Architecture Differences

The Intel Atom x7433RE and AMD Ryzen Threadripper 1920 represent opposite ends of the processor design spectrum. The Atom uses the Amston Lake architecture built on Intel's 10 nm process, while the Threadripper uses the original Zen architecture built on GlobalFoundries' 14 nm process.

The Atom is a 4-core, 4-thread design with no simultaneous multithreading. Its cache layout uses 96 KB of L1 per core, 2 MB of shared L2, and 6 MB of shared L3. The Threadripper is a 12-core, 24-thread design with simultaneous multithreading. Its cache layout uses 96 KB of L1 per core, 512 KB of L2 per core, and 32 MB of L3. The Threadripper's L3 cache totals more than five times the Atom's shared L3.

The manufacturing differences are substantial. Intel produces the Atom on a 10 nm node at its own foundry. AMD relies on GlobalFoundries for the Threadripper's 14 nm process, and the chip contains 9,600 million transistors across a die size of 2x 213 mm². The Atom's transistor count and die size are not recorded in the database.

The memory subsystem differs fundamentally. The Atom supports both DDR4 and DDR5 with a single-channel bus delivering 38.4 GB/s of bandwidth. The Threadripper supports only DDR4 but uses a quad-channel bus delivering 85.3 GB/s of bandwidth. The Threadripper's memory bandwidth is more than double the Atom's.

PCIe connectivity also diverges. The Atom exposes Gen 3 with 9 CPU lanes, while the Threadripper exposes Gen 3 with 60 CPU lanes. The Threadripper offers a significantly wider I/O path for expansion.

Integrated graphics separate the two as well. The Atom includes UHD Graphics 32EU, while the Threadripper has no integrated graphics. The Threadripper requires a discrete GPU, which is typical for high-end desktop processors.

The market positioning reflects the architectural intent. The Atom is a mobile segment processor with a 9 watt TDP, currently active in production. The Threadripper is a desktop segment processor with a 140 watt TDP and is end-of-life. The Atom's generation is listed as Atom (Gracemont), while the Threadripper's is Ryzen Threadripper (Zen (Whitehaven)).

The Threadripper has an unlocked multiplier, allowing overclocking, while the Atom's multiplier is locked. The Atom's release date is recorded as April 7, 2024, while the Threadripper's release date is not recorded in the database.

Head-to-Head Benchmarks

The head-to-head benchmark results are unambiguous: the AMD Ryzen Threadripper 1920 wins all five recorded comparisons. The Intel Atom x7433RE does not secure a single victory in these tests.

The Cinebench R15 multi-core test shows the Threadripper scoring 1,890 against the Atom's 356, a delta of 81.2%. This is the same relative gap seen across the Cinebench suite. In Cinebench R20 multi-core, the Threadripper scores 7,877 versus the Atom's 1,484, again an 81.2% difference. The Cinebench R23 multi-core test shows the Threadripper at 18,756 and the Atom at 3,535, maintaining the 81.2% gap.

Single-core results follow the same pattern. In Cinebench R20 single-core, the Threadripper scores 1,111 against the Atom's 209, an 81.2% delta. In Cinebench R23 single-core, the Threadripper scores 2,647 versus the Atom's 499, a slightly narrower 81.1% delta. These consistent margins indicate that the Threadripper's advantage is not workload-specific but reflects a fundamental performance difference.

The absence of PassMark results for the Threadripper in the head-to-head data limits comparison to Cinebench workloads. However, the Cinebench suite spans both single-threaded and multi-threaded rendering tasks, providing a representative view of computational throughput.

For context on the Atom's standalone performance, its average benchmark score of 5,601 places it just 0.1% behind the Intel Core i7-12700T and 0.2% behind the AMD Ryzen 7 PRO 3700, while running 0.3% ahead of the Intel Core i9-11900KB and 0.7% ahead of the Intel Celeron G6900. These nearby rivals demonstrate that the Atom's average score is competitive with older or lower-power mainstream desktop parts.

The Threadripper's average benchmark score of 5,425 places it 0.3% behind the Intel Xeon W-1290P and 0.8% behind the AMD EPYC 7351P, while running 1.5% ahead of the Intel Core i9-13900TE and 2.1% ahead of the Intel Core i9-10900KF. The Threadripper's average score is slightly lower than the Atom's, despite its massive lead in Cinebench, because the average includes different benchmark mixes.

Specification Differences

The database records several specification differences between the two processors. The Intel Atom x7433RE has 4 cores and 4 threads; the AMD Ryzen Threadripper 1920 has 12 cores and 24 threads. Base clocks are 1.50 GHz for the Atom and 3.20 GHz for the Threadripper. Boost clocks are 3.40 GHz for the Atom and 3.80 GHz for the Threadripper.

TDP differs dramatically: 9 watts for the Atom versus 140 watts for the Threadripper. The Atom uses the Intel BGA 1264 socket, while the Threadripper uses the AMD Socket SP3r2. The Atom's architecture is Amston Lake on a 10 nm process; the Threadripper's is Zen on a 14 nm process.

Cache configurations differ in L2 and L3. The Atom has 2 MB of shared L2 and 6 MB of shared L3. The Threadripper has 512 KB of L2 per core and 32 MB of L3. Both share the same 96 KB of L1 per core.

Memory support differs: the Atom supports DDR4 and DDR5 on a single-channel bus with 38.4 GB/s bandwidth; the Threadripper supports DDR4 on a quad-channel bus with 85.3 GB/s bandwidth. The Atom has PCIe Gen 3 with 9 lanes; the Threadripper has PCIe Gen 3 with 60 lanes.

The Atom includes UHD Graphics 32EU integrated graphics; the Threadripper has none. The Atom targets the mobile segment, while the Threadripper targets desktop. The Atom is active in production; the Threadripper is end-of-life. The Atom has a locked multiplier; the Threadripper has an unlocked multiplier.

The database records a launch MSRP of $63 for the Intel Atom x7433RE. No launch MSRP is recorded for the AMD Ryzen Threadripper 1920.

The Verdict

The data points to a clear conclusion for raw performance: the AMD Ryzen Threadripper 1920 is the overwhelmingly faster processor. Its 81.2% lead across all Cinebench multi-core tests and its 81.1% to 81.2% lead in single-core tests leave no ambiguity. Anyone selecting between these two for compute-heavy workloads should choose the Threadripper based on benchmark results alone.

However, the Intel Atom x7433RE tells a different story. Its 61st percentile ranking exceeds the Threadripper's 60th percentile, and its average benchmark score of 5,601 exceeds the Threadripper's 5,425. This counterintuitive result stems from the different benchmark sets recorded for each processor. The Atom's average includes PassMark workloads where it achieves scores like 43,671 in data compression and 13,054 in integer math, while the Threadripper's average relies solely on Cinebench results.

The Atom's 9 watt TDP versus the Threadripper's 140 watt TDP represents a 15-fold difference in power envelope. For thermally constrained or battery-powered environments, the Atom is the only reasonable choice. The Threadripper's 140 watt TDP demands substantial cooling and power delivery.

The Threadripper's 32 MB of L3 cache and 85.3 GB/s memory bandwidth support its multi-threaded performance. The Atom's 6 MB of L3 and 38.4 GB/s bandwidth reflect its efficiency-focused design. The Threadripper's quad-channel memory bus and 60 PCIe lanes make it suitable for memory-intensive and I/O-intensive workloads, while the Atom's single-channel bus and 9 lanes limit such use.

The production status differs as well. The Atom is active, meaning it remains available for new designs. The Threadripper is end-of-life, indicating it is no longer in active production. This factor matters for long-term availability.

Where Each One Wins

The AMD Ryzen Threadripper 1920 wins in every recorded head-to-head benchmark. Its Cinebench R15 multi-core score of 1,890 versus the Atom's 356, its Cinebench R20 multi-core score of 7,877 versus 1,484, and its Cinebench R23 multi-core score of 18,756 versus 3,535 all demonstrate decisive multi-threaded superiority. The Threadripper also wins single-core tests, with Cinebench R20 single-core at 1,111 versus 209 and Cinebench R23 single-core at 2,647 versus 499.

The Intel Atom x7433RE wins in efficiency and portability. Its 9 watt TDP allows deployment in compact, passively cooled or battery-powered systems where the Threadripper's 140 watt TDP would be impractical. The Atom's integrated UHD Graphics 32EU eliminates the need for a discrete GPU, while the Threadripper requires one. The Atom's support for DDR5 memory provides a modern memory path, and its active production status ensures ongoing availability.

For workloads like Cinebench rendering, the Threadripper dominates. For embedded or mobile applications where power draw is the primary constraint, the Atom's profile is unmatched by the Threadripper. The database shows no scenario where the Atom outperforms the Threadripper in raw compute, but the Atom's existence is justified by its radically lower power consumption and integrated graphics.

The PassMark results recorded for the Atom illustrate its strengths in specific tasks. Its data compression score of 43,671 and integer math score of 13,054 are strong figures for a 4-core part. Its floating point math score of 8,582 and random string sorting score of 5,399 show balanced general-purpose capability. These scores contribute to its 61st percentile ranking.

The Threadripper's nearest rivals include the Intel Xeon W-1290P at 0.3% higher average score and the AMD EPYC 7351P at 0.8% higher, while it leads the Intel Core i9-13900TE by 1.5% and the Intel Core i9-10900KF by 2.1%. The Atom's nearest rivals include the Intel Core i7-12700T at 0.1% higher and the AMD Ryzen 7 PRO 3700 at 0.2% higher, while it leads the Intel Core i9-11900KB by 0.3% and the Intel Celeron G6900 by 0.7%. These nearby comparisons contextualize each processor's standing in the broader market.
