AMD Ryzen 7 PRO 5845 vs Intel Arc G3 EXTREME Comparison

Head-to-Head Benchmarks

The recorded data shows a clear split between the Intel Arc G3 EXTREME and the AMD Ryzen 7 PRO 5845, with the Intel part winning 11 of the 17 head-to-head comparisons. However, the magnitude and direction of the wins tell a more nuanced story than the raw win count. The Intel Arc G3 EXTREME dominates in several specialized workloads, while the AMD Ryzen 7 PRO 5845 takes decisive victories in the Cinebench suite and integer-heavy tasks.

The most lopsided result in the entire comparison is PassMark physics, where the Intel Arc G3 EXTREME scores 2515 against the AMD part's 1109, a 126.8% advantage. This is the single largest percentage gap in either direction. Close behind is PassMark find prime numbers, where Intel scores 248 versus AMD's 115, a 115.7% lead. These two results indicate a substantial advantage for the Intel architecture in workloads that stress certain mathematical operations and physics simulation.

Floating point math also favors Intel heavily. The Arc G3 EXTREME records 86929 in PassMark floating point math, while the Ryzen 7 PRO 5845 manages 52105, a 66.8% difference. This is a major margin that suggests the Intel processor is far better suited to scientific and engineering computations that rely on floating-point throughput.

Single-thread performance in PassMark also goes to Intel. The Arc G3 EXTREME scores 4293 in the PassMark single thread test, compared to 3442 for the AMD chip, a 24.7% lead. This is consistent with the Arc G3 EXTREME's higher boost clock of 4.70 GHz versus the Ryzen's 4.60 GHz, though the gap is larger than the clock difference alone would suggest.

The Intel part also leads in data encryption by 20.5% (23881 versus 19815) and in extended instructions by 13.7% (24017 versus 21117). Random string sorting goes to Intel by 10.6% (37331 versus 33754). The PassMark multithread test shows Intel ahead by 17.7% (30659 versus 26054), which is notable given that the AMD part has 16 threads against Intel's 14.

The AMD Ryzen 7 PRO 5845 answers back in the Cinebench suite, where its Zen 3 architecture shows strength. In Cinebench R23 multicore, the AMD chip scores 22145 against Intel's 14655, a 33.8% advantage. The single-core R23 result is even more lopsided: AMD scores 3126 versus Intel's 1862, a 40.4% lead. These are substantial margins that point to a significant architectural difference in how the two processors handle these specific rendering workloads.

Cinebench R15 tells a similar story for AMD. The multicore result favors the Ryzen by a narrow 1.8% (2232 versus 2192), while single-core R15 goes to AMD by 15% (314 versus 267). However, the Cinebench R20 results flip the script. Intel wins R20 multicore by 17.7% (10945 versus 9300) and R20 single-core by 17.8% (1545 versus 1312). This inconsistency between Cinebench versions is striking and suggests that the two processors respond very differently to the workload changes between R20 and R23.

Integer math is another AMD stronghold. The Ryzen 7 PRO 5845 scores 94884 in PassMark integer math against Intel's 71164, a 25% advantage. Data compression also goes to AMD, though narrowly, at 2.3% (314363 versus 307094).

Where Each One Wins

The Intel Arc G3 EXTREME is clearly the choice for workloads that depend on floating-point throughput, cryptography, and specialized instruction sets. Its 66.8% lead in floating point math and 20.5% lead in data encryption make it well suited for scientific computing, financial modeling, and any task that involves heavy mathematical computation. The 115.7% advantage in find prime numbers and 126.8% lead in physics further reinforce this pattern. These are not marginal improvements; they are generational-scale gaps that would meaningfully reduce processing time in these specific tasks.

The Intel part also wins in single-threaded PassMark performance by 24.7%, which suggests that applications that are poorly threaded but sensitive to raw per-core throughput may run faster on the Intel chip, at least according to this benchmark. The multithread PassMark result, which Intel wins by 17.7%, adds another dimension: despite having fewer threads (14 versus 16), the Intel processor manages to outperform in this aggregate measure.

The AMD Ryzen 7 PRO 5845 is the better performer in the Cinebench rendering benchmarks, particularly in R23. The 33.8% multicore and 40.4% single-core leads in R23 are the largest AMD victories in the comparison. For 3D rendering, animation, or any workflow built around Cinema 4D or similar software that uses the Cinebench engine, the data clearly favors AMD.

Integer math is another AMD strength. The 25% lead in PassMark integer math means that database operations, financial calculations, and other integer-heavy tasks are likely to run faster on the Ryzen. The data compression result, while narrow at 2.3%, still goes to AMD, suggesting a slight edge in file archiving and compression workloads.

It is worth remembering the AMD part does not win any of the PassMark tests by a margin larger than 25%, while the Intel part wins several tests by margins above 60%. This means that while AMD has a narrower but consistent advantage in its winning categories, Intel's wins are often more dramatic in magnitude.

The Verdict

The data paints a picture of two processors with fundamentally different strengths. The Intel Arc G3 EXTREME is the pick for users whose workloads center on floating-point math, encryption, physics simulation, and specialized instruction execution. Its wins in PassMark physics (126.8% ahead), find prime numbers (115.7% ahead), and floating point math (66.8% ahead) are far too large to ignore for those application types. Additionally, its 24.7% lead in PassMark single-thread performance suggests that lightly threaded applications may also benefit.

The AMD Ryzen 7 PRO 5845 is the better choice for Cinebench-style rendering workloads, particularly those that use the R23 benchmark engine. The 33.8% multicore and 40.4% single-core leads in R23 are decisive. The 25% advantage in integer math also makes the AMD part attractive for database and integer-heavy enterprise applications.

Both processors sit at the 85th percentile among all CPUs in the database, and their average benchmark scores are close: the Intel part averages 36699, while the AMD part averages 35802. The nearest rivals for each processor also show similar company. The Intel Arc G3 EXTREME sits within 1.1% of the AMD Ryzen AI 7 PRO 450, the AMD Ryzen 5 5500X3D, the AMD Ryzen 5 5600F, and the Intel Core Ultra 5 225. The AMD Ryzen 7 PRO 5845 sits within 0.4% of the Intel Core Ultra 9 185H, the Intel Core 7 250H, and the AMD Ryzen AI 7 PRO 350, and within 0.3% of the AMD Ryzen 7 7700X.

The decision between these two processors should hinge entirely on the specific workload. For rendering and integer-heavy tasks, the AMD Ryzen 7 PRO 5845 is the data-supported choice. For floating-point, encryption, physics, and general PassMark single-thread performance, the Intel Arc G3 EXTREME has the clear edge.
