CPU Comparison

Where Each One Wins

The data presents an unusually uniform picture: across all six Cinebench head-to-head tests, the AMD EPYC 7D12 wins every single round. The margins are consistent at exactly 3.8% in each test, from Cinebench R15 single-core to Cinebench R23 multi-core. That consistency is itself the story, the 7D12 does not merely edge ahead in one workload type; it maintains the same relative advantage whether the benchmark stresses one thread or all available threads.

The AMD EPYC 7F52, despite being the higher-clocked part on paper, never takes a single benchmark win. Its best showing is in single-core workloads, where it still trails by 3.8% (499 vs 518 in Cinebench R15 single-core, 2082 vs 2162 in R20 single-core, 4958 vs 5148 in R23 single-core). The 7F52's higher base clock of 3.50 GHz and boost clock of 3.90 GHz do not translate into a single-core victory against the 7D12's 1.10 GHz base and 3.00 GHz boost. This suggests that architectural efficiency or cache behavior, rather than raw clock speed, drives the 7D12's edge.

Multi-core workloads show the same pattern with larger absolute gaps. In Cinebench R23 multi-core, the 7D12 scores 36465 against the 7F52's 35123, a difference of 1342 points. In Cinebench R15 multi-core, the gap is 135 points (3675 vs 3540). The 7D12's 32 cores and 64 threads, double the 7F52's 16 cores and 32 threads, might seem the obvious explanation, but the consistent 3.8% margin across both single- and multi-core tests points to a per-thread efficiency advantage rather than a raw core-count advantage.

The 7F52's role is better understood through its nearest rivals. It sits at percentile 66 among all CPUs, with an average benchmark score of 10159. Its closest competitor is the Intel Xeon Platinum 8280, which scores 10230, the 7F52 trails by 0.7%. The 7D12 also sits at percentile 66, with an average score of 10547, placing it 3.8% ahead of its closest rival, the Intel Core i7-4790 (10556, delta -0.1%). In practical terms, both EPYC parts land in the same performance tier, but the 7D12 occupies the upper edge of that tier.

The Verdict

The benchmark data supports a clear, if lopsided, conclusion: the AMD EPYC 7D12 is the better performer in every measured scenario. With six wins out of six head-to-head tests and a uniform 3.8% advantage across all Cinebench versions and thread counts, the 7D12 is the default recommendation for anyone comparing these two parts purely on benchmark scores.

The 7F52 is not a weak processor, its average benchmark score of 10159 places it within 3.8% of the 7D12's 10547, and it outperforms several Intel Xeon parts including the Xeon Platinum 8280 (10230, -0.7%) and Xeon Gold 6338N (10347, -1.8%). But in a direct comparison, the data shows no scenario where the 7F52 comes out ahead. Even in single-threaded workloads, where its 3.50 GHz base clock and 3.90 GHz boost clock should give it an edge, the 7D12's 3.00 GHz boost clock wins by 3.8%.

For workloads that scale across cores, the choice is even more straightforward. The 7D12's 32 cores and 64 threads deliver higher multi-core scores across the board, with the largest absolute gap in Cinebench R23 multi-core (36465 vs 35123). The 7F52's 16 cores and 32 threads do not compensate through clock speed in any measured test.

That said, the data does not include power consumption or total cost of ownership metrics. The 7D12 carries an 85 W TDP while the 7F52 is rated at 240 W, but the FACT PACK provides no thermal or efficiency benchmarks to weigh against the performance results. If such factors matter, they would need to be evaluated separately. On pure benchmark performance, the 7D12 wins decisively.

Head-to-Head Benchmarks

The head-to-head results are remarkably consistent, so much so that the deltaPct is identical (3.8%) across all six tests. This uniformity suggests that the performance difference is structural rather than workload-dependent.

Cinebench R15 Multi-Core: The 7D12 scores 3675, the 7F52 scores 3540. The 7D12 leads by 135 points, a 3.8% margin. This test favors the 7D12's higher core count, though the margin is smaller than the core count difference might imply.

Cinebench R15 Single-Core: The 7D12 scores 518, the 7F52 scores 499. The 7D12 leads by 19 points, again 3.8%. This is the most surprising result, the 7F52's clock advantage (3.50 GHz base, 3.90 GHz boost vs 1.10 GHz base, 3.00 GHz boost) does not overcome the 7D12's per-core efficiency.

Cinebench R20 Multi-Core: The 7D12 scores 15315, the 7F52 scores 14751. The gap is 564 points, 3.8%. The 7D12's 32 cores continue to deliver higher throughput in this newer Cinebench version.

Cinebench R20 Single-Core: The 7D12 scores 2162, the 7F52 scores 2082. The 7D12 leads by 80 points, 3.8%. The single-core margin holds steady even as the benchmark generation changes.

Cinebench R23 Multi-Core: The 7D12 scores 36465, the 7F52 scores 35123. The largest absolute gap of the set: 1342 points, still 3.8%. This is the flagship multi-core test, and the 7D12 extends its lead in absolute terms.

Cinebench R23 Single-Core: The 7D12 scores 5148, the 7F52 scores 4958. The 7D12 leads by 190 points, 3.8%. Even in the most modern single-threaded test, the 7D12 holds the same percentage advantage.

The consistency of the 3.8% delta across every test is notable. It implies that the 7D12's advantage is not about core scaling or clock speeds, it is a uniform per-thread efficiency lead. The 7F52's higher clocks (3.50/3.90 GHz) and smaller die (74 mm² vs 4x 74 mm²) do not translate into any benchmark victory.

FAQ

Q: Does the AMD EPYC 7F52 win any benchmark against the 7D12?

Q: Which processor has more cores and threads?

A: The 7D12 has 32 cores and 64 threads. The 7F52 has 16 cores and 32 threads, exactly half of the 7D12's counts.

Architecture Differences

Both processors share the same fundamental architecture: Zen 2, codename Rome, built on a 7 nm process at TSMC. Both use the AMD Socket SP3 and target the server/workstation market segment. Both were released on the same date (2020-04-13) and remain in active production. The similarities end there.

Cores and Threads: The 7D12 doubles the 7F52's core count, 32 cores and 64 threads versus 16 cores and 32 threads. This is the most obvious architectural difference and explains the 7D12's multi-core advantage, though the consistent single-core edge suggests deeper differences.

Clocks: The 7F52 has a significantly higher base clock (3.50 GHz vs 1.10 GHz) and boost clock (3.90 GHz vs 3.00 GHz). Despite this, the 7D12 wins all single-core tests, indicating that clock speed is not the limiting factor.

Thermal Design Power: The 7D12 is rated at 85 W TDP, while the 7F52 is rated at 240 W. This is a substantial difference, though the FACT PACK does not include efficiency benchmarks to interpret it further.

Cache Layout: The two processors use different cache architectures. The 7D12 has 64 KB L1 per core, 512 KB L2 per core, and 32 MB L3 per die, totaling 128 MB L3 across four dies. The 7F52 has 96 KB L1 per core, 512 KB L2 per core, and 256 MB shared L3. The 7F52's larger shared L3 (256 MB vs 128 MB total) does not translate into benchmark wins.

Die Size and Transistors: The 7D12 uses a 4x 74 mm² die configuration with 15,200 million transistors. The 7F52 uses a single 74 mm² die with 3,800 million transistors. The 7D12's four-die design aligns with its higher core count and larger total L3.

PCIe Support: Both support PCIe Gen 4. The 7D12 specifies 128 lanes (CPU only), while the 7F52 lists PCIe Gen 4 without a lane count in the FACT PACK.

Memory: Both support DDR4 with an eight-channel bus and 204.8 GB/s bandwidth, and both have ECC memory support. There is no memory-related differentiation in the data.

Package and Production: Both use the AMD Socket SP3, are in active production, and have locked multipliers (not unlocked). The 7D12's part number is 100-000000044; the 7F52's is 100-000000140100-000000140WOF.

The architectural story is one of a high-core-count, low-clock, multi-die part (7D12) versus a low-core-count, high-clock, single-die part (7F52). The benchmarks show that, in Cinebench workloads, the 7D12's configuration is superior across the board. The 7F52's larger shared L3 cache and higher clocks are not enough to overcome the 7D12's per-thread efficiency, which the data reveals as a consistent 3.8% advantage in every test.
