU depending on your purpose. If you’re looking for high-performance and high-end gaming, the Core i7-12700H should be your choice. On the contrary, you should go for the Core i7-1255U if your workloads involve web browsing and light gaming. Furthermore, the Core i7-1255U laptops are good for tasks like graphic designing and running the Microsoft Office suite.
