AMD Ryzen 5 PRO 4650U vs Intel Core i3-9320 Comparison

The AMD Ryzen 5 PRO 4650U and Intel Core i3-9320 land within 0.1% of each other in average benchmark score, yet they are fundamentally different processors in almost every other measurable way. The Ryzen 5 PRO 4650U is a 6-core, 12-thread Zen 2 mobile part with a 15W TDP, while the Core i3-9320 is a 4-core, 4-thread Coffee Lake desktop chip with a 62W TDP. Both sit at the 42nd percentile among all CPUs, meaning their aggregate performance is statistically indistinguishable, but the head-to-head data reveals stark differences in workload-specific behavior.

Head-to-Head Benchmarks

The available head-to-head results show a decisive sweep for the AMD Ryzen 5 PRO 4650U. In Cinebench R15 multi-core, the AMD part scores 1161 against the Intel’s 630, a delta of 84.3% in favor of the Ryzen. This is not a marginal gap; it is a near-doubling of output in a heavily threaded render workload. The single-core result is even more lopsided in percentage terms: the Ryzen 5 PRO 4650U scores 175 versus 88 for the Core i3-9320, a 98.9% advantage. That the AMD chip wins single-core by such a wide margin is notable because the Intel part has a higher boost clock (4.40 GHz versus 4.00 GHz) and a higher base clock (3.70 GHz versus 2.10 GHz), yet still trails massively.

These two data points dominate the comparison because they are the only shared benchmark results between the two processors. The Ryzen 5 PRO 4650U also has Geekbench scores of 4692 multi-core and 1211 single-core, while the Core i3-9320 has no corresponding Geekbench entries in the data; instead, Intel’s chip offers Cinebench R20 (2626 multi-core, 370 single-core) and R23 (6254 multi-core, 882 single-core) results that the AMD part lacks. The average benchmark scores are nearly identical — 1810 for AMD and 1808 for Intel — which masks the fact that the two chips excel in different test suites. The deltaPct between them is just 0.1%, a tie in aggregate terms, but the Cinebench R15 results show a 84.3% and 98.9% split in AMD’s favor, suggesting the tests that favor Intel are either not present in the shared set or that Intel’s strengths lie elsewhere.

Architecture Differences

The architectural chasm between these two CPUs explains the benchmark split. The Ryzen 5 PRO 4650U is built on TSMC’s 7 nm process node with 9,800 million transistors on a 156 mm² die, using the Zen 2 architecture under the Renoir codename. The Core i3-9320 uses Intel’s 14 nm process, with a 126 mm² die size, and is based on the older Coffee Lake architecture. Node size alone does not dictate performance, but it correlates with power efficiency and transistor density, and the data supports that: AMD delivers 6 cores and 12 threads within a 15W TDP, while Intel fits only 4 cores and 4 threads into a 62W TDP.

Cache configurations differ in the L2 tier. Both share 64 KB of L1 per core and 8 MB of shared L3, but the Ryzen 5 PRO 4650U has 512 KB of L2 per core, whereas the Core i3-9320 has 256 KB per core. That doubles the per-core L2 on the AMD side, which can improve latency-sensitive workloads. Memory bandwidth also favors AMD: 68.3 GB/s versus 38.4 GB/s, despite both using dual-channel DDR4. The integrated graphics differ as well — the Radeon RX Vega 6 on the AMD side versus Intel’s UHD Graphics 630. The AMD part supports ECC? No, the data lists `eccMemory: false` for the Ryzen 5 PRO 4650U, while the Core i3-9320 supports ECC memory (`eccMemory: true`). PCIe is Gen 3 for both, but Intel specifies 16 lanes on the CPU, while AMD’s lane count is not specified.

Market positioning diverges sharply: the Ryzen 5 PRO 4650U is a mobile part for AMD Socket FP6, released in May 2020, and remains in active production. The Core i3-9320 is a desktop processor for Intel Socket 1151, released in April 2019, and is now end-of-life. The Intel chip has a launch MSRP of $154, which is noted once here; the AMD part has no launch MSRP listed. The AMD chip is part of the 4000 series with a Renoir generation identifier, while the Intel chip is a Coffee Lake Refresh part. Neither has an unlocked multiplier, so overclocking is not a differentiator.

The Verdict

From the data, the Ryzen 5 PRO 4650U is the clear winner in the shared benchmarks, with an 84.3% lead in multi-core and a 98.9% lead in single-core Cinebench R15. If those were the only tests that mattered, the verdict would be unilateral. However, the aggregate scores tell a different story: both CPUs sit at the 42nd percentile, and their average benchmark scores differ by 0.1%. This suggests that the Intel chip performs competitively in other test suites not captured in the head-to-head set — specifically, the Core i3-9320’s Cinebench R20 and R23 results (2626 and 6254 multi-core, respectively) show it is not a weak processor in threaded workloads, though the Ryzen’s scores for those tests are absent.

The Ryzen 5 PRO 4650U is the pick for users who prioritize the workloads represented by Cinebench R15 — heavy multi-threaded rendering and single-thread responsiveness — and who need a low-power mobile solution. The Core i3-9320 is the pick for users who need ECC memory support, have a desktop Socket 1151 platform, and are constrained by the 16 PCIe Gen 3 lanes that Intel specifies. The data does not support a performance verdict based on the missing tests, but it does support a verdict based on efficiency: AMD achieves its results at 15W, while Intel requires 62W. For mobile use, the Ryzen is the only viable option in this pair; the Core i3-9320 is a desktop-only part.

Where Each One Wins

The AMD Ryzen 5 PRO 4650U wins in every head-to-head benchmark where data exists. In Cinebench R15 multi-core, it leads by 84.3%; in single-core, it leads by 98.9%. It also wins on efficiency, delivering those results at 15W versus 62W for the Intel chip. The Ryzen’s 6-core, 12-thread configuration, larger per-core L2 cache (512 KB versus 256 KB), and higher memory bandwidth (68.3 GB/s versus 38.4 GB/s) all point to advantages in heavily threaded applications and memory-bound tasks. It is the winner for mobile productivity, rendering, and any workload that can use more than 4 threads.

The Intel Core i3-9320 wins in areas that are not benchmark-related but are still factual from the data. It supports ECC memory, which the AMD part does not. It has a higher base clock (3.70 GHz versus 2.10 GHz) and a higher boost clock (4.40 GHz versus 4.00 GHz), which may benefit lightly threaded tasks that do not scale with core count — though the single-core benchmark contradicts this, with AMD winning by 98.9%. The Intel chip also has 16 PCIe Gen 3 lanes specified for the CPU, whereas AMD’s lane count is not listed. For desktop users with an existing Socket 1151 platform and a need for ECC, the Core i3-9320 is the logical choice, despite its lower raw scores in the shared tests.
