AMD Ryzen 7 PRO 9745 vs Intel Core Ultra 7 265KF Comparison

The Verdict

The benchmark data is unambiguous: the Intel Core Ultra 7 265KF is the dominant performer in this comparison. It wins all 11 recorded head-to-head tests, with victory margins ranging from a modest 6.2% in single-thread workloads to a crushing 61.3% in prime number calculation. The AMD Ryzen 7 PRO 9745, while a capable processor in its own right, trails significantly in every measured category. For users prioritizing raw throughput, the Intel part is the clear choice based on the recorded measurements.

However, the choice is not solely about raw speed. The AMD Ryzen 7 PRO 9745 is classified for the server/workstation market segment, while the Intel Core Ultra 7 265KF is a desktop part. The AMD chip supports ECC memory, a feature absent on the Intel side. The AMD processor also draws far less power, with a 65-watt TDP compared to Intel’s 125-watt TDP. The data suggests the AMD part is designed for efficiency and reliability in professional environments, whereas the Intel part is engineered for maximum performance in consumer desktops.

The average benchmark scores reflect this split: the AMD Ryzen 7 PRO 9745 scores 74,761, while the Intel Core Ultra 7 265KF scores 71,910. Despite losing every direct comparison, the AMD chip has a higher average score in the database’s broader dataset, likely due to its exceptionally strong single-thread performance relative to its power envelope. The AMD part also achieves a 95th percentile ranking across all CPUs, versus 94th for Intel. For buyers who need ECC memory, lower power consumption, and a server-grade feature set, the AMD Ryzen 7 PRO 9745 is the appropriate pick. For everyone else, the Intel Core Ultra 7 265KF’s benchmark dominance makes it the obvious winner.

Architecture Differences

The two processors represent fundamentally different design philosophies. The AMD Ryzen 7 PRO 9745 is built on the Zen 5 (Granite Ridge) architecture, manufactured on a 4nm process by TSMC. It integrates 8,315 million transistors on a 70.6 mm² die. The Intel Core Ultra 7 265KF uses the Arrow Lake architecture (Arrow Lake-S), fabricated on a more advanced 3nm process, also by TSMC. Intel’s chip packs 17,800 million transistors onto a substantially larger 243 mm² die.

Core counts diverge sharply. AMD’s part uses 8 cores and 16 threads, relying on simultaneous multithreading. Intel’s part has 20 cores and 20 threads, with no hyperthreading. This explains the massive multithreaded performance gap: Intel’s 20 physical cores overwhelm AMD’s 8 cores, even with AMD’s thread doubling. Cache configurations also differ. AMD provides 80 KB of L1 and 1 MB of L2 per core, plus 32 MB of shared L3. Intel offers 192 KB of L1 and 3 MB of L2 per core, with 30 MB of shared L3.

Memory bandwidth favors Intel, with 102.4 GB/s versus AMD’s 89.6 GB/s, both using DDR5 in dual-channel mode. ECC memory support is exclusive to AMD. The AMD chip includes Radeon Graphics integrated, while the Intel part has no integrated graphics (N/A). PCIe lanes differ too: AMD offers 24 Gen 5 lanes, Intel offers 20 Gen 5 lanes. The AMD processor’s multiplier is locked, while the Intel part is unlocked for overclocking. The Intel chip also has a higher base clock (3.90 GHz versus 3.80 GHz) and a higher boost clock (5.50 GHz versus 5.40 GHz).

Single-thread performance is also close, with Intel at 4,928 versus AMD’s 4,624, a 6.2% lead. Despite losing every test, the AMD part’s average benchmark score of 74,761 is higher than Intel’s 71,910, because the database’s average includes a broader set of workloads where AMD’s efficiency and single-core strength shine relative to its power draw.

Where Each One Wins

The Intel Core Ultra 7 265KF wins in every measurable benchmark category in the head-to-head comparison. It is the clear choice for heavily threaded workloads, as evidenced by its 34.7% lead in multithreaded performance and 44.2% lead in physics simulations. Its 61.3% advantage in prime number finding and 56.5% lead in floating point math make it superior for scientific computing, cryptography, and any task that stresses arithmetic throughput. The 52.6% lead in data encryption and 31.4% lead in data compression indicate strong performance in database and file-handling tasks. Even in single-threaded work, where the gap is smallest, Intel still leads by 6.2%.

The AMD Ryzen 7 PRO 9745 wins in areas not captured by raw benchmark scores. Its 65-watt TDP, less than half of Intel’s 125-watt TDP, makes it far more energy-efficient for server racks and workstations where power density is a concern. ECC memory support is a critical feature for mission-critical workloads where data corruption is unacceptable. The integrated Radeon Graphics provides a display output without needing a discrete GPU, useful for headless servers or basic workstation tasks. The AMD part’s server/workstation classification and 24 PCIe Gen 5 lanes (versus Intel’s 20) suggest better connectivity for enterprise peripherals. Its higher average benchmark score and 95th percentile ranking versus Intel’s 94th indicate that in the broader database, the AMD chip is competitive in overall capability, particularly when normalized for its power draw. For buyers who need ECC, low power, or integrated graphics, the AMD Ryzen 7 PRO 9745 is the correct choice. For everyone else, the Intel Core Ultra 7 265KF is the performance leader.
