AMD Ryzen 5 PRO 8540U vs Intel Arc G3 EXTREME Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive overall advantage for the Intel Arc G3 EXTREME, which wins 15 of the 17 head-to-head benchmark comparisons. The AMD Ryzen 5 PRO 8540U claims only two victories, both in the Cinebench R23 suite. The average benchmark score for the Intel part is 36,699, placing it in the 85th percentile of all CPUs, while the AMD chip averages 23,709, good for the 76th percentile.

The largest single margin comes in PassMark floating point math, where the Intel Arc G3 EXTREME scores 86,929 versus 34,865 for the AMD Ryzen 5 PRO 8540U, a delta of 59.9 percent. The physics workload shows a similar gap: Intel scores 2,515 against AMD's 983, a 60.9 percent deficit. Prime number finding is even more lopsided in relative terms, with Intel at 248 and AMD at 66, a 73.4 percent difference. These three workloads point to a substantial advantage in mathematical throughput and physics simulation for the Intel processor.

The PassMark multithread test shows Intel at 30,659 versus AMD at 18,218, a 40.6 percent gap. Data encryption follows the same pattern: Intel scores 23,881, AMD scores 12,319, a 48.4 percent delta. Extended instructions favor Intel at 24,017 against 15,410, a 35.8 percent margin. Integer math is closer but still favors Intel, with 71,164 versus 56,738, a 20.3 percent advantage. Random string sorting shows Intel ahead at 37,331 versus 24,797, a 33.6 percent lead. Data compression lands at 307,094 for Intel and 205,703 for AMD, a 33 percent delta.

In the Cinebench R20 suite, Intel dominates both tests. The multicore result is 10,945 against 6,491, a 40.7 percent gap. The singlecore result is 1,545 versus 916, also a 40.7 percent delta. Cinebench R15 shows Intel ahead in multicore at 2,192 versus 1,557, a 29 percent margin, and in singlecore at 267 versus 219, an 18 percent lead.

The AMD Ryzen 5 PRO 8540U wins the Cinebench R23 multicore test with 15,456 points against Intel's 14,655, a 5.5 percent margin. The AMD chip also takes R23 singlecore with 2,182 versus 1,862, a 17.2 percent advantage. These two results are notable because they run opposite to the pattern seen in R15 and R20, where Intel leads by large margins. The R23 results suggest the AMD architecture scales better in that specific workload version, despite losing decisively in the older Cinebench releases.

PassMark single-thread testing shows Intel at 4,293 versus AMD at 3,563, a 17 percent delta. The duplicate listing for this test confirms the same score on both entries.

Where Each One Wins

The Intel Arc G3 EXTREME wins in every PassMark category and in Cinebench R15 and R20, both multicore and singlecore. Its largest edges appear in floating point math, physics, and prime number finding, where the deltas range from 59.9 to 73.4 percent. The PassMark multithread score of 30,659 indicates strong parallel throughput, and the data encryption result of 23,881 shows a major advantage in cryptographic workloads. For users running compression, encryption, extended instruction sets, sorting algorithms, or integer-heavy tasks, the recorded data consistently places Intel ahead by margins from 20.3 to 48.4 percent.

The AMD Ryzen 5 PRO 8540U wins specifically in Cinebench R23. The multicore score of 15,456 beats Intel's 14,655 by 5.5 percent, and the singlecore score of 2,182 beats Intel's 1,862 by 17.2 percent. These wins are isolated to the R23 version of the Cinebench workload. The AMD chip does not claim a single PassMark victory, and it loses both R15 and R20 tests by substantial margins. The data suggests that the AMD part performs better in the R23 rendering workload than in earlier Cinebench versions, but this advantage does not carry over to any other tested application.

The overall win count is 15 for Intel and 2 for AMD. The average score comparison reinforces this split: Intel at 36,699 sits 54.8 percent above AMD's 23,709. The percentile ranking also differs, with Intel at 85 versus AMD at 76.

Architecture Differences

The AMD Ryzen 5 PRO 8540U uses a 6-core, 12-thread configuration built on the Zen 4 architecture with the Hawk Point codename. It is manufactured on a 4 nm process at TSMC with 20,900 million transistors on a 137 mm² die. The Intel Arc G3 EXTREME uses 14 cores and 14 threads on a 3 nm process at Intel with the Panther Lake codename. The Intel part has no listed transistor count or die size in the database.

Cache layouts differ significantly. The AMD chip provides 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. The Intel chip provides 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The Intel part carries more cache at every level, which likely contributes to its PassMark advantages in data-heavy workloads.

Clock speeds show the AMD part with a base of 3.20 GHz and a boost of 4.90 GHz, while Intel runs at 1.90 GHz base and 4.70 GHz boost. The AMD chip has a higher boost clock, yet Intel still wins most single-thread tests. The Intel part compensates with a different core count and cache structure. The AMD processor draws 28 W TDP, while the Intel processor draws 25 W TDP.

Memory support differs as well. The AMD chip uses DDR5 with dual-channel access and 89.6 GB/s bandwidth, and it supports ECC memory. The Intel chip uses LPDDR5X with dual-channel access and 136.5 GB/s bandwidth, with no ECC support. The Intel memory bandwidth is 52.3 percent higher than AMD's, which helps explain the Intel advantage in memory-sensitive workloads like data compression and random string sorting.

PCIe connectivity also differs. The AMD part offers Gen 4 with 14 lanes from the CPU, while the Intel part offers Gen 5 with 4 lanes from the CPU. The Intel part uses the BGA 2540 socket, while AMD uses the FP7 socket. Integrated graphics differ too: AMD includes Radeon 740M, while Intel includes Arc B390.

The release dates are separated by more than two years. AMD launched on 2024-04-15, while Intel launches on 2026-05-27. Both parts are marked as Active in production status, and neither has an unlocked multiplier. The AMD part numbers are 100-000001329 (FP7r2) and 100-000001331 (FP7), while Intel uses SA4R3.

The Verdict

The data shows that the Intel Arc G3 EXTREME is the stronger performer across nearly every recorded benchmark. Its 15 wins out of 17 comparisons include all PassMark tests and both Cinebench R15 and R20 suites. The average benchmark score of 36,699 places it at the 85th percentile, and its nearest rivals include the Intel Core Ultra 5 225 at 36,938, the AMD Ryzen 5 5600F at 36,945, and the AMD Ryzen 5 5500X3D at 37,018, all within 1.1 percent. The Intel part sits 54.8 percent above the AMD Ryzen 5 PRO 8540U in average score.

The AMD Ryzen 5 PRO 8540U should be considered for workloads where Cinebench R23 performance matters most, particularly singlecore rendering. Its R23 singlecore score of 2,182 beats Intel by 17.2 percent, and its R23 multicore score of 15,456 beats Intel by 5.5 percent. The AMD chip also carries ECC memory support, which Intel lacks. However, the AMD part loses every other comparison, including all PassMark tests where the deltas range from 17 to 73.4 percent.

The Intel part offers 14 cores versus 6, more cache at every level, higher memory bandwidth, and a smaller process node. It also has a lower TDP of 25 W versus 28 W. The Intel chip wins in physics, floating point math, encryption, compression, and multithread throughput, making it the better choice for general productivity, mathematical computation, and data processing. The AMD chip wins only in R23, making it a specialized option for that specific rendering workload.

The percentile data reinforces the verdict. Intel sits at 85, AMD at 76. The nearest rivals for Intel include AMD Ryzen AI 7 PRO 450 at 37,093 with a delta of -1.1 percent, meaning Intel slightly trails that part. The nearest rival for AMD is the Intel Core i5-11500 at 23,718 with a delta of 0 percent, meaning the AMD chip performs essentially on par with that older Intel desktop processor.
