AMD EPYC 4464P vs Intel Core Ultra 7 265 Comparison

The AMD EPYC 4464P and Intel Core Ultra 7 265 are both 65W processors, but they target different ecosystems and workloads. The data shows a clear split: Intel wins 14 of 17 head-to-head benchmarks, yet AMD takes decisive victories in specific data-centric tasks. The EPYC 4464P, a 12-core/24-thread Zen 4 part on AM5, averages a 64756 benchmark score, placing it 1% ahead of the Core Ultra 7 265’s 64112 average. Both sit at the 95th percentile of all CPUs. The Core Ultra 7 265, with 20 cores and 20 threads on Arrow Lake, counters with superior single-thread and floating-point performance. The choice hinges on workload: the EPYC’s 64 MB of L3 cache and ECC support make it a server/workstation part, while the Core Ultra 7’s 30 MB L3 and desktop socket point to mainstream use. The following sections dissect the architectural and benchmark data to clarify which processor fits which role.

The Verdict — who should pick which, strictly from the data

For users prioritizing raw multi-threaded throughput in rendering and compression, the Intel Core Ultra 7 265 is the stronger pick. It leads in all three Cinebench multicore tests (R15, R20, R23) by a consistent 3.4% margin, and its PassMark multithread score of 48915 beats the EPYC’s 47312 by 3.3%. The data also shows Intel dominating floating-point math by a massive 46.9% (172546 vs 91668), which suggests a decisive advantage for scientific or financial workloads that rely on FPU throughput. The Core Ultra 7 265 also wins single-thread tests by 10.8% (4632 vs 4130), making it the better choice for lightly-threaded applications and responsive desktop use.

Conversely, the AMD EPYC 4464P is the pick for data-heavy server workloads. It wins PassMark data compression by 13.7% (575076 vs 505578), integer math by 17.1% (160011 vs 136683), and random string sorting by 13.5% (70443 vs 62044). These three wins, combined with ECC memory support and 28 PCIe Gen 5 lanes (vs Intel’s 20), position it for database, encryption, and file-server duties where data integrity and I/O bandwidth matter more than raw FPU speed. The EPYC also has a 13,140 million transistor count on a 5nm node, whereas Intel uses 17,800 million transistors on a 3nm node — but the EPYC’s larger 64 MB L3 cache likely contributes to its data-crunching wins.

The verdict from the data is straightforward: choose the Intel Core Ultra 7 265 for general desktop performance, floating-point math, and single-thread responsiveness. Choose the AMD EPYC 4464P for server-class tasks involving compression, integer math, and sorting, where its wins are substantial and its ECC support is a non-negotiable feature. The EPYC’s launch MSRP is $429, while the Core Ultra 7 265’s is $394, but price should not be the deciding factor given the divergent feature sets.

Architecture Differences — node, cores, cache, features that differ

The two CPUs represent fundamentally different design philosophies. The AMD EPYC 4464P uses the Zen 4 architecture on a 5nm TSMC process, with a codename of Raphael and a generation label of "EPYC (Zen 4 (Raphael))". It packs 12 cores and 24 threads, leveraging simultaneous multithreading (SMT) to double thread count. Its die size is listed as 2x 71 mm², totaling 13,140 million transistors. The Intel Core Ultra 7 265, by contrast, uses the Arrow Lake architecture on a 3nm TSMC process, with a codename of Arrow Lake-S. It has 20 cores and 20 threads — no SMT — with a single 243 mm² die containing 17,800 million transistors.

Cache hierarchies diverge sharply. The EPYC allocates 64 KB L1 and 1 MB L2 per core, with a shared 64 MB L3 cache. The Core Ultra 7 265 provides 192 KB L1 and 3 MB L2 per core, but only 30 MB shared L3. This 2.13x difference in L3 capacity (64 MB vs 30 MB) likely explains the EPYC’s wins in data compression and sorting, where larger working sets fit in cache. Intel’s per-core L2 is 3x larger (3 MB vs 1 MB), which may benefit certain single-thread workloads, but the shared pool is smaller.

Memory and I/O also differ. Both support DDR5 dual-channel memory, but Intel’s memory bandwidth is listed at 102.4 GB/s versus AMD’s 83.2 GB/s — a 23% advantage for Intel. ECC memory is supported on the EPYC but not on the Core Ultra 7. PCIe lanes favor AMD: 28 Gen 5 lanes (CPU only) versus Intel’s 20 Gen 5 lanes. Integrated graphics differ as well: the EPYC has Radeon Graphics, while the Core Ultra 7 has Arc Xe-LPG Graphics 32EU. The EPYC is a server/workstation segment part on AMD Socket AM5, while the Core Ultra 7 is a desktop part on Intel Socket 1851. Both have locked multipliers and are currently active in production.

Where Each One Wins — use-case split based on benchmark wins

The benchmark data reveals a clear division of labor. The Intel Core Ultra 7 265 wins all six Cinebench tests (R15, R20, R23, both single and multicore) by 3.4% each time. It also wins PassMark data encryption by 8.1% (39431 vs 36227), extended instructions by 2.3% (39768 vs 38866), find prime numbers by 20.6% (412 vs 327), floating-point math by 46.9% (172546 vs 91668), multithread by 3.3% (48915 vs 47312), physics by 4.6% (3019 vs 2879), and single-thread by 10.8% (4632 vs 4130). These wins span rendering, encryption, prime-number calculation, FPU-heavy math, and overall multithreaded performance.

The AMD EPYC 4464P wins only three benchmarks, but they are decisive in their domains. Data compression shows a 13.7% lead (575076 vs 505578), integer math leads by 17.1% (160011 vs 136683), and random string sorting leads by 13.5% (70443 vs 62044). These are all memory-latency-sensitive and cache-capacity-dependent workloads. The EPYC’s 64 MB L3 cache and 24 threads (vs Intel’s 20) appear to give it an edge in handling large data sets that require frequent random access. The wins are not marginal — they are double-digit percentage gaps that would be noticeable in database indexing, log processing, or compression workloads.

For mixed workloads, the data suggests Intel wins more often but AMD wins bigger where it wins. Intel’s 14 wins are mostly in the 2-8% range, while AMD’s 3 wins are all above 13%. This implies that the EPYC is specialized for data-dense tasks, while the Core Ultra 7 is a more general-purpose performer. The single-thread gap of 10.8% in Intel’s favor is significant for desktop responsiveness, but the EPYC’s integer math lead of 17.1% is crucial for database queries that rely on integer operations.

Head-to-Head Benchmarks — walk through the biggest wins each way with exact numbers

The most striking result is in PassMark floating-point math, where the Intel Core Ultra 7 265 scores 172546 against the EPYC’s 91668, a 46.9% difference. This is not a marginal gap; it indicates a fundamental architectural advantage in FPU throughput, likely stemming from the Arrow Lake design’s wider execution units or higher memory bandwidth (102.4 GB/s vs 83.2 GB/s). For any workload that relies heavily on floating-point operations — such as 3D rendering, scientific simulations, or machine learning inference — this data suggests the Core Ultra 7 is overwhelmingly faster.

The second-largest Intel win is in PassMark find prime numbers, with a score of 412 versus 327, a 20.6% lead. This benchmark is integer-heavy and often tests branch prediction and loop performance. Intel’s 20 physical cores (vs AMD’s 12) may contribute here, as prime-number finding scales well with core count. Intel also takes single-thread by 10.8% (4632 vs 4130), which is consistent across both PassMark single-thread and singlethread entries. The Cinebench results are uniform: Intel leads all six tests by exactly 3.4%, suggesting a consistent per-clock advantage across both single and multicore workloads.

For AMD, the biggest win is PassMark integer math at 160011 versus 136683, a 17.1% lead. This is notable because Intel wins find prime numbers (also integer-based) by 20.6%, but AMD wins the broader integer math test. The difference may lie in the EPYC’s 64 MB L3 cache, which can hold more integer data for repeated operations. AMD also wins data compression by 13.7% (575076 vs 505578) and random string sorting by 13.5% (70443 vs 62044). These three wins are clustered around data manipulation, reinforcing the EPYC’s server-oriented strengths. The multithread score goes to Intel by 3.3% (48915 vs 47312), but the EPYC’s 24 threads vs Intel’s 20 does not overcome Intel’s higher per-core performance in this aggregate test.
