Intel Core i9-14900T vs Intel Core Ultra 5 225T Comparison

Head-to-Head Benchmarks

The benchmark data delivers a decisive verdict: the Intel Core i9-14900T wins 14 of the 17 head-to-head comparisons, with the Intel Core Ultra 5 225T taking only 3. The margin is not merely a matter of frequency; the i9-14900T leads by double-digit percentages in nearly every category, and in several workloads the gap is enormous.

The most striking result is in PassMark integer math. The i9-14900T scores 138149 against the Ultra 5 225T’s 59543, a 132% advantage. This is the largest single delta recorded between the two processors, and it reflects the i9-14900T’s substantially higher core count and thread count. Data compression tells a similar story: the i9-14900T scores 436066 versus 233998, a 86.4% lead. Random string sorting also favors the i9-14900T heavily, with a 72% edge (49484 versus 28774). These three workloads are heavily parallel, and the i9-14900T’s 24 cores and 32 threads overwhelm the Ultra 5 225T’s 10 cores and 10 threads.

Cinebench results reinforce the multi-core dominance. In Cinebench R23 multi-core, the i9-14900T scores 30803 against 21971, a 40.2% advantage. The same 40.2% delta appears in Cinebench R20 multi-core (12937 versus 9227) and Cinebench R15 multi-core (3104 versus 2214). Even in single-core Cinebench tests, the i9-14900T leads by 40.2%: 4348 versus 3101 in R23 single-core, 1826 versus 1302 in R20 single-core, and 438 versus 312 in R15 single-core. This is notable because the Ultra 5 225T has a higher base clock (2.50 GHz versus 1.10 GHz) and a newer process node, yet it still trails in single-threaded rendering workloads.

PassMark multi-thread confirms the pattern: 36239 for the i9-14900T versus 25358 for the Ultra 5 225T, a 42.9% lead. Data encryption shows a 48% advantage (27062 versus 18289). Floating-point math is closer but still favors the i9-14900T by 12% (92699 versus 82751). Extended instructions show a 17.8% edge (23660 versus 20083). Physics simulation is the narrowest i9-14900T win, at 9.4% (2245 versus 2053).

The Ultra 5 225T does claim three wins, and they are worth examining. PassMark find prime numbers favors the Ultra 5 225T by 42.3% (284 versus 164). This workload is sensitive to single-thread efficiency and clock speed, and the Ultra 5 225T’s higher boost clock of 4.90 GHz helps here. PassMark single-thread also goes to the Ultra 5 225T, with a score of 4348 versus 4016, a 7.6% lead. This is the same test recorded twice in the database under slightly different names (passmark_single_thread and passmark_singlethread), and both yield identical results.

Architecture Differences

The two processors come from completely different design generations. The i9-14900T is based on Raptor Lake, specifically Raptor Lake-R, and belongs to the Core 14th Gen series. It uses Intel’s 10 nm process node and is built on a 257 mm² die. The Ultra 5 225T is an Arrow Lake-S part from the Core Ultra Series 2, fabricated by TSMC on a 3 nm node with a 243 mm² die and 17,800 million transistors. The i9-14900T’s transistor count is not recorded in the database.

Core topology diverges sharply. The i9-14900T has 24 cores and 32 threads, indicating a hybrid arrangement of performance and efficiency cores. The Ultra 5 225T has 10 cores and 10 threads, meaning no hyper-threading support. Cache configurations also differ: the i9-14900T has 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3. The Ultra 5 225T has 192 KB of L1 per core, 3 MB of L2 per core, and only 20 MB of shared L3. Despite having less total L3, the Ultra 5 225T’s per-core L1 and L2 are larger, which helps in latency-sensitive single-threaded tasks.

Memory support is another dividing line. The i9-14900T supports both DDR4 and DDR5, while the Ultra 5 225T is DDR5-only. Both use dual-channel memory buses, but the Ultra 5 225T has a recorded memory bandwidth of 102.4 GB/s, while the i9-14900T’s bandwidth is not listed. ECC memory is supported on the i9-14900T but not on the Ultra 5 225T.

PCIe connectivity differs as well. The i9-14900T offers Gen 5 with 16 lanes (CPU only), while the Ultra 5 225T offers Gen 5 with 20 lanes (CPU only). Integrated graphics also change: the i9-14900T uses UHD Graphics 770, whereas the Ultra 5 225T uses Arc Xe-LPG Graphics 16EU. The i9-14900T uses an Intel Socket 1700, while the Ultra 5 225T uses Intel Socket 1851, meaning they are not interchangeable on the same motherboard.

Thermal design power is a major differentiator. The i9-14900T is rated at 35 W TDP, while the Ultra 5 225T is rated at 65 W. This is counterintuitive given the performance results: the i9-14900T delivers far higher multi-core throughput at half the TDP, though the Ultra 5 225T’s higher base clock (2.50 GHz versus 1.10 GHz) suggests a different power curve. The i9-14900T boosts to 5.50 GHz, while the Ultra 5 225T boosts to 4.90 GHz.

Where Each One Wins

The i9-14900T is the clear choice for heavily parallel workloads. Its 14 benchmark wins span rendering, compression, encryption, integer math, floating-point math, multi-threaded operations, and physics simulation. Data compression shows an 86.4% lead, integer math a 132% lead, and random string sorting a 72% lead. Users running Cinebench workloads, large data sets, or scientific computations will see substantial performance gains from the i9-14900T. The 40.2% advantage across all Cinebench tests, both single-core and multi-core, indicates that this processor is simply faster for rendering tasks of any scale.

The Ultra 5 225T wins in exactly one domain that matters for general responsiveness: single-threaded PassMark tests. Its 7.6% lead in passmark_single_thread (4348 versus 4016) and its 42.3% lead in find prime numbers (284 versus 164) suggest that for workloads that cannot use multiple cores and rely on raw single-thread speed, the Ultra 5 225T has an edge. The find prime numbers result is particularly notable because it shows a workload where the Ultra 5 225T more than doubles the i9-14900T’s score in percentage terms.

However, the i9-14900T also wins all three Cinebench single-core tests by 40.2%, which complicates the single-thread narrative. The PassMark single-thread test likely measures a different mix of instructions, where the Ultra 5 225T’s newer architecture and higher base clock pay off. But the Cinebench single-core results are unambiguous: the i9-14900T is faster there.

For users who prioritize multi-tasking, virtual machines, or content creation workflows that scale across cores, the i9-14900T is the stronger part. For users running legacy single-threaded applications, or workloads that specifically benefit from the Ultra 5 225T’s prime-number and single-thread PassMark strengths, the Ultra 5 225T may be sufficient, but its overall average benchmark score of 30468 versus the i9-14900T’s 51015 shows a 40.3% gap in aggregate performance.

The Verdict

The data is unambiguous. The Intel Core i9-14900T is the superior processor in aggregate performance, with an average benchmark score of 51015 versus 30468 for the Intel Core Ultra 5 225T. The i9-14900T wins 14 of 17 head-to-head tests, and its wins are often by massive margins: 132% in integer math, 86.4% in data compression, 72% in random string sorting, and 48% in data encryption. All Cinebench tests, both single-core and multi-core, show a consistent 40.2% advantage for the i9-14900T.

The Ultra 5 225T’s three wins are real but narrow in scope. Its 7.6% lead in PassMark single-thread and its 42.3% lead in find prime numbers indicate that certain single-threaded workloads prefer its higher base clock (2.50 GHz versus 1.10 GHz) and newer 3 nm process. However, the i9-14900T counters with a higher boost clock (5.50 GHz versus 4.90 GHz) and wins every Cinebench single-core test.

Architecturally, the Ultra 5 225T is a more modern design with TSMC’s 3 nm node, larger per-core L1 (192 KB versus 80 KB) and L2 (3 MB versus 2 MB) caches, and higher memory bandwidth (102.4 GB/s). Yet these advantages do not translate into benchmark victories outside the two PassMark tests. The i9-14900T’s 24 cores and 32 threads, combined with 36 MB of shared L3 cache, deliver a performance profile that the Ultra 5 225T cannot match in most scenarios.

The i9-14900T also carries a lower TDP of 35 W versus 65 W, meaning it achieves higher performance at a lower rated thermal envelope. It supports both DDR4 and DDR5 memory and ECC memory, offering more flexibility for workstation builds. The Ultra 5 225T is DDR5-only and lacks ECC support.

For users who need maximum multi-threaded throughput, the i9-14900T is the clear winner. Its benchmark data shows dominance in rendering, data processing, and math-heavy workloads. For users who prioritize specific single-threaded PassMark workloads, the Ultra 5 225T offers a modest edge, but the i9-14900T’s broader benchmark record makes it the recommended choice for virtually all compute-intensive tasks. The recorded data shows no scenario where the Ultra 5 225T’s advantages outweigh the i9-14900T’s comprehensive leads.
