Architecture Differences

The AMD Ryzen Embedded 9600X uses the Granite Ridge codename and belongs to the Ryzen Embedded generation built on Zen 5 (Granite Ridge). It has 8,315 million transistors on a 70.6 mm² die. The Intel Core Ultra 7 255H uses the Arrow Lake-H codename and belongs to the Core Ultra Series 2 generation. Its transistor count and die size are not recorded in the database.

The cache structures differ significantly. The AMD part has 80 KB of L1 cache per core, 1 MB of L2 cache per core, and 32 MB of shared L3 cache. The Intel part has 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 24 MB of shared L3 cache. The Intel part's larger per-core L1 and L2 allocations reflect a different cache hierarchy design, while the AMD part's larger shared L3 suggests a focus on pooled data access across its six cores.

Memory support diverges. The AMD part supports DDR5 only, with a dual-channel memory bus and 89.6 GB/s bandwidth. The Intel part supports both DDR5 and LPDDR5X, also dual-channel, with 102.4 GB/s bandwidth. The Intel part's higher memory bandwidth aligns with its mobile positioning, where LPDDR5X is common for power efficiency.

PCIe lane counts differ. The AMD part provides 24 PCIe Gen 5 lanes (CPU only). The Intel part provides 20 PCIe Gen 5 lanes (CPU only). The AMD part offers four more lanes, which matters for desktop expansion. The integrated graphics also differ: the AMD part uses Radeon Graphics, while the Intel part uses Arc Graphics 140T.

The multiplier unlock status is a clear distinction. The AMD part has an unlocked multiplier, enabling overclocking. The Intel part has a locked multiplier, preventing user overclocking. The AMD part uses AMD Socket AM5, while the Intel part uses Intel BGA 2049, meaning the Intel part is soldered to the board and not socketed.

Head-to-Head Benchmarks

The Intel Core Ultra 7 255H leads in every recorded benchmark category. The largest absolute gaps appear in multicore and throughput-oriented tests. In Cinebench R23 multicore, the Intel part scores 9240, and the AMD part has no recorded score. The same applies to Cinebench R20 multicore at 6381 and Cinebench R15 multicore at 1515. Without AMD scores, the comparison relies on the Intel part's internal consistency across tests.

The Geekbench multicore result for the Intel part is 14024, and the single-core result is 2335. The PassMark multithread score of 30703 and single-thread score of 4317 both indicate strong performance in their respective categories. The PassMark data compression score of 298850 is the highest recorded value across all PassMark entries for the Intel part, suggesting particular strength in compression workloads. Data encryption at 23395 and extended instructions at 23755 show balanced performance in security and SIMD-oriented tasks.

The nearest rivals for the Intel part provide context. The AMD Ryzen 5 240 has an average score of 33542, which is 0% different from the Intel part's 33537. The AMD Ryzen 7 8840HS averages 33667, which is 0.4% higher than the Intel part. The AMD Ryzen 5 7645HX also averages 33668, 0.4% higher. The Intel Core i5-12600HX averages 33375, which is 0.5% lower than the Intel part. These deltas show the Intel Core Ultra 7 255H sits within a tight cluster of comparable mobile processors, with no rival exceeding it by more than 0.4% in average score.

The AMD Ryzen Embedded 9600X has no benchmark scores, no average benchmark score, and no nearest rivals in the database. Its percentile ranking of 50 places it at the median of all CPUs, while the Intel part ranks at the 83rd percentile. The absence of recorded benchmarks for the AMD part means the head-to-head comparison is asymmetric: the Intel part's scores stand alone, and the AMD part's performance must be inferred from its architectural specifications rather than direct measurements.
