AMD Ryzen 7 9850X3D vs Intel Core Ultra 9 285H Comparison

Head-to-Head Benchmarks

The recorded benchmark data shows a decisive overall advantage for the AMD Ryzen 7 9850X3D, which claims 13 wins out of 15 head-to-head tests. The Intel Core Ultra 9 285H secures only two victories, but those wins are significant in their respective categories.

The largest margin of victory belongs to the AMD part in the Passmark extended instructions test, where it scores 39,272 versus Intel's 26,794, a delta of 46.6%. This indicates a substantial advantage in workloads that utilize specialized instruction sets. The data compression test shows a similarly commanding lead for AMD, scoring 474,501 against 335,859, a 41.3% delta. Integer math performance also heavily favors the Ryzen 7 9850X3D, with a score of 123,140 compared to 85,922, a 43.3% difference.

The second Intel win comes in floating point math, where the Core Ultra 9 285H posts 109,190 versus AMD's 81,998, which is a 24.9% advantage for Intel. This is a notable reversal, suggesting the Intel architecture handles floating point workloads with greater efficiency despite losing most other computational tests.

In the Cinebench suite, AMD leads across the board. The R23 multicore test shows a score of 22,807 for AMD against 20,781.5 for Intel, a 9.7% delta. The R23 singlecore test is closer, with AMD at 2,228 versus 2,129.5, a 4.6% difference. The R15 multicore test shows an 11.8% lead for AMD (3,551 versus 3,177.5), while R15 singlecore shows a 9.6% advantage (343 versus 313). The single-thread Passmark test also favors AMD, with 4,704 versus 4,415, a 6.5% delta.

The multithread Passmark result shows AMD at 41,318 versus Intel's 34,171, a 20.9% lead. The physics test has the largest percentage delta of any test, with AMD scoring 4,171 versus 2,513, a 66% advantage. Random string sorting shows AMD ahead by 21.6% (49,764 versus 40,931). The find prime numbers test gives AMD a 31.8% edge (435 versus 330).

The data encryption test is the other Intel win. Intel scores 26,140 versus AMD's 22,856, a 12.6% delta in favor of Intel. This suggests that encryption workloads, which often rely on specific AES instruction paths, are a relative strength for the Core Ultra 9 285H.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 7 9850X3D is a desktop part built on the Zen 5 architecture, codenamed Granite Ridge, using a 4 nm process from TSMC. It has 8 cores and 16 threads. The Intel Core Ultra 9 285H is a mobile processor based on the Arrow Lake architecture, specifically Arrow Lake-H, using a 3 nm process also from TSMC. It has 16 cores but only 16 threads, indicating that Intel is not using simultaneous multithreading in this design.

Cache configurations differ sharply. AMD provides 80 KB of L1 cache per core, 1 MB of L2 per core, and a large 96 MB shared L3 cache. Intel provides 192 KB of L1 per core, 3 MB of L2 per core, but only 24 MB of shared L3. The AMD L3 cache is four times larger, which is a critical factor for workloads that benefit from large data residency near the cores.

Clock speeds also differ. AMD lists a base clock of 4.70 GHz and a boost clock of 5.60 GHz. Intel lists a base clock of 2.90 GHz and a boost clock of 5.40 GHz. The AMD part has both a higher base and a higher boost clock.

Power characteristics are not directly comparable due to different market segments. The AMD part has a TDP of 120 watts and uses the AMD Socket AM5. The Intel part has a TDP of 45 watts and uses the Intel BGA 2049 socket, which is a mobile package. The AMD part has an unlocked multiplier, while the Intel multiplier is locked.

Both support DDR5 memory in dual-channel mode. AMD lists a memory bandwidth of 89.6 GB/s, while Intel lists 102.4 GB/s. Intel also supports LPDDR5X memory, which AMD does not list. Both support ECC memory. For PCIe, AMD provides Gen 5 with 24 lanes (CPU only), while Intel provides Gen 5 with 8 lanes (CPU only).

The integrated graphics differ. AMD includes Radeon Graphics, while Intel includes Arc Graphics 140T. The transistor count for AMD is listed as 8,315 million with a die size of 70.6 mm². No transistor count or die size is recorded for the Intel part.

Where Each One Wins

The AMD Ryzen 7 9850X3D wins in the majority of computational tests, particularly those that stress integer math, data compression, extended instructions, and prime number finding. Its 66% lead in the physics test is the single largest delta in the dataset. The multithread score advantage of 20.9% reflects the combination of high clock speeds and large L3 cache. The singlecore advantage of 6.5% in Passmark and 4.6% in Cinebench R23 shows that AMD also holds a lead in lightly threaded workloads.

The Intel Core Ultra 9 285H wins in exactly two categories: data encryption and floating point math. The encryption win is a 12.6% delta, and the floating point win is a 24.9% delta. These are specific, narrow strengths. The floating point result is particularly interesting because it shows Intel delivering a higher score despite having a lower boost clock and fewer threads than it has cores. The encryption result points to a possible advantage in AES-NI or similar instruction throughput.

For use-case analysis, the AMD part is the stronger choice for general compute, physics simulation, integer-heavy code, and any workload that can leverage a large L3 cache. The Intel part is the better option for floating point calculations and encryption-heavy tasks, such as certain scientific computing or secure data handling scenarios. The 45-watt TDP of the Intel part also suggests it is designed for a different power envelope, though the data does not include efficiency benchmarks.

The Verdict

The data clearly indicates that the AMD Ryzen 7 9850X3D is the stronger performer across the vast majority of tested workloads. Its wins in 13 of 15 head-to-head tests, including all Cinebench tests and most Passmark tests, establish it as the higher-performance part in this comparison. The average benchmark score of 58,386 versus 38,312 places the AMD part in the 92nd percentile of all CPUs, while the Intel part sits in the 86th percentile.

The Intel Core Ultra 9 285H should be chosen only for scenarios where floating point math or data encryption is the dominant workload. Its 24.9% lead in floating point and 12.6% lead in encryption are the only areas where it outperforms the AMD part. For all other measured tasks, including singlecore, multicore, integer math, and data compression, the AMD Ryzen 7 9850X3D delivers higher scores.

The AMD part also offers a larger L3 cache (96 MB versus 24 MB), a higher boost clock (5.60 GHz versus 5.40 GHz), and an unlocked multiplier. The Intel part offers a lower TDP (45 watts versus 120 watts) and a smaller PCIe lane count (8 versus 24), but the benchmark data does not show these translating into performance wins outside of the two noted categories.
