Architecture Differences

The architectural divide between these two processors is substantial. The Intel Core i5-14400T is built on Raptor Lake architecture, specifically the Raptor Lake-R refresh, using a 10 nm process node manufactured by Intel. It features a die size of 215 mm² and is based on a hybrid core design, which is evident in its 10 cores and 16 threads. The AMD EPYC 8024P, on the other hand, uses the Zen 4c architecture under the Siena codename, built on a 5 nm process node by TSMC, with a much smaller die size of 73 mm² and 8,875 million transistors.

Cache configurations differ notably. The Intel chip has an L1 cache of 80 KB per core, an L2 cache of 1.25 MB per core, and a shared L3 cache of 20 MB. The AMD EPYC 8024P has a smaller L1 at 64 KB per core and L2 at 1 MB per core, but a larger shared L3 cache of 32 MB. This larger L3 cache on the AMD part helps offset its lower clock speeds in some workloads.

Memory support is a defining difference. The Intel Core i5-14400T supports both DDR4 and DDR5 with a dual-channel memory bus, while the AMD EPYC 8024P supports only DDR5 but with a six-channel memory bus, delivering a theoretical bandwidth of 230.4 GB/s. PCIe connectivity also diverges sharply: the Intel chip offers Gen 5 with 16 lanes from the CPU, while the AMD EPYC provides Gen 5 with 96 lanes. Both support ECC memory, which is unusual for the Intel desktop segment.

The AMD EPYC also includes a larger transistor count and a more advanced process node, which contributes to its efficiency per core. The Intel part includes integrated graphics in the form of UHD Graphics 730, while the AMD EPYC has no integrated graphics at all. The thermal design power also differs dramatically: the Intel chip is rated at 35 W, while the AMD EPYC is rated at 90 W, reflecting their different target markets. The release dates are also separated, with the Intel chip launching in January 2024 and the AMD chip in September 2023.

Head-to-Head Benchmarks

The benchmark results reveal a clear pattern: the AMD EPYC 8024P consistently wins in Cinebench tests, while the Intel Core i5-14400T dominates in several PassMark workloads. In all six Cinebench tests, the AMD chip holds a narrow but consistent 1.6% advantage. This includes the Cinebench R23 multicore test, where the AMD scores 17472 against the Intel's 17189, and the single-core test where the AMD scores 2466 versus 2426.

The PassMark suite shows a more complex picture. The Intel Core i5-14400T wins the single-thread test by a massive 48.1% margin (3512 vs 2371), which is its largest victory. It also wins in floating-point math with a 41.4% advantage (49139 vs 34757), integer math with a 5.7% edge (65667 vs 62128), data compression by 1.5% (235636 vs 232242), and extended instructions by 2.2% (14562 vs 14251).

The AMD EPYC 8024P counters with wins in several specialized workloads. It leads in find prime numbers by 33% (109 vs 73), physics by 34.7% (1905 vs 1244), random string sorting by 27.2% (34613 vs 25181), and data encryption by 16.2% (15809 vs 13244). The PassMark multithread test shows the AMD chip winning by 1.6% (20556 vs 20223), consistent with its Cinebench performance.

The overall wins tally favors the AMD EPYC 8024P, which wins 10 of the 17 head-to-head benchmarks, while the Intel Core i5-14400T wins 6. However, the magnitude of the Intel victories in single-thread and floating-point math is much larger than the AMD's margins in most of its wins. The data suggests that the AMD chip is more consistent across a broad range of tests, but the Intel chip excels in specific areas that may matter more for certain applications.

The Verdict

The recorded data points to a clear split in use cases. The AMD EPYC 8024P is the better choice for server and workstation environments where memory bandwidth, multi-threaded consistency, and specialized workloads like encryption and physics simulations are critical. Its six-channel memory support and 96 PCIe lanes make it a formidable platform for data-heavy tasks, and its consistent 1.6% edge in Cinebench tests confirms its multi-core competence. The 33% lead in find prime numbers and the 34.7% lead in physics further solidify its position for scientific and cryptographic workloads.

The Intel Core i5-14400T, with its 48.1% lead in single-thread performance and 41.4% lead in floating-point math, is better suited for desktop applications where responsiveness and single-core speed are paramount. Its lower 35 W TDP also makes it a more power-efficient option for general-purpose computing. The 5.7% lead in integer math and 2.2% lead in extended instructions suggest it handles general-purpose code more efficiently. The data implies that for a desktop user prioritizing everyday speed, the Intel chip is the stronger option, while for a server administrator needing consistent throughput across a variety of tasks, the AMD EPYC is the safer bet.

Specification Differences

The two processors differ in nearly every core specification. The Intel Core i5-14400T has 10 cores and 16 threads, while the AMD EPYC 8024P has 8 cores and 16 threads. The base clock of the Intel chip is 1.50 GHz versus 2.40 GHz for the AMD, but the boost clock reverses this, with the Intel reaching 4.50 GHz versus the AMD's 3.00 GHz. The Intel chip is rated at 35 W TDP, while the AMD is rated at 90 W.

The process node and foundry also differ: Intel uses its own 10 nm process, while AMD uses TSMC's 5 nm process. The AMD chip has 8,875 million transistors and a 73 mm² die size, whereas the Intel chip has no listed transistor count and a 215 mm² die. Cache sizes vary as well, with the Intel chip offering 80 KB L1 per core, 1.25 MB L2 per core, and 20 MB shared L3, while the AMD chip has 64 KB L1 per core, 1 MB L2 per core, and 32 MB shared L3.

Memory support is a major divergence: the Intel chip supports DDR4 and DDR5 with a dual-channel bus, while the AMD chip supports only DDR5 with a six-channel bus and a listed bandwidth of 230.4 GB/s. PCIe lanes also differ, with Intel offering Gen 5, 16 lanes and AMD offering Gen 5, 96 lanes. The Intel chip includes UHD Graphics 730 integrated graphics, while the AMD chip has none. The market segment, socket, and release date also differ, with the Intel chip targeting desktop on Socket 1700 and the AMD chip targeting server/workstation on Socket SP6.

Where Each One Wins

The Intel Core i5-14400T wins in scenarios that demand high single-thread performance and floating-point computation. Its 48.1% lead in PassMark single-thread and 41.4% lead in floating-point math make it the clear choice for desktop productivity, general software development, and any application that relies on rapid single-core response. The 5.7% lead in integer math and 2.2% lead in extended instructions also make it competitive for everyday computing tasks. Its 35 W TDP suggests it can be used in compact, low-power desktop systems without sacrificing responsiveness.

The AMD EPYC 8024P wins in server-oriented workloads. Its 16.2% lead in data encryption and 33% lead in find prime numbers indicate strengths in security and cryptography. The 34.7% lead in physics and 27.2% lead in random string sorting point to advantages in simulation and data sorting tasks. The six-channel memory bus and 230.4 GB/s bandwidth provide a foundation for memory-intensive server applications, and the 96 PCIe lanes allow for extensive expansion. The AMD chip also holds a narrow but consistent 1.6% edge in all Cinebench tests and the PassMark multithread test, making it the more reliable choice for sustained multi-core workloads.
