Pros And Cons

Core i7 12700H vs Core i7 1255U – Comparison Table

Architectural Differences

Let’s take a look at the architectural differences. 

1. Processing Node: Speaking of the fabrication nodes, the Intel i7-12700H and the Intel i7-1255U both enjoy the same fabrication node size of 10nm on Intel 7 processing technology.
2. Core/Thread Counts: The Core i7-12700H houses 14 cores in total, with 6 being P-cores and 8 being E-cores. In contrast, the power-efficient Core i7-1255U has 2 P-cores and 8-E cores for a total of 10. As for thread counts, the Core i7-12700H has 20 threads, and the Core i7-1255U has 12. 
3. Clock Speeds: The Core i7-12700H has greater base clock speeds for both P-cores (2.3GHz) and E-cores (1.7GHz). In comparison, the Core i7-1255U has a base frequency of 1.7GHz for the P-cores and 1.2GHz for the E-cores.
4. Cache: The Core i7-12700H has 24MB of L3 cache while the Core i7-1255U halves that at 12MB. Also, the Core i7-12700H has more total L1 and L2 cache counts due to its higher number of cores.
5. TDP: Lastly, the high-performance Core i7-12700H is much more power-consuming than the efficient Core i7-1255U. The Core i7-12700H has a base TDP configurable between 35 and 45 watts compared to only 12-15 watts of the Core i7-1255U. As for boost TDP, the Core i7-12700H can draw up to a massive 115 watts compared to 55 watts.

Intel’s Alder Lake CPUs brought a new revolution for them with their Hybrid Core architecture. Today, we’re comparing two mobile CPUs using this architecture in the form of Core-i7-12700H vs Core i7-1255U to find the better one. The two CPUs have numerous similarities, including L1 and L2 cache per core counts, boost frequencies, memory support, and the TjMax. Additionally, both use the same iGPU, but the Core i7-12700H’s iGPU boasts a higher boost clock speed.

Productivity Benchmarks

Now, how do the two CPUs perform, exactly? To find out, we’ll compare their multi-core and single-core scores across three different applications. 

Cinebench R23

• Starting with Cinebench R23, we observed that the Core i7-12700H racked up 16317 multi-core points. In contrast, the Core i7-1255U managed 8348 points. 
• Moving on to the single-core results, the Core i7-12700H scored 1802 points, and the Core i7-1255U is not far behind with 1665 points.

Geekbench 5

• The Core i7-12700H continues to dominate in Geekbench 5 with 12289 points in the multi-core test. In reply, the Core i7-1255U managed 7417 points.
• Concerning single-core performance, the Core i7-12700H, again, is just slightly ahead with 1744 points over 1647.

Passmark

• Wrapping things up with our Passmark’s benchmark, the Core i7-12700H accumulated 26848 multi-core points. The Core i7-1255U scored 13955 points in response. 
• As for the single-core test, the Core i7-12700H scored 3667 points, whereas the Core i7-1255U trailed slightly behind with 3401 points. 

Overall Performance

Here’s what the overall performance looks like across the three applications.

• Multi-core performance: The Core i7-12700H accumulated 18484 points over the three applications. In response, the Core i7-1255U scored 9906 points. Resultantly, the Core i7-12700H is a whopping 86.5% faster than the Core i7-1255U in our multi-core performance, on average. 
• Single-core Performance: The gap between the two CPUs is reduced for single-core scores. The Core i7-12700H averaged 2404 points, while the Core i7-1255U averaged 2237 points. Overall, the Core i7-12700H proved to be about 7.4% better in our single-core applications than the Core i7-1255U. The results are ideal for both CPUs. 

Core i7 12700H vs Core i7 1255U – Which CPU Is Better For You?

Intel Core i7 12700H: According to our examinations, the Core i7-12700H is a premium gaming CPU, excelling in multi-core performance. It’s pricier but ideal for gaming enthusiasts due to its gaming-focused design. It has also been observed that laptops with this CPU can vary significantly in price depending on configuration.

Intel Core i7-1255U: As for the Core i7-1255U, we ascertain it to be great for web browsing and light gaming with integrated graphics, part of Intel’s ultra-low-power mobile CPU lineup, offering affordability and decent single-core performance. We deem it ideal for users prioritizing battery life and affordability in laptops.

If you’re looking for high-performance and high-end gaming, we suggest the Core i7-12700H. On the contrary, we advise that 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.
