AMD EPYC 7262 vs Intel Core i9-10900KF Comparison

The Intel Core i9-10900KF and AMD EPYC 7262 target different segments: the former is a desktop processor with 10 cores and 20 threads, the latter a server/workstation chip with 8 cores and 16 threads. In the recorded head-to-head benchmarks, the Intel part wins all six Cinebench tests, each by a 6.8% margin. The EPYC counters with platform features: eight-channel DDR4 memory, 128 PCIe Gen4 lanes, and ECC support. These are not competing on the same battlefield, but the data allows a clear comparison of compute and platform capabilities.

Where Each One Wins

The Intel Core i9-10900KF wins every head-to-head benchmark recorded in the database. All six Cinebench tests, covering R15, R20, and R23 in both single-core and multi-core modes, show the Intel part ahead by exactly 6.8%. That includes a multi-core R23 score of 18867 against 17662, and a single-core R23 score of 2663 against 2493. The Intel part also has a higher boost clock (5.30 GHz vs 3.40 GHz) and a higher base clock (3.70 GHz vs 3.20 GHz), which explains its consistent compute advantage. The EPYC 7262 has zero wins in the head-to-head set.

The AMD EPYC 7262 wins on platform capabilities, not on benchmark scores. It offers eight-channel memory with 204.8 GB/s bandwidth, compared to the Intel's dual-channel 46.9 GB/s. It provides 128 PCIe Gen4 lanes, while the Intel has 16 Gen3 lanes. It supports ECC memory, which the Intel does not. Its total L3 cache is 128 MB, versus 20 MB on the Intel. These features are not measured in the Cinebench tests, but they are decisive for server and workstation workloads that rely on memory throughput, I/O expansion, and data integrity.

Architecture Differences

The two processors are built on fundamentally different architectures. The Intel uses a 14 nm process from Intel's own foundry, while the AMD uses a 7 nm process from TSMC. The AMD chip integrates 15,200 million transistors across four dies, each 74 mm², whereas the Intel's transistor count and die size are not listed. The cache hierarchy differs: both have 64 KB L1 per core, but the Intel has 256 KB L2 per core and 20 MB shared L3, while the AMD has 512 KB L2 per core and 32 MB L3 per die, totaling 128 MB.

Memory support is a major split. Both use DDR4, but the Intel runs dual-channel with 46.9 GB/s bandwidth and no ECC, while the AMD runs eight-channel with 204.8 GB/s and ECC enabled. PCIe connectivity also diverges: the Intel provides 16 Gen3 lanes, the AMD provides 128 Gen4 lanes. The sockets are incompatible: Intel Socket 1200 for the i9, AMD Socket SP3 for the EPYC. The Intel has an unlocked multiplier, the AMD is locked. The Intel is a desktop part, the AMD is a server/workstation part. The Intel is end-of-life, the AMD is active. Release dates differ: the Intel launched on 2020-04-29, the AMD on 2019-08-06. The part numbers are SRH92 for Intel and 100-000000041 for AMD.

The Verdict

The data shows a clear compute winner: the Intel Core i9-10900KF outperforms the AMD EPYC 7262 in every recorded benchmark, with a uniform 6.8% lead. It has more cores (10 vs 8), more threads (20 vs 16), and higher clock speeds. For any workload that is measured by Cinebench, the Intel part is the faster choice.

The AMD EPYC 7262, however, is not designed for that kind of comparison. Its strengths lie in server infrastructure: ECC memory, eight-channel memory bandwidth of 204.8 GB/s, 128 PCIe Gen4 lanes, and a 128 MB L3 cache. It is also still in active production, while the Intel is end-of-life. The launch MSRP for the Intel is $509, and for the AMD is $575. The choice depends on the platform: a desktop builder who prioritizes raw compute should pick the Intel; a server or workstation integrator who needs memory capacity, I/O expansion, and error correction should pick the AMD. The benchmark results do not favor the AMD in compute, but the platform features are not captured in those tests.

FAQ

Q: Which CPU has higher single-core performance?

Head-to-Head Benchmarks

All six head-to-head tests are from the Cinebench suite. The Intel Core i9-10900KF wins each with a 6.8% delta. In Cinebench R15 multi-core, the Intel scores 1901 against 1780. In R15 single-core, it scores 268 against 251. In R20 multi-core, 7924 against 7418. In R20 single-core, 1118 against 1047. In R23 multi-core, 18867 against 17662. In R23 single-core, 2663 against 2493. The consistent 6.8% margin across both single and multi-threaded tests indicates a uniform performance advantage, likely driven by the higher clock speeds and additional cores. The head-to-head list does not include 3DMark or Geekbench scores for the EPYC, so those cannot be compared. The Intel also has its own 3DMark and Geekbench results, but without corresponding EPYC scores, they are not part of the head-to-head analysis.

The two CPUs share the same L1 cache size (64 KB per core), the same memory type (DDR4), and both lack integrated graphics. Their percentile ranking among all CPUs is identical at 60. The differences in cache, memory, PCIe, and production status define their respective roles: the Intel is a high-clock desktop part, the AMD is a high-bandwidth server part.
