AMD Ryzen 7 PRO 5755G vs AMD Ryzen AI 5 430 Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive overall victory for the AMD Ryzen 7 PRO 5755G in the PassMark suite, winning 9 out of 11 head-to-head comparisons. The most lopsided result appears in data encryption, where the Ryzen 7 PRO 5755G scores 19,450 against 7,591 for the Ryzen AI 5 430, a delta of 156.2%. This is the largest performance gap in the entire comparison, indicating a massive advantage in cryptographic workloads for the desktop part.

Integer math follows a similar pattern, with the Ryzen 7 PRO 5755G posting 90,270 versus 39,637 for the Ryzen AI 5 430, a 127.7% advantage. Random string sorting is also heavily one-sided: 32,771 against 16,623, a 97.1% delta. These results suggest that the Ryzen 7 PRO 5755G’s eight cores and sixteen threads provide substantial throughput in parallel integer-heavy tasks, whereas the Ryzen AI 5 430, with four cores and eight threads, trails by a wide margin.

Floating point math shows an 86.7% lead for the Ryzen 7 PRO 5755G, with scores of 50,778 versus 27,193. Data compression is similarly lopsided at 86.1%, with 295,730 against 158,912. Extended instructions deliver a 78.8% advantage for the Ryzen 7 PRO 5755G, scoring 20,487 versus 11,455. The multithread benchmark reinforces this trend: 23,858 for the desktop chip versus 13,320 for the mobile chip, a 79.1% delta. Physics tests show a 40.8% lead for the Ryzen 7 PRO 5755G (1,022 versus 726), and prime number finding favors it by 31.8% (58 versus 44).

The lone bright spot for the AMD Ryzen AI 5 430 is single-thread performance. In the PassMark single-thread test, it scores 3,683 against 3,366 for the Ryzen 7 PRO 5755G, a delta of -8.6% from the perspective of the desktop chip. That is a modest but consistent win, appearing in both single-thread entries in the database. The newer Zen 5-based mobile part clearly has an edge per-core clock-for-clock, but it cannot overcome the core-count deficit in heavily multithreaded scenarios.

The average benchmark score further contextualizes the gap: the Ryzen 7 PRO 5755G averages 49,196, while the Ryzen AI 5 430 averages 19,617. The desktop chip sits in the 90th percentile of all CPUs in the database, whereas the mobile chip is in the 73rd percentile. The nearest rivals for the Ryzen 7 PRO 5755G include the AMD Ryzen 9 7900 (avg score 49,228, delta -0.1%), Intel Core i5-14600KF (49,394, delta -0.4%), Intel Core Ultra 5 245 (48,995, delta 0.4%), and Intel Xeon Gold 5318H (48,698, delta 1%). For the Ryzen AI 5 430, the nearest rivals are the AMD Ryzen 5 5500 (19,593, delta 0.1%), Intel Core i5-12500 (19,668, delta -0.3%), Intel Core i5-11600KF (19,723, delta -0.5%), and Intel Core i7-10700F (19,499, delta 0.6%). These figures show that each chip is competitive within its own performance tier, but the tiers themselves are far apart.

The Verdict

The data is unambiguous for workloads that scale with core count. The AMD Ryzen 7 PRO 5755G is the superior processor for multithreaded computation, offering leads ranging from 31.8% to 156.2% across every parallel benchmark in the comparison. Its eight cores, sixteen threads, and 16 MB of L3 cache deliver throughput that the four-core, eight-thread Ryzen AI 5 430 cannot approach. The desktop chip’s 65-watt TDP supports sustained high clocks, and its 3.80 GHz base and 4.60 GHz boost clocks are substantially higher than the mobile part’s 2.00 GHz base and 4.50 GHz boost, which explains much of the performance delta.

The AMD Ryzen AI 5 430, by contrast, should be selected when single-thread responsiveness is the priority. Its 3,683 single-thread score is 8.6% ahead of the Ryzen 7 PRO 5755G, and its 4 nm process node, Zen 5 architecture, and support for DDR5 and LPDDR5X memory give it a modern feature set that the older Zen 3 part lacks. The mobile chip also supports ECC memory, a feature absent from the Ryzen 7 PRO 5755G, and its 28-watt TDP makes it suitable for power-constrained designs. However, the database shows its average score at 19,617, which places it in the same performance class as desktop parts like the Ryzen 5 5500 and Core i5-12500, not in the class of the Ryzen 7 PRO 5755G.

For a desktop system where raw compute throughput is the goal, the Ryzen 7 PRO 5755G is the clear choice. For a mobile platform where single-thread speed and energy efficiency matter more, the Ryzen AI 5 430 has a defined role. The data does not suggest that one chip replaces the other; it suggests that they serve different segments.

Specification Differences

The two processors differ in nearly every core specification. The Ryzen 7 PRO 5755G has 8 cores and 16 threads, while the Ryzen AI 5 430 has 4 cores and 8 threads. Base clocks are far apart: 3.80 GHz for the desktop chip versus 2.00 GHz for the mobile chip. Boost clocks are closer, at 4.60 GHz versus 4.50 GHz. TDP is 65 watts for the Ryzen 7 PRO 5755G and 28 watts for the Ryzen AI 5 430.

Cache configurations diverge significantly. The Ryzen 7 PRO 5755G uses 64 KB L1 per core, 512 KB L2 per core, and 16 MB L3. The Ryzen AI 5 430 uses 80 KB L1 per core, 1 MB L2 per core, and only 4 MB L3. Memory support differs as well: the desktop chip uses DDR4 with a dual-channel bus and 51.2 GB/s bandwidth, while the mobile chip uses DDR5 and LPDDR5X with a dual-channel bus and 89.6 GB/s bandwidth. ECC memory is absent on the Ryzen 7 PRO 5755G but present on the Ryzen AI 5 430.

PCIe connectivity is another differentiator. The Ryzen 7 PRO 5755G supports PCIe Gen 3 with 16 lanes (CPU only), while the Ryzen AI 5 430 supports PCIe Gen 4 with 14 lanes (CPU only). Integrated graphics differ: the desktop chip uses Radeon Vega 8, and the mobile chip uses Radeon 840M. Sockets are incompatible: AMD Socket AM4 versus AMD Socket FP8. The market segments are Desktop versus Mobile, respectively.

Architecture Differences

The architecture gap reflects a generational shift. The Ryzen 7 PRO 5755G is built on Zen 3 with the codename Cezanne, part of the 5000 series and the Ryzen 7 generation. It uses a 7 nm process node from TSMC, with 10,700 million transistors and a die size of 180 mm². The Ryzen AI 5 430 uses Zen 5 / Zen 5c architecture under the codename Gorgon Point, part of the Ryzen AI 400 generation. It is manufactured on a 4 nm node from TSMC, though the database does not list its transistor count or die size.

The cache hierarchy reflects the architectural change. The Ryzen 7 PRO 5755G allocates 64 KB L1 per core and 512 KB L2 per core, whereas the Ryzen AI 5 430 allocates 80 KB L1 per core and 1 MB L2 per core. However, the desktop chip’s L3 is 16 MB, four times the 4 MB L3 of the mobile chip. The mobile part’s higher per-core L1 and L2 capacities likely contribute to its single-thread advantage, while the desktop chip’s larger L3 and core count drive its multithreaded lead.

Other architectural features include the process node, which directly affects efficiency: the 4 nm node of the Ryzen AI 5 430 supports a 28-watt TDP, whereas the 7 nm node of the Ryzen 7 PRO 5755G requires 65 watts. The mobile chip also enables newer memory technology (DDR5, LPDDR5X) and a higher memory bandwidth of 89.6 GB/s, compared to DDR4 and 51.2 GB/s for the desktop part. The Ryzen AI 5 430 adds ECC support, and its PCIe Gen 4 interface offers double the bandwidth per lane of the Ryzen 7 PRO 5755G’s PCIe Gen 3. The integrated GPU also changes from Radeon Vega 8 to Radeon 840M, reflecting the newer mobile platform. Both processors are listed as Active in production status, with the Ryzen 7 PRO 5755G released on September 4, 2024, and the Ryzen AI 5 430 released on January 4, 2026.
