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

The AMD Ryzen 7 PRO 5755G and Intel Core Ultra 9 285 occupy different tiers of the desktop processor market, and the recorded benchmark data reflects a substantial performance gap. The Intel part wins every head-to-head test in the database, but the magnitude of those wins varies widely by workload, which reveals distinct architectural strengths. The Ryzen 7 PRO 5755G is a Zen 3 based 8-core processor on the AMD Socket AM4 platform, while the Core Ultra 9 285 is an Arrow Lake based 24-core processor on Intel Socket 1851. Both carry a 65 watt TDP, but the Intel chip ships with a launch MSRP of $579.

Head-to-Head Benchmarks

The single-thread results establish the most immediate difference. In the PassMark single-thread test, the Intel Core Ultra 9 285 scores 4881, while the AMD Ryzen 7 PRO 5755G scores 3366, a margin of 31 percent in favor of Intel. This is the smallest relative gap in the entire head-to-head set, which suggests that the Ryzen's Zen 3 core design remains competitive in lightly threaded work despite being an older architecture. Still, Intel's 5.60 GHz boost clock against AMD's 4.60 GHz boost clock helps explain the advantage, even though the database records only the scores, not the clock ratio.

The multithreaded results widen the gap considerably. In PassMark multithread, Intel scores 56602 against AMD's 23858, a 57.8 percent difference. The integer math test shows a similar pattern, with Intel at 164869 versus AMD at 90270, a 45.2 percent lead. Floating point math tells an even more decisive story, Intel scores 194988 while AMD manages 50778, a 74 percent advantage. The floating point result is particularly striking because it indicates the Core Ultra 9 285 is not merely adding more cores, it is also processing each floating point operation more efficiently than the Zen 3 design.

Architecture Differences

The two processors come from different architectural generations and use different manufacturing processes. The AMD Ryzen 7 PRO 5755G uses the Zen 3 architecture with the Cezanne codename, built on a 7 nm process at TSMC. The Intel Core Ultra 9 285 uses the Arrow Lake architecture with the Arrow Lake-S codename, built on a 3 nm process, also at TSMC. The node difference is significant, as the 3 nm process allows Intel to pack more transistors into a similar die area. The Intel chip contains 17,800 million transistors on a 243 mm² die, while the AMD chip contains 10,700 million transistors on a 180 mm² die.

Core organization differs fundamentally. The AMD part uses 8 cores with 16 threads, meaning each core supports two threads via simultaneous multithreading. The Intel part uses 24 cores with 24 threads, meaning it has no multithreading per core and relies entirely on physical core count. Despite having no SMT, the Intel part still achieves far higher multithreaded scores, which indicates that the 24 physical cores generate more parallel throughput than AMD's 8 cores with 16 threads.

Cache hierarchies show a clear structural difference. The AMD part uses 64 KB of L1 cache per core, 512 KB of L2 cache per core, and 16 MB of L3 cache. The Intel part uses 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 36 MB of shared L3 cache. The Intel L2 cache is particularly notable, as 3 MB per core is six times the per-core L2 allocation of the AMD chip. The larger on-die caches likely contribute to the Intel part's strong showing in data compression and encryption workloads, where working sets can fit in cache.

Memory architecture also diverges. The AMD Ryzen 7 PRO 5755G supports DDR4 memory on a dual-channel bus with 51.2 GB/s bandwidth. The Intel Core Ultra 9 285 supports DDR5 memory on a dual-channel bus with 102.4 GB/s bandwidth, exactly double the AMD figure. ECC memory support is present on the Intel chip but absent on the AMD chip. PCIe connectivity differs as well, with the AMD part providing Gen 3 with 16 lanes from the CPU, while the Intel part provides Gen 5 with 20 lanes from the CPU. The integrated graphics also differ, with AMD using Radeon Vega 8 and Intel using Arc Xe-LPG Graphics 64EU.

Specification Differences

The core and thread counts are the most obvious specification split. The AMD Ryzen 7 PRO 5755G has 8 cores and 16 threads. The Intel Core Ultra 9 285 has 24 cores and 24 threads. The base clock favors AMD, which runs at 3.80 GHz versus Intel's 2.50 GHz. The boost clock favors Intel, which reaches 5.60 GHz versus AMD's 4.60 GHz. Both processors have a 65 watt TDP, so the power envelope is identical, even though the Intel part delivers substantially more performance within that envelope.

The socket and platform are entirely different. The AMD part uses AMD Socket AM4, which is a mature platform with DDR4 support. The Intel part uses Intel Socket 1851, which pairs with DDR5 memory. The process node differs, with AMD on 7 nm and Intel on 3 nm. Transistor count and die size both favor Intel, with 17,800 million transistors on a 243 mm² die versus 10,700 million transistors on a 180 mm² die.

Cache specifications differ in every level. The AMD L1 is 64 KB per core, the Intel L1 is 192 KB per core. The AMD L2 is 512 KB per core, the Intel L2 is 3 MB per core. The AMD L3 is 16 MB, the Intel L3 is 36 MB shared. Memory support differs by generation, with DDR4 for AMD and DDR5 for Intel, and the bandwidth figures follow, 51.2 GB/s versus 102.4 GB/s. ECC memory is supported only on the Intel part. PCIe generation and lane count differ, with Gen 3 and 16 lanes for AMD versus Gen 5 and 20 lanes for Intel. The integrated GPU differs, Radeon Vega 8 for AMD and Arc Xe-LPG Graphics 64EU for Intel. The AMD part has no recorded launch MSRP, while the Intel part has a launch MSRP of $579. The release dates differ by several months, with the AMD part released in September 2024 and the Intel part released in December 2024. Neither processor has an unlocked multiplier, so both are locked for overclocking.

Where Each One Wins

The recorded data gives the Intel Core Ultra 9 285 a win in every single test, so a workload-based split must consider the margin of victory rather than the direction. The Intel part wins by its smallest margin, 31 percent, in the single-thread test. This means the AMD Ryzen 7 PRO 5755G is the closer competitor in lightly threaded applications, where the gap narrows to less than a third. For legacy software that uses one or two threads, the AMD part is less disadvantaged than in heavily parallel tasks.

The Intel part wins by its largest margin, 87.4 percent, in the prime number finding test. This workload is computationally intensive and highly parallel, which plays directly to the Intel part's 24 physical cores. The floating point math test shows a 74 percent advantage for Intel, and the physics test shows a 71.6 percent advantage. These results indicate that the Intel part is the stronger choice for scientific computing, simulation, and any workload that relies on floating point throughput.

The data compression and encryption tests show Intel leading by roughly 51 to 59 percent. These workloads benefit from the Intel part's larger caches and higher memory bandwidth. The random string sorting test, which is memory latency sensitive, shows Intel ahead by 55.5 percent. The extended instructions test, which measures SIMD and vector processing, shows Intel ahead by 54.8 percent. The integer math test shows the smallest multithreaded gap at 45.2 percent, but Intel still leads by a wide margin.

The AMD Ryzen 7 PRO 5755G does not win any category, but its performance profile is not without merit. The 31 percent single-thread gap means the AMD part is a reasonable option for older applications that cannot use many cores. The 45.2 percent integer math gap is the smallest multithreaded deficit, suggesting the AMD part handles integer-heavy work relatively better than floating point work. The AMD part also uses DDR4 memory, which means it can be paired with older, more common memory modules, and it uses the AM4 socket, which is a widely deployed platform.

The Verdict

The data points to a clear performance hierarchy. The Intel Core Ultra 9 285 is the faster processor in every recorded benchmark, with an average score of 75488 against 49196 for the AMD Ryzen 7 PRO 5755G. The Intel part sits at the 95th percentile of all CPUs, while the AMD part sits at the 90th percentile. The Intel part's nearest rivals are EPYC server processors and Ryzen 7 PRO 9755 series parts, all within 0.3 percent of its average score. The AMD part's nearest rivals are mid-range desktop chips like the Ryzen 9 7900 and Core i5-14600KF, all within 1 percent.

For workloads that demand maximum multithreaded throughput, the Intel Core Ultra 9 285 is the only choice between these two, based on the recorded data. It leads by 57.8 percent in multithread, by 74 percent in floating point math, and by 87.4 percent in prime number finding. For users constrained to the AM4 platform or DDR4 memory, the AMD Ryzen 7 PRO 5755G offers a functioning alternative, but the benchmark results show it trails by at least 31 percent in every test. The Intel part also supports ECC memory, provides Gen 5 PCIe with 20 lanes, and doubles the memory bandwidth, all of which are confirmed by the specification data. The AMD part has a lower base clock but a higher thread count per core, yet the overall scores show that the Intel part's 24 physical cores overcome its lack of SMT. The verdict from the database is unambiguous, the Intel Core Ultra 9 285 delivers superior performance across every measured workload, while the AMD Ryzen 7 PRO 5755G remains competitive only in the narrow sense of being less far behind in single-thread tests.
