AMD Ryzen 5 Pro 9645 VS Intel Core i5-110

The most fundamental difference here is platform and purpose: the Ryzen 5 Pro 9645 is a desktop processor on the modern AM5 socket, while the Core i5-110 is a laptop chip on the older LGA 1200 socket — meaning these two are not direct competitors and serve entirely different use cases. Comparing them still reveals meaningful architectural gaps worth understanding.

The sharpest technical differentiator is manufacturing process: the Ryzen 5 Pro 9645 is built on a 4 nm node versus the Core i5-110′s 14 nm node. A smaller process node generally translates to better power efficiency and higher transistor density, meaning the AMD chip can do more work per watt. Both share the same 65W TDP, but that figure carries more headroom and efficiency on the 4 nm design. The Core i5-110 also permits a slightly higher 100 °C CPU temperature ceiling versus 95 °C for the Ryzen, which on a laptop is partly a consequence of tighter thermal envelopes rather than a true advantage.

On connectivity, the Ryzen 5 Pro 9645 supports PCIe 5.0 compared to the Core i5-110′s PCIe 3.0 — two full generations behind — which matters for NVMe SSD speeds and high-bandwidth discrete GPUs. Both chips include integrated graphics and full 64-bit support, so neither holds an edge there. Overall, the Ryzen 5 Pro 9645 has a clear architectural advantage in process technology and I/O modernity, though buyers must remember it targets a desktop build, while the Core i5-110 is constrained to laptop platforms.

Both processors field the same 6-core, 12-thread configuration, so raw parallelism is identical on paper. Where they diverge significantly is in clock speeds: the Ryzen 5 Pro 9645 runs a base of 3.9 GHz and boosts to 5.4 GHz, while the Core i5-110 starts at 2.9 GHz and peaks at 4.3 GHz. That 1 GHz gap at base and 1.1 GHz gap at turbo is substantial — in lightly threaded workloads like web browsing, office apps, or gaming, higher clock speeds translate directly into snappier responsiveness and faster single-core throughput.

Cache is the other major performance lever here. The Ryzen 5 Pro 9645 carries 32 MB of L3 cache — roughly 5.33 MB per core — compared to just 12 MB total (2 MB per core) on the Core i5-110. A larger cache means the processor can hold more frequently accessed data close to the cores, reducing costly trips to slower main memory. This pays dividends in cache-sensitive workloads: gaming, compilers, and data-heavy applications will all benefit noticeably from the AMD chip′s larger pool.

Neither chip offers an unlocked multiplier, so overclocking is off the table for both. Given the clock speed advantage, the considerably larger cache, and no compensating strength on the Intel side within this spec group, the Ryzen 5 Pro 9645 holds a clear and meaningful performance edge across virtually every workload category.

For integrated graphics, the only available data point is peak GPU turbo clock speed — and the gap is striking. The Ryzen 5 Pro 9645 reaches 2200 MHz at turbo, exactly double the Core i5-110′s 1100 MHz. GPU clock speed directly influences how quickly the integrated graphics unit can process rendering tasks, so a 2x frequency advantage points to meaningfully faster frame rates in light gaming, smoother video decode, and snappier GPU-accelerated workloads like image editing or display output.

It is worth noting that clock speed alone does not tell the full story of integrated GPU performance — shader count and memory bandwidth also matter — but those figures are not present in the provided data. Based strictly on what is available, the Ryzen 5 Pro 9645 holds a decisive advantage, and a doubling of turbo frequency is rarely a trivial gap regardless of other architectural variables.

Memory generation is where these two chips diverge most clearly. The Ryzen 5 Pro 9645 supports DDR5 at up to 5600 MHz, while the Core i5-110 is limited to DDR4 at 2666 MHz. That is more than double the peak memory bandwidth on the AMD side, which matters in workloads that are memory-bound — think large datasets, video editing timelines, or integrated graphics performance where the GPU shares system RAM. Faster memory also reduces latency bottlenecks that can throttle even a capable CPU.

Capacity headroom tells a similar story. The Ryzen 5 Pro 9645 supports up to 192 GB of RAM versus 128 GB on the Core i5-110 — a meaningful gap for users running virtual machines, large in-memory databases, or professional workstation workloads. Both processors use a dual-channel configuration, so neither has a structural advantage in channel architecture.

Perhaps the most telling differentiator for business and professional deployments is ECC support: the Ryzen 5 Pro 9645 supports ECC memory, while the Core i5-110 does not. ECC detects and corrects single-bit memory errors in real time, which is critical for data integrity in servers, workstations, and any environment where silent data corruption is unacceptable. Across every dimension of this group — speed, capacity, and reliability — the Ryzen 5 Pro 9645 holds an unambiguous advantage.

Across every data point in this group, the two chips are in complete lockstep. Both support an identical instruction set lineup — including AVX2, FMA3, AES, and SSE 4.1/4.2 — both use multithreading, and both include the NX bit security feature. There are no differentiators here to analyze.

The shared instruction sets do carry practical significance worth noting. AES acceleration means both chips handle encrypted storage and secure network traffic efficiently in hardware rather than software. AVX2 and FMA3 enable wider vectorized math operations, benefiting scientific computing, media encoding, and machine learning inference. These are well-established, broadly supported extensions that ensure software compatibility across the board for both processors.

Since every feature in this group is identical, this is a clear tie. Neither processor holds any advantage here, and this spec group should not factor into a purchasing decision between the two.
