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

The AMD Ryzen 7 PRO 9745 and Intel Core Ultra 7 265K represent two distinct approaches to high-end desktop computing. The AMD part is a workstation-oriented, power-efficient 8-core processor built on a dense 4 nm process, while the Intel chip is a 20-core desktop flagship built on a 3 nm node. Benchmark data from the database shows a clear split: the Intel Core Ultra 7 265K wins every single head-to-head test recorded, but the AMD Ryzen 7 PRO 9745 posts a higher average benchmark score relative to its own closest rivals. This creates an interesting dynamic where raw compute throughput favors Intel, while the AMD chip’s efficiency and platform positioning tell a different story.

Where Each One Wins

The Intel Core Ultra 7 265K is the outright performance winner in the database’s head-to-head comparisons. It takes all 11 recorded benchmarks, with victories ranging from a narrow 6.2% margin in single-threaded tests to a dominant 61.7% lead in prime number finding. The data shows a consistent pattern: the Intel part leverages its 20 cores and 20 threads to crush multi-threaded workloads, while its higher boost clock of 5.50 GHz gives it a measurable edge in single-threaded tasks. The Core Ultra 7 265K wins in integer math, floating-point math, data encryption, data compression, extended instructions, random string sorting, physics simulation, and the overall multithread score. For users running heavily parallel workloads, video encoding, or complex scientific simulations, the recorded data leaves no doubt that the Intel processor is the stronger choice.

The AMD Ryzen 7 PRO 9745, despite losing every head-to-head matchup, still holds its own in the broader database context. Its average benchmark score of 74,761 places it in the 95th percentile of all CPUs, which is one percentile point higher than the Intel part’s 94th percentile. The AMD chip also sits closer to its nearest rivals in average score, with a delta of just 0.2% compared to the AMD Ryzen 9 9950X, while the Intel part’s closest rival, the Intel Xeon 6511P, is 0.2% ahead of it. The Ryzen 7 PRO 9745’s wins are more subtle: it delivers this competitive average score with a 65 W TDP, which is dramatically lower than the Intel part’s 125 W TDP. The data suggests the AMD chip wins on efficiency and platform integration, particularly for workstation and server environments where power draw and thermal output are critical constraints.

Architecture Differences

The two processors diverge fundamentally in their core architectures. The AMD Ryzen 7 PRO 9745 uses the Granite Ridge die, based on the Zen 5 microarchitecture, and packs 8 cores with 16 threads. It is built on TSMC’s 4 nm process with 8,315 million transistors on a 70.6 mm² die. The Intel Core Ultra 7 265K, codenamed Arrow Lake-S, uses the Arrow Lake architecture with 20 cores and 20 threads, meaning it has no simultaneous multithreading. Intel’s chip is fabricated on TSMC’s 3 nm node and contains 17,800 million transistors across a 243 mm² die, making it significantly larger and more complex.

Cache hierarchies also differ substantially. The AMD part provides 80 KB of L1 cache per core, 1 MB of L2 per core, and 32 MB of shared L3. The Intel chip offers 192 KB of L1 per core, 3 MB of L2 per core, and 30 MB of shared L3. While the Intel part has more L1 and L2 per core, the AMD part has a slightly larger shared L3 pool. Both support dual-channel DDR5 memory, but the Intel chip’s memory bandwidth is rated at 102.4 GB/s, while the AMD chip’s is 89.6 GB/s. Both support ECC memory. The AMD part offers 24 PCIe Gen 5 lanes from the CPU, while the Intel chip provides 20.

Integrated graphics differ as well. The AMD Ryzen 7 PRO 9745 includes Radeon Graphics, while the Intel Core Ultra 7 265K features Arc Xe-LPG Graphics with 64 execution units. The Intel chip is socketed for LGA 1851 and has an unlocked multiplier, whereas the AMD part uses Socket AM5 and has a locked multiplier. The AMD processor targets the server and workstation segment, while the Intel part is aimed at desktop enthusiasts.

Head-to-Head Benchmarks

The head-to-head data is unambiguous: the Intel Core Ultra 7 265K wins every recorded benchmark. The largest margin comes in the prime number finding test, where Intel scores 491 versus AMD’s 188, a 61.7% advantage. Floating-point math shows a similar gap, with Intel at 189,629 versus AMD’s 82,461, a 56.5% difference. Data encryption is another blowout, with Intel scoring 48,246 against AMD’s 22,848, a 52.6% lead. These results reflect the Intel chip’s raw core count advantage in heavily parallel integer and floating-point workloads.

In more general multithreaded performance, the Intel part scores 58,594 on the PassMark multithread test, compared to AMD’s 38,201, a 34.8% advantage. The physics test shows Intel at 3,731 versus AMD’s 2,026, a 45.7% lead. Random string sorting favors Intel at 79,752 versus 49,219, a 38.3% margin. Data compression goes to Intel at 665,554 versus 457,211, a 31.3% lead, and extended instructions follow at 54,333 versus 36,800, a 32.3% advantage.

Even in the closest contests, Intel prevails. Integer math sees Intel at 143,242 versus AMD’s 124,167, a 13.3% lead. Single-threaded performance is the tightest race, with Intel at 4,928 versus AMD’s 4,624, a 6.2% margin. The data shows that while the AMD chip’s Zen 5 cores are competitive per-core, the Intel part’s higher boost clock and greater core count overwhelm the AMD processor in every measured scenario.
