AMD Ryzen 5 PRO 6650U vs Intel Core i7-11700F Comparison

The Intel Core i7-11700F and the AMD Ryzen 5 PRO 6650U are both 75th-percentile performers, yet they are fundamentally different chips. The data shows a complete sweep: the desktop-oriented i7-11700F wins all 17 head-to-head benchmark comparisons, leaving the mobile-focused Ryzen 5 PRO 6650U without a single victory. This is not a close contest; it is a categorical performance gap defined by power envelope and design intent.

Head-to-Head Benchmarks

The most dramatic margin between the two processors appears in multi-threaded workloads, where the Intel part's core and thread advantage becomes overwhelming. In Cinebench R23 multi-core, the i7-11700F scores 17633 against the Ryzen's 8854, a staggering 99.2% delta. This is nearly double the performance, and it highlights the difference between an 8-core, 16-thread desktop chip and a 6-core, 12-thread mobile part. The Geekbench multi-core result tells a similar story: 9680 for Intel versus 7065 for AMD, a 37% lead. PassMark's multithread test shows a 26.2% gap (20728 vs 16429), while integer math (79133 vs 60045) and floating-point math (46307 vs 32571) favor Intel by 31.8% and 42.2%, respectively.

The single-threaded results are closer, but Intel still holds a decisive edge. In Cinebench R23 single-core, the i7-11700F scores 2489, which is 70.1% ahead of the Ryzen's 1463. That is a massive per-core delta, not just a count advantage. Geekbench single-core shows a 14.5% lead (1891 vs 1652), while PassMark single-thread is a tighter 3.6% margin (3262 vs 3149). The Cinebench R15 single-core test also goes Intel's way, with 250 versus 232.5, a 7.5% win. These results suggest the Rocket Lake architecture's high boost clock of 4.90 GHz outpaces the Zen 3+ part's 4.50 GHz boost in lightly threaded tasks, though the gap narrows considerably when only a few cores are active.

Memory and data-heavy workloads follow the same pattern. PassMark's data compression test shows Intel at 266035 versus AMD's 190180, a 39.9% advantage. Random string sorting is even more lopsided, with Intel winning by 50.2% (30498 vs 20299). Extended instruction sets (SIMD-style workloads) see a 49.3% delta (18308 vs 12261). The smallest margins appear in encryption (3.3%, 12563 vs 12159), physics (5.7%, 885 vs 837), and prime number finding (7.7%, 56 vs 52). In every single measured category, the i7-11700F is faster. The Ryzen 5 PRO 6650U never comes out ahead, even in tasks where mobile chips typically excel.

Architecture Differences

The two processors represent opposite ends of the design spectrum. The Intel Core i7-11700F is built on Rocket Lake, a 14 nm process from Intel's own foundry, with a die size of 276 mm². It is a desktop part with a 65 W TDP, socketed in Intel Socket 1200, and released in March 2021. It offers 8 cores and 16 threads, with a base clock of 2.50 GHz and a boost clock of 4.90 GHz. Its cache layout includes 80 KB of L1 per core, 512 KB of L2 per core, and a shared 16 MB L3. Memory support is DDR4 over a dual-channel bus, providing 51.2 GB/s of bandwidth. It has no integrated graphics, making it a pure CPU that requires a discrete GPU.

The AMD Ryzen 5 PRO 6650U, by contrast, is a mobile part built on Zen 3+ (codenamed Rembrandt) using TSMC's 6 nm process, with a smaller die size of 208 mm². It packs 6 cores and 12 threads, a base clock of 2.90 GHz, and a boost clock of 4.50 GHz. Its TDP is just 15 W, reflecting its ultrabook target. Cache is 64 KB L1 per core, 512 KB L2 per core, and the same 16 MB of shared L3. Crucially, it supports DDR5 memory with a dual-channel bus, delivering 76.8 GB/s of bandwidth — 50% more than the Intel part. It also includes integrated Radeon 660M graphics, which the i7-11700F lacks entirely. Both support PCIe Gen 4 with 20 lanes, and neither has ECC memory or an unlocked multiplier.

The process node difference is stark: 14 nm (Intel) versus 6 nm (TSMC). This explains the power disparity — 65 W versus 15 W — and the die size difference. The AMD chip achieves higher memory bandwidth thanks to DDR5, yet it still loses every benchmark. The Intel part's higher boost clock and extra two cores provide a raw compute advantage that memory bandwidth cannot offset. The Ryzen is built for efficiency and mobility, while the Intel is built for sustained desktop performance. Neither supports ECC, and both are limited to Gen 4 PCIe. The i7-11700F is marked end-of-life, while the Ryzen 5 PRO 6650U remains active in production.

The Verdict

The data is unambiguous: the Intel Core i7-11700F is the faster processor in every benchmark recorded. With 17 wins and zero losses, it dominates across single-core, multi-core, and specialized workloads. The 99.2% lead in Cinebench R23 multi-core is the single largest margin, underscoring the benefit of 8 cores versus 6. For anyone building a desktop system where raw performance is the sole criterion, the i7-11700F is the correct choice. Its 75th-percentile ranking is identical to the Ryzen's, but the benchmark scores within that percentile are consistently higher.

The AMD Ryzen 5 PRO 6650U is not without merit, but its advantages do not show up in raw compute benchmarks. It offers a 15 W TDP versus 65 W, making it far more suitable for thin-and-light laptops. It has integrated Radeon 660M graphics, enabling systems without a discrete GPU. It supports faster DDR5 memory at 76.8 GB/s, which future-proofs memory bandwidth. But the data shows that these features do not translate into higher CPU performance in any of the 17 tests. The nearest rival data confirms the gap: the i7-11700F sits alongside the AMD Ryzen 5 3600X (deltaPct 0), while the Ryzen 5 PRO 6650U is compared to the Intel Core i7-11700 (deltaPct -0.1), which is essentially the same chip as the F variant but with integrated graphics.

Where Each One Wins

The Intel Core i7-11700F wins in every scenario that requires computational throughput. For multi-core rendering, the Cinebench R23 result (17633 vs 8854) makes it almost twice as fast as the Ryzen for video encoding or 3D scene building. For data-heavy tasks, its 39.9% lead in compression (266035 vs 190180) and 50.2% lead in random string sorting (30498 vs 20299) make it the better pick for database work or file archiving. For scientific computing, the 42.2% advantage in floating-point math (46307 vs 32571) and 49.3% advantage in extended instructions (18308 vs 12261) point to superior SIMD and heavy number-crunching capability. Even in lightly threaded tasks, the 70.1% Cinebench R23 single-core lead (2489 vs 1463) means the Intel part feels snappier in everyday desktop applications.

The AMD Ryzen 5 PRO 6650U has no benchmark wins, but its design wins are implicit in the architecture. Its 15 W TDP is 50 W lower than the Intel part, making it the only viable choice for fanless or ultra-portable laptop designs. The integrated Radeon 660M graphics provide a complete system-on-chip solution, eliminating the need for a separate GPU. Its DDR5 memory bus at 76.8 GB/s offers higher theoretical bandwidth, which could benefit future workloads that are memory-latency sensitive. The 6 nm process node and smaller 208 mm² die size suggest better power efficiency per transistor, though the benchmark data does not capture battery life or thermal output. For a user prioritizing mobility, silence, and an all-in-one package, the Ryzen 5 PRO 6650U is the logical selection. For anyone prioritizing raw CPU speed, the Intel Core i7-11700F is the only choice based on this data.
