AMD Ryzen AI 7 450G vs Intel Core 7 251TE Comparison

Head-to-Head Benchmarks

The PassMark suite splits this matchup almost evenly, with AMD Ryzen AI 7 450G taking 6 of 11 recorded tests and Intel Core 7 251TE taking 5. The most decisive AMD victory comes in extended instructions, where the Ryzen AI 7 450G scores 28223 against 16974 for the Intel part, a 66.3% advantage. That margin is the largest in the entire comparison and suggests a substantial difference in SIMD or specialized workload execution.

Single-thread performance also favors AMD clearly. The Ryzen AI 7 450G posts 4309 in both passmark_single_thread and passmark_singlethread, while the Intel Core 7 251TE records 3568 in each. That translates to a 20.8% lead for AMD in single-threaded tasks, a meaningful gap for lightly threaded applications such as everyday desktop response or legacy software.

Data compression heavily favors AMD as well. The Ryzen AI 7 450G compresses at 402831 versus 334399 for Intel, a 20.5% difference. Random string sorting also goes AMD's direction, with 42663 against 39643, a 7.6% edge. The multithread PassMark score is nearly a tie, with AMD at 30422 and Intel at 30022, giving AMD a slim 1.3% win in that aggregate test.

Intel's wins are concentrated in number-crunching and physics workloads. Floating point math shows Intel at 85607 versus 63683 for AMD, a 25.6% advantage. Integer math follows with Intel at 125739 against 99732, a 20.7% lead. Physics simulation sees Intel score 1938 versus 1440 for AMD, a 25.7% gap. Prime number finding is Intel's most lopsided win: 140 versus 87, a 37.9% margin.

Data encryption is the only Intel win below 20%, with Intel at 22176 and AMD at 18937, a 14.6% difference. Overall, the pattern shows AMD dominating latency-sensitive, branch-heavy, and compression workloads while Intel overwhelms in raw arithmetic throughput and physics.

Where Each One Wins

The AMD Ryzen AI 7 450G clearly wins in single-threaded productivity, extended instruction workloads, compression, and sorting. For users running compression tools, string manipulation scripts, or any application that relies on single-core responsiveness, the data points to AMD. The 20.8% single-thread lead and 66.3% extended instruction advantage make it the stronger choice for lightly threaded desktop tasks and vectorized code that uses modern instruction sets.

The Intel Core 7 251TE wins in pure computational throughput. Floating point math, integer math, physics, and prime number calculations all go to Intel by margins from 20.7% to 37.9%. This indicates a clear advantage for scientific computing, simulation, encryption workloads, and any number-crunching that can spread across its higher core count. The encryption result, while smaller, still favors Intel and points to cryptography or hashing tasks as Intel-friendly territory.

The multithread PassMark score is effectively a wash at 1.3% apart, meaning neither chip has a meaningful aggregate multi-core advantage in that metric. However, Intel's individual math and physics wins suggest that specific multi-threaded workloads with heavy arithmetic will favor Intel, while AMD's multithread win, albeit tiny, comes from a mix of compression and sorting tasks where it excels.

Architecture Differences

The AMD Ryzen AI 7 450G uses the Gorgon Point codename from the Ryzen AI 400 generation, built on Zen 5 and Zen 5c cores. It is manufactured on a 4 nm process at TSMC with a die size of 195 mm². The chip packs 8 cores and 16 threads, with a base clock of 2.00 GHz and a boost clock of 5.10 GHz. Its thermal design power is 65 watts, and it uses the AMD Socket AM5. The multiplier is unlocked, allowing overclocking.

Intel's Core 7 251TE comes from the Bartlett Lake codename in the Core 7 generation. It is built on a 10 nm process at Intel's own foundry, with a larger die at 215 mm². This chip offers substantially more cores: 24 cores and 32 threads, with a base clock of 1.40 GHz and a boost clock of 5.40 GHz. Its thermal design power is lower at 45 watts, and it uses the Intel Socket 1700. The multiplier is locked, so overclocking is not available.

Cache configurations differ notably. Both chips have 80 KB of L1 cache per core. AMD provides 1 MB of L2 per core, while Intel provides 1.25 MB per core. The L3 cache is where Intel pulls ahead significantly: AMD has 8 MB total L3, while Intel has 36 MB shared L3. That difference helps explain Intel's strong showing in math-heavy workloads that benefit from large shared caches.

Memory support also diverges. AMD supports DDR5 and LPDDR5X, while Intel supports DDR4 and DDR5. Both use dual-channel memory with identical memory bandwidth of 89.6 GB/s. Both support ECC memory. PCIe capabilities favor Intel: the Intel chip offers Gen 5 with 16 lanes from the CPU, while AMD offers Gen 4 with 12 lanes from the CPU.

Integrated graphics differ as well. AMD uses the Radeon 860M, while Intel uses UHD Graphics 770. The AMD part is a desktop segment product with an active production status and a release date in February 2026. The Intel part is also desktop segment, active, with a release date in January 2025 and a launch MSRP of $384.

The Verdict

The benchmark data presents a clear split based on workload type. For users prioritizing single-threaded performance, compression, sorting, and modern extended instruction execution, the AMD Ryzen AI 7 450G is the stronger choice. Its 20.8% single-thread lead and 66.3% extended instruction margin are decisive, and its 20.5% compression advantage reinforces that position.

For users prioritizing raw arithmetic, physics simulation, and heavy floating-point or integer math, the Intel Core 7 251TE is the better selection. Its 25.6% floating-point lead, 20.7% integer lead, and 37.9% prime number advantage are hard to ignore. The larger 36 MB L3 cache and higher core count of 24 versus 8 give it structural advantages in these areas.

The multithread aggregate is nearly even, so the decision should rest on specific workload profiles rather than a general multi-core verdict. The AMD part also offers an unlocked multiplier and a smaller die on a more advanced 4 nm process, while Intel offers a lower 45 watt TDP, Gen 5 PCIe, and DDR4 compatibility for legacy memory. Neither chip dominates across all metrics, and the data supports choosing based on whether the primary tasks are single-thread-bound or arithmetic-heavy.
