AMD EPYC 4465P vs Intel Core Ultra 7 265F Comparison

The AMD EPYC 4465P and Intel Core Ultra 7 265F are both 65-watt processors aimed at very different system types, yet their benchmark results are remarkably close. The EPYC 4465P wins 12 of the 17 recorded head-to-head tests, while the Core Ultra 7 265F takes 5. The decisive factor is not raw compute volume but workload character: the AMD part dominates integer math, compression, and physics simulation, while the Intel part leads in floating-point, encryption, and single-threaded PassMark scores. The EPYC 4465P posts a 2.2% lead in every Cinebench test, a consistent margin that reflects its architecture's efficiency. The Core Ultra 7 265F counters with a 39.1% win in floating-point math, a massive swing that defines its identity. The database places both at the 93rd percentile among all CPUs, and their average benchmark scores (66925 for AMD, 64438 for Intel) differ by only 3.9%. The AMD EPYC 4465P is the choice for server and workstation workloads, especially those involving integer-heavy processing, while the Intel Core Ultra 7 265F suits desktop tasks that leverage floating-point throughput and faster single-thread PassMark results.

The Verdict

The AMD EPYC 4465P is the stronger overall processor in the recorded benchmark suite. It wins 12 of 17 head-to-head tests, including all six Cinebench runs by a uniform 2.2% to 2.3% margin. The Intel Core Ultra 7 265F wins only 5 tests, but those wins are decisive in specific domains: floating-point math (39.1% ahead), data encryption (18.5% ahead), prime number finding (18.7% ahead), and PassMark single-thread (3.7% ahead). For users prioritizing Cinebench render workloads, integer math, compression, extended instructions, or physics simulation, the EPYC 4465P is the clear pick. For users running encryption-heavy tasks, floating-point calculations, or workloads that favor PassMark's single-thread metric, the Core Ultra 7 265F is superior. The EPYC 4465P's market segment is Server/Workstation, and its 93rd percentile ranking alongside a 0.1% delta to the Intel Core Ultra 5 250K Plus in its nearest rival list confirms it sits at the top of the mid-range compute tier. The Core Ultra 7 265F, a Desktop part, also hits the 93rd percentile but trails in average score by 3.9%. The verdict is workload-dependent, but the AMD part's broader win count and Cinebench sweep make it the default recommendation for multi-threaded productivity.

Architecture Differences

The two processors diverge fundamentally in core configuration and cache layout. The AMD EPYC 4465P has 12 cores and 24 threads, while the Intel Core Ultra 7 265F has 20 cores and 20 threads, so Intel offers 67% more physical cores but no hyperthreading, while AMD relies on simultaneous multithreading to double its thread count. The EPYC 4465P uses Zen 5 architecture on a 4 nm TSMC process, while the Core Ultra 7 265F uses Arrow Lake on a 3 nm TSMC process. The EPYC's cache hierarchy is notable: 80 KB L1 per core, 1 MB L2 per core, and 64 MB shared L3. Intel counters with 192 KB L1 per core, 3 MB L2 per core, but only 30 MB shared L3. The AMD part's 64 MB L3 is more than double Intel's 30 MB, a likely contributor to its 13.8% win in data compression and 26.4% lead in integer math. The EPYC 4465P is built on a 2x 70.6 mm² die with 16,630 million transistors, while the Core Ultra 7 265F uses a single 243 mm² die with 17,800 million transistors. Both support DDR5 dual-channel memory, but Intel's memory bandwidth is higher at 102.4 GB/s versus AMD's 89.6 GB/s. The EPYC supports ECC memory; the Core Ultra 7 does not. The AMD part includes Radeon Graphics integrated graphics, while the Intel part has no integrated graphics. The EPYC 4465P offers 24 PCIe Gen 5 lanes (CPU only), versus Intel's 20 lanes. The AMD part launches on AMD Socket AM5, while Intel uses Socket 1851. The EPYC 4465P's release date is 2025-05-12, later than the Core Ultra 7 265F's 2025-01-06. The AMD launch MSRP is $399, and the Intel launch MSRP is $379.

Head-to-Head Benchmarks

The Cinebench results show a perfect sweep for the AMD EPYC 4465P. In Cinebench R15 multi-core, AMD scores 4326 versus Intel's 4231, a 2.2% win. In R15 single-core, AMD scores 610 versus 597, again 2.2%. The R20 multi-core test shows 18025 versus 17631 (2.2%), and R20 single-core shows 2544 versus 2488 (2.3%). R23 multi-core continues the pattern: 42918 versus 41980 (2.2%), and R23 single-core is 6059 versus 5926 (2.2%). These consistent margins indicate a fundamental efficiency advantage for Zen 5 in Cinebench's rendering workloads. The PassMark suite reveals a more complex picture. AMD wins data compression by a wide margin: 577210 versus 507018, a 13.8% lead. Extended instructions favor AMD at 42867 versus 39235 (9.3%). Integer math is AMD's largest PassMark win: 174551 versus 138078, a 26.4% advantage. Physics simulation goes to AMD at 3647 versus 3172, a 15% lead. Random string sorting favors AMD at 67597 versus 62439 (8.3%). Multithread is nearly tied, with AMD at 49871 versus Intel's 49410, a slim 0.9% edge. Intel's wins are concentrated and dramatic. Floating-point math is a blowout: Intel scores 173855 versus AMD's 105833, a 39.1% advantage. Data encryption favors Intel at 39468 versus 32184, an 18.5% lead.
