The Verdict

The data shows two processors aimed at different priorities within the mobile segment. The Intel Arc G3 EXTREME delivers substantially higher multi-threaded performance, evidenced by its 85th percentile ranking and an average benchmark score of 36699. The AMD Ryzen Embedded 8640U, with no recorded benchmark scores and a 50th percentile placement, cannot be directly compared on raw performance measurements in the database.

For workloads that depend on multi-core throughput, the Intel part is the clear choice based on its Cinebench and PassMark results. The chip's 14 cores and 14 threads, combined with a 3 nm process and 18 MB of shared L3 cache, produce strong scores across rendering and math-heavy tasks.

The AMD Ryzen Embedded 8640U targets embedded applications that require ECC memory support, a feature the Intel chip lacks. Its Zen 4 architecture, 6 cores and 12 threads, and 4 nm process from TSMC make it a lower-power option with a 28 W TDP compared to the Intel part's 25 W TDP.

The Intel Arc G3 EXTREME also brings newer platform features, including PCIe Gen 5 with 4 lanes and higher memory bandwidth at 136.5 GB/s. The AMD part uses PCIe Gen 4 with 20 lanes and 89.6 GB/s bandwidth.

Users needing maximum CPU performance in a mobile form factor should select the Intel Arc G3 EXTREME. Users requiring ECC memory and a smaller footprint for embedded systems should consider the AMD Ryzen Embedded 8640U.

Head-to-Head Benchmarks

The database contains benchmark results only for the Intel Arc G3 EXTREME, with no corresponding scores for the AMD Ryzen Embedded 8640U. Therefore, all performance analysis relies on the Intel chip's recorded measurements.

In Cinebench R15 multi-core, the Intel Arc G3 EXTREME scores 2192 points. Its single-core score in the same test is 267 points. Moving to Cinebench R20, the chip delivers 10945 points multi-core and 1545 points single-core. Cinebench R23 results show 14655 points multi-core and 1862 points single-core.

PassMark results for the Intel chip cover multiple workloads. Data compression scores 307094, while data encryption reaches 23881. Extended instructions score 24017, and prime number finding scores 248. Floating point math delivers 86929 points, and integer math scores 71164. The multithread test shows 30659 points, with physics at 2515 points. Random string sorting scores 37331, and single-thread performance measures 4293 points.

The Intel chip's nearest rivals in the database are the Intel Core Ultra 5 225 with an average score of 36938, the AMD Ryzen 5 5600F at 36945, the AMD Ryzen 5 5500X3D at 37018, and the AMD Ryzen AI 7 PRO 450 at 37093. The Intel Arc G3 EXTREME trails the Core Ultra 5 225 by 0.6%, the Ryzen 5 5600F by 0.7%, the Ryzen 5 5500X3D by 0.9%, and the Ryzen AI 7 PRO 450 by 1.1%. These deltas indicate the Arc G3 EXTREME performs within a narrow band of these established desktop and mobile processors.

Because the AMD Ryzen Embedded 8640U has zero recorded benchmarks, no head-to-head win analysis can be performed between the two items. The Intel part's scores stand alone as the only quantitative performance data in this comparison.

Specification Differences

The AMD Ryzen Embedded 8640U and Intel Arc G3 EXTREME differ across nearly every core specification field.

Core and thread counts: AMD has 6 cores and 12 threads; Intel has 14 cores and 14 threads.

Clock speeds: AMD starts at 3.50 GHz base and reaches 4.90 GHz boost. Intel starts at 1.90 GHz base and reaches 4.70 GHz boost.

Thermal design power: AMD is rated at 28 W; Intel at 25 W.

Socket: AMD uses AMD Socket FP8; Intel uses Intel BGA 2540.

Process node: AMD uses 4 nm from TSMC; Intel uses 3 nm from Intel's own foundry.

Architecture Differences

The AMD Ryzen Embedded 8640U uses Zen 4 architecture under the codename Hawk Point, belonging to the Ryzen Embedded generation. The Intel Arc G3 EXTREME uses Panther Lake as its codename, under the Arc G3 generation.

The transistor counts and die sizes differ significantly. AMD lists 25,000 million transistors on a 178 mm² die. Intel does not provide transistor count or die size data in the database.

Manufacturing approaches diverge: AMD relies on TSMC's 4 nm process, while Intel fabricates its chip on a 3 nm process at its own foundry. This gives Intel a denser process node, though the database does not include die size or transistor data for the Intel part to quantify the difference.

Cache architecture follows different designs. AMD distributes 64 KB L1 and 1 MB L2 per core, with 16 MB L3 shared across all cores. Intel allocates 192 KB L1 and 2.5 MB L2 per core, with 18 MB L3 shared. The larger per-core L1 and L2 allocations on the Intel chip suggest a design favoring higher per-thread cache residency.

Memory controllers differ in type and bandwidth. AMD pairs with DDR5 and achieves 89.6 GB/s. Intel pairs with LPDDR5X and reaches 136.5 GB/s, a 52% higher bandwidth figure. This difference likely benefits the Intel chip in memory-intensive workloads.

PCIe connectivity presents a trade-off. AMD provides Gen 4 with 20 lanes, which supports more simultaneous devices. Intel provides Gen 5 with 4 lanes, which offers higher per-lane bandwidth but fewer total lanes. The database records these as CPU-only lane counts.

ECC memory support separates the two. AMD enables ECC, a critical feature for embedded and reliability-focused applications. Intel omits ECC entirely.

Integrated graphics also differ: AMD ships Radeon 760M, while Intel ships Arc B390. The database does not include graphics benchmarks for either chip.

Where Each One Wins

The Intel Arc G3 EXTREME wins on raw computing performance in every measured category, based on the recorded benchmarks. Its 14 cores and 14 threads deliver multi-core scores that place it at the 85th percentile of all CPUs. The Cinebench R23 multi-core score of 14655 and PassMark multithread score of 30659 confirm strong parallel processing capability. The chip also leads in memory bandwidth at 136.5 GB/s and uses a newer 3 nm process.

The AMD Ryzen Embedded 8640U wins on features that matter for embedded deployments. It supports ECC memory, which the Intel chip does not. It offers 20 PCIe Gen 4 lanes versus 4 Gen 5 lanes on Intel, making it more suitable for systems needing many connected devices. Its 6 cores and 12 threads consume a 28 W TDP, slightly above Intel's 25 W but with a simpler core layout.

The Intel chip also leads in single-core performance where measured: 1862 points in Cinebench R23 single-core and 4293 in PassMark single-thread. The AMD chip has no recorded single-core scores, so no direct comparison exists.

For workloads like video rendering, data compression, and floating-point math, the Intel Arc G3 EXTREME shows clear strength. Its PassMark data compression score of 307094 and floating point math score of 86929 indicate strong throughput in these areas.

For embedded control systems, industrial computing, or applications requiring error-corrected memory, the AMD Ryzen Embedded 8640U presents the only viable option between the two, given its ECC support and broader PCIe lane count. The Intel chip cannot match these specific embedded requirements despite its performance advantages.

The database records no head-to-head benchmark results between the two processors, and the AMD chip has zero benchmark scores. Therefore, the quantitative performance comparison rests entirely on the Intel part's measurements and its percentile position relative to other CPUs in the database.
