AMD Ryzen 7 5800X vs Intel Core i7-12650H Comparison

The AMD Ryzen 7 5800X and the Intel Core i7-12650H are two very different processors serving two different markets: the former is a desktop chip, the latter a mobile part. The benchmark data shows the Ryzen 7 5800X wins 10 of the 15 head-to-head tests, while the Core i7-12650H takes 5. The 5800X dominates in multi-core and throughput-heavy workloads, often by large margins (40.9% in Cinebench R15 multi-core, 50.9% in data encryption). The 12650H counters in a few specific single-threaded and floating-point tasks, but its wins are narrow (2.7% in single-thread, 4.2% in floating-point math). The verdict is clear: the 5800X is the stronger processor by overall average benchmark score (29123 vs 28815) and percentile ranking (81st vs 80th), though the mobile chip’s efficiency and integrated graphics make it the sensible pick for laptop builds.

The Verdict

For desktop users who prioritize raw compute, the AMD Ryzen 7 5800X is the clear choice. Its average benchmark score of 29123 places it in the 81st percentile of all CPUs, and it outperforms the Core i7-12650H in nearly every multi-threaded test. The 5800X leads by 28.2% in Cinebench R23 multi-core (15476 vs 12074) and by 26.3% in PassMark multithread (27732 vs 21962). It also wins decisively in integer math (94969 vs 73641, a 29% lead) and data compression (345414 vs 250026, a 38.2% lead). If you are building a desktop workstation or gaming rig and need sustained multi-core muscle, the 5800X is the data-supported pick.

The Intel Core i7-12650H, by contrast, is a mobile processor designed for laptops. It wins the single-core Cinebench R23 test (1763 vs 1574.5, a 10.7% lead) and edges out the 5800X in PassMark single-thread (3539 vs 3445, a 2.7% lead). It also wins in floating-point math (54934 vs 52639, a 4.2% lead) and physics (1430 vs 1364, a 4.6% lead). These wins are modest, and the 12650H’s overall average score of 28815 trails the 5800X by about 1.1%. However, the 12650H has a 45W TDP versus the 5800X’s 105W, and it includes integrated UHD Graphics, so it is the appropriate choice for a thin-and-light laptop where battery life and an iGPU matter more than peak throughput.

The data does not support picking the 12650H for heavy desktop workloads. Its 5 wins are all narrow single-thread or niche floating-point gains, while its 10 losses include several blowouts (52.7% in extended instructions, 50.9% in encryption, 40.9% in R15 multi-core). For anyone who can tolerate a desktop form factor, the 5800X is the performance winner. For mobile users, the 12650H is the only option here, and its performance is competitive in single-thread tasks but clearly behind in multi-threaded ones.

Architecture Differences

The two chips diverge fundamentally in architecture, process, and target platform. The AMD Ryzen 7 5800X uses the Zen 3 architecture (codename Vermeer), built on a 7 nm process at TSMC. It has 8 cores and 16 threads, with a base clock of 3.80 GHz and a boost clock of 4.70 GHz. The 5800X features a 32 MB L3 cache and per-core L1 (64 KB) and L2 (512 KB) caches. It supports DDR4 memory in dual-channel mode with a memory bandwidth of 51.2 GB/s and includes ECC memory support. The chip uses AMD Socket AM4 and has a 105W TDP. It is a desktop part with no integrated graphics, and its multiplier is unlocked for overclocking.

The Intel Core i7-12650H uses the Alder Lake architecture (codename Alder Lake-H), built on a 10 nm process at Intel. It has 10 cores and 16 threads, with a base clock of 2.30 GHz and a boost clock of 4.70 GHz. Its cache layout differs: 80 KB L1 per core, 1.25 MB L2 per core, and 24 MB of shared L3. It supports both DDR4 and DDR5 memory in dual-channel mode, but the FACT PACK does not list a memory bandwidth figure for it. ECC memory is not supported. The 12650H uses Intel BGA 1744 socket, has a 45W TDP, and includes integrated UHD Graphics. It is a mobile part with a locked multiplier. The die sizes also differ sharply: the 5800X has a 74 mm² die with 4,150 million transistors, while the 12650H has a 217 mm² die (transistor count not listed). Both support PCIe Gen 4 with 20 lanes (CPU only).

The architectural trade-offs are evident: the 5800X’s larger L3 cache (32 MB vs 24 MB) and higher base clock (3.80 vs 2.30 GHz) contribute to its multi-threaded dominance, while the 12650H’s higher single-core boost behavior (matching 4.70 GHz) helps it win single-thread tests. The 12650H’s hybrid architecture (10 cores) does not translate into a thread advantage, as both chips have 16 threads.

Head-to-Head Benchmarks

The AMD Ryzen 7 5800X dominates the head-to-head results, winning 10 of 15 tests. Its most crushing victory is in PassMark extended instructions, where it scores 23573 versus the 12650H’s 15438, a 52.7% lead. Data encryption is nearly as lopsided: 21191 vs 14041, a 50.9% margin. In Cinebench R15 multi-core, the 5800X scores 2608.5 against 1851.5, a 40.9% advantage. Data compression also favors AMD heavily (345414 vs 250026, 38.2%), as does prime number finding (124 vs 91, 36.3%) and random string sorting (35401 vs 26591, 33.1%). Integer math shows a 29% lead (94969 vs 73641). Cinebench R23 multi-core sees the 5800X ahead by 28.2% (15476 vs 12074), and PassMark multithread shows a 26.3% gap (27732 vs 21962). Even in single-core Cinebench R15, the 5800X wins, scoring 265.5 against 250, a 6.2% margin.

The Intel Core i7-12650H wins the remaining 5 tests, but by smaller margins. Its best result is Cinebench R23 single-core, where it scores 1763 versus 1574.5, a 10.7% lead. In PassMark physics, it wins 1430 to 1364 (4.6%). Floating-point math goes to Intel by 4.2% (54934 vs 52639). The two single-thread tests (PassMark single_thread and singlethread) both go to the 12650H by 2.7% (3539 vs 3445). These wins are consistent with a mobile chip that prioritizes bursty single-thread performance, but they do not offset the scale of AMD’s multi-threaded victories. The aggregate picture is clear: the 5800X is roughly 1% ahead in average score (29123 vs 28815) and holds a 10-to-5 win record, with the average margin of its wins (around 35%) far exceeding the average margin of Intel’s wins (around 5%).
