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

The AMD Ryzen 3 8300G and Intel Core Ultra 9 285 occupy opposite ends of the desktop performance spectrum. The recorded benchmark data shows a complete sweep in favor of the Intel part, with the Ryzen 3 failing to secure a single win across all 17 head-to-head tests. The average benchmark score for the AMD chip is 18,169, placing it in the 72nd percentile of all CPUs, while the Intel chip scores 75,488 on average, landing in the 95th percentile. This is not a close contest; the data indicates a fundamental difference in class and capability.

Where Each One Wins

The straightforward answer from the database is that the Intel Core Ultra 9 285 wins every recorded benchmark. The AMD Ryzen 3 8300G has zero wins in the head-to-head comparison, and the Intel part has 17. This makes the use-case split exceptionally one-sided. The Intel processor is designed for heavy multi-threaded workloads, content creation, and any task that scales with core count. Its dominance in PassMark multithread (56,602 vs 14,018) and Cinebench R23 multicore (48,945 vs 12,217) indicates it is the appropriate choice for rendering, compiling, and scientific computing.

The Ryzen 3 8300G wins in no measurable category. However, its lower power draw at 65W TDP and integrated Radeon 740M graphics suggest it is intended for basic desktop use where the CPU is not the primary focus. The data does not show any scenario where the Ryzen 3 outperforms the Ultra 9, so the practical split is between a processor that handles everything and one that handles light tasks efficiently. The closest the AMD chip comes to competitiveness is in PassMark single-thread, where it trails by 22.6% (3,778 vs 4,881), but even that is a decisive victory for Intel.

Architecture Differences

The two processors are built on completely different design philosophies and manufacturing processes. The AMD Ryzen 3 8300G uses the Zen 4 architecture on a 4nm TSMC node, with the Phoenix2 codename. It packs 4 cores and 8 threads, which means it relies on simultaneous multithreading to double its thread count. The Intel Core Ultra 9 285 uses the Arrow Lake architecture on a 3nm TSMC node, with the Arrow Lake-S codename. It has 24 cores and 24 threads, with no hyperthreading. The Intel chip uses a larger die at 243 mm² compared to the AMD's 137 mm², though the AMD chip has more transistors at 20,900 million versus Intel's 17,800 million.

Cache hierarchies differ substantially. The AMD chip provides 64 KB of L1 per core, 1 MB of L2 per core, and 8 MB of shared L3. The Intel chip offers 192 KB of L1 per core, 3 MB of L2 per core, and 36 MB of shared L3. This gives Intel a massive advantage in cached data capacity, which directly supports its higher core count. Process node differences also matter: the 3nm node on Intel is denser than the 4nm node on AMD, although the AMD die is smaller overall.

Both support DDR5 memory in dual-channel mode, but Intel has a higher memory bandwidth at 102.4 GB/s versus AMD's 83.2 GB/s. Both support ECC memory. PCIe generation differs, with AMD using Gen 4 with 14 lanes and Intel using Gen 5 with 20 lanes, giving Intel both more lanes and a faster standard. The integrated graphics also differ: AMD uses a Radeon 740M, while Intel uses Arc Xe-LPG Graphics with 64 execution units.

Head-to-Head Benchmarks

The Cinebench results show a consistent pattern of Intel dominance. In Cinebench R15 multicore, the Intel chip scores 4,933 versus AMD's 1,231, a 75% deficit for AMD. The single-core R15 test shows 696 vs 173, also a 75.1% gap. Cinebench R20 multicore shows 20,556 vs 5,131, a 75% difference, while single-core R20 shows 2,901 vs 724, another 75% gap. Cinebench R23 multicore delivers 48,945 vs 12,217, and single-core delivers 6,909 vs 1,724, both at 75% deficits.

PassMark tests reveal the largest gaps. Floating point math shows Intel at 194,988 vs AMD's 25,336, an 87% deficit. Find prime numbers shows 459 vs 47, a massive 89.8% gap, the largest in the entire benchmark suite. Data encryption shows 46,949 vs 9,115, an 80.6% deficit. Physics shows 3,598 vs 755, a 79% gap. These results indicate that the Intel chip is not just faster in raw throughput but also in specialized instruction handling and integer operations.

The smallest gap is in PassMark single-thread, where Intel scores 4,881 vs AMD's 3,778, a 22.6% deficit. This is still a clear win for Intel, but the narrower margin suggests that for lightly threaded workloads, the AMD chip is comparatively less disadvantaged. Data compression shows 602,121 vs 158,952, a 73.6% deficit. Extended instructions show 45,357 vs 12,354, a 72.8% gap. Integer math shows 164,869 vs 40,534, a 75.4% gap. Random string sorting shows 73,651 vs 19,013, a 74.2% gap. Multithread shows 56,602 vs 14,018, a 75.2% deficit.

Specification Differences

The specification sheet highlights the core count disparity as the primary differentiator. The AMD Ryzen 3 8300G has 4 cores and 8 threads, while the Intel Core Ultra 9 285 has 24 cores and 24 threads. Base clocks differ, with AMD at 3.40 GHz and Intel at 2.50 GHz, but the boost clocks reverse this, with AMD at 4.90 GHz and Intel at 5.60 GHz. Both have a 65W TDP, so power consumption is identical per the specifications.

Memory bandwidth favors Intel at 102.4 GB/s versus AMD's 83.2 GB/s. PCIe lanes favor Intel with 20 Gen 5 lanes versus AMD's 14 Gen 4 lanes. The process node is different, with AMD at 4nm and Intel at 3nm. Die size is 137 mm² for AMD and 243 mm² for Intel. Transistor counts are 20,900 million for AMD and 17,800 million for Intel.
