AMD Ryzen 5 PRO 8645HS vs Intel Core 5 221TE Comparison

Head-to-Head Benchmarks

The recorded data shows a comprehensive victory for the AMD Ryzen 5 PRO 8645HS across all 17 benchmark comparisons. The Intel Core 5 221TE does not register a single win in any tested workload. The average benchmark score gap is substantial: the AMD part averages 30,879 points versus 17,860 for the Intel part, placing the AMD chip in the 82nd percentile of all CPUs while the Intel chip sits in the 71st percentile.

The largest single-core advantage appears in PassMark single-thread testing, where the AMD processor scores 3,858 against Intel's 1,734, a 122.5% delta. Cinebench single-core results follow the same pattern: R23 single-core shows AMD at 2,787 versus Intel at 1,596, a 74.6% delta. R20 single-core shows 1,170 versus 670, also a 74.6% delta. R15 single-core shows 280 versus 160, a 75% delta. The consistency of these percentages across Cinebench versions indicates a stable architectural advantage rather than a workload-specific anomaly.

Multi-core results confirm the same hierarchy. In Cinebench R23 multi-core, the AMD Ryzen 5 PRO 8645HS scores 19,742 against the Intel Core 5 221TE's 11,305, a 74.6% delta. R20 multi-core shows 8,291 versus 4,748, and R15 multi-core shows 1,989 versus 1,139, both with the same 74.6% delta. PassMark multi-thread testing gives AMD 23,569 versus Intel's 13,301, a 77.2% delta.

The encryption workload delivers the second-largest margin. AMD scores 17,387 in PassMark data encryption against Intel's 8,963, a 94% delta. Extended instruction testing shows AMD at 21,212 versus 9,655, a 119.7% delta, indicating a particularly strong showing in SIMD and specialized instruction throughput. Random string sorting follows closely at 35,472 versus 16,929, a 109.5% delta.

Integer math favors AMD at 72,740 versus 42,303, a 71.9% delta. Floating-point math shows 45,481 versus 31,661, a 43.6% delta. Data compression yields 265,826 versus 156,682, a 69.7% delta. The smallest margins appear in prime number finding (73 versus 59, a 23.7% delta) and physics simulation (1,208 versus 977, a 23.6% delta), though both still clearly favor AMD.

The Verdict

The benchmark data indicates a decisive performance hierarchy. The AMD Ryzen 5 PRO 8645HS outperforms the Intel Core 5 221TE in every recorded test, with deltas ranging from 23.6% to 122.5%. The average benchmark score difference of 13,019 points (30,879 versus 17,860) places these processors in different performance tiers entirely.

The AMD part's nearest rivals in the database are the AMD Ryzen 7 8700F (30,746, 0.4% lower), Intel Core i7-13700TE (31,028, 0.5% higher), AMD Ryzen 9 8945HS (31,074, 0.6% higher), and Intel Core i7-12700F (31,081, 0.6% higher). This clustering shows the Ryzen 5 PRO 8645HS competes with higher-core-count desktop and mobile parts, despite being a 6-core mobile processor.

The Intel Core 5 221TE's nearest rivals are the AMD Ryzen 5 3600XT (17,891, 0.2% higher), Intel Core 5 120U (17,898, 0.2% higher), Intel Core 7 350 (17,779, 0.5% lower), and AMD Ryzen 5 1600 (17,994, 0.7% higher). These are older or lower-tier processors, confirming the 221TE sits in a much lower performance bracket.

For users selecting between these two, the data supports the AMD processor without qualification. The Intel part's only advantage in the specification sheet is its higher core and thread count (10 cores, 16 threads versus 6 cores, 12 threads), yet this does not translate into any benchmark win. The AMD chip's higher base clock (4.30 GHz versus 1.80 GHz) and equal boost clock (5.00 GHz for both) appear to drive the single-core dominance, while the Zen 4 architecture's efficiency sustains the multi-core lead despite fewer physical cores.

Where Each One Wins

The AMD Ryzen 5 PRO 8645HS wins every measured category, so the use-case split is defined by the magnitude of its advantage rather than by any Intel win.

For single-threaded responsiveness, the AMD part's 122.5% lead in PassMark single-thread and 74.6-75% leads across all Cinebench single-core tests make it the clear choice for latency-sensitive applications like interactive workloads, UI rendering, and lightly threaded legacy software. The 4.30 GHz base clock versus 1.80 GHz gives it a structural advantage that no Intel configuration can overcome.

For multi-threaded rendering, the AMD part's 74.6% lead in all three Cinebench multi-core tests (R15, R20, R23) and 77.2% lead in PassMark multi-thread indicate strong scaling across its 12 threads. Despite having 4 fewer threads than the Intel part (12 versus 16), the AMD chip delivers substantially higher throughput, likely due to the 4 nm process node versus Intel's 10 nm node.

For data-heavy workloads, the AMD part shows 69.7% higher compression throughput, 94% higher encryption throughput, and 119.7% higher extended instruction performance. These metrics matter for database operations, file archiving, and cryptography. The 43.6% floating-point lead and 71.9% integer math lead cover scientific and general computation respectively.

The Intel Core 5 221TE has no benchmark category where it leads. Its only notable specification advantages are core count (10 versus 6), thread count (16 versus 12), L3 cache (24 MB versus 16 MB), larger L1 and L2 per-core caches (80 KB and 1.25 MB versus 64 KB and 1 MB), and PCIe Gen 5 support. None of these translate into a recorded performance win.
