AMD Ryzen 7 8745HX vs Intel Core Ultra 5 336H Comparison

The AMD Ryzen 7 8745HX and the Intel Core Ultra 5 336H are both active mobile processors aimed at high-performance laptops, yet their architectural philosophies and resulting benchmark profiles diverge sharply. The AMD chip, built on Zen 4, relies on 8 full-size cores with simultaneous multithreading, while Intel's Panther Lake design uses a 16-core configuration without extra threads, a 3 nm process, and a notably lower 25 W TDP compared to AMD's 55 W. The recorded data shows that these two processors split the PassMark suite nearly evenly, with the AMD part winning 6 tests and the Intel part winning 5, making the choice between them dependent on specific workload characteristics rather than overall superiority.

Where Each One Wins

The AMD Ryzen 7 8745HX demonstrates its strengths in tasks that benefit from large data throughput and integer-heavy operations. Its most dominant win comes in integer math, where it scores 100328 against Intel's 62070, a margin of 61.6%. This indicates a substantial advantage in general-purpose computing, database operations, and any workload that relies on branching logic and arithmetic on whole numbers. Data compression also leans heavily toward AMD, with a score of 363759 versus 280340, a 29.8% advantage, suggesting faster file archiving and storage management. Random string sorting, a test of memory access patterns and sorting algorithms, also favors AMD by 29.3%, with scores of 44494 and 34402 respectively. The multithread score, which aggregates performance across all threads, shows AMD ahead at 31517 versus 28545, a 10.4% lead, confirming that its 16 threads provide a measurable edge in parallel throughput over Intel's 16 threads that lack hyperthreading. Additionally, AMD wins the extended instructions test by 12.6% and data encryption by 2.6%, showing competence in cryptography and SIMD-like workloads.

The Intel Core Ultra 5 336H, meanwhile, carves out its wins in areas where its architecture excels: floating-point math, physics simulation, prime number finding, and single-threaded responsiveness. The floating-point math score of 82415 for Intel dwarfs AMD's 61972, a 24.8% difference in Intel's favor, indicating superior handling of scientific calculations, 3D rendering, and any software that heavily uses decimal arithmetic. The physics test, which often correlates with gaming performance and collision detection, sees Intel at 2682 versus AMD's 1681, a 37.3% lead. Prime number finding, a test that stresses integer division and algorithm efficiency, goes to Intel by a wide margin: 299 versus 159, a 46.8% difference. The single-thread score also favors Intel, with 4013 against AMD's 3879, a 3.3% edge, suggesting faster response in lightly threaded applications like web browsing and office suites.

The Verdict

From the data, the Ryzen 7 8745HX is the processor to select for users whose primary workloads involve heavy integer computation, large-scale data compression, or parallel multi-threaded applications. Its 61.6% lead in integer math and 29.8% lead in data compression are decisive, and its 10.4% advantage in the multithread score confirms that it handles concurrent tasks more efficiently. The chip's 92nd percentile ranking against all CPUs, compared to Intel's 84th, also places it higher in overall performance hierarchy, and its nearest rivals include the AMD Ryzen 9 7945HX and Intel Core i9-14900F, both of which are high-end desktop-class parts.

The Intel Core Ultra 5 336H is the better option for scenarios that prioritize floating-point throughput, physics-based simulations, or single-threaded responsiveness. Its 24.8% lead in floating-point math and 37.3% lead in physics make it attractive for creative professionals working with 3D models or scientific software. The 3.3% single-thread advantage, while small, can translate to snappier UI interactions and faster startup times for individual applications. However, its lower 84th percentile ranking and its nearest rivals, which include the Intel Core i7-13700HX and AMD Ryzen 7 3700X, indicate that it sits in a more mainstream performance tier.

Head-to-Head Benchmarks

The largest margin in this matchup is in integer math, where the AMD Ryzen 7 8745HX scores 100328 against 62070 for the Intel Core Ultra 5 336H, a 61.6% delta. This is a massive gap that will show up in any benchmark or application that performs a lot of arithmetic on whole numbers, such as compilers, data mining, or financial modeling. The second-largest win for AMD is in data compression, with 363759 versus 280340, a 29.8% lead, and random string sorting shows a similar 29.3% advantage. These three results paint a picture of a processor that is exceptionally strong at moving and organizing data.

On the Intel side, the biggest win is in prime number finding, where it scores 299 against AMD's 159, a 46.8% delta. This test is often a proxy for algorithmic efficiency and single-core integer performance, and the wide margin suggests Intel's architecture handles this specific pattern much better. The physics test follows with a 37.3% lead (2682 versus 1681), and floating-point math shows a 24.8% advantage (82415 versus 61972). These wins indicate that Intel's design has a fundamentally different strength profile, one that favors high-precision arithmetic and simulation workloads. The single-thread test is close, with Intel at 4013 and AMD at 3879, a 3.3% delta, showing that in everyday lightly threaded tasks, the two are nearly equivalent.

It features 8 cores and 16 threads, with a base clock of 3.60 GHz and a boost clock of 5.10 GHz. Its cache hierarchy includes 64 KB of L1 per core, 1 MB of L2 per core, and a large 32 MB shared L3 cache. The chip is designed for the AMD Socket FL1 and has a 55 W TDP. It also features an unlocked multiplier, allowing for overclocking on supported platforms.

The Intel Core Ultra 5 336H uses the Panther Lake architecture, manufactured on a more advanced 3 nm process by Intel's own foundry. It has 16 cores but only 16 threads, meaning it does not use simultaneous multithreading. Its base clock is 1.90 GHz, with a boost clock of 4.60 GHz, and it operates at a significantly lower 25 W TDP. The cache structure is different: 192 KB of L1 per core, 2.5 MB of L2 per core, and a smaller 18 MB shared L3 cache. It uses the Intel BGA 2540 socket and has a locked multiplier, preventing overclocking.

Specification Differences

The core counts and threading models differ substantially: AMD provides 8 cores and 16 threads, while Intel provides 16 cores and 16 threads, meaning Intel relies on physical cores only. Clock speeds also diverge, with AMD offering a higher base clock of 3.60 GHz versus Intel's 1.90 GHz, and a higher boost clock of 5.10 GHz versus 4.60 GHz. The TDP is another major differentiator, with AMD at 55 W and Intel at 25 W, indicating a large difference in power consumption and thermal output. The process nodes differ as well, with AMD on 5 nm and Intel on 3 nm. Memory support shows Intel accepting both DDR5 and LPDDR5X, while AMD lists only DDR5, and Intel's memory bandwidth is rated higher at 115.2 GB/s versus AMD's 83.2 GB/s. PCIe lanes also vary, with AMD offering 28 Gen 5 lanes and Intel offering 12 Gen 5 lanes. The integrated graphics differ, with AMD using Radeon 610M and Intel using Intel Xe3 Graphics.
