AMD Ryzen 7 5700X3D vs Intel Core 3 305 Comparison

Head-to-Head Benchmarks

The benchmark data presents a decisive overall victory for the AMD Ryzen 7 5700X3D, which wins 15 of the 17 recorded head-to-head comparisons. The Intel Core 3 305 manages only 2 wins, both in single-threaded PassMark tests. The scale of the AMD advantage is consistent across most workloads, with the Ryzen chip frequently doubling or more than doubling the Intel part's output.

In multi-core rendering, the AMD Ryzen 7 5700X3D dominates. The Cinebench R23 multicore score stands at 22366 against 13123 for the Intel Core 3 305, a 70.4% advantage. The pattern repeats across the Cinebench suite: R15 multicore shows 2254 versus 1322 (70.5% delta), and R20 multicore shows 9393 versus 5511 (70.4% delta). These results confirm that the Ryzen chip's additional cores and threads translate directly into rendering throughput.

Single-core Cinebench results also favor AMD, though the margin is narrower in absolute terms. The Ryzen 7 5700X3D scores 3157 in Cinebench R23 single-core, compared to 1852 for the Core 3 305, a 70.5% difference. Similar gaps appear in R15 single-core (318 versus 186, 71% delta) and R20 single-core (1325 versus 777, 70.5% delta). This is notable because the Intel part has a higher boost clock of 4.30 GHz versus 4.10 GHz, yet the AMD architecture still extracts more single-thread performance in these tests.

The PassMark suite reveals where the AMD chip's strengths are most pronounced. Integer math shows the largest margin: 81257 for AMD against 32295 for Intel, a 151.6% advantage. Data compression follows with 307237 versus 146857 (109.2% delta). Physics tests show 2686 versus 1233 (117.8% delta), and prime number finding shows 224 versus 115 (94.8% delta). These are workloads that scale with core count, cache size, and memory bandwidth, all areas where the Ryzen 7 5700X3D holds structural advantages.

Floating-point math is the closest multi-threaded contest. The AMD part scores 46492 versus 42284 for Intel, a modest 10% lead. Extended instructions show a 56.6% delta (21202 versus 13543), while random string sorting shows 78.7% (31492 versus 17623). Data encryption, multithread, and data compression all cluster around the 70.5% to 109.2% range, reinforcing the consistent multi-threaded superiority of the AMD processor.

The Intel Core 3 305's only wins come in the PassMark single-thread and singlethread tests, where it scores 3977 against 2970 for AMD, a 25.3% advantage. This is a significant single-thread win, suggesting that for lightly threaded workloads that rely on raw clock speed and modern core design, the Intel part holds an edge. However, this advantage does not carry into the Cinebench single-core tests, where AMD wins by roughly 70%, indicating that the PassMark single-thread test exercises different aspects of the core pipeline.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 7 5700X3D is a desktop part built on the Zen 3 architecture with the Vermeer codename, manufactured by TSMC on a 7 nm process. It uses 8,850 million transistors on a 74 mm² die. The Intel Core 3 305 is a mobile processor with the Wildcat Lake codename, built on Intel's 3 nm process, with transistor count and die size not recorded in the database.

Core and thread counts diverge sharply. The AMD chip provides 8 cores and 16 threads, while the Intel chip provides 6 cores and 6 threads. The Intel part has no hyper-threading, which explains much of the multi-threaded performance gap. The Ryzen chip's base clock is 3.00 GHz with a 4.10 GHz boost, while the Intel part runs at 1.50 GHz base and 4.30 GHz boost. The lower Intel base clock is typical for a mobile-oriented design focused on power efficiency.

Cache architecture differs substantially. The AMD Ryzen 7 5700X3D features 64 KB of L1 cache per core, 512 KB of L2 per core, and 96 MB of shared L3 cache. The Intel Core 3 305 has 192 KB of L1 total, 2.5 MB of L2, and 6 MB of shared L3 cache. The AMD chip's 96 MB L3 cache is 16 times larger than the Intel part's 6 MB, a critical factor for workloads that benefit from large on-die data residency.

Memory support reveals different target segments. The AMD processor uses DDR4 with dual-channel memory and a recorded bandwidth of 51.2 GB/s, plus ECC support. The Intel part supports DDR5 and LPDDR5X but only through a single-channel memory bus, with 59.7 GB/s bandwidth and no ECC. Despite the faster memory standard, the single-channel configuration limits the Intel part's effective memory throughput in multi-threaded scenarios.

PCIe connectivity also differs. The AMD chip provides Gen 4 with 20 lanes from the CPU, while the Intel chip provides Gen 4 with only 6 lanes. Integrated graphics are absent on the AMD part, while the Intel Core 3 305 includes Intel Xe3 Graphics with 1 Xe core, making it a viable option for systems without a discrete GPU.

The AMD processor uses the AMD Socket AM4, a long-lived desktop platform, while the Intel chip uses Intel BGA 1516, a soldered mobile socket. The AMD part has a 105 W TDP, while the Intel part is rated at 15 W, reflecting the mobile design intent of the Core 3 and the desktop performance focus of the Ryzen 7. Production status for both is listed as Active.

Where Each One Wins

The AMD Ryzen 7 5700X3D is the clear choice for multi-threaded and cache-sensitive workloads. The data shows wins across all Cinebench multi-core tests, with deltas around 70.4% to 70.5%. The PassMark multithread test shows a 70.5% advantage, and data compression shows a 109.2% lead. The 96 MB L3 cache and 16 threads give it a decisive edge in rendering, video encoding, data compression, encryption, and physics simulations. The 151.6% lead in integer math and 117.8% lead in physics specifically point to compute-heavy tasks that scale with core count and cache depth.

The Intel Core 3 305 wins only in PassMark's single-thread and singlethread tests, with a 25.3% margin. This indicates that for purely serial workloads where a single core is the bottleneck, the Intel part's higher 4.30 GHz boost clock and newer 3 nm process deliver better raw throughput. The PassMark single-thread test appears to reward clock speed and per-core efficiency more than the Cinebench single-core tests, where AMD still leads by 70.5%. The Intel part also includes integrated graphics, making it suitable for compact or low-power systems where a discrete GPU is not present, though no graphics benchmarks are recorded in the database.

The floating-point math test is the closest multi-threaded result, with AMD ahead by just 10%. This suggests that for pure floating-point throughput, the architectural differences between Zen 3 and the Wildcat Lake core narrow considerably, even with the AMD part's core and cache advantages. However, this is an outlier; in every other multi-threaded test, the AMD lead exceeds 56%.

For mobile or power-constrained environments, the Intel Core 3 305's 15 W TDP and BGA socket position it differently, but the benchmark data does not include power efficiency metrics. The AMD part's 105 W TDP and desktop socket target a different usage model entirely.
