Intel Core i7-14700HX vs Intel Core Ultra 5 225T Comparison

Head-to-Head Benchmarks

The Intel Core i7-14700HX dominates the head-to-head comparison, winning 12 of the 17 benchmark tests recorded in the database. The Intel Core Ultra 5 225T takes 5 wins, but the margin of victory in those tests is generally smaller than the deficits it suffers elsewhere.

The largest single gap appears in PassMark integer math, where the i7-14700HX scores 131296 against 59543 for the Ultra 5 225T, a delta of 120.5%. This is the most decisive result in the entire comparison. Data compression follows closely, with the i7-14700HX at 438539 versus 233998, a 87.4% advantage. Random string sorting shows a 68.7% lead for the i7-14700HX (48544 vs 28774).

In Cinebench multi-core tests, the i7-14700HX leads by varying margins. The R15 multicore score is 3812 against 2214, a 72.2% difference. R20 multicore shows 13059 versus 9227, a 41.5% gap. The R23 multicore gap narrows to 11.9%, with scores of 24595 and 21971. The R20 single-core test also favors the i7-14700HX, 1843 to 1302, a 41.6% delta, which is notable given the Ultra 5 wins other single-core tests.

PassMark multithread confirms the pattern: 36566 for the i7-14700HX versus 25358, a 44.2% lead. Data encryption shows a 42.7% advantage (26092 vs 18289), extended instructions a 28.1% lead (25718 vs 20083), and floating-point math a 13.4% edge (93836 vs 82751). The smallest multi-core win is PassMark physics, 2252 to 2053, a 9.7% difference.

The Ultra 5 225T wins Cinebench R23 single-core decisively: 3101 against 2103, a 32.2% margin. It also takes Cinebench R15 single-core, 312 to 296, a 5.1% edge. PassMark single-thread favors the Ultra 5 at 4348 versus 3947, a 9.2% lead. The most striking single-core win for the Ultra 5 is PassMark find prime numbers: 284 versus 165, a 41.9% margin, indicating a strong advantage in that specific workload.

The average benchmark score tells the overall story: the i7-14700HX records 45953, while the Ultra 5 225T sits at 30468. The i7-14700HX ranks in the 89th percentile of all CPUs in the database, while the Ultra 5 225T sits in the 82nd percentile.

Where Each One Wins

The i7-14700HX is the clear winner for heavily threaded workloads. Its 20 cores and 28 threads provide substantial throughput advantages in integer math, data compression, random string sorting, and multithreaded Cinebench runs. The 120.5% lead in integer math and 87.4% lead in data compression indicate that this processor is well suited for compute-heavy tasks that scale across many cores, such as code compilation, video rendering, or scientific computing. The 44.2% multithread advantage reinforces this profile.

The Ultra 5 225T wins in single-core performance, particularly in Cinebench R23 single-core where it leads by 32.2%, and in prime number finding where it leads by 41.9%. The single-thread PassMark score of 4348 versus 3947 shows a 9.2% advantage, suggesting that lightly threaded applications, such as spreadsheet work, web browsing, or older games that rely on one or two threads, would see better responsiveness from the Ultra 5. The R15 single-core win is narrow at 5.1%, but the R23 result shows that the Ultra 5's architectural efficiency becomes more apparent in newer, more demanding single-core tests.

The split is clear: the i7-14700HX is the throughput champion, while the Ultra 5 225T offers better per-core efficiency in specific workloads. The R20 single-core result is an outlier, with the i7-14700HX winning by 41.6%, which suggests that the Ultra 5's single-core advantage is not uniform across all test versions.

Architecture Differences

The two processors come from different Intel architectures and are built on different process nodes. The i7-14700HX uses Raptor Lake-HX, a 10 nm Intel process, while the Ultra 5 225T uses Arrow Lake-S, a 3 nm node from TSMC. The Ultra 5 225T integrates 17,800 million transistors on a 243 mm² die, while the i7-14700HX has no transistor count listed but uses a 257 mm² die.

Core counts differ substantially: the i7-14700HX has 20 cores and 28 threads, while the Ultra 5 225T has 10 cores and 10 threads, meaning no Hyper-Threading support on the latter. Cache hierarchies also differ. The i7-14700HX has 80 KB L1 per core, 2 MB L2 per core, and 33 MB shared L3. The Ultra 5 225T has 192 KB L1 per core, 3 MB L2 per core, and 20 MB shared L3. The larger per-core L1 and L2 on the Ultra 5 likely contribute to its single-core efficiency, while the larger shared L3 on the i7-14700HX benefits multi-core workloads.

Clock speeds differ as well. The i7-14700HX has a base clock of 2.10 GHz and a boost clock of 5.50 GHz. The Ultra 5 225T has a base of 2.50 GHz and a boost of 4.90 GHz. The i7-14700HX has a higher boost ceiling, while the Ultra 5 starts at a higher base.

Memory support differs: the i7-14700HX supports DDR4 and DDR5, while the Ultra 5 225T supports DDR5 only. The Ultra 5 has a listed memory bandwidth of 102.4 GB/s, while the i7-14700HX has no bandwidth figure recorded. The i7-14700HX supports ECC memory, while the Ultra 5 225T does not.

PCIe lanes differ: the i7-14700HX provides Gen 5 with 16 lanes (CPU only), while the Ultra 5 225T provides Gen 5 with 20 lanes (CPU only). The Ultra 5 thus offers more PCIe lanes for expansion.

Integrated graphics differ. The i7-14700HX uses UHD Graphics 770, while the Ultra 5 225T uses Arc Xe-LPG Graphics 16EU. The market segments also differ: the i7-14700HX is a mobile processor on Intel BGA 1964, while the Ultra 5 225T is a desktop processor on Intel Socket 1851. The i7-14700HX has an unlocked multiplier, while the Ultra 5 225T does not.

The i7-14700HX was released on 2024-01-07, while the Ultra 5 225T appeared on 2024-12-31. Both are listed as active production parts.

The Verdict

The benchmark data clearly separates these two processors by workload type. The Intel Core i7-14700HX is the stronger choice for multi-threaded, throughput-intensive tasks. It wins 12 of 17 head-to-head tests, with particularly large margins in integer math, data compression, and random string sorting. Its 20 cores, 28 threads, and 33 MB L3 cache deliver a 44.2% advantage in PassMark multithread and a 41.5% lead in Cinebench R20 multicore. The 89th percentile ranking versus 82nd for the Ultra 5 225T confirms its overall advantage in the database's CPU hierarchy.

The Intel Core Ultra 5 225T is the better option for single-core-bound workloads. Its 3 nm TSMC process, larger per-core caches, and higher base clock produce a 32.2% win in Cinebench R23 single-core and a 41.9% win in PassMark prime number finding. The PassMark single-thread score of 4348 versus 3947 shows a 9.2% edge. Its 10 cores and 10 threads are sufficient for lightly threaded applications, but the 10-core count limits its multi-core ceiling.

For users running heavily parallel workloads, the i7-14700HX is the clear pick from the recorded data. For users prioritizing single-thread responsiveness, the Ultra 5 225T holds the advantage. The i7-14700HX also offers ECC memory support and an unlocked multiplier, while the Ultra 5 225T provides more PCIe lanes and higher memory bandwidth. The choice depends entirely on whether the workload scales across cores or relies on per-core performance.
