AMD Ryzen AI 5 340 vs Intel Core i5-14401E Comparison

Head-to-Head Benchmarks

The head-to-head data shows a clear split between these two processors. Intel's Core i5-14401E takes three of the four shared benchmark comparisons, while AMD's Ryzen AI 5 340 wins only one.

The single AMD victory comes in Cinebench R15 multi-core, where the Ryzen AI 5 340 scores 1915 against Intel's 1830, a 4.6% advantage. This is a modest win, and it reflects a workload where the AMD chip can keep all six cores fully engaged without hitting power or thermal limits that would cause frequency drops.

Intel responds decisively in the other three tests. In Cinebench R15 single-core, the Core i5-14401E scores 258 against AMD's 242.6, a 6% lead. The gap widens substantially in Cinebench R23. Intel scores 18161 in multi-core versus AMD's 12532, which is a 31% advantage. The single-core R23 result shows Intel at 2564 versus AMD's 1915.5, a 25.3% lead.

The R23 multi-core result is particularly striking. A 31% deficit for AMD in that test suggests the Ryzen AI 5 340's performance collapses under sustained all-core load, likely due to its 28W TDP limiting boost behavior. The Intel part, with its 65W TDP, can maintain higher clocks across all cores for longer periods. That difference in sustained throughput is the single largest measurable gap between these two chips.

The R23 single-core delta of 25.3% is also significant. Intel's architecture delivers noticeably higher per-thread performance in this workload, which carries implications for lightly threaded applications.

Architecture Differences

The two processors come from fundamentally different design philosophies. AMD's Ryzen AI 5 340 uses Zen 5 architecture on TSMC's 4nm process, with the Krackan Point codename and a die size of 195 mm². Intel's Core i5-14401E uses Raptor Lake architecture on Intel's 10nm process, with the Raptor Lake-R codename and a 215 mm² die.

Both chips have 6 cores and 12 threads, so thread counts match. Cache configurations differ significantly. AMD provides 80 KB of L1 per core and 1 MB of L2 per core, with 8 MB of shared L3. Intel also uses 80 KB of L1 per core but has 1.25 MB of L2 per core and 20 MB of shared L3. Intel's larger L3 cache, 20 MB versus 8 MB, gives it a substantial capacity advantage for workloads that repeatedly access a working set larger than 8 MB.

Base and boost clocks tell a different story. AMD's base clock is 2.00 GHz with a boost of 4.80 GHz. Intel's base is 2.50 GHz with a boost of 4.70 GHz. Intel starts from a higher base frequency, while AMD has a slightly higher peak boost. Power envelopes are far apart: AMD's TDP is 28W, Intel's is 65W. That 37W difference explains much of the sustained performance gap in multi-core tests.

Memory support diverges as well. AMD supports DDR5 and LPDDR5X with a dual-channel bus and 89.6 GB/s of memory bandwidth. Intel supports DDR4 and DDR5, also dual-channel, but no bandwidth figure is recorded in the database. Intel supports ECC memory; AMD does not.

PCIe generation differs too. AMD uses Gen 4 with 16 lanes from the CPU. Intel uses Gen 5 with 16 lanes from the CPU. Integrated graphics also differ: AMD has the Radeon 840M, Intel has UHD Graphics 730.

The socket and market segments are completely different. AMD uses Socket FP8 and targets mobile. Intel uses Socket 1700 and targets desktop. AMD's release date is January 5, 2025; Intel's is June 30, 2024. Both are currently in active production.

Where Each One Wins

The benchmark data points toward distinct use cases for each processor.

Intel's Core i5-14401E wins in sustained multi-core throughput. The 31% lead in Cinebench R23 multi-core indicates that for rendering, video encoding, compilation, or any workload that runs all cores for extended periods, Intel delivers substantially more work per unit of time. The 65W TDP gives it the thermal headroom to keep clocks elevated. The 20 MB of L3 cache also helps with data-heavy workloads that benefit from larger on-die storage.

Intel also wins in single-thread performance. Its 6% lead in R15 single-core and 25.3% lead in R23 single-core show that for applications that depend on one heavily loaded thread, such as older games, spreadsheet recalculation, or certain scripting workloads, Intel provides noticeably better responsiveness. The higher base clock of 2.50 GHz contributes to this advantage in bursty, short-duration single-thread workloads.

AMD's Ryzen AI 5 340 wins only in Cinebench R15 multi-core, where it edges Intel by 4.6%. This is a shorter-duration multi-threaded test compared to R23, and AMD's higher boost clock of 4.80 GHz allows it to perform well before sustained load causes thermal or power throttling. For brief multi-threaded bursts, AMD can keep pace or slightly exceed Intel.

AMD's platform advantages are qualitative rather than benchmark-driven. It uses a 4nm process, which typically translates to lower power draw for the same work. The 28W TDP makes it suitable for thin-and-light mobile designs. LPDDR5X support enables low-power memory configurations. These characteristics do not show up in the CPU benchmark scores directly, but they matter for system-level design decisions.

FAQ

The Verdict

The data supports different choices depending on the workload and platform constraints.

For desktop users who prioritize sustained multi-core performance and single-thread speed, the Intel Core i5-14401E is the better performer. Its 31% lead in Cinebench R23 multi-core and 25.3% lead in R23 single-core are decisive margins. The 65W TDP, larger 20 MB L3 cache, Gen 5 PCIe support, and ECC memory support all reinforce its position as a desktop-oriented processor built for heavy, continuous workloads. Anyone running rendering jobs, video exports, or software builds would see measurable time savings with Intel.

For mobile users who need a low-power processor with brief bursts of multi-core speed, the AMD Ryzen AI 5 340 has a role. Its 28W TDP suits compact laptops and thin systems. The 4.6% win in Cinebench R15 multi-core shows it can handle short multi-threaded tasks effectively. Its 4 nm process and LPDDR5X support enable energy-efficient system designs. The Radeon 840M integrated graphics may also provide different media capabilities than Intel's UHD Graphics 730, though the database does not include graphics benchmarks.

The percentile rankings reinforce this split. AMD sits at the 78th percentile among all CPUs in the database, while Intel sits at the 60th. However, the average benchmark score for AMD is 25981, which is far above Intel's 5253. That discrepancy stems from AMD having a much larger set of recorded benchmarks, including PassMark tests that Intel does not have in this dataset. The head-to-head results, which use only tests both chips ran, provide the more meaningful comparison.
