AMD Ryzen 7 8745H VS Intel Core 5 120F

The most fundamental difference between these two processors is their intended platform: the AMD Ryzen 7 8745H is designed for both laptops and desktops, while the Intel Core 5 120F is a desktop-only chip. This makes the Ryzen 7 8745H a more versatile product by design, capable of powering thin-and-light notebooks as well as compact desktop systems.

From a power and manufacturing standpoint, the differences are significant. The Ryzen 7 8745H operates at a 45W TDP built on a modern 4 nm process node, whereas the Core 5 120F draws 65W on a comparatively older 10 nm node. The smaller process node of the Ryzen generally translates to better performance-per-watt — a critical advantage especially in thermally constrained environments like laptops. The Core 5 120F's higher TDP in a desktop-only context suggests it may rely more on raw power headroom rather than efficiency. On connectivity, the Core 5 120F supports the newer PCIe 5.0 versus the Ryzen's PCIe 4.0, which is a meaningful edge for users pairing the chip with next-generation NVMe SSDs or discrete GPUs that can exploit that bandwidth.

One standout exclusive to the Ryzen 7 8745H is integrated graphics, which the Core 5 120F entirely lacks — meaning the Intel chip requires a dedicated GPU to function at all, adding cost and power draw for desktop builders. Both processors share identical 100 °C maximum junction temperatures and full 64-bit support, so those are non-differentiators. Overall, the Ryzen 7 8745H holds a clear general-use advantage thanks to its efficiency, platform flexibility, and integrated graphics; the Core 5 120F's only notable edge is its PCIe 5.0 support, relevant mainly to users with cutting-edge storage or GPU hardware.

Looking at raw compute throughput, the Ryzen 7 8745H holds a commanding lead. Its 8 cores and 16 threads at a 3.8 GHz base clock outpace the Core 5 120F's 6 cores and 12 threads running at just 2.5 GHz base. That 1.3 GHz gap in base frequency is substantial — in sustained workloads like video encoding, compilation, or heavy multitasking where turbo boosts cannot be maintained indefinitely, the Ryzen's higher floor translates directly into faster sustained throughput. The turbo advantage reinforces this: the Ryzen peaks at 4.9 GHz versus the Core 5 120F's 4.5 GHz, meaning it also wins in short-burst, single-threaded scenarios.

The cache picture is more nuanced. The Core 5 120F carries a larger 18 MB L3 total versus the Ryzen's 16 MB, and a higher per-core L3 ratio of 3 MB/core compared to 2 MB/core. A bigger per-core L3 can reduce cache misses in latency-sensitive workloads like gaming or database queries, giving the Core 5 120F a narrow but real edge in those specific use cases. However, this advantage is contextual — it only matters when the workload fits within the cache and core count is not the bottleneck.

Neither chip offers an unlocked multiplier or big.LITTLE hybrid architecture, so overclocking and efficiency-core delegation are off the table for both. On balance, the Ryzen 7 8745H wins this group decisively: its superior core count, significantly higher base clock, and faster turbo ceiling make it the stronger performer across the widest range of workloads, with the Core 5 120F's per-core cache advantage being too narrow and scenario-specific to shift the overall verdict.

Both processors use DDR5 memory over a dual-channel configuration, so the generational foundation is identical. The critical divergence is in supported RAM speed: the Ryzen 7 8745H reaches up to 7500 MHz, while the Core 5 120F tops out at 4800 MHz. That is not a marginal gap — faster memory directly feeds the CPU with data more quickly, reducing stalls in bandwidth-sensitive tasks like video editing, large dataset processing, and notably, integrated graphics workloads where the GPU and CPU share the same memory pool. For the Ryzen in particular, where integrated graphics are present, the higher memory ceiling carries even more practical weight.

The maximum memory capacity tells a similar story. The Ryzen 7 8745H supports up to 256 GB of RAM versus 192 GB for the Core 5 120F. For most everyday users this distinction is academic, but for workstation-class tasks — virtual machines, large in-memory databases, professional content creation — that extra headroom can be the difference between a system that scales with demand and one that hits a ceiling prematurely. Neither chip supports ECC memory, so error-correcting capability is off the table for both, making them unsuitable for mission-critical server deployments regardless of capacity.

The Ryzen 7 8745H takes a clear win in this group. Its substantially higher memory speed ceiling and greater maximum capacity give it a meaningful advantage in both bandwidth-sensitive and memory-heavy workloads, while the Core 5 120F offers no compensating advantage within these specs.

This is a rare case where the two processors are in complete lockstep. Both the Ryzen 7 8745H and the Core 5 120F share an identical instruction set portfolio — including AVX2, AES, FMA3, and SSE 4.2, among others — and both support multithreading and carry the NX bit security feature. From a software compatibility and feature-set standpoint, no daylight exists between them.

The practical implication is that any application optimized for these instruction sets — whether it is a media encoder leveraging AVX2 for parallel data processing, encryption software using hardware-accelerated AES, or an OS relying on the NX bit to enforce memory protection against certain exploits — will run identically on either chip from a feature-support perspective. Developers and power users who specifically target these extensions will find no reason to favor one over the other based on this group alone.

This group is a complete tie. Neither processor holds any advantage here; the decision between them must rest entirely on the differentiators found in other specification groups such as performance, memory, or general platform characteristics.
