AMD EPYC 9654P vs Intel Core i7-13620H Comparison

Head-to-Head Benchmarks

The comparison between the Intel Core i7-13620H and the AMD EPYC 9654P is not a contest in any traditional sense. Across every benchmark in the database, the EPYC 9654P dominates. The head-to-head results show six consecutive wins for the AMD part, with no victories recorded for the Intel mobile chip.

The most extreme gap appears in Cinebench R23 multi-core. The EPYC 9654P scores 98,875, while the i7-13620H manages 15,176. That is a delta of -84.7% from the AMD chip's perspective, meaning the Intel processor delivers only about 15% of the EPYC's multi-threaded performance. The margin is so large that the Intel part's score looks like a rounding error next to the server chip.

Single-core results tell a similar, though less dramatic, story. In Cinebench R23 single-core, the EPYC 9654P posts 13,958 against the i7-13620H's 1,833, a delta of -86.9%. Interestingly, the single-core deficit is even larger in percentage terms than the multi-core deficit, which suggests the AMD chip's Zen 4 cores have a substantial per-thread advantage over the Intel Raptor Lake mobile cores in this workload.

Cinebench R20 shows the same pattern. Multi-core: EPYC 9654P at 41,527 versus i7-13620H at 8,305, a -80% delta. Single-core: EPYC 9654P at 5,862 versus i7-13620H at 1,172, again -80%. The consistency of that 80% deficit across both R20 tests indicates a fundamental throughput gap rather than a workload-specific quirk.

Cinebench R15 repeats the theme. Multi-core: EPYC 9654P at 9,966 versus i7-13620H at 2,281, a -77.1% delta. Single-core: EPYC 9654P at 1,406 versus i7-13620H at 263, a -81.3% delta. Even in the oldest Cinebench version, the EPYC's advantage remains in the same range.

The average benchmark scores in the database reflect this divide, though less dramatically because they incorporate the Intel chip's PassMark results. The i7-13620H has an average benchmark score of 24,911, while the EPYC 9654P sits at 24,465. Both sit at the 77th percentile among all CPUs, and both have nearest rivals from entirely different market segments. The Intel part's closest rivals include the Intel Core i7-11850H (delta -0.1%), the Intel Core 5 210H (delta 0.2%), the AMD Ryzen 5 7500F (delta -0.2%), and the AMD Ryzen 9 5900HX (delta 0.4%). The EPYC's nearest rivals include the Intel Core i5-11600 (delta -0.4%), the AMD Ryzen 5 PRO 6650H (delta 0.4%), the Intel Core i5-12450HX (delta -0.5%), and the Intel Core i7-1360P (delta 0.5%). These rival lists tell you everything about positioning: the mobile chip competes with other mobile and mainstream desktop parts, while the server chip's average is dragged down by workloads that do not scale to 96 cores.

Where Each One Wins

The data does not offer much room for nuance. The EPYC 9654P wins every head-to-head benchmark in the database, across all six Cinebench tests. That includes both multi-core and single-core variants of R15, R20, and R23. There is no test result where the Intel Core i7-13620H comes out ahead.

The Intel chip's wins exist only outside the head-to-head table. In the broader benchmark suite, the i7-13620H shows strengths in PassMark tests that reward its specific feature set. It scores 281,335 in data compression, 80,948 in integer math, 59,762 in floating point math, and 24,192 in multithreaded PassMark. It also delivers 15,568 in data encryption and 17,513 in extended instructions. These are respectable numbers for a mobile processor, and they explain why its average benchmark score (24,911) actually edges out the EPYC's (24,465) despite the Cinebench blowout.

The EPYC 9654P, by contrast, has no PassMark results in the database. Its benchmark portfolio consists entirely of Cinebench and Geekbench results. Beyond the Cinebench head-to-head wins, it posts 22,141 in Geekbench multi-core and 1,981 in Geekbench single-core. The i7-13620H has no Geekbench results, so direct comparison on that test is impossible.

For practical purposes, the use-case split is stark. The EPYC 9654P is built for server and workstation workloads that can consume 96 cores and 192 threads. The i7-13620H is a mobile part with 10 cores and 16 threads, designed for laptops where power and thermals matter more than raw throughput. The Cinebench results show the EPYC at roughly 5.5 to 6.5 times the multi-core performance of the Intel chip, depending on the Cinebench version. That is the difference between rendering a frame in minutes versus hours, or compiling a large codebase in seconds versus minutes.

Architecture Differences

The architectural gap between these two processors is enormous, and it explains the benchmark results better than any single specification.

The Intel Core i7-13620H uses Raptor Lake architecture, specifically the Raptor Lake-H variant. It is built on Intel's 10 nm process node at Intel's own foundry. The chip has 10 cores and 16 threads, with an 80 KB L1 cache per core, a 2 MB L2 cache per core, and 24 MB of shared L3 cache. The memory controller supports both DDR4 and DDR5 in a dual-channel configuration. It does not support ECC memory. The integrated graphics are UHD Graphics 770, and the PCIe implementation is Gen 5 with 8 CPU-only lanes.

The AMD EPYC 9654P uses Zen 4 architecture under the Genoa codename. It is built on TSMC's 5 nm process. The chip packs 96 cores and 192 threads. The cache hierarchy is different in kind: 64 KB L1 per core, 1 MB L2 per core, and a massive 384 MB of shared L3. The memory subsystem is twelve-channel DDR5, with a rated memory bandwidth of 460.8 GB/s. It supports ECC memory. There is no integrated graphics. The PCIe implementation is Gen 5 with 128 CPU-only lanes. The EPYC also reports 78,840 million transistors across 12 separate 72 mm² dies, a detail that highlights its chiplet-based design.

The process node difference alone is significant: 10 nm Intel versus 5 nm TSMC. The EPYC's smaller node allows more transistors in a similar power envelope, though the TDP numbers tell a complex story. The Intel chip is rated at 45 W, while the EPYC is rated at 360 W. That eightfold power difference is part of why the EPYC can sustain such high throughput, but it also means the two chips are not competing for the same socket, chassis, or use case.

The single-core Cinebench results are particularly telling. The EPYC 9654P outperforms the i7-13620H by 81% to 87% in single-threaded tests, despite having a much lower boost clock (3.70 GHz versus 4.90 GHz). This shows that Zen 4's IPC advantage over Raptor Lake in these workloads is substantial. The EPYC's lower clock speed does not hurt it in single-core tests because the architecture is simply more efficient at executing instructions per cycle.

The Verdict

The data makes the choice simple for anyone building around these two very different sockets. If you need server or workstation throughput, the AMD EPYC 9654P is the only option. Its 96 cores, 192 threads, 384 MB of L3 cache, twelve-channel memory, and 128 PCIe Gen 5 lanes are built for workloads that scale across many cores. The Cinebench results show it outperforming the Intel chip by 77% to 87% across every test, with the largest gap in R23 multi-core at 84.7%.

If you need a mobile processor for a laptop, the Intel Core i7-13620H is the only option. It is a 45 W part on a BGA socket, with integrated graphics, support for both DDR4 and DDR5, and a 4.90 GHz boost clock. Its PassMark results show solid performance in data compression, integer math, and floating point math, with strengths that make it a capable mobile workhorse.

The launch MSRP difference, $502 versus $10625, reflects the market positioning, but the choice is not about price. It is about platform. The EPYC requires a Socket SP5 server motherboard, twelve-channel memory, and a cooling solution capable of handling 360 W. The Intel chip requires a laptop motherboard with BGA 1744. No user is cross-shopping these two parts for the same build.

The benchmark database shows both processors sitting at the 77th percentile, which is a reminder that percentile rankings can be misleading when comparing across market segments. The EPYC's average score is dragged down by having only Cinebench and Geekbench results in the database, while the Intel chip benefits from a broader PassMark suite. In the head-to-head tests that directly compare both, the EPYC wins every single one. For anyone who needs the EPYC's capabilities, the Intel chip is not a substitute. For anyone who needs a mobile processor, the EPYC is not a relevant comparison. The verdict is not which chip is better overall, but which chip fits the socket and workload you actually have.
