AMD Ryzen AI 7 445 vs Intel Core 9 273PTE Comparison

The recorded data presents a clear performance hierarchy between the AMD Ryzen AI 7 445 and the Intel Core 9 273PTE. The Intel part wins 13 of 15 head-to-head benchmark comparisons, with the AMD chip taking only two, both in the same PassMark single-thread test. The Intel Core 9 273PTE delivers a higher average benchmark score of 31143 compared to the AMD's 26936, and it holds a higher percentile ranking at 82 versus 79. The AMD Ryzen AI 7 445 does retain a single-thread advantage, but the Intel processor's lead in multi-core and compute-intensive workloads is substantial, often exceeding 30%.

The Verdict

The data indicates the Intel Core 9 273PTE is the dominant processor for multi-threaded and compute-heavy tasks. Its Cinebench R23 multi-core score of 20445 is 48.2% higher than the AMD Ryzen AI 7 445's 10590. This pattern repeats across PassMark workloads: integer math shows a 29.2% lead (82411 vs 58332), floating point math shows a 35.1% lead (60673 vs 39362), and physics processing shows a 49.1% lead (1917 vs 976). For users running video encoding, 3D rendering, scientific simulations, or any workload that scales with core count and threads, the Intel Core 9 273PTE is the clear choice based on benchmark results.

The AMD Ryzen AI 7 445 claims a specific victory in single-threaded PassMark performance. It scores 3591 in the PassMark single-thread test, which is 4.6% higher than the Intel's 3433. This suggests the AMD part may offer snappier response in lightly threaded applications, such as general desktop navigation or single-threaded legacy software. However, this is a narrow win. In Cinebench R23 single-core, the Intel part leads by 37.4% (2886 vs 1806), and in Cinebench R15 single-core it leads by 12.4% (290 vs 254), showing that the AMD's single-thread advantage is not consistent across all test suites.

The Intel Core 9 273PTE also excels in memory-related and data tasks. It leads in PassMark data compression by 16.6% (258704 vs 215812) and data encryption by 26.2% (14253 vs 10519). The Intel part's 12 cores and 24 threads, versus the AMD's 6 cores and 12 threads, provide a structural advantage in parallel workloads. The AMD Ryzen AI 7 445 is a mobile processor with a 28 W TDP, making it suitable for thin-and-light laptops where battery life and thermal limits are priorities. The Intel Core 9 273PTE, a desktop processor with a 45 W TDP, is built for sustained performance in a desktop chassis. The selection depends on whether the priority is maximum throughput or power-efficient mobile operation.

Architecture Differences

The fundamental architectural split is significant. The AMD Ryzen AI 7 445 uses the Zen 5 architecture, codenamed Gorgon Point, manufactured on a 4 nm process by TSMC. The Intel Core 9 273PTE uses the Bartlett Lake codename, manufactured on a 10 nm process by Intel. These process nodes show a sizeable manufacturing difference, with the AMD part on a smaller 4 nm node versus Intel's 10 nm.

Core configuration differs sharply. The AMD Ryzen AI 7 445 has 6 cores and 12 threads, while the Intel Core 9 273PTE has 12 cores and 24 threads. This doubling of cores and threads directly explains the Intel part's multi-core benchmark dominance. Clock speeds also vary: the AMD part has a base clock of 2.00 GHz and a boost clock of 4.60 GHz, whereas the Intel part has a lower base clock of 1.40 GHz but a much higher boost clock of 5.50 GHz. The higher boost clock likely contributes to the Intel's strong single-core Cinebench results.

Cache hierarchy diverges as well. Both processors have 80 KB of L1 cache per core. The L2 cache differs, with the AMD at 1 MB per core and the Intel at 2 MB per core. The L3 cache shows a major difference: the AMD Ryzen AI 7 445 has 4 MB, while the Intel Core 9 273PTE has 36 MB shared. This larger L3 cache gives the Intel part a substantial buffer for frequently accessed data, which can improve performance in cache-sensitive workloads.

Platform support and connectivity also differ. The AMD Ryzen AI 7 445 uses AMD Socket FP8, supports DDR5 and LPDDR5X memory, and provides PCIe Gen 4 with 14 lanes. The Intel Core 9 273PTE uses Intel Socket 1700, supports DDR4 and DDR5 memory, and provides PCIe Gen 5 with 16 lanes. Both support ECC memory and dual-channel memory buses with 89.6 GB/s bandwidth. The Intel part's PCIe Gen 5 support offers newer connectivity options for desktop components. The AMD part features the Radeon 840M integrated graphics, while the Intel part uses UHD Graphics 730.

Head-to-Head Benchmarks

The Cinebench R23 multi-core test shows the most lopsided result. The Intel Core 9 273PTE scores 20445, beating the AMD Ryzen AI 7 445's 10590 by a margin of 48.2%. This is a near-doubling of performance and reflects the Intel's advantage in core count and thread count. The Cinebench R15 multi-core test shows a smaller but still clear Intel lead: 2060 versus 1723, a 16.4% advantage.

Single-core results are mixed across test suites. In Cinebench R23 single-core, the Intel wins with 2886 versus 1806, a 37.4% lead. In Cinebench R15 single-core, the Intel leads 290 versus 254, a 12.4% advantage. However, in the PassMark single-thread test, the AMD Ryzen AI 7 445 wins with 3591 versus 3433, a 4.6% lead. This inconsistency suggests the AMD's architectural efficiency shines in certain single-threaded workloads but not others.

PassMark compute tests consistently favor the Intel part. Integer math results show 82411 for the Intel versus 58332 for the AMD, a 29.2% lead. Floating point math shows 60673 versus 39362, a 35.1% lead. The find prime numbers test shows a 60.6% lead for the Intel (142 versus 56), which is the largest percentage gap in the PassMark suite. Physics processing shows a 49.1% lead (1917 versus 976). Extended instructions are nearly identical, with the Intel leading by only 0.8% (15952 versus 15826).

Data-oriented workloads also favor the Intel. Data compression scores are 258704 for the Intel versus 215812 for the AMD, a 16.6% lead. Data encryption scores are 14253 versus 10519, a 26.2% lead. Random string sorting shows 28973 versus 23488, an 18.9% lead. The PassMark multithread score is 24054 for the Intel versus 18115 for the AMD, a 24.7% lead.

Where Each One Wins

The Intel Core 9 273PTE wins in every multi-threaded and compute-heavy category. It dominates in Cinebench R23 and R15 multi-core tests, with leads of 48.2% and 16.4% respectively. In PassMark tests, it wins data compression, data encryption, extended instructions, find prime numbers, floating point math, integer math, multithread, physics, and random string sorting. The largest margins are in find prime numbers (60.6%), physics (49.1%), and Cinebench R23 multi-core (48.2%). These results indicate the Intel part is the stronger choice for rendering, scientific computing, video encoding, and any workload that can use 24 threads or a large 36 MB L3 cache.

The AMD Ryzen AI 7 445 wins in the PassMark single-thread test with a 4.6% margin. This is the sole benchmark category where it beats the Intel part. The AMD's higher base clock of 2.00 GHz and its Zen 5 architecture may contribute to this result, but the data only shows the final scores. This single-thread advantage could translate to faster response in applications that run on one or two threads, such as certain legacy software or basic office tasks. However, the Intel part's large single-core leads in both Cinebench R15 (12.4%) and R23 (37.4%) suggest that the AMD's single-thread win is not universal across all test methodologies.

The AMD Ryzen AI 7 445 also has the advantage of being a mobile processor with a 28 W TDP, versus the Intel's 45 W desktop TDP. The data shows the AMD uses less power, which is a meaningful consideration for laptop designs. The Intel part is a desktop processor with a higher TDP, but it delivers substantially higher performance in nearly every measured workload. The choice comes down to platform and power constraints versus raw throughput. The benchmark data consistently favors the Intel Core 9 273PTE for performance, while the AMD Ryzen AI 7 445 offers a specific single-thread win and a more power-efficient mobile package.
