Architecture Differences

Both chips use Zen 5 cores and TSMC's 4 nm process, but the platform split is substantial. The Ryzen 7 9800X3D is a Granite Ridge desktop chip with 8 cores and 16 threads. The Ryzen AI 5 PRO 435 is a Gorgon Point mobile chip with 6 cores and 12 threads. The database records the mobile generation as "Ryzen AI PRO 400 (Zen 5 / Zen 5c)", indicating a mix of Zen 5 and Zen 5c cores, while the desktop generation is listed as "Ryzen 7 (Zen 5 (Granite Ridge))".

Cache is the most pronounced architectural difference. The desktop part carries 96 MB of shared L3 cache, while the mobile part has 4 MB of L3. Both use 80 KB L1 and 1 MB L2 per core, so the L3 capacity gap is the main separation at the cache level. The desktop chip also has a much higher clock envelope: 4.70 GHz base and 5.20 GHz boost, compared with 2.00 GHz base and 4.50 GHz boost for the mobile part.

The desktop chip uses AMD Socket AM5, has a 120 W TDP, PCIe Gen 5 with 24 lanes, and an unlocked multiplier. The mobile chip uses AMD Socket FP8, has a 28 W TDP, PCIe Gen 4 with 14 lanes, and a locked multiplier. The 9800X3D lists Radeon Graphics as its integrated GPU, while the Ryzen AI 5 PRO 435 lists Radeon 840M. Memory support also differs: the desktop part is DDR5 only, while the mobile part supports DDR5 and LPDDR5X. Both have dual-channel memory buses and 89.6 GB/s bandwidth, and both support ECC memory. The desktop die is recorded at 70.6 mm² with 8,315 million transistors; the mobile part's die size and transistor count are not recorded.

The Verdict

The recorded data points to a clear split. The Ryzen 7 9800X3D is the higher-performance processor in every recorded benchmark: it wins all 11 head-to-head tests, holds a 39768 average benchmark score against 37762, and ranks at the 87th percentile versus the 86th. Its nearest rivals in the database include the Ryzen 7 7700 at 40081, a 0.8% gap, and the Ryzen AI 9 365 at 40048, a 0.7% gap, placing it in a strong performance band.

The Ryzen AI 5 PRO 435 is the lower-power mobile part. Its 28 W TDP, FP8 socket, and LPDDR5X support are the traits that distinguish it. Its nearest rivals include the Intel Core i5-13600K at 37685, a 0.2% gap, and the AMD Ryzen AI 9 HX 370 at 37904, a 0.4% gap. No benchmark in the head-to-head set favors it, so its selection case is platform-driven rather than performance-driven.

For workloads measured by the database, the 9800X3D is the part for performance-first desktop systems where multithreading, single-thread speed, and compute density are the priority. The Ryzen AI 5 PRO 435 is the part for a mobile platform where the 28 W TDP, LPDDR5X memory support, and Radeon 840M graphics are the deciding factors.

| passmark_singlethread | 4430 | 3757 | 17.9% |

The largest single gap is in prime number search: 423 versus 57, a 642.1% delta. The smallest gap is single-thread performance, where the 9800X3D leads 4430 to 3757, a 17.9% advantage. In between, multithread performance is 109.6% higher, data compression is 101% higher, extended instructions are 132% higher, and physics is 310.4% higher. The mobile part's closest result is still the single-thread test, and even there it trails by a wide margin.

Where Each One Wins

Based solely on recorded head-to-head results, the Ryzen 7 9800X3D wins every compute category: data compression, encryption, extended instructions, prime number search, floating-point math, integer math, multithread, physics, random string sorting, and single-thread performance. Its largest wins are in prime number search and physics, indicating a strong advantage in branching and simulation-style calculations. The multithread and data compression wins are also large, at 109.6% and 101%, respectively.

The Ryzen AI 5 PRO 435 does not win any recorded benchmark, so its use case is defined by platform characteristics instead. It is a mobile part with a 28 W TDP, an FP8 socket, DDR5 and LPDDR5X memory support, and Radeon 840M integrated graphics. In the database's nearest-rival comparison, it sits within 0.4% of the AMD Ryzen AI 9 HX 370, so it occupies a competitive mobile performance band even though it loses the head-to-head comparison to the desktop chip.

The use-case split is therefore clear: the 9800X3D for benchmark-defined compute performance, and the Ryzen AI 5 PRO 435 for low-power mobile systems where the 28 W TDP and LPDDR5X support matter more than head-to-head benchmark victories.
