Architecture Differences

The AMD Ryzen 7 PRO 8840HS uses the Zen 4 architecture under the Hawk Point codename, built on a 4 nm process at TSMC. The Intel Arc G3 EXTREME uses the Panther Lake codename with an Intel 3 nm process. The AMD part integrates 25,000 million transistors on a 178 mm² die, while the database does not list transistor count or die size for the Intel part.

Core counts differ substantially. The AMD processor has 8 cores and 16 threads, while the Intel processor has 14 cores and 14 threads. This indicates the Intel part does not use simultaneous multithreading, whereas the AMD part doubles its thread count. Cache hierarchies also diverge. The AMD part provides 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. The Intel part provides 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The Intel design thus carries larger per-core caches at every level and slightly more shared L3.

The integrated graphics differ as well. The AMD Ryzen 7 PRO 8840HS pairs with a Radeon 780M, while the Intel Arc G3 EXTREME pairs with an Arc B390. The AMD processor uses AMD Socket FP7 and supports PCIe Gen 4 with 20 CPU lanes. The Intel processor uses Intel BGA 2540 and supports PCIe Gen 5 with 4 CPU lanes. Memory support also diverges: AMD uses dual-channel DDR5, while Intel uses dual-channel LPDDR5X with a higher bandwidth rating.

The Intel part shows a lower base clock of 1.90 GHz versus 3.30 GHz for the AMD part, but the boost clocks are closer at 4.70 GHz and 5.10 GHz respectively. The AMD part has a higher TDP of 28 watts versus 25 watts for the Intel part. Both are mobile processors with active production status, and neither has an unlocked multiplier. Release dates differ, with the AMD part appearing earlier in the database.

Head-to-Head Benchmarks

The head-to-head data shows a split with distinct strengths. The AMD Ryzen 7 PRO 8840HS takes the Cinebench R15 multi-core test decisively, scoring 2458 against 2192, a 12.1% margin. That is the largest multi-core win for AMD in the Cinebench suite. In Cinebench R23 multi-core, the gap shrinks dramatically: 14784 versus 14655, only 0.9% apart. The AMD part also wins Cinebench R15 single-core, but barely, at 271.5 versus 267, a 1.7% edge.

The Intel Arc G3 EXTREME strikes back in Cinebench R23 single-core, where it scores 1862 versus 1724, a 7.4% lead. This reverses the single-core picture from the older R15 benchmark. In PassMark single-thread, the Intel part extends its lead to 4293 versus 3692, a 14% advantage.

PassMark integer math strongly favors AMD, with 93342 versus 71164, a 31.2% lead. This is the largest AMD win in the entire head-to-head set. Data compression also goes to AMD, though narrowly: 311199 versus 307094, a 1.3% margin. Random string sorting goes to AMD with 37922 versus 37331, a 1.6% edge.

The Intel part wins the remaining PassMark tests by varying margins. Floating-point math shows a 35.9% lead for Intel, with 86929 versus 55739. Physics shows a 46.3% lead, with 2515 versus 1351. Find prime numbers shows a 66.1% lead, with 248 versus 84. Data encryption shows a 21.1% lead, with 23881 versus 18838. Extended instructions show a 7.2% lead, with 24017 versus 22298. PassMark multithread goes to Intel with 30659 versus 26646, a 13.1% lead.

The overall win count favors Intel at 9 wins versus 6 for AMD, but the average benchmark score favors AMD at 39603 versus 36699. The AMD part also holds a higher percentile rank at 87 versus 85.

The Verdict

The data describes two processors with different optimization targets. The AMD Ryzen 7 PRO 8840HS delivers higher average benchmark scores and sits higher in the overall CPU percentile ranking. It leads in multi-core Cinebench R15 and R23, integer math, data compression, and random string sorting. Those results point toward workloads that rely on integer arithmetic, compression, and classic multi-threaded rendering tasks.

The Intel Arc G3 EXTREME wins more individual tests, especially in floating-point math, physics, prime number finding, encryption, and single-thread performance. Its PassMark single-thread score of 4293 is notably higher than the AMD score of 3692, and its Cinebench R23 single-core score of 1862 confirms a single-thread advantage. The 66.1% lead in prime number finding and the 46.3% lead in physics indicate strong execution on specialized workloads.

For users prioritizing multi-threaded integer workloads and overall average performance, the AMD Ryzen 7 PRO 8840HS is the stronger choice based on the recorded data. For users prioritizing floating-point math, encryption, physics simulation, or single-thread responsiveness, the Intel Arc G3 EXTREME shows clear advantages. The Intel part also offers higher memory bandwidth at 136.5 GB/s versus 89.6 GB/s, which may factor into memory-sensitive tasks. The AMD part offers ECC memory support, which the Intel part lacks.

The final selection depends on workload type. The AMD processor wins the aggregate score comparison, while the Intel processor wins the majority of individual tests. The database shows 6 wins for AMD and 9 wins for Intel, but the AMD wins include the more widely used Cinebench multi-core benchmarks. The Intel wins are more numerous but concentrated in specific PassMark subtests. Both processors are active mobile parts with locked multipliers, so the decision rests on which benchmark family matters more.
