AMD Ryzen 9 PRO 8945HS vs Intel Core 9 273PQE Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive sweep: the Intel Core 9 273PQE wins all 17 head-to-head benchmark comparisons against the AMD Ryzen 9 PRO 8945HS. The margins are substantial, though they vary considerably by workload. The closest race appears in single-thread performance, where Intel leads by 14.3% in both PassMark single-thread tests, scoring 4573 against AMD's 3920. That gap widens to 35.9% in Cinebench R15 single-core, where Intel posts 557 versus AMD's 357.

Multi-threaded workloads show a consistent pattern. In Cinebench R23 multi-core, Intel scores 39190, which is 35.8% ahead of AMD's 25165. The same 35.8% delta appears across R15, R20, and R23 multi-core tests, suggesting a stable performance ceiling difference between the two. PassMark multithread shows Intel at 46107 versus AMD's 30378, a 34.1% advantage.

The most lopsided results appear in specialized compute tasks. PassMark find prime numbers gives Intel 198 against AMD's 91, a 54% deficit for the AMD part. Floating-point math shows a 49.4% gap, with Intel at 125546 and AMD at 63490. Physics simulation is close behind at 48.1% difference, Intel scoring 2754 versus AMD's 1430. Integer math favors Intel by 37.2%, with scores of 164629 and 103390 respectively.

Memory-sensitive and compression workloads tell a slightly different story. Random string sorting shows the smallest multi-core gap at 16%, Intel scoring 53167 against AMD's 44668. Data compression favors Intel by 37%, with 585752 versus 368884. Data encryption is closer at 26.4%, Intel at 29636 versus AMD's 21820. Extended instructions show a 28.5% gap, Intel at 38743 against AMD's 27714.

The aggregate benchmark score confirms the overall picture. Intel's average benchmark score is 66099, while AMD's is 41963, a 57.5% difference. Intel sits in the 93rd percentile of all CPUs in the database, while AMD sits in the 88th percentile. Intel's nearest rivals include the AMD Ryzen 9 7950X3D at a 0.3% delta and the Intel Core Ultra 5 250K Plus at -1.1%, placing it in strong company. AMD's nearest rivals include the Intel Core i7-14700T at 0.1% and the AMD Ryzen 5 7400 at -0.2%, showing it clusters with mid-range desktop parts.

Architecture Differences

The two processors come from fundamentally different design philosophies. AMD uses Zen 4 architecture on a Hawk Point codename, built on a 4 nm process at TSMC. Intel uses Bartlett Lake, built on a 10 nm process at Intel's own foundry. The process node difference is significant, though the database records show Intel still achieves higher performance through other means.

Core counts differ sharply. AMD provides 8 cores and 16 threads, while Intel provides 12 cores and 24 threads. That 50% core advantage for Intel explains much of the multi-core performance gap, though not all of it. AMD's base clock is 4.00 GHz with a boost of 5.20 GHz, while Intel's base is 3.40 GHz with a boost of 5.90 GHz. Intel's lower base clock but higher boost suggests a more aggressive turbo strategy.

Cache hierarchies diverge substantially. AMD allocates 64 KB L1 per core, 1 MB L2 per core, and 16 MB shared L3. Intel allocates 80 KB L1 per core, 2 MB L2 per core, and 36 MB shared L3. Intel's L3 cache is more than double AMD's, which likely contributes to the compression and encryption wins. The transistor count for AMD is recorded at 25,000 million on a 178 mm² die, while Intel's transistor count and die size are not recorded in the database.

Memory support differs in scope. AMD supports DDR5 only, while Intel supports both DDR4 and DDR5. Both use dual-channel memory buses with identical 89.6 GB/s bandwidth. Both support ECC memory. PCIe connectivity differs: AMD provides Gen 4 with 20 lanes, while Intel provides Gen 5 with 16 lanes. Intel's newer PCIe generation offers higher per-lane bandwidth, though fewer lanes.

Integrated graphics also differ. AMD uses Radeon 780M, while Intel uses UHD Graphics 770. The database does not record benchmark scores for either iGPU, so no performance comparison is possible. Market segments differ as well: AMD is a mobile part on AMD Socket FP7, while Intel is a desktop part on Intel Socket 1700. This explains the TDP difference: AMD runs at 45 W, Intel at 125 W. The power envelope difference is substantial and likely contributes to Intel's performance lead.

Release timing shows a significant gap. AMD launched on 2024-04-15, while Intel launched on 2026-03-08. Intel's part number is SA4Q9, while AMD has two recorded part numbers: 100-000001314 (FP7r2) and 100-000001386 (FP7). Neither has an unlocked multiplier.

The table shows the two processors differ in nearly every structural category. The cache hierarchy difference is particularly notable: Intel's L2 is double per core, and its L3 is more than double total. The process node difference favors AMD at 4 nm versus 10 nm, yet Intel's performance lead indicates architectural and core-count advantages override the node disadvantage.

The Verdict

The data points to a clear performance hierarchy. The Intel Core 9 273PQE outperforms the AMD Ryzen 9 PRO 8945HS across every recorded workload, with margins that range from modest single-thread gains to dramatic compute-heavy leads. Intel's 12-core, 24-thread configuration with 36 MB L3 cache and 5.90 GHz boost clock delivers results that place it in the 93rd percentile, while AMD's 8-core, 16-thread Zen 4 mobile part sits in the 88th percentile.

The market segments explain the disparity. AMD's 45 W mobile design targets power-constrained laptops, while Intel's 125 W desktop design targets performance-first desktops. The 80 W TDP difference is the most direct explanation for the performance gap, along with Intel's 50% core count advantage. The AMD part's efficiency story is evident: it achieves 88th percentile performance at 45 W, while Intel requires 125 W to reach the 93rd percentile.

The nearest rival data reinforces the positioning. Intel's closest competitors include the AMD Ryzen 9 7950X3D, a flagship desktop part, and the Intel Core Ultra 5 250K Plus. AMD's closest competitors include the Intel Core i7-14700T, a lower-power desktop chip, and the AMD Ryzen 5 7400. This shows the AMD mobile part competes with desktop mid-range chips, while the Intel desktop part competes with flagship-class silicon.

Where Each One Wins

The Intel Core 9 273PQE wins every recorded benchmark, but the magnitude of its wins varies by workload type. The largest advantages appear in mathematically intensive tasks: prime number finding (54% lead), floating-point math (49.4%), and physics (48.1%). These are compute-bound workloads that scale with cores and clock speed, where Intel's 12 cores and 5.90 GHz boost provide clear advantages. Data compression (37%) and integer math (37.2%) also strongly favor Intel, likely due to the larger L3 cache and higher core count.

The AMD Ryzen 9 PRO 8945HS shows relative strength in specific areas, even though it loses every test. Its smallest deficits appear in single-thread PassMark tests (14.3%) and random string sorting (16%). These workloads depend more on per-core efficiency than raw core count, and AMD's Zen 4 architecture on 4 nm TSMC process narrows Intel's lead. The data encryption gap (26.4%) and extended instructions gap (28.5%) are also smaller than the compute-heavy averages.

For power-constrained environments, the AMD part's 45 W TDP versus Intel's 125 W TDP suggests a meaningful efficiency difference, though the database records no direct power efficiency benchmark. The AMD processor is the only viable choice for thin-and-light mobile systems, while the Intel processor targets desktop builds where power delivery is less constrained. The Intel part's support for both DDR4 and DDR5 gives it broader memory compatibility, while AMD's DDR5-only support is a limiting factor for older memory ecosystems.

The release timeline also matters. AMD launched in April 2024, while Intel launched in March 2026. The Intel part's later release date means it benefits from additional architectural development time within the Bartlett Lake line. The launch MSRP of $589 for Intel provides a reference point, though the database records no launch MSRP for AMD.
