Architecture Differences

The Intel Core i7-14700KF is built on Raptor Lake-R architecture, using Intel's 10 nm process with a die size of 257 mm². It is a desktop part with 20 cores and 28 threads. The AMD EPYC 7352 uses Zen 2 architecture, codenamed Rome, fabricated on TSMC's 7 nm process. That chip is a server/workstation part with 24 cores and 48 threads, and its physical package is far more complex: it uses 4 chiplets, each 74 mm², totaling 15,200 million transistors.

Cache layouts differ substantially. The Intel part provides 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3. The EPYC offers 96 KB of L1 per core, 512 KB of L2 per core, and 32 MB of L3 per die, which aggregates to 128 MB total L3. That massive aggregate cache is typical of server silicon, but the Intel chip's per-core L2 is four times larger.

Memory infrastructure is another clear divider. The Intel Core i7-14700KF supports both DDR4 and DDR5 in a dual-channel configuration. The EPYC 7352 supports only DDR4 but over an eight-channel memory bus, with a rated memory bandwidth of 204.8 GB/s. The Intel chip has no listed memory bandwidth figure.

PCIe capabilities also separate these two. The Intel part offers Gen 5 with 16 lanes from the CPU. The EPYC provides Gen 4 with 128 lanes from the CPU. That massive lane count reflects its server orientation. The Intel chip has an unlocked multiplier; the EPYC does not.

The Intel part runs on Socket 1700, while the EPYC uses Socket SP3. The Intel chip has a base clock of 3.40 GHz and boost of 5.60 GHz. The EPYC has a base clock of 2.30 GHz and boost of 3.20 GHz. The Intel chip draws 125 W TDP, the EPYC draws 155 W TDP.

Head-to-Head Benchmarks

The Intel Core i7-14700KF dominates the Cinebench suite. In Cinebench R15 multicore, it scores 4452 against 3458, a 28.7% lead. The same delta appears in R15 single-core (628 versus 488), R20 multicore (18550 versus 14411), R20 single-core (2618 versus 2034), R23 multicore (44167 versus 34314), and R23 single-core (6235 versus 4844). Every single Cinebench result shows the exact same 28.7% margin.

In Passmark multithread, the Intel part scores 52425 versus 40370, a 29.9% advantage. Floating-point math shows an even larger gap: 134393 versus 87969, which is 52.8% ahead. Integer math also favors Intel, 183056 versus 148605, a 23.2% lead. Physics tests go to Intel by 10.2%, with scores of 2961 versus 2688.

The EPYC's wins are narrower in overall system terms but meaningful in specialized workloads. Data encryption goes to AMD, 44426 versus 40046, a 9.9% edge. Prime number finding goes to AMD by a much larger margin, 301 versus 212, which is 29.6% ahead.

Some workloads are close. Extended instructions show Intel ahead by only 1.1%, with scores of 40660 versus 40203. Data compression is a 5.2% Intel win, 694963 versus 660712. Random string sorting is a 7.9% Intel win, 74723 versus 69231.

The single-thread story is not close. Intel's Passmark single-thread score of 4480 is more than double the EPYC's 1979, a 126.4% delta. That gap explains most of the application-level differences.

The Verdict

The data points to two very different design philosophies. The Intel Core i7-14700KF is a high-frequency desktop processor that wins on raw speed in most workloads. The AMD EPYC 7352 is a server processor built for throughput in specific parallel tasks, and it wins where its architecture has a natural advantage.

For a desktop builder, the Intel part is the rational choice. It wins 15 of 17 comparisons, includes a 126.4% single-thread advantage, and delivers a 52.8% lead in floating-point math. It also supports DDR5, which the EPYC cannot. The unlocked multiplier adds overclocking flexibility.

For a server or workstation buyer, the EPYC 7352 makes sense only if the workload matches its strengths. Data encryption and prime number finding are the two areas where it leads. The eight-channel memory bus and 128 MB of total L3 cache are not reflected in the benchmark scores here, but they matter for memory-bound server tasks. The EPYC also has 128 PCIe Gen 4 lanes, which is far beyond what the Intel desktop chip offers.

There is no universal winner. The database shows a clear performance leader in general computing, but the EPYC's specialized wins and platform-level features justify its existence in server racks.

Specification Differences

The two processors differ in almost every major specification. The Intel Core i7-14700KF has 20 cores and 28 threads, while the AMD EPYC 7352 has 24 cores and 48 threads. The Intel chip runs at 3.40 GHz base and 5.60 GHz boost; the EPYC runs at 2.30 GHz base and 3.20 GHz boost.

The Intel part is built on a 10 nm process with a 257 mm² die. The EPYC uses a 7 nm process from TSMC, with 15,200 million transistors spread across four 74 mm² chiplets. Cache differs: Intel has 80 KB L1 and 2 MB L2 per core, plus 33 MB shared L3. AMD has 96 KB L1 and 512 KB L2 per core, plus 32 MB per die and 128 MB total L3.

Memory support diverges completely. Intel supports DDR4 and DDR5 on a dual-channel bus. AMD supports only DDR4 on an eight-channel bus with 204.8 GB/s bandwidth. PCIe capability differs, with Intel providing Gen 5 at 16 lanes and AMD providing Gen 4 at 128 lanes. The Intel chip has an unlocked multiplier, the EPYC does not.

Socket and market segment also differ. Intel uses Socket 1700 and targets desktop. AMD uses Socket SP3 and targets server/workstation. The Intel part was released in 2023, the EPYC in 2019. TDP is 125 W for Intel and 155 W for AMD.

Where Each One Wins

The Intel Core i7-14700KF wins in every Cinebench test, both single-core and multi-core, by a consistent 28.7%. It also wins in Passmark multithread, floating-point math, integer math, physics, extended instructions, data compression, random string sorting, and single-thread tests. For any general-purpose computing task, rendering workload, or application that benefits from high clock speeds, the Intel part is the clear choice.

The AMD EPYC 7352 wins in exactly two recorded benchmarks: data encryption and prime number finding. The encryption win is modest at 9.9%, but the prime number win is substantial at 29.6%. These results suggest the EPYC's larger thread count and server-oriented cache hierarchy help in certain mathematical and cryptographic workloads.

For a workstation handling encryption or number-theoretic computations, the EPYC 7352 has a measurable edge. For everything else in the database, the Intel Core i7-14700KF is faster, often by a wide margin. The EPYC's platform advantages, such as 128 PCIe lanes and eight-channel memory, are not captured in these benchmark scores but remain relevant for systems that need massive I/O or memory bandwidth. The Intel chip is the better all-rounder; the EPYC is the better specialist.
