AMD Ryzen 7 8840HX vs Intel Core i5-14401E Comparison

The AMD Ryzen 7 8840HX and Intel Core i5-14401E occupy different positions in the database: AMD's part is a 12-core, 24-thread mobile processor with a base clock of 2.90 and a boost clock of 5.10, while Intel's part is a 6-core, 12-thread desktop processor with a base clock of 2.50 and a boost clock of 4.70. Their only recorded head-to-head results are Cinebench R23 multi-core and single-core, and the two chips split those tests. AMD wins multi-core by 39.1%, Intel wins single-core by 27.6%.

Head-to-Head Benchmarks

Direct comparison data consists of two Cinebench R23 results. In multi-core, the AMD Ryzen 7 8840HX scores 25265 and the Intel Core i5-14401E scores 18161, putting AMD ahead by 39.1%. In single-core, the Intel part scores 2564 and the AMD part scores 1857, a 27.6% lead for Intel (the database records the AMD delta as -27.6). The head-to-head win count is therefore one for each processor.

Placement data from the database adds context. AMD is at the 94th percentile of all CPUs with an average benchmark score of 71797. Its nearest rivals are Intel Core Ultra 7 265KF (71910, delta -0.2), Intel Xeon Platinum 8270 (71370, delta 0.6), Intel Xeon 6517P (72350, delta -0.8), and Intel Xeon 6724P (72396, delta -0.8). Intel is at the 60th percentile with an average benchmark score of 5253. Its nearest rivals are Intel Xeon E5-2699A v4 (5259, delta -0.1), Intel Core i7-11700B (5241, delta 0.2), Intel Core i9-10850K (5240, delta 0.2), and Intel Core i5-13400T (5210, delta 0.8).

These nearest-rival deltas are all small, between -0.8 and 0.8 for AMD and between -0.1 and 0.8 for Intel, so each part sits tightly within its own comparison group. The direct Cinebench R23 margins are much larger than those placement deltas, which makes the head-to-head results the more meaningful signal for choosing between these two specific processors.

Where Each One Wins

Based on the direct results, the AMD Ryzen 7 8840HX wins the multi-threaded workload category. The 25265 Cinebench R23 multi-core score is 39.1% higher than Intel's 18161, and that is the larger of the two recorded swings. The Intel Core i5-14401E wins the single-threaded workload category. The 2564 Cinebench R23 single-core score is 27.6% higher than AMD's 1857.

The AMD record also contains Passmark results, all of which are AMD-only in the database. These include integer math at 146506, floating point math at 86747, extended instructions at 36527, data compression at 496427, data encryption at 29919, random string sorting at 57971, multithread at 41732, physics at 2185, find prime numbers at 304, and single thread at 3958. The Intel record's benchmark list contains only Cinebench R15, R20, and R23 results, so those Passmark figures do not factor into the direct comparison. They do show where the AMD part produces its highest recorded throughput: data compression, integer math, and floating point math.

Architecture Differences

The two processors are built on different architectures. AMD uses Zen 4 with the Dragon Range codename, produced on a 5 nm process at TSMC. Intel uses Raptor Lake with the Raptor Lake-R codename, produced on a 10 nm process at Intel. AMD's die is recorded as 2x 71 mm² with 13,140 million transistors; Intel's die is recorded as 215 mm² with no transistor count listed.

Core and cache structures differ. AMD has 12 cores and 24 threads, with 64 KB of L1 per core, 1 MB of L2 per core, and 64 MB of shared L3. Intel has 6 cores and 12 threads, with 80 KB of L1 per core, 1.25 MB of L2 per core, and 20 MB of shared L3. The AMD part provides more cores and a larger L3 pool, while Intel provides larger per-core L1 and L2 allocations.

Platform support also differs. AMD supports DDR5 on a dual-channel bus with 83.2 GB/s memory bandwidth and no ECC support. Intel supports DDR4 and DDR5 on a dual-channel bus, has no memory bandwidth figure recorded, and lists ECC support as true. AMD exposes PCIe Gen 5 with 28 CPU lanes; Intel exposes PCIe Gen 5 with 16 CPU lanes. AMD uses AMD Socket FL1 and Radeon 610M integrated graphics; Intel uses Intel Socket 1700 and UHD Graphics 730. The AMD part is listed as Mobile and has an unlocked multiplier; the Intel part is listed as Desktop and has a locked multiplier.

The Verdict

The recorded data splits cleanly by workload type. AMD Ryzen 7 8840HX has the multi-core advantage, with a 39.1% Cinebench R23 multi-core lead and a 12-core, 24-thread configuration. Intel Core i5-14401E has the single-core advantage, with a 27.6% Cinebench R23 single-core lead. The database places AMD at the 94th percentile and Intel at the 60th percentile, and the two parts target different segments: Mobile for AMD, Desktop for Intel. The average benchmark scores of 71797 for AMD and 5253 for Intel come from different benchmark lists, so the direct Cinebench R23 results remain the primary comparison. For workloads that scale across many threads, the data supports the AMD part; for lightly threaded workloads, the data supports the Intel part.
