AMD Ryzen 7 PRO 5755GE vs Intel Core Ultra 9 285 Comparison

Where Each One Wins

The recorded benchmark data presents a complete sweep for the Intel Core Ultra 9 285. Across all 17 head-to-head comparisons, the Intel part claims the win, leaving the AMD Ryzen 7 PRO 5755GE with zero victories. This is not a close contest by any metric, but the magnitude of the Intel advantage varies significantly depending on the workload type.

The most lopsided results appear in prime number finding and physics simulations. In the PassMark find prime numbers test, the Intel Core Ultra 9 285 scores 459 against just 50 for the AMD chip, a delta of 89.1 percent in Intel's favor. Physics computation shows a similar pattern, with Intel at 3598 versus AMD's 841, a 76.6 percent gap. These workloads benefit from raw instruction throughput and high core counts, both of which favor the Intel design.

Floating point math presents another dominant Intel win. The Core Ultra 9 285 delivers 194988 in the PassMark floating point test, while the Ryzen 7 PRO 5755GE manages 46589, a 76.1 percent deficit for AMD. Integer math tells a somewhat less severe story, with Intel leading 164869 to 84004, a 49 percent gap. This narrower margin indicates that the AMD processor's integer execution units are comparatively more competitive relative to its floating point performance.

Single-threaded workloads show the smallest Intel advantage. In PassMark single thread, Intel scores 4881 versus AMD's 3353, a 31.3 percent lead. The Cinebench single-core results show a wider gap, with Intel ahead by 63.8 percent in R15, 63.7 percent in R20, and 63.7 percent in R23. The discrepancy between PassMark and Cinebench single-thread results suggests that the AMD chip's Zen 3 architecture handles certain scalar workloads better than others, but it still trails clearly in every measured test.

The average benchmark scores reflect the overall picture. The Intel Core Ultra 9 285 holds an average benchmark score of 75488 and sits in the 95th percentile of all CPUs in the database. The AMD Ryzen 7 PRO 5755GE averages 29656 and places in the 81st percentile. The Intel processor's nearest rivals include server-class AMD EPYC parts and high-end Ryzen 7 PRO chips, while the AMD Ryzen 7 PRO 5755GE competes with mainstream desktop and mobile processors.

Architecture Differences

The two processors come from fundamentally different design generations and process technologies. The AMD Ryzen 7 PRO 5755GE uses the Zen 3 architecture, codenamed Cezanne, built on a 7 nm process at TSMC. It packs 8 cores and 16 threads, a configuration that relies on simultaneous multithreading to double its logical thread count. The Intel Core Ultra 9 285 uses the Arrow Lake architecture, codenamed Arrow Lake-S, fabricated on a 3 nm process, also at TSMC. It provides 24 cores and 24 threads, with no hyperthreading to expand the thread count.

Transistor counts differ substantially. The AMD chip contains 10,700 million transistors on a 180 mm² die. The Intel processor carries 17,800 million transistors across a 243 mm² die. The newer 3 nm process gives Intel a density advantage, but the larger core count and bigger cache hierarchy account for the increased transistor budget.

Cache configurations diverge sharply. Each AMD core gets 64 KB of L1 and 512 KB of L2, with a shared 16 MB L3 pool. Each Intel core receives 192 KB of L1 and 3 MB of L2, with a shared 36 MB L3 cache. The Intel processor's per-core L2 allocation is six times larger than AMD's, which helps feed its higher clock speeds and wider execution resources. The 36 MB shared L3 also gives Intel more capacity for working sets in data-heavy applications.

Clock behavior shows Intel's aggressive boosting strategy. The AMD part runs at a 3.20 GHz base clock with a 4.60 GHz boost. The Intel chip starts at a lower 2.50 GHz base but boosts to 5.60 GHz, a full gigahertz higher than AMD's ceiling. This boost advantage underpins Intel's single-threaded wins in Cinebench and PassMark.

Memory and platform support highlight the generational divide. AMD uses DDR4 memory with dual-channel access and a measured bandwidth of 51.2 GB/s. Intel moves to DDR5 with dual-channel access and a bandwidth rating of 102.4 GB/s, exactly double AMD's figure. Intel also supports ECC memory, which the AMD chip does not. PCIe connectivity differs as well, with AMD limited to Gen 3 and 16 lanes from the CPU, while Intel provides Gen 5 with 20 lanes.

Integrated graphics take different approaches. The AMD Ryzen 7 PRO 5755GE includes Radeon Vega 8 graphics, while the Intel Core Ultra 9 285 uses Arc Xe-LPG Graphics with 64 execution units. Both processors target desktop sockets, AMD on Socket AM4 and Intel on Socket 1851. Neither chip has an unlocked multiplier. The Intel part lists a launch MSRP of $579.

Head-to-Head Benchmarks

The Cinebench suite shows Intel's dominance across every iteration. In Cinebench R15 multicore, Intel scores 4933 against AMD's 1789, a 63.7 percent lead. The single-core R15 test gives Intel 696 versus AMD's 252, a 63.8 percent margin. Moving to R20, Intel's multicore result of 20556 dwarfs AMD's 7458, again by 63.7 percent. The R20 single-core test shows Intel at 2901 and AMD at 1052, a 63.7 percent gap. Cinebench R23 continues the pattern: Intel's 48945 multicore score beats AMD's 17759 by 63.7 percent, and Intel's 6909 single-core score beats AMD's 2507 by the same margin.

The PassMark suite reveals where the gap widens and narrows. Data compression sees Intel at 602121 and AMD at 252937, a 58 percent difference. Encryption shows Intel at 46949 and AMD at 16937, a 63.9 percent gap. Extended instructions favor Intel 45357 to 17029, a 62.5 percent margin. Prime number finding is the most extreme case, with Intel at 459 and AMD at 50, an 89.1 percent difference. Floating point math shows Intel at 194988 versus AMD's 46589, a 76.1 percent gap. Integer math is the closest PassMark test, with Intel at 164869 and AMD at 84004, a 49 percent margin. Multithread performance gives Intel 56602 against AMD's 20870, a 63.1 percent lead. Physics favors Intel 3598 to 841, a 76.6 percent gap. Random string sorting shows Intel at 73651 and AMD at 27373, a 62.8 percent difference. Single-thread performance gives Intel 4881 and AMD 3353, the smallest overall gap at 31.3 percent.

The data indicates that the Intel processor's advantage is consistent but not uniform. Workloads that stress floating point, physics, and prime number calculations amplify Intel's lead beyond 75 percent. Integer math and single-threaded tests keep the gap closer to the 30 to 50 percent range. The AMD chip's competitive zones are relative, not absolute: it comes closest to Intel in single-threaded PassMark performance and integer math, but it still loses decisively in every recorded measurement.

The Verdict

The benchmark data directs a clear choice based on workload demands. The Intel Core Ultra 9 285 wins every head-to-head test in the database, with an average benchmark score of 75488 that places it in the 95th percentile of all CPUs. Its nearest rivals are AMD EPYC server processors and high-end Ryzen 7 PRO parts, which confirms its position at the top of the desktop hierarchy. Any workload that prioritizes multi-threaded throughput, floating point math, or high single-core performance will benefit from this processor.

The AMD Ryzen 7 PRO 5755GE, with an average score of 29656 and an 81st percentile ranking, competes in a different performance class. Its nearest rivals include the AMD Ryzen 5 9600X, Ryzen AI 7 345, Ryzen 7 3800X, and Ryzen 7 7840H, all of which sit within roughly one percent of its average score. This places the AMD chip in mainstream territory rather than flagship territory.

The launch MSRP for the Intel Core Ultra 9 285 is $579. The AMD part has no recorded launch MSRP in the database. Buyers choosing between these two processors should weigh the Intel chip's complete benchmark superiority against its higher platform requirements, including DDR5 memory support and the newer Socket 1851. The AMD processor offers a lower-power design at 35 watts TDP compared to Intel's 65 watts, which may matter for compact builds or thermally constrained systems. For raw performance across every measured metric, the Intel Core Ultra 9 285 is the only choice the data supports.
