AMD Ryzen AI 7 450 vs Intel Core i5-14400T Comparison

Head-to-Head Benchmarks

The benchmark data presents a clear overall picture: the AMD Ryzen AI 7 450 secures 13 wins across the head-to-head tests, while the Intel Core i5-14400T takes only 2. The most dramatic margin belongs to the AMD part in Cinebench R15 multi-core, where it scores 2713 against Intel's 1732, a 56.6% advantage. That is a substantial lead for a workload that scales well across all cores, and it sets the tone for the rest of the comparison.

The multicore theme continues in Cinebench R23, though the gap narrows considerably. AMD scores 18316 versus Intel's 17189, a 6.6% edge. The smaller delta in the newer Cinebench version suggests the Intel part's hybrid core arrangement holds up better under sustained rendering loads than it does in the older R15 test. Still, the AMD processor wins both multi-core Cinebench iterations, which is the headline result for heavily threaded productivity work.

Single-core performance flips the script. The Intel Core i5-14400T leads in Cinebench R15 single-core with 244 points against AMD's 215, an 11.9% margin. The gap widens in Cinebench R23 single-core, where Intel posts 2426 versus AMD's 2038, a 16% advantage. This is a meaningful split: Intel's highest-performing core is clearly faster in lightly threaded rendering tasks, even though its overall package draws more power to reach those clocks.

PassMark's suite tells a different story, one that heavily favors AMD. The Ryzen AI 7 450 wins all ten PassMark tests included in the head-to-head set. The largest PassMark margin appears in extended instructions, where AMD scores 22400 against Intel's 14562, a 53.8% lead. Data compression shows a 34.1% advantage (315906 versus 235636), and integer math delivers a 34.8% edge (88531 versus 65667). Random string sorting goes to AMD by 41.6% (35648 versus 25181), and multithread performance lands 30.3% ahead (26350 versus 20223).

Even in tests where Intel's single-core Cinebench wins might suggest competitiveness, AMD holds PassMark single-thread supremacy. The Ryzen AI 7 450 scores 3901 in PassMark single-thread, beating Intel's 3512 by 11.1%. That result is notable because it contradicts the Cinebench single-core pattern, indicating the two processors respond differently to the specific instruction mixes and memory access patterns in each benchmark suite.

Other PassMark results reinforce AMD's dominance. Floating point math goes to AMD by 10.8% (54447 versus 49139), data encryption by 22.7% (16247 versus 13244), prime number finding by 21.9% (89 versus 73), and physics by 26.8% (1578 versus 1244). Across the entire PassMark set, AMD's smallest win is the 10.8% floating point margin, meaning Intel never comes within single digits in any PassMark test.

The aggregate data confirms the split. AMD's average benchmark score sits at 39485, placing it in the 87th percentile of all CPUs in the database. Intel's average is 27166, good for the 79th percentile. AMD's nearest rivals include the AMD Ryzen 7 PRO 8840HS at 39603 (-0.3%), the AMD Ryzen 7 PRO 8845HS at 39325 (0.4%), and the AMD Ryzen 7 9800X3D at 39768 (-0.7%). Intel's nearest rivals include the Intel Core i9-9900K at 27097 (0.3%), the AMD Ryzen 7 5700G at 27051 (0.4%), and the Intel Core i7-13700H at 27355 (-0.7%). Both processors sit within a narrow band of their respective peer groups, but AMD's peer group operates at a much higher absolute level.

Where Each One Wins

The AMD Ryzen AI 7 450 is the clear choice for multi-threaded and data-heavy workloads. Its Cinebench R15 multi-core lead of 56.6% indicates exceptional performance in older rendering workloads that scale aggressively across cores. The 30.3% PassMark multithread advantage reinforces this, as does the 34.1% lead in data compression. For users handling large archives, encrypted data, or integer-heavy calculations, AMD's 34.8% integer math edge and 22.7% encryption advantage make it the stronger option. The 53.8% extended instructions margin suggests the Zen 5 architecture executes complex instruction sequences far more efficiently than Intel's Raptor Lake design.

The AMD processor also wins the PassMark single-thread test by 11.1%, which means even some lightly threaded applications will run faster on the mobile-oriented AMD part. Its 10.8% floating point lead and 26.8% physics advantage cover scientific and simulation workloads. The 41.6% random string sorting margin points to strong memory subsystem performance during unpredictable access patterns.

The Intel Core i5-14400T claims only the two Cinebench single-core tests. Its 16% lead in Cinebench R23 single-core and 11.9% lead in R15 single-core make it the better option for older single-threaded rendering tasks, certain legacy applications, and workloads that depend heavily on one core's raw clock speed. The Intel part reaches a 4.50 GHz boost clock, which helps in these scenarios. However, its wins do not extend into PassMark's single-thread test, so the advantage is specific to Cinebench's rendering pipeline rather than a general single-core superiority.

For sustained all-core workloads, the data consistently favors AMD. The Cinebench R23 multi-core margin of 6.6% is modest, but the R15 margin is enormous, and PassMark's multithread test shows a 30.3% gap. The AMD part's 8 MB of L3 cache is smaller than Intel's 20 MB, yet the benchmark results show no penalty in the tests recorded here. The Ryzen AI 7 450 also runs at a 28 W TDP compared to Intel's 35 W, which makes its performance advantage more efficient per watt, though the data does not include direct power consumption measurements.

Specification Differences

The two processors differ across nearly every core specification. The AMD Ryzen AI 7 450 has 8 cores and 16 threads, while the Intel Core i5-14400T has 10 cores and 16 threads. Intel fields more physical cores, but AMD matches the thread count. Base clocks differ as well: AMD starts at 2.00 GHz, Intel at 1.50 GHz. Boost clocks favor AMD at 5.10 GHz versus Intel's 4.50 GHz.

Memory support diverges. AMD supports DDR5 and LPDDR5X, while Intel supports DDR4 and DDR5. Both use dual-channel memory buses. AMD lists a memory bandwidth of 89.6 GB/s; Intel does not have a recorded bandwidth figure. Both support ECC memory.

PCIe capabilities differ. AMD provides Gen 4 with 16 lanes (CPU only), while Intel provides Gen 5 with 16 lanes (CPU only). The integrated graphics differ as well: AMD uses the Radeon 860M, Intel uses UHD Graphics 730. Neither processor has an unlocked multiplier.

The platform targets differ. AMD uses the AMD Socket FP8, which is a mobile socket, and the processor is classified in the mobile market segment. Intel uses the Intel Socket 1700 and is classified in the desktop market segment. The AMD release date is 2026-01-04, while Intel's is 2024-01-07. Intel has a launch MSRP of $221; AMD has no recorded launch MSRP.

Architecture Differences

The architectural split is fundamental. AMD's Ryzen AI 7 450 uses the Zen 5 architecture under the Gorgon Point codename, part of the Ryzen AI 400 generation that combines Zen 5 and Zen 5c cores. Intel's Core i5-14400T uses Raptor Lake architecture under the Raptor Lake-R codename, part of the Core i5 generation based on the Raptor Lake Refresh.

Manufacturing processes differ sharply. AMD builds on a 4 nm process at TSMC, while Intel uses a 10 nm process at its own foundry. Die sizes are close: AMD measures 195 mm², Intel measures 215 mm². No transistor counts are recorded for either part.

Cache hierarchies show structural differences. Both allocate 80 KB of L1 cache per core. AMD provides 1 MB of L2 cache per core, while Intel provides 1.25 MB per core. The L3 cache arrangement is very different: AMD has 8 MB total, while Intel has 20 MB shared. The larger shared L3 on Intel may benefit certain workloads, though the benchmark data does not show Intel winning any multi-threaded tests in this comparison.

The feature sets reflect each platform's priorities. AMD's Zen 5 design targets efficiency and mobile integration, with a 28 W TDP and LPDDR5X support for thin-and-light systems. Intel's Raptor Lake design targets desktop flexibility, with DDR4 compatibility for older platforms and PCIe Gen 5 for high-bandwidth expansion. AMD's integrated Radeon 860M graphics represent a more capable iGPU solution for the mobile segment, while Intel's UHD Graphics 730 serves basic desktop display needs. The production status for both is Active, and both CPUs are listed with locked multipliers.
