Intel Core i5-14400 vs Intel Core i5-14600T Comparison

The Intel Core i5-14600T and Intel Core i5-14400 are two desktop processors from the same Core 14th Gen family, both built on the Raptor Lake architecture and sharing the Intel Socket 1700. The database shows a clear overall winner, but the individual benchmark results reveal a more nuanced story, with the lower-power chip actually leading in a couple of specific workloads. This analysis breaks down the recorded data to see where each processor excels and what the numbers imply for different usage scenarios.

FAQ

Q: Which processor has more cores and threads?

A: The Intel Core i5-14600T has 14 cores and 20 threads, while the Intel Core i5-14400 has 10 cores and 16 threads. This difference in core count is a fundamental factor in their multi-threaded performance.

Q: What are the clock speed differences between the two?

A: The Intel Core i5-14600T has a base clock of 1.80 GHz and a boost clock of 5.10 GHz. The Intel Core i5-14400 has a higher base clock of 2.50 GHz but a lower boost clock of 4.70 GHz. The 14600T relies on a lower idle speed but a higher maximum frequency.

Q: How do their TDP ratings compare?

A: The Intel Core i5-14600T has a TDP of 35 watts, which is significantly lower than the Intel Core i5-14400's 65 watts. This suggests the 14600T is designed for more power-efficient systems despite its higher boost clock.

Q: Which processor has a larger L3 cache?

A: The Intel Core i5-14600T has a larger shared L3 cache at 24 MB, compared to the 20 MB on the Intel Core i5-14400. The 14600T also has a larger L2 cache per core at 2 MB, versus 1.25 MB on the 14400.

Q: Do they feature different integrated graphics?

A: Yes. The Intel Core i5-14600T comes with UHD Graphics 770, while the Intel Core i5-14400 is equipped with UHD Graphics 730. This indicates a difference in the integrated GPU capabilities.

Q: What is the overall score difference in the database?

A: The Intel Core i5-14600T has an average benchmark score of 32707, placing it in the 83rd percentile of all CPUs. The Intel Core i5-14400 has an average score of 32115, placing it in the 82nd percentile. The 14600T leads by a margin of about 1.8% in average score.

The Verdict

The data points to the Intel Core i5-14600T as the superior processor for most tasks. It wins 17 out of 19 head-to-head benchmark comparisons, including all Cinebench and Geekbench tests. Its performance leadership is particularly pronounced in multi-core and single-core synthetic loads, where it often leads by large margins, such as a 34.3% advantage in Geekbench single-core and a 30.9% lead in Geekbench multi-core. This makes it the clear choice for users who prioritize raw CPU performance in applications like video editing, 3D rendering, and software compilation.

The Intel Core i5-14400, while losing most comparisons, is not without merit. It shows a lead in two specific Passmark tests: data compression and extended instructions. For workloads that rely heavily on those specific instruction sets, the 14400 could be the more suitable option. However, these wins are narrow in the case of data compression (4.2%) and more substantial in extended instructions (14.3%). Given its higher TDP of 65 watts, the 14400 might be intended for systems with more robust cooling solutions, but the benchmark data does not show a performance benefit from that higher power envelope in most scenarios. The selection should be based on whether the user needs the broad, dominant performance of the 14600T or the specific strengths of the 14400 in those two niche workloads.

Head-to-Head Benchmarks

The most striking result in the database is the Geekbench performance gap. The Intel Core i5-14600T scores 2559 points in Geekbench single-core, which is 34.3% higher than the 14400's 1905 points. This is a massive difference for a single-threaded test and suggests a significant advantage in the 14600T's ability to boost to its 5.10 GHz maximum frequency. The multi-core Geekbench test shows a similar story, with the 14600T scoring 12840 versus 9807, a 30.9% advantage. This indicates that the combination of more cores and a higher boost clock provides a substantial uplift in this workload.

Across the Cinebench suite, the 14600T consistently leads by a much smaller but still clear margin of 5.3%. This is seen in both multicore and singlecore tests for Cinebench R15, R20, and R23. For example, in Cinebench R23 multicore, the 14600T scores 22447 against 21315 for the 14400. This consistent 5.3% delta across all Cinebench versions suggests a stable performance advantage in this rendering engine, likely due to the higher core count and boost clock.

In the Passmark suite, the 14600T wins most tests, but the margins vary. The largest win for the 14600T is in the find_prime_numbers test, where it scores 121 versus 80, a 51.3% lead. It also shows strong wins in physics (34.2%) and integer math (16%). However, the 14400 fights back in two areas. In data compression, the 14400 scores 314995, which is 4.2% higher than the 14600T's 301827. More notably, in extended instructions, the 14400 scores 19816, a 14.3% advantage over the 14600T's 16985. These two wins are the only ones for the 14400, but they are significant enough to warrant attention for specific use cases.

Specification Differences

The two processors differ in several core specifications. The Intel Core i5-14600T features 14 cores and 20 threads, while the Intel Core i5-14400 has 10 cores and 16 threads. The base clock speeds are different, with the 14400 starting at 2.50 GHz and the 14600T at 1.80 GHz. Conversely, the boost clock is higher on the 14600T at 5.10 GHz, versus 4.70 GHz on the 14400. The TDP is a major differentiator, with the 14600T rated at 35 watts and the 14400 at 65 watts. The L2 cache is 2 MB per core on the 14600T and 1.25 MB per core on the 14400, and the L3 cache is 24 MB shared on the 14600T versus 20 MB shared on the 14400. The integrated graphics also differ, with the 14600T using UHD Graphics 770 and the 14400 using UHD Graphics 730. The launch MSRP for the 14600T is $255, and for the 14400 it is $221.

Architecture Differences

Both processors share the same Raptor Lake architecture and the Raptor Lake-R codename, and both are fabricated on Intel's 10 nm process node. The die size differs, with the 14600T measuring 257 mm² and the 14400 measuring 215 mm². This larger die size on the 14600T is consistent with its higher core count and larger cache. Both support DDR4 and DDR5 memory in a dual-channel configuration, and both support ECC memory. They also share the same PCIe Gen 5 interface with 16 lanes. The key architectural difference is the core and cache configuration, which is dictated by the different die sizes. The 14600T's larger L2 and L3 caches, combined with more cores, are the primary reasons for its performance advantage in most benchmarks. The 14400's smaller die and lower core count are offset by a higher base clock, but the data shows this does not translate into a general performance lead.

Where Each One Wins

The Intel Core i5-14600T is the winner in almost every scenario that the database measures. It dominates in all Cinebench tests, both Geekbench tests, and the majority of Passmark tests, including physics, integer math, floating point math, multithread, random string sorting, data encryption, and prime number finding. This makes it the obvious choice for users whose workloads rely on general-purpose computing, multi-threaded rendering, and high single-thread performance. Its 5.3% lead in Cinebench and 30.9% lead in Geekbench multi-core show it is well-suited for demanding applications like 3D modeling, video rendering, and scientific computation. The 34.2% lead in Passmark physics also suggests an advantage in simulation and physics-based workloads.

The Intel Core i5-14400 has a narrow but real niche. Its 4.2% win in Passmark data compression indicates it might be slightly better in file archiving or compression tasks. Its more substantial 14.3% win in Passmark extended instructions is more telling. This test measures performance on specialized instruction sets, such as those used in cryptography or certain multimedia codecs. For software that heavily utilizes these specific instructions, the 14400 could provide a tangible benefit. However, these are isolated wins. The data strongly suggests that for a general-purpose desktop processor, the 14600T is the superior part, while the 14400 is for users with a very specific workload that favors its unique instruction handling capabilities.
