Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 5 8600G uses the Zen 4 architecture on a 4 nm TSMC process, with a die size of 178 mm² and 25,000 million transistors. It has 6 cores and 12 threads, with base and boost clocks of 4.30 GHz and 5.00 GHz respectively. The cache layout includes 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3 cache.

The Intel Core Ultra 9 285 uses the Arrow Lake architecture on a 3 nm TSMC process, with a die size of 243 mm² and 17,800 million transistors. It features 24 cores and 24 threads, with base and boost clocks of 2.50 GHz and 5.60 GHz. The cache hierarchy is substantially larger: 192 KB of L1 per core, 3 MB of L2 per core, and 36 MB of shared L3 cache.

The transistor count difference is notable. The AMD chip packs 25,000 million transistors into a smaller die, while the Intel chip uses fewer transistors (17,800 million) across a larger die. This reflects the different core counts and the inclusion of a more powerful integrated graphics unit on the AMD side (Radeon 760M) versus the Intel Arc Xe-LPG Graphics 64EU.

Memory support differs in bandwidth and error correction. Both support DDR5 with dual-channel memory buses, but the Intel chip has a higher theoretical bandwidth at 102.4 GB/s versus 83.2 GB/s for the AMD. The Intel processor also supports ECC memory, while the AMD does not. PCIe connectivity differs as well: the AMD uses Gen 4 with 20 lanes, while the Intel uses Gen 5 with 20 lanes.

The Intel processor has a locked multiplier, while the AMD chip is unlocked. The Intel part uses Intel Socket 1851, and the AMD uses AMD Socket AM5. The AMD chip was released on 2024-01-07, while the Intel chip carries a release date of 2024-12-31.

Head-to-Head Benchmarks

The Cinebench suite shows consistent margins across all versions. In Cinebench R15 multicore, the Intel scores 4933 against 2167 for the AMD, a delta of -56.1 percent. The single-core R15 result is 696 versus 305, a -56.2 percent delta. Cinebench R20 multicore shows 20556 versus 9031 (-56.1 percent), and R20 single-core shows 2901 versus 1274 (-56.1 percent). Cinebench R23 multicore shows 48945 versus 21503 (-56.1 percent), and R23 single-core shows 6909 versus 3035 (-56.1 percent).

The consistency of the -56.1 percent delta across all Cinebench versions indicates a scaling factor that remains stable regardless of workload generation. The multicore and single-core deltas are nearly identical, which suggests the Intel advantage comes from architectural efficiency rather than raw core count alone, since the single-core tests would not benefit from the 24-core count.
