AMD Ryzen 3 7330U vs AMD Ryzen Threadripper 1900X Comparison

The Verdict

The AMD Ryzen Threadripper 1900X and AMD Ryzen 3 7330U occupy entirely different corners of the processor market, and the benchmark data reflects that split clearly. The Threadripper 1900X wins the head-to-head comparison with 2 wins out of 3 tests, dominating in multi-core workloads. Its Cinebench R23 multi-core score of 14286 is 129.3% higher than the 7330U's 6230, and its Geekbench multi-core score of 6588 beats the 7330U's 4131 by 59.5%. For users running heavily threaded desktop workloads, the Threadripper 1900X is the clear choice based on the recorded data.

The Ryzen 3 7330U takes the single-core crown, scoring 1514 in Geekbench single-core versus 1205 for the Threadripper, a 20.4% advantage. This makes the 7330U the better option for tasks that rely on single-thread responsiveness, especially given its mobile design. The data shows both processors sit at the 57th percentile among all CPUs, meaning they are statistically peers in overall standing despite their architectural differences.

The verdict is straightforward: the Threadripper 1900X is for desktop users who need raw multi-threaded compute, while the Ryzen 3 7330U is for laptop buyers who want modern single-core performance and efficiency. Neither is a universal winner, and the choice depends entirely on the workload and platform.

Architecture Differences

The two processors come from different eras and design philosophies. The Threadripper 1900X is based on the original Zen architecture, codenamed Zen, and belongs to the "Ryzen Threadripper (Zen (Whitehaven))" generation from the 1000 series. It uses a 14 nm process node fabricated by GlobalFoundries. The 7330U uses the Zen 3 architecture, codenamed Barcelo-R, from the "Ryzen 3 (Zen 3 (Cezanne))" generation in the 7000 series, built on a 7 nm process by TSMC. This generational gap explains much of the performance-per-clock difference between them.

The Threadripper packs 8 cores and 16 threads, double the 7330U's 4 cores and 8 threads. Its L1 cache is 96 KB per core while the 7330U has 64 KB per core, and both share 512 KB L2 per core. The L3 cache tells a different story: the Threadripper has 32 MB of L3, while the 7330U has 8 MB of shared L3. The Threadripper also uses a dual-die design with a die size of 2x 213 mm² and 9,600 million transistors, whereas the 7330U is a monolithic 180 mm² die with 10,700 million transistors. The newer 7 nm process allows the mobile chip to pack more transistors into a smaller area.

The Threadripper is a desktop part with a TDP of 180 W, while the 7330U is a mobile part with a TDP of 15 W. This 12x difference in power envelope is fundamental to their designs. The Threadripper uses the AMD Socket SP3r2, while the 7330U uses the AMD Socket FP6. The Threadripper has an unlocked multiplier, making it overclockable, while the 7330U does not. The 7330U includes integrated Radeon Graphics (Vega 4), while the Threadripper has no integrated graphics at all.

Head-to-Head Benchmarks

The multi-core tests heavily favor the Threadripper 1900X. In Cinebench R23 multi-core, the Threadripper scores 14286 against the 7330U's 6230, a massive 129.3% lead. This is the largest delta in the head-to-head data and reflects the Threadripper's 8-core, 16-thread configuration against the 7330U's 4-core, 8-thread setup. The 7330U's higher boost clock of 4.30 GHz cannot compensate for the Threadripper's core advantage in this all-core workload.

Geekbench multi-core shows a similar pattern, with the Threadripper scoring 6588 versus 4131 for the 7330U, a 59.5% difference. The smaller margin here compared to Cinebench suggests the Geekbench workload is less sensitive to raw core count and more reliant on memory bandwidth and cache behavior, areas where the Threadripper's quad-channel DDR4 memory bus with 85.3 GB/s bandwidth provides an edge over the 7330U's dual-channel 51.2 GB/s.

The single-core test flips the result. In Geekbench single-core, the 7330U scores 1514, beating the Threadripper's 1205 by 20.4%. This is a significant margin and highlights the architectural leap from Zen to Zen 3. The 7330U's 4.30 GHz boost clock, combined with the newer 7 nm process and improved IPC, delivers a clear single-thread victory. The Threadripper's 4.00 GHz boost clock and older Zen architecture cannot keep pace in this test.

Looking at additional recorded benchmarks not in the head-to-head set, the Threadripper shows strong Cinebench scores across versions: 1440 in Cinebench R15 multi-core, 203 in single-core, 6000 in Cinebench R20 multi-core, and 846 in single-core. The 7330U only has Cinebench R23 multi-core recorded at 6230. The Threadripper's average benchmark score across all tests is 4073, while the 7330U's is 3958, placing them nearly level in aggregate performance.

Specification Differences

The two processors differ in nearly every specification category. The Threadripper 1900X has 8 cores and 16 threads, while the 7330U has 4 cores and 8 threads. Base clocks are 3.80 GHz for the Threadripper versus 2.30 GHz for the 7330U, but boost clocks reverse the order: 4.00 GHz for the Threadripper versus 4.30 GHz for the 7330U. TDP is the most dramatic difference: 180 W for the desktop part versus 15 W for the mobile part.

Memory support is DDR4 for both, but the memory bus differs: the Threadripper uses quad-channel while the 7330U uses dual-channel. Memory bandwidth is 85.3 GB/s for the Threadripper versus 51.2 GB/s for the 7330U. ECC memory support also differs: the Threadripper does not support ECC, while the 7330U does. PCIe lanes are another major gap: the Threadripper provides Gen 3 with 60 lanes (CPU only), while the 7330U provides Gen 3 with 16 lanes (CPU only).

Process and packaging differences are substantial. The Threadripper is built on 14 nm at GlobalFoundries with a die size of 2x 213 mm² and 9,600 million transistors. The 7330U is built on 7 nm at TSMC with a die size of 180 mm² and 10,700 million transistors. Cache configurations differ as well: the Threadripper has 96 KB L1 per core and 32 MB L3, while the 7330U has 64 KB L1 per core and 8 MB shared L3. Both have 512 KB L2 per core.

The integrated graphics situation is one-sided: the 7330U includes Radeon Graphics (Vega 4), while the Threadripper has no integrated graphics. The 7330U is a mobile part, while the Threadripper is a desktop part. The Threadripper has an unlocked multiplier, the 7330U does not. Release dates are far apart: the Threadripper launched on 2017-08-30 with a launch MSRP of $549, while the 7330U launched on 2023-01-03. Part numbers are YD190XA8AEWOFYD190XA8U8SAE for the Threadripper and 100-000000944 for the 7330U.
