CPU Comparison

The AMD Ryzen Threadripper 2920X and the Intel Atom x7433RE represent two extreme poles of the processor market, and the benchmark data reflects a complete mismatch in几乎所有 metrics. The Threadripper 2920X, a 12-core, 24-thread desktop powerhouse from the 2000 series, utterly dominates the Atom x7433RE in every single head-to-head test conducted. The Atom, a 4-core, 4-thread mobile part based on the Gracemont architecture, is not competitive in raw compute, yet it holds its own in the broader database ranking due to its specialized strengths. This analysis breaks down the data to show where each processor wins, which one is the right choice for which task, and the architectural reasons behind the massive performance gap.

Where Each One Wins

The data is unambiguous: the AMD Ryzen Threadripper 2920X wins in every category of raw processing power. The head-to-head benchmark table shows a clean sweep, with the Threadripper taking all five tests and the Atom taking zero. The Threadripper’s wins are not marginal; they are overwhelming. For instance, in Cinebench R23 multi-core, the Threadripper scores 21,380 points against the Atom’s 3,535, a delta of 504.8%. This pattern repeats across all Cinebench versions and single-core tests, indicating a fundamental advantage in both parallel and single-threaded workloads.

The Intel Atom x7433RE, conversely, does not win any of the shared head-to-head benchmarks. However, its inclusion in the database with a percentile rank of 61, the same as the Threadripper, suggests its strengths lie elsewhere. The Atom’s benchmark suite includes PassMark tests for data compression, encryption, and extended instructions, which are not present for the Threadripper. In these specialized workloads, the Atom shows capability, with a PassMark data compression score of 43,671 and a data encryption score of 3,029. These scores indicate that while it cannot match the Threadripper’s brute force, it is a competent processor for specific, low-power tasks where its 9W TDP is a critical advantage.

The use-case split is therefore clear: the Threadripper is designed for compute-intensive desktop work, while the Atom is tailored for low-power, embedded or mobile applications that prioritize efficiency over peak performance. The Threadripper wins on every measurable benchmark, but the Atom wins on power efficiency and integration, featuring an integrated UHD Graphics 32EU, a feature entirely absent from the Threadripper.

The Verdict

For users who need maximum processing power, the AMD Ryzen Threadripper 2920X is the definitive choice. The data shows it is, on average, 505% faster than the Atom in multi-core Cinebench tests, and its 12 cores and 24 threads provide a level of parallel performance that the Atom cannot approach. Its average benchmark score of 5,730 places it in the 61st percentile of all CPUs, and it trades blows with rivals like the AMD EPYC 7351 (0.4% delta) and the Intel Xeon W-2175 (-0.7% delta), indicating it holds its own among server-class parts.

The Intel Atom x7433RE is the correct pick for a completely different set of requirements. With a TDP of just 9W compared to the Threadripper’s 180W, it is designed for scenarios where power consumption is the primary constraint. Its 4 cores and 4 threads are sufficient for light, efficiency-focused tasks, and its integrated graphics eliminate the need for a separate GPU. The Atom’s average benchmark score of 5,601 is remarkably close to the Threadripper’s, but this is misleading; the Atom’s score is buoyed by its PassMark tests, which are not directly comparable to the Threadripper’s Cinebench results. In direct competition, the Atom loses every time.

In short, the Threadripper 2920X is for the user who demands performance above all else, while the Atom x7433RE is for the user who demands efficiency and integration above all else. There is no middle ground in the data.

Head-to-Head Benchmarks

The most striking result in the entire dataset is the Cinebench R15 multi-core test. The Threadripper scores 2,154 points, while the Atom scores just 356, yielding a delta of 505.1%. This test is a strong indicator of multi-threaded rendering performance, and the Threadripper’s 12-core, 24-thread configuration crushes the Atom’s 4-core, 4-thread design.

The gap persists in Cinebench R20, where the Threadripper’s multi-core score of 8,979 dwarfs the Atom’s 1,484, again a 505.1% difference. The single-core results are similarly lopsided: the Threadripper scores 1,267 in R20 single-core versus the Atom’s 209, a 506.2% delta. This shows that even in workloads that rely on a single thread, the Threadripper’s higher boost clock of 4.30 GHz and more advanced Zen+ architecture provide a decisive advantage over the Atom’s 3.40 GHz boost.

The latest Cinebench R23 results continue the trend. In multi-core, the Threadripper scores 21,380 against the Atom’s 3,535, a 504.8% delta. In single-core, the Threadripper scores 3,018 against the Atom’s 499, also a 504.8% delta. These consistent deltas across all benchmark versions suggest a fixed architectural performance ratio rather than a workload-specific anomaly. The Threadripper’s higher memory bandwidth of 93.9 GB/s (quad-channel DDR4) versus the Atom’s 38.4 GB/s (single-channel) likely contributes to these sustained margins, especially in memory-sensitive workloads.

The biggest win for the Threadripper is in Cinebench R20 single-core, where the 506.2% delta is the highest recorded in the head-to-head table. This result underscores that the Threadripper’s advantage is not merely about core count; its individual cores are vastly more capable than the Atom’s Gracemont cores.

Architecture Differences

The architectural divide between the two processors is stark and explains the performance gulf. The AMD Ryzen Threadripper 2920X is built on the Zen+ architecture, codenamed Colfax, using a 12 nm process at GlobalFoundries. It features a dual-die design with a die size of 2x 213 mm² and contains 9,600 million transistors. Its cache hierarchy includes 96 KB of L1 per core, 512 KB of L2 per core, and a substantial 32 MB of L3 cache. It supports DDR4 memory via a quad-channel bus, delivering 93.9 GB/s of bandwidth. The processor also offers 60 PCIe Gen 3 lanes and an unlocked multiplier, making it a flexible desktop part. Its release date is October 2, 2018, with a launch MSRP of $649.

In contrast, the Intel Atom x7433RE is based on the Amston Lake architecture, using the Gracemont core design, and is manufactured on a 10 nm process at Intel. It is a single-chip design with a shared 2 MB L2 cache and a 6 MB shared L3 cache. It supports both DDR4 and DDR5 memory, but only via a single-channel bus, yielding a much lower 38.4 GB/s bandwidth. The Atom features 9 PCIe Gen 3 lanes and an integrated UHD Graphics 32EU, making it a system-on-chip solution. Its TDP is a mere 9W, and it has a locked multiplier, reflecting its mobile and embedded market segment. It was released on April 7, 2024, with a launch MSRP of $63.

The foundry and process node differences are notable: GlobalFoundries’ 12 nm for AMD versus Intel’s 10 nm for the Atom. The Threadripper’s two-die design with a massive L3 cache is geared toward high-throughput desktop computing, while the Atom’s single-die, low-power design with integrated graphics is optimized for efficiency. The memory support further diverges, with the Threadripper’s quad-channel DDR4 versus the Atom’s single-channel DDR4/DDR5. These architectural choices dictate that the Threadripper is a performance-first processor, while the Atom is an efficiency-first processor, with no overlap in their intended use cases.
