Architecture Differences

The two processors come from fundamentally different design philosophies. The Intel Core i5-12450HX uses the Alder Lake architecture, built on Intel's 10 nm process. It is part of the Alder Lake-HX generation, a mobile variant designed for high-performance laptops. The die size is 215 mm². The AMD Ryzen 7 7735HS uses the Zen 3+ architecture, built on TSMC's 6 nm process. It belongs to the Rembrandt-R generation and has a die size of 210 mm².

Cache hierarchies differ significantly. Intel allocates 80 KB of L1 cache per core and 1.25 MB of L2 cache per core. AMD uses 64 KB of L1 per core and 512 KB of L2 per core. The L3 cache favors AMD, with 16 MB shared versus Intel's 12 MB shared. These differences help explain the multi-threaded performance gap, as AMD's larger shared cache and higher thread count give it an advantage in data-heavy workloads.

Memory support also diverges. Intel supports both DDR4 and DDR5, giving laptop makers flexibility. AMD supports DDR5 only, but the database records a memory bandwidth figure of 76.8 GB/s for the AMD chip. Intel's memory bandwidth is not listed. Both use dual-channel memory buses.

PCIe support differs by generation. Intel offers Gen 5 with 20 lanes (CPU only), while AMD offers Gen 4 with 20 lanes (CPU only). The integrated graphics are also different: Intel pairs the CPU with UHD Graphics 710, while AMD includes the Radeon 680M. AMD also supports ECC memory, while Intel does not.

The manufacturing foundries are distinct. Intel fabricates its chip in-house, while AMD uses TSMC. The process node advantage goes to AMD, with 6 nm versus Intel's 10 nm. This likely contributes to the AMD chip's lower TDP of 35 watts against Intel's 55 watts.

Specification Differences

The two processors differ across nearly every major specification field. The Intel Core i5-12450HX has 8 cores and 12 threads, while the AMD Ryzen 7 7735HS has 8 cores and 16 threads. Base clocks favor AMD at 3.20 GHz versus 2.40 GHz. Boost clocks also favor AMD at 4.75 GHz versus 4.40 GHz.

Thermal design power shows a significant gap. Intel is rated at 55 watts, while AMD is rated at 35 watts. The sockets are incompatible: Intel uses BGA 1964, and AMD uses Socket FP7. Process nodes differ, with Intel on 10 nm and AMD on 6 nm. The foundries are Intel and TSMC respectively.

Cache configurations are distinct. Intel uses 80 KB L1 per core and 1.25 MB L2 per core, while AMD uses 64 KB L1 per core and 512 KB L2 per core. L3 cache is 12 MB shared for Intel and 16 MB shared for AMD. Memory support shows Intel accepting both DDR4 and DDR5, while AMD accepts DDR5 only. AMD records a memory bandwidth of 76.8 GB/s, while Intel does not list one.

ECC memory support is exclusive to AMD. PCIe generations differ, with Intel at Gen 5 and AMD at Gen 4, though both offer 20 lanes. Integrated graphics are UHD Graphics 710 for Intel and Radeon 680M for AMD. The Intel chip has an unlocked multiplier, while the AMD chip does not. Release dates differ, with Intel launching on 2022-05-09 and AMD on 2023-03-31. Intel has a launch MSRP of $284, while AMD has no recorded launch MSRP.

Where Each One Wins

The AMD Ryzen 7 7735HS is the clear choice for multi-threaded and throughput-oriented tasks. Its 16 threads, larger L3 cache, and higher clock speeds give it commanding leads in integer math, encryption, compression, and extended instruction workloads. The 33% lead in integer math and the 33.6% lead in data encryption are the kind of margins that matter for content creation, compilation, and data processing. The Cinebench R23 multi-core result, a 13.1% advantage, reinforces this strength in rendering workloads.

The Intel Core i5-12450HX wins in specific single-thread scenarios. The 37.1% lead in Cinebench R23 single-core is the standout result, suggesting that Intel's architecture can deliver exceptional performance when a workload is limited to one thread. The narrow wins in PassMark single-thread (1.3%) and physics (1.2%) are smaller but consistent. For legacy applications, lightly threaded games, or tasks that rely on a single fast core, the Intel chip has a measurable edge.

The overall benchmark data favors AMD by a wide margin. With 11 wins out of 15 tests and a higher average benchmark score (25147 versus 24576), the Ryzen 7 7735HS is the more balanced performer. The Intel chip's single-thread wins are real, but they are concentrated in a narrow set of tests. The AMD chip wins across a broader range of workloads, including several where the margin exceeds 20%. For users who need consistent performance across diverse tasks, the data points clearly to the AMD Ryzen 7 7735HS.
