AMD Ryzen 3 PRO 5355G vs Intel Arc G3 EXTREME Comparison

Where Each One Wins

The benchmark data presents a remarkably one-sided picture. The Intel Arc G3 EXTREME wins all 11 head-to-head benchmark comparisons recorded in the database, while the AMD Ryzen 3 PRO 5355G records zero wins. This is not a close contest in any measured category. The Intel part dominates across every workload type, from single-threaded operations to heavily parallel tasks.

The AMD Ryzen 3 PRO 5355G does not win a single recorded test. Its closest margin comes in integer math, where it trails by 35.5 percent. The Intel Arc G3 EXTREME's largest victory occurs in the prime number search test, where the AMD processor scores 36 against Intel's 248, a gap of 85.5 percent. This pattern suggests the Intel part is not merely faster in one niche but holds an advantage across fundamentally different instruction patterns.

For the AMD processor, its strongest relative showing appears in integer math and data compression, though both still fall behind by more than a third. The data indicates the Ryzen 3 PRO 5355G is competitive in workloads that favor traditional integer execution, but the Intel chip's architectural advantages overwhelm it elsewhere. The floating point math test shows Intel leading by 71 percent, and the physics test shows a 72.1 percent advantage, indicating the Intel part handles both scalar and vector workloads with significantly more throughput.

Architecture Differences

The two processors come from entirely different design philosophies. The AMD Ryzen 3 PRO 5355G uses the Zen 3 architecture on a 7 nm TSMC process, while the Intel Arc G3 EXTREME employs Intel's own 3 nm node with the Panther Lake codename. This process advantage likely explains much of the performance gap, as the Intel part fits more transistors into a smaller area with better power characteristics.

Core counts differ substantially. The AMD chip provides 4 cores and 8 threads, while the Intel part offers 14 cores and 14 threads. The Intel processor does not use simultaneous multithreading, which is why its thread count equals its core count. The AMD chip relies on SMT to reach 8 threads from 4 physical cores. The Intel part's 14 physical cores give it a raw parallelism advantage that shows in multithreaded tests.

Cache hierarchies diverge sharply. The AMD processor has 64 KB of L1 per core, 512 KB of L2 per core, and 8 MB of shared L3. The Intel part carries 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The Intel chip's larger per-core caches and more than double the L3 capacity feed its higher instruction throughput. The AMD chip's total cache is smaller in every category.

Memory architecture differs as well. The AMD processor supports DDR4 with dual-channel access and 51.2 GB/s bandwidth. The Intel part uses LPDDR5X with dual-channel access and 136.5 GB/s bandwidth, more than 2.5 times the memory bandwidth. The Intel part also supports PCIe Gen 5 with 4 lanes, while the AMD processor uses PCIe Gen 3 with 16 lanes. The AMD chip supports ECC memory, the Intel part does not. The Intel processor integrates Arc B390 graphics, while the AMD chip includes Radeon Vega 6.

The AMD part runs at 4.00 GHz base and 4.20 GHz boost with a 65 W TDP. The Intel chip has a 1.90 GHz base clock but boosts to 4.70 GHz, with a much lower 25 W TDP. The Intel part's higher boost clock combined with its process advantage explains its single-thread dominance. The AMD processor uses socket AM4, while the Intel part uses BGA 2540, indicating a mobile-focused design. The Intel chip's market segment is Mobile, while the AMD part targets Desktop.

Head-to-Head Benchmarks

The Intel Arc G3 EXTREME wins every recorded comparison, but the margins vary substantially by workload. The largest victory occurs in the prime number search, where Intel scores 248 against AMD's 36, a 85.5 percent difference. This test rewards the Intel part's higher boost clock and larger caches, which accelerate integer iteration loops.

Floating point math shows Intel at 86929 versus AMD at 25245, a 71 percent gap. The physics test follows closely with Intel at 2515 and AMD at 701, a 72.1 percent difference. These results indicate the Intel part's architecture handles mathematical and physics simulation workloads with far greater efficiency, likely due to its 3 nm process allowing higher sustained clocks.

The multithread test shows Intel at 30659 versus AMD's 14033, a 54.2 percent difference. These tests confirm that the Intel part's advantage extends beyond raw clock speed into instruction-level efficiency.

The narrowest margins appear in integer math, where Intel leads by 35.5 percent, and data compression, where Intel leads by 45.3 percent. Random string sorting shows a 49.6 percent gap. Single-thread performance shows Intel at 4293 versus AMD's 3096, a 27.9 percent difference, which is the smallest margin recorded. This suggests the AMD processor's Zen 3 cores remain competitive in lightly threaded integer work, but the Intel part's higher boost clock and larger caches still prevail.

The average benchmark score reflects this dominance. The Intel part averages 36699 across all recorded tests, while the AMD part averages 27382. The Intel chip sits at the 85th percentile of all CPUs, while the AMD chip sits at the 79th percentile.

The Verdict

The data leaves little room for ambiguity. The Intel Arc G3 EXTREME outperforms the AMD Ryzen 3 PRO 5355G in every recorded benchmark, with margins ranging from 27.9 percent in single-thread to 85.5 percent in prime number search. The Intel part's 14 physical cores, 18 MB of L3 cache, 136.5 GB/s memory bandwidth, and 4.70 GHz boost clock combine to deliver superior results across all workload types.

The AMD Ryzen 3 PRO 5355G does retain some advantages in the specification sheet. It supports ECC memory, which the Intel part does not. It uses the AM4 socket, which may offer more upgrade flexibility for desktop users. It has a lower boost clock but a much higher base clock, which could benefit sustained workloads that do not hit boost conditions. Its 65 W TDP is higher than the Intel part's 25 W, but for a desktop processor this is not necessarily a drawback.

For users prioritizing raw performance in every measured category, the Intel Arc G3 EXTREME is the clear choice based on benchmark results. For users who require ECC memory support or prefer a desktop socket design, the AMD Ryzen 3 PRO 5355G offers those specific features, though with a significant performance penalty. The percentile rankings reinforce this conclusion: the Intel part sits at the 85th percentile of all CPUs, while the AMD part sits at the 79th percentile, a gap of six percentile points that reflects the average benchmark score difference of 9317 points.
