AMD Ryzen 7 6800H vs Intel Core i5-12450HX Comparison

Head-to-Head Benchmarks

The benchmark data records 15 direct comparisons between the Intel Core i5-12450HX and the AMD Ryzen 7 6800H. The AMD part wins 11 of those tests, while the Intel chip takes 4. The overall average benchmark score favors AMD at 25201 versus 24576 for Intel, a difference of roughly 2.5%. Both processors sit at the 77th percentile among all CPUs in the database, so the two are close in overall standing despite the per-test differences.

The most striking margin comes in Cinebench R23 single-core, where the Intel Core i5-12450HX scores 2119 against 1542 for the AMD Ryzen 7 6800H. That is a 37.4% advantage for Intel, the largest delta in either direction across the entire head-to-head set. This result stands out because the AMD chip has a higher boost clock, yet the Intel part delivers substantially better single-thread performance in this test. The Intel advantage extends to PassMark single-thread tests as well, with scores of 3340 versus 3212, a 4% lead. PassMark physics also goes to Intel, 1086 to 1046, a 3.8% margin.

The AMD Ryzen 7 6800H dominates the multi-threaded and throughput-oriented workloads. In Cinebench R15 multicore, AMD scores 2136 against 1512 for Intel, a 29.2% deficit for the Intel part. Cinebench R23 multicore shows a similar pattern: 13094 for AMD versus 11390 for Intel, a 13% gap. PassMark multithread favors AMD at 23060 versus 18274, a 20.8% difference. The largest AMD wins come in PassMark data encryption (18260 vs 12110, a 33.7% gap) and PassMark integer math (85397 vs 57189, a 33% gap). PassMark extended instructions also heavily favor AMD at 20114 versus 13832, a 31.2% margin. Data compression goes to AMD by 25.3% (293929 vs 219707), random string sorting by 24% (30668 vs 23306), and floating point math by 10.1% (47989 vs 43126). The smallest AMD win is in PassMark find prime numbers, 57 to 54, a 5.3% edge.

The pattern is clear: Intel wins decisively in single-core Cinebench and narrowly in PassMark single-thread, while AMD wins everything else, often by substantial margins. The AMD chip has 16 threads versus 12 for Intel, which helps explain the multicore dominance, but the integer and encryption gaps are larger than thread count alone would suggest.

Architecture Differences

The two processors come from different design philosophies. The Intel Core i5-12450HX uses Alder Lake architecture, specifically the Alder Lake-HX variant, built on Intel's 10 nm process with a die size of 215 mm². The AMD Ryzen 7 6800H uses Zen 3+ architecture, codenamed Rembrandt, built on TSMC's 6 nm process with a die size of 208 mm². The AMD chip is slightly smaller despite using a newer process node, and it is produced by a different foundry.

Core and thread counts differ meaningfully. Both have 8 cores, but the Intel part supports 12 threads while the AMD part supports 16. This indicates that the Intel chip uses a hybrid arrangement with some cores lacking hyper-threading, while the AMD chip has symmetric multithreading across all cores. The cache layouts reinforce the architectural split. Intel provides 80 KB of L1 per core and 1.25 MB of L2 per core, with 12 MB of shared L3. AMD provides 64 KB of L1 per core and 512 KB of L2 per core, but a larger 16 MB of shared L3. The AMD chip has more total cache at the L3 level, while Intel has more per-core L1 and L2.

Clock speeds favor AMD on paper. The Ryzen 7 6800H has a base clock of 3.20 GHz and a boost clock of 4.70 GHz. The Intel Core i5-12450HX has a base clock of 2.40 GHz and a boost clock of 4.40 GHz. Despite the lower clocks, the Intel part wins single-core Cinebench R23 by a wide margin, suggesting that the Alder Lake architecture has a significant IPC advantage in that workload. The AMD chip compensates with higher clocks and more threads in multi-threaded tests.

Memory support differs as well. The Intel part supports both DDR4 and DDR5, while the AMD part supports DDR5 only. Both use dual-channel memory buses. The AMD chip has a recorded memory bandwidth of 76.8 GB/s, while no bandwidth figure is recorded for the Intel part. PCIe connectivity is also different: Intel uses Gen 5 with 20 lanes (CPU only), while AMD uses Gen 4 with the same 20 lanes. The integrated graphics differ, with Intel offering UHD Graphics 710 and AMD offering Radeon 680M. The AMD integrated solution is generally considered more capable, though no benchmark data for graphics is recorded here.

The Intel part has an unlocked multiplier and a specified launch MSRP of $284, while the AMD part has a locked multiplier and no recorded launch MSRP. The Intel chip is listed with production status Active and a release date of 2022-05-09, while the AMD chip also has Active production status but no release date recorded. Both are mobile market segments and neither supports ECC memory.

The Verdict

The data points to a clear split based on workload type. For single-threaded tasks, particularly those that resemble Cinebench R23 single-core, the Intel Core i5-12450HX is the stronger choice. Its 37.4% lead in that specific test is the largest single advantage recorded in either direction. The Intel chip also edges out the AMD part in PassMark single-thread and physics tests, so users who prioritize lightly threaded applications should favor Intel.

For multi-threaded workloads, the AMD Ryzen 7 6800H is consistently ahead. The 16-thread configuration gives it an advantage in Cinebench R15 multicore (29.2% ahead), Cinebench R23 multicore (13% ahead), and PassMark multithread (20.8% ahead). The AMD chip also dominates in data encryption, integer math, extended instructions, and data compression, with margins ranging from 25.3% to 33.7%. These are substantial wins that affect real-world productivity tasks.

The overall average benchmark score favors AMD at 25201 versus 24576, a 2.5% difference. Both chips sit at the same 77th percentile, meaning they are comparable in the broader CPU landscape. The AMD Ryzen 7 6800H also has a higher base clock (3.20 GHz vs 2.40 GHz) and boost clock (4.70 GHz vs 4.40 GHz), plus a larger L3 cache (16 MB vs 12 MB) and a smaller process node (6 nm vs 10 nm).

The Intel chip has the advantages of an unlocked multiplier, broader memory support (DDR4 and DDR5 versus DDR5 only), and PCIe Gen 5 connectivity. It also has a recorded launch MSRP of $284, while the AMD part has no recorded MSRP. For users who need maximum single-core performance or prefer the flexibility of DDR4 memory and an unlocked multiplier, the Intel part is the logical pick. For users who run multi-threaded workloads, encryption, compression, or integer-heavy tasks, the AMD Ryzen 7 6800H is clearly superior based on the recorded data.
