AMD Ryzen 7 PRO 9745 vs Intel Core i9-14900K Comparison

The AMD Ryzen 7 PRO 9745 and Intel Core i9-14900K represent two very different approaches to high-end computing. The Intel part, a 24-core desktop flagship, wins all 11 head-to-head benchmark comparisons in the database, while the AMD, an 8-core server/workstation chip, trails in every measured test. Both processors sit at the 95th percentile of all CPUs, but the Intel's average benchmark score of 79,097 outpaces the AMD's 74,761. The data is unambiguous: for raw performance, the Intel Core i9-14900K is the superior choice. However, the AMD offers a lower 65W TDP, a smaller 70.6 mm² die, and a newer 4nm process, which may appeal to power-conscious or space-constrained deployments.

The Verdict

Based on the recorded benchmark data, the Intel Core i9-14900K is the clear winner for any workload that prioritizes speed. It wins all 11 head-to-head tests, with deltas ranging from -1.6% in single-thread to -51.2% in data encryption. The AMD Ryzen 7 PRO 9745 does not win a single comparison. For users who need maximum performance in compression, encryption, math, or multithreaded tasks, the Intel part is the only choice. The AMD, however, has a 65W TDP versus 125W, and a 70.6 mm² die versus 257 mm², making it a more efficient option for environments where power and space are limited. The AMD also offers 24 PCIe Gen 5 lanes versus 16 on the Intel, which could benefit expansion-heavy systems. But if the question is which CPU is faster, the data says Intel without exception. The Intel's average score also places it within 0.3% of the Core i9-14900KF, while the AMD's average is within 0.2% of the Ryzen 9 9950X, showing that both parts are tightly grouped with their closest rivals.

Where Each One Wins

Since the Intel Core i9-14900K wins every head-to-head benchmark, the "wins" section is a list of Intel's margins. The smallest gap is in single-thread performance, where Intel scores 4,697 against AMD's 4,624, a 1.6% advantage. This means that for lightly threaded applications, the two CPUs are nearly equivalent. The largest gap is in data encryption, where Intel scores 46,813 versus 22,848, a 51.2% lead. Floating point math shows a 46.1% gap (152,975 vs 82,461), and random string sorting is 43.4% ahead (86,971 vs 49,219). Data compression is 42.3% ahead (792,694 vs 457,211), and integer math is 41% ahead (210,622 vs 124,167). The multithread score is 58,674 for Intel versus 38,201 for AMD, a 34.9% delta, and physics is 3,140 versus 2,026, a 35.5% delta. Extended instructions and prime number finding show 18.5% and 18.6% deltas respectively. In summary, Intel dominates in every category, but the single-thread margin is small enough that the AMD's lower power draw might be a trade-off for single-threaded workloads. For any workload that scales across cores, the Intel's 24 cores and 32 threads provide a substantial advantage, as reflected in the multithread and math scores.

Architecture Differences

The two CPUs differ fundamentally in architecture. The AMD Ryzen 7 PRO 9745 is built on TSMC's 4nm process and packs 8,315 million transistors into a 70.6 mm² die. It uses the Granite Ridge codename and Zen 5 generation, with 8 cores and 16 threads. Base clock is 3.80 GHz, boost is 5.40 GHz, and TDP is 65W. It supports DDR5 memory only, with dual-channel and 89.6 GB/s bandwidth. It has 80 KB L1 per core, 1 MB L2 per core, and 32 MB shared L3. It offers 24 PCIe Gen 5 lanes and includes Radeon Graphics. It is a server/workstation part, released on 2025-09-15, and has a locked multiplier. The Intel Core i9-14900K, in contrast, uses Intel's 10nm process and a 257 mm² die. It has 24 cores and 32 threads, with a base clock of 3.20 GHz and a boost of 6.00 GHz. TDP is 125W. It supports both DDR4 and DDR5, dual-channel, and has 80 KB L1 per core, 2 MB L2 per core, and 36 MB shared L3. It offers 16 PCIe Gen 5 lanes and includes UHD Graphics 770. It is a desktop part, released on 2023-10-16, and has an unlocked multiplier. The Intel part carries a launch MSRP of $589. Notably, the AMD has a higher base clock and more PCIe lanes, while the Intel has a higher boost clock, more cores, more L2 and L3 cache, and supports DDR4. The AMD's 4nm process and smaller die suggest better power efficiency, but the Intel's larger core count drives its benchmark dominance. The AMD also has a higher memory bandwidth figure (89.6 GB/s) while the Intel's is not listed, and both support ECC memory.
