AMD Ryzen 7 PRO 5845

The AMD Ryzen 7 PRO 5845 is an 8-core, 16-thread desktop processor built on the Zen 3 architecture, codenamed Vermeer, and manufactured on TSMC's 7nm process. It runs at a 3.40 GHz base clock and boosts to 4.60 GHz, with a 65W TDP. In the benchmark database, it holds an average score of 35802, placing it in the 89th percentile of all CPUs. This professional-grade chip targets workstations and reliability-focused builds, offering ECC memory support and a locked multiplier.

How It Compares

Against the Intel Core i7-12700K, the Ryzen 7 PRO 5845 posts an average benchmark score of 35802 versus 35684, a 0.3% advantage. This margin is negligible in real-world terms, but it does mean the Ryzen edges ahead of a popular enthusiast chip. The i7-12700K is a well-known high-performance desktop processor, yet the PRO 5845 manages to outpace it in aggregate scores.

The Intel Core i5-14500HX, with an average score of 35940, leads the Ryzen by 0.4%. The deltaPct of -0.4 indicates that the Ryzen is slightly slower, though the difference is within typical run-to-run variance. This rival is a mobile-oriented HX part, yet it still holds a small edge over the desktop PRO chip in overall performance.

The AMD Ryzen 7 9700X scores 36029, making it 0.6% faster than the PRO 5845. This is the largest deficit among the listed rivals, but again the gap is small. Both are AMD Zen-based parts, and the 9700X's newer architecture likely contributes to its slight lead. Still, the PRO 5845 remains within a rounding error of this competitor.

Finally, the Intel Core i7-13700T trails with an average of 35468, giving the Ryzen a 0.9% lead. This is the widest margin in either direction, showing that the PRO 5845 comfortably outperforms that particular Intel part. The i7-13700T is a low-power desktop chip, and the data shows the Ryzen holds a clear advantage in aggregate performance.

Platform and Compatibility

The Ryzen 7 PRO 5845 uses the AMD Socket AM4, a long-lived platform that supports a wide range of motherboards. It supports dual-channel DDR4 memory with a bandwidth of 51.2 GB/s. ECC memory is supported, making it suitable for workstation or server-like reliability where data integrity is critical. The processor provides PCIe Gen 4 with 20 lanes from the CPU, which is ample for a high-end GPU and NVMe drives.

The chip is based on the Zen 3 architecture, codenamed Vermeer, and is manufactured on TSMC's 7nm process. It contains 4,150 million transistors on a 74 mm² die. The processor was released on April 3, 2022, and remains in active production. Notably, it does not have integrated graphics, so a discrete GPU is required. The multiplier is locked, meaning overclocking is not supported; this aligns with its PRO positioning, which prioritizes stability over enthusiast tuning.

Benchmark Performance

The Ryzen 7 PRO 5845 delivers strong multi-threaded performance. In Cinebench R23, it scores 22145 points in the multi-core test and 3126 in single-core. The R20 results are 9300 multi-core and 1312 single-core, while R15 shows 2232 multi-core and 314 single-core. These numbers indicate a balanced architecture that scales well across workloads, from rendering to compilation.

In Passmark tests, the processor achieves a multithread score of 26054 and a single-thread score of 3442. Integer math reaches 94884, while floating-point math hits 52105. Data compression scores 314363, encryption 19815, extended instructions 21117, and random string sorting 33754. The physics test yields 1109, and finding prime numbers scores 115. These results show a CPU that excels in compute-heavy tasks, with particularly strong integer and floating-point throughput.

The average benchmark score of 35802 places the Ryzen 7 PRO 5845 in the 89th percentile of all CPUs. This means it outperforms 89% of processors in the database. Compared to its nearest rivals, the differences are minimal: it is 0.3% ahead of the i7-12700K, 0.4% behind the i5-14500HX, 0.6% behind the Ryzen 7 9700X, and 0.9% ahead of the i7-13700T. These margins are within the noise of typical benchmarking, suggesting that the PRO 5845 is effectively on par with those parts in overall performance.

Power and Thermals

The Ryzen 7 PRO 5845 has a TDP of 65W, which is a modest power envelope for an 8-core processor. This suggests that it can be cooled by a standard air cooler or a compact liquid cooler, though the exact cooler requirements are not specified. The 7nm process node contributes to efficiency, and the chip's locked multiplier means it will run at stock settings. With a 65W TDP, it is well-suited for small form factor builds or office workstations where heat output is a concern. The lack of integrated graphics also reduces overall system power draw, as a discrete GPU is necessary. This power profile, combined with its ECC support and AM4 compatibility, makes it a dependable choice for professional environments that prioritize stability over peak performance.
