AMD Ryzen Threadripper 1920X vs Intel Atom x7433RE Comparison

Head-to-Head Benchmarks

The recorded data shows a complete sweep for the AMD Ryzen Threadripper 1920X across all five shared benchmark tests. The Intel Atom x7433RE does not win a single head-to-head comparison, with the AMD part taking every test by a margin of 82 percent. This uniformity is striking: whether the workload is single-threaded or multi-threaded, the Threadripper 1920X delivers the same relative advantage.

In Cinebench R15 multi-core, the Atom x7433RE scores 356 points against the Threadripper's 1979. That is an 82 percent deficit for the Intel chip. The R20 multi-core test tells the same story: 1484 for the Atom versus 8248 for the Threadripper. The R23 multi-core result is the largest absolute gap in the dataset, with the AMD processor reaching 19640 while the Atom manages only 3535.

Single-thread performance is equally one-sided. In Cinebench R20 single-core, the Atom scores 209, while the Threadripper posts 1164. The R23 single-core test shows 499 for the Atom and 2772 for the AMD chip. The delta percentage is identical in every case: 82 percent in favor of the Ryzen Threadripper 1920X. This consistency suggests the performance difference is structural rather than workload-specific.

The Atom x7433RE does have additional benchmark entries in the database that the Threadripper lacks, including PassMark tests for integer math, floating-point math, data compression, and encryption. These results cannot be compared directly, since the Threadripper has no corresponding scores in those tests. However, the Atom's average benchmark score across all of its recorded tests is 5601, which places it at the 61st percentile of all CPUs. The Threadripper's average benchmark score is 5306, at the 60th percentile. These aggregate figures are close, but they reflect different test sets rather than comparable performance.

Looking at the nearest rivals in the database provides additional context. The Atom x7433RE sits within a tight cluster: the Intel Core i7-12700T averages 5606 (a 0.1 percent difference from the Atom), the AMD Ryzen 7 PRO 3700 averages 5610 (0.2 percent higher), and the Intel Core i9-11900KB averages 5587 (0.3 percent lower). The Atom is essentially at parity with these processors in aggregate benchmark scoring. The Threadripper 1920X, by contrast, is bracketed by the Intel Core i9-9900X at 5301 (0.1 percent higher), the AMD EPYC 7281 at 5315 (0.2 percent higher), and the Intel Core i9-10900KF at 5316 (0.2 percent higher). The Threadripper's aggregate score is also closely matched with its nearest rivals.

These aggregate similarities mask the head-to-head reality. When both CPUs run the same Cinebench tests, the Threadripper 1920X is categorically faster. The Atom's aggregate score benefits from PassMark tests where it records relatively strong numbers, such as 43671 in data compression and 13054 in integer math. But those tests are not available for the Threadripper, so they do not factor into the direct comparison.

The Verdict

The data points to two very different products with little overlap in intended use. The AMD Ryzen Threadripper 1920X wins every shared benchmark by a wide margin, 82 percent across the board. Anyone choosing between these two for compute-heavy tasks, rendering, compilation, or any multi-threaded workload should select the Threadripper without hesitation. Its 12 cores and 24 threads give it a decisive structural advantage over the Atom's 4 cores and 4 threads.

The Intel Atom x7433RE is not competitive in raw performance, but its profile suggests a different role. It draws 9 watts according to the TDP rating, operates from a mobile socket, and includes integrated graphics. The Threadripper, by contrast, is a 180-watt desktop part with no integrated graphics. The Atom's aggregate benchmark percentile is actually one point higher than the Threadripper's, 61 versus 60, but that is a function of the different test suites, not equivalent performance.

For a user who needs single-thread responsiveness, the Threadripper still wins. The R23 single-core score of 2772 versus 499 is an 82 percent margin, the same as the multi-core tests. The Atom does not close the gap in any workload category represented in the shared benchmarks. The verdict is straightforward: the Threadripper 1920X is the choice for performance, the Atom x7433RE is the choice for extremely low power consumption and integrated graphics in a compact mobile package.

Specification Differences

The two processors differ across nearly every specification category. The Intel Atom x7433RE has 4 cores and 4 threads, while the AMD Ryzen Threadripper 1920X offers 12 cores and 24 threads. Base clock speeds are 1.50 GHz for the Atom and 3.50 GHz for the Threadripper, with boost clocks of 3.40 GHz and 4.00 GHz respectively.

The TDP figures represent a major divide: 9 watts for the Atom versus 180 watts for the Threadripper. The sockets are incompatible, with the Atom using Intel BGA 1264 and the Threadripper using AMD Socket SP3r2. The Atom is classified as a mobile part, the Threadripper as a desktop part.

Memory support differs in both type and channel configuration. The Atom supports DDR4 and DDR5 over a single-channel bus with 38.4 GB/s of bandwidth. The Threadripper supports only DDR4 over a quad-channel bus with 85.3 GB/s of bandwidth. Neither CPU supports ECC memory according to the database.

PCIe connectivity is also different. The Atom provides Gen 3 with 9 lanes, while the Threadripper provides Gen 3 with 60 lanes. The Atom includes integrated graphics, the Threadripper does not. The multiplier is locked on the Atom and unlocked on the Threadripper. Release dates are separated by years: the Atom launched in April 2024, the Threadripper in August 2017.

Architecture Differences

The architectural divide is fundamental. The Intel Atom x7433RE is built on the Amston Lake architecture using a 10 nm process at Intel's foundry. Its core generation is listed as Atom (Gracemont). The AMD Ryzen Threadripper 1920X uses the original Zen architecture (codenamed Whitehaven) on a 14 nm process at GlobalFoundries. The Threadripper is part of the 1000 series and belongs to the Ryzen Threadripper generation.

The cache layouts differ substantially. Both CPUs have 96 KB of L1 cache per core. The Atom has 2 MB of shared L2 cache and 6 MB of shared L3 cache. The Threadripper has 512 KB of L2 cache per core and 32 MB of L3 cache. This gives the AMD part a much larger total cache footprint, which aligns with its core count and performance profile.

The Threadripper is a physically large processor, with 9,600 million transistors across two 213 mm² dies. The database does not list transistor count or die size for the Atom. The Threadripper's PCIe lane count of 60 reflects its workstation-oriented design, while the Atom's 9 lanes suit a low-power mobile platform.

The manufacturing processes also point to different design goals. The Atom's 10 nm node is smaller than the Threadripper's 14 nm node, which helps explain the Atom's dramatically lower TDP. The Threadripper compensates with higher clocks, more cores, and a wider memory interface, all of which contribute to its benchmark dominance.

Where Each One Wins

The AMD Ryzen Threadripper 1920X wins every category where both CPUs have recorded benchmark scores. In multi-threaded workloads, it is 82 percent ahead of the Atom across Cinebench R15, R20, and R23. In single-threaded workloads, the margin is identical, 82 percent in R20 and R23. For rendering, content creation, multithreaded compilation, or any task that scales with cores and threads, the Threadripper is the clear choice. Its 24 threads and 32 MB of L3 cache provide the resources needed for heavy parallel workloads.

The Intel Atom x7433RE wins in the areas that are not captured by the shared benchmarks. Its 9 watt TDP makes it suitable for low-power, fanless, or battery-powered designs. The integrated UHD Graphics 32EU removes the need for a separate GPU in basic display applications. The single-channel memory support and Gen 3 PCIe with 9 lanes are consistent with a compact, efficient mobile platform. The Atom's PassMark results, such as 43671 in data compression and 13054 in integer math, show it is not without capability in specific lightweight tasks.

For a buyer choosing between these two, the decision hinges on the use case. The Threadripper 1920X is for users who need maximum compute throughput and have the power budget and platform requirements to support it. The Atom x7433RE is for users who prioritize power efficiency, integrated graphics, and a mobile form factor. Benchmark data does not show a scenario where the Atom outperforms the Threadripper, but the Atom's design goals are orthogonal to raw performance. Each processor wins in the context it was built for: the Threadripper for computational muscle, the Atom for efficiency and integration.
