The recorded data shows a clear overall winner in raw benchmark performance: the Intel Arc G3 EXTREME takes 15 of the 17 head-to-head benchmark comparisons, while the AMD Ryzen 5 8500G wins only 2. However, the nature of those victories reveals a nuanced picture. The Intel chip dominates in most compute-heavy and multi-threaded workloads, while the AMD chip shows surprising strength in specific newer rendering tests. The Intel Arc G3 EXTREME also holds a higher position in the overall performance percentile, ranking in the 85th percentile of all CPUs compared to the AMD chip's 74th percentile. This page analyzes the benchmark data, architectural differences, and the specific workloads where each processor delivers its best results.

Head-to-Head Benchmarks

The Intel Arc G3 EXTREME establishes its dominance across the PassMark suite. In floating point math, the Intel chip scores 86929 against the AMD chip's 39074, a 55.1% advantage. The gap in prime number finding is even larger: Intel scores 248 versus AMD's 87, a 64.9% lead. Physics calculations also favor Intel heavily, with a score of 2515 compared to 1318, a 47.6% difference. Data encryption shows Intel ahead by 40.5% (23881 versus 14220), and extended instructions see Intel leading by 20.5% (24017 versus 19098). Integer math is closer, with Intel at 71164 versus AMD's 63123, an 11.3% edge. Data compression favors Intel at 307094 versus 250197, an 18.5% margin. Random string sorting goes to Intel at 37331 versus 29407, a 21.2% difference. The PassMark multithread score confirms the trend: Intel at 30659 versus AMD's 21610, a 29.5% lead.

The Cinebench results present a more complex story. In the older Cinebench R15 and R20 tests, Intel wins all four comparisons. The R15 multicore test shows Intel at 2192 versus AMD's 1851, a 15.6% lead. R15 singlecore is close, Intel at 267 versus 261, only 2.2% ahead. The R20 tests show a larger Intel advantage: multicore at 10945 versus 7714 and singlecore at 1545 versus 1089, both representing 29.5% leads. However, the newer Cinebench R23 tests flip the result. The AMD Ryzen 5 8500G wins R23 multicore with a score of 18368 against Intel's 14655, a 25.3% lead. The R23 singlecore test shows AMD ahead by 39.3%, scoring 2593 versus Intel's 1862. This reversal suggests that the AMD chip's architecture handles the R23 workload more efficiently despite losing in the older tests.

The single-thread scores also favor Intel in the PassMark suite. The PassMark single thread test shows Intel at 4293 versus AMD's 3891, a 9.4% lead. This aligns with the R15 and R20 singlecore results, where Intel also wins, though the R23 singlecore result contradicts this pattern with a substantial AMD victory. The overall average benchmark score reinforces Intel's position: the Arc G3 EXTREME averages 36699 across its recorded benchmarks, while the Ryzen 5 8500G averages 20425. The Intel chip's nearest rivals in the database include the Intel Core Ultra 5 225 (average score 36938, a 0.6% difference), the AMD Ryzen 5 5600F (36945, 0.7% difference), and the AMD Ryzen 5 5500X3D (37018, 0.9% difference). The AMD Ryzen 5 8500G's nearest rivals include the AMD EPYC 9454P (20422, a 0% difference), the Intel Core Ultra 7 258V (20454, 0.1% difference), and the AMD Ryzen 5 5600 (20468, 0.2% difference). These rival comparisons place the Intel chip in a higher performance tier entirely.

Architecture Differences

The two processors use fundamentally different designs. The AMD Ryzen 5 8500G is built on the Zen 4 architecture with the codename Phoenix2, manufactured on a 4 nm process by TSMC. It contains 20,900 million transistors on a die size of 137 mm². The Intel Arc G3 EXTREME uses the Panther Lake codename, built on a 3 nm process at Intel's own foundry. The database does not record transistor count or die size for the Intel chip.

Core configuration differs sharply. The AMD chip has 6 cores and 12 threads, meaning each core supports two threads. The Intel chip has 14 cores and 14 threads, with no simultaneous multithreading. This gives Intel more physical cores but AMD more total threads. Cache layouts also differ. The AMD chip provides 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of shared L3 cache. The Intel chip provides 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3 cache. The Intel chip therefore has more cache at every level.

Clock speeds and power draw follow opposite patterns. The AMD chip has a base clock of 3.50 GHz and a boost clock of 5.00 GHz, with a 65 W TDP. The Intel chip has a base clock of 1.90 GHz and a boost clock of 4.70 GHz, with a much lower 25 W TDP. Despite the lower clocks and lower power envelope, the Intel chip generally outperforms the AMD chip in the recorded benchmarks.

Memory support also differs. The AMD chip uses DDR5 memory with dual-channel support and a recorded memory bandwidth of 83.2 GB/s. It supports ECC memory. The Intel chip uses LPDDR5X memory with dual-channel support and a higher memory bandwidth of 136.5 GB/s. It does not support ECC memory. The PCIe interface differs as well: AMD provides Gen 4 with 14 lanes (CPU only), while Intel provides Gen 5 with 4 lanes (CPU only).

Integrated graphics differ between the two. The AMD chip includes a Radeon 740M iGPU, while the Intel chip includes an Arc B390 iGPU. Both processors are classified as mobile market segment parts. The AMD chip uses the AMD Socket AM5, while the Intel chip uses the Intel BGA 2540 socket. Neither processor has an unlocked multiplier. The AMD chip has a launch MSRP of $179 and a release date of January 7, 2024. The Intel chip has no recorded launch MSRP and a release date of May 27, 2026.

The Verdict

The benchmark data supports a clear conclusion: the Intel Arc G3 EXTREME is the stronger processor for the majority of tested workloads. It wins 15 of 17 head-to-head comparisons, holds a higher average benchmark score (36699 versus 20425), and ranks in the 85th percentile of all CPUs versus the AMD chip's 74th percentile. The Intel chip delivers these results with a 25 W TDP compared to the AMD chip's 65 W TDP, making it the more efficient option in the recorded data. Its 14 physical cores and higher cache capacities at every level contribute to its broad advantage in PassMark tests, including a 55.1% lead in floating point math and a 64.9% lead in prime number finding.

The AMD Ryzen 5 8500G is not without merit. Its wins in the Cinebench R23 tests are substantial, particularly the 39.3% singlecore lead. The AMD chip also supports ECC memory, which the Intel chip does not, and it uses a socketed AM5 platform rather than a soldered BGA package. For users prioritizing the R23 rendering workload specifically, or those requiring ECC support, the AMD chip has a defined role. However, the overall data indicates that the Intel Arc G3 EXTREME offers superior performance across a wider range of applications, with a lower power draw and a higher memory bandwidth. The Intel chip represents the better choice for general-purpose and compute-intensive workloads based on the recorded measurements.

Where Each One Wins

The Intel Arc G3 EXTREME wins in every PassMark category recorded in the head-to-head data, including data compression, data encryption, extended instructions, find prime numbers, floating point math, integer math, multithread, physics, random string sorting, and single thread. Its largest margins come in prime number finding (64.9% ahead), floating point math (55.1% ahead), and physics (47.6% ahead). These results indicate a strong fit for scientific computing, financial modeling, encryption workloads, and any application that relies heavily on floating point operations. The Intel chip also wins the older Cinebench R15 and R20 tests in both singlecore and multicore, covering a broad range of rendering scenarios. Its higher memory bandwidth of 136.5 GB/s and larger cache pools support these compute-heavy tasks.

The AMD Ryzen 5 8500G wins the Cinebench R23 multicore and singlecore tests. The multicore margin is 25.3% and the singlecore margin is 39.3%. These are the only two head-to-head wins for the AMD chip, but they are significant in magnitude. The R23 results suggest the AMD chip has an architectural advantage in this specific rendering workload, potentially related to its higher boost clock of 5.00 GHz compared to Intel's 4.70 GHz. The AMD chip also offers ECC memory support, which is absent on the Intel chip, and a socketed AM5 platform. Users running Cinebench R23 as their primary benchmark, or those who require ECC memory for data integrity, would find the AMD processor preferable. For all other recorded workloads, the Intel Arc G3 EXTREME delivers higher scores, making it the dominant choice in the database's measurements.
