Features of 14th Generation Intel Core Processors

This section explains the features of the 14th generation Intel Core processors.

The main points, from performance improvements to differences from the 13th generation, are summarized in an easy-to-understand way.

The 14th Generation is a Minor Update of the 13th Generation

The 14th generation (Raptor Lake Refresh) is a minor update of the 13th generation “Raptor Lake,” so there are no major changes.

The architecture and basic design remain the same, so rather than a major change in manufacturing process, it is mainly a refinement.

Socket and Chipset Remain “LGA1700” and “600/700 Series”

The 14th generation uses the “LGA1700” socket and “600/700 series” chipsets.

Same as the 12th and 13th generations, so by updating the BIOS, existing motherboards can be used.

However, some entry-level models and older batches of motherboards may not support 14th generation CPUs.

Therefore, if upgrading from the 12th or 13th generation, check the motherboard’s “CPU support list” to confirm compatibility with the 14th generation.

About Performance Improvements

The specifications and performance are mostly refined versions of the previous generation, but when comparing details, the following differences can be seen:

• The maximum clock speed has increased by about 0.1 to 0.3GHz
• The base TDP of some models has decreased
• Core i7 models have 4 more E-cores
• Core i7 models have 4MB more L2 cache and 3MB more L3 cache

Other major specifications remain the same as the previous generation:

• Supports both DDR4 and DDR5 memory
• Integrated GPU is Intel UHD Graphics 770
• Lineup includes K/KF (unlocked), standard (no suffix), and power-saving (T series) models
• PCI Express configuration

Overall, there is no dramatic performance improvement, so if a recent CPU is already being used, there is little need to upgrade.

Specifications of 14th Generation Intel Core Processors

This section explains the specifications of the 14th generation Intel Core processors by grade.

Intel Core i9 Processors

The changes in Core i9 processor specifications from the previous generation are as follows:

• The maximum clock speed has increased by about 0.1 to 0.3GHz
• The base TDP of i9-14900K and i9-14900KF has decreased by 25W

The Intel Core i9 processors are the highest performance models in the 14th generation Intel Core CPU lineup, all featuring 24 cores (P-cores: 8 / E-cores: 16) and 32 threads.

Also, models that support Thermal Velocity Boost(*) can reach clock speeds over 6GHz.

*Thermal Velocity Boost is a type of automatic clock boost function found in some high-end CPUs since the 10th generation. When the CPU temperature and power allow, it operates at even higher clock speeds than normal turbo boost.

Thermal Velocity Boost can temporarily increase performance for tasks that require high performance for a short time (such as gaming, video processing, and benchmarks).

It is especially effective in PCs with high cooling performance, and the benefits are maximized when combined with high-performance CPU coolers or water cooling.

Intel Core i7 Processors

The changes in Core i7 processor specifications from the previous generation are as follows:

• The maximum clock speed has increased by about 0.1 to 0.2GHz
• 4 more E-cores
• 4MB more L2 cache and 3MB more L3 cache

The Intel Core i7 processors are high-performance models in the 14th generation Intel Core CPU lineup, all featuring 20 cores (P-cores: 8 / E-cores: 12) and 28 threads.

Although they do not support Thermal Velocity Boost, the maximum clock speed still exceeds 5GHz, making them suitable for demanding tasks.

Intel Core i5 Processors

The changes in Core i5 processor specifications from the previous generation are as follows.

• The maximum clock frequency increases by about 0.1 to 0.2 GHz

Intel Core i5 processors have many lineup options, but broadly there are two groups: models with a total of 14 cores (P-cores: 6 / E-cores: 8) and 20 threads, and models with a total of 10 cores (P-cores: 6 / E-cores: 4) and 16 threads.

In the 14th Gen, the Core i5 series is a balanced choice for performance and efficiency.

The price range is also very approachable, so cost performance is strong.

Intel Core i3 Processors

The changes in Core i3 processor specifications from the previous generation are as follows.

• The maximum clock frequency increases by about 0.1 to 0.2 GHz

Intel Core i3 processors all have a total of 4 cores (P-cores: 4 / E-cores: 0) and 8 threads, with no E-cores.

Performance is more modest than the higher series, but it is more than enough for everyday use and business tasks.

Benchmark Comparison of 14th Generation Intel Core Processors

This section compares various data for the 14th generation Intel Core processors.

Benchmark Scores

The benchmark scores are listed in descending order, and basically, the grades are grouped in the order of i9, i7, i5, and i3.

However, there are cases where a standard model of a higher grade is outperformed by a “K” model of a lower grade with a higher clock speed.

Also, the “T” models are power-saving versions, so their performance is lower in exchange for lower power consumption, and their scores are also lower in this comparison.

Cost Performance

Cost performance is calculated as the score per 100 yen, and the list is sorted in descending order of cost performance.

Overall, Core i5 and i7 models have high cost performance.

i9 models are very high performance, but their prices are also much higher, so from a cost performance perspective, they are not as good.

Therefore, if the performance of Core i5 or i7 is sufficient for the intended use, these grades are the most recommended.

However, if Core i7 is not enough for the intended use, then Core i9 is the choice, even if it is more expensive.

Recently, performance has improved a lot, so for most uses, Core i7 is probably enough.

Power Efficiency (Watt Performance)

Power efficiency is calculated as the score per maximum TDP, and the list is sorted in descending order of power efficiency.

Those who want to build a power-saving custom PC may find this information useful.

Many of the power-saving “T” models dominate the top of the list.

However, “T” models are not widely available on the market, so availability may be limited.

Summary: The 14th Generation is a Minor Update with No Major Changes

This article explained in detail the features, specifications, and benchmark results of the 14th generation Intel Core processors.

Here is a summary of the key points:

The 14th generation is a minor update of the 13th generation, with a slight increase in clock speed overall and more E-cores in Core i7 models, but no other major changes.

For those building a new custom PC, the 14th generation is a good option, but for those who have built a PC in the past few years and are considering an upgrade, it may be better to wait.
