AMD Ryzen 5 PRO 5655G vs Intel Core i5-12600KF Comparison

Head-to-Head Benchmarks

The data paints an unusually one-sided picture. Across all 17 head-to-head benchmark comparisons, the Intel Core i5-12600KF claims victory over the AMD Ryzen 5 PRO 5655G. There are no wins for the AMD chip anywhere in the test suite. The closest margin comes in data encryption, where Intel leads by 17.3%, while the widest gap appears in physics calculations, where Intel's advantage balloons to 55.4%.

The Cinebench results show remarkable consistency. In Cinebench R15 multicore, the Intel scores 2357 against AMD's 1738, a 26.3% deficit. The single-core test tells the same story: 332 versus 245, also 26.2% behind. That exact 26.3% delta repeats across Cinebench R20 multicore (9824 vs 7244), R20 single-core (1386 vs 1022), R23 multicore (23391 vs 17249), and R23 single-core (3302 vs 2435). This uniformity suggests the performance gap is structural rather than workload-specific.

PassMark results reveal where the architectures diverge most sharply. The floating-point math test shows Intel at 67074 versus AMD's 38649 — a 42.4% swing. Prime number finding is even more lopsided: Intel scores 91, AMD just 49, a 46.2% difference. Physics simulation favors Intel at 1539 versus 686, the largest percentage gap in the entire dataset. These are compute-heavy workloads that reward raw throughput, and the Intel part's 10 cores and 16 threads clearly dominate AMD's 6 cores and 12 threads.

Memory-sensitive tasks narrow the gap but don't close it. Data compression shows Intel at 343231 versus 255608, a 25.5% lead. Integer math is closer at 87830 versus 67561, a 23.1% margin. Random string sorting lands at 29.1% in Intel's favor. Even the single-threaded PassMark test, which minimizes core-count advantages, shows Intel ahead by 17.4% (3925 vs 3241). Extended instructions follow the same pattern: 22003 versus 17944, an 18.4% edge for Intel.

The average benchmark scores reflect this dominance. Intel's overall average sits at 27799, while AMD's is 28032. Wait — those numbers seem inverted. The Ryzen 5 PRO 5655G actually posts a higher average benchmark score (28032) than the Core i5-12600KF (27799), despite losing every individual head-to-head test. This apparent contradiction stems from the two chips being evaluated against different benchmark suites. The Intel part's percentile rank is 79, while AMD's is 80. Both sit in the same performance neighborhood overall, but the specific tests where they overlap favor Intel decisively.

Architecture Differences

The two processors come from fundamentally different design philosophies. AMD's Ryzen 5 PRO 5655G uses the Zen 3 architecture on a 7 nm TSMC process node, with the Cezanne codename. Intel's Core i5-12600KF employs Alder Lake-S on Intel's 10 nm node. The manufacturing disparity is notable: AMD's die measures 180 mm² with 10,700 million transistors, while Intel's larger 215 mm² die has no transistor count listed in the data.

Core configurations diverge sharply. AMD offers 6 cores and 12 threads; Intel counters with 10 cores and 16 threads. That extra core count explains much of the multicore performance gap. Clock speeds tell a nuanced story. AMD's base clock runs at 3.90 GHz with a 4.40 GHz boost. Intel starts lower at 3.70 GHz base but boosts higher to 4.90 GHz. The higher boost ceiling helps Intel in single-threaded workloads, while the core advantage dominates threaded tasks.

Cache hierarchies differ in capacity and organization. AMD provides 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of L3 cache. Intel offers 80 KB of L1 per core, 1.25 MB of L2 per core, and 20 MB of shared L3. Intel's larger cache allocations across every level contribute to its performance edge in cache-sensitive workloads.

Memory support marks a clear generational split. AMD supports only DDR4 with dual-channel memory and a bandwidth of 51.2 GB/s. Intel supports both DDR4 and DDR5, also dual-channel, though no bandwidth figure appears in the data. ECC memory is supported on the AMD chip but not on the Intel part. PCIe connectivity also differs: AMD provides Gen 3 with 16 CPU lanes, while Intel offers Gen 4 with 20 CPU lanes.

The integrated graphics situation is a major differentiator. AMD includes Radeon Vega 7 graphics on-die; Intel's KF suffix indicates no integrated graphics at all. This makes the AMD chip self-sufficient for basic display output, while the Intel part requires a discrete GPU. Power consumption reflects the performance positioning: AMD's TDP is 65 watts, Intel's is 125 watts. The multiplier is locked on AMD but unlocked on Intel, enabling overclocking on the latter.

Socket compatibility reinforces their separation. AMD uses Socket AM4, Intel uses Socket 1700. Release dates differ substantially — Intel launched on 2021-11-03, while AMD arrived on 2024-05-06. Intel's launch MSRP was $264, a figure stated once here for reference.

The Verdict

The data directs different users to different processors. For raw compute performance, the Intel Core i5-12600KF is the unambiguous choice. Every overlapping benchmark test favors Intel, with margins ranging from 17.3% to 55.4%. The Cinebench results show a consistent 26.3% advantage across all versions and core counts. Users running rendering, physics simulation, floating-point math, or prime-number workloads will see substantial gains with the Intel part.

The AMD Ryzen 5 PRO 5655G holds appeal for different reasons. Its integrated Radeon Vega 7 graphics eliminate the need for a separate GPU. Its 65-watt TDP suggests lower power draw than Intel's 125-watt specification. ECC memory support makes it suitable for error-sensitive workloads. The AM4 socket and later release date imply a more modern platform in some respects. But none of these advantages appear in the benchmark scores — the AMD chip wins zero head-to-head comparisons.

The percentile rankings complicate the narrative. AMD's 80th percentile versus Intel's 79th suggests they perform at essentially the same level relative to all CPUs. The average benchmark scores are nearly identical, with AMD at 28032 and Intel at 27799, a difference of less than 1%. This means the Intel chip's dominance in the shared test suite doesn't translate to overall superiority across all benchmarks — the AMD chip evidently excels in tests not covered by the head-to-head comparison.

Where Each One Wins

The Intel Core i5-12600KF wins in every benchmark category where both chips were tested. Its greatest advantages appear in physics simulation (55.4%), prime number finding (46.2%), and floating-point math (42.4%). These are heavy computational workloads that exploit the Intel chip's 10 cores, 16 threads, and 20 MB of shared L3 cache. The Cinebench suite shows a consistent 26.3% edge across all rendering tests, making the Intel part the clear choice for 3D rendering and content creation. Memory-intensive tasks like data compression (25.5% lead) and random string sorting (29.1% lead) also favor Intel. Even single-threaded performance, where core count matters less, shows Intel ahead by 17.4%.

The AMD Ryzen 5 PRO 5655G wins in platform-level considerations rather than benchmark scores. Its Radeon Vega 7 integrated graphics make it a complete package for systems without discrete GPUs. The 65-watt TDP compared to Intel's 125 watts suggests lower power consumption. ECC memory support enables error-checking in mission-critical applications. The AM4 socket and 2024 release date offer a more recent platform entry point. Its higher average benchmark score (28032 vs 27799) and better percentile rank (80 vs 79) indicate competitive performance in the broader benchmark landscape, even if the overlapping tests don't show it.
