Intel Core i5-14600T vs Intel Core Ultra 7 155H Comparison

The Intel Core i5-14600T and the Intel Core Ultra 7 155H are remarkably close in overall average benchmark score, with the desktop part scoring 32707 and the mobile part scoring 32697, a difference of exactly 0.0%. However, the distribution of those wins is heavily lopsided. The Core i5-14600T claims 16 of the 17 head-to-head benchmark victories, while the Core Ultra 7 155H secures only a single win. The i5-14600T dominates in single-threaded workloads, leading by as much as 81.8% in Cinebench R23 single-core, and also takes most multi-threaded tests despite having fewer cores and threads. The Ultra 7 155H’s lone victory comes in Cinebench R15 multi-core, where it leads by 7.7%. This is a classic case of a desktop-focused processor with higher boost clocks outperforming a more numerous but lower-clocked mobile chip in nearly every measurable workload.

The Verdict

From the data, the Intel Core i5-14600T is the clear performance choice for anyone building a desktop system. Its wins are not marginal; it leads by 49.4% in Cinebench R23 multi-core (22447 vs 15028) and by 81.8% in Cinebench R23 single-core (3169 vs 1743). The i5-14600T also holds advantages in every PassMark subtest except for the single Cinebench R15 multi-core result. For users prioritizing raw compute throughput, whether in integer math, floating-point math, or data compression, the i5-14600T is the superior option. Its 35 W TDP is higher than the Ultra 7’s 28 W, but the performance delta is substantial enough to justify that difference for desktop workloads.

The Intel Core Ultra 7 155H is a mobile processor, and its data reflects a different design goal. It has more cores (16 vs 14) and threads (22 vs 20) than the i5-14600T, yet it loses in most multi-threaded tests. Its single win in Cinebench R15 multi-core (2450 vs 2262) is its only highlight. For users constrained to a laptop or a compact mobile platform, the Ultra 7 155H is a capable processor in its own right, but the benchmark results show it is consistently behind the i5-14600T. The choice is straightforward: for a desktop build, the i5-14600T is the winner; for a mobile system, the Ultra 7 155H is the only option of the two, and it sacrifices significant performance compared to its desktop sibling.

Architecture Differences

The two processors come from different Intel generations and are built for different sockets. The i5-14600T is a Raptor Lake Refresh part on the Intel Socket 1700, while the Ultra 7 155H is a Meteor Lake part on the Intel BGA 2049 mobile socket. The process nodes differ: the i5-14600T uses a 10 nm node, while the Ultra 7 155H uses a 7 nm node. Despite this process advantage, the Ultra 7 does not translate it into higher scores in most tests.

Core configurations also differ. The i5-14600T features 14 cores and 20 threads, with a base clock of 1.80 GHz and a boost clock of 5.10 GHz. The Ultra 7 155H has 16 cores and 22 threads, with a higher base clock of 3.80 GHz but a lower boost clock of 4.80 GHz. The i5-14600T’s higher boost clock is likely a key factor in its single-threaded dominance. Cache hierarchies are similar in L2 and L3: both have 2 MB of L2 per core and 24 MB of shared L3. L1 cache differs slightly, with the i5-14600T offering 80 KB per core and the Ultra 7 offering 112 KB per core.

Memory support varies. The i5-14600T supports both DDR4 and DDR5 in a dual-channel configuration, and it supports ECC memory. The Ultra 7 155H supports DDR5 (depending on motherboard) in dual-channel, but does not support ECC. The Ultra 7 has a specified memory bandwidth of 89.6 GB/s, while the i5-14600T does not list a bandwidth figure. The i5-14600T offers more PCIe lanes (Gen 5, 16 lanes CPU only) compared to the Ultra 7’s Gen 5, 8 lanes CPU only. The integrated graphics differ as well: the i5-14600T uses UHD Graphics 770, while the Ultra 7 uses Arc Xe-LPG 128EU. The i5-14600T has a launch MSRP of $255, and the Ultra 7 has a launch MSRP of $503.

Head-to-Head Benchmarks

The head-to-head data reveals a stark pattern. The i5-14600T wins 16 benchmarks, with its largest margins in Cinebench R23 single-core (81.8% delta) and Cinebench R23 multi-core (49.4% delta). In Cinebench R20, the i5-14600T leads by 7.7% in both single-core (1330 vs 1235) and multi-core (9427 vs 8754). The same 7.7% margin appears in Cinebench R15 single-core, where the i5-14600T scores 319 versus the Ultra 7’s 255. The data shows consistent, robust advantages for the i5-14600T in the Cinebench suite.

In PassMark tests, the i5-14600T leads in every category. Data compression shows an 8.8% lead (301827 vs 277353). Data encryption is 11.4% ahead (18226 vs 16358). Extended instructions show a smaller 3.2% edge (16985 vs 16456). The floating-point math test is close, with the i5-14600T ahead by 1.6% (64726 vs 63703). Integer math is a 9.5% lead (95112 vs 86870). The multithread test shows a 6.2% advantage (26409 vs 24873). Physics, random string sorting, and single-thread tests round out the list with margins of 8.5%, 7.3%, and 8.0% respectively, all in favor of the i5-14600T.

The sole win for the Ultra 7 155H is in Cinebench R15 multi-core, where it scores 2450 against the i5-14600T’s 2262, a 7.7% delta. This single result does not offset the broader trend. The overall average benchmark scores are nearly identical (32707 vs 32697), but that average masks the fact that the i5-14600T wins in almost every individual metric, often by double-digit percentages.

Where Each One Wins

The Intel Core i5-14600T wins in nearly every scenario. For single-threaded applications, it is the definitive choice, with a 25.1% lead in Cinebench R15 single-core and an 81.8% lead in Cinebench R23 single-core. This translates to faster response times in tasks that rely on a single core, such as many legacy applications or lightly threaded games. For multi-threaded workloads, the i5-14600T also wins in Cinebench R20, R23, and all PassMark multi-threaded tests, including integer math (9.5% lead) and data compression (8.8% lead). The only exception is Cinebench R15 multi-core, where the Ultra 7 155H holds a 7.7% edge. If the workload is a mix of integer and floating-point operations, the i5-14600T leads in both, with margins of 9.5% and 1.6%, respectively.

The Intel Core Ultra 7 155H wins in one specific scenario: Cinebench R15 multi-core. This suggests a narrow niche where its higher core count and base clock are beneficial, but the data does not show this advantage extending to any other test. In all other benchmarks, the i5-14600T’s higher boost clock and desktop-oriented design prove superior. For users in a mobile form factor, the Ultra 7 155H is the only choice, but the benchmark data shows it is consistently slower than the i5-14600T. The i5-14600T is the clear winner for desktop users seeking maximum performance in both single-threaded and multi-threaded applications, with its 16 wins out of 17 head-to-head benchmarks making it the dominant part in this comparison.
