AMD EPYC 7713 vs Intel Core i5-11600KF Comparison

Head-to-Head Benchmarks

The recorded data paints a remarkably one-sided picture. Across all six shared Cinebench tests, the AMD EPYC 7713 wins every single matchup, and the margin is consistently enormous. In Cinebench R23 multi-core, the EPYC 7713 scores 70,401 while the Core i5-11600KF manages only 16,503, a delta of 326.6%. That is more than four times the multi-threaded output of the Intel part.

The single-core results tell an even more surprising story. One might expect a 4.90 GHz boost clock on the Intel chip to dominate a 3.68 GHz server part, but the data shows otherwise. In Cinebench R23 single-core, the EPYC 7713 scores 9,939 against 2,329 for the Core i5-11600KF, a 326.7% advantage. The same pattern repeats across R15 and R20: single-core deltas of 327.8% and 326.8% respectively, both favoring the AMD processor. This suggests the EPYC's architecture delivers far more instructions per clock in these workloads than the raw clock-speed difference would imply.

Multi-core results are equally lopsided. Cinebench R15 multi-core shows 7,096 versus 1,663 (326.7% delta), R20 shows 29,568 versus 6,931 (326.6% delta), and R23 shows the aforementioned 70,401 versus 16,503. The consistency of these deltas, all hovering around 326-327%, indicates a stable performance ratio that scales uniformly across benchmark generations. The wins tally confirms the sweep: 6 wins for AMD, 0 for Intel.

What the head-to-head data does not include is any 3DMark or PassMark comparison, since those tests only appear in the Intel item's benchmark list. The EPYC 7713's benchmark list contains only Cinebench tests, while the Core i5-11600KF has a broader suite. This means the recorded comparison is limited to rendering workloads, and within that scope, the EPYC 7713 is categorically dominant.

Architecture Differences

The two processors occupy completely different design philosophies. The AMD EPYC 7713 is built on TSMC's 7 nm process node, packing 64 cores and 128 threads into a Zen 3 architecture with the codename Milan. The Intel Core i5-11600KF uses Intel's 14 nm process with 6 cores and 12 threads on the Rocket Lake architecture. The transistor counts differ dramatically: the EPYC integrates 33,200 million transistors across an 8x 81 mm² die configuration, while the Core i5-11600KF uses a single 276 mm² die with no transistor count recorded in the database.

Cache hierarchies diverge substantially. The EPYC 7713 allocates 64 KB of L1 per core, 512 KB of L2 per core, and a massive 256 MB of shared L3 cache. The Core i5-11600KF has 80 KB of L1 per core, 512 KB of L2 per core, but only 12 MB of shared L3. For the EPYC, that 256 MB L3 is a defining feature for server workloads that repeatedly access large datasets. For the Intel part, the 12 MB L3 is modest by comparison, though its larger per-core L1 (80 KB versus 64 KB) suggests attention to single-thread latency.

Memory architecture reinforces the server-versus-desktop split. The EPYC 7713 supports DDR4 across an eight-channel memory bus with 204.8 GB/s of bandwidth and full ECC support. The Core i5-11600KF also supports DDR4 but only on a dual-channel bus, delivering 51.2 GB/s and no ECC capability. That is a fourfold difference in theoretical memory bandwidth, which matters heavily for multi-threaded server workloads.

PCIe connectivity follows the same pattern. The EPYC 7713 provides Gen 4 with 128 lanes from the CPU, while the Core i5-11600KF offers Gen 4 with only 20 lanes. Neither has integrated graphics. The EPYC targets the server/workstation segment with an active production status, while the Intel part is a desktop processor now marked end-of-life. The EPYC also has a locked multiplier, whereas the Core i5-11600KF is multiplier-unlocked for overclocking.

Specification Differences

The two parts differ in nearly every measurable specification. Core count: 64 versus 6. Thread count: 128 versus 12. Base clock: 2000.00 MHz versus 3900.00 MHz. Boost clock: 3.68 GHz versus 4.90 GHz. TDP: 225 watts versus 125 watts. Socket: AMD Socket SP3 versus Intel Socket 1200. Process node: 7 nm (TSMC) versus 14 nm (Intel). Die size: 8x 81 mm² versus 276 mm². L1 cache: 64 KB per core versus 80 KB per core. L2 cache: 512 KB per core on both. L3 cache: 256 MB shared versus 12 MB shared. Memory bus: eight-channel versus dual-channel. Memory bandwidth: 204.8 GB/s versus 51.2 GB/s. ECC: supported versus not supported. PCIe lanes: 128 Gen 4 versus 20 Gen 4. Market segment: server/workstation versus desktop. Production status: active versus end-of-life. Multiplier: locked versus unlocked.

The release dates are nearly identical: March 14, 2021 for the EPYC and March 15, 2021 for the Core i5. The launch MSRP differs sharply, but the database records these as separate figures without implying any judgment about relative value.

Where Each One Wins

The EPYC 7713 wins every recorded head-to-head benchmark, so its victory domain is unambiguous. In rendering workloads, which is what Cinebench measures, the EPYC 7713 delivers roughly 326% more performance across the board. This makes it the clear choice for any workload that scales with core count and cache capacity: multi-threaded rendering, scientific computing, database serving, and virtualization. The 256 MB L3 cache and 204.8 GB/s memory bandwidth position it for data-heavy server tasks where working sets exceed what smaller caches can hold.

The Core i5-11600KF does have advantages in the recorded data, though not in the shared benchmarks. Its PassMark results show strengths in specific single-threaded tasks: a PassMark single-thread score of 3,327, a floating point math score of 38,129, and an integer math score of 64,195. Its 3DMark results (single thread 962, 2 threads 1,861, 4 threads 3,492, 8 threads 5,238, max threads 6,240) indicate balanced scaling up to 8 threads. The unlocked multiplier also allows overclocking, which the EPYC does not permit. For desktop users who prioritize per-core latency, gaming responsiveness, or price-sensitive builds, the Core i5-11600KF offers a lighter-weight platform with a 125 watt TDP versus 225 watts.

The EPYC's 74th percentile versus the Core i5's 73rd percentile shows they sit near each other in the overall CPU distribution, but that percentile ranking aggregates different benchmark suites. The EPYC's average score of 20,363 edges out the Core i5's 19,723, a small gap that reflects the EPYC's narrow Cinebench-only benchmark list versus the Intel part's broader test coverage.

The Verdict

The data supports a straightforward conclusion: the AMD EPYC 7713 dominates the Intel Core i5-11600KF in every direct comparison recorded in the database. Six out of six head-to-head benchmarks go to the EPYC, with deltas consistently around 326-327%. This is not a marginal win; it is a categorical sweep.

The EPYC 7713 is the appropriate choice for server and workstation deployments where multi-threaded rendering performance, massive L3 cache (256 MB), eight-channel memory bandwidth (204.8 GB/s), ECC support, and 128 PCIe Gen 4 lanes matter. Its active production status and 64-core, 128-thread configuration make it a serious compute platform for heavy parallel workloads. The 74th percentile ranking among all CPUs reflects that its Cinebench scores are strong, though its benchmark list is limited to rendering tests.

The Core i5-11600KF serves a different purpose. As a desktop part with 6 cores, 12 threads, a 4.90 GHz boost clock, and an unlocked multiplier, it offers per-thread flexibility and a broader recorded benchmark suite. Its PassMark scores show competence in integer math (64,195), floating point math (38,129), and data compression (242,730). Its 73rd percentile ranking comes from a more diverse set of tests. For a desktop user who wants a modern Intel platform with overclocking headroom, the Core i5-11600KF is a reasonable part, but the head-to-head data shows it cannot compete with the EPYC 7713 in rendering workloads.

The verdict for buyers is simple: choose the EPYC 7713 if the workload involves heavy multi-threading, large datasets, or server-class memory and I/O requirements. Choose the Core i5-11600KF if the workload is desktop-oriented, latency-sensitive, or benefits from overclocking. The benchmark data does not support any scenario where the Core i5-11600KF outperforms the EPYC 7713 in a direct comparison, but the two parts are aimed at entirely different market segments, and the Intel part's unlocked multiplier and lower TDP may suit certain desktop use cases.
