AMD EPYC 9454P vs Intel Core i5-11600KF Comparison

Head-to-Head Benchmarks

The benchmark data records eight head-to-head comparisons between the Intel Core i5-11600KF and the AMD EPYC 9454P, and the results are decisively one-sided. The AMD EPYC 9454P wins all eight tests, though the margins vary dramatically depending on the workload type.

In multi-core rendering tests, the EPYC 9454P delivers overwhelming advantages. In Cinebench R15 multi-core, the EPYC scores 8214 against the Core i5's 1663, a delta of -79.8% from the Intel part's perspective. The same pattern appears in Cinebench R20 multi-core, where the EPYC posts 34226 versus 6931 (-79.7%), and in Cinebench R23 multi-core, where the EPYC reaches 81492 compared to the Intel's 16503 (-79.7%). These are not incremental gains; the EPYC is consistently delivering roughly five times the multi-core performance in these rendering workloads.

The single-core Cinebench results tell a similar story, albeit with a different underlying cause. In Cinebench R15 single-core, the EPYC scores 1159 against 234 (-79.8%). In R20 single-core, it posts 4831 versus 978 (-79.8%). In R23 single-core, the gap narrows slightly in percentage terms to -79.8% as well, with scores of 11504 and 2329 respectively. The consistency of that -79.8% delta across all three Cinebench single-core tests is striking, suggesting a fixed ratio in the scoring methodology rather than workload-specific variation.

Geekbench results show a more nuanced picture. In Geekbench multi-core, the EPYC 9454P scores 19941 against the Core i5's 8688, a delta of -56.4%. That margin, while still large, is considerably smaller than the Cinebench multi-core gap, indicating that Geekbench's multi-core workload does not scale with the EPYC's 48 cores as effectively as Cinebench does. In Geekbench single-core, the gap nearly disappears: the EPYC scores 2011 versus 1904, a delta of only -5.3%. This is the closest result in the entire head-to-head set, and it shows that in lightly threaded integer workloads, the two processors are nearly comparable despite their vastly different architectures and core counts.

Looking at the broader database context, the Intel Core i5-11600KF holds a percentile rank of 73 among all CPUs, while the AMD EPYC 9454P sits at percentile 74. Their average benchmark scores are 19723 for the Intel part and 20422 for the AMD part, a modest overall difference of about 3.5%. The nearest rivals for the Intel part include the Intel Core i5-12500 (19668, delta 0.3%), the Intel Core i5-11600K (19786, delta -0.3%), the AMD Ryzen AI 5 430 (19617, delta 0.5%), and the AMD Ryzen 5 5500 (19593, delta 0.7%).

Architecture Differences

The two processors come from fundamentally different design philosophies. The Intel Core i5-11600KF is built on Rocket Lake architecture, which is manufactured on a 14 nm process at Intel's own foundry. It has 6 cores and 12 threads, with a die size of 276 mm². The AMD EPYC 9454P uses Zen 4 architecture, codenamed Genoa, manufactured on a 5 nm process at TSMC. It packs 48 cores and 96 threads across a complex of 8 chiplets, each 72 mm² in size, for a total transistor count of 52,560 million.

Cache hierarchies differ substantially. The Intel part provides 80 KB of L1 cache per core, 512 KB of L2 per core, and 12 MB of shared L3 cache. The AMD EPYC offers 64 KB of L1 per core, 1 MB of L2 per core, and 256 MB of shared L3 cache. The EPYC's L3 cache is more than twenty times larger in aggregate, which matters for workloads with large working sets that benefit from fast on-die storage.

Memory architecture is another major divergence. The Intel Core i5-11600KF supports DDR4 memory over a dual-channel bus, with a peak memory bandwidth of 51.2 GB/s. The EPYC 9454P supports DDR5 over a twelve-channel bus, delivering 460.8 GB/s of memory bandwidth. That is roughly nine times the memory bandwidth of the Intel part, which directly benefits server workloads that stream large datasets. The EPYC also supports ECC memory, while the Intel part does not.

PCIe connectivity differs as well. The Intel processor provides Gen 4 with 20 CPU lanes. The EPYC provides Gen 5 with 128 CPU lanes, a substantial increase in both generation and lane count for expansion and I/O intensive scenarios.

The Intel Core i5-11600KF has an unlocked multiplier, allowing overclocking, while the EPYC 9454P does not. The Intel part is marked as end-of-life in production status, whereas the EPYC is listed as active. The Intel processor targets the desktop market segment; the EPYC targets server and workstation use.

Multiplier unlocked: true for Intel, false for AMD. Market segment: desktop versus server/workstation. Production status: end-of-life versus active.

The Verdict

The recorded data paints a clear picture. The AMD EPYC 9454P dominates the Intel Core i5-11600KF in every head-to-head benchmark, with particularly extreme margins in multi-core rendering workloads. The EPYC's 48 cores and 96 threads simply overwhelm the Intel part's 6 cores and 12 threads in any workload that can use parallel execution. The Cinebench results, with deltas around -79.7% to -79.8% across both single-core and multi-core variants, indicate that the EPYC's architectural advantages extend even into single-threaded scenarios in that specific benchmark suite.

The Geekbench single-core result, where the EPYC leads by only -5.3%, is the one data point that suggests parity in lightly threaded integer work. If the workload is primarily single-threaded integer operations, the two processors are much closer. But the overall weight of evidence favors the EPYC for any compute-heavy task.

For the Intel Core i5-11600KF, the data supports a clear positioning: it is a desktop processor for users who need modest multi-core capability with a high boost clock of 4.90 GHz and an unlocked multiplier. It is end-of-life, so it is not a forward-looking purchase. Its 73rd percentile ranking and average score of 19723 place it in the same aggregate tier as the EPYC's 74th percentile and 20422 average, but that similarity is misleading given the head-to-head deltas.

The EPYC 9454P is the choice for server and workstation workloads that demand maximum core counts, memory bandwidth, and PCIe connectivity. Its twelve-channel DDR5 memory interface and 460.8 GB/s bandwidth, combined with 128 Gen 5 PCIe lanes, make it suited for data-heavy and I/O intensive environments. The ECC memory support is another point in its favor for reliability-sensitive deployments.

Where Each One Wins

The AMD EPYC 9454P wins in rendering workloads. The Cinebench R23 multi-core score of 81492 against 16503 is the largest absolute gap in the data, and the R20 and R15 multi-core results follow the same pattern. Any workload that scales across many cores will favor the EPYC heavily.

The EPYC also wins in memory bandwidth dependent tasks. With 460.8 GB/s against 51.2 GB/s, the EPYC has roughly nine times the memory bandwidth. The Intel part's dual-channel DDR4 bus cannot compete in scenarios that stream large amounts of data.

The EPYC wins in server I/O scenarios. Its 128 Gen 5 PCIe lanes dwarf the Intel part's 20 Gen 4 lanes, and its twelve-channel memory bus supports far more DIMMs and capacity.

The Intel Core i5-11600KF does not win any of the eight recorded head-to-head benchmarks. Its one point of relative strength is the Geekbench single-core test, where it trails by only -5.3% (1904 versus 2011). For users constrained to a desktop platform with an Intel Socket 1200 motherboard and DDR4 memory, the Intel part offers a 4.90 GHz boost clock and an unlocked multiplier for overclocking, along with a launch MSRP of $237. Its end-of-life status means it is a legacy option rather than a current recommendation.

The EPYC 9454P is the clear performance leader in the recorded data. The only scenario where the Intel part appears competitive is a narrow band of single-threaded integer performance, and even there, the EPYC still holds the edge. The verdict from the measurements is unambiguous: the EPYC 9454P is the superior processor across nearly every metric, with the Intel Core i5-11600KF remaining relevant only in legacy desktop builds or workloads that cannot utilize the EPYC's massive parallel resources.
