AMD Ryzen 7 PRO 8845HS vs Intel Arc G3 EXTREME Comparison

Head-to-Head Benchmarks

The benchmark record splits almost evenly between these two mobile processors: the AMD Ryzen 7 PRO 8845HS takes 8 wins, while the Intel Arc G3 EXTREME takes 9, but the margin distribution tells a more complex story than the raw win count suggests.

The AMD Ryzen 7 PRO 8845HS posts its largest victory in Cinebench R23 single-core, scoring 3468 against the Intel Arc's 1862, a 86.3% advantage. The same pattern appears in Cinebench R23 multi-core, where AMD scores 24565 versus 14655, a 67.6% lead. These are the two most substantial gaps in the entire comparison, and they establish AMD's dominance in sustained rendering workloads that scale with core count and clock speed.

AMD also wins Cinebench R15 multi-core (2476 vs 2192, +13%) and Cinebench R15 single-core (349 vs 267, +30.7%). In PassMark integer math, AMD scores 97625 versus 71164, a 37.2% edge. Data compression goes AMD's way at 343952 versus 307094 (+12%), as does random string sorting at 41867 versus 37331 (+12.2%). Extended instructions show a narrower AMD advantage at 25434 versus 24017 (+5.9%).

The Intel Arc G3 EXTREME counters with equally decisive wins in several workloads. Its PassMark floating-point math score of 86929 dwarfs AMD's 58965, a 32.2% margin.

Specification Differences

The two processors differ across nearly every specification field. The AMD Ryzen 7 PRO 8845HS uses 8 cores and 16 threads, while the Intel Arc G3 EXTREME has 14 cores and 14 threads. AMD's base clock is 3.80 GHz and boost clock is 5.10 GHz; Intel's base clock is 1.90 GHz and boost clock is 4.70 GHz. Thermal design power differs substantially: AMD is rated at 45W, Intel at 25W.

Memory support diverges: AMD uses DDR5 with dual-channel configuration and 89.6 GB/s bandwidth, while Intel uses LPDDR5X with dual-channel configuration and 136.5 GB/s bandwidth. ECC memory is supported on AMD but not on Intel. PCIe generations differ: AMD provides Gen 4 with 20 lanes (CPU only), Intel provides Gen 5 with 4 lanes (CPU only).

Socket types are incompatible: AMD uses AMD Socket FP7, Intel uses Intel BGA 2540. The integrated graphics differ: AMD includes Radeon 780M, Intel includes Arc B390. Neither processor has an unlocked multiplier. Release dates place AMD at April 2024 and Intel at May 2026. Both are classified as active production mobile processors.

Architecture Differences

The AMD Ryzen 7 PRO 8845HS belongs to the 8000 series and uses Zen 4 architecture on the Hawk Point codename, built on TSMC's 4 nm process. It integrates 25,000 million transistors on a 178 mm² die. Cache layout: 64 KB L1 per core, 1 MB L2 per core, and 16 MB shared L3.

The Intel Arc G3 EXTREME carries no series designation and lists no architecture name, but uses the Panther Lake codename. It is built on Intel's 3 nm process; transistor count and die size are not recorded. Cache layout: 192 KB L1 per core, 2.5 MB L2 per core, and 18 MB shared L3. Intel's larger per-core cache capacities contrast with AMD's smaller per-core caches but larger total core count.

AMD's 16 threads from 8 cores enable simultaneous multithreading, while Intel's 14 threads from 14 cores indicate no multithreading on any core. This structural difference explains why AMD wins threaded rendering tests despite having fewer physical cores, as seen in the 67.6% R23 multi-core margin. Intel's memory bandwidth advantage (136.5 GB/s vs 89.6 GB/s) aligns with its wins in floating-point and encryption tasks.

Where Each One Wins

The AMD Ryzen 7 PRO 8845HS wins in rendering workloads that stress sustained multi-core performance: its Cinebench R23 multi-core score of 24565 versus 14655 demonstrates a 67.6% advantage, and its R23 single-core score leads by 86.3%. For integer-heavy data processing, AMD's 37.2% lead in PassMark integer math (97625 vs 71164) makes it the clear choice. Data compression tasks favor AMD by 12%, and random string sorting by 12.2%. Extended instruction workloads show a smaller 5.9% AMD edge.

The Intel Arc G3 EXTREME takes the scientific and simulation side. Floating-point math at 86929 versus 58965 gives Intel a 32.2% lead, and physics simulation at 2515 versus 1389 represents a 44.8% advantage. Prime-number finding is Intel's strongest domain at 248 versus 87, a 64.9% margin. Data encryption runs 14.2% faster on Intel, and PassMark single-thread performance is 12.4% higher. PassMark multithread also goes Intel's way by 6.8%, and both Cinebench R20 tests (multi and single) favor Intel by roughly 5.7% to 5.8%.

The AMD processor suits users running Cinebench-class rendering, integer math, compression, and general productivity where its higher boost clock (5.10 GHz) and 16 threads matter. The Intel processor suits users focused on floating-point calculations, physics simulation, encryption, and single-thread PassMark workloads, where its higher memory bandwidth (136.5 GB/s) and larger per-core caches appear to provide an advantage.
