AMD Ryzen 5 9600X vs Intel Core Ultra 5 135H Comparison

The AMD Ryzen 5 9600X and Intel Core Ultra 5 135H occupy different market segments: the former is a desktop processor built for raw performance, while the latter is a mobile chip designed for efficiency. The recorded benchmark data, however, shows a decisive performance gap. The AMD wins all 15 head-to-head comparisons, with an average benchmark score of 29713 against 29093 for the Intel. Both processors sit at the 81st percentile among all CPUs, but the AMD's per-core and multi-thread results are consistently higher across every test.

Head-to-Head Benchmarks

The largest margin of victory for the AMD Ryzen 5 9600X comes in the PassMark find prime numbers test, where it scores 233 against the Intel's 89, a delta of 161.8%. This is a dramatic lead in a workload that stresses integer arithmetic and branch prediction. The extended instructions test shows a similar pattern: the AMD scores 28023 versus 15028, a 86.5% advantage. These two results highlight the AMD's superior instruction-level efficiency and per-core throughput.

In multi-threaded rendering, the AMD also dominates. In Cinebench R23 multi-core, the AMD scores 17528.5 against the Intel's 11875.5, a 47.6% lead. The Cinebench R15 multi-core test shows a 56.6% advantage (2691 vs 1718). Even in single-thread tests, where the Intel's higher core count offers no benefit, the AMD leads: Cinebench R23 single-core scores 2183.5 versus 1700 (28.4% ahead), and Cinebench R15 single-core scores 342 versus 244 (40.2% ahead). The PassMark single-thread test confirms this, with the AMD at 4570 and the Intel at 3521, a 29.8% gap.

The AMD also wins in more specialized workloads. PassMark data compression shows 341021 versus 251651, a 35.5% lead. Integer math scores 89918 versus 73509 (22.3% ahead), and floating point math scores 60081 versus 54867 (9.5% ahead). The smallest margin is in data encryption, where the AMD leads by 10.7% (16638 vs 15026). Even in physics simulation, the AMD scores 2012 against 1482, a 35.8% advantage. The multithread test shows 30027 versus 22422, a 33.9% lead, and random string sorting shows 35946 versus 28980, a 24% lead.

Across all 15 recorded head-to-head tests, the AMD Ryzen 5 9600X wins every single one. The Intel Core Ultra 5 135H does not claim a single victory, despite having more cores and threads. The data indicates that the AMD's architecture delivers higher performance per core and better overall throughput in every measured workload.

Where Each One Wins

Based on the recorded benchmark data, the Intel Core Ultra 5 135H does not win any of the 15 head-to-head comparisons. The AMD Ryzen 5 9600X leads in every category, from single-thread to multi-thread, from integer math to data compression. This is a clean sweep.

However, the Intel's profile suggests a different use case. It is a mobile processor with a TDP of 28 watts, compared to the AMD's 65 watts. It is designed for laptops and compact systems where power efficiency is critical. The AMD, on the other hand, is a desktop part with a higher power envelope and an unlocked multiplier, indicating it is intended for performance-oriented builds. The benchmark scores reflect this: the AMD's higher clock speeds (5.40 GHz boost versus 4.60 GHz) and larger L3 cache (32 MB versus 18 MB) contribute to its dominance.

For users who prioritize raw performance, the AMD is the clear choice. For those who need a low-power mobile solution, the Intel may be considered, but the data shows that it trails the AMD in every measured metric. The Intel's higher core count (14 vs 6) does not translate into better scores, as the AMD's per-core efficiency and higher boost clock compensate for the core deficit.

Architecture Differences

The two processors are built on fundamentally different architectures. The AMD Ryzen 5 9600X uses the Zen 5 architecture, codenamed Granite Ridge, fabricated on a 4 nm process at TSMC. It has 6 cores and 12 threads, with a base clock of 3.90 GHz and a boost clock of 5.40 GHz. The Intel Core Ultra 5 135H uses the Meteor Lake architecture, fabricated on a 7 nm process at Intel. It has 14 cores and 18 threads, with a base clock of 3.60 GHz and a boost clock of 4.60 GHz.

Cache configurations differ significantly. The AMD has 80 KB of L1 cache per core, 1 MB of L2 per core, and 32 MB of shared L3 cache. The Intel has 112 KB of L1 per core, 2 MB of L2 per core, and 18 MB of shared L3 cache. The AMD's larger L3 cache is likely a factor in its superior performance in data compression and extended instruction workloads.

Memory support is similar: both support DDR5 and use a dual-channel memory bus with a bandwidth of 89.6 GB/s. However, the AMD supports ECC memory, while the Intel does not. The AMD also offers more PCIe lanes: Gen 5 with 24 lanes (CPU only) versus the Intel's Gen 5 with 8 lanes. The integrated graphics differ as well: the AMD has Radeon Graphics, while the Intel has Arc Xe-LPG 96EU.

The AMD is a desktop processor on the AM5 socket, while the Intel is a mobile processor on the BGA 2049 socket. The AMD has an unlocked multiplier, allowing overclocking, while the Intel is locked. The AMD was released on August 7, 2024, with a launch MSRP of $279. The Intel was released on December 13, 2023, with a launch MSRP of $342. The AMD's die size is 70.6 mm² with 8,315 million transistors, while the Intel's die size and transistor count are not recorded.

The Verdict

The recorded data is unambiguous: the AMD Ryzen 5 9600X outperforms the Intel Core Ultra 5 135H in every benchmark test. The AMD leads by margins ranging from 9.5% in floating point math to 161.8% in find prime numbers. Its higher boost clock, larger L3 cache, and more efficient Zen 5 architecture deliver superior results across single-thread and multi-thread workloads.

The Intel Core Ultra 5 135H, despite having more cores and threads, cannot match the AMD's per-core performance. Its lower TDP and mobile form factor make it suitable for laptops and power-constrained systems, but the benchmark scores show that it sacrifices performance for efficiency. The AMD's unlocked multiplier and desktop socket also make it a better choice for enthusiasts who want to overclock.

For users building a desktop system and prioritizing raw performance, the AMD Ryzen 5 9600X is the clear pick. For those who need a low-power mobile processor, the Intel may be considered, but the data shows that it trails the AMD in every measured metric. The AMD's average benchmark score of 29713 places it just 0.2% above the AMD Ryzen 7 PRO 5755GE, while the Intel's 29093 is 0.1% below the AMD Ryzen 7 5800X. Both sit at the 81st percentile, but the AMD's consistent wins in head-to-head tests make it the superior performer.
