AMD Ryzen 5 7545U vs Intel Core i5-14400T Comparison

The Intel Core i5-14400T and AMD Ryzen 5 7545U are exceptionally close competitors in aggregate performance, with the Intel part averaging a benchmark score of 27166 against the AMD's 26849, a gap of roughly 1%. Both sit at the 79th percentile among all CPUs, and their nearest rivals confirm the parity: the i5-14400T trails the Intel Core i7-13700H by -0.7% and leads the AMD Ryzen 7 5700G by 0.4%, while the Ryzen 5 7545U is -0.2% behind the Intel Core i7-1370P and 0.4% ahead of the AMD Ryzen 5 5500GT. The decisive factor is not overall speed but workload-specific behavior: the AMD chip wins 13 of 17 head-to-head tests, including every Cinebench iteration, yet the Intel chip counters with massive wins in floating-point math and a clear edge in prime-number finding. This is a split decision where the Ryzen 5 7545U is the more consistent all-rounder, while the Core i5-14400T is the specialist for mathematically intensive tasks.

Where Each One Wins

The AMD Ryzen 5 7545U takes the crown in virtually every synthetic render and general productivity benchmark. Across Cinebench R15, R20, and R23, the AMD part wins both single-core and multi-core runs, albeit by a razor-thin -0.4% margin in each case. That consistency extends to PassMark's multithread test, where the Ryzen scores 20298 versus Intel's 20223, and to data compression, encryption, random string sorting, and single-thread tests. The AMD's largest victory is in extended instructions, where it posts 17865 against Intel's 14562, a commanding 18.5% lead. It also wins data encryption by 6.7% and random string sorting by 17.1%, making it the clear choice for cryptographic work and sorting-heavy data pipelines.

The Intel Core i5-14400T wins exactly four tests, but they are decisive in their domains. Its most striking victory is in floating-point math, where it scores 49139 against AMD's 36754 — a 33.7% advantage that is the largest delta in the entire comparison. It also leads integer math by 9.1% (65667 vs 60206), physics by 17.7% (1244 vs 1057), and find prime numbers by 7.4% (73 vs 68). These results point to a CPU that excels at raw computational throughput, particularly in workloads that stress arithmetic logic units rather than memory bandwidth or branch prediction. For users running simulations, scientific computing, or any task dominated by floating-point operations, the Intel part is the definitive winner.

FAQ

Q: Which CPU is faster in Cinebench R23 multi-core?

A: The AMD Ryzen 5 7545U wins by a marginal -0.4%, scoring 17253 versus the Intel Core i5-14400T's 17189. This is a 64-point difference, which is negligible in real-world rendering.

Q: How do the two compare in single-threaded performance?

Q: Do both CPUs support ECC memory?

A: Yes, both the Intel Core i5-14400T and the AMD Ryzen 5 7545U list ECC memory support, making them suitable for workstation-class builds where data integrity is critical.

Head-to-Head Benchmarks

The most lopsided result in this comparison is floating-point math, where the Intel Core i5-14400T delivers 49139 points against the AMD's 36754, a 33.7% blowout. This single test is the primary reason Intel's aggregate score is higher despite losing most individual benchmarks. In integer math, Intel extends its lead with 65667 versus 60206, a 9.1% margin, and in physics it posts 1244 against 1057, a 17.7% advantage. The prime-number test is closer but still Intel-favored: 73 versus 68, a 7.4% lead.

The AMD Ryzen 5 7545U counters with a different set of strengths. Its most dominant win is in extended instructions, where it scores 17865 against Intel's 14562 — an 18.5% gap that suggests superior SIMD or specialized instruction handling. Random string sorting also heavily favors AMD at 30358 versus 25181, a 17.1% lead. Data encryption goes AMD's way by 6.7% (14202 vs 13244), and data compression by 1.1% (238345 vs 235636). In the Cinebench suite, AMD wins all six tests — R15, R20, and R23, both single and multi-core — but every win is exactly -0.4%, indicating the two chips are nearly identical in rendering workloads. The same -0.4% margin appears in PassMark multithread (20298 vs 20223), while PassMark single-thread shows a slightly larger AMD advantage of 4.4% (3673 vs 3512).

Specification Differences

The two processors diverge significantly in core configuration. The Intel Core i5-14400T packs 10 cores and 16 threads, while the AMD Ryzen 5 7545U has 6 cores and 12 threads. Clock speeds favor AMD: the Ryzen has a 3.20 GHz base and 4.90 GHz boost, compared to Intel's 1.50 GHz base and 4.50 GHz boost. Thermal design power also differs, with Intel rated at 35W and AMD at 28W. The Intel part uses the LGA 1700 socket, whereas AMD uses the FP7 socket, reflecting their desktop versus mobile market segments. Memory support is another differentiator: Intel supports both DDR4 and DDR5, while AMD supports only DDR5. The AMD chip has a specified memory bandwidth of 89.6 GB/s, while Intel's is not listed. PCIe capabilities favor Intel with Gen 5 and 16 lanes, against AMD's Gen 4 and 14 lanes. Integrated graphics differ as well: Intel pairs with UHD Graphics 730, AMD with Radeon 740M.

Architecture Differences

The architectural gap is stark. Intel's Core i5-14400T is built on Raptor Lake, a 10 nm process from Intel's own foundry, with a die size of 215 mm². AMD's Ryzen 5 7545U uses Zen 4 architecture on a 4 nm TSMC process, with a die size of 137 mm² and 20,900 million transistors. The process node difference is significant: 10 nm versus 4 nm translates to a much denser and more power-efficient design for AMD. Cache hierarchies also differ: Intel provides 80 KB of L1 and 1.25 MB of L2 per core, plus 20 MB of shared L3, while AMD offers 64 KB of L1 and 1 MB of L2 per core, with 16 MB of shared L3. The Intel chip has a larger L3 pool by 4 MB, but the AMD part compensates with a smaller, more efficient core design. The Intel part is codenamed Raptor Lake-R and belongs to the Core 14th Gen (Raptor Lake Refresh) generation, while AMD's is codenamed Phoenix2 and belongs to the Ryzen 5 (Zen 4 Phoenix) generation. Both have locked multipliers, and both support ECC memory, but their architectural philosophies differ: Intel relies on more cores and a larger cache, while AMD leverages a leading-edge process and higher clock speeds.

The Verdict

The data points to a clear but nuanced recommendation. If the workload is dominated by floating-point math, integer math, or physics simulations, the Intel Core i5-14400T is the unequivocal choice — its 33.7% lead in floating-point and 17.7% lead in physics are too large to ignore. The same applies to prime-number finding, where Intel holds a 7.4% edge. These wins are substantial enough to justify the Intel part for scientific computing, financial modeling, or any task that stresses arithmetic throughput.

For everything else, the AMD Ryzen 5 7545U is the better buy. It wins 13 of 17 tests, including all Cinebench renders, multithread, single-thread, data compression, encryption, and sorting. Its 18.5% lead in extended instructions and 17.1% lead in random string sorting are particularly notable for developers and data analysts. The AMD chip also does this at a lower 28W TDP versus Intel's 35W, on a more advanced 4 nm process, and with a higher boost clock of 4.90 GHz. The aggregate benchmark scores are nearly identical — 27166 for Intel versus 26849 for AMD — but the AMD part achieves parity with fewer cores (6 vs 10) and threads (12 vs 16), showcasing superior per-core efficiency. The verdict is straightforward: choose the Intel Core i5-14400T for math-intensive desktop workloads, and the AMD Ryzen 5 7545U for everything else, especially mobile use cases where its lower power draw and smaller die size are advantages.
