AMD Ryzen AI 5 435 vs Intel Core i5-12600KF Comparison

Head-to-Head Benchmarks

The benchmark data is unambiguous: the Intel Core i5-12600KF wins every single head-to-head comparison against the AMD Ryzen AI 5 435. Out of 15 recorded tests, the Intel part takes all 15, with the AMD processor's deficits ranging from a modest 4.9% to a crushing 51.5%. This is not a close contest by any measure, and the gap is most pronounced in multi-threaded workloads where the Intel chip's additional cores and threads come into play.

The largest margin of victory for the Intel Core i5-12600KF appears in Cinebench R23 multi-core, where it scores 23391 against the AMD's 11333, a 51.5% advantage. This is the single biggest delta in the entire comparison, and it reflects the fundamental difference in core counts and thread counts between the two processors. The Intel chip also dominates Cinebench R15 multi-core, scoring 2357 versus 1686, a 28.5% lead. For single-core performance, the Intel part remains ahead but by a smaller margin: in Cinebench R23 single-core, it scores 3302 against 1816, a 45% lead, while in Cinebench R15 single-core it scores 332 against 260, a 21.7% advantage.

PassMark results tell the same story. In data compression, the Intel chip scores 343231 versus 225374, a 34.3% lead. Data encryption shows a 39.8% gap, with Intel at 18445 and AMD at 11110. Extended instructions favor Intel by 26.4%, with scores of 22003 and 16197 respectively. The floating point math test gives Intel a 39.4% edge (67074 versus 40627), while integer math shows a 30.5% gap (87830 versus 61026). Find prime numbers, a test that stresses raw integer throughput, has Intel at 91 versus AMD's 58, a 36.3% difference.

The closest result in the entire dataset is the PassMark single-thread test, where the Intel Core i5-12600KF scores 3925 and the AMD Ryzen AI 5 435 scores 3734, a margin of just 4.9%. This tells a meaningful story: despite the Intel chip's commanding leads elsewhere, the AMD processor's Zen 5 architecture is competitive on a per-thread basis. The single-core Cinebench results contradict this somewhat, showing a much larger gap, but the PassMark single-thread metric suggests the AMD part is not far behind in lightly threaded scenarios.

Multithreaded PassMark results reinforce the pattern: Intel wins 27575 to 19000, a 31.1% lead. Physics simulation favors Intel by 30.1% (1539 versus 1075), and random string sorting also favors Intel by 30.1% (35602 versus 24891). Across every category, the Intel Core i5-12600KF is the faster processor, often by a wide margin, and the AMD Ryzen AI 5 435 never manages to claim a single benchmark victory in the head-to-head set.

Where Each One Wins

Given that the Intel Core i5-12600KF wins all 15 head-to-head benchmarks, there is no workload category in the recorded data where the AMD Ryzen AI 5 435 comes out ahead. The practical question is not which processor wins, but how close the AMD part can get and in which specific tests the gap narrows.

The AMD Ryzen AI 5 435 is least disadvantaged in single-threaded performance. The PassMark single-thread test shows only a 4.9% gap, which is the smallest delta in the entire comparison. For users whose workloads are dominated by lightly threaded applications, the AMD processor would deliver nearly comparable responsiveness, though the Intel chip still holds the edge.

The Intel Core i5-12600KF is strongest in multi-threaded and compute-heavy tasks. Its 51.5% lead in Cinebench R23 multi-core is the standout result, and its 39.8% advantage in data encryption and 39.4% lead in floating point math indicate that heavily parallel workloads, rendering tasks, and scientific computing would all see substantial benefits from choosing the Intel part.

The Intel chip also dominates in memory bandwidth sensitive workloads like data compression, where it leads by 34.3%. The AMD processor's 4 MB of L3 cache is far smaller than the Intel chip's 20 MB shared L3 cache, which likely contributes to these deficits in cache-sensitive workloads. The AMD part does include ECC memory support, a feature the Intel chip lacks, which could matter for specific reliability-focused use cases, but this is a feature difference, not a performance win.

In summary, the AMD Ryzen AI 5 435's best case is in single-threaded tasks where the gap to Intel narrows to under 5%. The Intel Core i5-12600KF's best case is everywhere else, particularly in multi-core rendering and compute workloads where its lead frequently exceeds 30%.

Architecture Differences

The two processors come from fundamentally different design philosophies and market segments. The AMD Ryzen AI 5 435 is a mobile processor built on TSMC's 4 nm process, using the Zen 5 architecture with the codename Gorgon Point. It belongs to the Ryzen AI 400 generation, which combines Zen 5 and Zen 5c cores. The Intel Core i5-12600KF is a desktop processor built on Intel's 10 nm process, using the Alder Lake architecture with the codename Alder Lake-S, and belongs to the Core 12th Gen family.

Core and thread counts differ significantly. The AMD part has 6 cores and 12 threads, while the Intel part has 10 cores and 16 threads. This four-core and four-thread advantage is the primary driver of the Intel chip's multi-threaded dominance. The AMD processor's base clock is 2.00 GHz with a boost clock of 4.50 GHz, while the Intel chip runs at a 3.70 GHz base clock and boosts to 4.90 GHz. The Intel part's higher clocks contribute to its single-thread advantages, though the AMD chip's Zen 5 cores narrow the gap.

Cache configurations are starkly different. The AMD Ryzen AI 5 435 has 80 KB of L1 cache per core, 1 MB of L2 cache per core, and only 4 MB of L3 cache. The Intel Core i5-12600KF also has 80 KB of L1 cache per core but has 1.25 MB of L2 cache per core and 20 MB of shared L3 cache. The Intel chip's five times larger L3 cache is a major architectural advantage, particularly for workloads that benefit from large shared caches.

Memory support also differs. The AMD processor supports DDR5 and LPDDR5X memory with dual-channel configuration and a measured memory bandwidth of 89.6 GB/s. It also supports ECC memory. The Intel chip supports both DDR4 and DDR5 in dual-channel configuration, but its memory bandwidth is not recorded in the database, and it does not support ECC memory. The Intel part offers more PCIe lanes: 20 lanes of Gen 4 versus the AMD part's 14 lanes of Gen 4.

The AMD Ryzen AI 5 435 includes integrated Radeon 840M graphics, while the Intel Core i5-12600KF has no integrated graphics at all, as indicated by the "KF" suffix which denotes a chip without graphics. The Intel chip is multiplier unlocked, allowing overclocking, while the AMD part is not. The Intel chip has a die size of 215 mm², while the AMD part's die size is not recorded.

Power characteristics differ dramatically. The AMD processor has a TDP of 28 watts, while the Intel chip has a TDP of 125 watts. This reflects the AMD part's mobile orientation and the Intel chip's desktop orientation. The AMD socket is FP8, while the Intel chip uses Socket 1700.

The Verdict

The data is decisive: the Intel Core i5-12600KF is the faster processor in every measured benchmark. Its 10 cores and 16 threads, higher clock speeds, larger 20 MB L3 cache, and desktop-class power envelope give it overwhelming advantages in multi-threaded workloads, with leads of 51.5% in Cinebench R23 multi-core, 39.8% in data encryption, and 39.4% in floating point math. Even in single-threaded tasks, where the AMD Zen 5 architecture is most competitive, the Intel chip still wins, though by a narrower 4.9% in the PassMark single-thread test.

The AMD Ryzen AI 5 435 is not without its merits. It is a mobile processor with a 28 watt TDP, which suggests far lower power consumption than the Intel chip's 125 watt TDP. It includes integrated Radeon 840M graphics, which the Intel chip lacks entirely. It supports ECC memory, which the Intel chip does not. And its 4 nm TSMC process node is more advanced than Intel's 10 nm node. For users who need a processor with integrated graphics, ECC memory support, and low power draw, the AMD part has clear qualitative advantages.

However, the benchmark results do not support choosing the AMD Ryzen AI 5 435 on performance grounds. The Intel Core i5-12600KF is faster in every single test, and its 79th percentile ranking versus all CPUs, compared to the AMD part's 80th percentile, shows that both processors sit in a similar overall performance tier despite the Intel chip's head-to-head dominance. The Intel chip's nearest rivals include the AMD Ryzen 7 5800X3D with an average score of 27896 and a delta of -0.3%, while the AMD part's nearest rivals include the Intel Core i5-13490F with an average score of 28185 and a delta of -0.2%.

The verdict is straightforward: users who prioritize raw performance in multi-threaded and single-threaded workloads should choose the Intel Core i5-12600KF. Users who prioritize integrated graphics, ECC memory support, low power consumption, and a mobile form factor should choose the AMD Ryzen AI 5 435, accepting that the performance trade-off is substantial.
