The Verdict

The data separates these two clearly by workload type. The Intel Core Ultra 5 245T is the stronger all-around compute part in most measured categories. It wins 11 of 15 head-to-head tests, including all single-thread tests, all Cinebench R23 runs, and major PassMark workloads like encryption, floating point math, prime number finding, physics, and multithread. For users running rendering, encryption, physics simulation, or any single-thread-sensitive application, the Intel part delivers the higher recorded scores.

The AMD Ryzen AI 7 450 has a narrower but distinct set of strengths. It wins data compression by 11.3%, extended instructions by 1.5%, random string sorting by 2.1%, and Cinebench R15 multi-core by 2.7%. Its average benchmark score is higher overall (39485 versus 38194), and it sits one percentile point higher in the database. This suggests that in mixed or balanced workloads, the AMD part can match or exceed the Intel chip despite losing most individual tests.

The choice depends on the dominant workload. For single-thread performance, multi-core rendering, and math-heavy tasks, the Intel Core Ultra 5 245T is the clear pick from the recorded data. For data compression, string sorting, and tasks that benefit from its higher average score, the AMD Ryzen AI 7 450 is the better selection. The Intel part's launch MSRP is $270, and it targets the desktop segment with a 65 W TDP, while the AMD part is a 28 W mobile chip.

Head-to-Head Benchmarks

The largest Intel win is in Cinebench R23 single-core, where the Core Ultra 5 245T scores 3699 against the Ryzen AI 7 450's 2038, a 44.9% margin. Cinebench R15 single-core shows a similar 42.2% gap (372 versus 215). These two results establish that the Intel architecture has a substantial per-thread advantage in the database's recorded Cinebench runs.

In floating point math, the Intel part scores 108499 versus 54447, a 49.8% lead. Prime number finding shows the largest relative gap of all: 324 versus 89, a 72.5% Intel advantage. Data encryption also favors Intel by 31.3% (23656 versus 16247). These math and encryption results indicate that the Intel chip handles computational density far better in these specific PassMark tests.

The AMD's biggest win is in data compression, scoring 315906 against Intel's 283812, an 11.3% lead. Random string sorting goes to AMD by 2.1% (35648 versus 34931). Extended instructions is a narrow AMD win at 22400 versus 22071, a 1.5% margin. Cinebench R15 multi-core also goes to AMD at 2713 versus 2641, a 2.7% edge.

The remaining tests are closer or favor Intel by smaller margins. PassMark integer math is essentially tied: Intel scores 88676, AMD scores 88531, a 0.2% difference. PassMark multithread favors Intel by 14.5% (30833 versus 26350). PassMark physics favors Intel by 30.7% (2278 versus 1578). Cinebench R23 multi-core favors Intel by 30.1% (26208 versus 18316).

The average benchmark scores confirm the mixed picture: AMD's 39485 average is 0.3% above its nearest rival, the Ryzen 7 PRO 8840HS, while Intel's 38194 average is 0.1% below the Ryzen 7 250. Both processors sit near their closest competitors in the database, but the AMD part has a slightly higher overall average.

Specification Differences

The core and thread counts differ significantly. The AMD Ryzen AI 7 450 uses 8 cores and 16 threads. The Intel Core Ultra 5 245T uses 14 cores and 14 threads. The Intel part has more physical cores but no hyperthreading, while the AMD part relies on simultaneous multithreading to double its thread count.

The process node differs: AMD uses TSMC's 4 nm process, while Intel uses TSMC's 3 nm process. The AMD die size is 195 mm², while the Intel die is 243 mm². The Intel part lists 17,800 million transistors; the AMD part does not have a recorded transistor count.

Cache configurations are different. The AMD has 80 KB L1 per core, 1 MB L2 per core, and 8 MB L3. The Intel has 192 KB L1 per core, 3 MB L2 per core, and 24 MB shared L3. The Intel L3 cache is three times larger in total.

Memory support differs. Both support DDR5 and dual-channel memory, but the AMD also supports LPDDR5X. The AMD memory bandwidth is 89.6 GB/s, while the Intel is 102.4 GB/s. Both support ECC memory.

PCIe generations and lane counts differ. The AMD uses PCIe Gen 4 with 16 CPU lanes. The Intel uses PCIe Gen 5 with 20 CPU lanes. The integrated graphics also differ: AMD includes Radeon 860M, while Intel includes Arc Xe-LPG Graphics 64EU.

The market segments are different. The AMD is a mobile processor with a 28 W TDP on AMD Socket FP8. The Intel is a desktop processor with a 65 W TDP on Intel Socket 1851. The release dates differ: the AMD launched on 2026-01-04, while the Intel launched on 2025-01-06. Neither processor has an unlocked multiplier.

Architecture Differences

The AMD Ryzen AI 7 450 uses the Zen 5 architecture under the codename Gorgon Point, part of the Ryzen AI 400 generation. The Intel Core Ultra 5 245T uses the Arrow Lake architecture under the codename Arrow Lake-S, part of the Ultra 5 generation.

The core designs diverge in approach. AMD's 8-core configuration with 16 threads relies on Zen 5 cores with simultaneous multithreading. Intel's 14-core, 14-thread configuration uses a mix of performance and efficiency cores typical of Arrow Lake, with no multithreading. The thread count parity (16 versus 14) masks the different core strategies.

The process nodes reflect different manufacturing points. AMD uses TSMC's 4 nm process, while Intel uses TSMC's 3 nm process. The smaller node for Intel does not translate into a smaller die: Intel's 243 mm² die is larger than AMD's 195 mm². The transistor count of 17,800 million for Intel suggests a denser implementation, but the AMD part has no recorded transistor figure.

Cache architecture is a major differentiator. Intel's 24 MB shared L3 dwarfs AMD's 8 MB L3. Intel also provides larger per-core L1 (192 KB versus 80 KB) and L2 (3 MB versus 1 MB). These larger caches likely contribute to Intel's single-thread and floating point advantages in the recorded benchmarks.

Memory bandwidth favors Intel at 102.4 GB/s versus AMD's 89.6 GB/s, a 14.3% advantage. The AMD supports LPDDR5X in addition to DDR5, which may matter for mobile power-sensitive designs, but the Intel's higher peak bandwidth is reflected in its memory-dependent benchmark results.

PCIe capabilities differ substantially. Intel provides PCIe Gen 5 with 20 lanes, while AMD provides PCIe Gen 4 with 16 lanes. For desktop expansion, the Intel part has both a newer generation and more lanes. The AMD's mobile socket limits its expansion context.

Where Each One Wins

The Intel Core Ultra 5 245T wins in single-thread performance across all recorded tests. Cinebench R15 single-core shows a 42.2% lead, Cinebench R23 single-core shows a 44.9% lead, and PassMark single-thread shows a 10.7% lead. Any workload that depends heavily on one core, such as legacy applications or lightly threaded productivity tools, favors the Intel part.

The Intel part also dominates in math-heavy and encryption workloads. Floating point math shows a 49.8% lead, prime number finding shows a 72.5% lead, and data encryption shows a 31.3% lead. Physics simulation favors Intel by 30.7%. These results point to scientific computing, financial modeling, and encryption-heavy server tasks as clear Intel territory.

Multi-core rendering favors Intel in Cinebench R23, where the 30.1% lead (26208 versus 18316) is substantial. PassMark multithread also favors Intel by 14.5%. The 14-core Intel design outperforms the 8-core AMD in sustained all-core rendering despite the AMD's thread count advantage.

The AMD Ryzen AI 7 450 wins in data compression by 11.3%, making it the better choice for file archiving, compression utilities, and database workloads that rely on compression throughput. Random string sorting favors AMD by 2.1%, suggesting an edge in sorting-heavy data processing tasks.

Extended instructions favor AMD by 1.5%, a narrow margin that indicates competitive performance in SIMD-heavy code. Cinebench R15 multi-core favors AMD by 2.7%, and while this is a smaller lead than Intel's R23 margin, it shows the AMD part can win in certain older multi-threaded workloads.

The AMD's higher average benchmark score (39485 versus 38194) and higher percentile rank (87 versus 86) indicate that in a balanced mix of workloads, the AMD part can edge ahead despite losing the majority of individual tests. For mobile users who need compression performance, sorting throughput, and a competitive average score at a 28 W TDP, the AMD Ryzen AI 7 450 is the data-supported choice. For desktop users prioritizing single-thread speed, rendering, math, encryption, and physics, the Intel Core Ultra 5 245T is the stronger pick.
