Architecture Differences

The two processors diverge sharply at the architectural level. The 7700X is a Zen 4 part, codenamed Raphael, built on a 5 nm process at TSMC with 6,570 million transistors on a 71 mm² die. In contrast, the PRO 5845 is a Zen 3 part, codenamed Vermeer, using a 7 nm process with 4,150 million transistors on a slightly larger 74 mm² die. The node advantage gives the 7700X a denser, more power-efficient design, though both chips have 8 cores and 16 threads.

Cache organization differs as well. Both share 64 KB of L1 cache per core and 32 MB of shared L3 cache, but the L2 cache is different: the 7700X has 1 MB per core, while the PRO 5845 has only 512 KB per core. This doubling of L2 cache on the 7700X can benefit workloads with high per-thread data reuse. Neither chip features 3D V-Cache.

Platform support also separates them. The 7700X uses the AMD Socket AM5 and supports PCIe Gen 5 with 24 CPU lanes, while the PRO 5845 uses the older AMD Socket AM4 with PCIe Gen 4 and 20 lanes. The 7700X includes integrated Radeon Graphics, whereas the PRO 5845 has no integrated graphics. The memory interface follows suit: DDR5 for the 7700X and DDR4 for the PRO 5845, with memory bandwidth of 83.2 GB/s versus 51.2 GB/s respectively. Both support ECC memory and are desktop parts.

Clock speeds are notably different. The 7700X runs at a 4.50 GHz base and 5.40 GHz boost, while the PRO 5845 operates at a 3.40 GHz base and 4.60 GHz boost. The 7700X also has a higher TDP of 105 watts versus 65 watts for the PRO 5845. The 7700X has an unlocked multiplier; the PRO 5845 is locked. These architectural differences explain why the 7700X generally leads in raw throughput, while the PRO 5845’s lower power draw and older platform appeal to specific use cases.

Head-to-Head Benchmarks

The head-to-head results show a clear pattern: the 7700X dominates in most computational tasks, while the PRO 5845 wins in two Cinebench scenarios. The 7700X secures 13 wins out of 15 tests, with its largest margin in PassMark physics at 81% (2007 vs 1109). It also posts a 56.5% lead in PassMark find prime numbers (180 vs 115) and a 51.7% advantage in PassMark extended instructions (32033 vs 21117). Other substantial wins include 47.5% in random string sorting (49782 vs 33754) and 39.5% in Cinebench R15 multi-core (3113.5 vs 2232).

In PassMark multi-thread performance, the 7700X scores 35686 against 26054, a 37% lead. Data compression shows a 33.7% edge (420240 vs 314363), and floating-point math is 32.4% higher (68986 vs 52105). The 7700X also wins PassMark single-thread by 21.7% (4190 vs 3442) and integer math by 18.7% (112601 vs 94884). Data encryption shows a 24.8% advantage (24732 vs 19815). Even the closest 7700X win, Cinebench R15 single-core, is 0.3% (315 vs 314).

The PRO 5845’s two victories are more dramatic. In Cinebench R23 multi-core, it scores 22145 versus 19088, a 13.8% margin in its favor. The bigger surprise is Cinebench R23 single-core, where the PRO 5845 scores 3126 against 1987, a 36.4% lead for the older chip. These results suggest that the PRO 5845’s higher single-core Cinebench score is anomalous relative to its other benchmark results, which consistently trail the 7700X. The data indicates that while the PRO 5845 can excel in specific rendering workloads, the 7700X is the stronger all-around performer across the broader benchmark suite.

Specification Differences

The specification sheets reveal a wide gap between the two chips. The 7700X has a base clock of 4.50 GHz and a boost clock of 5.40 GHz; the PRO 5845 sits at 3.40 GHz base and 4.60 GHz boost. TDP is 105 watts for the 7700X and 65 watts for the PRO 5845. The socket changes from AM5 on the 7700X to AM4 on the PRO 5845. The process node is 5 nm versus 7 nm, with transistor counts of 6,570 million and 4,150 million respectively. Die size is 71 mm² for the 7700X and 74 mm² for the PRO 5845.

Memory support is a key differentiator: DDR5 for the 7700X and DDR4 for the PRO 5845, with memory bandwidth of 83.2 GB/s versus 51.2 GB/s. PCIe generation and lanes differ as well: Gen 5 with 24 lanes on the 7700X versus Gen 4 with 20 lanes on the PRO 5845. The 7700X includes integrated Radeon Graphics, while the PRO 5845 has none. The 7700X has an unlocked multiplier, but the PRO 5845 is locked. The L2 cache is 1 MB per core on the 7700X versus 512 KB per core on the PRO 5845.

Release dates differ, with the 7700X launching on 2022-09-26 and the PRO 5845 on 2022-04-03. The 7700X has a launch MSRP of $399; the PRO 5845 has no listed launch MSRP. Part numbers are 100-000000591 for the 7700X and 100-000000832 for the PRO 5845. The series and codenames are also distinct: 7000 series (Raphael) versus 5000 series (Vermeer). Both chips have 8 cores, 16 threads, 64 KB L1 cache per core, 32 MB shared L3 cache, dual-channel memory buses, and ECC support.

Where Each One Wins

The AMD Ryzen 7 7700X is the clear winner for users prioritizing maximum performance across a broad range of compute tasks. Its 81% lead in PassMark physics makes it the better choice for simulation and physics-heavy applications. The 56.5% advantage in find prime numbers and 51.7% in extended instructions suggests strong integer and vectorized workloads. For data compression and encryption, the 7700X offers 33.7% and 24.8% gains respectively, making it ideal for database, archive, or security-related tasks. Its 37% lead in PassMark multi-thread and 21.7% in single-thread performance means it handles both heavily threaded and lightly threaded software effectively. The 7700X also benefits from DDR5 memory support, higher bandwidth (83.2 GB/s), and a newer PCIe Gen 5 interface, which future-proofs it for next-generation storage and graphics.

The AMD Ryzen 7 PRO 5845 wins in two specific Cinebench tests, which makes it interesting for rendering workloads that rely on Cinebench’s scoring methodology. Its 13.8% multi-core lead in Cinebench R23 (22145 vs 19088) is notable, but the 36.4% single-core advantage in the same suite is the standout result. For users running applications that mirror Cinebench R23’s rendering engine, the PRO 5845 could deliver faster performance per core. Additionally, its 65-watt TDP is substantially lower than the 7700X’s 105 watts, making it a better fit for power-constrained or thermally limited systems. The PRO 5845 also uses the AM4 platform, which may be a lower-cost upgrade path for existing AM4 motherboard owners, though pricing information is not available for this comparison. The integrated Radeon Graphics on the 7700X is a distinct advantage for systems without a discrete GPU, whereas the PRO 5845 requires a separate graphics card. In summary, the 7700X is the superior performer in most benchmarks, while the PRO 5845 offers a power-efficient alternative with specific rendering strengths.
