AMD EPYC 9734 vs Intel Xeon 696X Comparison

The AMD EPYC 9734 and Intel Xeon 696X are both 99th-percentile server processors, yet they achieve that status through radically different designs. Benchmark data shows a near-perfect split of 7 wins each across 14 head-to-head tests, but the nature of those wins tells a clear story: the Intel Xeon 696X dominates single-threaded and Cinebench multi-core workloads, while the AMD EPYC 9734 crushes data-processing, encryption, and physics tasks by margins exceeding 59% in some cases. The average benchmark scores reflect this divergence—the AMD EPYC 9734 posts an average of 310,619 against the Intel’s 286,102—but the per-test deltas reveal that raw core count alone does not decide these matchups.

Architecture Differences

The AMD EPYC 9734 is built on the Zen 4c architecture, codenamed Bergamo, using a 5 nm process at TSMC with 71,000 million transistors spread across 8x 73 mm² dies. The Intel Xeon 696X uses Granite Rapids architecture on a 5 nm process at Intel with 2x 598 mm² dies. The core designs diverge sharply: AMD allocates 64 KB L1 and 1 MB L2 per core, while Intel provides 112 KB L1 and 2 MB L2 per core. For shared L3 cache, AMD offers 256 MB, but Intel counters with 336 MB.

Clock speeds tell a complementary story. The AMD EPYC 9734 runs a 2.20 GHz base clock and 3.00 GHz boost clock, while the Intel Xeon 696X runs 2.40 GHz base and 4.80 GHz boost. This 1.80 GHz boost advantage explains Intel’s single-thread dominance. The thermal design points are close—340 W for AMD versus 350 W for Intel—but the socket ecosystems differ entirely: AMD uses Socket SP5, Intel uses Socket 4710.

Memory architecture also differs. The AMD part supports twelve-channel DDR5 with 460.8 GB/s bandwidth, while Intel uses eight-channel DDR5 at 409.6 GB/s. Both support ECC memory. AMD does not list integrated graphics, while Intel specifies N/A for integrated graphics. The AMD EPYC 9734 has a locked multiplier, whereas the Intel Xeon 696X has an unlocked multiplier, which is notable for a server part. Finally, the AMD chip belongs to the EPYC 9004 series, while the Intel chip is in the Xeon 600 (Granite Rapids-WS) generation.

Head-to-Head Benchmarks

The Cinebench suite is a clean sweep for the Intel Xeon 696X, but the margins are narrow. In Cinebench R15 multi-core, Intel scores 8,994 versus AMD’s 8,763, a 2.6% edge. The same 2.6% delta appears in R20 (37,475 vs 36,516) and R23 (89,227 vs 86,943). These consistent single-digit margins suggest the Intel part’s higher clock speeds compensate for its 48-core deficit in heavily threaded render workloads.

PassMark multi-thread tells a similar story at 2.6% for Intel (104,974 vs 102,286), and find prime numbers also favors Intel by 2.8% (853 vs 829). These are the only tests where Intel wins outside of single-thread. The single-thread gap is the largest Intel advantage: 3,742 vs 2,310, a 38.3% margin that appears in both the passmark_single_thread and passmark_singlethread tests.

The AMD EPYC 9734’s wins are not just more numerous in volume but vastly larger in magnitude. The biggest margin is in PassMark physics, where AMD scores 6,747 versus Intel’s 3,382—a 99.5% advantage, effectively double the performance. Random string sorting follows with 357,638 versus 180,392, a 98.3% delta. Data encryption shows AMD ahead by 59.4% (179,390 vs 112,529). Integer math favors AMD by 43.9% (823,150 vs 572,072). Floating-point math gives AMD a 22% edge (549,045 vs 450,164). Extended instructions show AMD ahead by 19% (205,925 vs 172,975), and data compression yields a 28% lead (2,900,008 vs 2,264,907).

The pattern is unmistakable: Intel wins where clock speed and per-core efficiency matter, while AMD wins overwhelmingly in throughput-heavy, parallel data operations. The 112-core AMD part excels at physics simulations and encryption because these workloads scale with core count and memory bandwidth. The Intel part’s single-thread lead does not translate into broad multi-thread dominance, as evidenced by the mere 2.6% Cinebench margins despite a 38.3% single-thread advantage.

Specification Differences

The two processors differ in nearly every core specification. The AMD EPYC 9734 has 112 cores and 224 threads versus 64 cores and 128 threads for the Intel Xeon 696X. Base clocks are 2.20 GHz for AMD and 2.40 GHz for Intel, while boost clocks are 3.00 GHz and 4.80 GHz respectively. TDP is 340 W for AMD and 350 W for Intel.

Cache hierarchies differ per core: AMD provides 64 KB L1 and 1 MB L2 per core, while Intel provides 112 KB L1 and 2 MB L2. Shared L3 is 256 MB on AMD and 336 MB on Intel. Memory bus width differs: twelve-channel for AMD versus eight-channel for Intel, yielding 460.8 GB/s versus 409.6 GB/s bandwidth.

Socket types are incompatible: AMD Socket SP5 versus Intel Socket 4710. The foundry differs (TSMC for AMD, Intel for Intel), and transistor counts are only listed for AMD at 71,000 million. Die size is 8x 73 mm² for AMD versus 2x 598 mm² for Intel. The Intel part has an unlocked multiplier; AMD’s is locked. Release dates differ by over two years: 2023-06-12 for AMD versus 2026-02-01 for Intel. The launch MSRP for AMD is $9600, while Intel’s is $5599.

Where Each One Wins

The AMD EPYC 9734 wins in workloads that exploit massive parallelism and memory bandwidth. Data encryption (59.4% lead), integer math (43.9%), and floating-point math (22%) all favor AMD. The physics test is the standout: AMD scores nearly double Intel’s result (99.5% delta). Random string sorting (98.3%) and data compression (28%) further cement AMD’s position for database and scientific computing tasks. The twelve-channel memory bus likely contributes to these wins, as does the 112-core count. For any workload involving encryption, compression, or physical simulation, the AMD part is the clear choice.

The Intel Xeon 696X wins in single-threaded and lightly threaded scenarios. Its 38.3% single-thread lead is the largest of any test, driven by the 4.80 GHz boost clock. Cinebench multi-core results (2.6% across R15, R20, R23) show Intel’s advantage persists even in heavily threaded render workloads, thanks to per-core efficiency. Find prime numbers (2.8% lead) and PassMark multi-thread (2.6% lead) round out Intel’s wins. For applications that are latency-sensitive, rely on single-thread performance, or use rendering engines that benefit from higher clocks, the Intel part delivers.

The average benchmark scores reinforce this split: AMD’s average of 310,619 sits 8.6% above Intel’s 286,102, but AMD’s nearest rivals include the AMD EPYC 9575F (deltaPct -0.4) and Intel Xeon 6781P (deltaPct -1.6), while Intel’s rivals include the AMD EPYC 9565 (deltaPct 0.2) and AMD EPYC 9555P (deltaPct -0.3). Both processors sit at the 99th percentile, but they serve different performance profiles.

The Verdict

The data presents two distinct value propositions. The AMD EPYC 9734 is the throughput king: it wins 7 tests, but those wins include the largest margins in the entire comparison—99.5% in physics, 98.3% in random string sorting, and 59.4% in encryption. Its 112 cores and 224 threads provide 460.8 GB/s of memory bandwidth, which translates into dominance for data-heavy server workloads. The 28% compression lead and 43.9% integer math lead make it the obvious choice for database servers, scientific computing, and any environment where parallel data processing is the bottleneck.

The Intel Xeon 696X is the clock-speed specialist: its 4.80 GHz boost clock delivers a 38.3% single-thread advantage and consistent 2.6% wins across all Cinebench versions. For users running legacy software that cannot scale beyond a few threads, or rendering workloads that respond to higher clocks rather than raw core counts, the Intel part is technically superior. Its 336 MB L3 cache and 2 MB L2 per core also provide a larger cache footprint.

Choose the AMD EPYC 9734 if your workloads involve encryption, compression, physics simulation, or massive integer/floating-point math. Choose the Intel Xeon 696X if single-thread responsiveness, Cinebench-style rendering, or clock-sensitive applications are your priority. The 7-7 win split masks the reality that AMD’s wins are decisive while Intel’s are narrow—except for single-thread, where Intel’s margin is overwhelming. The AMD part costs more at launch MSRP ($9600 vs $5599), but the benchmark data shows it delivers substantially higher throughput in the workloads where it leads.
