AMD Ryzen AI 5 PRO 435G vs Intel Core Ultra 5 338H Comparison

Head-to-Head Benchmarks

The benchmark data for the AMD Ryzen AI 5 PRO 435G and Intel Core Ultra 5 338H shows a clear sweep: the Intel Core Ultra 5 338H wins all 11 recorded head-to-head comparisons. The average benchmark score for the AMD part is 40718, while the Intel part averages 33989. However, that aggregate figure masks the per-test reality, where Intel consistently outperforms AMD in every measured workload.

The largest margin appears in the prime number search test. AMD scores 55, while Intel reaches 304, producing a delta of -81.9%. This is a substantial gap that indicates a significant difference in integer-heavy algorithmic workloads. The floating point math test shows a similar story: AMD records 43494 versus Intel's 84067, a -48.3% difference. This means Intel delivers nearly double the floating point throughput, which matters for scientific and simulation tasks.

Data encryption also favors Intel heavily. AMD scores 12111, while Intel scores 21367, a -43.3% delta. The physics test follows the same pattern: AMD at 999, Intel at 2697, a -63% difference. This physics score may reflect the combined effects of thread scheduling and instruction efficiency.

The multithread test shows Intel ahead by -29.4%, with scores of 20285 for AMD and 28717 for Intel. Extended instructions show a -21.8% delta (18697 versus 23906), and random string sorting shows -19.6% (27407 versus 34082). These are moderate but consistent advantages.

The closest margins appear in integer math and single-thread tests. Integer math shows AMD at 63707 and Intel at 64934, a -1.9% delta. Single-thread performance shows AMD at 3829 and Intel at 4180, a -8.4% delta. These narrow gaps suggest that in lightly threaded integer workloads, the two processors are nearly comparable, with Intel holding only a small edge.

Data compression shows AMD at 253484 and Intel at 276539, a -8.3% delta. This is another moderate advantage for Intel, but the absolute scores are high for both, indicating both processors handle compression workloads well.

The aggregate picture is unambiguous. Intel wins every head-to-head test, with margins ranging from 1.9% to 81.9%. The AMD processor does not win a single comparison in the recorded database, despite having a higher average benchmark score. This paradox is explained by the fact that the average score may include different test sets or weighting, but the direct pairwise comparisons all favor Intel.

Architecture Differences

The two processors come from different design philosophies and manufacturing backgrounds. The AMD Ryzen AI 5 PRO 435G uses the Gorgon Point codename, part of the Ryzen AI PRO 400 generation based on Zen 5 and Zen 5c cores. It is built on a 4 nm process at TSMC. The Intel Core Ultra 5 338H uses the Panther Lake architecture, part of the Ultra 5 generation (Panther Lake-H), manufactured on a 3 nm process at Intel's own foundry.

Core counts differ significantly. The AMD processor has 6 cores and 12 threads. The Intel processor has 12 cores and 12 threads. This means Intel has double the physical cores but no hyperthreading, while AMD uses simultaneous multithreading to reach 12 threads from 6 cores. The core count advantage for Intel likely drives much of the multithread performance gap.

Cache hierarchies also differ. AMD provides 80 KB of L1 cache per core, 1 MB of L2 per core, and 4 MB of L3. Intel provides 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The Intel L3 cache is 4.5 times larger, which can improve hit rates for working sets that exceed the smaller AMD L3.

Clock speeds favor Intel at the top end. AMD has a base clock of 2.00 GHz and boost of 4.50 GHz. Intel has a base of 1.90 GHz and boost of 4.70 GHz. The boost advantage of 0.20 GHz for Intel contributes to its single-thread lead, though the base clock is slightly lower.

Memory support and bandwidth differ. AMD supports DDR5 with dual-channel memory and 89.6 GB/s bandwidth. Intel supports LPDDR5X with dual-channel memory and 136.5 GB/s bandwidth. The Intel memory bandwidth is 52.6% higher, which may benefit memory-intensive workloads. AMD supports ECC memory, while Intel does not.

PCIe capabilities differ. AMD uses Gen 4 with 10 lanes (CPU only). Intel uses Gen 5 with 4 lanes (CPU only). The AMD configuration offers more lanes at a slower standard, while Intel offers fewer lanes at a faster standard.

Integrated graphics differ. AMD uses Radeon 840M, while Intel uses Arc B370. The database does not include graphics benchmarks, so performance comparisons are not available from this data.

The market segments differ. AMD is classified as a desktop processor on the AMD Socket AM5. Intel is classified as a mobile processor on the Intel BGA 2540 socket. This affects system integration: AMD targets desktop builds, while Intel targets laptop or small-form-factor mobile designs. The TDP reflects this: AMD has a 65 W TDP, while Intel has a 25 W TDP. The lower Intel TDP is typical for mobile parts, though the performance data still favors Intel in all tests.

Where Each One Wins

Based on the recorded head-to-head results, the AMD Ryzen AI 5 PRO 435G does not win any benchmark comparison. The Intel Core Ultra 5 338H wins all 11 tests. Therefore, the use-case split must be inferred from the margins rather than from any AMD victory.

For workloads where the margin is small, the AMD processor may be considered competitive. Integer math shows only a 1.9% gap in favor of Intel. This suggests that integer-heavy applications, such as database operations or general business logic, will see nearly identical performance from either chip. The single-thread gap of 8.4% is also relatively modest, meaning lightly threaded integer tasks will not show a dramatic difference.

For workloads where the margin is large, Intel is the clear choice. Prime number search shows an 81.9% gap. Floating point math shows a 48.3% gap. Physics simulation shows a 63% gap. Data encryption shows a 43.3% gap. These workloads include scientific computing, financial modeling, cryptography, and any application that relies heavily on mathematical computation.

Multithread performance favors Intel by 29.4%. This means parallel workloads, such as video rendering, compilation, or data processing across many threads, will complete faster on the Intel processor. The 12 physical cores provide a structural advantage over the 6-core AMD part, even with AMD's SMT.

Data compression and extended instructions show moderate gaps of 8.3% and 21.8% respectively. Random string sorting shows a 19.6% gap. These tasks are common in data engineering and text processing, where Intel holds a consistent but not overwhelming edge.

The market segment difference matters. The AMD desktop part with a 65 W TDP may fit in power-unconstrained desktop systems, while the Intel mobile part with a 25 W TDP suits thermally constrained laptops. However, the performance data shows that the lower-TDP Intel part still outperforms the higher-TDP AMD part in every measured metric.

The Verdict

The data clearly favors the Intel Core Ultra 5 338H across every recorded benchmark. With 11 wins out of 11 head-to-head comparisons, the Intel processor demonstrates consistent superiority in single-thread, multithread, math, encryption, compression, and physics workloads. The margins range from small (1.9% in integer math) to very large (81.9% in prime number search), but no test shows the AMD processor ahead.

The Intel processor achieves this with a lower TDP of 25 W compared to the AMD part's 65 W. It also uses a newer 3 nm process versus the AMD part's 4 nm process. The core count advantage (12 versus 6) and the larger L3 cache (18 MB versus 4 MB) are structural factors that likely explain the consistent wins.

The AMD processor does have the higher average benchmark score (40718 versus 33989) and the higher percentile rank (87 versus 84). However, the direct pairwise comparisons contradict this aggregate figure. The nearest rivals for the AMD processor include the Intel Xeon 6357P, Intel Core 5 223PE, Intel Core 7 253PE, and Intel Core Ultra X7 368H, all with average scores within 0.5% of the AMD part. The nearest rivals for the Intel processor include the Intel Core Ultra 7 165H, Intel Core i7-12800HX, Intel Xeon 6353P, and AMD EPYC 4244P, with deltas ranging from -0.7% to 0.4%.

For a desktop build where power consumption is not the primary constraint, the AMD processor offers a higher average benchmark score and ECC memory support. For any workload where the specific benchmark tests matter, the Intel processor wins. The database provides no scenario where the AMD processor outperforms the Intel part in a direct comparison.

The choice depends on priorities. If ECC memory support and a higher aggregate score are the deciding factors, the AMD Ryzen AI 5 PRO 435G is the selection. If per-test performance, lower power draw, and mobile integration matter, the Intel Core Ultra 5 338H is the selection. The recorded data favors Intel in every direct benchmark.
