AMD EPYC 7713P vs Intel Core i5-1345U Comparison

The AMD EPYC 7713P and Intel Core i5-1345U occupy opposite ends of the computing spectrum, one a 64-core server behemoth and the other a 10-core mobile processor. The recorded data shows a complete sweep for the EPYC in Cinebench testing, but the real story lies in what each chip is designed to do. This analysis breaks down the benchmark results, architectural choices, and specification differences to clarify which processor fits which workload.

Where Each One Wins

The head-to-head benchmark data is unambiguous: the AMD EPYC 7713P wins all six recorded Cinebench tests, with winsA at 6 and winsB at 0. The EPYC's dominance is most pronounced in multi-core workloads, where its 64 cores and 128 threads produce scores that dwarf the mobile chip. In Cinebench R23 multi-core, the EPYC scores 69229 against the i5-1345U's 7724, a delta of 796.3%. This is a processor built for massive parallel throughput, and the data reflects that.

The Intel Core i5-1345U, despite losing every head-to-head comparison, has its own strengths in the broader database. Its Passmark results show a different character. The i5-1345U scores 164005 in data compression, 10288 in data encryption, and 9178 in extended instructions. These are not server-class numbers, but they represent a capable mobile processor for everyday tasks. Its single-thread Passmark score of 3415 and floating point math score of 35939 indicate a chip that handles responsive, interactive workloads well. The i5-1345U wins in the mobile segment where power efficiency and integrated graphics matter, not in raw compute density.

The use-case split is clear. The EPYC 7713P is for server racks, virtualization hosts, and compute-heavy workloads that scale across many cores. The i5-1345U is for laptops and compact systems where the 15 W TDP and integrated Iris Xe Graphics 80EU make it a practical choice for general productivity, media consumption, and light content creation.

Architecture Differences

The two processors come from different design philosophies. The AMD EPYC 7713P uses the Zen 3 architecture, codenamed Milan, built on a 7 nm process at TSMC. It packs 33,200 million transistors across a die size of 8x 81 mm². The Intel Core i5-1345U uses Raptor Lake architecture, specifically Raptor Lake-U, built on a 10 nm process at Intel. The EPYC is a server-class chip with a 225 W TDP, while the i5-1345U is a mobile chip with a 15 W TDP, a 15x difference in power envelope.

Cache hierarchies differ substantially. The EPYC 7713P has 64 KB of L1 cache per core, 512 KB of L2 per core, and a massive 256 MB of shared L3 cache. The i5-1345U has 80 KB of L1 per core, 1.25 MB of L2 per core, and 12 MB of shared L3. The EPYC's 256 MB L3 is a key advantage for workloads with large working sets, while the i5's smaller cache is adequate for mobile tasks.

Memory support also diverges. The EPYC 7713P supports DDR4 memory over an eight-channel bus with 204.8 GB/s of bandwidth and ECC memory. The i5-1345U supports both DDR4 and DDR5 over a dual-channel bus, with no ECC support. The EPYC's eight-channel memory subsystem is designed for bandwidth-hungry server workloads, while the i5's dual-channel setup is standard for mobile platforms.

PCIe connectivity further separates them. The EPYC 7713P offers Gen 4 with 128 lanes, while the i5-1345U offers Gen 4 with 8 lanes. The EPYC's lane count enables massive I/O expansion for storage arrays, networking, and accelerators. The i5's 8 lanes are sufficient for a laptop's GPU and NVMe drive.

Head-to-Head Benchmarks

The Cinebench results show a consistent pattern of EPYC dominance. In Cinebench R15 multi-core, the EPYC scores 6978 against the i5's 1311, a 432.3% advantage. Single-core R15 shows the EPYC at 984 versus 240, a 310% lead. This single-core gap is notable because it shows the EPYC's Zen 3 cores are not just numerous, they are individually faster than the i5's Raptor Lake cores in this test.

Cinebench R20 amplifies the multi-core gap. The EPYC scores 29076 versus 4942, a 488.3% delta. Single-core R20 shows 4104 versus 697, a 488.8% delta. The consistency of the single-core and multi-core deltas in R20 suggests the EPYC's per-core performance is roughly 4.9x better than the i5 in this workload.

Cinebench R23 delivers the largest margin. Multi-core shows 69229 for the EPYC versus 7724 for the i5, a 796.3% delta. This is the biggest win in the entire dataset. Single-core R23 shows 9773 versus 1724, a 466.9% delta. The R23 multi-core result is particularly striking because it reflects the combined effect of more cores and faster cores.

The i5-1345U's Passmark results provide context for its intended role. Its data compression score of 164005 and integer math score of 52847 show a chip that handles everyday number crunching well. Its multithread score of 14511 and physics score of 818 are modest, but appropriate for a 15 W mobile part. The EPYC has no Passmark results in this dataset, so direct comparison in those tests is not possible.

Specification Differences

The two processors differ in nearly every specification category. The EPYC 7713P has 64 cores and 128 threads, while the i5-1345U has 10 cores and 12 threads. Base clocks are 2000 MHz for the EPYC and 1600 MHz for the i5, but boost clocks favor Intel at 4.70 GHz versus 3.68 GHz. The EPYC's lower boost clock is a trade-off for its 225 W TDP, while the i5's higher boost clock serves its 15 W mobile design.

Socket and platform differ completely. The EPYC uses AMD Socket SP3, a server platform. The i5 uses Intel BGA 1744, a soldered mobile socket. The EPYC is a server/workstation part, while the i5 is a mobile part. The EPYC has no integrated graphics, while the i5 includes Iris Xe Graphics 80EU.

Release dates and pricing reflect their market positions. The EPYC 7713P launched on 2021-03-14 with a launch MSRP of $5010. The i5-1345U launched on 2023-01-03 with a launch MSRP of $309. The EPYC's transistor count is 33,200 million, while the i5's is not recorded. The EPYC's die size is 8x 81 mm², while the i5's is not recorded.

The EPYC supports ECC memory, the i5 does not. The EPYC has eight-channel memory, the i5 has dual-channel. The EPYC has 128 PCIe Gen 4 lanes, the i5 has 8. The EPYC's memory bandwidth is 204.8 GB/s, while the i5's is not recorded. The EPYC's L3 cache is 256 MB, the i5's is 12 MB.

The Verdict

The data points to a clear conclusion: these processors serve entirely different markets. The AMD EPYC 7713P is a server and workstation processor for workloads that demand massive multi-core throughput. Its 64 cores, 128 threads, 256 MB of L3 cache, and eight-channel memory make it the choice for virtualization, database workloads, and compute-intensive applications. The Cinebench results, with multi-core deltas ranging from 432.3% to 796.3% over the i5, show a processor that is in a different performance class entirely.

The Intel Core i5-1345U is a mobile processor for laptops and compact systems. Its 10 cores, 12 threads, 15 W TDP, and integrated Iris Xe Graphics make it suitable for general productivity, web browsing, and light content creation. Its Passmark results, including a data compression score of 164005 and a single-thread score of 3415, show a balanced mobile chip. It is not designed to compete with the EPYC in raw compute, and the benchmark data confirms it does not.

Choose the AMD EPYC 7713P if your workloads scale across many cores and you need server-class memory bandwidth, ECC support, and 128 PCIe lanes. Choose the Intel Core i5-1345U if you need a power-efficient mobile processor with integrated graphics for everyday tasks. The benchmark data does not suggest any overlap in their intended use cases.
