AMD Ryzen AI 7 450G vs Intel Core 9 273PTE Comparison

Where Each One Wins

The benchmark data splits these two processors into very distinct roles. The AMD Ryzen AI 7 450G takes 9 of the 11 head-to-head comparisons, while the Intel Core 9 273PTE manages only 2 wins. That margin alone suggests the AMD part is the stronger all-around performer, but the specific workloads where Intel wins reveal a more nuanced picture.

The AMD Ryzen AI 7 450G dominates the data-heavy workloads. Its biggest victory comes in extended instructions, where it scores 28223 against Intel's 15952, a 76.9% advantage. Data compression shows a 55.7% lead with a score of 402831 versus 258704. Random string sorting goes to AMD by 47.3%, scoring 42663 against 28973. These are heavily parallel, compute-intensive tasks that leverage the AMD chip's architecture efficiently.

The Intel Core 9 273PTE wins in two specific areas: prime number finding and physics. Intel scores 142 in the find prime numbers test compared to AMD's 87, a 38.7% margin. In physics, Intel posts 1917 against AMD's 1440, a 24.9% advantage. These results indicate that for certain single-threaded integer-heavy or physics-simulation tasks, the Intel architecture holds a measurable edge despite losing the broader benchmark war.

The multithreaded score reflects the overall trend. AMD posts 30422 against Intel's 24054, a 26.5% lead. Single-thread performance also favors AMD at 4309 versus 3433, a 25.5% difference. The average benchmark scores reinforce this: the AMD part sits at 63331 average with a 93rd percentile ranking among all CPUs, while Intel manages 31143 average with an 82nd percentile ranking. The AMD chip sits in the same performance class as the Intel Core Ultra 7 265HX, which trails by just 0.2%, and the AMD Ryzen AI Max PRO 390, which leads by 0.7%. The Intel Core 9 273PTE, by contrast, competes with the Intel Core i7-12700F and AMD Ryzen 9 8945HS, both within 0.2% of its average score.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen AI 7 450G uses the Gorgon Point codename from the Ryzen AI 400 generation, built on a 4 nm TSMC process. It packs 8 cores and 16 threads with a 2.00 GHz base clock and 5.10 GHz boost clock. The Intel Core 9 273PTE uses the Bartlett Lake codename from the Core 9 generation, built on Intel's 10 nm process. It offers more cores at 12 and 24 threads, but with a lower 1.40 GHz base clock and a higher 5.50 GHz boost clock.

Cache configuration differs substantially. Both parts allocate 80 KB of L1 per core, but AMD provides 1 MB of L2 per core while Intel provides 2 MB per core. The L3 cache tells a different story: AMD has 8 MB total, while Intel has 36 MB shared. That larger L3 pool likely helps Intel in the physics and prime number tests, where repeated access to working sets benefits from more cache.

The memory controllers are similar in bandwidth at 89.6 GB/s for both, and both support dual-channel configurations. AMD supports DDR5 and LPDDR5X, while Intel supports both DDR4 and DDR5. Both support ECC memory. The PCIe implementation differs: AMD uses Gen 4 with 12 lanes from the CPU, while Intel uses Gen 5 with 16 lanes. That gives Intel a potential bandwidth advantage for storage and expansion cards.

Integrated graphics also differ. AMD uses the Radeon 860M, while Intel uses UHD Graphics 730. The AMD part has an unlocked multiplier, whereas the Intel part is locked. The AMD chip uses the AMD Socket AM5, while Intel uses the Intel Socket 1700. The AMD part is rated at 65 W TDP versus Intel's 45 W TDP, which means Intel claims a lower thermal envelope despite having more cores.

The production status for both is Active. AMD released on 2026-02-28, Intel on 2026-03-08. The Intel part has a launch MSRP of $549. The AMD part's launch MSRP is not recorded in the database.

The Verdict

The data points to the AMD Ryzen AI 7 450G as the stronger processor for most workloads. It wins 9 of 11 head-to-head benchmarks and holds a 63331 average score against Intel's 31143. The 93rd percentile ranking versus Intel's 82nd percentile confirms that AMD sits in a higher overall performance tier. The AMD part also delivers a 26.5% lead in multithreaded work and a 25.5% lead in single-threaded work, which covers the majority of general computing tasks.

The Intel Core 9 273PTE still has specific strengths. Its 38.7% win in prime number finding and 24.9% win in physics indicate that certain workloads, particularly those with heavy integer loops or physics simulation patterns, perform better on the Intel architecture. The larger 36 MB L3 cache and 2 MB per-core L2 likely contribute to these results. The higher 5.50 GHz boost clock also helps in bursty single-thread scenarios.

For users running data compression, encryption, extended instruction workloads, floating point math, integer math, or random string sorting, the AMD part is clearly the better choice based on the recorded measurements. For users whose primary workloads resemble prime number searching or physics calculations, the Intel part holds the advantage. The Intel part also carries a lower TDP of 45 W versus 65 W, which may matter in thermally constrained systems.
