AMD Athlon X4 970 vs AMD Ryzen Threadripper 2970WX Comparison

The AMD Athlon X4 970 and the AMD Ryzen Threadripper 2970WX occupy opposite ends of the desktop spectrum. The Athlon is a 4-core, 4-thread part built on the older Excavator architecture, while the Threadripper is a 24-core, 48-thread behemoth on Zen+. The benchmark data leaves no ambiguity: across every shared test, the Threadripper 2970WX delivers a complete sweep, with the Athlon X4 970 failing to secure a single win. The core-count disparity and architectural generation gap dominate every metric.

Head-to-Head Benchmarks

The most striking result comes from Cinebench R23 multi-core, where the Threadripper 2970WX scores 26,305 points against the Athlon X4 970's 3,081. This represents an 88.3% deficit for the Athlon, meaning the Threadripper is roughly 8.5 times faster in this heavily threaded workload. The delta is identical across all five head-to-head tests, which underscores how consistent the performance gap is regardless of the benchmark's threading model.

Single-core performance tells a similar story, though the margin is less extreme in absolute terms. In Cinebench R23 single-core, the Threadripper scores 3,713 while the Athlon manages 435, again an 88.3% difference. The Threadripper's higher boost clock of 4.20 GHz versus the Athlon's 4.00 GHz helps explain part of this, but the architectural advantage of Zen+ over Excavator is the primary factor. The same pattern appears in Cinebench R20 single-core: 1,559 for the Threadripper versus 182 for the Athlon, with the same 88.3% delta.

The multi-core results in Cinebench R15 and R20 reinforce the trend. In R15, the Threadripper posts 2,651 points to the Athlon's 310, and in R20 it reaches 11,048 versus 1,294. Both represent the identical 88.3% gap. These numbers are not close calls; they reflect a fundamental chasm in parallel processing capability. The 24-core Threadripper with 48 threads simply overwhelms the 4-core, 4-thread Athlon in every scenario the data captures.

Interestingly, the Athlon X4 970's nearest rivals include the Intel Core i3-1115G4 and AMD Athlon Silver 10, both with average scores within 0.1% of the Athlon's 6,850 avgBenchmarkScore. The Threadripper 2970WX, meanwhile, sits near the Intel Core i7-12700E, which trails it by 0.2%, and the Intel Xeon Gold 6154, which leads it by 0.6%. This contextualizes the head-to-head: the Athlon competes in entry-level territory, while the Threadripper trades blows with high-end workstation silicon.

Where Each One Wins

The data offers no scenario where the Athlon X4 970 outperforms the Threadripper 2970WX. Across the five head-to-head benchmarks, the Threadripper wins all of them, leaving the Athlon with zero wins. This is a categorical result, not a matter of workload nuance. The Athlon's 63rd percentile ranking versus the Threadripper's 62nd percentile is the only metric where the Athlon appears competitive, but that ranking reflects the broader CPU population, not direct performance.

For the Threadripper 2970WX, the wins are universal. It excels in both single-threaded and multi-threaded Cinebench tests, which suggests it is not merely a brute-force multi-core monster but also a capable single-thread performer. Its 4.20 GHz boost clock and Zen+ architecture deliver single-core scores that dwarf the Athlon's. The Threadripper also carries 64 MB of L3 cache and quad-channel DDR4 memory with 93.9 GB/s bandwidth, figures that support its dominance in memory-sensitive workloads, though the head-to-head data does not explicitly test those scenarios.

The Athlon X4 970 does have its own benchmark profile outside the head-to-head set. PassMark results show it scoring 6,049 in floating-point math, 19,174 in integer math, and 6,128 in random string sorting. It also achieves 62,454 in data compression and 1,146 in data encryption. These numbers indicate a functional entry-level desktop processor, but they are not compared against the Threadripper in the provided head-to-head data. The Threadripper's Geekbench scores of 7,195 multi-core and 1,236 single-core further cement its position, though the Athlon has no Geekbench entries for direct comparison.

In practical terms, the Threadripper 2970WX is the clear choice for any workload that scales with cores, threads, or memory bandwidth. The Athlon X4 970, with its 65W TDP and dual-channel memory, is suited for basic desktop tasks, but the data gives it no edge over the Threadripper in any measured category.

The Verdict

Benchmark results indicate that the AMD Ryzen Threadripper 2970WX is the superior processor in every head-to-head comparison. It wins all five Cinebench tests, each by an 88.3% margin over the Athlon X4 970. For users seeking maximum multi-threaded performance, the Threadripper's 24 cores and 48 threads deliver 26,305 in Cinebench R23 multi-core, a figure that places it in the same league as the Intel Core i7-12700E and Xeon Gold 6154. The Athlon X4 970, by contrast, scores 3,081 in the same test, aligning it with entry-level parts like the Intel Core i3-1115G4.

Who should pick the Athlon X4 970? The data suggests only those constrained by its 65W TDP and Socket AM4 platform, where the Threadripper's 250W TDP and Socket SP3r2 are not viable. The Athlon's 63rd percentile ranking, while slightly above the Threadripper's 62nd, does not translate into any direct performance advantage. It is a capable desktop processor for basic tasks, but it cannot match the Threadripper in any benchmark the data covers.

Who should pick the Threadripper 2970WX? Anyone running heavily threaded workloads — rendering, compilation, scientific computing — will find its 26,305 Cinebench R23 multi-core score transformative. Its 4.20 GHz boost clock also ensures respectable single-thread performance at 3,713 in the same test. The launch MSRP is $1299, and its unlocked multiplier adds flexibility for overclocking. The Threadripper is the definitive choice for performance, with the Athlon serving only as a low-power alternative.

Q: How do their average benchmark scores compare?

A: The Athlon X4 970 has an average benchmark score of 6,850, while the Threadripper 2970WX scores 6,760. They are nearly identical overall, despite the Threadripper's dominance in head-to-head tests.

Q: What is the memory bandwidth difference between the two?

A: The Athlon X4 970 supports dual-channel DDR4 with 38.4 GB/s bandwidth. The Threadripper 2970WX supports quad-channel DDR4 with 93.9 GB/s, roughly 2.4 times the bandwidth.

Q: Which processor has a higher boost clock?

A: The Threadripper 2970WX boosts to 4.20 GHz, while the Athlon X4 970 boosts to 4.00 GHz. The Threadripper's base clock is 3.00 GHz, lower than the Athlon's 3.80 GHz, but its boost advantage and architecture yield higher single-core scores.

Architecture Differences

The two processors belong to different architectural eras. The Athlon X4 970 uses the Excavator architecture on a 28 nm process node from GlobalFoundries, with a die size of 250 mm² and 3,100 million transistors. It has 320 KB of L1 cache and 2 MB of L2 cache, with no L3 cache at all. The Threadripper 2970WX, by contrast, uses Zen+ architecture on a 12 nm process node, also from GlobalFoundries, with a die size of 4x 213 mm² and 19,200 million transistors. It has 96 KB of L1 cache per core and 512 KB of L2 cache per core, plus 64 MB of shared L3 cache.

The cache hierarchy alone explains much of the performance difference. The Athlon's lack of L3 cache forces it to rely entirely on L2, while the Threadripper's 64 MB L3 cache provides a massive buffer for frequently accessed data. The process node shrink from 28 nm to 12 nm also contributes to higher clock speeds and better efficiency, despite the Threadripper's higher 250W TDP.

Memory support also diverges. The Athlon X4 970 runs dual-channel DDR4 with 38.4 GB/s bandwidth, while the Threadripper 2970WX runs quad-channel DDR4 with 93.9 GB/s. This bandwidth advantage is critical for multi-threaded workloads that saturate memory interfaces. PCIe lanes differ as well: the Athlon provides 8 Gen 3 lanes from the CPU, while the Threadripper provides 60 Gen 3 lanes, enabling far greater expansion for GPUs and NVMe storage.

The sockets are incompatible: the Athlon uses AMD Socket AM4, while the Threadripper uses AMD Socket SP3r2. The Threadripper also has an unlocked multiplier, allowing user overclocking, whereas the Athlon does not. The Threadripper's launch MSRP is $1299, while the Athlon has no listed launch MSRP. Both processors lack integrated graphics and ECC memory support, and both are marked as Active in production status. The Athlon was released on 2017-07-26, while the Threadripper followed on 2018-10-01, a gap that aligns with the architectural leap from Excavator to Zen+.
