AMD Ryzen 9 9950X3D vs Intel Core 5 320 Comparison

AMD Ryzen 9 9950X3D vs Intel Core 5 320

The database records a complete sweep in head-to-head testing, with the AMD Ryzen 9 9950X3D winning all 15 benchmark comparisons against the Intel Core 5 320. The average benchmark score for the AMD part is 75,779, placing it in the 95th percentile of all CPUs tracked. The Intel Core 5 320 averages 18,023, which puts it in the 72nd percentile. This is not a close contest by any metric; the performance gap is substantial across every workload category recorded.

Head-to-Head Benchmarks

The largest single margin appears in PassMark integer math, where the AMD Ryzen 9 9950X3D scores 243,209 against the Intel Core 5 320's 32,323. The delta here is 652.4% in favor of AMD. Cinebench R23 multi-core shows a similar scale of difference: 42,018 versus 6,197, a delta of 578%. These two results illustrate the fundamental throughput advantage the AMD processor holds when all cores are engaged.

In Cinebench R15 multi-core, the AMD part scores 6,536 while the Intel part scores 1,054, a delta of 520.1%. PassMark data compression follows at 908,421 versus 148,779, a delta of 510.6%. Extended instruction workloads show 73,011 against 13,262, a delta of 450.5%. Prime number finding records 613 versus 110, a delta of 457.3%. Random string sorting shows 95,423 versus 18,038, a delta of 429%.

The gap narrows considerably in single-threaded tests, though AMD still leads decisively. PassMark single-thread scores are 4,737 for AMD and 4,045 for Intel, a delta of 17.1%. Cinebench R23 single-core shows 2,259 versus 1,926, a delta of 17.3%. Cinebench R15 single-core is closer still at 350 versus 276, a delta of 26.8%. These numbers confirm that while the AMD processor wins every test, its advantage in lightly threaded work is far smaller than in heavily parallel workloads.

The remaining benchmarks show deltas between 276.4% and 364.4%. PassMark floating point math records 159,724 versus 42,440, a delta of 276.4%. Data encryption shows 44,536 versus 10,984, a delta of 305.5%. PassMark multi-thread scores 70,255 versus 15,450, a delta of 354.7%. Physics simulation records 5,670 versus 1,221, a delta of 364.4%. The AMD Ryzen 9 9950X3D also has additional benchmark entries in the database, including 3DMark tests and Geekbench scores, which are not part of the direct head-to-head comparisons but contribute to its overall average.

Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen 9 9950X3D uses the Zen 5 architecture on the Granite Ridge codename, built on a 4 nm process at TSMC. It has 16 cores and 32 threads, with a base clock of 4.30 GHz and a boost clock of 5.70 GHz. The Intel Core 5 320 uses the Wildcat Lake codename, built on a 3 nm process at Intel, with 6 cores and 6 threads. Its base clock is 1.50 GHz and its boost clock is 4.60 GHz.

Cache configurations diverge sharply. The AMD processor has 80 KB of L1 per core, 1 MB of L2 per core, and a large 128 MB L3 cache. The Intel processor has 192 KB of L1 total, 2.5 MB of L2, and 6 MB of shared L3. The AMD design clearly prioritizes large pools of fast cache, which aligns with its higher thread count and multi-core focus. The Intel part has a smaller cache footprint, consistent with a lower-power mobile design.

Memory support differs as well. The AMD processor supports DDR5 with a dual-channel memory bus and a recorded bandwidth of 89.6 GB/s. It also supports ECC memory. The Intel processor supports DDR5 and LPDDR5X, but uses a single-channel memory bus with a bandwidth of 59.7 GB/s. ECC memory is not supported on the Intel part. PCIe connectivity also differs: AMD offers Gen 5 with 24 CPU lanes, while Intel offers Gen 4 with 6 CPU lanes.

The TDP figures are not directly comparable given the different market segments. The AMD processor is a desktop part with a 170 W TDP, while the Intel processor is a mobile part with a 15 W TDP. The AMD chip uses an AMD Socket AM5, while the Intel chip uses Intel BGA 1516. The integrated graphics also differ: AMD uses Radeon Graphics, while Intel uses Xe3 Graphics with 2 Xe cores. The AMD processor has an unlocked multiplier, while the Intel processor does not.

The Verdict

The benchmark data shows a clear performance hierarchy. The AMD Ryzen 9 9950X3D wins every recorded comparison against the Intel Core 5 320, often by margins exceeding 400%. The AMD processor is in the 95th percentile of all CPUs, while the Intel processor is in the 72nd percentile. The average benchmark score difference is 57,756 points in favor of AMD.

The Intel Core 5 320 does not win a single head-to-head test. Its closest performance to the AMD part comes in single-threaded workloads, where the delta is around 17%. Even there, the AMD processor holds a comfortable lead. The Intel part is positioned in the mobile segment with a 15 W TDP, while the AMD part is a desktop processor with a 170 W TDP, so the comparison is between a high-end desktop flagship and a low-power mobile chip. The data does not support any scenario where the Intel part outperforms the AMD part in the recorded benchmarks.

Specification Differences

The two processors differ in every major specification category. The AMD Ryzen 9 9950X3D has 16 cores and 32 threads, while the Intel Core 5 320 has 6 cores and 6 threads. Base clocks are 4.30 GHz for AMD and 1.50 GHz for Intel. Boost clocks are 5.70 GHz for AMD and 4.60 GHz for Intel. TDP is 170 W for AMD and 15 W for Intel. The AMD socket is AM5, while the Intel socket is BGA 1516.

Process nodes differ: AMD uses 4 nm at TSMC, while Intel uses 3 nm at its own foundry. Cache sizes are substantially different: AMD has 128 MB of L3, while Intel has 6 MB of shared L3. L1 cache is 80 KB per core for AMD versus 192 KB total for Intel. L2 cache is 1 MB per core for AMD versus 2.5 MB total for Intel. Memory channels are dual for AMD and single for Intel. Memory bandwidth is 89.6 GB/s for AMD and 59.7 GB/s for Intel. ECC support is present on AMD and absent on Intel. PCIe generation is Gen 5 for AMD and Gen 4 for Intel, with 24 lanes versus 6 lanes.

The AMD processor has an unlocked multiplier; the Intel processor does not. The AMD part numbers are 100-000000719, while the Intel part number is SAE3H. The AMD release date is earlier in the database, and the Intel release date is later. The production status for both is listed as active.

Where Each One Wins

The AMD Ryzen 9 9950X3D wins in every category where benchmark data exists. Its largest advantages are in multi-threaded workloads, integer math, data compression, and extended instruction processing. The 652.4% lead in integer math and the 578% lead in Cinebench R23 multi-core point to workloads that scale with core count and large cache. Data compression shows a 510.6% lead, and extended instructions show a 450.5% lead, confirming strength in content creation and scientific computing.

The Intel Core 5 320 does not win any recorded benchmark. Its closest results are in single-threaded tests, where the delta drops to 17.1% in PassMark single-thread and 17.3% in Cinebench R23 single-core. These are still decisive wins for AMD, but they represent the smallest gaps in the dataset. The Intel part also has a much lower TDP at 15 W versus 170 W, so it may fit in systems with stricter power constraints, but the benchmark data does not show any performance advantage to offset that difference.

The database records show the AMD processor in the 95th percentile and the Intel processor in the 72nd percentile. The nearest rivals to the AMD part include the AMD Ryzen 7 PRO 9755 and the Intel Core Ultra 9 285, with deltas of 0.1% and 0.4% respectively. The nearest rivals to the Intel part include the AMD Ryzen 5 1600 and the Intel Core 5 120U, with deltas of 0.2% and 0.7%. These figures place each processor in a different performance tier entirely.
