AMD Ryzen 5 PRO 8640U vs Intel Arc G3 Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the AMD Ryzen 5 PRO 8640U and the Intel Arc G3. The Intel Arc G3 has no recorded benchmark scores in the database, while the AMD Ryzen 5 PRO 8640U has a comprehensive set of 17 benchmark entries. The AMD part's average benchmark score sits at 30,254, placing it in the 81st percentile of all CPUs tracked. The Intel Arc G3, by contrast, has an average benchmark score of 0 and sits in the 50th percentile, a figure that reflects the absence of recorded data rather than actual performance.

The AMD Ryzen 5 PRO 8640U delivers a Cinebench R23 multi-core score of 19,982 and a single-core score of 2,821. In Cinebench R20, it records 8,392 multi-core and 1,184 single-core. The older Cinebench R15 run shows 2,014 multi-core and 284 single-core. PassMark results include a multithread score of 22,795 and a single-thread score of 3,732. Additional PassMark subtests show integer math at 74,875, floating point math at 45,265, extended instructions at 19,130, data compression at 260,925, data encryption at 15,843, find prime numbers at 78, physics at 1,154, and random string sorting at 32,114.

The nearest rivals to the AMD Ryzen 5 PRO 8640U, based on average score, are the AMD Ryzen 7 2700X at 30,213 (0.1% behind), the AMD Ryzen 7 7736U at 30,364 (0.4% ahead), the AMD Ryzen 5 7640HS at 30,390 (0.4% ahead), and the Intel Core i9-11980HK at 30,422 (0.6% ahead). The AMD Ryzen 5 PRO 8640U is effectively within a fraction of a percent of these processors in aggregate performance. The Intel Arc G3 has no nearest rivals listed, so a direct comparison of its measured output against any other part is not possible from the recorded data.

Architecture Differences

The AMD Ryzen 5 PRO 8640U uses the Zen 4 architecture under the Hawk Point codename, built on a 4 nm process at TSMC. It has 6 cores and 12 threads, with a base clock of 3.50 GHz and a boost clock of 4.90 GHz. The Intel Arc G3 uses the Panther Lake codename, built on a 3 nm process at Intel's own foundry. It has 14 cores and 14 threads, with a base clock of 1.90 GHz and a boost clock of 4.60 GHz. The Intel part has more than twice the core count but no simultaneous multithreading, while the AMD part uses SMT to reach 12 threads from 6 cores.

Cache layouts differ substantially. The AMD Ryzen 5 PRO 8640U has 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. The Intel Arc G3 has 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The Intel part has larger per-core cache allocations at every level and a larger shared L3 pool. The AMD part lists 25,000 million transistors on a 178 mm² die; the Intel Arc G3 has no transistor count or die size recorded in the database.

Memory support also diverges. The AMD Ryzen 5 PRO 8640U supports DDR5 on a dual-channel bus with 89.6 GB/s of bandwidth and ECC memory. The Intel Arc G3 supports LPDDR5X on a dual-channel bus with 136.5 GB/s of bandwidth and no ECC support. The Intel part has a 52% memory bandwidth advantage by the recorded figures. PCIe connectivity differs as well: the AMD part offers Gen 4 with 20 lanes (CPU only), while the Intel part offers Gen 5 with 4 lanes (CPU only). The Intel part uses a newer PCIe generation but far fewer lanes.

The integrated graphics are Radeon 760M on the AMD part and Arc B370 on the Intel part. The AMD Ryzen 5 PRO 8640U uses AMD Socket FP7, while the Intel Arc G3 uses Intel BGA 2540. Both are mobile-market parts with active production status. The AMD part launched on April 15, 2024; the Intel part has a release date of May 27, 2026. The AMD part's part numbers are 100-000001318 (FP7r2) and 100-000001378 (FP7); the Intel part's part number is SA4QZ. Neither part has a launch MSRP recorded, and neither has an unlocked multiplier.

Where Each One Wins

The AMD Ryzen 5 PRO 8640U wins in every measured category because it is the only one of the two with benchmark data. Its Cinebench R23 single-core score of 2,821 and multi-core score of 19,982 establish a baseline for a 6-core, 12-thread Zen 4 mobile processor. The PassMark single-thread result of 3,732 and multithread result of 22,795 indicate a balanced profile for both lightly threaded and heavily threaded workloads. The data compression score of 260,925 is by far the highest of its PassMark subtests, suggesting strong performance in compression-type workloads. Integer math at 74,875 and floating point math at 45,265 show a solid general-purpose compute capability.

The Intel Arc G3 has no recorded wins because no benchmark scores exist in the database. Its architectural specifications, however, point to areas where it could plausibly compete: 14 cores at 14 threads, a 3 nm process, and a memory bandwidth of 136.5 GB/s. The larger L3 cache of 18 MB and per-core L2 of 2.5 MB provide a structural advantage for workloads that benefit from larger cache footprints. The PCIe Gen 5 connection, while limited to 4 lanes, offers a newer interface for compatible devices. These are specifications, not measured results, and the database records no performance data to confirm or refute their impact.

The AMD part's advantage in the database is a matter of data availability. The Intel Arc G3's 0 average score and empty benchmark array mean that any comparison of wins is one-sided. The AMD Ryzen 5 PRO 8640U's 81st percentile standing among all CPUs places it above the median, while the Intel Arc G3's 50th percentile reflects its lack of recorded measurements rather than a computed performance level.

The Verdict

The data supports a clear split. For anyone selecting a processor with verified performance, the AMD Ryzen 5 PRO 8640U is the only option with measured results. It delivers an 81st percentile standing, with Cinebench R23 scores of 19,982 multi-core and 2,821 single-core, and aggregate PassMark scores of 22,795 multithread and 3,732 single-thread. Its nearest rivals, all within 0.6% in average score, include the AMD Ryzen 7 2700X, AMD Ryzen 7 7736U, AMD Ryzen 5 7640HS, and Intel Core i9-11980HK. That places it in familiar 6-core mobile territory with competitive aggregate performance.

The Intel Arc G3 is a specification-only entry in the database. With 14 cores, a 3 nm process, 136.5 GB/s of memory bandwidth, and 18 MB of L3 cache, its architecture suggests a different design philosophy: more physical cores, no SMT, larger caches, and a newer process node. But without any recorded benchmark scores, the database cannot confirm how those specifications translate into performance. The 50th percentile and 0 average score are placeholders, not measurements.

For a workload that depends on verified multi-threaded performance, the AMD Ryzen 5 PRO 8640U has the recorded data to support a choice. For a workload that might benefit from 14 physical cores or LPDDR5X memory bandwidth, the Intel Arc G3 presents an architectural argument, but the absence of measurements leaves that argument untested. The practical selection from the available data is the AMD part, because it has measurable results and a percentile ranking that reflects real performance. The Intel part's capabilities remain unquantified.
