AMD Ryzen 3 7335U vs Intel Core Ultra 5 134U Comparison

The Verdict

The benchmark data splits these two mobile processors into distinct personalities, and the choice depends entirely on workload priorities. The Intel Core Ultra 5 134U wins 10 of the 17 recorded head-to-head tests, while the AMD Ryzen 3 7335U takes 7. However, the magnitude of those wins matters more than the count. The AMD chip's victories in Cinebench R23 multi-core (10,703 vs 5,572, a 47.9% advantage) and PassMark data compression (146,309 vs 124,771, a 14.7% edge) are substantial, whereas many of Intel's wins are narrow single-core margins. The Intel part claims single-core supremacy in every Cinebench generation tested, from a 45.4% lead in R15 single-core (221 vs 152) to a more modest 4.3% lead in R23 single-core (1,576 vs 1,511). The AMD Ryzen 3 7335U is the pick for sustained multi-threaded rendering and data-heavy tasks, while the Intel Core Ultra 5 134U suits workloads that favor integer math, floating-point operations, and prime-number calculations. Both chips sit at the 70th percentile among all CPUs in the database, yet their average benchmark scores differ: the AMD part averages 16,827 versus Intel's 15,910, a gap of roughly 5.5%. Buyers seeking a balanced mobile processor with strong single-thread performance should lean toward Intel; those prioritizing multi-core throughput should favor AMD.

Architecture Differences

The two processors come from fundamentally different design philosophies. The Intel Core Ultra 5 134U uses Meteor Lake architecture on Intel's 7 nm process, while the AMD Ryzen 3 7335U employs Zen 3+ architecture on TSMC's 6 nm node. Intel's chip packs 12 cores and 14 threads, a hybrid arrangement that explains its higher core count but also its lower 9 W TDP. AMD counters with 4 cores and 8 threads, yet draws 28 W, a threefold power envelope difference that allows the smaller core count to run at higher sustained clocks. The base clock comparison is stark: Intel starts at 700 MHz while AMD begins at 3.00 GHz, though Intel's boost reaches 4.40 GHz versus AMD's 4.30 GHz. Cache hierarchies differ significantly: Intel allocates 112 KB L1 and 2 MB L2 per core with a 12 MB shared L3, while AMD uses 64 KB L1 and 512 KB L2 per core with only 8 MB shared L3. The AMD die measures 208 mm², while Intel's die size is not recorded. Memory support shows DDR5 on both, but AMD lists a specific 76.8 GB/s bandwidth figure and supports ECC memory, which Intel does not. PCIe lanes favor AMD at 20 Gen 4 lanes versus Intel's 8 Gen 4 lanes. Integrated graphics also differ: Intel pairs with Arc Xe-LPG 64EU, AMD with Radeon 660M. The AMD part launched earlier, on 2023-01-03, while Intel arrived on 2023-12-13. Intel lists a launch MSRP of $332, while AMD has no recorded launch MSRP.

Head-to-Head Benchmarks

The Cinebench results reveal a fascinating split. In R15 multi-core, AMD wins decisively: 1,078 versus 894, a 17.1% margin. Yet in R20 multi-core, Intel flips the result with 4,725 versus 4,495, a 5.1% lead. Then R23 multi-core swings violently back to AMD: 10,703 versus 5,572, a 47.9% blowout. This inconsistency suggests the two chips scale very differently across benchmark generations, possibly due to thermal or power management behavior. Single-core results are consistently Intel-favored: R15 shows 221 versus 152 (45.4% ahead), R20 shows 666 versus 634 (5% ahead), and R23 shows 1,576 versus 1,511 (4.3% ahead). PassMark tests paint a mixed picture. AMD wins data compression (146,309 vs 124,771, 14.7% ahead), data encryption (9,335 vs 8,077, 13.5% ahead), extended instructions (10,314 vs 7,002, 32.1% ahead), multithread (12,592 vs 12,464, 1% ahead), and random string sorting (15,361 vs 13,702, 10.8% ahead). Intel wins find prime numbers (56 vs 36, 55.6% ahead), floating-point math (32,425 vs 24,298, 33.4% ahead), integer math (51,306 vs 42,493, 20.7% ahead), physics (883 vs 647, 36.5% ahead), and single-thread (3,063 vs 3,053, a razor-thin 0.3% ahead). The closest contest is PassMark multithread, where AMD's 1% margin (12,592 vs 12,464) could easily fall within run-to-run variance. The largest single delta is the 47.9% R23 multi-core gap, followed by the 45.4% R15 single-core gap in Intel's favor.

FAQ

Q: Which processor has better single-core performance?

A: The Intel Core Ultra 5 134U wins every single-core benchmark recorded. It leads by 45.4% in Cinebench R15 single-core (221 vs 152), 5% in R20 single-core (666 vs 634), 4.3% in R23 single-core (1,576 vs 1,511), and 0.3% in PassMark single-thread (3,063 vs 3,053).

Q: Is the AMD Ryzen 3 7335U faster in multi-core workloads?

A: Not consistently. AMD wins Cinebench R15 multi-core by 17.1% (1,078 vs 894) and R23 multi-core by 47.9% (10,703 vs 5,572), but Intel wins R20 multi-core by 5.1% (4,725 vs 4,495) and trails by only 1% in PassMark multithread (12,464 vs 12,592).

Q: How do their power requirements compare?

A: The Intel Core Ultra 5 134U has a 9 W TDP, while the AMD Ryzen 3 7335U has a 28 W TDP. This means AMD draws more than three times the thermal design power, which likely explains its higher sustained multi-core performance despite having fewer cores.

Q: Which chip has more cores and threads?

A: The Intel Core Ultra 5 134U has 12 cores and 14 threads. The AMD Ryzen 3 7335U has 4 cores and 8 threads. Intel also offers larger caches: 12 MB shared L3 versus AMD's 8 MB, and 2 MB L2 per core versus AMD's 512 KB per core.

Q: Do both processors support DDR5 memory?

A: Yes, both list DDR5 support with dual-channel memory buses. However, AMD specifies a memory bandwidth of 76.8 GB/s and supports ECC memory, while Intel does not record ECC support or a specific bandwidth figure in the database.

Q: What are the closest rivals for each chip according to the database?

A: The Intel Core Ultra 5 134U sits near the AMD Ryzen 5 40 (0.2% higher average score), AMD EPYC 9334 (0.2% lower), AMD EPYC 75F3 (0.3% higher), and AMD EPYC 9354P (0.5% higher). The AMD Ryzen 3 7335U sits near the Intel Core i3-12100E (0.2% lower), Intel Core i5-1235U (0.3% higher), Intel Core Ultra 5 115U (0.4% higher), and AMD Ryzen 5 7235HS (0.4% lower).

Where Each One Wins

The Intel Core Ultra 5 134U dominates workloads involving mathematical computation. Its 55.6% lead in PassMark find prime numbers (56 vs 36) and 33.4% lead in floating-point math (32,425 vs 24,298) make it the stronger choice for scientific calculations, simulations, and any task that stresses FPU pipelines. The 20.7% integer math advantage (51,306 vs 42,493) extends this to general arithmetic-heavy applications. The physics test shows a 36.5% lead (883 vs 647), suggesting better performance in physics simulation workloads. Single-thread responsiveness is consistently better on Intel, with every Cinebench single-core test going its way, which translates to snappier everyday application performance. The 9 W TDP also means the Intel chip fits into thinner, cooler, and more power-efficient designs, making it the sensible option for ultraportable laptops where battery life and thermals take priority.

The AMD Ryzen 3 7335U wins where parallel throughput and data manipulation matter. The 47.9% Cinebench R23 multi-core advantage (10,703 vs 5,572) is the largest margin in the entire comparison and signals strong sustained all-core performance for video rendering, 3D modeling, and content creation. The 14.7% data compression lead (146,309 vs 124,771) and 10.8% random string sorting lead (15,361 vs 13,702) point to superior performance in archiving, database operations, and text processing. The 32.1% extended instructions advantage (10,314 vs 7,002) suggests better support for modern SIMD workloads. The 13.5% encryption lead (9,335 vs 8,077) favors tasks involving cryptography, secure connections, and data protection. The 28 W TDP indicates the AMD chip is designed for systems with more robust cooling, typically larger laptops or those with dedicated thermal solutions, where the extra power draw is an acceptable trade-off for multi-threaded muscle. The 20 PCIe Gen 4 lanes versus Intel's 8 also make AMD the better fit for systems with multiple high-speed storage devices or external GPUs.
