AMD EPYC 7J13 vs Intel Core i3-1220P Comparison

The Intel Core i3-1220P and AMD EPYC 7J13 occupy opposite ends of the computing spectrum, and the benchmark data reflects this starkly. The i3-1220P is a 10-core mobile processor designed for thin-and-light laptops, while the EPYC 7J13 is a 64-core server monster built for heavy virtualized and enterprise workloads. In every single benchmark recorded, the EPYC 7J13 wins decisively, often by margins exceeding 80%. However, the i3-1220P holds its own in the broader context of all CPUs, with both processors landing at the 74th percentile. The real question isn't which is faster — it's which fits the intended use case.

The Verdict

Based strictly on the data, the AMD EPYC 7J13 is the undisputed performance king. It wins all six head-to-head benchmarks, with the EPYC delivering scores that are roughly 5.4 times higher than the i3-1220P in multi-core tests. For instance, in Cinebench R23 multi-core, the EPYC scores 72,068 versus the i3's 13,314, a delta of -81.5% for the Intel part. If raw compute throughput is the only metric that matters, the EPYC 7J13 is the only choice.

However, the Intel Core i3-1220P is not without merit. Its average benchmark score of 21,066 is nearly identical to the EPYC's 20,845, and both sit at the 74th percentile of all CPUs. This is remarkable for a 28-watt mobile chip. The i3-1220P's nearest rivals include the AMD Ryzen 5 5600G and Intel Core Ultra 7 256V, with deltas of -0.1% and -0.2% respectively, meaning it trades blows with those established mid-range parts. For a mobile user, the i3-1220P offers a balanced package with integrated graphics and modern memory support.

The verdict is simple: choose the EPYC 7J13 for server racks, multi-threaded rendering farms, and data-center workloads. Choose the i3-1220P for a laptop that needs solid everyday performance, efficient power use, and a modern feature set. The data does not support using the EPYC in a mobile context (it has no integrated graphics and a 280W TDP), nor does it support using the i3 for heavy server duty.

Architecture Differences

The two chips come from completely different design philosophies. The Intel Core i3-1220P uses the Alder Lake architecture on a 10 nm process fabricated by Intel, codenamed Alder Lake-P. It belongs to the Core i3 generation. In contrast, the AMD EPYC 7J13 is built on the Zen 3 architecture using a 7 nm process from TSMC, with the codename Milan.

The EPYC's construction is fundamentally different in scale. It packs 33,200 million transistors across 8 separate chiplets, each measuring 81 mm², totaling a massive die area. The Intel chip's transistor count and die size are not listed, but its architecture is monolithic by design. The EPYC features a shared L3 cache of 256 MB, while the i3 has a much smaller 12 MB shared L3 cache. Per-core cache also differs: the i3 has 80 KB L1 and 1.25 MB L2 per core, while the EPYC has 64 KB L1 and 512 KB L2 per core.

Memory architecture is another major divider. The EPYC supports eight-channel DDR4 with a memory bandwidth of 204.8 GB/s and ECC memory, which is critical for data integrity in servers. The i3-1220P supports dual-channel DDR4 and DDR5, but lacks ECC. The EPYC also provides 128 PCIe Gen 4 lanes versus the i3's 20 lanes, enabling massive I/O expansion. The i3 integrates UHD Graphics 64EU, a feature absent from the EPYC, as server processors typically rely on discrete or baseboard management controllers.

Specification Differences

The core specs highlight the gulf between these processors. The Intel Core i3-1220P has 10 cores and 12 threads, with a base clock of 1.50 GHz and a boost clock of 4.40 GHz. Its TDP is just 28 watts. The AMD EPYC 7J13 has 64 cores and 128 threads, with a base clock of 2.55 GHz and a boost clock of 3.50 GHz. Its TDP is 280 watts — exactly ten times the Intel part.

The sockets are incompatible: the i3 uses Intel BGA 1744, while the EPYC uses AMD Socket SP3. The Intel chip has a release date of February 22, 2022, whereas the EPYC's release date is not provided in the data. Both processors are currently marked as "Active" in production status. Neither has an unlocked multiplier. The part numbers are SRLFY for the Intel and 100-000000346 for the AMD.

The Intel processor supports DDR4 and DDR5 memory in dual-channel mode, while the EPYC is limited to DDR4 but in eight-channel configuration. The EPYC has a listed memory bandwidth of 204.8 GB/s; the Intel chip's bandwidth is not specified. ECC memory is supported only on the EPYC. PCIe capabilities are also vastly different: 20 lanes on the i3 versus 128 lanes on the EPYC, both Gen 4.

Head-to-Head Benchmarks

The head-to-head data is one-sided. The AMD EPYC 7J13 wins all six benchmarks, with the Intel Core i3-1220P trailing by a consistent -81.5% in most tests. This consistency suggests the performance gap is not a fluke but a structural advantage in core count and memory bandwidth.

In Cinebench R15 multi-core, the EPYC scores 7,264 versus the i3's 1,341, a delta of -81.5%. Single-core R15 shows the EPYC at 1,025 versus 189, also -81.5%. Moving to Cinebench R20, multi-core results are 30,268 for AMD and 5,591 for Intel, again -81.5%. Single-core R20 shows 4,273 against 789, a -81.5% delta. The pattern holds in Cinebench R23: multi-core is 72,068 versus 13,314, and single-core is 10,174 versus 1,879, both at -81.5%.

These deltas mean the EPYC is roughly 5.4 times faster in every Cinebench test. For a mobile chip to be beaten by that margin is expected, but the absolute scores are informative. The i3-1220P's single-core R23 score of 1,879 is respectable for a low-power part, while the EPYC's 10,174 is elite. In multi-core workloads, the EPYC's 64 cores simply overwhelm the i3's 10 cores. The EPYC's advantage in single-core tests, despite a lower boost clock (3.50 GHz versus 4.40 GHz), indicates the Zen 3 architecture and higher base clock deliver superior per-thread performance.

Where Each One Wins

The AMD EPYC 7J13 wins in every benchmark category recorded. It is the clear choice for multi-threaded rendering, scientific computing, database serving, and any workload that can utilize 128 threads. Its 256 MB L3 cache and 204.8 GB/s memory bandwidth make it ideal for large in-memory datasets. The eight-channel memory controller and 128 PCIe lanes support massive storage arrays and high-speed networking. For server virtualization, the EPYC's core count allows dozens of concurrent virtual machines without contention.

The Intel Core i3-1220P wins in scenarios not captured by the benchmark suite. Its 28-watt TDP makes it suitable for fanless or low-noise laptops, where the EPYC's 280-watt TDP is impossible. The integrated UHD Graphics 64EU provides display output without a discrete GPU, a feature the EPYC lacks entirely. The i3 supports DDR5 memory, which is a modern upgrade path for mobile platforms. Its small footprint and BGA 1744 socket are designed for ultrabooks and compact devices. While the EPYC dominates raw performance, the i3 wins on portability, power efficiency, and integrated features.

In the broader benchmark landscape, both CPUs score nearly identically on average — 21,066 for the i3 and 20,845 for the EPYC — which reflects the diversity of workloads tested. The i3's PassMark scores include data compression at 180,528 and integer math at 53,507, indicating strong general-purpose performance for a mobile chip. The EPYC lacks PassMark results in the data, so its average is drawn solely from Cinebench scores. For a builder choosing between these, the decision hinges on the physical platform: a laptop demands the i3, a server demands the EPYC. Neither can substitute for the other.
