Where Each One Wins

The AMD Ryzen 7 5800XT is the clear winner for compute-heavy desktop tasks. Its wins span every Cinebench test, covering both single-core and multi-core rendering scenarios. The data shows it is also dominant in integer math, data compression, encryption, random string sorting, and floating point math. For users running software that scales with core count and high memory bandwidth, the AMD processor consistently delivers higher throughput. The 3DMark results for the AMD processor, including 7,683 for 16 threads, 6,141 for 8 threads, and 7,680 for max threads, also point to strong multi-threaded performance, though no shared 3DMark tests exist with the Intel chip.

The Intel Core 3 305 wins only in the PassMark single-thread test, where it scores 3,977 versus 3,535 for the AMD, a 11.1% advantage. This indicates the Intel chip has a slight edge in workloads that are strictly serial and cannot utilize additional cores or threads. However, this single win is isolated, and the Intel processor's overall benchmark profile is substantially lower.

The Intel Core 3 305 uses the Wildcat Lake codename, part of the Core 3 generation. It is built on a 3 nm process from Intel. Its cache includes 192 KB of L1, 2.5 MB of L2, and 6 MB of shared L3 cache. It includes integrated Intel Xe3 Graphics with 1 Xe core. The Intel chip is a mobile processor, while the AMD chip is a desktop processor.

The Verdict

The benchmark data confirms the AMD Ryzen 7 5800XT as the superior performer across the vast majority of tests. Its 81% or greater advantage in every Cinebench test, along with its 190.9% lead in integer math and 139.7% lead in data compression, makes it the clear choice for rendering, content creation, and any multi-threaded workload. The AMD processor also holds a 11.1% advantage in PassMark multithread performance, further solidifying its position for parallel processing.

The Intel Core 3 305 offers a different value profile. Its single-thread win in PassMark, with a score of 3,977, shows it can handle serial tasks competently. Its 15-watt TDP and integrated graphics point toward mobile or low-power applications. The data shows the AMD processor is designed for maximum compute throughput on a desktop platform, while the Intel chip is optimized for efficiency and portability. For users requiring raw processing power, the AMD Ryzen 7 5800XT is the clear winner. For scenarios where power consumption and integrated graphics are priorities, the Intel Core 3 305 has its place, but the recorded benchmarks place it firmly behind the AMD processor in overall capability.
