AMD Ryzen AI 9 365 vs Intel Core Ultra 5 245K Comparison

Head-to-Head Benchmarks

The benchmark record for this pair is decisively one-sided. Across the 15 head-to-head tests logged in the database, the Intel Core Ultra 5 245K claims 14 wins, while the AMD Ryzen AI 9 365 manages a single victory. The most lopsided result appears in the PassMark prime number search test, where Intel scores 414 against AMD's 117, a delta of -71.7% for the Ryzen part. That is not a close contest by any measure. Floating point math also shows a massive gap: Intel posts 130,678 versus 62,802, a 51.9% deficit for the AMD chip. The data encryption test follows a similar pattern, with Intel at 33,286 and AMD at 18,297, a 45% shortfall.

The Cinebench results reinforce the same hierarchy. In Cinebench R23 multi-core, Intel reaches 25,066 while AMD scores 18,698, a 25.4% difference. The single-core R23 test is closer but still favors Intel, 2,132 to 1,992, a 6.6% gap. Cinebench R15 multi-core shows Intel at 3,850 versus AMD's 2,842, a 26.2% margin, and the R15 single-core test lands at 322 versus 303, a 5.9% difference. The pattern holds across PassMark's multithread test, where Intel's 43,047 beats AMD's 29,467 by 31.5%. Physics simulation is also heavily Intel-favored: 3,081 versus 1,704, a 44.7% gap.

The one AMD win comes in PassMark integer math. Here the Ryzen AI 9 365 scores 101,831 against Intel's 98,524, a 3.4% advantage. It is a narrow margin, and it stands alone in an otherwise Intel-dominated dataset. The single-thread PassMark tests show Intel ahead by 18.5% in both recorded entries, with scores of 4,714 versus 3,841. Data compression favors Intel at 458,817 versus 354,510, a 22.7% lead. Extended instructions go Intel's way as well: 37,617 versus 25,113, a 33.2% margin. Random string sorting shows Intel at 55,098 versus 39,447, a 28.4% advantage.

Looking at the aggregate average benchmark score, Intel sits at 54,053, which places it in the 91st percentile of all CPUs. AMD's average is 40,048, landing in the 87th percentile. The nearest rival data for Intel shows it trading blows with the AMD Ryzen 9 9900X3D, which sits 1.3% higher, and the Intel Core i7-14700F at 0.8% lower. AMD's nearest rivals include the AMD Ryzen 7 7700 at 0.1% higher and the Intel Core 5 221E at 0.2% higher, indicating that the Ryzen AI 9 365 sits in a tightly contested performance band just below the top-tier desktop parts. The Intel part's nearest rival list includes server-class silicon like the Xeon 6505P and the Xeon Phi 7290, underscoring its position in higher-performing territory.

Architecture Differences

The two processors come from fundamentally different design philosophies. AMD's Ryzen AI 9 365 uses the Zen 5 architecture under the Strix Point codename, built on a 4 nm process at TSMC. It packs 10 cores and 20 threads, leveraging simultaneous multithreading. Intel's Core Ultra 5 245K uses the Arrow Lake architecture, specifically Arrow Lake-S, built on a 3 nm process, also at TSMC. It has 14 cores but only 14 threads, meaning it does not use hyper-threading on any of its cores. This explains why Intel can win heavily in multi-threaded workloads despite having fewer threads: its core count is higher, and each core operates at a higher clock speed.

The process node difference is modest, 4 nm versus 3 nm, but the transistor counts tell a different story. Intel's die contains 17,800 million transistors across a 233 mm² die. AMD's transistor count is not recorded in the database, but its die size is 233 mm² as well. The cache layouts diverge sharply. AMD provides 80 KB of L1 cache per core, 1 MB of L2 per core, and 16 MB of shared L3. Intel offers 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3. Intel's larger caches, especially the L3, likely contribute to its strong performance in data compression and encryption tests.

Memory support also differs. Both support DDR5, but AMD adds LPDDR5X, which suits its mobile positioning. Intel supports only DDR5. Memory bandwidth is higher on the Intel side: 102.4 GB/s versus 89.6 GB/s. Both use dual-channel memory buses. AMD does not support ECC memory, while Intel does. PCIe connectivity favors Intel, which offers Gen 5 with 20 lanes, compared to AMD's Gen 4 with 16 lanes. The integrated graphics differ as well: AMD uses the Radeon 880M, while Intel uses the Arc Xe-LPG Graphics 64EU.

The market segments are clearly split. AMD's chip is a mobile part, designed for Socket FP8, with a 28 W TDP. Intel's is a desktop part on Socket 1851, with a 125 W TDP. That power envelope difference is substantial and explains a portion of the performance gap. The Intel part also has an unlocked multiplier, while AMD's does not. The release dates are close, with AMD launching on 2024-06-30 and Intel on 2024-10-23. Intel's launch MSRP is $319, a figure the database records once.

FAQ

The Verdict

The data points to a clear performance hierarchy. The Intel Core Ultra 5 245K dominates the benchmark suite, winning 14 of 15 tests and posting advantages ranging from 5.9% to 71.7% depending on the workload. Its wins span multi-core rendering, single-core tasks, encryption, compression, floating point math, physics simulation, and single-threaded tests. The only category where it loses is integer math, and even there the margin is just 3.4%. The Intel part also benefits from a higher average benchmark score (54,053 versus 40,048) and a higher percentile ranking (91st versus 87th).

The AMD Ryzen AI 9 365 is a mobile chip with a 28 W TDP, and that power constraint is visible in the results. It does not compete on raw throughput in most workloads. Its 20 threads do not compensate for Intel's higher core count and clock speeds. The single win in integer math suggests a strength in specific arithmetic workloads, but it is an outlier rather than a trend. For anyone selecting a desktop CPU based on recorded performance, the Intel Core Ultra 5 245K is the stronger part by a wide margin. For a mobile part, the AMD chip's lower TDP and LPDDR5X support make it a different class of product, but the database shows no scenario where it outperforms the Intel desktop part outside of that narrow integer math result.
