AMD Ryzen 5 7500X3D vs Intel Arc G3 EXTREME Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive overall victory for the Intel Arc G3 EXTREME, which wins 10 of the 11 shared Passmark tests. The AMD Ryzen 5 7500X3D claims only a single win. The most dramatic difference appears in floating point math, where the Intel part scores 86,929 versus 43,594 for the AMD, a 49.9% advantage. This is the largest delta in the entire comparison and indicates a substantially stronger FPU pipeline or wider execution resources.

Data encryption also favors Intel heavily. The Arc G3 EXTREME scores 23,881, while the Ryzen 5 7500X3D manages 15,797, a 33.9% gap. This suggests more efficient cryptographic instruction handling or a higher sustained throughput for AES-type workloads. Extended instructions follow a similar pattern: Intel leads 24,017 to 20,455, a 14.8% difference, indicating better support for SIMD and specialized instruction sets.

Multithreaded performance shows a clear Intel lead. The Arc G3 EXTREME records 30,659 in Passmark multithread, while the Ryzen 5 7500X3D scores 25,047, an 18.3% deficit for the AMD part. This aligns with the core count difference, but the single-thread results tell a more nuanced story. Intel wins single-thread 4,293 to 3,494, an 18.6% margin. The same delta appears in the duplicated singlethread test, confirming consistency.

Integer math is nearly a tie. Intel scores 71,164 versus 70,774 for AMD, a mere 0.5% difference. This indicates that per-core integer throughput is comparable, and the overall multithread advantage comes from having more cores rather than faster cores. Random string sorting shows Intel ahead by 11.6% (37,331 vs 32,999), and data compression shows Intel leading by 11.5% (307,094 vs 271,649). Prime number finding favors Intel by 10.9% (248 vs 221).

The only AMD win is in physics simulation. The Ryzen 5 7500X3D scores 2,779 against Intel's 2,515, a 10.5% advantage. This is notable because physics tests often depend on cache latency and memory access patterns, areas where the AMD part's large L3 cache could compensate for its lower raw throughput elsewhere.

Overall average benchmark scores place the Ryzen 5 7500X3D at 44,573, ranking in the 89th percentile of all CPUs. The Intel Arc G3 EXTREME averages 36,699, ranking in the 85th percentile. Despite winning most head-to-head tests, the Intel part has a lower average score because its benchmark suite includes Cinebench results that are not directly comparable to the AMD's Passmark-centric data. The nearest rivals for the AMD part include the Intel Core Ultra X9 388H (delta 0.2%), Intel Core i9-13950HX (0.5%), AMD Ryzen AI Max 385 (0.6%), and Intel Core i5-14600 (-0.7%). For Intel, the closest competitors are Intel Core Ultra 5 225 (-0.6%), AMD Ryzen 5 5600F (-0.7%), AMD Ryzen 5 5500X3D (-0.9%), and AMD Ryzen AI 7 PRO 450 (-1.1%).

Architecture Differences

The two processors diverge fundamentally in design philosophy. The AMD Ryzen 5 7500X3D uses 6 cores and 12 threads, built on the Raphael codename with Zen 4 architecture. It is manufactured on a 5 nm process at TSMC, packing 11,270 million transistors into a 71 mm² die. The Intel Arc G3 EXTREME uses 14 cores and 14 threads, based on the Panther Lake codename with Arc G3 generation, fabricated on Intel's own 3 nm process. The database does not list transistor count or die size for the Intel part.

Cache organization differs substantially. The AMD chip provides 64 KB of L1 per core, 1 MB of L2 per core, and a massive 96 MB of shared L3 cache. The Intel part offers 192 KB of L1 per core, 2.5 MB of L2 per core, but only 18 MB of shared L3. This 78 MB difference in L3 capacity is the defining architectural distinction. The AMD part's larger cache likely explains its physics test win, since physics simulations often benefit from reduced memory latency on repeated data access.

Clock speeds also differ. The AMD processor has a 4.00 GHz base clock and 4.50 GHz boost clock. The Intel processor has a much lower 1.90 GHz base clock but a higher 4.70 GHz boost clock. The lower base clock suggests Intel relies on aggressive boosting under load, while the AMD part maintains a higher sustained baseline frequency.

Memory support separates the two clearly. AMD uses DDR5 with dual-channel configuration, delivering 83.2 GB/s bandwidth. Intel uses LPDDR5X with dual-channel configuration, achieving 136.5 GB/s, a 64% higher memory bandwidth figure. This could contribute to Intel's wins in data compression and random string sorting, which are memory-bandwidth-sensitive workloads.

PCIe connectivity differs in lane count. The AMD socket supports Gen 5 with 24 CPU lanes, while the Intel BGA package provides Gen 5 with only 4 CPU lanes. This makes the AMD part more suitable for systems with multiple high-speed expansion devices. The AMD chip also supports ECC memory, while the Intel part does not.

Integrated graphics differentiate the parts. AMD includes Radeon Graphics, while Intel integrates Arc B390 graphics. The database does not provide performance metrics for these iGPUs, so no comparative analysis is possible. The AMD part uses Socket AM5, indicating a desktop market segment, while the Intel part uses BGA 2540, indicating a mobile segment. The AMD part is listed with a launch MSRP of $269, while the Intel part has no recorded launch MSRP.

FAQ

The Verdict

The data indicates two distinct use cases. The AMD Ryzen 5 7500X3D is a desktop processor with 6 cores and 12 threads, using Socket AM5. Its 96 MB L3 cache and ECC support position it for workloads where large working sets fit in cache and data integrity matters. The physics benchmark win confirms this advantage in specific simulation scenarios. Its 89th percentile ranking and average score of 44,573 place it slightly ahead of rivals like the Intel Core Ultra X9 388H and Intel Core i9-13950HX.

The Intel Arc G3 EXTREME is a mobile processor with 14 cores and 14 threads, using BGA 2540. Its 3 nm process, higher boost clock, and 136.5 GB/s memory bandwidth deliver superior results in most computational tasks. The 49.9% lead in floating point math and 33.9% lead in encryption indicate strong number-crunching capabilities. Its 85th percentile ranking places it near the AMD Ryzen 5 5500X3D and Intel Core Ultra 5 225.

For users prioritizing cache-heavy workloads, physics simulation, or ECC memory, the AMD part is the clear choice. For general-purpose compute, especially floating point, encryption, and multithreaded tasks, the Intel part dominates. The Intel chip also consumes less power at 25 W TDP versus 65 W for AMD, making it more suitable for thermally constrained environments. The AMD part offers more PCIe lanes (24 vs 4) and a larger L3 cache, while the Intel part counters with more cores, higher bandwidth, and a more advanced process node. Neither part has an unlocked multiplier, so overclocking is not a differentiator.
