The AMD EPYC 7702P and Intel Core i3-1315U occupy opposite ends of the computing spectrum, yet their average benchmark scores place them within 0.7% of each other. This comparison examines a 64-core server processor designed for massive parallelism against a 6-core mobile chip built for efficiency. The data reveals that while the EPYC 7702P dominates every Cinebench test by a wide margin, the Core i3-1315U counters with a suite of Passmark workloads where it demonstrates specialized strengths. The following analysis relies solely on the provided benchmark results and architectural specifications.

FAQ

Q: Which processor has the higher average benchmark score?

A: The AMD EPYC 7702P has an average benchmark score of 15130, while the Intel Core i3-1315U scores 15022. The EPYC leads by 0.7%, a narrow margin that places both in the 69th percentile of all CPUs.

Q: How do the core counts compare between these two processors?

Q: Does the Intel processor have integrated graphics?

A: Yes, the Intel Core i3-1315U includes UHD Graphics 64EU. The AMD EPYC 7702P has no integrated graphics, requiring a discrete GPU for display output.

Q: What is the memory bandwidth difference?

A: The AMD EPYC 7702P supports eight-channel DDR4 memory with a bandwidth of 204.8 GB/s. The Intel Core i3-1315U supports dual-channel DDR4 or DDR5, but its memory bandwidth is not listed in the data.

Q: Which processor was released more recently?

A: The Intel Core i3-1315U was released on 2023-01-03, while the AMD EPYC 7702P was released on 2019-08-06. The Intel part is newer by roughly 3.5 years.

Architecture Differences

The AMD EPYC 7702P is built on Zen 2 architecture under the Rome codename, manufactured on a 7 nm process at TSMC. It packs 3,800 million transistors into a 74 mm² die and uses the AMD Socket SP3. The Intel Core i3-1315U uses Raptor Lake architecture with the Raptor Lake-U codename, fabricated on a 10 nm process at Intel, and mounts on Intel BGA 1744. The EPYC's transistor count and die size are specified; the Intel part lists neither.

Cache hierarchies diverge sharply. The EPYC 7702P offers 96 KB L1 per core, 512 KB L2 per core, and a massive 256 MB shared L3 cache. The Core i3-1315U provides 80 KB L1 per core, 1.25 MB L2 per core, and 10 MB shared L3. The EPYC's L3 cache is 25.6 times larger, a critical factor for server workloads with large working sets.

Memory and I/O capabilities further separate these parts. The EPYC 7702P supports DDR4 across an eight-channel bus with 204.8 GB/s bandwidth and ECC memory. The Core i3-1315U supports both DDR4 and DDR5 on a dual-channel bus, lacks ECC support, and offers PCIe Gen 4 with 8 lanes (CPU only). The EPYC also uses PCIe Gen 4 but does not specify lane count. The Intel part includes integrated UHD Graphics 64EU, a feature absent from the EPYC.

Power and clock behavior differ fundamentally. The EPYC 7702P has a 200 W TDP with a 2000.00 MHz base clock and 3.35 GHz boost. The Core i3-1315U has a 15 W TDP, 1200.00 MHz base clock, and 4.50 GHz boost. The Intel chip boosts 34% higher but draws 92.5% less power. Neither processor has an unlocked multiplier.

Head-to-Head Benchmarks

The AMD EPYC 7702P wins all six head-to-head Cinebench tests, posting remarkably consistent deltas. In Cinebench R15 multicore, the EPYC scores 5272 versus 944 for the Core i3-1315U, a 458.5% advantage. The single-core R15 test shows 744 against 133, a 459.4% delta. Cinebench R20 multicore yields 21969 versus 3937, a 458% difference, while single-core R20 shows 3101 versus 555, a 458.7% gap. Cinebench R23 multicore delivers 52308 versus 9374, a 458% delta, and single-core R23 gives 7384 versus 1323, a 458.1% difference.

These deltas cluster tightly between 458% and 459.4%, indicating the EPYC's advantage scales uniformly across rendering workloads regardless of thread count. The multicore results reflect the EPYC's 64-core design overwhelming the Core i3's 6 cores. The single-core results are more surprising — the EPYC's 3.35 GHz boost clock trails the Core i3's 4.50 GHz, yet the Zen 2 architecture still delivers roughly 4.6 times the performance in these specific tests.

The Passmark suite, available only for the Intel Core i3-1315U, shows its specialized capabilities. The Core i3 scores 126436 in data compression, 7583 in data encryption, 7413 in extended instructions, 41 in find prime numbers, 27012 in floating point math, 37644 in integer math, 11482 in multithread, 706 in physics, 14028 in random string sorting, and 3380 in single-thread tests. These scores are not directly comparable to the EPYC since the AMD part lacks Passmark results in the pack.

The Verdict

The data supports a clear division of purpose. The AMD EPYC 7702P is the overwhelming choice for any workload measured by Cinebench, winning all six tests with deltas exceeding 458%. Its 64-core, 128-thread configuration, combined with 256 MB of L3 cache and eight-channel memory, targets server and workstation environments where parallel rendering and compute density matter most. The 69th percentile ranking and 15130 average score reflect strong overall performance, though the nearest rivals include the Intel Core i3-1315U itself at 0.7% behind.

The Intel Core i3-1315U, despite losing every head-to-head benchmark, matches the EPYC's average score within 0.7% thanks to its Passmark results. Its 15 W TDP, integrated UHD Graphics 64EU, and dual-channel DDR4/DDR5 support position it for mobile and low-power systems. The 4.50 GHz boost clock and 10 MB L3 cache serve single-threaded and burst workloads effectively. Neither processor offers an unlocked multiplier, and both are active production parts.

For buyers, the EPYC 7702P suits rack-mounted servers, virtualization hosts, or compute clusters where the 200 W TDP is acceptable. The Core i3-1315U fits laptops or compact desktops where the 15 W TDP and integrated graphics eliminate the need for a discrete GPU. The EPYC's 2019 release date versus the Core i3's 2023 release date also matters for platform longevity, though the EPYC remains in active production.

Specification Differences

The two processors differ in nearly every measurable specification. The EPYC 7702P has 64 cores and 128 threads; the Core i3-1315U has 6 cores and 8 threads. Base clocks are 2000.00 MHz versus 1200.00 MHz, while boost clocks are 3.35 GHz versus 4.50 GHz. TDP ratings are 200 W versus 15 W. Sockets differ: AMD Socket SP3 versus Intel BGA 1744.

Cache configurations diverge completely. The EPYC provides 96 KB L1 per core, 512 KB L2 per core, and 256 MB shared L3. The Core i3 offers 80 KB L1 per core, 1.25 MB L2 per core, and 10 MB shared L3. Memory support shows DDR4 for the EPYC versus DDR4 and DDR5 for the Core i3. Memory buses are eight-channel versus dual-channel. Memory bandwidth is 204.8 GB/s for the EPYC; the Core i3's bandwidth is not listed. ECC memory is supported only by the EPYC.

PCIe versions match at Gen 4, but the Core i3 specifies 8 lanes (CPU only) while the EPYC does not list lane count. Integrated graphics exist only on the Core i3 as UHD Graphics 64EU. Process nodes are 7 nm for the EPYC and 10 nm for the Core i3. Transistor count and die size are listed only for the EPYC at 3,800 million and 74 mm². The EPYC's launch MSRP is not provided; the Core i3's launch MSRP is $309.

Where Each One Wins

The AMD EPYC 7702P wins in every Cinebench scenario, making it the superior choice for multi-threaded rendering, 3D animation, and video encoding tasks measured by these benchmarks. Its 52308 Cinebench R23 multi-core score and 21969 R20 multi-core score indicate exceptional throughput for heavily parallel workloads. The 256 MB L3 cache and 204.8 GB/s memory bandwidth support data-intensive server applications like database hosting, scientific simulation, and large-scale virtualization. The 458% lead over the Core i3 in every test underscores its dominance in compute-heavy environments.

The Intel Core i3-1315U wins in power efficiency and platform integration. Its 15 W TDP enables fanless or low-noise mobile designs, while the integrated UHD Graphics 64EU removes the need for a separate GPU in basic display tasks. The Passmark results — particularly 126436 in data compression and 37644 in integer math — suggest strengths in file archival, data processing, and general productivity workloads. The 4.50 GHz boost clock provides responsive single-threaded performance for interactive applications. The dual-channel DDR4/DDR5 support offers memory flexibility, and the 2023 release date means a newer platform. For users prioritizing battery life, portability, or integrated graphics, the Core i3-1315U is the practical choice despite losing the Cinebench comparisons.
