AMD Ryzen AI Embedded P164 vs Intel Core Ultra 9 285T Comparison

The Verdict

The recorded data presents a decisive outcome. The Intel Core Ultra 9 285T wins 11 of the 11 head-to-head benchmark comparisons against the AMD Ryzen AI Embedded P164. The Intel part holds a commanding lead in every measured workload, with the smallest margin being 12% in both extended instructions and single-thread performance. The data does not reveal a single category where the AMD processor takes the lead. The Intel Core Ultra 9 285T is the clear choice for any workload that can utilize raw compute throughput, while the AMD Ryzen AI Embedded P164 remains relevant only in contexts where its specific mobile platform characteristics, such as the 28 TDP and integrated Radeon 880M graphics, are prioritized over raw performance scores. Given the consistent deltas, the verdict from the database is unambiguous: the Intel processor outperforms the AMD processor across all recorded PassMark tests.

Architecture Differences

The two processors come from fundamentally different design philosophies and market segments. The AMD Ryzen AI Embedded P164 is a mobile-focused processor built on the Gorgon Point codename, using a hybrid Zen 5 and Zen 5c architecture on a 4 nm TSMC process. It features 8 cores and 16 threads, with a base clock of 2.00 GHz and a boost clock of 5.00 GHz. The chip integrates 8 MB of L3 cache, with 80 KB of L1 and 1 MB of L2 per core. Its memory controller supports DDR5 and LPDDR5X over a dual-channel bus, yielding 89.6 GB/s of bandwidth. The integrated graphics are Radeon 880M, and the CPU connects via PCIe Gen 4 with 16 lanes. The die size is 233 mm².

The Intel Core Ultra 9 285T is a desktop part from the Core Ultra Series 2, based on the Arrow Lake-S architecture on a 3 nm TSMC process. It packs 24 cores and 24 threads, indicating no hyper-threading, with a base clock of 1.40 GHz and a boost clock of 5.40 GHz. The cache hierarchy is substantially larger: 192 KB of L1 per core, 3 MB of L2 per core, and a shared 36 MB of L3. Memory support is limited to DDR5 over dual-channel, but the bandwidth is higher at 102.4 GB/s. The integrated graphics are Arc Xe-LPG Graphics with 64 EU, and the CPU uses PCIe Gen 5 with 20 lanes. The transistor count is listed at 17,800 million, and the die size is 243 mm². Both processors support ECC memory, and neither has an unlocked multiplier.

The process node difference is notable: 3 nm versus 4 nm, both from TSMC. However, the Intel part uses more transistors and a slightly larger die. The core count difference is stark: 24 cores versus 8 cores, which explains the multi-threaded performance gap. The Intel part also has a higher boost clock, though a lower base clock.

Where Each One Wins

Based strictly on the benchmark data, the Intel Core Ultra 9 285T wins every recorded category. There is no workload in the head-to-head table where the AMD Ryzen AI Embedded P164 emerges victorious. The most lopsided Intel advantage appears in find prime numbers, where the Intel score of 345 versus AMD's 71 represents a 79.4% delta. Floating point math also favors Intel heavily, with a 59.5% delta (137,923 versus 55,799). Data encryption shows a 49.9% delta (32,061 versus 16,055), and physics testing shows a 57.4% delta (2,842 versus 1,210). Even in the closest match, single-thread performance, Intel leads by 12% (4,576 versus 4,029).

The practical implication is that the Intel part is suited for compute-heavy desktop workloads: integer math, floating point, encryption, and multi-threaded rendering. The AMD part, while losing all benchmarks, has a lower TDP of 28 watts versus Intel's 35 watts, making it more appropriate for power-constrained mobile environments. The AMD processor also has a smaller L3 cache (8 MB versus 36 MB) and lower memory bandwidth (89.6 GB/s versus 102.4 GB/s), which correlates with its lower scores. The database does not provide any benchmark where the AMD processor's integrated Radeon 880M graphics outperform Intel's Arc Xe-LPG, as no graphics tests are recorded in the head-to-head set.

Head-to-Head Benchmarks

The head-to-head data is one-sided. The Intel Core Ultra 9 285T wins all 11 comparisons, with deltas ranging from 12% to 79.4%. The smallest margin is in single-thread performance and extended instructions, both at 12%. In the PassMark single-thread test, the Intel score is 4,576 versus AMD's 4,029. For extended instructions, Intel scores 27,477 versus AMD's 24,193. These are the closest contests, but Intel still leads.

The mid-range deltas include data compression at 14.6% (384,140 versus 327,891), random string sorting at 27% (47,695 versus 34,801), and integer math at 33.6% (132,433 versus 87,940). The multithread score shows Intel ahead by 35.2% (39,931 versus 25,889). The larger deltas appear in physics (57.4%, 2,842 versus 1,210), floating point math (59.5%, 137,923 versus 55,799), and data encryption (49.9%, 32,061 versus 16,055). The most extreme result is find prime numbers, where Intel's 345 is nearly five times AMD's 71, a 79.4% delta.

The average benchmark score in the database reinforces this trend. The AMD Ryzen AI Embedded P164 has an average score of 52,901, while the Intel Core Ultra 9 285T has an average of 51,310. Interestingly, the AMD part has a higher average score despite losing every head-to-head test. This is because the average includes different benchmark sets from the rival comparisons. The AMD part's nearest rivals include the AMD Ryzen 5 9500F (average 52,873, delta 0.1%), Intel Xeon 634 (average 52,974, delta -0.1%), AMD EPYC 7313P (average 53,206, delta -0.6%), and AMD Ryzen 9 7900X (average 53,288, delta -0.7%). The Intel part's nearest rivals are Intel Core i9-14900T (average 51,015, delta 0.6%), Intel Core i9-13900F (average 51,730, delta -0.8%), Intel Core i7-13850HX (average 50,761, delta 1.1%), and AMD Ryzen 9 5900XT (average 50,718, delta 1.2%). Both processors sit at the 91st percentile versus all CPUs, meaning they are in the same performance tier overall, but the head-to-head tests show Intel's dominance in the specific workloads measured.
