AMD Ryzen AI 7 445 vs Intel Core i5-14400T Comparison

The Intel Core i5-14400T and AMD Ryzen AI 7 445 are both 79th-percentile CPUs, but they achieve that standing through completely different strategies. The Intel part is a desktop chip built for sustained throughput, while the AMD part is a mobile chip tuned for efficiency and single-thread responsiveness. The benchmark data shows a clear split: the Intel Core i5-14400T dominates multi-threaded and compute-heavy workloads, winning 11 of the 15 head-to-head tests, while the AMD Ryzen AI 7 445 takes the remaining four, all of which are single-thread or extension-related tasks. Choosing between them means deciding whether your priority is raw parallel performance or a more balanced, power-lean mobile experience.

Where Each One Wins

The Intel Core i5-14400T is the undisputed king of multi-core workloads. Its most dramatic victory comes in Cinebench R23 multi-core, where it scores 17189 against the AMD's 10590, a 62.3% advantage. This pattern repeats across nearly every parallel benchmark. In PassMark multi-thread, Intel leads 20223 to 18115 (11.6% ahead). The gap widens further in floating-point math, where Intel scores 49139 versus 39362, a 24.8% margin, and in integer math, where it posts 65667 against 58332 (12.6% ahead). Data encryption shows a 25.9% lead (13244 vs 10519), and prime number finding shows a 30.4% advantage (73 vs 56). Even in physics simulations, Intel wins 1244 to 976, a 27.5% edge. These are not marginal differences; they are decisive wins in every category that scales with core count and cache.

The AMD Ryzen AI 7 445 wins the single-thread battles. In PassMark single-thread, it scores 3591 versus Intel's 3512, a 2.2% edge. Cinebench R15 single-core shows a larger 3.9% advantage (254 vs 244). The AMD chip also wins in extended instructions, scoring 15826 against Intel's 14562, an 8% lead. These wins are smaller in magnitude than Intel's multi-core victories, but they matter for latency-sensitive tasks and lightly-threaded applications. The AMD part's single-thread advantage is consistent across both PassMark and Cinebench R15, suggesting a genuinely stronger per-core design, despite having fewer cores.

The Verdict

Pick the Intel Core i5-14400T if your workloads are heavily parallel. The data is unambiguous: it is 62.3% faster in Cinebench R23 multi-core, 24.8% faster in floating-point math, and 25.9% faster in data encryption. This is a desktop processor with 10 cores and 16 threads, and it uses that hardware to crush every multi-threaded test. It also wins Cinebench R23 single-core by 34.3% (2426 vs 1806), which is a surprising result given the AMD part's other single-thread wins. If you are rendering, compiling, or running any workload that uses all cores, the Intel chip is the clear choice.

Pick the AMD Ryzen AI 7 445 if you need a mobile processor and care about per-core responsiveness. It wins the two most direct single-thread tests (PassMark single-thread and Cinebench R15 single-core) and the extended instructions test. Its 28W TDP is lower than Intel's 35W, making it a more power-efficient option for laptops. The AMD chip also supports LPDDR5X memory with 89.6 GB/s bandwidth, which the Intel desktop part does not. However, its multi-core performance is severely limited: it trails by 62.3% in Cinebench R23 multi-core and by 11.6% in PassMark multi-thread. If you need a laptop CPU for mixed use, the AMD part offers better single-thread performance, but it sacrifices a massive amount of multi-core throughput.

Head-to-Head Benchmarks

The single largest delta is Cinebench R23 multi-core, where Intel scores 17189 and AMD scores 10590. That 62.3% gap is the defining statistic of this comparison. It reflects the core count difference: Intel has 10 cores and 16 threads, while AMD has 6 cores and 12 threads. The Intel chip's 20MB of shared L3 cache also helps it feed those extra cores, whereas AMD has only 4MB of L3. In contrast, Cinebench R23 single-core shows Intel winning 2426 to 1806, a 34.3% margin that is surprising given AMD's other single-core wins. This test may favor Intel's higher 4.50 GHz boost clock over AMD's 4.60 GHz, or the difference may be due to the specific benchmark's instructions.

The PassMark suite reveals a consistent pattern. Intel wins data compression 235636 to 215812 (9.2% ahead), data encryption 13244 to 10519 (25.9% ahead), prime number finding 73 to 56 (30.4% ahead), floating-point math 49139 to 39362 (24.8% ahead), integer math 65667 to 58332 (12.6% ahead), multithread 20223 to 18115 (11.6% ahead), physics 1244 to 976 (27.5% ahead), and random string sorting 25181 to 23488 (7.2% ahead). AMD's only PassMark wins are single-thread (3591 vs 3512, 2.2% ahead) and extended instructions (15826 vs 14562, 8% ahead). The latter is notable because it measures SIMD and specialized instruction throughput, where AMD's Zen 5 architecture appears stronger. In Cinebench R15, Intel wins multi-core 1732 to 1723 (0.5% ahead), but AMD wins single-core 254 to 244 (3.9% ahead).

FAQ

A: The AMD Ryzen AI 7 445 features Radeon 840M integrated graphics, while the Intel Core i5-14400T features UHD Graphics 730. The benchmark data does not include graphics tests, so no performance comparison can be made from the provided facts.

Architecture Differences

The two chips come from fundamentally different design philosophies. The Intel Core i5-14400T is built on Raptor Lake architecture, specifically the Raptor Lake-R refresh, using a 10nm process node manufactured by Intel. It is a desktop part with a 215 mm² die size, designed for Intel Socket 1700. The AMD Ryzen AI 7 445 uses Zen 5 architecture, with the codename Gorgon Point, built on a 4nm process node manufactured by TSMC. It is a mobile part using AMD Socket FP8. The Intel chip's 10nm process is older and less dense than AMD's 4nm, which helps explain the AMD chip's lower TDP despite a higher boost clock.

The core configuration also differs significantly. Intel uses a hybrid design with 10 cores and 16 threads, which implies a mix of performance and efficiency cores typical of Raptor Lake. AMD uses 6 cores and 12 threads, with the generation noted as "Ryzen AI 400 (Zen 5 / Zen 5c)," indicating a mix of Zen 5 and Zen 5c cores. This hybrid approach on the AMD side likely contributes to its efficiency. The cache hierarchy differs as well: Intel provides 20MB of shared L3 cache, while AMD provides only 4MB. Intel's larger L3 cache is a major factor in its multi-threaded dominance, as it reduces the need to access slower system memory.

Specification Differences

The most obvious difference is core count: Intel has 10 cores and 16 threads, while AMD has 6 cores and 12 threads. Base clocks differ, with Intel at 1.50 GHz and AMD at 2.00 GHz, but boost clocks are close, with Intel at 4.50 GHz and AMD at 4.60 GHz. TDP is another key differentiator: Intel is rated at 35W, AMD at 28W. The process node favors AMD at 4nm versus Intel's 10nm. Die size is known for Intel at 215 mm², but not provided for AMD. Cache differs substantially: Intel has 1.25MB L2 per core and 20MB shared L3, while AMD has 1MB L2 per core and 4MB L3. Memory support differs: Intel supports DDR4 and DDR5, AMD supports DDR5 and LPDDR5X, with AMD specifying 89.6 GB/s bandwidth. PCIe lanes differ, with Intel offering Gen 5 with 16 lanes and AMD offering Gen 4 with 14 lanes. Integrated graphics differ: Intel uses UHD Graphics 730, AMD uses Radeon 840M. Sockets differ: Intel uses Socket 1700, AMD uses Socket FP8. Release dates are close, with Intel on January 7, 2024, and AMD on January 4, 2026. Intel has a launch MSRP of $221; AMD has no listed launch MSRP. Finally, the market segments differ: Intel is desktop, AMD is mobile.
