Architecture Differences

The AMD Ryzen 7 5800XT uses the Zen 3 architecture under the Vermeer codename, built on a 7 nm process at TSMC. It integrates 4,150 million transistors on a 74 mm² die. The Intel Arc G3 EXTREME uses the Panther Lake codename, built on a 3 nm process at Intel, with no transistor or die size data recorded.

Cache layouts differ substantially. The AMD part allocates 64 KB of L1 per core, 512 KB of L2 per core, and 32 MB of shared L3. The Intel part allocates 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The AMD processor therefore has nearly double the L3 capacity, while the Intel processor has larger per-core L1 and L2 allocations.

The AMD Ryzen 7 5800XT supports DDR4 memory over a dual-channel bus with 51.2 GB/s bandwidth and includes ECC memory support. The Intel Arc G3 EXTREME supports LPDDR5X over a dual-channel bus with 136.5 GB/s bandwidth and does not support ECC memory. The Intel part's memory bandwidth is roughly 2.7 times higher in the recorded data.

PCIe connectivity differs: the AMD part provides Gen 4 with 20 CPU lanes, while the Intel part provides Gen 5 with 4 CPU lanes. The Intel processor includes integrated Arc B390 graphics; the AMD processor has no integrated graphics. The AMD part has an unlocked multiplier and uses Socket AM4, while the Intel part is locked, uses BGA 2540, and targets the mobile segment.

Head-to-Head Benchmarks

The AMD Ryzen 7 5800XT dominates Cinebench R23. In multi-core, it scores 23794 versus 14655, a 62.4% lead. In single-core, it scores 3359 versus 1862, an 80.4% lead. These are the two largest deltas in the entire comparison. The AMD part also wins Cinebench R15 multi-core (2398 versus 2192, a 9.4% lead) and R15 single-core (338 versus 267, a 26.6% lead).

The Intel Arc G3 EXTREME reverses the result in Cinebench R20. It wins multi-core with 10945 versus 9993, an 8.7% margin, and single-core with 1545 versus 1410, also an 8.7% margin. This split between R15/R23 favoring AMD and R20 favoring Intel indicates the two processors respond differently to workload scaling across Cinebench versions.

In PassMark tests, the AMD part wins data compression (352002 versus 307094, up 14.6%), extended instructions (24270 versus 24017, up 1.1%), and integer math (93942 versus 71164, up 32%). The Intel part wins data encryption (23881 versus 21461, up 10.1%), find prime numbers (248 versus 119, up 52%), floating-point math (86929 versus 53808, up 38.1%), multithread (30659 versus 28053, up 8.5%), physics (2515 versus 1355, up 46.1%), random string sorting (37331 versus 35911, up 3.8%), and single-thread (4293 versus 3535, up 17.7%).

The Intel part's PassMark single-thread score of 4293 is notable because it wins that test despite having a lower boost clock (4.70 GHz versus 4.80 GHz). The AMD part's integer math win of 32% shows strong ALU throughput, while the Intel part's floating-point win of 38.1% shows stronger FPU throughput. The physics test shows the largest non-Cinebench Intel margin at 46.1%.

Where Each One Wins

The AMD Ryzen 7 5800XT wins in Cinebench R23 by a wide margin, with a 62.4% lead in multi-core and an 80.4% lead in single-core. It also wins Cinebench R15 in both modes. In PassMark, it wins data compression, extended instructions, and integer math. The integer math margin of 32% suggests the Zen 3 cores handle integer-heavy integer workloads with high efficiency. The data compression win of 14.6% reinforces this pattern.

The Intel Arc G3 EXTREME wins Cinebench R20 in both modes, with an 8.7% margin in each. It wins PassMark multithread, single-thread, data encryption, find prime numbers, floating-point math, physics, and random string sorting. The floating-point math win of 38.1% and the physics win of 46.1% indicate strong FPU performance. The find prime numbers score of 248 is more than double the AMD part's 119, a 52% lead that suggests efficient handling of prime-number search algorithms.

The Intel part's multithread win (30659 versus 28053, up 8.5%) is interesting given that it has fewer threads (14 versus 16). The single-thread win (4293 versus 3535, up 17.7%) shows the Panther Lake cores have higher per-thread throughput in PassMark's measurement. The data encryption win of 10.1% points to stronger cryptographic instruction execution.

The Verdict

The recorded data shows two processors with opposing strengths. The AMD Ryzen 7 5800XT is the stronger choice for Cinebench R23 workloads, where it leads by 62.4% in multi-core and 80.4% in single-core. It also leads in integer math, data compression, and extended instructions. The Intel Arc G3 EXTREME is the stronger choice for PassMark single-thread, floating-point math, physics, data encryption, and find prime numbers, plus it wins Cinebench R20 in both modes.

The Intel Arc G3 EXTREME has the higher average benchmark score (36699 versus 29879) and the higher percentile rank (85th versus 81st). It wins 10 of 17 head-to-head tests. The AMD Ryzen 7 5800XT wins 7 tests, but its Cinebench R23 margins are much larger than most of the Intel wins. The Intel part's single-thread score of 4293 versus 3535 is a 17.7% gap, while the AMD part's Cinebench R23 single-core lead is 80.4%.

Users working with Cinebench R23-style rendering workloads should select the AMD Ryzen 7 5800XT based on its decisive margins there. Users prioritizing PassMark physics, floating-point math, or single-thread performance should select the Intel Arc G3 EXTREME. The Intel part also provides integrated Arc B390 graphics and LPDDR5X memory support, while the AMD part provides ECC memory and an unlocked multiplier. The data does not declare a single overall winner; it shows a workload-dependent split.
