AMD EPYC 9224 vs Intel Xeon Gold 6342 Comparison

The Verdict

The recorded data paints a clear picture: the Intel Xeon Gold 6342 wins all six head-to-head Cinebench tests against the AMD EPYC 9224. The margins are narrow but consistent, ranging from 4.1% to 4.2% in favor of Intel across single-core and multi-core workloads. The Intel processor posts an average benchmark score of 11574, placing it in the 67th percentile of all CPUs, while the AMD EPYC 9224 averages 11118, sitting in the 66th percentile. For users prioritizing raw Cinebench rendering performance, the Intel Xeon Gold 6342 is the statistically stronger choice, despite being an older design.

The AMD EPYC 9224, however, is not without its merits. It carries a launch MSRP of $1825, while the Intel part has no recorded launch price in the database. The AMD chip draws 200W compared to Intel's 230W, and it offers a faster boost clock of 3.70 GHz versus 3.50 GHz. The EPYC also brings modern platform features: DDR5 memory, a twelve-channel memory bus, and PCIe Gen 5 with 128 lanes. These are significant architectural advantages that the benchmarks alone do not capture. The verdict depends on workload: if Cinebench scores are the priority, choose Intel; if platform features, memory bandwidth, and connectivity matter more, AMD is the better fit.

Architecture Differences

The Intel Xeon Gold 6342 is built on Ice Lake-SP architecture, manufactured on Intel's 10 nm process. It uses the Intel Socket 4189 and belongs to the Xeon Gold generation. The AMD EPYC 9224 is based on Zen 4 architecture, codenamed Genoa, manufactured on TSMC's 5 nm node. It uses the AMD Socket SP5 and belongs to the EPYC 9004 series. The process node difference is stark: 10 nm versus 5 nm, with the EPYC built by TSMC while Intel uses its own foundry.

Core and thread counts are identical: both have 24 cores and 48 threads. Cache configurations differ notably. Both have 64 KB of L1 per core and 1 MB of L2 per core. The L3 cache, however, is 36 MB shared on the Intel part versus 64 MB shared on the AMD part. The EPYC also has a much larger transistor count at 26,280 million, with a die size of 4x 72 mm², while the Intel part has no recorded transistor or die size data.

Memory architecture is a major differentiator. The Intel Xeon Gold 6342 supports DDR4 with an eight-channel memory bus and a bandwidth of 204.8 GB/s. The AMD EPYC 9224 supports DDR5 with a twelve-channel memory bus and a bandwidth of 460.8 GB/s. That is more than double the memory bandwidth on the AMD side. PCIe capabilities also favor AMD: the EPYC provides Gen 5 with 128 lanes (CPU only), while Intel provides Gen 4 with 64 lanes (CPU only). Both support ECC memory, and neither has integrated graphics.

Head-to-Head Benchmarks

The head-to-head data shows a sweep for Intel, but the margins are tight. In Cinebench R15 multicore, the Intel Xeon Gold 6342 scores 4033 against the EPYC's 3874, a 4.1% advantage. In R15 single-core, Intel scores 569 versus 546, a 4.2% edge. The pattern holds in R20: multicore is 16805 for Intel versus 16144 for AMD, a 4.1% delta; single-core is 2372 versus 2278, again 4.1%. R23 multicore shows 40014 for Intel versus 38439 for AMD, a 4.1% gap; single-core is 5649 versus 5426, also 4.1%.

These are consistent results, not outliers. Intel wins all six tests, but the largest margin is just 4.2%. The AMD EPYC 9224's higher boost clock of 3.70 GHz does not translate into a single-core win, likely because the Intel part's base clock is higher at 2.80 GHz versus 2.50 GHz, and the architectures differ in IPC efficiency. The data indicates that in this specific benchmark suite, the Intel design holds a small but reliable performance lead across both threaded and unthreaded workloads.

The average benchmark scores corroborate the head-to-head results. The Intel Xeon Gold 6342 averages 11574, while the AMD EPYC 9224 averages 11118. The Intel part's nearest rivals include the AMD Ryzen 9 PRO 7945 (average 11469, delta 0.9%), the Intel Core i7-1185G7 (average 11697, delta -1.1%), and the Intel Core i7-4790K (average 11745, delta -1.5%). The AMD EPYC 9224's nearest rivals include the AMD EPYC 7542 (average 11152, delta -0.3%), the Intel Core i7-6700 (average 11074, delta 0.4%), and the Intel Xeon Gold 6336Y (average 11191, delta -0.6%). These figures show both processors sit in a similar performance tier, with the Intel part edging ahead by roughly 4% in the direct comparison.

Where Each One Wins

The Intel Xeon Gold 6342 wins on every recorded benchmark. In Cinebench R15 multicore, it leads by 4.1% (4033 versus 3874). In R15 single-core, it leads by 4.2% (569 versus 546). R20 multicore shows a 4.1% lead (16805 versus 16144), and R20 single-core shows a 4.1% lead (2372 versus 2278). R23 multicore is 4.1% ahead (40014 versus 38439), and R23 single-core is 4.1% ahead (5649 versus 5426). The Intel part also has a higher average benchmark score (11574 versus 11118) and a higher percentile ranking (67th versus 66th). It has a higher base clock and a lower TDP-to-performance ratio is not directly measurable, but the TDP is higher at 230W versus 200W.

The AMD EPYC 9224 wins on platform-level features that are not reflected in Cinebench scores. It offers more than double the memory bandwidth (460.8 GB/s versus 204.8 GB/s) and supports DDR5 instead of DDR4. It has a twelve-channel memory bus versus eight-channel. It provides PCIe Gen 5 with 128 lanes versus PCIe Gen 4 with 64 lanes, which is a decisive advantage for high-throughput storage and networking. It has a larger L3 cache (64 MB versus 36 MB), a more modern 5 nm process, and a lower TDP (200W versus 230W). It also has a higher boost clock (3.70 GHz versus 3.50 GHz) and a recorded launch MSRP of $1825, while the Intel part has no recorded launch price.

For workloads that are heavily dependent on memory bandwidth, such as large-scale database operations, in-memory analytics, or high-performance computing with massive data sets, the AMD EPYC 9224 is likely the stronger choice despite losing the Cinebench tests. For workloads that are purely compute-bound and measured by Cinebench-style rendering, the Intel Xeon Gold 6342 holds the edge. The data shows a trade-off: Intel wins the benchmark suite, AMD wins the platform specification battle.
