AMD Ryzen 5 PRO 6650U vs Intel Core Ultra 5 228V Comparison

Where Each One Wins

The benchmark split between the AMD Ryzen 5 PRO 6650U and the Intel Core Ultra 5 228V is heavily one-sided, but the two wins for AMD land in areas that matter for specific workloads. The Intel part takes 13 of the 15 head-to-head comparisons, while AMD claims 2.

AMD’s victories come in integer math and data compression. The Ryzen 5 PRO 6650U scores 60045 in Passmark integer math, which is 51.3% ahead of the Intel chip’s 39679. That is a massive margin in a category that reflects general arithmetic and logic-heavy processing. In data compression, AMD posts 190180 versus Intel’s 173924, a 9.3% advantage. These are the two areas where the AMD silicon’s architecture and thread configuration clearly carry the day.

Intel’s wins cover nearly everything else, including all three Cinebench tests, both single-thread Passmark entries, floating-point math, encryption, extended instructions, prime number finding, physics simulation, multithread performance, and random string sorting. The largest Intel margins appear in prime number finding (69% ahead), physics (45.6% ahead), and floating-point math (38.9% ahead). These are compute-heavy, single-core-sensitive tasks where Intel’s newer architecture and higher per-core efficiency show through.

For a user deciding between these two, the split suggests AMD for integer-heavy compression workloads and Intel for almost everything else, particularly floating-point, physics, and single-threaded responsiveness. The data does not show a balanced contest; it shows a specialist AMD part versus a generalist Intel part.

Architecture Differences

The two processors come from different design philosophies and manufacturing generations. The AMD Ryzen 5 PRO 6650U is built on Zen 3+ architecture with the Rembrandt codename, using a 6 nm process from TSMC. It has 6 cores and 12 threads, meaning it relies on simultaneous multithreading to reach its thread count. The Intel Core Ultra 5 228V uses Lunar Lake architecture on a 3 nm TSMC process, with 8 cores and 8 threads, meaning it has no multithreading. Intel’s core count is higher, but its thread count is lower.

Cache layouts differ substantially. AMD provides 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of shared L3 cache. Intel uses 192 KB of L1 per core, 2.5 MB of L2 per core, and only 8 MB of shared L3. Intel’s per-core L2 is five times larger in capacity, which likely helps its single-thread performance, while AMD’s L3 is double the size, which can benefit shared workloads.

Clock speeds show a similar base but different boost behavior. Both CPUs reach a 4.50 GHz boost clock. The AMD base clock is 2.90 GHz, while the Intel base clock is 2.10 GHz. Intel’s lower base clock with the same boost suggests a wider operating range. The AMD chip carries a 15 W TDP, and the Intel chip is rated at 17 W.

Memory support diverges as well. AMD uses DDR5 with dual-channel memory and a recorded bandwidth of 76.8 GB/s. Intel’s memory support is listed as unknown and dependent on motherboard, though it also uses dual-channel memory. PCIe generations differ: AMD offers Gen 4 with 20 lanes, while Intel offers Gen 5 with only 4 lanes. Integrated graphics also differ, with AMD using Radeon 660M and Intel using Arc 130V. Both are mobile parts without unlocked multipliers, and both are currently in active production.

Head-to-Head Benchmarks

The Cinebench results show Intel ahead across the board, but the margins vary. In Cinebench R15 multicore, Intel scores 1502.5 against AMD’s 1459.5, a 2.9% gap. The single-core R15 test shows a larger divide: Intel at 267 versus AMD at 232.5, which is 12.9% ahead. Cinebench R23 multicore puts Intel at 9932 versus AMD’s 8854, a 10.9% margin, and the R23 single-core test gives Intel 1758 against AMD’s 1463, a 16.8% lead.

Passmark single-thread results reinforce the single-core picture. Intel scores 3836 in both Passmark single-thread and single_thread entries, while AMD scores 3149 in both, giving Intel a 17.9% advantage. This is the consistent theme: Intel wins every single-threaded test by double-digit margins.

The multithread result is closer. Passmark multithread shows Intel at 18227 versus AMD’s 16429, a 9.9% lead. This is narrower than the single-thread gap, suggesting AMD’s extra threads (12 versus 8) help close the distance in parallel work, but not enough to overtake Intel.

Floating-point math is a decisive Intel win: 53310 versus 32571, a 38.9% margin. Physics simulation follows at 1538 versus 837, a 45.6% gap. Extended instructions show Intel at 14801 against AMD’s 12261, a 17.2% lead. Data encryption favors Intel by 6.7%, with scores of 13032 and 12159. Random string sorting gives Intel a modest 4.5% edge, 21254 to 20299.

AMD’s two wins are worth restating for emphasis. Integer math: 60045 versus 39679, a 51.3% advantage. Data compression: 190180 versus 173924, a 9.3% edge. These are the only tests where AMD leads, and the integer margin is the single largest delta in either direction across all 15 comparisons.

The Verdict

The recorded data points to a clear recommendation for most buyers: the Intel Core Ultra 5 228V is the stronger processor in the majority of measured workloads. It wins 13 of 15 benchmarks, including all Cinebench tests, all single-thread tests, and the multithread Passmark result. Its advantages range from 2.9% to 69%, with the largest margins in prime number finding, physics, and floating-point math. The Intel chip also reaches the same 4.50 GHz boost clock as AMD while using a newer 3 nm process and a larger L2 cache per core.

The AMD Ryzen 5 PRO 6650U should be chosen only by users whose workloads are dominated by integer math and data compression. The 51.3% lead in integer math is substantial, and the 9.3% lead in data compression is meaningful for archiving or database workloads. AMD’s 12 threads also help it stay competitive in multithreaded tests, where it trails by less than 10% despite losing every single-thread test by double digits.

Neither chip has an unlocked multiplier, and both are mobile parts in active production. The AMD part uses a 15 W TDP versus Intel’s 17 W, which may matter for battery life in thin laptops. The AMD chip offers 20 PCIe Gen 4 lanes, while Intel offers only 4 Gen 5 lanes. For users who need PCIe bandwidth, AMD has the advantage on paper. For users who prioritize raw compute across a broad range of tasks, Intel is the data-backed choice.
