AMD Ryzen 3 PRO 8300G vs Intel Core i5-12450H Comparison

The AMD Ryzen 3 PRO 8300G and Intel Core i5-12450H are separated by a razor-thin 0.2% in average benchmark score, with the AMD part posting 17278 against Intel’s 17239. Despite this near-identical overall performance, the head-to-head results reveal two very different performance profiles: the Intel chip wins 12 of 17 direct comparisons, while the AMD chip takes 5, yet the AMD victories include some of the most dramatic margins in the entire dataset. The data shows a classic split between heavily threaded workloads and mixed single-thread/light-thread tasks.

Head-to-Head Benchmarks

The single largest delta in the comparison belongs to the Intel Core i5-12450H in PassMark floating-point math, where it scores 40568 against the AMD’s 23374 — a 42.4% advantage. This is not an isolated case of Intel dominance in math-heavy work; PassMark integer math also favors Intel by 31.9% (54782 vs 37292), and PassMark multithread shows Intel ahead by 17.8% (16265 vs 13368). The Intel part also leads in data compression by 22.8% (195132 vs 150567), data encryption by 20.5% (10832 vs 8607), and physics by 12.6% (883 vs 772). These are substantial margins that point to Intel’s advantage in sustained parallel throughput.

However, the AMD Ryzen 3 PRO 8300G delivers the most striking single result in Cinebench R23 multi-core, where it scores 12359 against Intel’s 8822.5 — a 40.1% lead. This is the only multi-core test in the set where AMD wins, and it does so by an enormous margin, suggesting that the AMD architecture handles this specific workload far more efficiently. In Cinebench R23 single-core, AMD also leads, but by a much narrower 5% (1744 vs 1661). PassMark single-thread shows AMD ahead by 7.4% (3550 vs 3306), and PassMark find prime numbers is essentially a tie, with AMD ahead by 2.2% (47 vs 46).

The older Cinebench versions tell a different story. In Cinebench R15 multi-core, Intel wins by 7.8% (1350 vs 1245), and in R20 multi-core Intel wins by 8.5% (5671 vs 5190). Single-core results in R15 and R20 also favor Intel by 26.5% (238 vs 175) and 8.5% (800 vs 732) respectively. This creates a contradictory picture: Intel dominates the older Cinebench versions, while AMD dominates the newer R23 version by a massive margin. The PassMark extended instructions test is close, with Intel ahead by only 4.5% (11992 vs 11451), and random string sorting also favors Intel by a modest 5.4% (20838 vs 19703).

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 3 PRO 8300G is built on the Zen 4 architecture, codenamed Phoenix2, using a 4 nm process from TSMC. It packs 4 cores and 8 threads, with a base clock of 3.40 GHz and a boost clock of 4.90 GHz. The Intel Core i5-12450H uses the Alder Lake architecture (Alder Lake-H) on Intel’s 10 nm process, with 8 cores and 12 threads — a hybrid configuration that is not explicitly detailed in the data but accounts for its higher core and thread counts. Intel’s base clock is listed as 2000.00 MHz, with a boost of 4.40 GHz.

Cache configurations differ notably. AMD provides 64 KB of L1 per core, 1 MB of L2 per core, and 8 MB of shared L3. Intel provides larger per-core caches: 80 KB of L1 per core, 1.25 MB of L2 per core, and 12 MB of shared L3. The Intel die is larger at 217 mm² compared to AMD’s 137 mm², though the data does not list a transistor count for Intel; AMD lists 20,900 million transistors. Both are built by their respective manufacturers, with AMD at TSMC and Intel in-house.

Memory support also diverges. AMD supports only DDR5 with dual-channel memory and lists a memory bandwidth of 83.2 GB/s, plus ECC memory support. Intel supports both DDR4 and DDR5 in dual-channel configuration, but no memory bandwidth figure is provided, and it lacks ECC support. The AMD part has 14 PCIe Gen 4 lanes, while Intel has 20 PCIe Gen 4 lanes. Integrated graphics differ as well: AMD uses the Radeon 740M, Intel uses UHD Graphics. The AMD is a desktop part on Socket AM5, while the Intel is a mobile part on BGA 1744, with a 65 W TDP for AMD versus 45 W for Intel.

The Verdict

The data presents a clear choice based on workload type. For users running Cinebench R23 multi-core, the AMD Ryzen 3 PRO 8300G is the definitive winner with a 40.1% lead. This is the most significant margin in the entire comparison, and it suggests that the AMD part excels in modern rendering workloads that scale with its Zen 4 architecture. The AMD also wins in single-thread PassMark tests by 7.4%, indicating a slight edge in lightly threaded applications.

For nearly everything else, the Intel Core i5-12450H is the stronger performer. Its 42.4% lead in floating-point math and 31.9% lead in integer math make it the better choice for numerical computation. The 22.8% advantage in data compression and 20.5% in encryption point to productivity tasks where Intel’s higher core count (8 vs 4) and thread count (12 vs 8) provide a tangible benefit. The 17.8% lead in PassMark multithread reinforces this, as does the 12.6% win in physics.

The overall average benchmark scores are nearly identical, but the distribution of wins matters. Intel wins 12 of 17 head-to-head tests, and its victories are spread across many common workloads. AMD wins only 5, but its Cinebench R23 multi-core victory is so large that it nearly balances the overall averages. The percentile rankings are the same for both (71st percentile), confirming that neither chip is categorically superior. The choice comes down to whether the user prioritizes the specific workload where AMD dominates or the broader set where Intel leads.
