AMD Ryzen Threadripper 9980X vs Qualcomm Snapdragon X1E-84-100 Comparison

# Where Each One Wins

The recorded data presents a starkly lopsided comparison. The AMD Ryzen Threadripper 9980X holds every benchmark advantage in the database, with all 17 recorded test scores belonging to the AMD part. The Qualcomm Snapdragon X1E-84-100, by contrast, has no recorded benchmark scores in the database, leaving its performance profile entirely unquantified in direct comparison.

For heavily parallel workloads, the Threadripper 9980X is the clear victor. Its 64 cores and 128 threads deliver a Cinebench R23 multicore score of 130,529, a Cinebench R20 multicore score of 54,822, and a Cinebench R15 multicore score of 13,157. These figures place the chip in the 99th percentile among all CPUs in the database, indicating that it sits at the very top of the performance distribution for multi-threaded rendering and compute tasks.

The PassMark suite reinforces this pattern. The Threadripper 9980X scores 872,071 in integer math, 559,003 in floating point math, and 297,453 in data compression. Its multithread score of 141,641 and extended instructions score of 228,959 further demonstrate strength in sustained parallel execution. The single-thread results, while less dominant relative to the multicore numbers, are still substantial: a Cinebench R23 single-core score of 18,427 and a PassMark single-thread score of 4,537.

The Snapdragon X1E-84-100, in contrast, is a 12-core, 12-thread mobile processor with a base clock of 3.80 GHz and a boost clock of 4.20 GHz. Its lack of any recorded benchmark data means the database cannot confirm any specific workload where it wins over the Threadripper. The AMD part also leads in raw specifications that typically correlate with performance: a 5.40 GHz boost clock, 256 MB of L3 cache, and a 350 W TDP.

# The Verdict

The data indicates that the AMD Ryzen Threadripper 9980X is the appropriate choice for any user whose primary requirement is maximum multi-threaded throughput. Its 64 cores, 128 threads, and 99th percentile ranking among all CPUs in the database make it a top-tier part for rendering, scientific computing, and other heavily parallel tasks. The chip's average benchmark score of 321,753 dwarfs the Snapdragon's average score of 0, and the nearest rivals in the database, the AMD Ryzen Threadripper PRO 9985WX at 320,749 and the Intel Xeon 6781P at 315,524, trail by margins of 0.3% and 2% respectively.

The Qualcomm Snapdragon X1E-84-100, on the other hand, is a mobile processor with a 35 W TDP, a dual-channel LPDDR5X memory bus, and an integrated Adreno X1-85 GPU. Its 50th percentile ranking among all CPUs places it squarely in the middle of the performance distribution. Users who prioritize portability, integrated graphics, or low power consumption would find the Snapdragon suitable, but the database contains no benchmark data to support a claim of performance superiority in any workload.

For anyone building a desktop workstation or server with a focus on compute density, the Threadripper 9980X is the only defensible choice based on the recorded measurements. The Snapdragon's lack of benchmark data in the database means no performance-based recommendation can be made for it.

# Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two processors, so direct comparisons must be drawn from the Threadripper 9980X's individual scores and the Snapdragon's complete absence of recorded results.

The Threadripper 9980X's Cinebench R23 multicore score of 130,529 represents its strongest single data point. For context, its nearest rival, the AMD Ryzen Threadripper PRO 9985WX, has an average benchmark score of 320,749, just 0.3% behind the 9980X's 321,753 average. The Intel Xeon 6781P trails by 2% with an average of 315,524, and the AMD EPYC 9575F and EPYC 9734 sit at 3.2% and 3.6% behind respectively.

In the PassMark suite, the Threadripper 9980X shows particular strength in integer math with a score of 872,071, and in floating point math with 559,003. Its data encryption score of 157,137 and find prime numbers score of 769 round out a comprehensive parallel workload profile. The single-thread performance, while less extraordinary, still delivers a Cinebench R23 single-core score of 18,427 and a PassMark single-thread score of 4,537.

The Snapdragon X1E-84-100 has zero recorded benchmarks in the database. Its 12 cores and 12 threads, combined with a 3.80 GHz base and 4.20 GHz boost clock, suggest a design aimed at efficiency rather than peak throughput. Its 50th percentile ranking among all CPUs indicates it sits near the median, but no concrete score exists to quantify its performance in any specific test.

# Architecture Differences

The two processors represent fundamentally different design philosophies. The AMD Ryzen Threadripper 9980X is built on the Zen 5 architecture with the Shimada Peak codename, part of the 9000 series and the Ryzen Threadripper generation. It uses a 4 nm process from TSMC, containing 66,520 million transistors spread across 8x 70.6 mm² dies. The Snapdragon X1E-84-100, by contrast, uses the Oryon codename and is part of the Snapdragon X (Elite) generation, also fabricated on a 4 nm TSMC process, though its transistor count and die size are not recorded.

Memory architecture differs significantly. The Threadripper 9980X uses a quad-channel DDR5 bus with 204.8 GB/s of bandwidth and supports ECC memory, making it suitable for error-sensitive workloads like data centers and professional computing. The Snapdragon X1E-84-100 uses a dual-channel LPDDR5X bus with 135.2 GB/s of bandwidth and lacks ECC support, reflecting its mobile orientation.

PCIe connectivity also sets them apart. The Threadripper 9980X offers Gen 5 with 80 lanes from the CPU alone, while the Snapdragon X1E-84-100 provides Gen 4 with 12 lanes. This difference in expansion capability is substantial for workstation users who need multiple GPUs, NVMe storage, or high-speed networking.

The Threadripper 9980X has an unlocked multiplier, enabling overclocking, while the Snapdragon's multiplier is locked. The Threadripper also has a substantially higher TDP at 350 W versus 35 W for the Snapdragon, which correlates with its higher core count and clock speeds. The Snapdragon includes an integrated Adreno X1-85 GPU, while the Threadripper has no integrated graphics.

The Threadripper 9980X was released on 2025-07-29 with a launch MSRP of $4999, while the Snapdragon X1E-84-100 was released on 2024-04-23 with no launch MSRP recorded. The Threadripper's part number is 100-000001593, and the Snapdragon's is X1E84100.
