AMD Ryzen 5 40 vs Intel Arc G3 EXTREME Comparison

The AMD Ryzen 5 40 and the Intel Arc G3 EXTREME occupy different corners of the mobile processor market, and their benchmark results reflect a fundamental performance gap. The recorded data shows the Intel part winning every single head-to-head comparison, with the AMD chip trailing by margins that range from 38% to nearly 92%. The Intel Arc G3 EXTREME posts an average benchmark score of 36,699, placing it in the 85th percentile of all CPUs, while the AMD Ryzen 5 40 averages 15,882, sitting in the 70th percentile. This is not a close contest; it is a clear hierarchy defined by silicon generation, core count, and memory bandwidth.

Head-to-Head Benchmarks

The Intel Arc G3 EXTREME dominates the AMD Ryzen 5 40 across every measured workload, but the size of the victory varies significantly by task type. The largest single margin appears in the PassMark find prime numbers test, where Intel scores 248 against AMD's 20, a 91.9% deficit for the AMD chip. This result indicates a massive advantage in integer-heavy, latency-sensitive computation, likely stemming from the Intel part's higher boost clock and larger per-core cache allocation.

In floating-point math, the Intel Arc G3 EXTREME records 86,929 points versus 15,194 for the Ryzen 5 40, a 82.5% gap. Physics simulation shows a similar pattern: Intel scores 2,515, AMD scores 432, an 82.8% difference. These two results suggest the Intel processor is substantially better at sustained scientific and simulation workloads, which rely heavily on vectorized instruction throughput and memory bandwidth. The Intel part's 136.5 GB/s memory bandwidth, nearly 55% higher than AMD's 88.0 GB/s, likely contributes to these outsized wins.

Multi-threaded Cinebench results reinforce the theme. In Cinebench R23 multicore, Intel scores 14,655 versus 4,841 for AMD, a 67% lead. The older Cinebench R15 multicore test shows Intel at 2,192 and AMD at 790, a 64% margin. These are the headline numbers for productivity users, and they clearly favor the Intel processor. The Intel part's 14 cores and 14 threads outnumber the AMD chip's 4 cores and 8 threads, which explains the breadth of the multi-core advantage.

Single-thread performance is closer, though still decisively Intel's. In Cinebench R23 single-core, Intel scores 1,862 against AMD's 1,150, a 38.2% lead. Cinebench R15 single-core shows Intel at 267 and AMD at 165.5, a 38% gap. PassMark single-thread results follow suit: Intel at 4,293, AMD at 2,477, a 42.3% difference. The Intel boost clock of 4.70 GHz versus AMD's 4.30 GHz helps, but the larger per-core L1 and L2 caches on the Intel part (192 KB and 2.5 MB per core versus 64 KB and 512 KB per core) are the more likely drivers of the single-thread edge.

Data-centric workloads show consistent Intel superiority, though with smaller margins than the math-heavy tests. PassMark data compression gives Intel 307,094 and AMD 141,533, a 53.9% lead. Integer math shows Intel at 71,164 and AMD at 31,598, a 55.6% margin. Data encryption is more lopsided: Intel scores 23,881, AMD scores 6,646, a 72.2% gap. Extended instruction sets (typically AVX and similar) favor Intel by 73.2%, with scores of 24,017 and 6,437. Random string sorting, a memory-latency-sensitive test, shows Intel at 37,331 and AMD at 15,124, a 59.5% margin.

The PassMark multithread and single-thread aggregate scores summarize the overall position. Intel's multithread score of 30,659 is 69.5% higher than AMD's 9,341. The single-thread aggregate of 4,293 versus 2,477 is a 42.3% gap. The average benchmark score difference, 36,699 versus 15,882, places the Intel chip 57% higher in overall performance. No workload in the database shows the AMD Ryzen 5 40 ahead, and the win count stands at 15 for Intel and 0 for AMD.

Architecture Differences

The two processors represent distinct architectural approaches separated by several hardware generations. The AMD Ryzen 5 40 uses the Zen 2 architecture under the Mendocino codename, fabricated on a 6 nm process at TSMC. It integrates 4 cores and 8 threads, with a base clock of 2.80 GHz and a boost clock of 4.30 GHz. The chip has a 100 mm² die size and a thermal design power of 15 watts. Its cache hierarchy includes 64 KB of L1 per core, 512 KB of L2 per core, and 4 MB of shared L3 cache. The integrated graphics is a Radeon 610M, and the memory interface is LPDDR5 over a dual-channel bus at 88.0 GB/s. PCIe connectivity is Gen 3 with 4 CPU lanes.

The Intel Arc G3 EXTREME uses the Panther Lake codename, fabricated on a 3 nm process at Intel's own foundry. It contains 14 cores and 14 threads, with a base clock of 1.90 GHz and a boost clock of 4.70 GHz. The thermal design power is 25 watts. The cache design is more generous: 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3 cache. The integrated graphics is an Arc B390, and memory support is LPDDR5X over a dual-channel bus at 136.5 GB/s. PCIe connectivity is Gen 5 with 4 CPU lanes.

These architectural differences explain the benchmark results. The Intel part has 3.5 times more cores and 75% more L3 cache. The per-core L1 cache is 3 times larger, and the per-core L2 cache is nearly 5 times larger. The higher boost clock of 4.70 GHz versus 4.30 GHz gives Intel an edge in single-thread tasks. The memory bandwidth advantage, 136.5 GB/s versus 88.0 GB/s, benefits every workload that streams data. The process node difference, 3 nm versus 6 nm, allows Intel to pack more transistors and run at higher clocks within a modest 25 watt envelope.

The AMD chip's lower 15 watt TDP and smaller 100 mm² die suggest a focus on efficiency and compact systems, while the Intel chip's higher 25 watt TDP and larger core count target performance-oriented mobile designs. Neither processor supports ECC memory, and both have locked multipliers. The AMD part uses AMD Socket FT6, while the Intel part uses Intel BGA 2540, meaning they are not socket-compatible. The Intel part has a part number SA4R3, while the AMD part's part number is listed as unknown.

The Verdict

The benchmark data indicates that the Intel Arc G3 EXTREME is the superior processor for every workload recorded in the database. Its 15-0 win record, combined with an average benchmark score of 36,699 versus 15,882, places it in a different performance class. The Intel part leads by 67% in Cinebench R23 multicore, by 38.2% in Cinebench R23 single-core, and by margins exceeding 80% in floating-point math, physics simulation, and extended instruction tests. It also holds a 72.2% advantage in data encryption and a 53.9% lead in data compression, making it the better choice for content creation, scientific computing, and data processing tasks.

The AMD Ryzen 5 40, however, has its own positioning. Its 15 watt TDP is 40% lower than the Intel chip's 25 watt TDP, which may translate into longer battery life and quieter cooling in thin-and-light laptops. The 6 nm process node and 100 mm² die size indicate a compact, power-efficient design. Its 4-core, 8-thread configuration and 4 MB L3 cache are modest, but the 2.80 GHz base clock is higher than the Intel part's 1.90 GHz, which could benefit idle and light-load scenarios.

The selection between these two processors depends on the intended use case, strictly from the data. For users who prioritize multi-threaded throughput, single-thread responsiveness, memory bandwidth, or integrated graphics capability, the Intel Arc G3 EXTREME is the clear choice. Its 85th percentile ranking versus the AMD chip's 70th percentile confirms the performance hierarchy. For users who require the lowest power consumption and a smaller physical footprint, the AMD Ryzen 5 40 offers a viable, if significantly less performant, alternative. The database shows no scenario where the AMD chip wins, so any decision favoring it must be based on power efficiency rather than raw benchmark results.
