AMD Ryzen AI 7 445 vs AMD Ryzen Threadripper 9970X Comparison

Head-to-Head Benchmarks

The recorded data shows a complete sweep: the AMD Ryzen Threadripper 9970X wins all 11 shared benchmark comparisons. The largest margin appears in the prime number test, where the Threadripper scores 615 versus 56 for the Ryzen AI 7 445, a delta of -90.9% from the mobile chip's perspective. This workload, which stresses integer iteration and branch prediction, scales almost linearly with core count, and the Threadripper's 32 cores overwhelm the 6-core Ryzen AI part.

Data compression shows a similar story. The Threadripper posts 1,757,998 points against 215,812 for the Ryzen AI 7 445, a -87.7% delta. That means the desktop processor delivers roughly 8.1 times the compression throughput. Encryption follows at -87.9% (86,765 versus 10,519), and extended instruction throughput sits at -88.9% (142,342 versus 15,826). These three workloads all benefit from the Threadripper's wider memory path and higher core count, not just raw clock speed.

Floating-point math shows a -87.3% delta (309,719 versus 39,362), while integer math lands at -87.5% (465,378 versus 58,332). The multithread benchmark narrows the gap slightly to -83.1% (107,399 versus 18,115), suggesting that thread scheduling overhead and memory latency play a role at scale. Physics simulation, which often rewards both core count and cache capacity, shows -85.7% (6,835 versus 976). Random string sorting, a memory-bandwidth-sensitive test, matches the compression delta at -87.7% (191,445 versus 23,488).

The closest relative gap is in single-thread performance. The Threadripper scores 4,530 against 3,591 for the Ryzen AI 7 445, a -20.7% delta. This is the only metric where the mobile chip comes within striking distance, reflecting the fact that both processors share the Zen 5 architecture and the Threadripper's 5.40 GHz boost clock exceeds the Ryzen AI's 4.60 GHz boost. Still, a 20.7% single-thread deficit is meaningful for lightly threaded applications, but it does not compensate for the 5.9 times core-count advantage in heavily parallel work.

Architecture Differences

Both processors use TSMC's 4 nm process node and the Zen 5 microarchitecture, but their physical and logical layouts diverge sharply. The Ryzen AI 7 445 uses the Gorgon Point codename and belongs to the Ryzen AI 400 generation, which mixes Zen 5 and Zen 5c cores. It has 6 cores and 12 threads, with a base clock of 2.00 GHz and a boost clock of 4.60 GHz. The Threadripper 9970X uses the Shimada Peak codename, sits in the 9000 series, and has 32 cores and 64 threads, with a base clock of 4.00 GHz and a boost clock of 5.40 GHz.

Cache organization differs substantially. The Ryzen AI 7 445 has 80 KB of L1 per core, 1 MB of L2 per core, and only 4 MB of shared L3. The Threadripper 9970X has 64 KB of L1 per core, 1 MB of L2 per core, and 128 MB of L3. That 32 times difference in L3 capacity is a decisive factor for workloads with large working sets, such as video encoding, scientific simulation, and database queries. The Threadripper also reports 33,260 million transistors across 4x 70.6 mm² dies, while the Ryzen AI 7 445 does not report transistor or die size data.

Memory interfaces diverge as well. The Ryzen AI 7 445 supports DDR5 and LPDDR5X over a dual-channel bus, yielding 89.6 GB/s of bandwidth. The Threadripper 9970X supports DDR5 over a quad-channel bus, yielding 204.8 GB/s. That 2.3 times bandwidth advantage explains why memory-bound tests like random string sorting show such large deltas. Both support ECC memory, but the Threadripper's PCIe implementation is Gen 5 with 80 lanes, while the Ryzen AI 7 445 uses Gen 4 with 14 lanes. The Threadripper also has an unlocked multiplier, whereas the Ryzen AI 7 445 does not.

Integrated graphics separate the two completely. The Ryzen AI 7 445 includes a Radeon 840M, making it a self-contained mobile processor. The Threadripper 9970X has no integrated graphics, requiring a discrete GPU. Socket and market segment also differ: the Ryzen AI 7 445 uses AMD Socket FP8 and targets mobile systems, while the Threadripper 9970X uses AMD Socket sTR5 and targets desktop workstations.

The Verdict

The benchmark data indicates two processors with opposite design goals. The AMD Ryzen AI 7 445 delivers a 79th percentile standing among all CPUs, with an average benchmark score of 26,936. It competes closely with the Intel Core i7-1370P (delta +0.1%), the AMD Ryzen 5 7545U (delta +0.3%), the AMD Ryzen 7 5700G (delta -0.4%), and the Intel Core i9-9900K (delta -0.6%). This places it firmly in the upper-midrange mobile segment, where its 6 cores and 12 threads, combined with the Radeon 840M integrated graphics and 28 W TDP, suit thin-and-light laptops that need solid all-round performance without discrete graphics.

The AMD Ryzen Threadripper 9970X sits at the 99th percentile, with an average benchmark score of 279,778. Its nearest rivals are the Intel Xeon 6780E (delta -0.2%), the AMD EPYC 9565 (delta -2%), the Intel Xeon 696X (delta -2.2%), and the AMD EPYC 9555P (delta -2.5%). The Threadripper's 32 cores, 64 threads, 128 MB L3, and quad-channel DDR5 with 204.8 GB/s bandwidth make it a workstation-class part for rendering, simulation, and data processing. The launch MSRP for the Threadripper is $2499, and it requires discrete graphics.

The data shows no scenario where the Ryzen AI 7 445 outperforms the Threadripper in the shared benchmarks. The closest margin is single-thread performance, where the Threadripper leads by 20.7%. For users who need maximum parallel throughput, the Threadripper 9970X is the clear choice. For users who need a mobile processor with integrated graphics and modest power consumption, the Ryzen AI 7 445 fits that role, but it cannot match the Threadripper's absolute performance in any measured workload. The choice depends entirely on the target system form factor and workload scale, not on benchmark headroom.
