AMD Ryzen 9 PRO 7945

The AMD Ryzen 9 PRO 7945 is a 12-core, 24-thread Zen 4 processor in the Raphael family, built on TSMC's 5 nm process for the AMD Socket AM5 platform. It is classified in the Server/Workstation market segment, carries a 65 W TDP, and posts an average benchmark score of 11469. That score places it at the 71st percentile of all CPUs in the database and inside a tight cluster of nearest rivals whose aggregate scores differ by no more than 1.4%.

How It Compares

The nearest rival by average benchmark score is the Intel Core i7-4790. The Ryzen 9 PRO 7945 scores 11469 against the i7-4790's 11499, a delta of -0.3%. In aggregate terms, the two parts are effectively tied; the Ryzen is nominally behind, but the margin is small enough that the ordering carries little practical weight.

Against the Intel Xeon Gold 6342, the Ryzen's 11469 trails the rival's 11574 by -0.9%. This is again a narrow margin, and it places the Ryzen just behind the Xeon in the aggregate ranking. The gap is still less than a full percentage point, so the two chips occupy the same general performance band.

The AMD EPYC 73F3 sits below the Ryzen in this group. The EPYC averages 11334, giving the Ryzen a +1.2% lead. This is a modest advantage, but it puts the Ryzen on the positive side of the comparison.

The AMD EPYC 7402 averages 11312, and the Ryzen leads it by +1.4%, the largest positive delta in the nearest-rival set. Even so, the margin is small in absolute terms. Across all four nearest rivals, the Ryzen 9 PRO 7945 sits roughly in the middle: just behind the two Intel parts and just ahead of the two AMD EPYC parts.

Power and Thermals

The 65 W TDP is the central thermal specification for this processor. For a 12-core, 24-thread chip with a 3.70 GHz base clock and a 5.40 GHz boost clock, that is a modest power envelope. The 5 nm process from TSMC is a likely contributor to this behavior, as is the 2x 71 mm² die configuration containing 13,140 million transistors.

Cooling requirements follow from the TDP class. A 65 W part does not demand an exotic thermal solution; the data implies that a capable air cooler is a reasonable fit for sustained workloads. The integrated Radeon Graphics unit also provides a display path on the processor itself, which can simplify low-power system builds and reduce the need for a separate GPU in basic configurations.

The multiplier is not unlocked, so this processor is not positioned for heavy manual overclocking. The 65 W class is also relevant in systems where power density and heat removal are constraints, which fits the Server/Workstation segment. Memory support is DDR5 on a dual-channel bus with 83.2 GB/s bandwidth, and ECC memory is enabled, making the platform more aligned with professional workloads than with enthusiast desktop builds.

Benchmark Performance

The aggregate benchmark score is 11469. Relative to nearest rivals, the Ryzen 9 PRO 7945 is 0.3% behind the Intel Core i7-4790, 0.9% behind the Intel Xeon Gold 6342, 1.2% ahead of the AMD EPYC 73F3, and 1.4% ahead of the AMD EPYC 7402. The corresponding rival average scores are 11499, 11574, 11334, and 11312 respectively.

In Cinebench, the results are:

| Test | Multi-core | Single-core |

| --- | --- | --- |

| Cinebench R15 | 3996 | 564 |

| Cinebench R20 | 16654 | 2351 |

| Cinebench R23 | 39653 | 5598 |

The multi-core scores dominate the profile. Cinebench R23 multi-core of 39653 and R20 multi-core of 16654 indicate strong throughput when all 24 threads are active. The Cinebench R15 multi-core result of 3996 follows the same direction. These results are consistent with a 12-core Zen 4 design that scales well across its full thread count.

Single-core performance is also strong. The R23 single-core score of 5598, R20 single-core score of 2351, and R15 single-core score of 564 show that lightly threaded tasks receive a meaningful boost from the 5.40 GHz boost clock. This combination of solid multi-core and single-core results explains why the aggregate score lands in a cluster with both Intel and AMD parts: the processor does not lead by a wide margin, but it stays competitive across different workload shapes.

The 71st percentile ranking shows that the Ryzen 9 PRO 7945 outperforms the majority of all CPUs in the database. At the same time, the nearest-rival deltas are all within a narrow range, meaning this chip is not an outlier in its performance band. The 64 MB shared L3 cache, 24 PCIe Gen 5 lanes, and DDR5 dual-channel memory path round out the platform-level picture.

Who Should Consider It

Users running multi-threaded creation or engineering workloads have a clear reason to consider this processor. The Cinebench R23 multi-core score of 39653 and R20 multi-core score of 16654 show that rendering, encoding, and compute tasks built around 24 threads can map directly onto the 12 physical cores. The 65 W TDP makes such workloads less thermally demanding than many higher-power workstation parts.

Office and productivity users should look at the single-core results. The R23 single-core score of 5598 and R20 single-core score of 2351 indicate strong per-thread responsiveness for everyday software. The integrated Radeon Graphics unit means a basic display output is available without a discrete GPU, which can be useful for simple workstation configurations.

Memory-sensitive workloads also fit this part's profile. ECC support is enabled, memory support is DDR5, and the dual-channel bus delivers 83.2 GB/s of bandwidth. That combination is relevant for systems where data integrity matters more than raw gaming throughput. The 64 MB shared L3 cache and 24 PCIe Gen 5 lanes add further server/workstation context.

This is not an enthusiast overclocking part. The multiplier is locked, and the Server/Workstation segment classification points toward stable, out-of-box deployment rather than tuning-focused use. Gamers may notice the strong single-core scores, but the benchmark data includes no game-specific metrics, and the professional market positioning should be considered before treating this as a consumer gaming chip.
