AMD Ryzen AI Embedded P185 vs Intel Core Ultra 5 245T Comparison

Head-to-Head Benchmarks

The recorded data splits these two processors almost evenly, with Intel securing 6 wins and AMD taking 5 in the shared PassMark test suite. Despite that narrow win count, the magnitude of the victories tells a more complex story: AMD's wins are often decisive, while Intel's advantages range from narrow to overwhelming.

AMD's largest margin comes in integer math, where the Ryzen AI Embedded P185 scores 117832 against 88676 for the Core Ultra 5 245T, a 32.9% advantage. Data compression follows closely, with AMD at 374429 versus 283812, a 31.9% lead. Extended instructions also favor AMD by 20.3%, with scores of 26544 and 22071 respectively. The Ryzen part wins multithread by a modest 3.2%, posting 31817 against 30833, and random string sorting by 16.1%, with 40557 versus 34931.

Intel's wins are headlined by find prime numbers, where the Core Ultra 5 245T scores 324 against AMD's 129, a 60.2% lead. Floating point math also goes heavily to Intel, 108499 versus 70587, a 34.9% margin. Data encryption favors Intel by 17.1%, with 23656 against 19612. Physics testing gives Intel a 22.2% edge, 2278 versus 1772. Single-thread performance, measured by both passmark_single_thread and passmark_singlethread with identical scores, goes to Intel at 4367 versus 3977, an 8.9% difference.

The aggregate benchmark picture reflects a split personality. AMD's average benchmark score sits at 62839, placing it in the 93rd percentile of all CPUs. Intel's average score is 38194, which puts it in the 86th percentile. The delta between these averages is substantial, but the head-to-head tests show that Intel's strengths in specific workloads are real and sometimes dominant.

Architecture Differences

The foundational design choices diverge sharply. AMD uses a 12-core, 24-thread configuration built on the Gorgon Point codename, belonging to the Ryzen AI Embedded generation with Zen 5 and Zen 5c cores. Intel counters with a 14-core, 14-thread layout on the Arrow Lake-S codename, part of the Core Ultra Series 2 generation with Arrow Lake architecture. The thread count difference is notable: AMD offers simultaneous multithreading, Intel does not.

Process technology favors Intel on paper. Intel uses a 3 nm node from TSMC, while AMD uses a 4 nm node from the same foundry. Die sizes are close, with Intel at 243 mm² and AMD at 233 mm². Intel lists 17,800 million transistors; AMD does not report a transistor count in the database.

Cache hierarchies differ in structure and size. AMD provides 80 KB of L1 per core, 1 MB of L2 per core, and 16 MB of L3 cache. Intel provides 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3. The larger per-core caches on Intel partly explain its single-thread advantage, while AMD's 24 threads give it a multithread edge despite fewer cores.

Memory support shows both overlap and divergence. Both support DDR5 and dual-channel memory buses. AMD adds LPDDR5X support, which Intel lacks. Memory bandwidth favors Intel at 102.4 GB/s versus 89.6 GB/s. Both support ECC memory.

PCIe capabilities differ by generation. Intel offers Gen 5 with 20 lanes from the CPU, while AMD offers Gen 4 with 16 lanes. Integrated graphics also differ: AMD uses a Radeon 890M, Intel uses an Arc Xe-LPG Graphics 64EU. Sockets are incompatible, with AMD on Socket FP8 and Intel on Socket 1851.

Clock speeds are identical at the top end, both boosting to 5.10 GHz. Base clocks differ, with Intel at 2.20 GHz and AMD at 2.00 GHz. Thermal design power is not comparable in a direct sense: AMD is rated at 28 W, Intel at 65 W, reflecting AMD's mobile-oriented design versus Intel's desktop positioning. Release dates also separate them, with Intel launching on January 6, 2025, and AMD following on February 28, 2026. Intel carries a launch MSRP of $270; AMD has no listed launch MSRP.

FAQ

Q: Which processor has the higher multithread score?

A: AMD leads in passmark_multithread with 31817 against Intel's 30833, a 3.2% margin despite Intel having 14 cores to AMD's 12.

A: Yes, both the AMD Ryzen AI Embedded P185 and the Intel Core Ultra 5 245T list ECC memory as supported.

Q: Which processor supports PCIe Gen 5?

A: Intel supports PCIe Gen 5 with 20 CPU lanes. AMD supports PCIe Gen 4 with 16 CPU lanes.

Q: How do their average benchmark scores compare?

A: AMD's average is 62839, which places it in the 93rd percentile. Intel's average is 38194, placing it in the 86th percentile.

The Verdict

The data supports a workload-dependent choice rather than a single overall winner. AMD's Ryzen AI Embedded P185 delivers superior integer math, data compression, extended instruction throughput, random string sorting, and overall multithread performance. Its average benchmark score of 62839 versus Intel's 38194, combined with a 93rd versus 86th percentile placement, makes it the stronger all-around compute part in the database's aggregated metrics.

Intel's Core Ultra 5 245T claims the single-thread crown with 4367 versus 3977, and dominates in find prime numbers, floating point math, physics, and data encryption. Its 14 physical cores and larger cache hierarchy support these wins. For workloads that stress float point calculations, prime number generation, or encryption, the data points clearly to Intel.

The thermal and platform profiles reinforce the split. AMD's 28 W rating and mobile segment classification suggest deployment in power-constrained embedded systems. Intel's 65 W rating and desktop segment classification point toward conventional desktop builds. The socket choices, AMD FP8 versus Intel 1851, make platform selection a deciding factor before any benchmark is considered.

Where Each One Wins

AMD's Ryzen AI Embedded P185 wins in integer math, data compression, extended instructions, random string sorting, and the multithread benchmark. These results make it the pick for data-heavy workloads, compression pipelines, integer-dominated processing, and any scenario where 24 threads can be utilized. Its average benchmark score of 62839 and 93rd percentile ranking indicate broad competence across the full PassMark suite.

Intel's Core Ultra 5 245T wins in single-thread performance, find prime numbers, floating point math, physics, and data encryption. The 60.2% lead in find prime numbers and 34.9% lead in floating point math are the largest margins in either direction. These results favor scientific computing, encryption-heavy tasks, physics simulations, and lightly threaded applications where single-core speed matters. Its 4367 single-thread score is the highest recorded in the shared tests. The 86th percentile placement and average score of 38194 reflect a processor that excels in specific domains rather than across the board.
