AMD Ryzen 7 7435HS vs Intel Core i7-12700H Comparison

Head-to-Head Benchmarks

The benchmark data reveals a genuinely split personality between these two mobile processors, with each claiming victory in distinct workload categories. The Intel Core i7-12700H wins 14 of the 23 head-to-head comparisons, while the AMD Ryzen 7 7435HS takes 9 — but the magnitude of those wins tells a more complex story than the raw tally suggests.

Intel’s most decisive victories come in compute-heavy integer and physics workloads. The 3dmark_find_prime_numbers test shows the i7-12700H scoring 94 versus the Ryzen’s 54, a 74.1% advantage that points to Intel’s hybrid architecture excelling at latency-sensitive prime calculation. Similarly, passmark_physics shows Intel at 1512 against AMD’s 991, a 52.6% lead. Floating-point math follows the same pattern: Intel’s 65075 score beats AMD’s 48863 by 33.2%. These aren’t marginal differences — they represent fundamentally different execution strengths.

The Cinebench R15 multicore result amplifies this narrative. Intel scores 2604.6 versus AMD’s 2003, a 30% advantage. That’s the single largest multicore delta in the entire benchmark suite, and it suggests the i7-12700H’s 14 cores and 20 threads are being leveraged effectively in this particular rendering workload. The R20 multicore test shows a narrower but still Intel-favorable 6.9% gap (8921 vs 8346).

Single-threaded performance splits in unexpected ways. The 3dmark_single_thread test favors Intel at 949 versus 888, a 6.9% edge. Passmark_single_thread shows Intel at 3535 against AMD’s 3167, an 11.6% advantage. Yet Cinebench R15 single-core tells the opposite story: AMD wins 282 to 256, a 9.2% margin. Cinebench R23 single-core is where AMD’s biggest single-thread win appears — 2805 versus 1782, a staggering 36.5% lead. This inconsistency across different single-threaded benchmarks suggests the two architectures respond very differently to the specific instruction mixes in each test.

AMD’s multicore wins are concentrated in 3DMark’s thread-scaling tests. The 3dmark_8_threads result shows AMD at 5813 versus Intel’s 4951, a 14.8% advantage. The 16-thread test gives AMD 6915 against Intel’s 6460, a 6.6% lead. But at max threads, Intel edges ahead 6941 to 6900, a marginal 0.6% win. This pattern implies AMD’s 8 cores with 16 threads scale more efficiently up to 16 threads, but Intel’s additional cores help it catch up when all 20 threads are utilized.

Cinebench R23 multicore delivers AMD’s most impressive overall result: 19873 versus Intel’s 16307.5, a 17.9% advantage. This directly contradicts the R15 multicore result where Intel led by 30%. The discrepancy between Cinebench versions is striking and suggests workload-specific optimization differences between the two CPUs.

Data-oriented tasks split more evenly. Passmark data compression favors AMD slightly (310038 vs 300594, a 3% edge), and data encryption also goes AMD’s way (18648 vs 17575, 5.8% ahead). Extended instructions show AMD’s biggest data-processing win at 21690 versus 17886, a 17.5% margin. Intel fights back in random string sorting (33449 vs 31827, 5.1% ahead) and integer math (90106 vs 85274, 5.7% ahead). The passmark_multithread benchmark gives Intel a 9.5% win at 25615 versus 23393.

Architecture Differences

The two processors represent fundamentally different design philosophies. The Intel Core i7-12700H uses Alder Lake architecture built on Intel’s 10 nm process, fabricated in-house by Intel. It employs a hybrid core layout with 14 cores and 20 threads. The AMD Ryzen 7 7435HS uses Zen 3+ architecture on TSMC’s 6 nm process, with 8 cores and 16 threads in a traditional uniform design.

Cache hierarchies differ substantially. Intel provides 80 KB of L1 cache per core, 1.25 MB of L2 per core, and 24 MB of shared L3 cache. AMD counters with 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of shared L3. Intel’s larger L3 cache could explain its advantages in cache-sensitive workloads like physics calculations and prime number finding.

Process node differences are notable: Intel uses 10 nm while AMD uses 6 nm from TSMC. Die sizes are similar (Intel at 217 mm², AMD at 210 mm²), but the transistor density on TSMC’s 6 nm node likely explains how AMD fits its design into a comparable area. Both processors use dual-channel memory, but Intel supports both DDR4 and DDR5 while AMD supports only DDR5. AMD’s memory bandwidth is specified at 76.8 GB/s; Intel’s is not listed.

Both use PCIe Gen 4 with 20 lanes from the CPU. Intel integrates Iris Xe graphics with 96 execution units, while AMD lists no integrated graphics — a significant difference for systems that might run without a discrete GPU. Both are locked processors (multiplier not unlocked) and both have a 45W TDP. Intel uses the BGA 1744 socket; AMD uses the FP7 socket.

ECC memory support differs: AMD supports ECC while Intel does not. This could matter for specific professional or server-adjacent mobile workloads. The base and boost clocks also differ: Intel runs at 2.30 GHz base and 4.70 GHz boost, while AMD runs higher at 3.10 GHz base but lower at 4.50 GHz boost.

The Verdict

The data paints a picture of two processors optimized for different priorities. The Intel Core i7-12700H is the better choice for workloads that involve integer math, physics calculations, floating-point operations, and general multithreaded productivity. Its 14-core design with 20 threads gives it a structural advantage in tasks that can utilize many threads simultaneously, as evidenced by its 30% lead in Cinebench R15 multicore and 9.5% win in passmark_multithread.

The AMD Ryzen 7 7435HS excels in specific rendering workloads and data processing tasks. Its 17.9% victory in Cinebench R23 multicore and 36.5% win in Cinebench R23 single-core suggest that newer rendering engines and certain single-threaded applications respond exceptionally well to Zen 3+ architecture. Its 8-core design with 16 threads proves more efficient in the 3DMark thread-scaling tests up to 16 threads.

Users who prioritize physics simulations, scientific computing with floating-point math, or tasks involving prime number calculations should lean toward the i7-12700H. Those who work with modern rendering engines, data compression, encryption, or extended instruction sets may find the Ryzen 7 7435HS more responsive. The overall percentile rankings (79th vs 78th) and average benchmark scores (26717 vs 26402) indicate these are closely matched processors that serve different use-case profiles rather than one being categorically superior.
