Architecture Differences

The AMD Ryzen 5 PRO 8645HS is built on Zen 4 architecture with the Hawk Point codename, manufactured on a 4nm process at TSMC. It uses 25,000 million transistors on a 178 mm² die. The Intel Core 7 350 uses Wildcat Lake architecture, fabricated on Intel's 3nm process. The Intel chip has no transistor count or die size recorded in the database.

Cache layouts differ significantly. The AMD part allocates 64 KB of L1 cache per core, 1 MB of L2 per core, and 16 MB of shared L3 cache. The Intel Core 7 350 has 192 KB of L1 per core, 2.5 MB of L2 per core, but only 6 MB of shared L3. The larger L3 pool on the AMD chip gives it a meaningful advantage in workloads that repeatedly access a working set larger than 6 MB.

Memory support also separates these two. The AMD Ryzen 5 PRO 8645HS supports DDR5 only, with a dual-channel interface. The Intel Core 7 350 supports both DDR5 and LPDDR5X, but uses a single-channel memory bus. The AMD chip's dual-channel setup results in 89.6 GB/s of bandwidth versus 59.7 GB/s for Intel. The Intel part also lacks ECC support entirely.

PCIe connectivity differs as well. The AMD processor provides Gen 4 with 20 lanes from the CPU. The Intel Core 7 350 provides Gen 4 with only 6 lanes. For systems that need multiple NVMe drives or discrete GPUs, the AMD platform offers more headroom.

Integrated graphics are present in both. The AMD processor uses a Radeon 760M, while the Intel chip uses Intel Xe3 Graphics with 2 Xe cores. The database does not include graphics benchmarks for either part.

The AMD chip uses AMD Socket FP7, and the Intel chip uses Intel BGA 1516. Neither processor has an unlocked multiplier. The AMD part was released on 2024-04-15, while the Intel part has a release date of 2026-04-15 in the recorded data. The Intel Core 7 350 has a launch MSRP of $469; the AMD part has no recorded launch MSRP.

The Verdict

The AMD Ryzen 5 PRO 8645HS wins 13 of the 17 head-to-head benchmark comparisons, including every Cinebench multi-core test and the vast majority of PassMark workloads. Its 12 threads give it a decisive edge in heavily parallel tasks. The Cinebench R23 multi-core result of 19,742 versus 8,030 is a 145.9% gap, the largest single margin in the dataset. For anyone running rendering, encoding, compression, or other multi-threaded workloads, the AMD part is the clear choice.

The Intel Core 7 350 wins 4 comparisons, all of which are single-thread or simple integer workloads. It takes Cinebench R15 single-core by 4.1%, PassMark single-thread by 5.9%, and PassMark find prime numbers by 31.8%. The Intel chip also has a 15W TDP versus 45W, so it fits platforms with tighter thermal and power budgets. The data suggests the Intel part is preferable for basic single-threaded tasks and low-power mobile designs, while the AMD processor dominates anything that can use multiple threads.

Head-to-Head Benchmarks

The AMD Ryzen 5 PRO 8645HS dominates multi-core tests across the board. In Cinebench R15 multi-core, it scores 1,989 versus 1,220, a 63% advantage. Cinebench R20 multi-core shows 8,291 against 5,373, a 54.3% lead. The R23 multi-core result is even more lopsided: 19,742 versus 8,030, a 145.9% margin. These results track directly with the thread count difference: 12 threads on the AMD side versus 6 on the Intel side.

Single-core results are more mixed. The Intel Core 7 350 wins Cinebench R15 single-core with 292 versus 280, a 4.1% margin. However, the AMD part wins Cinebench R20 single-core with 1,170 versus 758, a 54.4% lead. In Cinebench R23 single-core, AMD wins again with 2,787 versus 2,046, a 36.2% margin. The PassMark single-thread test favors Intel, showing 4,100 versus 3,858, a 5.9% advantage.

PassMark integer math heavily favors AMD: 72,740 versus 33,734, a 115.6% gap. Floating point math is closer, with AMD taking 45,481 versus 42,809, a 6.2% margin. Data compression shows AMD at 265,826 versus 143,123, an 85.7% lead. Data encryption goes to AMD by 59%, scoring 17,387 versus 10,933. Extended instructions also favor AMD, 21,212 versus 12,045, a 76.1% difference.

Random string sorting is another AMD win, 35,472 versus 17,238, a 105.8% margin. The multithread PassMark test shows 23,569 versus 15,170, a 55.4% lead for AMD. Physics is nearly even: AMD scores 1,208 and Intel scores 1,173, a 3% difference.

The one workload where Intel wins decisively is PassMark find prime numbers. Intel scores 107 versus AMD's 73, a 31.8% advantage. This is a narrow, integer-heavy workload that does not scale with thread count, and the Intel core's higher per-thread efficiency shows here.

Where Each One Wins

The AMD Ryzen 5 PRO 8645HS wins in every multi-threaded scenario represented in the benchmark data. Rendering workloads like Cinebench R15, R20, and R23 multi-core all show large AMD leads, ranging from 54.3% to 145.9%. Content creation, video encoding, 3D rendering, and software compilation are the obvious use cases. The 16 MB of shared L3 cache and dual-channel memory also support data-heavy tasks like compression and encryption, where AMD leads by 85.7% and 59% respectively.

The AMD part also wins integer math by 115.6%, random string sorting by 105.8%, and extended instructions by 76.1%. These results indicate strong performance in spreadsheet calculations, database operations, sorting algorithms, and any code that uses SIMD or advanced instruction sets. The 12 threads and 45W TDP give it the headroom to sustain these workloads.

The Intel Core 7 350 wins in single-threaded workloads that do not use multiple cores. PassMark single-thread shows a 5.9% lead, and Cinebench R15 single-core shows a 4.1% lead. The find prime numbers test, which is a tight loop of integer operations, shows Intel ahead by 31.8%. These wins suggest the Intel core has higher per-thread efficiency despite the lower boost clock of 4.80 GHz versus 5.00 GHz.

The Intel part also has a 15W TDP, which makes it suitable for fanless or ultra-portable designs where power draw and heat are the primary constraints. Its support for LPDDR5X memory adds flexibility for thin-and-light laptops. The single-channel memory bus limits bandwidth-heavy tasks, but the lower power envelope is an advantage in battery-operated systems.

In summary, the AMD Ryzen 5 PRO 8645HS is the stronger processor for multi-core and memory-intensive workloads, while the Intel Core 7 350 holds an edge in selected single-threaded tasks and offers a much lower power draw.
