Architecture Differences

Both processors share the Zen 5 architecture and the TSMC 4 nm process, but the similarity ends there. The AMD Ryzen AI 7 445 is a mobile part, coded Gorgon Point, belonging to the Ryzen AI 400 generation (Zen 5 / Zen 5c). It fits AMD Socket FP8 and is designed for the mobile market segment. The Threadripper 9980X, coded Shimada Peak, is a desktop part in the 9000 series, using AMD Socket sTR5.

The core configuration differs dramatically. The AI 7 445 packs 6 cores and 12 threads, while the Threadripper 9980X has 64 cores and 128 threads. That is a 10.7x core count advantage for the Threadripper. The cache hierarchy also diverges: the AI 7 445 has 80 KB L1 per core, 1 MB L2 per core, and 4 MB L3. The Threadripper 9980X has 64 KB L1 per core, 1 MB L2 per core, and 256 MB L3. The Threadripper's L3 is 64 times larger.

The physical construction is another major difference. The Threadripper 9980X is a multi-die design with 8 dies at 70.6 mm² each, totaling 66,520 million transistors. The database records no die size or transistor count for the AI 7 445, suggesting a monolithic or smaller package. The AI 7 445 includes a Radeon 840M integrated GPU; the Threadripper has none. The Threadripper is multiplier unlocked, while the AI 7 445 is locked.

Feature support also separates them. The AI 7 445 supports DDR5 and LPDDR5X memory on a dual-channel bus, with PCIe Gen 4 and 14 lanes (CPU only). The Threadripper supports DDR5 only, but on a quad-channel bus with 204.8 GB/s bandwidth, plus PCIe Gen 5 with 80 lanes (CPU only). Both have ECC memory support. The clock ranges differ as well: the AI 7 445 runs at 2.00 GHz base and 4.60 GHz boost, while the Threadripper runs at 3.20 GHz base and 5.40 GHz boost.

Where Each One Wins

The benchmark data shows a clean sweep: the Threadripper 9980X wins all 15 head-to-head tests, with winsB equal to 15 and winsA equal to 0. The AI 7 445 does not win any recorded benchmark. However, the two chips serve entirely different use cases based on their market segments and physical characteristics.

The AI 7 445 is a mobile processor in a 28 W TDP envelope. Its integrated Radeon 840M graphics and support for LPDDR5X memory make it suited for thin-and-light laptops where power draw and space are constrained. Its 6-core, 12-thread layout is enough for everyday productivity and light multithreaded work, and the 4.60 GHz boost clock keeps single-thread response snappy. The dual-channel memory bus and PCIe Gen 4 lanes (14 total) fit a mainstream mobile platform.

The Threadripper 9980X is a desktop workstation-class processor with a 350 W TDP. Its 64 cores and 128 threads are designed for heavily parallel workloads: rendering, scientific computing, data compression, and encryption. The 256 MB L3 cache and quad-channel memory bandwidth (204.8 GB/s) feed those cores effectively. The PCIe Gen 5 lanes (80 total) support high-throughput storage and multiple GPU configurations. The lack of integrated graphics is irrelevant in a workstation that will almost certainly use a discrete GPU.

The single-thread results show the closest contest. The Threadripper leads by only -20.9% in PassMark single-thread (4537 versus 3591) and by -86.3% in Cinebench R15 single-core (1857 versus 254). The Cinebench gap is larger, but the PassMark number indicates that the Threadripper's higher boost clock (5.40 GHz versus 4.60 GHz) gives it a real single-core edge, not just a core-count advantage. Still, the AI 7 445's single-core score of 3591 in PassMark is competitive for a mobile chip, while the Threadripper's 4537 is exceptional for any desktop part.

The specification table shows the two chips occupy opposite ends of the market. The AI 7 445 is a low-power mobile part with integrated graphics and a modest memory bus. The Threadripper 9980X is a high-power desktop part with massive core count, enormous L3 cache, quad-channel memory, and PCIe Gen 5. Both use Zen 5 and TSMC 4 nm, but the Threadripper's 8-die design with 66,520 million transistors dwarfs the AI 7 445's package.

Note that the AI 7 445 has a later release date (2026-01-04) than the Threadripper (2025-07-29), and the Threadripper has a recorded launch MSRP of $4999 while the AI 7 445 has no MSRP in the database.

Head-to-Head Benchmarks

The Threadripper 9980X dominates every recorded benchmark against the AI 7 445. The largest margins appear in multithreaded and data-heavy workloads. In Cinebench R23 multicore, the Threadripper scores 130529 versus 10590, a delta of -91.9%. That means the AI 7 445 delivers less than one-tenth of the Threadripper's multicore rendering performance. Cinebench R15 multicore tells a similar story: 13157 versus 1723, a -86.9% delta.

The PassMark suite shows consistent gaps across all sub-tests. In integer math, the Threadripper scores 872071 against 58332, a -93.3% delta. Floating point math follows at 559003 versus 39362, a -93% delta. Data encryption shows 157137 versus 10519, also -93.3%. Data compression is 2974534 versus 215812, a -92.7% delta. Extended instructions: 228959 versus 15826, -93.1%. Random string sorting: 292083 versus 23488, -92%. Find prime numbers: 769 versus 56, -92.7%. The PassMark multithread score is 141641 versus 18115, a -87.2% delta, and physics is 8001 versus 976, a -87.8% delta.

The single-thread tests show the smallest deltas, but the Threadripper still leads. In PassMark single-thread, the Threadripper scores 4537 versus 3591, a -20.9% delta. This is the closest contest in the entire dataset, indicating that the AI 7 445's Zen 5 cores are competitive on a per-thread basis. Cinebench R23 single-core shows 18427 versus 1806, a -90.2% delta, which is a much larger gap than the PassMark number. Cinebench R15 single-core is 1857 versus 254, a -86.3% delta.

The pattern is clear: the Threadripper 9980X is in a different performance class, especially in multithreaded workloads where its 64 cores and 128 threads can be fully utilized. The AI 7 445's best showing is in single-thread PassMark, where it trails by only about 21%, but the Threadripper's higher boost clock and desktop power budget give it the edge everywhere. The AI 7 445's 15 recorded benchmark losses are all to a processor with 10.7x more cores, 64x more L3 cache, and more than double the memory bandwidth.
