AMD Ryzen AI Embedded P174i vs AMD Ryzen Threadripper 9980X Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark results between the AMD Ryzen AI Embedded P174i and the AMD Ryzen Threadripper 9980X. The database shows that the Ryzen AI Embedded P174i has an empty benchmark array, meaning no individual test scores have been captured for that processor. In contrast, the Ryzen Threadripper 9980X has 17 recorded benchmark scores across Cinebench and Passmark workloads.

For the Threadripper 9980X, the Cinebench R23 multicore score of 130529 places it in the top percentile of all CPUs, with a percentile rank of 99. Its single-core Cinebench R23 score of 18427 indicates strong per-thread performance for a 64-core part. The Passmark multithread score of 141641 and the Passmark single-thread score of 4537 confirm that this processor delivers high throughput in both heavily parallel and lightly threaded tasks.

Because the Ryzen AI Embedded P174i lacks recorded benchmark scores, the database cannot assign it a comparable average benchmark score. Its percentile vs all CPUs is 50, which represents the median of the database, but this value is not derived from actual test results. The Threadripper 9980X, with an average benchmark score of 321753, sits far above that median point.

The nearest rivals for the Threadripper 9980X provide context for its standing. The AMD Ryzen Threadripper PRO 9985WX averages 320749, a delta of 0.3 percent. The Intel Xeon 6781P averages 315524, a 2 percent gap. The AMD EPYC 9575F averages 311774, a 3.2 percent difference. The AMD EPYC 9734 averages 310619, a 3.6 percent gap. These deltas show that the Threadripper 9980X leads this group by a narrow but consistent margin.

Where Each One Wins

Without head-to-head benchmark data, the comparison relies on architectural and specification differences recorded in the database. The Ryzen AI Embedded P174i targets the mobile segment with a 28 watt TDP, while the Threadripper 9980X targets desktop with a 350 watt TDP. That difference defines their respective operating envelopes.

The Threadripper 9980X wins decisively in parallel workloads. Its 64 cores and 128 threads versus 10 cores and 20 threads for the P174i mean any multi-threaded application that scales with core count will favor the Threadripper. The recorded Cinebench R20 multicore score of 54822 and R15 multicore score of 13157 for the Threadripper demonstrate this capability. The P174i has no comparable recorded scores to challenge that position.

The Ryzen AI Embedded P174i holds advantages in specific areas. Its integrated Radeon 880M graphics provide on-die display and compute capabilities, whereas the Threadripper 9980X has no integrated graphics. For embedded or mobile systems requiring a compact, low-power solution with graphics output, the P174i is the only option between the two. The Threadripper requires a discrete GPU for any visual output.

The P174i also offers a higher L1 cache per core at 80 KB versus 64 KB for the Threadripper. Both processors share 1 MB L2 per core and support ECC memory. The P174i supports DDR5 and LPDDR5X memory, while the Threadripper supports DDR5 only. Memory bandwidth differs substantially: 89.6 GB/s for the P174i versus 204.8 GB/s for the Threadripper, reflecting the quad-channel versus dual-channel memory buses.

The Threadripper 9980X has a higher base clock at 3.20 GHz versus 2.00 GHz, and a higher boost clock at 5.40 GHz versus 5.00 GHz. The Threadripper also has a much larger L3 cache at 256 MB versus 16 MB. For workloads that fit within the L3 cache, such as database operations or certain scientific simulations, the Threadripper's cache advantage is substantial.

Architecture Differences

The Ryzen AI Embedded P174i uses the Gorgon Point codename with a generation labeled "Ryzen AI Embedded (Zen 5 / Zen 5c)". The Threadripper 9980X uses the Shimada Peak codename with a generation labeled "Ryzen Threadripper (Zen 5 (Shimada Peak))". Both processors are built on a 4 nm process node at TSMC.

The P174i combines Zen 5 and Zen 5c cores in its design, a heterogeneous core arrangement suited to mobile power management. The Threadripper uses only Zen 5 architecture cores, uniform across all 64 cores. This architectural difference explains the P174i's lower TDP and smaller cache configuration.

The Threadripper 9980X uses a chiplet design with 8x 70.6 mm² dies, totaling 66,520 million transistors. The P174i uses a monolithic die at 233 mm². The chiplet approach allows the Threadripper to scale core count and cache capacity well beyond what a monolithic die could achieve within the same process node.

Cache architecture differs significantly. The P174i provides 80 KB L1 per core, while the Threadripper provides 64 KB L1 per core. The L3 totals diverge sharply: 16 MB for the P174i versus 256 MB for the Threadripper. The Threadripper's larger L3 cache can hold substantially more working data, reducing memory access latency for cache-resident workloads.

PCIe capabilities reflect their market positions. The P174i offers Gen 4 with 16 lanes, sufficient for embedded and mobile I/O needs. The Threadripper offers Gen 5 with 80 lanes, supporting high-bandwidth peripherals and multiple GPUs in workstation configurations. Both processors support ECC memory, indicating a shared focus on data integrity for professional workloads.

The generation labels in the database indicate that both belong to the Zen 5 family, with the P174i adding Zen 5c cores for efficiency. The Threadripper's homogeneous Zen 5 design maximizes performance consistency across all cores, while the P174i's heterogeneous design balances performance with power efficiency. These architectural choices directly explain the measured specification gaps in TDP, core count, cache size, and memory bandwidth.
