AMD Ryzen Threadripper PRO 5945WX vs Intel Xeon Gold 6330 Comparison

The Verdict

The benchmark data presents a clear and consistent picture: the AMD Ryzen Threadripper PRO 5945WX wins every single head-to-head test against the Intel Xeon Gold 6330, with a 6 to 0 win count in the recorded benchmarks. The AMD part leads in both single-core and multi-core Cinebench workloads, with every delta resting between 10.6% and 10.7% in its favor. The Intel Xeon Gold 6330 does not win a single recorded benchmark in this comparison.

For users prioritizing raw per-thread performance, particularly for lightly threaded workloads or applications that depend on high clock speeds, the AMD Ryzen Threadripper PRO 5945WX is the clear selection. Its single-core scores are consistently higher across all Cinebench versions. For those who need many threads, the Intel Xeon Gold 6330 offers 28 cores and 56 threads, which is more than double the core count of the AMD part, but the benchmark data shows that the AMD chip still produces higher multicore scores despite having fewer physical cores.

The data suggests that the AMD processor provides a superior performance profile in every measured scenario. The average benchmark score for the AMD part is 9348, while the Intel part averages 8939. Both processors sit in the same percentile versus all CPUs, at 65, but the AMD part holds a lead in the average score. The verdict is straightforward: based on the recorded measurements, the AMD Ryzen Threadripper PRO 5945WX outperforms the Intel Xeon Gold 6330 in every tested application, but the Intel part has its own distinct role based on its core count, which is discussed in the next section.

Where Each One Wins

The AMD Ryzen Threadripper PRO 5945WX wins in every benchmark category recorded in the database. The most substantial wins are in the multicore tests, where the AMD part achieves a Cinebench R23 multicore score of 34204, compared to 30906 for the Intel. This is a 10.7% difference. The same pattern holds for the R20 multicore score: 14365 for the AMD versus 12980 for the Intel. Even in the older R15 multicore test, the AMD scores 3447 versus 3115, again a 10.7% lead.

The single-core measurements also favor the AMD. In Cinebench R23 single-core, the AMD scores 4828 versus 4363 for the Intel, a 10.7% delta. The R20 single-core test shows 2027 versus 1832, a 10.6% difference, and the R15 single-core test shows 486 versus 439, a 10.7% delta. The Geekbench results mirror this pattern: the AMD scores 13371 in multicore and 2059 in single-core, while the Intel does not have a recorded Geekbench score in the database.

The Intel Xeon Gold 6330, therefore, does not win any benchmark. Its role would be for workloads that require a larger number of physical cores, as it offers 28 cores and 56 threads versus the AMD's 12 cores and 24 threads. The database does not provide a benchmark that specifically isolates core-count scaling, so this advantage is not measured. The AMD, however, achieves its winning multicore scores with fewer cores, meaning its per-core efficiency and higher clock speeds are the deciding factors in the recorded tests.

Architecture Differences

The two processors come from fundamentally different architectures. The AMD Ryzen Threadripper PRO 5945WX is built on the Zen 3 architecture, codenamed Chagall PRO, and belongs to the 5000 series. It is manufactured on a 7 nm process at TSMC, with 16,600 million transistors and a die size of 4x 81 mm². The Intel Xeon Gold 6330 uses the Ice Lake architecture, specifically Ice Lake-SP, and is manufactured on a 10nm process at Intel. The Intel chip has no recorded transistor or die size data.

The core configurations differ significantly. The AMD has 12 cores and 24 threads. The Intel has 28 cores and 56 threads. Both have a 64 KB L1 cache per core. However, the L2 cache differs: the AMD has 512 KB per core, while the Intel has 1 MB per core. The L3 cache is also different: the AMD has 64 MB, while the Intel has 42 MB shared.

Clock speeds are a major differentiator. The AMD has a base clock of 4.10 GHz and a boost clock of 4.50 GHz. The Intel has a base clock of 2000.00 MHz (which is 2.00 GHz) and a boost clock of 3.10 GHz. This explains the single-core advantage of the AMD, as it runs at much higher frequencies.

Memory support is similar in many respects. Both support DDR4 memory, have an eight-channel memory bus, and feature 204.8 GB/s memory bandwidth. Both also support ECC memory. The PCIe configuration is where they differ: the AMD has Gen 4 with 128 lanes (CPU only), while the Intel has Gen 4 with 64 lanes (CPU only).

The sockets are incompatible: The AMD uses Socket WRX8, while the Intel uses Socket 4189. Both are for the server/workstation market segment and are in active production. The AMD was released on 2022-03-07, while the Intel was released on 2021-04-05. The AMD has a total of 16,600 million transistors, but the Intel's count is not recorded.

Head-to-Head Benchmarks

The head-to-head data is remarkably consistent. In the Cinebench R15 multicore test, the AMD Ryzen Threadripper PRO 5945WX scores 3447 versus 3115 for the Intel Xeon Gold 6330, a 10.7% delta. The single-core R15 test shows a 10.7% delta as well, with scores of 486 and 439.

Moving to Cinebench R20, the AMD wins multicore with 14365 against 12980, a 10.7% difference, and single-core with 2027 against 1832, a 10.6% difference. In the R23 benchmark, the AMD scores 34204 in multicore against 30906, a 10.7% lead, and 4828 in single-core against 4363, also a 10.7% lead.

The most significant wins come in the multicore tests, but the single-core wins are notable because the Intel has more than double the cores. The AMD manages to win the multicore tests with a 12-core chip, which speaks to its clock speed advantage (4.50 GHz boost versus 3.10 GHz boost) and architecture efficiency.

The largest margins are all in the range of 10.6% to 10.7%, meaning the performance gap is nearly identical across every generation of Cinebench. The Geekbench multi/single scores are also listed, but the Intel does not have a recorded Geekbench score, so no delta exists. The Intel's average benchmark score is 8939, while the AMD's is 9348, a difference of about 4.4% in favor of the AMD. The nearest rival to the AMD is the Intel Xeon Platinum 8180, which is 0.6% behind, while the Intel's nearest rival is the Intel Core i7-8650U, which is 0.1% ahead.

The L1 cache is identical (64 KB per core), as is memory support (DDR4, eight-channel, 204.8 GB/s bandwidth, ECC true). Both are in the server/workstation segment and are active. The AMD has a higher TDP despite having fewer cores, likely due to its higher clock speeds. The AMD also has a smaller process node (7nm vs 10nm) and a larger L3 cache. The Intel has a larger L2 cache per core.
