AMD Ryzen Threadripper 3960X vs Intel Xeon Gold 6330 Comparison

Head-to-Head Benchmarks

The head-to-head data between the AMD Ryzen Threadripper 3960X and the Intel Xeon Gold 6330 is decisive in every recorded test. Across six Cinebench workloads, the Threadripper 3960X wins all six, with the Xeon Gold 6330 failing to claim a single victory. The margins are remarkably consistent, clustering tightly around the 50% advantage mark in every single test.

Starting with multi-threaded workloads, the gap is substantial. In Cinebench R15 multicore, the Threadripper 3960X scores 4692 against the Xeon Gold 6330's 3115, a 50.6% advantage. The R20 multicore test shows a similar story: 19553 versus 12980, again a 50.6% delta. The R23 multicore result follows the same pattern, with the AMD chip scoring 46557 compared to Intel's 30906, another 50.6% lead. These are not narrow wins; they represent a roughly half-again performance advantage in rendering and compute-heavy multi-core tasks.

The single-core results are even more lopsided in percentage terms. Cinebench R15 single-core sees the Threadripper 3960X at 662 versus 439 for the Xeon Gold 6330, a 50.8% delta. R20 single-core shows 2760 against 1832, a 50.7% lead. R23 single-core completes the sweep with 6572 versus 4363, a 50.6% margin. While the percentage deltas are nearly identical to the multi-core results, the absolute differences are smaller, which is expected given the lower single-thread scores. Still, the consistency of the 50.6% to 50.8% range across all six tests indicates a fundamental performance gap rather than a workload-specific artifact.

It is importantly the Xeon Gold 6330 has more cores (28 versus 24) and more threads (56 versus 48), yet it trails decisively in every benchmark. This suggests that per-core efficiency and clock speed play a dominant role in these Cinebench workloads. The Threadripper 3960X's higher boost clock of 4.50 GHz versus 3.10 GHz for the Xeon is a clear factor. The AMD processor also holds an advantage in the overall average benchmark score: 9284 versus 8939 for the Intel chip, a difference of roughly 3.9% when looking at the aggregate metric.

When placed against their nearest rivals in the database, both CPUs sit at the 65th percentile among all CPUs. The Threadripper 3960X's closest competitor is the Intel Xeon Platinum 8280M with an average score of 9260, a mere 0.3% delta. The Xeon Gold 6330's nearest rival is the Intel Core i7-8650U at 8932, a 0.1% delta. These comparisons show that while the two CPUs are in the same percentile tier, the AMD part is positioned higher within that tier, while the Intel part sits near the lower boundary of its comparable group.

The Verdict

The data points to a single conclusion: the AMD Ryzen Threadripper 3960X is the superior processor in every measured workload. With six wins out of six head-to-head benchmarks and a consistent 50.6% to 50.8% advantage across both single-core and multi-core Cinebench tests, there is no ambiguity. The Threadripper 3960X delivers roughly 50% higher performance in rendering workloads, which are representative of many professional content creation and simulation tasks.

The Intel Xeon Gold 6330, despite having more cores and threads, cannot overcome the clock speed deficit and architectural efficiency gap. Its base clock of 2000.00 MHz and boost clock of 3.10 GHz are far below the Threadripper 3960X's 3.80 GHz base and 4.50 GHz boost. This clock advantage, combined with the Zen 2 architecture's strong instruction-per-clock efficiency, explains the consistent margin.

Who should pick which? From the recorded data alone, the AMD Ryzen Threadripper 3960X is the choice for anyone prioritizing raw Cinebench performance, whether single-threaded or multi-threaded. The Intel Xeon Gold 6330, on the other hand, offers features that the AMD part lacks: ECC memory support, eight-channel memory bus, and a higher memory bandwidth of 204.8 GB/s versus 102.4 GB/s. For workloads that depend on memory bandwidth or error-correcting memory, the Xeon may still be relevant, but for compute throughput as measured here, it is not competitive.

Specification Differences

The two processors differ across nearly every major specification. The AMD Ryzen Threadripper 3960X is a desktop part with 24 cores and 48 threads, while the Intel Xeon Gold 6330 is a server/workstation part with 28 cores and 56 threads. Clock speeds diverge sharply: the AMD chip has a base clock of 3.80 GHz and a boost clock of 4.50 GHz, whereas the Intel chip has a base clock of 2000.00 MHz and a boost clock of 3.10 GHz.

The thermal design power (TDP) also differs, with the AMD part rated at 280 watts and the Intel part at 205 watts. Sockets are incompatible: the AMD uses AMD Socket TRX4, while the Intel uses Intel Socket 4189. The AMD processor has an unlocked multiplier, while the Intel part is locked. The AMD chip was released on 2019-11-24, and the Intel chip on 2021-04-05.

The launch MSRP for the AMD Ryzen Threadripper 3960X is $1399. The Intel Xeon Gold 6330 has no recorded launch MSRP in the database.

Memory support differs in channel count: the AMD part uses quad-channel DDR4, while the Intel part uses eight-channel DDR4. Consequently, the Intel part has double the memory bandwidth: 204.8 GB/s versus 102.4 GB/s. The AMD part does not support ECC memory; the Intel part does. PCIe generation is the same (Gen 4), but the Intel part specifies 64 lanes (CPU only), while the AMD part does not specify a lane count.

Cache configurations are also distinct. Both have 64 KB of L1 per core. The L2 cache is 512 KB per core for AMD and 1 MB per core for Intel. The L3 cache is a major difference: the AMD part has 128 MB, while the Intel part has 42 MB (shared).

Architecture Differences

The AMD Ryzen Threadripper 3960X is built on the Zen 2 architecture, codenamed Castle Peak, and belongs to the Ryzen Threadripper generation. It uses a 7 nm process node manufactured by TSMC. The die consists of 4x 74 mm² chiplets, with 15,200 million transistors. The Intel Xeon Gold 6330 uses the Ice Lake architecture, codenamed Ice Lake-SP, part of the Xeon Gold generation. It is built on a 10 nm process node by Intel, with no recorded transistor count or die size.

The cache hierarchy reflects the architectural differences. The AMD part has a massive 128 MB of L3 cache, which is shared across the chiplet design. The Intel part has 42 MB of shared L3 cache, which is smaller but paired with a larger 1 MB per-core L2 cache compared to AMD's 512 KB per-core. Both have 64 KB of L1 per core.

The AMD processor integrates no graphics, and neither does the Intel part. The market segments differ: the AMD is classified as Desktop, while the Intel is Server/Workstation. The production status for both is Active. The AMD part number is 100-000000010100-100000010WOF; the Intel part number is SRKHMCD8068904572101.

Where Each One Wins

Based strictly on benchmark results, the AMD Ryzen Threadripper 3960X wins in every Cinebench workload recorded. This includes both single-core and multi-core tests across R15, R20, and R23 versions. For applications that are heavily threaded, such as 3D rendering, video encoding, or scientific simulation, the AMD part delivers roughly 50% higher throughput. For single-threaded tasks like legacy software, scripting, or lightly threaded applications, the AMD part also leads by a similar margin.

The Intel Xeon Gold 6330 does not win any recorded benchmarks, but it has advantages in non-benchmark specifications. It offers ECC memory support, which is critical for data integrity in server environments. It also has an eight-channel memory bus with 204.8 GB/s bandwidth, double that of the AMD part. For workloads that are memory-bandwidth bound, such as large-scale database operations or high-performance computing workloads that stream data, the Intel part may hold an edge despite its lower compute scores. Additionally, with 28 cores and 56 threads, it provides more parallel threads for highly scalable workloads, even though the per-thread performance is lower.

The AMD part's unlocked multiplier means it can be overclocked, potentially extending its lead in compute-heavy tasks. The Intel part's locked multiplier limits such tuning. For users prioritizing raw Cinebench performance, the AMD Ryzen Threadripper 3960X is the clear choice. For users requiring ECC memory, higher memory bandwidth, or a server-class platform with more threads, the Intel Xeon Gold 6330 offers those specific features, even though its benchmark scores are lower.
