Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 7 PRO 8840U uses the Zen 4 architecture under the Hawk Point codename, built on a 4 nm process at TSMC. It packs 25,000 million transistors into a 178 mm² die. The Intel Core 7 251TE uses the Bartlett Lake codename, built on a 10 nm process at Intel, with a die size of 215 mm². Intel does not list a transistor count in the database. The process node difference is substantial: 4 nm versus 10 nm, which explains how AMD fits a complete 8-core design into a smaller die.

Cache organization differs significantly. AMD uses a per-core split of 64 KB L1 and 1 MB L2, with 16 MB of shared L3. Intel uses 80 KB L1 per core and 1.25 MB L2 per core, with a much larger 36 MB shared L3. The Intel L3 cache is more than double AMD's, which helps in workloads that repeatedly access a large working set. AMD's smaller cache hierarchy reflects its mobile-first design, where power and die area are tighter constraints.

Memory support also diverges. AMD supports DDR5 only, on a dual-channel bus with 89.6 GB/s bandwidth. Intel supports both DDR4 and DDR5, also dual-channel, with the same 89.6 GB/s bandwidth figure. Both support ECC memory. PCIe connectivity differs: AMD provides Gen 4 with 20 lanes (CPU only), while Intel provides Gen 5 with 16 lanes (CPU only). The Gen 5 interface gives Intel the newer standard, though with fewer lanes.

The market segments place these chips in different worlds. AMD is a mobile processor on AMD Socket FP7, rated for 28 W TDP. Intel is a desktop processor on Intel Socket 1700, rated for 45 W TDP. The Intel chip is also newer in the database, with a release date of 2025-01-12 versus AMD's 2024-04-15. Production status for both is listed as Active. Neither processor has an unlocked multiplier.

Specification Differences

The specification table shows clear divergence in almost every field. Core count: 8 versus 24. Threads: 16 versus 32. Base clock: 3.30 GHz versus 1.40 GHz. Boost clock: 5.10 GHz versus 5.40 GHz. TDP: 28 W versus 45 W. Socket: AMD Socket FP7 versus Intel Socket 1700. Process node: 4 nm versus 10 nm. Foundry: TSMC versus Intel. Die size: 178 mm² versus 215 mm². Transistors: 25,000 million versus not listed.

Cache differs at every level. L1 per core: 64 KB versus 80 KB. L2 per core: 1 MB versus 1.25 MB. L3 shared: 16 MB versus 36 MB. Memory support: DDR5 only versus DDR4 and DDR5. PCIe: Gen 4 with 20 lanes versus Gen 5 with 16 lanes. Integrated graphics: Radeon 780M versus UHD Graphics 770. Market segment: Mobile versus Desktop. Release date: 2024-04-15 versus 2025-01-12. The Intel part has a listed launch MSRP of $384; AMD's launch MSRP is not recorded. Both support ECC memory and both use a dual-channel memory bus with 89.6 GB/s bandwidth.

The Intel chip's architecture field is listed as null in the database, while AMD's is explicitly Zen 4. Generation strings also differ: AMD is listed as Ryzen 7 (Zen 4 (Hawk Point)), Intel as Core 7 (Bartlett Lake). The part numbers are distinct: AMD lists 100-000001317(FP7r2) and 100-000001377(FP7), Intel lists SRQAXQ5ZG.

Where Each One Wins

The Intel Core 7 251TE dominates in every multi-core metric and most single-core metrics. Cinebench R23 multi-core at 25518 makes it the clear choice for rendering, video encoding, and compilation workloads. The PassMark multi-thread score of 30022 reinforces that. The physics test result, 1938 versus 1174, a 39.4% lead, points to simulation and physics-heavy tasks going to Intel. The floating point math advantage of 40.7% (85607 versus 50746) suggests scientific computing and numeric analysis favor Intel. Integer math, 125739 versus 88339, a 29.7% margin, favors Intel for general productivity and database-style workloads. Data compression at 334399 versus 272664 gives Intel an 18.5% edge in archiving and file-handling tasks. Encryption, 22176 versus 16441, a 25.9% lead, goes to Intel for security-related processing.

The AMD Ryzen 7 PRO 8840U wins exactly two distinct tests. PassMark extended instructions, 19132 versus 16974, a 12.7% margin, indicates AMD handles SIMD-style or specialized instruction workloads with better efficiency per clock. The PassMark single-thread result, 3641 versus 3568, a 2% edge, shows AMD has a slight advantage in lightly threaded, latency-sensitive tasks. The lower 28 W TDP also positions AMD favorably for thermally constrained environments, though the database does not include power efficiency benchmarks.

The 83rd percentile ranking for AMD versus the 88th for Intel puts the overall positioning into context. AMD's nearest rivals, the Core i9-11900 and Core i5-14400F, sit at nearly identical average scores (32226 and 32279 respectively), meaning the Ryzen 7 PRO 8840U slots into that performance tier. Intel's nearest rivals, the Core Ultra 7 265H and Core i7-14650HX, cluster around 41621 and 41576, a full performance tier higher.

The Verdict

The Intel Core 7 251TE is the faster processor in nearly every recorded benchmark. It wins 14 of 17 head-to-head comparisons, and the margins are often large. The 20.6% lead across all three Cinebench multi-core tests is consistent and meaningful. The 40.7% floating point advantage and 45.7% prime-number finding lead show that the gap grows with workload intensity. The 24-core, 32-thread configuration, 36 MB L3 cache, and 5.40 GHz boost clock give it a structural advantage that the benchmark data confirms. Its desktop segment, 45 W TDP, and Gen 5 PCIe support make it the choice for multi-threaded desktop workloads where raw throughput matters.

The AMD Ryzen 7 PRO 8840U is not without merit. It wins the extended instructions test by 12.7%, which indicates strength in specialized instruction workloads. Its 2% single-thread PassMark win, while small, shows it can hold its own in lightly threaded scenarios. The 28 W TDP and mobile segment designation make it suitable for compact or power-sensitive systems, and the 4 nm TSMC process gives it a transistor density advantage (25,000 million transistors on a 178 mm² die versus Intel's 215 mm² die). The 89.6 GB/s memory bandwidth matches Intel exactly, and both support ECC memory.

The data does not support a recommendation for AMD in performance-first scenarios. The average benchmark score difference, 41650 versus 32233, is a 29.2% gap in Intel's favor. The percentile ranking, 88th versus 83rd, reflects that gap. For any workload dominated by multi-core throughput, the Intel Core 7 251TE is the clear choice. For workloads that rely heavily on extended instructions, or for systems where the lower 28 W TDP and mobile form factor are priorities, the AMD Ryzen 7 PRO 8840U offers a narrower but valid alternative. The choice comes down to whether the workload is throughput-bound or constrained by power and physical footprint. The benchmark record is unambiguous: Intel wins the performance comparison, and AMD wins the efficiency-focused niche.
