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

Head-to-Head Benchmarks

The head-to-head data shows a decisive overall win for the Intel Core Ultra 5 245, which takes 10 of the 11 recorded benchmark comparisons. The lone AMD victory is substantial, but the breadth of Intel's wins across most workload categories is the defining pattern in this matchup.

The AMD Ryzen AI Embedded P185 claims only one benchmark win: PassMark integer math, where it scores 117,832 against Intel's 91,187. That is a 29.2% advantage, and it is the largest margin of victory in either direction across the entire test suite. This result indicates that the AMD processor has a clear edge in pure integer arithmetic workloads, which often correlate with general productivity tasks and certain database or financial applications.

Every other benchmark goes to the Intel Core Ultra 5 245, often by wide margins. The biggest gap is in PassMark find prime numbers, where Intel scores 365 against AMD's 129, a 64.7% difference. This is a test heavily influenced by single-thread efficiency and branch prediction, and Intel's result here is dominant. Floating-point math also shows a major separation: Intel posts 120,548 versus AMD's 70,587, a 41.4% lead. The extended instructions test favors Intel by 20.3% (33,304 versus 26,544), and data encryption shows a 35.1% gap (30,236 versus 19,612).

In multithreaded performance, the Intel part delivers 38,706 in PassMark multithread versus 31,817 for AMD, a 17.8% advantage. Physics simulation also goes to Intel by 31% (2,569 versus 1,772). Random string sorting favors Intel by 17.5% (49,140 versus 40,557), and data compression shows a narrower but still clear Intel win at 6.6% (400,942 versus 374,429). Single-thread scores favor Intel by 9.5%, with 4,394 versus 3,977 on both PassMark single-thread and single-thread variants, which are recorded identically.

The average benchmark score tells a different story than the head-to-head wins. AMD's average is 62,839, while Intel's is 48,995. This discrepancy arises because AMD's benchmark list includes different tests than Intel's, and the averages are not directly comparable across the full test sets. The percentile ranks show AMD at the 93rd percentile of all CPUs, while Intel sits at the 90th percentile. Both are strong positions, but AMD's overall standing among all processors is slightly higher despite losing most direct comparisons.

Where Each One Wins

The Intel Core Ultra 5 245 wins in most computationally intensive scenarios. Its advantages in floating-point math, physics simulation, and data encryption make it the stronger choice for scientific computing, engineering simulations, and workloads that involve cryptographic operations. The 41.4% lead in floating-point math is particularly relevant for rendering, numerical analysis, and any application that heavily uses trigonometry or matrix operations. The 35.1% edge in encryption also matters for secure data processing and VPN or TLS throughput.

Intel also wins in single-threaded tasks by 9.5%, which affects responsiveness in lightly threaded applications such as web browsing, office documents, and legacy software that does not scale across many cores. The 64.7% lead in find prime numbers further confirms Intel's strength in latency-sensitive, branch-heavy code. The data compression win at 6.6% is modest, but it still gives Intel an edge in file archiving and storage-related workloads.

The AMD Ryzen AI Embedded P185 wins only in integer math, with a 29.2% margin. This is a meaningful result for integer-heavy tasks like hash computations, certain types of data processing, and integer sorting algorithms. However, the win is isolated, and AMD does not lead in any other measured category. For mixed workloads, the Intel part demonstrates broader capability across more benchmark types.

The multithread score difference of 17.8% in Intel's favor is notable given that AMD has 24 threads against Intel's 14. Despite having 10 more threads, AMD cannot overcome Intel's per-thread performance advantage in the multithread test. This suggests that for heavily threaded workloads, Intel's architecture extracts more usable throughput from fewer threads.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen AI Embedded P185 uses the Gorgon Point codename and belongs to the Ryzen AI Embedded generation built on Zen 5 and Zen 5c cores. It is fabricated on TSMC's 4 nm process with a die size of 233 mm². The Intel Core Ultra 5 245 uses the Arrow Lake architecture, specifically Arrow Lake-S, and belongs to the Core Ultra Series 2 generation. It is built on TSMC's 3 nm node with a die size of 243 mm² and contains 17,800 million transistors.

Core configurations differ sharply. AMD provides 12 cores and 24 threads, meaning all cores support simultaneous multithreading. Intel provides 14 cores and 14 threads, with no hyperthreading enabled. Despite having fewer threads, Intel still outperforms AMD in most benchmarks, indicating superior per-thread execution efficiency.

Clock speeds are similar at the top end: both boost to 5.10 GHz. The base clocks differ, with AMD at 2.00 GHz and Intel at 3.50 GHz. The lower base clock on AMD likely reflects its mobile-oriented design and lower power envelope. AMD's thermal design power is 28 watts, while Intel's is 65 watts. This is a substantial difference in power budget, and it explains part of Intel's performance advantage in sustained workloads.

Cache hierarchies also diverge. AMD uses 80 KB of L1 cache per core, 1 MB of L2 per core, and 16 MB of L3 cache total. Intel uses 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3 cache. The larger per-core caches on Intel contribute to its single-thread performance edge, while the larger total L3 gives it more shared memory for multithreaded workloads.

Memory support differs in scope. AMD supports both DDR5 and LPDDR5X, while Intel supports only DDR5. Both use dual-channel memory buses. Intel has a higher memory bandwidth at 102.4 GB/s, compared to AMD's 89.6 GB/s. Both support ECC memory, which is relevant for data integrity in professional environments.

PCIe connectivity is significantly different. AMD provides Gen 4 with 16 lanes (CPU only), while Intel provides Gen 5 with 20 lanes (CPU only). The newer Gen 5 standard and additional lanes give Intel more headroom for high-speed storage and expansion cards.

Integrated graphics also differ. AMD uses the Radeon 890M, while Intel uses Arc Xe-LPG Graphics with 64 execution units. Both are integrated solutions, but their capabilities are not directly benchmarked in the provided data.

The market segments are distinct: AMD positions the P185 as a mobile processor, while Intel targets the desktop with the Ultra 5 245. AMD's socket is FP8, and Intel uses Socket 1851. Neither processor has an unlocked multiplier. Intel's part number is SRVFE; AMD's is listed as unknown. AMD's release date is recorded as February 28, 2026, while Intel's is January 6, 2025. Intel has a launch MSRP of $270.

The Verdict

The Intel Core Ultra 5 245 is the stronger performer in direct comparisons, winning 10 of 11 benchmarks. Its advantages are largest in find prime numbers (64.7%), floating-point math (41.4%), data encryption (35.1%), physics (31%), and integer math is the only category where AMD leads, by 29.2%. Intel also wins multithread (17.8%), random string sorting (17.5%), extended instructions (20.3%), data compression (6.6%), and single-thread (9.5%).

For builders choosing between these two, the data supports Intel for virtually all measured workloads except integer-heavy tasks. The 65-watt TDP and 3.50 GHz base clock on Intel indicate a desktop processor built for sustained performance. The 28-watt TDP and 2.00 GHz base clock on AMD indicate a mobile-oriented design that prioritizes efficiency over peak throughput.

The AMD part does hold a higher percentile rank (93rd versus 90th) and a higher average benchmark score (62,839 versus 48,995), but those metrics reflect different test sets and overall CPU standings, not direct head-to-head performance. In the tests where both processors were measured identically, Intel wins almost every time.

The choice depends on context. For a desktop build where power draw is not the primary constraint and performance across a broad range of workloads matters, the Intel Core Ultra 5 245 delivers better measured results in nearly every category. For a mobile or low-power embedded application where the 28-watt envelope is critical, the AMD Ryzen AI Embedded P185 provides competitive performance with far lower power consumption, and it wins integer math. The data does not show a scenario where AMD is preferable on raw performance grounds, but the power and socket differences are decisive for platform selection.
