AMD Ryzen AI 7 345 vs Intel Core i5-14400T Comparison

Where Each One Wins

The AMD Ryzen AI 7 345 and Intel Core i5-14400T split their benchmark wins across distinct workload categories. The AMD part takes 6 of the 15 recorded head-to-head tests, while the Intel part claims 9. The pattern is clear: AMD wins in single-threaded responsiveness and specific data-processing tasks, while Intel dominates in multi-core rendering and compute-heavy workloads.

The AMD Ryzen AI 7 345 wins in Cinebench R15 single-core with an 11.1% margin, PassMark single-thread with 10.3%, extended instructions with 16.8%, data compression with 0.8%, and random string sorting with 1%. These results indicate the AMD design excels in latency-sensitive, per-thread performance and instruction-level efficiency. Its boost clock of 4.60 GHz, higher than the Intel part's 4.50 GHz, aligns with these single-thread victories.

The Intel Core i5-14400T wins in Cinebench R23 multi-core by 33.3%, Cinebench R15 multi-core by 1.2%, Cinebench R23 single-core by 25.1%, data encryption by 10.8%, find prime numbers by 15.1%, floating point math by 13.3%, integer math by 3.3%, PassMark multithread by 1.5%, and physics by 12.5%. The Intel part's 10 cores and 16 threads give it a structural advantage in parallel workloads, while its 20 MB shared L3 cache supports its single-core Cinebench R23 lead.

For use-case planning, the AMD processor fits interactive tasks, encryption-adjacent data handling, and applications that reward high instruction throughput per clock. The Intel processor fits rendering, physics simulation, and multi-threaded productivity where core count translates directly to throughput.

Head-to-Head Benchmarks

The largest single margin in the comparison is Cinebench R23 multi-core, where Intel leads 17189 to 11461, a 33.3% difference. This test benefits directly from Intel's 10 cores and 16 threads. The AMD part, with 6 cores and 12 threads, cannot match parallel throughput in this workload. The gap is substantial enough to define the Intel part as the clear choice for multi-core rendering tasks.

Cinebench R23 single-core reverses the picture somewhat, but still favors Intel: 2426 to 1818, a 25.1% Intel lead. This is notable because AMD wins the other two single-core tests. The discrepancy suggests the Cinebench R23 workload responds to Intel's higher per-core L2 cache (1.25 MB per core versus 1 MB per core) and its 10 nm process characteristics.

The AMD part's strongest win is PassMark extended instructions: 17003 versus 14562, a 16.8% margin. This test measures CPU extensions and specialized instruction throughput, where the AMD Zen 5 architecture shows clear superiority. In PassMark single-thread, AMD leads 3875 to 3512, a 10.3% margin. Cinebench R15 single-core also goes to AMD: 271 to 244, an 11.1% lead.

In data compression, AMD edges Intel 237484 to 235636, a 0.8% margin. Random string sorting also favors AMD: 25435 to 25181, a 1% lead. These are narrow wins, indicating near-parity in memory-bound string and compression workloads.

Intel's remaining wins include data encryption (13244 versus 11814, a 10.8% lead), find prime numbers (73 versus 62, a 15.1% lead), floating point math (49139 versus 42621, a 13.3% lead), integer math (65667 versus 63475, a 3.3% lead), physics (1244 versus 1089, a 12.5% lead), and Cinebench R15 multi-core (1732 versus 1712, a 1.2% lead). PassMark multithread is close: 20223 versus 19927, a 1.5% Intel lead.

The overall average benchmark score tells a different story than the head-to-head wins. AMD's average is 29461, while Intel's is 27166. AMD ranks in the 81st percentile versus Intel's 79th. The AMD part's nearest rivals include the AMD Ryzen 7 3800X (avg 29447, 0% delta) and the AMD EPYC 9654 (avg 29409, 0.2% delta). Intel's nearest rivals include the Intel Core i9-9900K (avg 27097, 0.3% delta) and the AMD Ryzen 7 5700G (avg 27051, 0.4% delta).

Specification Differences

The two processors differ across fundamental specifications. The AMD Ryzen AI 7 345 uses 6 cores and 12 threads. The Intel Core i5-14400T uses 10 cores and 16 threads. Base clocks differ: AMD at 2.00 GHz versus Intel at 1.50 GHz. Boost clocks are closer: AMD at 4.60 GHz versus Intel at 4.50 GHz.

Thermal design power favors AMD: 28 watts versus 35 watts for Intel. Sockets are incompatible: AMD uses AMD Socket FP8, Intel uses Intel Socket 1700. The AMD part is classified as mobile, while the Intel part is desktop. Both have locked multipliers.

Memory support diverges. AMD supports DDR5 and LPDDR5X with dual-channel configuration and 89.6 GB/s bandwidth. Intel supports DDR4 and DDR5 with dual-channel configuration; no bandwidth figure is recorded. ECC memory is supported only on the Intel part.

PCIe lanes differ: AMD provides Gen 4 with 14 lanes (CPU only), Intel provides Gen 5 with 16 lanes (CPU only). Integrated graphics differ: AMD uses Radeon 840M, Intel uses UHD Graphics 730. The Intel part has a recorded launch MSRP of $221. The AMD part has no recorded launch MSRP.

Cache structures differ. Both have 80 KB L1 per core. L2 cache is 1 MB per core on AMD versus 1.25 MB per core on Intel. L3 cache is 4 MB on AMD versus 20 MB shared on Intel. The Intel part's larger L3 cache aligns with its Cinebench R23 single-core advantage.

Release dates differ: AMD on 2025-01-14, Intel on 2024-01-07. Both are active production parts. Part numbers are 100-000002122 for AMD and SRN3N for Intel.

Architecture Differences

The AMD Ryzen AI 7 345 uses the Krackan Point codename from the Ryzen AI 300 generation, built on Zen 5 and Zen 5c cores. The Intel Core i5-14400T uses Raptor Lake architecture, specifically Raptor Lake-R, from the Core 14th Gen series with a Raptor Lake Refresh generation label.

Process nodes differ significantly. AMD uses a 4 nm process from TSMC. Intel uses a 10 nm process from its own foundry. This process difference contributes to AMD's lower TDP (28 watts versus 35 watts) despite the mobile form factor. The AMD die lacks a recorded size, while Intel records a 215 mm² die size.

The core designs reflect different philosophies. AMD uses a hybrid of Zen 5 and Zen 5c cores within the Ryzen AI 300 generation, combining full-performance and compact-efficiency cores. Intel uses a Raptor Lake refresh design with its own hybrid core arrangement, though the database does not record the specific core types.

Cache architecture highlights the contrast. Intel's 20 MB shared L3 cache is five times larger than AMD's 4 MB L3. Per-core L2 cache is also larger on Intel at 1.25 MB versus 1 MB. AMD compensates with a higher boost clock (4.60 GHz versus 4.50 GHz) and a lower base clock advantage (2.00 GHz versus 1.50 GHz).

The integrated graphics differ by vendor and capability. AMD pairs Radeon 840M with its mobile design, while Intel uses UHD Graphics 730 for desktop. The PCIe generation difference (Gen 4 on AMD, Gen 5 on Intel) reflects their respective platform generations. Memory controller differences are visible: AMD targets DDR5 and LPDDR5X with a measured 89.6 GB/s bandwidth, Intel supports both DDR4 and DDR5 with no recorded bandwidth figure.

The production status for both is active. The AMD part's market segment is mobile, the Intel part's is desktop. The architecture differences explain the benchmark split: Intel's larger cache and core count drive multi-core wins, while AMD's newer process and higher boost clock drive single-thread and instruction-extension wins.
