Intel Core 7 251TE vs Intel Core i5-14500T Comparison

Head-to-Head Benchmarks

The benchmark comparison between the Intel Core 7 251TE and the Intel Core i5-14500T is overwhelmingly one-sided. The Core 7 251TE wins 15 of the 17 recorded head-to-head tests, while the i5-14500T manages just 2 wins. The margin of victory is often substantial, pointing to a clear performance hierarchy.

The most dramatic difference appears in Cinebench R23 multi-core. Here the Core 7 251TE scores 25518 against 11790 for the i5-14500T, a delta of 116.4%. That is more than double the multi-threaded rendering output. The single-core R23 result tells a similar story, with 3602 versus 1838, a 96% advantage. This suggests the Core 7 251TE does not merely scale better with more cores; its individual core performance is also significantly stronger in this workload.

Cinebench R20 shows a narrower but still large gap. Multi-core scores are 10717 versus 8177, a 31.1% lead, while single-core is 1512 against 1154, a 31% lead. R15 repeats the pattern: 2572 versus 2022 in multi-core (27.2%) and 362 versus 252 in single-core (43.7%). The R15 single-core delta is particularly striking, indicating a major per-thread advantage in older rendering tests.

PassMark tests confirm the trend across varied workloads. Integer math shows 125739 versus 80922, a 55.4% lead. Floating point math delivers 85607 against 58869, a 45.4% gap. Physics simulation favors the Core 7 251TE by 50.5% (1938 versus 1288). Prime number finding is a 72.8% difference (140 versus 81). Data encryption is 43.9% faster (22176 versus 15410), and data compression is 27.4% ahead (334399 versus 262417). Random string sorting shows a 39.3% lead (39643 versus 28462). Even the extended instructions test, which shows the narrowest multi-core gap, still favors the Core 7 251TE by 5.8% (16974 versus 16043).

The only two tests won by the i5-14500T are PassMark single-thread and the identical PassMark singlethread result. Both show 3736 for the i5-14500T against 3568 for the Core 7 251TE, a 4.5% advantage. This is the one area where the older chip demonstrates a measurable edge, likely reflecting a higher single-thread frequency profile in that specific benchmark suite.

The overall average benchmark scores reinforce the picture. The Core 7 251TE averages 41650, placing it in the 88th percentile of all CPUs. The i5-14500T averages 28065, which is the 80th percentile. The nearest rival for the Core 7 251TE is the Intel Core Ultra 7 265H at 41621 (0.1% behind), while the i5-14500T sits alongside the AMD Ryzen 5 PRO 8500GE at 28054 (0% delta). These percentile positions place the two chips well apart in the overall performance distribution.

Architecture Differences

The two processors share a surprising number of physical characteristics. Both are built on a 10 nm process at Intel, both use the Intel Socket 1700, and both have the same 215 mm² die size. They also share the same L1 cache structure at 80 KB per core and the same L2 cache at 1.25 MB per core. The integrated graphics are identical as well: UHD Graphics 770 in both cases. PCIe support matches too, with Gen 5 and 16 lanes from the CPU.

The core configuration diverges sharply. The Core 7 251TE uses 24 cores and 32 threads, while the i5-14500T has 14 cores and 20 threads. This 10-core and 12-thread difference explains much of the multi-threaded performance gap. The Core 7 251TE belongs to the Bartlett Lake codename family, whereas the i5-14500T is based on Raptor Lake-R, part of the Raptor Lake Refresh generation. The Core 7 251TE is listed simply as Core 7 (Bartlett Lake) with no separate architecture field, while the i5-14500T explicitly carries the Raptor Lake architecture label.

Clock speeds tell a more nuanced story. The Core 7 251TE has a base clock of 1.40 GHz and a boost clock of 5.40 GHz. The i5-14500T has a higher base clock of 1.70 GHz but a lower boost of 4.80 GHz. The higher base clock on the i5-14500T may contribute to its single-thread PassMark win despite the lower boost ceiling, while the Core 7 251TE relies on a much higher top frequency for burst workloads.

L3 cache is another clear differentiator. The Core 7 251TE has 36 MB shared L3, while the i5-14500T has 24 MB shared. That is a 12 MB advantage for the Core 7 251TE, which can help with larger working sets in rendering and data-heavy tasks. Memory bandwidth is listed for the Core 7 251TE at 89.6 GB/s, while the i5-14500T has no recorded bandwidth figure. Both support DDR4 and DDR5 memory on a dual-channel bus, and both support ECC memory.

The TDP ratings differ meaningfully. The Core 7 251TE is rated at 45 W, while the i5-14500T is rated at 35 W. The Core 7 251TE delivers far higher performance within a 10 W higher envelope, which is a notable efficiency result given the doubling of multi-core Cinebench R23 output. The release dates are also distinct: the i5-14500T arrived on 2024-01-07, while the Core 7 251TE launched on 2025-01-12, roughly a year later. The launch MSRP for the Core 7 251TE is $384, and for the i5-14500T it is $232. Neither chip has an unlocked multiplier, and both are marked as Active in production status.

The Verdict

The data indicates a decisive performance hierarchy. The Core 7 251TE dominates the i5-14500T across every multi-threaded workload in the database and in most single-threaded tests as well. The Cinebench R23 multi-core delta of 116.4% is the single largest gap recorded between the two, and it aligns with the 24-core versus 14-core configuration difference. The Core 7 251TE also delivers a higher average benchmark score (41650 versus 28065) and a higher percentile rank (88 versus 80).

Users who prioritize multi-threaded rendering, physics simulation, encryption, compression, or integer and floating point math should select the Core 7 251TE based on these measurements. The i5-14500T retains a narrow 4.5% lead in PassMark single-thread performance, which makes it the better choice for workloads that are strictly dependent on that specific single-thread metric. The i5-14500T also operates at a lower 35 W TDP, which may matter for thermally constrained systems, though the Core 7 251TE offers vastly more performance at only 10 W higher.

The architectural differences support the benchmark results. More cores, more threads, more L3 cache, and a higher boost clock all favor the Core 7 251TE. The i5-14500T counters with a higher base clock and a lower TDP. The Core 7 251TE is the newer part by roughly a year, which may explain its superior per-core results in most tests despite the same process node and die size.

The choice is straightforward from the recorded data. For maximum throughput, the Core 7 251TE is the clear winner. For low-power single-thread tasks where the PassMark single-thread score is the deciding factor, the i5-14500T has a measurable, if limited, advantage.

Where Each One Wins

The Core 7 251TE wins in nearly every category measured. Multi-threaded rendering is its strongest domain, as shown by the 116.4% lead in Cinebench R23 multi-core and the 31.1% lead in Cinebench R20 multi-core. Physics simulation favors it by 50.5%, which indicates strong performance in physics-based workloads. Integer math (55.4% lead) and floating point math (45.4% lead) both fall firmly in its favor. Data encryption is 43.9% faster, and data compression is 27.4% faster. Prime number finding, a heavily integer-bound workload, shows a 72.8% advantage. Random string sorting is 39.3% faster. The extended instructions test, the closest multi-core result, still gives it a 5.8% lead.

The i5-14500T wins only in PassMark single-thread performance, with a 4.5% edge. This makes it suitable for legacy single-threaded applications or scenarios where the specific PassMark single-thread metric is the target. Its 35 W TDP also gives it a lower power envelope, which could be relevant in power-constrained builds.
