AMD Ryzen AI 9 PRO 465 vs Intel Core Ultra 5 245K Comparison

Where Each One Wins

The benchmark data splits these two processors along a clear line. The AMD Ryzen AI 9 PRO 465 takes exactly one of the eleven recorded head-to-head tests, while the Intel Core Ultra 5 245K wins the remaining ten. That single AMD victory comes in integer math, where the Ryzen scores 107,173 against Intel's 98,524, an 8.8% advantage. This suggests the AMD part has a specific strength in workloads that rely on integer arithmetic, a category that includes many general-purpose computing tasks such as database operations, financial calculations, and certain compile workloads.

Every other measured category favors Intel, and the margins are often substantial. In floating-point math, Intel more than doubles the AMD score, 130,678 versus 66,824, a 48.9% gap. The prime number finding test shows the largest relative difference, with Intel at 414 and AMD at 126, a 69.6% deficit for the Ryzen. Data encryption also heavily favors Intel, 33,286 versus 19,308, a 42% difference. These three tests point to a pattern: the Intel processor delivers far higher raw computational throughput in mathematically intensive and security-related tasks.

The multithreaded results reinforce this picture. Intel's PassMark multithread score is 43,047, while AMD manages 31,485, a 26.9% advantage for Intel. The physics test shows a 43.3% Intel lead, 3,081 to 1,747. Even in single-thread performance, where the AMD part has a respectable 4,168 score, Intel pulls ahead to 4,714, an 11.6% margin. The data compression test adds another Intel win, 458,817 against 385,174, a 16.1% difference. Extended instructions and random string sorting also go to Intel, by 29.7% and 25.8% respectively.

The overall picture is one of Intel dominance across nearly every computational domain measured. The AMD Ryzen AI 9 PRO 465 is a mobile-class processor with a modest 28-watt TDP, and it cannot match the desktop-oriented Intel part in sustained throughput. The single integer math win shows the Zen 5 architecture has its own strengths, but it does not translate into broader success in this benchmark suite.

Architecture Differences

The two processors come from fundamentally different design philosophies and market positions. The AMD Ryzen AI 9 PRO 465 is a mobile processor built on the Zen 5 architecture, codenamed Gorgon Point, part of the Ryzen AI PRO 400 generation. It uses a 4nm process from TSMC and has a die size of 233 mm². The Intel Core Ultra 5 245K is a desktop part based on the Arrow Lake architecture, specifically Arrow Lake-S, and belongs to the Core Ultra Series 2. It uses a more advanced 3nm process, also from TSMC, with a larger die at 243 mm² and 17,800 million transistors.

Core counts differ significantly. The AMD chip has 10 cores and 20 threads, meaning each core supports two threads. The Intel chip has 14 cores and 14 threads, with no simultaneous multithreading. This is a notable design split: AMD relies on thread-level parallelism, while Intel uses more physical cores each running a single thread. The AMD base clock is 2.00 GHz with a boost of 5.00 GHz, while the Intel part starts at 4.20 GHz and boosts to 5.20 GHz. Intel's higher base clock reflects its desktop power envelope.

Cache hierarchies also diverge. AMD provides 80 KB of L1 cache per core, 1 MB of L2 per core, and a 16 MB L3 cache. Intel gives 192 KB of L1 per core, 3 MB of L2 per core, and a larger 24 MB shared L3. The Intel L2 cache is three times larger per core, and the L3 cache is 50% larger overall. This extra cache likely contributes to Intel's strong performance in data-heavy tests like compression and encryption.

Memory support differs as well. AMD supports both DDR5 and LPDDR5X, with a dual-channel memory bus and 89.6 GB/s of bandwidth. Intel supports only DDR5, also dual-channel, but with higher bandwidth at 102.4 GB/s. Intel also includes ECC memory support, while AMD does not. PCIe capabilities favor Intel decisively: Gen 5 with 20 CPU lanes versus AMD's Gen 4 with 16 lanes. The integrated graphics differ, with AMD using Radeon 890M and Intel using Arc Xe-LPG Graphics 64EU.

The sockets are incompatible, as expected: AMD uses Socket FP8, Intel uses Socket 1851. AMD's multiplier is locked, while Intel's is unlocked for overclocking. The Intel part has a launch MSRP of $319. The AMD processor is newer, with a release date in January 2026, while Intel arrived in October 2024. Both are listed as active production parts.

Head-to-Head Benchmarks

The data compression test sets the tone for the comparison. Intel reaches 458,817, AMD 385,174, a 16.1% Intel lead. This test measures how quickly a processor can compress and decompress data, and the larger Intel cache and higher memory bandwidth likely contribute.

Data encryption shows a larger gap. Intel scores 33,286, AMD 19,308, a 42% difference. Encryption algorithms are computationally intensive and often benefit from dedicated instruction support and raw throughput. Intel's 3nm process and higher clocks help here.

The extended instructions test, which measures the performance of specialized CPU instruction sets, gives Intel a 29.7% win, 37,617 versus 26,441. This is a broad indicator of how well a processor handles vector and SIMD workloads.

The prime number test is the most lopsided. Intel scores 414, AMD 126, a 69.6% margin. This test is highly sensitive to integer division and branch prediction, and Intel's architecture appears far superior in this specific workload.

Floating-point math shows Intel at 130,678, nearly double AMD's 66,824. The 48.9% gap aligns with Intel's larger L2 and L3 caches and higher memory bandwidth, which help feed the floating-point units.

Integer math is the sole AMD win. AMD scores 107,173, Intel 98,524, an 8.8% advantage. This is a notable counter-trend, as it shows the Zen 5 architecture can outperform Arrow Lake in certain integer-heavy tasks despite losing in most other categories.

The multithread score goes to Intel, 43,047 versus 31,485, a 26.9% lead. Despite having fewer threads (14 versus 20), Intel's higher core count and clock speeds deliver more parallel throughput.

Physics simulation favors Intel by 43.3%, 3,081 to 1,747. Random string sorting gives Intel a 25.8% win, 55,098 to 40,860. Single-thread performance, measured twice in the data, shows Intel at 4,714 versus AMD's 4,168, an 11.6% margin.

The Verdict

The recorded benchmark data paints a consistent picture. The Intel Core Ultra 5 245K is the stronger processor in nearly every measurable category. Ten wins out of eleven tests, including dominant margins in floating-point math, prime number finding, and encryption, make it the clear choice for compute-heavy desktop workloads. Its 14 cores, higher clocks, larger caches, and 3nm process combine to deliver superior throughput across the board.

The AMD Ryzen AI 9 PRO 465 has a different role. It is a mobile processor with a 28-watt TDP, designed for laptops and portable systems. Its 20 threads and 10 cores on the Zen 5 architecture provide a respectable single integer math win, and its 93rd percentile ranking among all CPUs shows it is no slouch. But against a 125-watt desktop part, the performance gap is expected and consistent with their different market segments.

For desktop users who prioritize raw performance in multithreaded, floating-point, and encryption workloads, the Intel part is the better fit. For mobile users who need a capable processor with power efficiency and integrated Radeon 890M graphics, the AMD chip serves a different purpose. The data does not suggest they are direct competitors; it shows two processors built for different environments, with Intel dominating the performance comparisons that matter for desktop computing. The Intel part also offers ECC memory support, PCIe Gen 5, and an unlocked multiplier, features that further position it as a desktop enthusiast chip. The AMD part, with its locked multiplier and mobile socket, is optimized for a different use case entirely.
