AMD Ryzen 5 40 vs Intel Arc G3 Comparison

AMD Ryzen 5 40 and Intel Arc G3 represent two different approaches to mobile computing, separated by process technology, core count, and memory support. The recorded data places the Ryzen 5 40 in the 70th percentile among all CPUs, while the Arc G3 sits in the 50th percentile. The database shows no direct head-to-head benchmarks between these two processors, so the comparison relies on their individual benchmark records, architectural specifications, and aggregate scores.

Head-to-Head Benchmarks

The database contains no shared benchmark results for the AMD Ryzen 5 40 and the Intel Arc G3. The Arc G3 has an empty benchmark array, meaning no recorded scores exist for any test across the Cinebench or Passmark suites. The Ryzen 5 40, by contrast, has fifteen recorded benchmark scores spanning both Cinebench R15 and R23 versions, as well as the Passmark test suite.

Without direct comparisons, the nearest rival data for the Ryzen 5 40 provides context for its performance tier. The Ryzen 5 40 posts an average benchmark score of 15882, which places it within 0.4 percent of the AMD EPYC 9354P (15826), 0.1 percent ahead of the AMD EPYC 75F3 (15859), and 0.2 percent behind the Intel Core Ultra 5 134U (15910). The tight clustering of these scores indicates that the Ryzen 5 40 performs in a consistent band regardless of the rival processor. The largest delta among its nearest rivals is 0.4 percent, which is remarkably small and suggests the Ryzen 5 40 delivers stable, predictable performance across workloads.

Looking at the individual benchmark results for the Ryzen 5 40, the strongest showing appears in the Passmark data compression test, where it scores 141533. This result dwarfs its other Passmark scores, indicating a particular strength in compression workloads. The integer math score of 31598 and floating point math score of 15194 both sit in ranges consistent with a quad-core processor with simultaneous multithreading. The single-thread Passmark score of 2477 represents the processor's peak single-core capability, while the multithread score of 9341 shows the scaling benefit of its eight threads.

In Cinebench, the Ryzen 5 40 scores 4841 in the R23 multicore test and 1150 in the R23 single-core test. The R15 results follow a similar pattern: 790 for multicore and 165.5 for single-core. The ratio between multicore and single-core scores in R23 is 4.2x, which aligns with expectations for a processor with four physical cores and eight threads under heavy load. The R15 ratio is 4.8x, slightly higher, suggesting the shorter benchmark duration allows more sustained boost behavior.

Where Each One Wins

The AMD Ryzen 5 40 holds every recorded benchmark advantage because the Intel Arc G3 has no recorded benchmark scores in the database. This makes a direct win/loss split impossible to calculate from measured data. Instead, the specifications point to complementary strengths.

The Ryzen 5 40 uses a 6 nm process from TSMC, has four cores and eight threads, and runs at a base clock of 2.80 GHz with a boost clock of 4.30 GHz. Its 15 W thermal design power suits thin-and-light mobile systems where sustained performance matters more than peak throughput. The 4 MB shared L3 cache and 512 KB L2 per core provide adequate data locality for single-threaded applications. The Radeon 610M integrated graphics handles display output and basic acceleration without requiring a discrete GPU.

The Intel Arc G3 uses a 3 nm process from Intel, has 14 cores and 14 threads, and runs at a base clock of 1.90 GHz with a boost clock of 4.60 GHz. Its 25 W thermal design power is higher than the Ryzen 5 40, indicating the design prioritizes performance per watt at a higher absolute power draw. The 18 MB shared L3 cache and 2.5 MB L2 per core represent a substantially larger cache hierarchy, which benefits workloads with larger working sets. The Arc B370 integrated graphics and LPDDR5X memory support with 136.5 GB/s bandwidth suggest the Arc G3 is positioned for graphics-adjacent tasks.

For single-threaded responsiveness, the Arc G3's 4.60 GHz boost clock exceeds the Ryzen 5 40's 4.30 GHz by 0.30 GHz. For sustained multithreaded work, the Arc G3's 14 cores provide more parallel execution units, although the lack of simultaneous multithreading means its thread count equals its core count at 14. The Ryzen 5 40's eight threads from four cores with SMT could match or exceed the Arc G3 in lightly threaded workloads where clock speed and cache latency dominate.

Architecture Differences

The architectural gap between these two processors is substantial. The Ryzen 5 40 uses AMD's Zen 2 architecture on the Mendocino codename, fabricated on a 6 nm process at TSMC. The Intel Arc G3 uses the Panther Lake codename on a 3 nm process at Intel. The process node difference of 6 nm versus 3 nm represents two full generations of fabrication technology, which typically translates to differences in transistor density and power efficiency.

The core count disparity is the most visible architectural difference. The Ryzen 5 40 has four cores and eight threads, while the Arc G3 has 14 cores and 14 threads. The Ryzen 5 40 enables simultaneous multithreading, so each physical core can process two threads. The Arc G3 does not enable this feature, so its 14 cores process exactly 14 threads. This means the Ryzen 5 40 has a 1:2 core-to-thread ratio, while the Arc G3 has a 1:1 ratio.

Cache hierarchies differ on every level. The Ryzen 5 40 provides 64 KB of L1 cache per core, 512 KB of L2 per core, and 4 MB of shared L3. The Arc G3 provides 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The L3 cache difference is particularly notable: 4 MB versus 18 MB, a 4.5x gap. The per-core L2 difference is also large, with the Arc G3 offering 2.5 MB per core versus 512 KB per core on the Ryzen 5 40.

Memory support and bandwidth also diverge. The Ryzen 5 40 supports LPDDR5 across a dual-channel bus with 88.0 GB/s bandwidth. The Arc G3 supports LPDDR5X across a dual-channel bus with 136.5 GB/s bandwidth. The LPDDR5X standard offers higher data rates than LPDDR5, and the recorded bandwidth reflects that advantage. Neither processor supports ECC memory.

PCIe connectivity differs by generation and lane count. The Ryzen 5 40 uses PCIe Gen 3 with 4 lanes from the CPU. The Arc G3 uses PCIe Gen 5 with 4 lanes from the CPU. The Gen 5 interface provides double the bandwidth per lane compared to Gen 3, which matters for high-speed peripherals like NVMe storage or external GPU enclosures.

The integrated graphics also differ. The Ryzen 5 40 includes a Radeon 610M, while the Arc G3 includes an Arc B370. The Arc B370 is a newer generation Intel graphics solution, and paired with the faster LPDDR5X memory, it likely offers better graphics performance, though no benchmark data exists in the database to confirm this.

The Verdict

The database paints a clear picture for the AMD Ryzen 5 40: it has measurable, competitive benchmark scores. Its 15882 average benchmark score sits within 0.4 percent of server-class EPYC processors, and its 70th percentile placement among all CPUs indicates solid mid-range performance. The Cinebench R23 multicore score of 4841 and single-core score of 1150 give concrete reference points for productivity workloads. The Passmark data compression score of 141533 stands out as a particularly strong result, suggesting the Ryzen 5 40 handles compression and archiving tasks well.

The Intel Arc G3 presents a different situation. With no benchmark scores recorded, the database cannot confirm its real-world performance. What the specifications show is a processor with more cores, more cache, faster memory support, and a more advanced process node. The 14 cores and 18 MB L3 cache suggest strong multithreaded potential. The 136.5 GB/s memory bandwidth and PCIe Gen 5 support point to a platform designed for faster data movement. The 3 nm process at Intel indicates a modern fabrication approach that could deliver better power efficiency at higher clocks.

For users who need measured performance data, the Ryzen 5 40 is the only choice between these two with recorded benchmarks. Its 15 W TDP and 2.80 GHz base clock suit efficient mobile operation, and its 70th percentile ranking provides confidence in its capabilities. The Arc G3 remains an unproven quantity in the database, with specifications that promise strong performance but no scores to validate that promise.

For users who prioritize core count and cache capacity, the Arc G3 offers clear specification advantages. Its 14 cores, 18 MB L3 cache, and 4.60 GHz boost clock all exceed the Ryzen 5 40. The 50th percentile placement, while lower than the Ryzen 5 40's 70th percentile, reflects the absence of benchmark data rather than measured inferiority.

The selection between these processors hinges on data availability. The Ryzen 5 40 has verified performance records across multiple test suites. The Arc G3 has architectural advantages on paper but no empirical results. For applications where measured performance matters, the Ryzen 5 40 is the documented choice. For workloads that stress core count and cache capacity, the Arc G3's specifications make it the logical candidate, pending benchmark data to confirm its capabilities.
