AMD Ryzen 9 9900X vs Intel Core 5 320 Comparison

Head-to-Head Benchmarks

The recorded head-to-head data shows a decisive sweep: the AMD Ryzen 9 9900X wins all 15 benchmark comparisons, with the Intel Core 5 320 taking zero wins. The margins are substantial across every workload category, but the size of the gap varies widely depending on whether the test is single-threaded or multi-threaded.

The largest difference appears in PassMark integer math, where the Ryzen 9 9900X scores 181,056 against the Core 5 320's 32,323, a delta of 460.1%. Cinebench R23 multi-core shows a similar story: 32,172 versus 6,197, a 419.2% advantage. These are not marginal leads; they indicate fundamentally different performance tiers.

Multi-threaded workloads generally show the biggest gaps. PassMark data compression gives the AMD part a 359.5% lead (683,579 vs 148,779), while extended instructions show 316.6% (55,243 vs 13,262). Random string sorting follows at 299.2% (72,013 vs 18,038), and find prime numbers trails at 296.4% (436 vs 110). The Cinebench R15 multi-core test shows a 375.1% delta (5,008 vs 1,054), and data encryption lands at 204.3% (33,421 vs 10,984).

Single-thread and lightly-threaded tests still favor the Ryzen 9 9900X, but by far smaller margins. PassMark single-thread shows 4,672 versus 4,045, a 15.5% lead. Cinebench R23 single-core gives 2,253 versus 1,926, a 17% advantage. The R15 single-core test shows 353 versus 276, which is 27.9%. These narrower gaps suggest the Intel part has competitive per-core capability, but it cannot overcome the core-count deficit in parallel workloads.

Intermediate tests fall in between. PassMark multithread shows a 253.7% lead (54,643 vs 15,450), floating point math gives 182.9% (120,083 vs 42,440), and physics lands at 176.9% (3,381 vs 1,221). The pattern is consistent: the more threads that can be utilized, the larger the AMD advantage becomes.

Architecture Differences

The two processors sit in different market segments with different design priorities. The AMD Ryzen 9 9900X is a desktop part built on the Zen 5 architecture, codenamed Granite Ridge, from the 9000 series. It uses a 4 nm process from TSMC with 16,630 million transistors across a dual-die design totaling 2x 70.6 mm². The Intel Core 5 320 is a mobile processor with the Wildcat Lake codename, built on Intel's 3 nm process, and the database records no transistor count or die size for it.

Core and thread counts differ sharply. The Ryzen 9 9900X provides 12 cores and 24 threads with simultaneous multithreading. The Core 5 320 provides 6 cores and 6 threads, with no multithreading capability recorded. Cache organization also diverges: the AMD part has 80 KB of L1 per core, 1 MB of L2 per core, and 64 MB of L3 cache. The Intel part has 192 KB of L1 total, 2.5 MB of L2, and 6 MB of shared L3.

Memory architecture adds another layer of separation. The Ryzen 9 9900X supports DDR5 over a dual-channel bus with 89.6 GB/s of bandwidth and ECC memory support. The Core 5 320 supports DDR5 and LPDDR5X over a single-channel bus with 59.7 GB/s of bandwidth and no ECC support. PCIe connectivity also differs: the AMD processor offers Gen 5 with 24 CPU lanes, while the Intel processor offers Gen 4 with 6 CPU lanes.

Integrated graphics are present on both, but they are different implementations. The Ryzen 9 9900X uses Radeon Graphics, while the Core 5 320 uses Intel Xe3 Graphics with 2 Xe cores. The AMD part has an unlocked multiplier and a listed part number of 100-000000662; the Intel part is locked and carries the part number SAE3H.

The Verdict

The data points to a straightforward conclusion for most workloads. The AMD Ryzen 9 9900X outscores the Intel Core 5 320 in every recorded benchmark, with the largest gaps appearing in multi-threaded tasks. The 12-core, 24-thread configuration with a 120-watt TDP and dual-channel memory provides a level of parallel performance that the 6-core, 6-thread, 15-watt mobile part cannot approach. The average benchmark score of 57,498 versus 18,023, combined with a 92nd percentile versus a 72nd percentile ranking among all CPUs, confirms the AMD part occupies a higher performance tier.

The Intel Core 5 320 still holds relevance in its segment. Its single-thread scores are within 15.5% to 27.9% of the Ryzen 9 9900X despite having a base clock of 1.50 GHz versus 4.40 GHz. The 3 nm process and 15-watt TDP indicate a design focused on power efficiency for mobile use. The integrated Intel Xe3 Graphics with 2 Xe cores and support for LPDDR5X memory point to a platform designed for compact, battery-conscious systems rather than maximum throughput.

For a desktop user selecting between these two, the benchmark results clearly favor the Ryzen 9 9900X. For a mobile system designer, the Core 5 320's specifications align with a different set of constraints. The choice depends entirely on whether the workload demands multi-threaded throughput or low-power mobility.

Where Each One Wins

The AMD Ryzen 9 9900X wins in every benchmark category recorded in the head-to-head data. Its strengths are most pronounced in integer math, where it leads by 460.1%, and in Cinebench R23 multi-core, where it leads by 419.2%. Data compression (359.5%), extended instructions (316.6%), and random string sorting (299.2%) all show massive advantages. These are workloads that scale with core count, thread count, and memory bandwidth, all of which favor the AMD part.

Single-threaded and lightly-threaded tests are the only areas where the Intel Core 5 320 approaches competitiveness. PassMark single-thread shows a 15.5% gap, Cinebench R23 single-core shows a 17% gap, and Cinebench R15 single-core shows a 27.9% gap. These are the Intel part's best relative results, though they still result in an AMD win. The Core 5 320 also holds advantages in power-related specifications: a 15-watt TDP versus 120 watts, a 3 nm process versus 4 nm, and support for LPDDR5X memory. The mobile segment designation and BGA 1516 socket indicate the Intel part is designed for laptops where power draw and physical footprint matter more than raw compute. In such a context, the single-thread performance is respectable, but the recorded data does not show any benchmark where the Core 5 320 takes the lead.
