AMD EPYC 4465P vs Intel Core i7-14700K Comparison

Intel Core i7-14700K and AMD EPYC 4465P represent two fundamentally different answers to the question of what a CPU should be. The Intel part is a high-core-count desktop processor built for maximum throughput in lightly threaded and heavily parallel consumer workloads, while the AMD EPYC is a power-efficient server chip from the Zen 5 family that dominates in single-threaded performance and long-form multi-threaded rendering. The benchmark data shows a near-even split, with Intel taking 9 wins and AMD taking 8 across the head-to-head tests, but the margins are highly asymmetric. Intel wins most of its tests by double-digit percentages, while AMD wins the two most modern Cinebench tests by even larger margins. The average benchmark scores place the Intel part at 69,355 versus 66,925 for the EPYC, a gap of about 3.6%, and both sit within 1% of their nearest rivals in the database. This is a contest between raw thread count and architectural efficiency.

Where Each One Wins

The Intel Core i7-14700K is the clear choice for workloads that stress memory bandwidth, encryption, compression, and floating-point math. The data shows a 20.4% lead in PassMark data compression and a 24.6% lead in data encryption, both of which are common in file archives, database operations, and security-related tasks. It also wins floating-point math by 26.8%, which matters for scientific simulations and financial modeling. The Intel chip dominates the older Cinebench R15 and R20 multi-core tests, taking 16.4% and 2.9% leads respectively, and it wins PassMark multi-thread by 5.1%. The 20 cores and 28 threads give it a structural advantage in any workload that scales linearly with core count but does not require the latest instruction set optimizations.

The AMD EPYC 4465P wins the modern Cinebench R23 tests by enormous margins, and that is where its value proposition lives. It scores 42,918 in R23 multi-core versus 33,440.5 for Intel, a 22.1% lead, and it nearly triples Intel's R23 single-core score with 6,059 versus 2,160, a 64.4% advantage. The Zen 5 architecture also wins PassMark extended instructions by 5.2%, find prime numbers by 37.3%, and physics by 18.7%. The single-thread PassMark score is 4,575 versus 4,472, a modest 2.3% lead. This makes the EPYC the better fit for code compilation, video encoding with modern codecs, and any workload that benefits from the newest vector instructions or a very strong single core. The gap in R23 is so wide that it outweighs Intel's wins in several smaller tests when comparing average scores.

Architecture Differences

The two processors are built on completely different foundations. Intel uses the Raptor Lake architecture on a 10 nm process, produced at Intel's own foundry, with a die size of 257 mm². AMD uses Zen 5, codenamed Grado, on a 4 nm process from TSMC, with a total die area of 2x 70.6 mm² and 16,630 million transistors. The Intel chip has 20 cores and 28 threads, which reflects its hybrid design of performance and efficiency cores, while the EPYC has 12 cores and 24 threads, all using the same Zen 5 cores. The base clocks are identical at 3.40 GHz, but the Intel boosts to 5.60 GHz versus 5.40 GHz for the EPYC.

Cache configurations differ sharply. Both have 80 KB of L1 per core, but Intel has 2 MB of L2 per core versus 1 MB for AMD. The L3 cache is where AMD takes a decisive lead: 64 MB shared versus 33 MB shared for Intel. That larger L3 helps the EPYC in workloads with large working sets, and it partially explains the R23 multi-core win despite having 8 fewer cores. Memory support also diverges. Intel supports both DDR4 and DDR5 in dual-channel mode, while AMD only supports DDR5, also dual-channel, but with a rated bandwidth of 89.6 GB/s. Both support ECC memory. The Intel chip has 16 PCIe Gen 5 lanes from the CPU, while AMD provides 24 Gen 5 lanes, which matters for server-style expansion.

The EPYC includes Radeon Graphics integrated, while Intel has UHD Graphics 770. Intel's multiplier is unlocked, the EPYC's is not. The EPYC targets the server and workstation segment, while the i7-14700K is a desktop part. The release dates are also far apart: Intel launched on October 16, 2023, and AMD on May 12, 2025, which explains the architectural generational gap.

Head-to-Head Benchmarks

The single largest win for Intel is in PassMark floating-point math, where it scores 134,222 versus 105,833, a 26.8% advantage. That is a decisive margin for any number-crunching application that relies on FPU throughput. Intel also takes data encryption by 24.6% (40,091 versus 32,184) and data compression by 20.4% (695,234 versus 577,210). The Cinebench R15 multi-core test gives Intel a 16.4% win (5,035 versus 4,326), which is notable because the EPYC is newer and more efficient, but the older test does not seem to benefit from Zen 5's strengths. PassMark random string sorting goes to Intel by 10.6% (74,733 versus 67,597), and integer math by 4.8% (182,876 versus 174,551). The multi-thread PassMark score favors Intel by 5.1% (52,392 versus 49,871).

The AMD EPYC's most striking result is the Cinebench R23 single-core score. At 6,059, it beats Intel's 2,160 by 64.4%, which is an enormous gap and reflects the massive IPC improvement of Zen 5 over Raptor Lake. The R23 multi-core score also heavily favors AMD: 42,918 versus 33,440.5, a 22.1% lead. Prime number finding goes to AMD by 37.3% (338 versus 212), and physics by 18.7% (3,647 versus 2,964). Extended instructions favor AMD by 5.2% (42,867 versus 40,632), and the single-thread PassMark tests show a 2.3% AMD lead (4,575 versus 4,472). The Cinebench R20 results are close, with Intel winning multi-core by 2.9% (18,544 versus 18,025) and single-core by 2.9% (2,617 versus 2,544), showing that the two chips are nearly tied in that generation of the test.

The pattern is consistent: Intel wins in older, more memory-bound or FPU-heavy tests, while AMD wins in the newest Cinebench tests and in tasks that benefit from its larger L3 and newer instruction set. The R15 single-core test is an outlier in the other direction, with AMD winning by 48.6% (610 versus 313.5), which suggests that the EPYC's cores are dramatically more efficient per clock even in legacy tests.

The Verdict

Choose the Intel Core i7-14700K if your primary workloads are data compression, encryption, floating-point math, or any application that uses the older Cinebench R15 and R20 versions. The 26.8% lead in floating-point math and 24.6% lead in encryption are not trivial, and the 5.1% multi-thread PassMark advantage shows it handles heavy parallel loads well. It also has an unlocked multiplier, which is a feature the EPYC lacks, and it supports both DDR4 and DDR5 memory, giving more flexibility in platform choice.

Choose the AMD EPYC 4465P if you run modern rendering, compilation, or any workload that is compiled with the latest instruction sets. The 64.4% single-core R23 lead and 22.1% multi-core R23 lead are the most relevant metrics for current software. The 64 MB L3 cache and 89.6 GB/s memory bandwidth provide a substantial buffer for data-heavy server tasks, and the 65 W TDP means it can deliver this performance in a much cooler, quieter system. The EPYC also has 24 PCIe Gen 5 lanes versus 16 for Intel, which is better for expansion cards and NVMe storage. If you care about the newest architectural efficiency and are willing to accept fewer cores, the EPYC is the superior processor in the tests that matter most for modern software.
