AMD Ryzen 9 5900XT vs Intel Core 7 350 Comparison

Head-to-Head Benchmarks

The recorded data shows a dominant performance gap between these two processors, with the AMD Ryzen 9 5900XT winning 15 of the 17 benchmark comparisons and the Intel Core 7 350 taking only 2 wins. The largest margin appears in PassMark integer math, where the AMD part scores 177,566 against 33,734, a delta of 426.4%. That result reflects the core-count disparity: 16 physical cores with 32 threads versus 6 cores with 6 threads. The Cinebench R23 multicore test tells a similar story, with the AMD chip posting 37,373 points versus 8,030, a 365.4% advantage.

The AMD processor also leads decisively in data compression and encryption workloads. In PassMark data compression, the Ryzen 9 5900XT scores 597,862 versus 143,123, a 317.7% delta. Data encryption shows 37,814 against 10,933, a 245.9% gap. Random string sorting follows the same pattern: 62,537 versus 17,238, a 262.8% difference. These results indicate that the AMD processor handles memory-intensive and parallel workloads with far greater throughput.

Single-threaded performance is the one area where Intel pulls ahead. In PassMark single-thread, the Core 7 350 scores 4,100 versus 3,474, a 15.3% advantage. This is the only meaningful Intel win, with the second win being the duplicate PassMark single-thread test at the same score. The Cinebench single-core results contradict this pattern, however. In Cinebench R15 single-core, AMD leads 531 to 292, an 81.8% delta. In R20 single-core, AMD leads 2,215 to 758, a 192.2% delta. In R23 single-core, AMD leads 5,276 to 2,046, a 157.9% delta. The discrepancy suggests the PassMark single-thread test rewards different instruction patterns than the Cinebench suite.

The mid-range thread counts also favor AMD strongly. In 3DMark 16-thread tests, the AMD processor scores 10,624; the Intel chip has no recorded 3DMark scores in this database. For the Cinebench R15 multicore test, AMD scores 3,767 versus 1,220, a 208.8% delta. Cinebench R20 multicore shows 15,696 versus 5,373, a 192.1% delta. The AMD processor also leads in PassMark multithread at 43,810 versus 15,170, an 188.8% delta. Even in floating-point math, where Intel architectures historically compete well, AMD leads 99,398 versus 42,809, a 132.2% delta. Prime number finding shows a smaller but still decisive gap: 205 versus 107, a 91.6% delta. Physics simulation scores 1,715 versus 1,173, a 46.2% delta. Extended instructions show 39,141 versus 12,045, a 225% delta.

Architecture Differences

The AMD Ryzen 9 5900XT uses the Zen 3 architecture under the Vermeer codename, fabricated on a 7 nm process at TSMC. It packs 8,300 million transistors across a dual-die layout with each die measuring 74 mm². The Intel Core 7 350 uses the Wildcat Lake codename under the Core 5 generation, fabricated on a 3 nm process at Intel's own foundry. No transistor count or die size is recorded for the Intel part.

The cache structures differ substantially. The AMD processor provides 64 KB of L1 cache per core, 512 KB of L2 per core, and a 64 MB L3 cache. The Intel processor provides 192 KB of L1 per core, 2.5 MB of L2 per core, and a 6 MB shared L3 cache. The AMD L3 cache is more than ten times larger in total, which helps explain its dominance in data-heavy workloads like compression and random string sorting.

Memory support splits along generational lines. The AMD part uses DDR4 with dual-channel memory bus and a recorded bandwidth of 51.2 GB/s. The Intel part uses DDR5 and LPDDR5X with a single-channel memory bus and a recorded bandwidth of 59.7 GB/s. Despite the higher bandwidth figure on the Intel chip, the single-channel configuration and smaller cache limit its effective throughput in parallel tasks.

PCIe connectivity also differs. The AMD Ryzen 9 5900XT provides Gen 4 with 20 CPU lanes. The Intel Core 7 350 provides Gen 4 with only 6 CPU lanes. Integrated graphics are absent on the AMD chip, while the Intel part includes Intel Xe3 Graphics with 2 Xe cores. The AMD processor has an unlocked multiplier, the Intel chip does not.

Specification Differences

The core and thread counts are the most obvious differentiators. The AMD Ryzen 9 5900XT has 16 cores and 32 threads. The Intel Core 7 350 has 6 cores and 6 threads. Base clocks differ significantly: the AMD chip runs at 3.30 GHz, while the Intel chip runs at 1.50 GHz. Boost clocks are identical at 4.80 GHz for both.

The TDP values show a wide gap. The AMD processor is rated at 105 watts, the Intel at 15 watts. This reflects the mobile versus desktop positioning. The AMD part uses AMD Socket AM4, the Intel part uses Intel BGA 1516. The AMD processor is released on 2024-07-30, while the Intel processor carries a release date of 2026-04-15. The launch MSRP for the AMD part is $349. The launch MSRP for the Intel part is $469.

Memory support differs by type and channel configuration. AMD supports DDR4 with dual-channel access and ECC memory. Intel supports DDR5 and LPDDR5X with single-channel access and no ECC. The AMD part has 20 PCIe Gen 4 lanes, the Intel part has 6. The AMD processor has no integrated graphics; the Intel processor includes Intel Xe3 Graphics with 2 Xe cores. The AMD part has a part number of 100-000001581; the Intel part uses SAE3F.

Where Each One Wins

The AMD Ryzen 9 5900XT wins every Cinebench test recorded in the database, including both multicore and single-core variants. The margins range from 81.8% in R15 single-core to 365.4% in R23 multicore. It also wins all PassMark tests except the single-thread test. The largest wins come in integer math, data compression, random string sorting, and data encryption. These results point to workloads that scale with core count, cache size, and memory bandwidth: video rendering, code compilation, database operations, file compression, and scientific computing.

The Intel Core 7 350 wins only the PassMark single-thread test, with a 15.3% advantage over the AMD part. This suggests a narrow edge in applications that are strictly latency-bound and cannot utilize multiple cores. The Intel chip also carries integrated graphics, which the AMD chip lacks, making it suitable for systems that need a display output without a discrete GPU. The 15-watt TDP and mobile socket indicate a design target for battery-powered devices where sustained multicore throughput is secondary to efficiency and compactness.

The AMD processor's 90th percentile ranking among all CPUs, with an average benchmark score of 50,718, places it in the upper tier of the database. Its nearest rivals include the Intel Core i9-14900T with an average score of 51,015 and a delta of -0.6%, and the Intel Core i9-13980HX at 50,398 with a delta of 0.6%. The Intel Core 7 350 sits at the 71st percentile with an average score of 17,779. Its nearest rivals are the Intel Core 5 221TE at 17,860, the AMD EPYC 9374F at 17,693, the AMD Ryzen 5 3600XT at 17,891, and the Intel Core 5 120U at 17,898.

The Verdict

The benchmark data presents a clear split by use case. The AMD Ryzen 9 5900XT is the stronger processor in nearly every measured workload. Its 16-core, 32-thread configuration with 64 MB of L3 cache and dual-channel DDR4 support delivers multicore performance that is between 46.2% and 426.4% ahead of the Intel Core 7 350 across the recorded tests. The average benchmark score of 50,718 versus 17,779 puts the AMD part in a different performance class, confirmed by the 90th versus 71st percentile rankings.

The Intel Core 7 350 wins the PassMark single-thread test by 15.3%, which indicates a genuine advantage in lightly threaded, latency-sensitive tasks. Its 3 nm process, DDR5 memory support, and integrated Intel Xe3 Graphics make it a more modern package for mobile systems. The 15-watt TDP and single-channel memory bus suggest a design focused on battery life and compactness rather than raw throughput.

Buyers who need maximum processing power for rendering, compilation, data processing, or any parallel workload should select the AMD Ryzen 9 5900XT based on the multicore deltas recorded here. Buyers who prioritize single-thread responsiveness, integrated graphics, low power consumption, or a mobile form factor should consider the Intel Core 7 350. The data does not support a conclusion that the Intel chip competes with the AMD part in aggregate performance; the two serve different market segments with different priorities.
