AMD Ryzen AI 5 435 vs Intel Core 9 273PTE Comparison

Architecture Differences

The AMD Ryzen AI 5 435 and Intel Core 9 273PTE represent two fundamentally different design philosophies within the mobile and desktop segments. The AMD part is built on the Zen 5 architecture using TSMC's 4 nm process, part of the Gorgon Point codename family within the Ryzen AI 400 generation, which mixes Zen 5 and Zen 5c cores. It features 6 cores and 12 threads, a base clock of 2.00 GHz, and a boost clock of 4.50 GHz. The processor is rated at 28 W TDP, targets the mobile market on AMD Socket FP8, and includes Radeon 840M integrated graphics. The Intel part, by contrast, uses the Bartlett Lake codename from the Core 9 generation, built on Intel's 10 nm process. It offers 12 cores and 24 threads, with a lower base clock of 1.40 GHz but a significantly higher boost clock of 5.50 GHz. Its TDP is 45 W, and it is a desktop part on Intel Socket 1700 with UHD Graphics 730.

The cache structures differ substantially. The AMD processor provides 80 KB of L1 per core and 1 MB of L2 per core, with only 4 MB of L3 cache. The Intel processor also has 80 KB of L1 per core but doubles the L2 to 2 MB per core, and its L3 cache is a shared 36 MB pool. That difference in L3 capacity is one of the largest architectural gaps between the two parts, and it directly influences multi-threaded and cache-sensitive workloads. Memory support also diverges: the AMD chip supports DDR5 and LPDDR5X, while the Intel chip supports both DDR4 and DDR5. Both use dual-channel memory buses with identical 89.6 GB/s bandwidth, and both support ECC memory. PCIe connectivity differs as well, with AMD offering Gen 4 with 14 CPU lanes and Intel offering Gen 5 with 16 CPU lanes.

The Intel part also carries a launch MSRP of $549, while the AMD part has no recorded launch MSRP in the database. Both processors are marked as production-active, with the AMD release date recorded as January 2026 and the Intel release date as March 2026. Neither processor has an unlocked multiplier, so overclocking headroom is not part of the official specification.

Head-to-Head Benchmarks

The Intel Core 9 273PTE dominates the multi-core and compute-heavy workloads in the recorded data. In Cinebench R23 multi-core, the Intel part scores 20445 against the AMD part's 11333, a delta of -44.6% from the AMD perspective, meaning the Intel chip is roughly 80% faster in that test. The Cinebench R15 multi-core test shows a narrower gap: Intel scores 2060 versus AMD's 1686, a delta of -18.2%. The single-core results also favor Intel, though by smaller margins: Cinebench R23 single-core gives Intel 2886 versus AMD's 1816, a delta of -37.1%, while Cinebench R15 single-core gives Intel 290 versus AMD's 260, a delta of -10.3%.

PassMark workloads reinforce Intel's advantage in raw compute. The find prime numbers test is the most lopsided: Intel scores 142 versus AMD's 58, a delta of -59.2%. PassMark physics also shows a large gap, with Intel at 1917 versus AMD's 1075, a delta of -43.9%. Floating point math favors Intel 60673 to 40627, a delta of -33%, and integer math favors Intel 82411 to 61026, a delta of -25.9%. Data encryption is another clear Intel win: 14253 versus 11110, a delta of -22.1%. PassMark multithread shows Intel at 24054 versus AMD's 19000, a delta of -21%. Data compression gives Intel 258704 versus AMD's 225374, a delta of -12.9%, and random string sorting gives Intel 28973 versus AMD's 24891, a delta of -14.1%.

The AMD Ryzen AI 5 435 does claim three wins, and they are notable for what they reveal about its architecture. In PassMark single-thread, AMD scores 3734 versus Intel's 3433, a delta of +8.8%. The same result appears under the passmark_singlethread label, confirming the single-thread advantage. AMD also wins in extended instructions: 16197 versus Intel's 15952, a delta of +1.5%. These wins are modest in magnitude, but they indicate that the Zen 5 architecture delivers competitive per-thread performance despite having half the cores and a much smaller L3 cache. The extended instructions result is particularly interesting because it shows AMD's instruction-set efficiency can overcome Intel's larger core count in that specific workload.

Overall, the Intel part's average benchmark score is 31143, placing it in the 82nd percentile of all CPUs, while the AMD part has an average score of 28128, placing it in the 80th percentile. The Intel chip's nearest rivals include the Intel Core i7-12700F at 31081 (0.2% delta) and the AMD Ryzen 9 8945HS at 31074 (0.2% delta). The AMD chip's nearest rivals include the Intel Core i5-13490F at 28185 (-0.2% delta) and the Intel Core i5-14500T at 28065 (0.2% delta). These comparisons show that the AMD part sits in a performance tier populated by mid-range desktop and mobile chips, while the Intel part sits among higher-end desktop parts.

Specification Differences

The two processors differ across nearly every major specification field. The AMD Ryzen AI 5 435 has 6 cores and 12 threads; the Intel Core 9 273PTE has 12 cores and 24 threads. Base clocks differ: AMD at 2.00 GHz versus Intel at 1.40 GHz. Boost clocks differ more significantly: AMD at 4.50 GHz versus Intel at 5.50 GHz. TDP is 28 W for AMD and 45 W for Intel. Sockets are entirely different: AMD Socket FP8 versus Intel Socket 1700. The AMD part uses Zen 5 architecture on a 4 nm TSMC process; the Intel part lists no architecture field, uses the Bartlett Lake codename on a 10 nm Intel process.

Cache configurations diverge in L2 and L3. Both have 80 KB of L1 per core, but AMD has 1 MB of L2 per core while Intel has 2 MB per core. L3 cache is 4 MB for AMD versus 36 MB shared for Intel. Memory support differs: AMD supports DDR5 and LPDDR5X, Intel supports DDR4 and DDR5. Both have dual-channel memory buses with identical 89.6 GB/s bandwidth. PCIe lanes differ: AMD offers Gen 4 with 14 lanes, Intel offers Gen 5 with 16 lanes. Integrated graphics differ: Radeon 840M for AMD, UHD Graphics 730 for Intel. Market segment differs: mobile for AMD, desktop for Intel. The Intel part has a launch MSRP of $549; the AMD part has no recorded launch MSRP. Release dates differ by about two months, with AMD in January 2026 and Intel in March 2026.

The Verdict

The recorded benchmark data paints a clear picture: the Intel Core 9 273PTE is the faster processor in the vast majority of workloads, and often by substantial margins. Its 12-core, 24-thread configuration with 36 MB of L3 cache delivers multi-core results that are roughly 44.6% ahead of the AMD Ryzen AI 5 435 in Cinebench R23, and the gap extends to 59.2% in the PassMark prime number test. For users who need maximum thread throughput, heavy integer or floating-point math, or large data compression workloads, the Intel part is the clear choice from the data.

The AMD Ryzen AI 5 435 does hold a measurable single-thread advantage in PassMark, scoring 8.8% higher than Intel, and it also leads by 1.5% in extended instructions. Those wins are real but narrow, and they do not offset the Intel part's advantages in the other 12 benchmarks. The AMD chip also operates at a much lower TDP of 28 W versus 45 W, which makes it more suitable for power-constrained mobile environments, and its Radeon 840M integrated graphics may be preferable for some use cases over Intel's UHD Graphics 730.

The database places the Intel part at the 82nd percentile of all CPUs and the AMD part at the 80th percentile, a modest overall ranking gap that understates the per-workload differences. The Intel part's average score of 31143 is roughly 10.7% higher than the AMD part's 28128. For desktop users who prioritize raw compute performance and have no constraints on power or socket choice, the Intel Core 9 273PTE is the stronger option based on the recorded measurements. For mobile users who value lower power draw and competitive single-thread performance, the AMD Ryzen AI 5 435 offers a more balanced profile, but it will not match the Intel part in multi-threaded or cache-heavy applications.
