AMD Ryzen 3 PRO 8300G vs Intel Core Ultra 9 285 Comparison

The AMD Ryzen 3 PRO 8300G and Intel Core Ultra 9 285 occupy completely different tiers of the desktop processor market. The benchmark data shows a decisive sweep for the Intel part across every single recorded test. The Intel Core Ultra 9 285 wins all 17 head-to-head comparisons, with the smallest margin being a 27.3% advantage in single-threaded PassMark tests. The AMD Ryzen 3 PRO 8300G, while a modern and efficient 4-core part, cannot match the raw throughput of the 24-core Intel flagship in any workload category.

Where Each One Wins

The data is unambiguous: the Intel Core Ultra 9 285 wins every benchmark category. There are no workload segments where the AMD Ryzen 3 PRO 8300G posts a higher score. This is a complete sweep across Cinebench rendering tests and the full PassMark suite, including integer math, floating-point math, encryption, compression, physics, and prime number finding.

The Intel part's largest advantage appears in prime number finding, where it leads by 89.8%. The AMD processor scores 47 in PassMark find prime numbers, while the Intel delivers 459. This indicates a massive disparity in raw integer calculation throughput. The floating-point math test shows the second-largest gap at 88%, with Intel scoring 194988 against AMD's 23374. Data encryption also shows a significant 81.7% lead for Intel, scoring 46949 versus 8607.

The narrowest margin occurs in the PassMark single-thread tests, where the Intel Core Ultra 9 285 leads by 27.3% with a score of 4881 against the AMD's 3550. This remains a substantial gap, but it is the only test where the Intel advantage falls below 70 percentage points. The single-core Cinebench tests still show a 74.8% to 74.9% lead for Intel, indicating that the performance difference is not solely a function of core count.

Architecture Differences

The two processors use fundamentally different silicon designs. The AMD Ryzen 3 PRO 8300G uses the Zen 4 architecture with the Phoenix2 codename, built on a 4 nm process at TSMC. The Intel Core Ultra 9 285 uses the Arrow Lake architecture with the Arrow Lake-S codename, fabricated on a 3 nm process, also at TSMC. The Intel part is physically larger at 243 mm², while the AMD die measures 137 mm². Interestingly, the AMD chip contains more transistors at 20,900 million compared to Intel's 17,800 million.

Core configuration differs drastically. The AMD Ryzen 3 PRO 8300G is a 4-core, 8-thread processor, while the Intel Core Ultra 9 285 is a 24-core, 24-thread processor. The Intel part does not use simultaneous multithreading, hence threads equal cores. The AMD part uses standard SMT, giving it 8 threads from 4 cores. Clock speeds also favor Intel: the AMD boosts to 4.90 GHz from a 3.40 GHz base, while the Intel boosts to 5.60 GHz from a 2.50 GHz base.

Cache hierarchy shows Intel's advantage in shared L3, offering 36 MB versus the AMD's 8 MB. The per-core L1 and L2 caches are also larger on Intel: 192 KB and 3 MB per core respectively, against 64 KB and 1 MB per core on the AMD. Both processors support DDR5 memory with dual-channel buses, but the Intel part has higher memory bandwidth at 102.4 GB/s compared to 83.2 GB/s. Both support ECC memory. PCIe connectivity differs, with Intel offering Gen 5 with 20 lanes, while AMD provides Gen 4 with 14 lanes.

The integrated graphics also differ. The AMD uses the Radeon 740M, while the Intel uses the Arc Xe-LPG Graphics 64EU. Both processors are locked, with no unlocked multiplier. The AMD uses the AM5 socket, and the Intel uses Socket 1851. Both are listed as desktop market segment parts with active production status.

The Verdict

The data directs a clear conclusion: the Intel Core Ultra 9 285 is the superior processor in every measured workload. Its 24-core configuration, larger cache, higher boost clock, and greater memory bandwidth produce benchmark results that the AMD Ryzen 3 PRO 8300G cannot approach. The Intel part sits in the 95th percentile of all CPUs, while the AMD part sits in the 71st percentile. The average benchmark score for the Intel is 75488, compared to 17278 for the AMD.

The AMD Ryzen 3 PRO 8300G is a 4-core desktop processor with Zen 4 architecture, and its recorded scores place it near the Intel Core i5-12450H, which has an average score of 17239, a 0.2% difference. The Intel Core Ultra 9 285, by contrast, is bracketed by server-class AMD EPYC processors, including the EPYC 4545P with an average score of 75373, a 0.2% difference. This places the two parts in entirely different performance classes.

Buyers should choose the Intel Core Ultra 9 285 when maximum multi-threaded throughput is the priority. The benchmark results show dominant wins in rendering, encryption, compression, and compute-heavy tasks. The AMD Ryzen 3 PRO 8300G remains a functional 4-core, 8-thread desktop option, but the recorded data offers no workload where it outperforms the Intel part. The performance gap is consistent and large across all 17 tests, with the smallest margin still exceeding 27%.
