AMD Ryzen 5 8600G vs Intel Arc G3 EXTREME Comparison

Head-to-Head Benchmarks

The benchmark comparison between the AMD Ryzen 5 8600G and the Intel Arc G3 EXTREME reveals a split personality. Intel wins 13 of the 17 recorded head-to-head tests, but the AMD chip claims the most dramatic victories in the latest Cinebench iterations. The single largest margin belongs to AMD in Cinebench R23 single-core, where the Ryzen 5 8600G scores 3035 against Intel’s 1862, a 63% advantage. That gap is enormous and suggests a fundamental difference in how each processor handles lightly threaded workloads.

Cinebench R23 multi-core also favors AMD, with the Ryzen 5 8600G posting 21503 versus 14655 for the Arc G3 EXTREME, a 46.7% lead. These two results are striking because they contradict the pattern seen in earlier Cinebench releases. In Cinebench R15 multi-core, Intel edges ahead by a slim 2192 to 2167, a 1.1% margin. In Cinebench R20 multi-core, Intel wins decisively with 10945 against 9031, a 17.5% advantage. The R20 single-core test also goes to Intel, 1545 to 1274, another 17.5% gap. The reversal between R20 and R23 is notable: the data shows Intel dominating the older R20 workload while AMD dominates the newer R23 workload, which may indicate different optimization paths or thermal behavior under sustained load.

Outside Cinebench, Intel’s wins are consistent but vary in magnitude. PassMark floating point math shows Intel at 86929 versus 47919 for AMD, a 44.9% lead. PassMark physics delivers a 2515 to 1450 win for Intel, a 42.3% margin. Prime number finding goes to Intel by 248 to 96, a 61.3% gap, which is the second-largest delta in the entire comparison. Data encryption favors Intel at 23881 versus 17181, a 28.1% margin. Multi-thread performance in PassMark gives Intel 30659 against 25294, a 17.5% lead, matching the Cinebench R20 margin.

AMD’s remaining wins beyond Cinebench R23 are narrower. PassMark integer math goes to AMD by 77042 to 71164, an 8.3% margin. The single-thread PassMark test goes to Intel, however, with 4293 versus 3878, a 9.7% gap. Data compression, extended instructions, and random string sorting all favor Intel by single-digit margins: 4.5%, 5.9%, and 6.1% respectively. The aggregate picture shows Intel ahead in raw throughput across most measured categories, but AMD’s commanding lead in the most recent Cinebench versions raises questions about workload recency and scaling behavior.

Architecture Differences

The two processors come from opposite design philosophies. The AMD Ryzen 5 8600G uses the Zen 4 architecture on a 4 nm TSMC process, codenamed Phoenix. It has 6 cores and 12 threads, with a base clock of 4.30 GHz and a boost clock of 5.00 GHz. The Intel Arc G3 EXTREME uses the Panther Lake codename, built on a 3 nm Intel process, with 14 cores and 14 threads. Its base clock is 1.90 GHz and boost reaches 4.70 GHz. The core count difference is substantial, but Intel’s thread count equals its core count, meaning no simultaneous multithreading, while AMD doubles its threads through SMT.

Cache organization differs notably. AMD allocates 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. Intel provides 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. Intel’s larger per-core L1 and L2 caches may explain its strength in certain integer and floating point operations, while AMD’s smaller cache per core is paired with higher clock speeds.

The memory subsystem also diverges. AMD supports DDR5 with dual-channel access and 83.2 GB/s of bandwidth. Intel supports LPDDR5X, also dual-channel, but delivers 136.5 GB/s. That 53.3 GB/s difference in theoretical bandwidth likely contributes to Intel’s wins in memory-sensitive workloads like data compression and encryption. The process node difference, 4 nm for AMD versus 3 nm for Intel, gives Intel a density advantage, though the transistor count and die size for Intel are not recorded in the database.

PCIe connectivity shows a sharp contrast. AMD offers Gen 4 with 20 lanes, while Intel offers Gen 5 with only 4 lanes. This makes AMD more suitable for expandability with multiple devices, while Intel’s lane count is minimal, fitting its mobile market segment. Intel’s socket is BGA 2540, which is soldered, while AMD uses Socket AM5, which supports socketed installation. The integrated graphics also differ: AMD uses the Radeon 760M, while Intel uses the Arc B390. Intel’s TDP is 25 watts versus AMD’s 65 watts, a 40-watt gap that explains why Intel can sustain high throughput in some tests despite lower clock speeds.
