AMD Ryzen 7 5700X vs Intel Core i5-14400T Comparison

The Intel Core i5-14400T and AMD Ryzen 7 5700X are both 79th-percentile desktop CPUs, but they achieve that status through opposite strategies. The Intel part leans on a massive single-core advantage in one rendering test, while the AMD chip dominates nearly every multi-threaded and encryption workload. The data shows a clear split: the 5700X wins 11 of the 15 head-to-head benchmarks, yet the 14400T takes the most lopsided victory. The decision between them hinges entirely on whether your priority is raw multi-core grunt or specific rendering and single-thread performance.

Head-to-Head Benchmarks

The single most striking result is in Cinebench R23 multi-core, where the Intel Core i5-14400T scores 17189 against the AMD Ryzen 7 5700X’s 13184, a 30.4% lead. That is the largest margin in either direction across the entire benchmark set. The Intel chip also wins Cinebench R23 single-core by an enormous 61.8%, posting 2426 versus 1499. These two results alone define the Intel case: if your workload is Cinebench, the 14400T is the clear choice.

However, the AMD Ryzen 7 5700X sweeps nearly everything else. In the older Cinebench R15 multi-core test, the AMD chip scores 2329 against Intel’s 1732, a 25.6% advantage. The single-core gap in R15 is smaller but still favors AMD, 253 versus 244, a 3.6% edge. This reversal between R15 and R23 is notable; the newer benchmark clearly favors the Intel architecture’s boost behavior.

Looking at PassMark results, the AMD chip is consistently ahead. Data compression shows a 27.2% lead (323610 vs 235636), data encryption a 34.4% lead (20198 vs 13244), and extended instructions a 33.1% lead (21755 vs 14562). The gap narrows for floating-point math, where AMD wins by only 5.2% (51842 vs 49139), but integer math is a different story: AMD takes a 29.2% lead (92749 vs 65667). Find prime numbers is the most one-sided AMD win at 38.7% (119 vs 73), and multithread shows a 24% gap (26612 vs 20223). Random string sorting goes AMD’s way by 24.9% (33512 vs 25181), and physics by 7% (1337 vs 1244).

The Intel chip does manage to win the two identical PassMark single-thread tests, scoring 3512 against AMD’s 3385, a 3.8% margin. That is a minor victory, though, compared to the Cinebench R23 single-core blowout. In total, Intel wins 4 benchmarks (Cinebench R23 multi and single, plus the two PassMark single-thread entries), while AMD wins 11.

Where Each One Wins

The AMD Ryzen 7 5700X is the workhorse for general compute tasks. The PassMark suite shows it ahead in every category except single-thread, with particularly strong results in encryption (34.4% faster), prime number finding (38.7% faster), and integer math (29.2% faster). For data-heavy workloads like compression and sorting, it also holds a clear edge of roughly 25%. This pattern suggests the 5700X handles sustained, multi-threaded workloads with more efficiency, despite having only 8 cores versus Intel’s 10.

The Intel Core i5-14400T is the specialist for rendering and lightly-threaded tasks. Its Cinebench R23 multi-core lead of 30.4% shows that in the right benchmark, the combination of 10 cores and 16 threads can outperform the AMD part decisively. The 61.8% lead in R23 single-core is even more striking, indicating that the Intel chip’s turbo behavior in that specific test is far more aggressive. The PassMark single-thread win, though smaller at 3.8%, confirms that Intel has a slight edge in basic single-core throughput.

For mixed workloads, the data favors AMD. The 5700X wins the PassMark multithread test by 24% and the physics test by 7%, indicating better general-purpose performance. The only area where Intel consistently wins is the Cinebench R23 family; outside of that, AMD is ahead in every other benchmark that both CPUs share.

Architecture Differences

The two processors come from different design philosophies. The Intel Core i5-14400T uses Raptor Lake architecture on a 10 nm process, while the AMD Ryzen 7 5700X uses Zen 3 on a 7 nm process from TSMC. The Intel chip has 10 cores and 16 threads, but the AMD chip has 8 cores and 16 threads, so they match on thread count while Intel brings two extra physical cores.

Cache layouts differ significantly. The Intel part provides 80 KB of L1 per core and 1.25 MB of L2 per core, with 20 MB of shared L3. The AMD chip has smaller per-core caches (64 KB L1 and 512 KB L2) but a larger shared L3 pool at 32 MB. This larger L3 could explain the AMD chip’s advantage in data compression and encryption, where larger working sets benefit from more cache.

Memory support also splits them. The Intel chip supports both DDR4 and DDR5, while the AMD chip is limited to DDR4. The AMD part lists a memory bandwidth of 51.2 GB/s, while the Intel part does not specify a number. Both use dual-channel memory and support ECC. PCIe connectivity differs as well: Intel offers Gen 5 with 16 lanes (CPU only), while AMD offers Gen 4 with 20 lanes (CPU only).

The Intel chip includes integrated graphics (UHD Graphics 730), which the AMD chip lacks entirely. The AMD chip has an unlocked multiplier for overclocking, while the Intel chip is locked. The Intel die is larger at 215 mm², while the AMD die is 74 mm²; the AMD chip lists 4,150 million transistors, while the Intel chip does not disclose a count.

The Verdict

Choose the AMD Ryzen 7 5700X if your primary concern is broad multi-threaded performance. The data shows it wins 11 of 15 shared benchmarks, with leads of 24-38% in encryption, integer math, prime finding, and multithread tests. It is also the better choice for data compression and sorting, where it leads by roughly 25%. The only single-thread test it loses is PassMark, and by just 3.8%. The 5700X also offers an unlocked multiplier for overclocking, which the Intel part does not.

Choose the Intel Core i5-14400T only if your workload specifically resembles Cinebench R23. The 30.4% multi-core lead and 61.8% single-core lead in that test are unmatched by any AMD advantage elsewhere. The Intel chip also holds a slight edge in PassMark single-thread (3.8%) and includes integrated graphics, which the AMD part lacks. However, the Intel chip is locked, uses a larger 10 nm process, and falls behind in every other shared benchmark. The trade-off is stark: you gain a massive Cinebench advantage and integrated graphics, but you lose on encryption, math, compression, and general multithread performance.

The average benchmark scores reflect this split. The Intel chip has an average score of 27166, while the AMD chip averages 27578, a difference of 1.5%. Both sit at the 79th percentile of all CPUs. The Intel part’s nearest rival is the Intel Core i9-9900K with a delta of 0.3%, while the AMD part’s nearest rival is the Intel Core i5-12600K with a delta of 0%. This suggests that despite the different benchmark distributions, the overall performance levels are comparable; the choice is about which benchmark family matters most to you.
