AMD Ryzen 5 40 vs Intel Core 7 251TE Comparison

AMD Ryzen 5 40 vs Intel Core 7 251TE: the database comparison covers a mobile processor built on a 6 nm node against a desktop processor built on a 10 nm node. The Intel part wins every single recorded benchmark in the head-to-head set, a clean 15 to 0 sweep. The scale of the victory varies by workload, and the architectural gap explains most of it.

Head-to-Head Benchmarks

The Intel Core 7 251TE dominates the multi-core tests by a wide margin. In Cinebench R15 multi-core, the Intel part scores 2572 against the AMD's 790, a delta of -69.3%. The Cinebench R23 multi-core result is even more lopsided: 25518 versus 4841, a delta of -81%. The PassMark multi-thread score shows 30022 against 9341, a -68.9% gap. These results align with the core count difference, as the Intel part has 24 cores versus the AMD's 4 cores.

Single-core performance also favors the Intel part, though the gap is smaller. In Cinebench R15 single-core, Intel scores 362 against 165.5, a -54.3% delta. Cinebench R23 single-core shows 3602 versus 1150, a -68.1% delta. The PassMark single-thread test records 3568 against 2477, a -30.6% delta. The smaller single-thread gap suggests the AMD's Zen 2 architecture holds up reasonably well per clock, but the Intel part's higher boost clock of 5.40 GHz versus 4.30 GHz gives it the edge.

The encryption and math workloads show the largest deltas. PassMark data encryption: Intel 22176, AMD 6646, a -70% delta. PassMark floating point math: Intel 85607, AMD 15194, a -82.3% delta. PassMark integer math: Intel 125739, AMD 31598, a -74.9% delta. PassMark find prime numbers: Intel 140, AMD 20, a -85.7% delta. These workloads scale heavily with core count and memory bandwidth, both of which favor the Intel part.

The smallest recorded delta is in PassMark single-thread, at -30.6%. The largest is in PassMark find prime numbers, at -85.7%. The average benchmark score tells a similar story: the Intel part averages 41650, while the AMD averages 15882. The Intel part sits at the 88th percentile among all CPUs in the database, while the AMD sits at the 70th percentile.

Architecture Differences

The two processors come from different market segments and use different manufacturing approaches. The AMD Ryzen 5 40 is a mobile part on AMD Socket FT6, built on a 6 nm process by TSMC. It uses the Zen 2 architecture with the Mendocino codename. The Intel Core 7 251TE is a desktop part on Intel Socket 1700, built on a 10 nm process by Intel. It uses the Bartlett Lake codename.

The core counts differ substantially. The AMD has 4 cores and 8 threads. The Intel has 24 cores and 32 threads. This is a 6x difference in cores and a 4x difference in threads. The cache hierarchy also diverges. The AMD has 64 KB of L1 per core, 512 KB of L2 per core, and 4 MB of shared L3. The Intel has 80 KB of L1 per core, 1.25 MB of L2 per core, and 36 MB of shared L3. The Intel's L3 cache is 9x larger in total.

Memory support differs. The AMD supports LPDDR5 with dual-channel memory and 88.0 GB/s bandwidth. The Intel supports DDR4 and DDR5 with dual-channel memory and 89.6 GB/s bandwidth. The Intel also supports ECC memory, while the AMD does not. The PCIe interface differs: the AMD has Gen 3 with 4 lanes from the CPU, while the Intel has Gen 5 with 16 lanes from the CPU.

The integrated graphics differ as well. The AMD uses Radeon 610M, while the Intel uses UHD Graphics 770. The Intel's die size is 215 mm², while the AMD's is 100 mm². The Intel's base clock is 1.40 GHz with a boost clock of 5.40 GHz. The AMD's base clock is 2.80 GHz with a boost clock of 4.30 GHz. The Intel has a TDP of 45, while the AMD has a TDP of 15.

The release dates also differ. The AMD was released on 2025-09-30, while the Intel was released on 2025-01-12. The Intel has a launch MSRP of $384. The AMD has no recorded launch MSRP. The Intel has a part number of SRQAXQ5ZG, while the AMD's part number is unknown.

Where Each One Wins

The Intel Core 7 251TE wins every workload in the recorded benchmark set. The most decisive wins are in multi-threaded and math-heavy tasks. Cinebench R23 multi-core, PassMark floating point math, and PassMark find prime numbers all show deltas above -80%. These workloads benefit from the Intel's 24 cores, 32 threads, and 36 MB of L3 cache.

The AMD Ryzen 5 40 has no recorded benchmark wins. Its closest result is in PassMark single-thread, where the delta is -30.6%. This suggests the AMD's single-core performance per thread is competitive with the Intel part, but the Intel's higher boost clock still wins. The AMD's mobile segment does offer a lower TDP of 15, which indicates lower power draw, but the database does not record any performance-per-watt metrics.

For single-threaded workloads, the Intel part leads by roughly a third. For multi-threaded workloads, the Intel part leads by roughly two to five times. The Intel's advantage in encryption, integer math, and floating point math is consistent across all recorded tests. The AMD's only potential advantage lies in its smaller die size and lower TDP, which are not directly benchmarked.

The Verdict

The data shows a clear performance hierarchy. The Intel Core 7 251TE outperforms the AMD Ryzen 5 40 in every recorded benchmark, with average scores 2.6x higher. The Intel part belongs to the 88th percentile of all CPUs, while the AMD sits at the 70th percentile. The Intel's nearest rivals include the Intel Core Ultra 7 265H with a delta of 0.1%, the Intel Core i7-14650HX with a delta of 0.2%, and the Intel Core i7-14700T with a delta of -0.6%. The AMD's nearest rivals include the AMD EPYC 75F3 with a delta of 0.1%, the Intel Core Ultra 5 134U with a delta of -0.2%, and the AMD EPYC 9334 with a delta of -0.4%.

The database indicates that the Intel part is a desktop processor with 24 cores, 32 threads, and a 5.40 GHz boost clock. The AMD part is a mobile processor with 4 cores, 8 threads, and a 4.30 GHz boost clock. For any workload that benefits from multiple cores, the Intel part is the clear choice. For single-threaded tasks, the Intel part still leads, but the margin is smaller. The AMD part offers a lower TDP and a smaller die size, which may be relevant for mobile designs, but the benchmark data does not show any performance scenario where the AMD wins.

Users who need maximum multi-core throughput should select the Intel part. Users who prioritize the lowest power draw in a mobile form factor might consider the AMD, but the performance gap is substantial. The Intel part costs $384 at launch, which the database records as its launch MSRP.
