Architecture Differences

The AMD Ryzen 7 5800H is built on the Zen 3 architecture, codenamed Cezanne, and belongs to the 5000 series. It uses a 7 nm process from TSMC with 10,700 million transistors on a 180 mm² die. The Intel Core i7-1270P uses the Alder Lake architecture, codenamed Alder Lake-P, on Intel’s 10 nm process with a 217 mm² die size. The transistor count for the Intel chip is not listed in the database.

Cache layouts differ significantly. The AMD processor has 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of shared L3 cache. The Intel processor has 80 KB of L1 per core, 1.25 MB of L2 per core, and 18 MB of shared L3 cache. This gives Intel a larger total cache pool, though AMD’s per-core L2 allocation is smaller.

Memory support also separates the two. The AMD Ryzen 7 5800H supports only DDR4 in dual-channel mode with a memory bandwidth of 68.3 GB/s. The Intel Core i7-1270P supports both DDR4 and DDR5 in dual-channel mode, though its memory bandwidth figure is not recorded. PCIe generation differs as well: AMD uses Gen 3, while Intel uses Gen 4 with 20 lanes available from the CPU.

The integrated graphics are distinct: AMD pairs its CPU with Radeon Vega 8, while Intel uses Iris Xe 96EU. Both processors are unlocked for overclocking, neither supports ECC memory, and both target the mobile market segment. The AMD chip launched on 2021-01-11, while the Intel chip launched on 2022-02-22.

Head-to-Head Benchmarks

The benchmark data shows a clear split between older and newer workloads. In Cinebench R15 multi-core, the AMD Ryzen 7 5800H dominates with a 2,005 score versus Intel’s 1,404, a 42.8% advantage. The single-core R15 test also favors AMD, with 229 points versus 198 points, a 15.7% lead. These results suggest AMD’s Zen 3 architecture scales better in that particular rendering workload.

The picture reverses in Cinebench R23. The Intel Core i7-1270P scores 13,938 in multi-core, beating AMD’s 12,091.5 by 13.2%. The single-core delta is even larger: Intel scores 1,967 versus AMD’s 1,416, a 28% gap. This indicates Intel’s newer architecture handles the more demanding R23 workload more efficiently, particularly in single-thread performance.

PassMark tests reveal where each processor excels. AMD wins 9 of the 15 head-to-head benchmarks, while Intel wins 6. AMD’s largest victories come in extended instructions (18,203 versus 10,575, a 72.1% lead), data encryption (16,962 versus 11,276, a 50.4% lead), and data compression (270,608 versus 184,917, a 46.3% lead). These are significant margins that point to AMD’s strength in compute-heavy, multi-threaded tasks.

Intel fights back in specific workloads. The PassMark physics test shows Intel at 1,120 points versus AMD’s 830, a 25.9% advantage. Prime number finding also favors Intel, with 66 points versus 49 points, a 25.8% lead. The floating-point math test is close, with AMD’s 44,479 barely edging Intel’s 43,168 by 3%.

The average benchmark scores tell a similar story. AMD’s average benchmark score is 23,277, while Intel’s is 22,502. Both processors sit at the 76th percentile against all CPUs in the database. AMD’s nearest rivals include the Intel Core Ultra 7 266V (0.1% behind) and the Intel Core i9-11900F (0.1% ahead), while Intel’s nearest rival is the Intel Core i5-13500H (0.2% ahead).

Specification Differences

The core count is the most obvious difference: 8 cores for AMD versus 12 cores for Intel, both with 16 threads. Clock speeds diverge substantially. AMD’s base clock is 3.20 GHz with a 4.40 GHz boost, while Intel runs at 2.20 GHz base and 4.80 GHz boost. The thermal design power (TDP) also differs: AMD is rated at 45 watts, Intel at 28 watts.

Process node and foundry differ. AMD uses TSMC’s 7 nm process with 10,700 million transistors on a 180 mm² die. Intel uses its own 10 nm process with a 217 mm² die and no recorded transistor count. Cache configurations are distinct, with Intel offering larger L1 (80 KB per core versus 64 KB) and L2 (1.25 MB per core versus 512 KB), plus more shared L3 (18 MB versus 16 MB).

Memory support is a key differentiator. AMD only supports DDR4, while Intel supports both DDR4 and DDR5. AMD’s memory bandwidth is recorded at 68.3 GB/s; Intel’s is not listed. PCIe generation differs: AMD has Gen 3, Intel has Gen 4 with 20 CPU lanes. The integrated graphics are different models: Radeon Vega 8 for AMD, Iris Xe 96EU for Intel.

The socket and part numbers are unique to each platform. AMD uses AMD Socket FP6 with part number 100-000000295, while Intel uses Intel BGA 1744 with part number SRLD7. Release dates differ by over a year: AMD launched on 2021-01-11, Intel on 2022-02-22.

The Verdict

The data does not declare a single winner; it declares a workload-dependent split. The AMD Ryzen 7 5800H wins 9 benchmarks, while the Intel Core i7-1270P wins 6. The AMD chip’s wins are often by large margins, such as 72.1% in extended instructions and 50.4% in data encryption. The Intel chip’s wins are typically more moderate, though its 28% single-core Cinebench R23 lead is substantial.

For users prioritizing raw multi-threaded compute, particularly in encryption, compression, or extended instruction workloads, the AMD Ryzen 7 5800H is the stronger choice. Its 42.8% lead in Cinebench R15 multi-core and 46.3% lead in data compression show that it handles parallel workloads with authority. The PassMark multi-thread score of 20,789 versus 16,957, a 22.6% advantage, reinforces this.

For users prioritizing single-thread responsiveness and newer rendering workloads, the Intel Core i7-1270P is better. Its Cinebench R23 single-core score of 1,967 versus 1,416 is a decisive 28% margin. The PassMark single-thread score of 3,354 versus 3,021 adds another 9.9% win. The physics test also favors Intel by 25.9%, which may matter for certain simulation tasks.

Both processors sit at the 76th percentile in the database, meaning they occupy similar overall performance tiers. The AMD chip’s average benchmark score of 23,277 is 3.4% higher than Intel’s 22,502. However, the Intel chip achieves this with a 28-watt TDP versus AMD’s 45-watt TDP, which could be relevant in thermally constrained laptops.

Where Each One Wins

AMD Ryzen 7 5800H wins in:

• Multi-threaded rendering in Cinebench R15: 42.8% ahead
• Data compression: 46.3% ahead with a score of 270,608
• Data encryption: 50.4% ahead with a score of 16,962
• Extended instruction workloads: 72.1% ahead
• Integer math: 28.2% ahead
• Random string sorting: 37% ahead
• PassMark multi-thread overall: 22.6% ahead

Intel Core i7-1270P wins in:

• Cinebench R23 multi-core: 13.2% ahead with a score of 13,938
• Cinebench R23 single-core: 28% ahead with a score of 1,967
• PassMark single-thread: 9.9% ahead with a score of 3,354
• PassMark physics: 25.9% ahead with a score of 1,120
• Prime number finding: 25.8% ahead

The practical takeaway: choose AMD for heavy parallel compute, encryption, and compression tasks, especially if power draw is not the primary constraint. Choose Intel for single-thread responsiveness, physics simulations, and newer multi-core rendering tests, particularly in laptops where the 28-watt TDP may allow thinner cooling solutions.
