AMD Ryzen 7 9850X3D vs Intel Core Ultra 5 235T Comparison

Head-to-Head Benchmarks

The recorded data shows a clear split between these two processors. The AMD Ryzen 7 9850X3D takes 10 of the 15 head-to-head benchmark comparisons, while the Intel Core Ultra 5 235T wins 5. The margin of victory, however, tells a more interesting story than the raw win count.

Starting with the biggest AMD advantage, the PassMark physics test shows a 93.4% delta in favor of the Ryzen 7 9850X3D, with scores of 4171 versus 2157. This is the single largest gap in the entire comparison. Extended instructions also heavily favor AMD, with the Ryzen 7 9850X3D scoring 39272 against Intel's 23212, a 69.2% advantage. Data compression follows at 60.8% ahead, with AMD scoring 474501 versus 295100. Integer math shows a 46.2% lead for AMD at 123140 compared to 84244. Random string sorting favors AMD by 40.7%, with scores of 49764 versus 35377. Prime number finding shows AMD ahead by 36.8%, scoring 435 versus 318. The PassMark multithread test gives AMD a 33.6% lead at 41318 versus 30918. Finally, the Cinebench R15 multicore test shows AMD winning by 34.3%, scoring 3551 against Intel's 2644.

The Intel Core Ultra 5 235T's wins are concentrated in a few specific areas. The most dramatic is the Cinebench R23 single-core test, where Intel scores 3703 against AMD's 2228, a 39.8% advantage. This is the second-largest delta in the entire comparison. Cinebench R23 multicore also favors Intel, with a score of 26232 versus 22807, a 13.1% lead. Floating point math shows Intel ahead by 23%, scoring 106546 versus 81998. The Cinebench R15 single-core test gives Intel a smaller 8% edge at 373 versus 343. Data encryption is nearly even, with Intel winning by just 2.6%, scoring 23457 versus 22856.

The single-thread results in PassMark tell a different story than the Cinebench single-core results. The PassMark single-thread test shows AMD winning by 8.4%, with a score of 4704 versus 4339. This contrasts sharply with the Cinebench R23 single-core result, where Intel leads by 39.8%. The two suites clearly measure different aspects of single-thread performance, and the data shows AMD holding a moderate lead in the PassMark metric while Intel dominates the Cinebench metric.

The average benchmark score positions the AMD Ryzen 7 9850X3D at 58386, which places it in the 92nd percentile of all CPUs in the database.

The Verdict

The benchmark data indicates that the AMD Ryzen 7 9850X3D is the stronger overall performer, with a 51.4% higher average benchmark score and a 92nd percentile ranking versus Intel's 86th percentile. The AMD processor wins 10 of 15 comparisons, and many of those wins are by substantial margins. The physics test, extended instructions, data compression, and integer math results show AMD delivering between 46.2% and 93.4% higher scores. For workloads that depend on these areas, the choice is clear.

The Intel Core Ultra 5 235T, however, has specific strengths that should not be overlooked. Its Cinebench R23 single-core result of 3703 versus 2228 is a decisive 39.8% advantage, and its Cinebench R23 multicore score of 26232 versus 22807 shows a 13.1% lead in that particular workload. Floating point math also favors Intel by 23%. The data suggests that Intel's processor is competitive in rendering workloads as measured by Cinebench and in floating point operations, while AMD's processor dominates in compression, encryption-adjacent tasks like extended instructions, integer math, and physics simulations.

The data does not support a universal winner. The AMD Ryzen 7 9850X3D delivers higher scores across a broader range of tests, making it the more versatile choice based on the database measurements. The Intel Core Ultra 5 235T is the better option specifically for Cinebench-style rendering and floating point math, where its recorded scores are meaningfully higher.

Architecture Differences

The AMD Ryzen 7 9850X3D uses the Zen 5 architecture on the Granite Ridge codename, built on a 4 nm process at TSMC. The Intel Core Ultra 5 235T uses the Arrow Lake architecture on the Arrow Lake-S codename, built on a 3 nm process at TSMC. The transistor counts differ substantially: AMD's chip has 8,315 million transistors on a 70.6 mm² die, while Intel's chip has 17,800 million transistors on a 243 mm² die.

Core configuration is a major divergence. The AMD processor has 8 cores and 16 threads, while the Intel processor has 14 cores and 14 threads. The Intel part has more physical cores but no hyperthreading, resulting in fewer total threads. The AMD part relies on simultaneous multithreading to reach 16 threads from 8 cores.

Cache hierarchies also differ significantly. The AMD Ryzen 7 9850X3D has 80 KB of L1 per core, 1 MB of L2 per core, and 96 MB of shared L3 cache. The Intel Core Ultra 5 235T has 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3 cache. The AMD processor's L3 cache is 4 times larger, which likely contributes to its strong performance in data compression and extended instructions tests.

Clock speeds show AMD with a 4.70 GHz base clock and 5.60 GHz boost clock, while Intel runs at 2.20 GHz base and 5.00 GHz boost. Thermal design power differs as well, with AMD rated at 120 watts and Intel at 65 watts. The AMD processor uses the AMD Socket AM5, while Intel uses the Intel Socket 1851.

Memory support is DDR5 for both, with dual-channel buses. AMD lists memory bandwidth of 89.6 GB/s, while Intel lists 102.4 GB/s. AMD supports ECC memory; Intel does not. PCIe connectivity also differs: AMD provides Gen 5 with 24 lanes from the CPU, while Intel provides Gen 5 with 20 lanes from the CPU. The integrated graphics differ, with AMD using Radeon Graphics and Intel using Arc Xe-LPG Graphics 24EU. The AMD multiplier is unlocked, while the Intel multiplier is locked. AMD's launch MSRP is $499, and Intel's is $247.

Where Each One Wins

The AMD Ryzen 7 9850X3D wins in PassMark multithread, physics, integer math, extended instructions, data compression, random string sorting, find prime numbers, PassMark single-thread, and Cinebench R15 multicore. These results point to strengths in arithmetic-heavy workloads, compression tasks, physics calculations, and general multithreaded throughput. The 93.4% physics win and the 69.2% extended instructions win are the standout results for AMD. The 96 MB L3 cache and 16 threads likely play a role in these outcomes.

The Intel Core Ultra 5 235T wins in Cinebench R23 multicore, Cinebench R23 single-core, Cinebench R15 single-core, floating point math, and data encryption. The Cinebench R23 single-core result is particularly strong, with Intel scoring 3703 against AMD's 2228. The floating point math score of 106546 versus 81998 shows a clear Intel advantage in FP-heavy work. The Cinebench R23 multicore win at 26232 versus 22807 indicates Intel's 14 physical cores deliver in that specific rendering benchmark despite having fewer threads.

The split is clean: AMD dominates in integer-heavy and cache-sensitive workloads, while Intel leads in Cinebench rendering and floating point math. The PassMark single-thread result goes to AMD by 8.4%, which complicates the notion that Intel simply has the faster single-core architecture. The data shows Intel winning Cinebench single-core by a wide margin while losing PassMark single-thread by a moderate one, so conclusions about single-thread superiority depend on which benchmark is trusted.
