AMD Ryzen Embedded 8840U vs Intel Core i9-14901TE Comparison

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark scores for the AMD Ryzen Embedded 8840U and the Intel Core i9-14901TE. Both processors have an empty benchmark array, an average benchmark score of zero, and zero recorded wins in direct comparison. The absence of measured performance data means no direct numerical comparison of compute throughput, memory latency, or power-normalized performance can be made from the database. Both parts sit at the 50th percentile against all CPUs in the database, a placeholder value that reflects the lack of recorded results rather than an actual performance tier.

Without benchmark scores, the only quantitative differentiators available are architectural and specification-level. The AMD part boosts to 5.10 GHz across its 8 cores, while the Intel part boosts to 5.50 GHz, a 0.40 GHz advantage for Intel at the top end. Base clocks differ more substantially: AMD runs at 3.30 GHz, Intel at 2.30 GHz, giving AMD a 1.00 GHz base-clock lead. These clock figures do not translate directly into performance without knowing sustained power limits, thermal behavior, and per-core scaling, but they do indicate different design targets. The Intel part is configured for a higher peak frequency at the expense of a much lower base frequency, suggesting a processor that relies on burst behavior, while the AMD part maintains a higher floor across all cores.

The thermal design point differs by 17 watts. Intel is rated at 45 W TDP, AMD at 28 W TDP. This 60.7% higher TDP on the Intel side implies a larger power envelope for sustained workloads, but without measured power consumption or benchmark scores, the efficiency relationship cannot be quantified. The database records no power efficiency metric, no performance-per-watt figure, and no thermal test results.

The memory bandwidth figures are not directly comparable because the Intel part has no recorded bandwidth value. AMD lists 89.6 GB/s for dual-channel DDR5. Intel supports both DDR4 and DDR5, but the database does not record a bandwidth number for that part. The absence of a bandwidth figure for Intel means any comparison of memory throughput is impossible from the recorded data.

Both processors share core and thread counts: 8 cores and 16 threads each. They also share ECC memory support, dual-channel memory bus configuration, and locked multipliers. Neither part has an unlocked multiplier, meaning overclocking via multiplier adjustment is not supported on either. The production status for both is active, and both were released in 2024. AMD launched on 2024-04-01, Intel on 2024-06-30, a gap of approximately three months.

The integrated graphics differ in name: AMD uses the Radeon 780M, Intel uses UHD Graphics 770. The database does not record any graphics benchmark scores, so no performance comparison of the iGPUs is possible. The presence of a Radeon 780M on the AMD side and UHD Graphics 770 on the Intel side is noted, but neither has measured scores in the database.

Architecture Differences

The two processors come from fundamentally different design lineages. AMD uses Zen 4 architecture on the Hawk Point codename, part of the 8000 series. Intel uses Raptor Lake architecture on the Raptor Lake-R codename, part of Core 14th Gen. The manufacturing process nodes differ substantially: AMD is built on a 4 nm process by TSMC, while Intel uses a 10 nm process by Intel. This process difference has implications for transistor density and power characteristics, though the database does not record measured power or density data beyond the listed figures.

AMD lists 25,000 million transistors on a 178 mm² die. Intel does not have a transistor count recorded, but lists a 257 mm² die size. The Intel die is 79 mm² larger than the AMD die, a 44.4% difference in physical area. Without Intel's transistor count, the density comparison cannot be completed. The process node difference (4 nm vs 10 nm) is the primary architectural separator, and it explains why AMD packs a comparable core count into a smaller die.

Cache hierarchies differ in both size and organization. AMD provides 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of shared L3 cache. Intel provides 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 36 MB of shared L3 cache. The Intel part has 25% more L1 per core (80 KB vs 64 KB), 100% more L2 per core (2 MB vs 1 MB), and 125% more L3 cache (36 MB vs 16 MB). The total L3 advantage for Intel is 20 MB. Neither part has 3D V-Cache, and neither lists a total L3 figure separate from the shared value.

The socket and platform targets differ completely. AMD uses AMD Socket FP8, a mobile-oriented socket. Intel uses Intel Socket 1700, a desktop socket. This reflects the market segment difference: AMD is listed as Mobile, Intel as Desktop. The platform implications are significant, though the database does not record motherboard compatibility details, chipset features, or platform power delivery specifications.

PCIe support differs by generation and lane count. AMD provides Gen 4 with 20 lanes (CPU only). Intel provides Gen 5 with 16 lanes (CPU only). The Intel part offers a newer PCIe generation with fewer lanes, while AMD offers an older generation with more lanes. The bandwidth per lane at Gen 5 is higher than Gen 4, but the database does not record aggregate PCIe bandwidth figures, so a total throughput comparison cannot be made numerically.

Memory support differs in flexibility. AMD supports only DDR5, while Intel supports both DDR4 and DDR5. Both use a dual-channel memory bus. AMD records 89.6 GB/s of memory bandwidth; Intel records no bandwidth figure. ECC memory is supported by both, a feature that matters for embedded and workstation use cases.

The integrated graphics solutions differ in name and presumably in architecture, but the database records no graphics specifications beyond the model names. AMD lists Radeon 780M, Intel lists UHD Graphics 770. No execution unit counts, clock speeds, or graphics memory allocations are recorded.

The Verdict

The database contains no benchmark scores for either processor, so the verdict must rest entirely on specification-level analysis. The recorded data shows two 8-core, 16-thread processors with ECC memory support and locked multipliers, but with divergent design targets. The AMD Ryzen Embedded 8840U is a mobile-class processor on AMD Socket FP8 with a 28 W TDP, a 4 nm TSMC process, and a smaller 178 mm² die. The Intel Core i9-14901TE is a desktop-class processor on Intel Socket 1700 with a 45 W TDP, a 10 nm Intel process, and a larger 257 mm² die.

For workloads that prioritize power efficiency, the recorded TDP figures favor the AMD part. At 28 W versus 45 W, the AMD processor consumes a lower thermal envelope by 17 W. The smaller die size and 4 nm process node also point toward a more power-conscious design. The AMD part additionally offers 20 PCIe Gen 4 lanes, which may suit systems requiring more expansion lanes at the older generation, and it has a recorded memory bandwidth of 89.6 GB/s.

For workloads that prioritize raw cache capacity and peak frequency, the Intel part holds the specification advantage. The Intel processor has a 0.40 GHz higher boost clock at 5.50 GHz, 20 MB more L3 cache (36 MB vs 16 MB), double the L2 cache per core (2 MB vs 1 MB), and 16 KB more L1 cache per core (80 KB vs 64 KB). It also supports both DDR4 and DDR5 memory, providing more memory compatibility options. The Intel part uses PCIe Gen 5, the newer generation, albeit with fewer lanes (16 vs 20).

The market segment classification is clear: AMD targets mobile platforms with Socket FP8, Intel targets desktop platforms with Socket 1700. A buyer choosing between these parts is first constrained by platform, not just performance. The mobile versus desktop distinction is the primary decision factor. Beyond that, the data indicates that Intel places its bets on large caches and high boost clocks within a 45 W envelope, while AMD places its bets on a lower power draw, a smaller die, and a higher base clock within a 28 W envelope. Neither part has recorded benchmark results, so no measured performance claim can be made. The selection between these two processors, based strictly on the database, depends on whether the platform requires a mobile socket (choose the AMD part) or a desktop socket (choose the Intel part), and whether the power envelope or the cache capacity carries more weight for the intended workload.
