AMD EPYC 7313P vs Intel Core Ultra 5 235HX Comparison

The Intel Core Ultra 5 235HX and AMD EPYC 7313P represent two fundamentally different computing philosophies: a mobile-first, high-frequency design versus a server-oriented, high-core-count workhorse. The benchmark data shows a clear split, with the EPYC 7313P winning 12 of 17 head-to-head tests, while the Core Ultra 5 235HX dominates in specific single-thread and math-heavy workloads. The EPYC’s overall average benchmark score of 53,206 edges out the Core Ultra’s 52,073, a difference of roughly 2.2%, placing both at the 91st percentile among all CPUs. This is a contest between raw throughput and specialized processing power, and the right choice depends entirely on the workload.

The Verdict

The AMD EPYC 7313P is the default pick for multi-threaded, server-centric workloads. It wins every Cinebench test, from R15 multicore (3,522 vs 3,500) through R23 multicore (34,952 vs 34,731), though the margins are slim, hovering around 0.6%. Its advantages are far more pronounced in PassMark integer math, where it scores 145,558 against 97,177 — a 33.2% lead — and in data compression, where it posts 528,167 versus 426,417, a 19.3% gap. The EPYC also crushes the field in physics simulation, scoring 4,229 versus 2,550, a 39.7% advantage. If your work involves databases, virtualization, or heavy integer math, the EPYC 7313P is the clear winner.

The Intel Core Ultra 5 235HX is the specialist’s tool. It wins PassMark single-thread by a massive 77.8% (4,683 vs 2,634), and it leads floating-point math by 57.8% (129,819 vs 82,260). It also wins extended instructions (34,808 vs 32,784, a 6.2% edge) and prime number finding (361 vs 346, a 4.3% lead). For scientific computing, financial modeling, or any workload that leans on floating-point operations, the Core Ultra 5 235HX is the superior choice. It achieves this despite having fewer cores (14 vs 16) and threads (14 vs 32), highlighting its architectural efficiency.

Architecture Differences

The two CPUs come from different eras and design goals. The Intel Core Ultra 5 235HX is built on Arrow Lake-HX, a 3nm TSMC process, packing 17,800 million transistors into a 243 mm² die. It features 14 cores and 14 threads, with a base clock of 2.90 GHz and a boost of 5.10 GHz. Its cache layout includes 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3. It supports DDR5 memory via a dual-channel bus, delivering 102.4 GB/s of bandwidth. The chip includes integrated Arc Xe-LPG Graphics with 48 execution units, making it a self-contained mobile solution. It uses the Intel BGA 2114 socket and has an unlocked multiplier.

The AMD EPYC 7313P is a Zen 3 Milan server chip, fabricated on a 7nm TSMC process. It uses 16,600 million transistors across four 81 mm² chiplets, totaling a 4x 81 mm² die size. It offers 16 cores and 32 threads, with a base clock of 3.00 GHz and a boost of 3.70 GHz. Its cache hierarchy is notably different: 64 KB of L1 per core, 512 KB of L2 per core, and a massive 128 MB of shared L3 — over five times the Intel’s L3. It supports DDR4 memory across an eight-channel bus, achieving 204.8 GB/s of bandwidth, double the Intel’s throughput. It also supports ECC memory, a critical feature for server reliability. The EPYC uses the AMD Socket SP3 and its multiplier is locked.

The process node difference is stark: 3nm versus 7nm, giving Intel a density and power efficiency advantage. However, the EPYC compensates with more cores, threads, and cache, plus a wider memory bus. The Intel chip’s 55W TDP is dramatically lower than the EPYC’s 155W, reflecting their different market segments — mobile versus server/workstation. The EPYC also offers 128 PCIe Gen 4 lanes, while the Intel provides 20 PCIe Gen 5 lanes, underscoring the server chip’s expandability focus.

Head-to-Head Benchmarks

The EPYC 7313P sweeps the Cinebench suite, but the margins are consistent and narrow. It wins R15 multicore by 0.6% (3,522 vs 3,500), R20 multicore by 0.6% (14,679 vs 14,587), and R23 multicore by 0.6% (34,952 vs 34,731). The same pattern holds for single-core tests: R15 single (497 vs 494), R20 single (2,072 vs 2,059), and R23 single (4,934 vs 4,903), all with a 0.6% delta. This suggests the EPYC’s higher base clock (3.00 GHz vs 2.90 GHz) gives it a slight edge in these lightly-threaded tests, despite the Intel’s higher boost clock.

The PassMark suite reveals the true character of each chip. The EPYC dominates integer math with a 33.2% lead (145,558 vs 97,177), a result that aligns with its higher thread count and larger L3 cache. It also wins data compression by 19.3% (528,167 vs 426,417), data encryption by 8.5% (35,727 vs 32,697), random string sorting by 18.6% (62,596 vs 50,929), and physics by 39.7% (4,229 vs 2,550). The multithread score shows a slim 0.7% EPYC advantage (41,121 vs 40,849), indicating that the Intel chip’s 14 threads are remarkably competitive against the EPYC’s 32 threads in general parallel workloads.

The Intel Core Ultra 5 235HX wins the most decisive battles. Its single-thread score of 4,683 versus 2,634 is a 77.8% blowout, reflecting its 5.10 GHz boost clock against the EPYC’s 3.70 GHz. Floating-point math goes to Intel by 57.8% (129,819 vs 82,260), a massive edge that likely stems from its newer architecture and higher clock speeds. Intel also wins extended instructions by 6.2% (34,808 vs 32,784) and prime number finding by 4.3% (361 vs 346). These wins are concentrated in areas where per-core performance and SIMD efficiency matter more than raw core counts.
