AMD Ryzen 5 PRO 8500GE vs Intel Core Ultra 9 285 Comparison

The Verdict

The benchmark data presents a decisive performance hierarchy between these two processors. The Intel Core Ultra 9 285 wins all 17 recorded head-to-head comparisons, with no benchmark victories recorded for the AMD Ryzen 5 PRO 8500GE. The Intel part sits at the 95th percentile of all CPUs in the database, while the AMD part sits at the 80th percentile. The average benchmark score for the Intel processor is 75,488, compared to 28,054 for the AMD processor.

The Intel Core Ultra 9 285 belongs to a performance class defined by its nearest rivals, which include the AMD EPYC 8224P (average score 75,582, delta -0.1%), the AMD EPYC 4545P (average score 75,373, delta 0.2%), the AMD Ryzen 7 PRO 9755X3D (average score 75,716, delta -0.3%), and the AMD Ryzen 7 PRO 9755 (average score 75,738, delta -0.3%). These delta values indicate that the Intel processor is statistically indistinguishable from those server and workstation parts in aggregate performance.

The AMD Ryzen 5 PRO 8500GE, by contrast, aligns with a more modest performance tier. Its nearest rivals include the Intel Core i5-14500T (average score 28,065, delta 0%), the AMD Ryzen 5 PRO 5655G (average score 28,032, delta 0.1%), the Intel Core i9-12900H (average score 28,003, delta 0.2%), and the AMD Ryzen AI 5 435 (average score 28,128, delta -0.3%). The AMD part is therefore competitive with those mainstream and mobile processors, but it is not in the same performance category as the Intel Core Ultra 9 285.

The data indicates that the Intel Core Ultra 9 285 is the appropriate choice for workloads that demand maximum multi-threaded throughput, single-core responsiveness, and computational intensity across all measured categories. The AMD Ryzen 5 PRO 8500GE, with its 35 watt TDP and mobile market segment classification, is positioned for systems where power efficiency and compact integration take priority over raw performance. The choice between them depends entirely on whether the workload prioritizes absolute performance or energy-conscious operation.

Architecture Differences

The two processors diverge fundamentally in architecture, manufacturing process, and design philosophy. The AMD Ryzen 5 PRO 8500GE uses the Zen 4 architecture with the Phoenix2 codename, manufactured on a 4 nm process at TSMC. It contains 20,900 million transistors on a 137 mm² die. The Intel Core Ultra 9 285 uses the Arrow Lake architecture with the Arrow Lake-S codename, manufactured on a 3 nm process, also at TSMC. It contains 17,800 million transistors on a larger 243 mm² die. The smaller transistor count on a larger die indicates a different density and design approach, with the Intel part using fewer transistors spread across more area.

The core configurations are markedly different. The AMD processor has 6 cores and 12 threads, indicating simultaneous multithreading. The Intel processor has 24 cores and 24 threads, with no multithreading per core. This means the Intel part relies on a higher physical core count rather than thread doubling. The cache hierarchy reflects this difference. The AMD part has 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of shared L3 cache. The Intel part has 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 36 MB of shared L3 cache. The Intel processor therefore has substantially more cache at every level, which contributes to its performance advantage in cache-sensitive workloads.

Clock speeds also differ. The AMD processor has a base clock of 3.40 GHz and a boost clock of 5.00 GHz. The Intel processor has a base clock of 2.50 GHz and a boost clock of 5.60 GHz. Despite a lower base clock, the Intel part achieves a higher boost clock, which partially explains its single-core performance advantage.

The memory subsystems are similar in type but different in bandwidth. Both support DDR5 memory with a dual-channel bus. The AMD processor has a memory bandwidth of 83.2 GB/s, while the Intel processor has 102.4 GB/s. Both support ECC memory. The PCIe connectivity differs, with the AMD part offering Gen 4 with 14 lanes (CPU only) and the Intel part offering Gen 5 with 20 lanes (CPU only). The Intel part therefore provides both newer PCIe generation and more lanes.

The integrated graphics differ as well. The AMD processor uses the Radeon 740M, while the Intel processor uses the Arc Xe-LPG Graphics 64EU. Both are integrated solutions, but they represent different graphics architectures.

The market segments differ: the AMD part is classified as Mobile, while the Intel part is classified as Desktop. This classification aligns with their TDP values: 35 watts for the AMD part and 65 watts for the Intel part. The release dates are also different, with the AMD part released on 2024-04-15 and the Intel part on 2024-12-31.

Head-to-Head Benchmarks

The head-to-head benchmark data shows a consistent pattern of Intel dominance, but the magnitude of the advantage varies significantly by workload type. The largest deltas appear in compute-intensive floating-point and prime number workloads, while the smallest delta appears in single-threaded PassMark testing.

In Cinebench multi-core tests, the Intel Core Ultra 9 285 delivers 4,933 versus 1,854 in R15 multi-core, a delta of -62.4%. In R20 multi-core, the scores are 20,556 versus 7,725, again -62.4%. In R23 multi-core, the scores are 48,945 versus 18,395, also -62.4%. These consistent deltas across Cinebench versions indicate a stable multi-threaded performance gap of roughly 2.66 times in favor of the Intel part. The 24 physical cores versus 6 cores with multithreading explains this magnitude.

Single-core Cinebench results show a similar relative gap. In R15 single-core, the Intel part scores 696 versus 261, a delta of -62.5%. In R20 single-core, the scores are 2,901 versus 1,090, -62.4%. In R23 single-core, the scores are 6,909 versus 2,597, -62.4%. These single-core deltas are nearly identical to the multi-core deltas, which indicates that the Intel architecture holds its advantage even when only one core is active. The higher boost clock of 5.60 GHz versus 5.00 GHz contributes, but the architectural efficiency differences also play a role.

PassMark workloads reveal more varied deltas. The smallest delta appears in PassMark single-thread, where the Intel part scores 4,881 versus 3,909, a delta of -19.9%. This is notably smaller than the Cinebench single-core deltas, suggesting that the PassMark single-thread test is less sensitive to the architectural differences between the two processors. The two identical entries for PassMark single_thread and singlethread confirm the same result.

The largest delta appears in PassMark find prime numbers, where the Intel part scores 459 versus 83, a delta of -81.9%. This workload heavily favors the Intel architecture, likely due to its larger cache and higher core count. Floating-point math shows a delta of -79.9%, with scores of 194,988 versus 39,233. Integer math shows -61.8%, with scores of 164,869 versus 63,045. Extended instructions show -60.3%, with scores of 45,357 versus 17,999.

Data compression shows a delta of -58.7%, with scores of 602,121 versus 248,675. Data encryption shows -69.8%, with scores of 46,949 versus 14,163. Random string sorting shows -57.6%, with scores of 73,651 versus 31,240. Multithread testing shows -62%, with scores of 56,602 versus 21,502. Physics shows -65.6%, with scores of 3,598 versus 1,237.

The data shows that the Intel part leads by roughly 1.25 times in single-thread PassMark, but by 2.5 to 5.5 times in most other workloads. The prime number and floating-point workloads show the largest gaps, which suggests that the Intel part has particular strength in mathematical and algorithmic processing.
