AMD Athlon X4 970 vs Intel Core i9-10940X Comparison

The Verdict

The data in this comparison is unequivocal. The Intel Core i9-10940X outperforms the AMD Athlon X4 970 in every single recorded head-to-head benchmark, winning all five tests with a consistent margin of 86.9 percent. The Athlon X4 970 fails to claim a single victory across any of the tested workloads, making the Core i9-10940X the definitive choice for any application where raw processing power matters.

The AMD Athlon X4 970, despite its lower standing in raw performance, occupies a distinct position in the database. With an average benchmark score of 6850 and a percentile rank of 63 against all CPUs, it sits in a peculiar spot. Its nearest rivals include the Intel Core i3-1115G4, which scores nearly identically at 6851, and the AMD Athlon Silver 10 at 6849. The Intel Xeon W-2195 trails by 0.6 percent, while the Intel Xeon Gold 6154 leads by 0.7 percent. This places the Athlon X4 970 in a cluster of processors that offer modest, comparable performance for basic desktop tasks.

The Intel Core i9-10940X, meanwhile, records an average benchmark score of 6605 and a percentile rank of 62 against all CPUs. Its nearest rivals are notably different in character. The Intel Pentium Gold G6405 matches its score exactly, the Intel Core i9-12900E trails by 0.1 percent, the Intel Core i5-13500E leads by 0.3 percent, and the Intel Core i5-13400E leads by 0.5 percent. This suggests the Core i9-10940X, despite its massive multi-core advantage over the Athlon, operates in a performance tier where its average score is tempered by single-threaded limitations and the overall mix of workloads.

For users who need heavy multi-threaded computation, rendering, or content creation, the Core i9-10940X is the only rational pick based on the recorded data. For users who require a simple, low-power desktop processor for basic tasks, the Athlon X4 970 offers a viable, though far less capable, alternative. The choice is not about nuance; it is about the scale of the performance gap.

Architecture Differences

The two processors come from entirely different architectural lineages, which explains the vast performance disparity. The AMD Athlon X4 970 is built on the Excavator architecture, codenamed Bristol Ridge, using a 28 nm process node manufactured by GlobalFoundries. It integrates 3,100 million transistors on a 250 mm² die. The processor features 4 cores and 4 threads, with a base clock of 3.80 GHz and a boost clock of 4.00 GHz. Its cache hierarchy is modest, with 320 KB of L1 cache and 2 MB of L2 cache, and no L3 cache at all. It supports DDR4 memory through a dual-channel memory bus, delivering a memory bandwidth of 38.4 GB/s. The PCIe implementation is Gen 3 with only 8 lanes from the CPU, and the multiplier is locked.

The Intel Core i9-10940X is a fundamentally different beast. It belongs to the Core 10th Gen series, built on the Cascade Lake architecture, codenamed Cascade Lake-X, using a 14 nm process node fabricated by Intel. It houses 14 cores and 28 threads, with a base clock of 3.30 GHz and a boost clock of 4.80 GHz. The cache structure is more generous: 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 19.25 MB of shared L3 cache. Memory support includes DDR4 through a quad-channel memory bus, though the database does not record a bandwidth figure. The PCIe implementation is Gen 3 without lane specifics. The multiplier is unlocked, allowing overclocking.

The architectural chasm is evident in the process nodes and core counts. The Athlon's Excavator design is an older, smaller-scale architecture, while the Cascade Lake design is a high-end enthusiast platform. The Core i9-10940X also carries a significantly higher thermal design power at 165 watts compared to the Athlon's 65 watts, reflecting the substantial difference in compute resources and power delivery requirements.

Head-to-Head Benchmarks

The benchmark results paint a stark picture of dominance. In Cinebench R15 multi-core, the Intel Core i9-10940X scores 2370 against the AMD Athlon X4 970's 310, a difference of 86.9 percent. This is the first of several identical percentage margins, indicating a consistent scaling factor across workloads.

Cinebench R20 multi-core follows the same pattern. The Core i9-10940X achieves 9878, while the Athlon X4 970 manages only 1294, again a 86.9 percent deficit. The single-core R20 test further confirms the trend, with the Intel part scoring 1394 versus the AMD's 182, still a 86.9 percent gap.

Cinebench R23 multi-core shows the largest absolute difference in points. The Intel Core i9-10940X records 23520, while the AMD Athlon X4 970 posts 3081. The percentage difference remains 86.9 percent. In the single-core R23 test, the Intel processor scores 3320 against the Athlon's 435, maintaining the same 86.9 percent delta.

The consistency of the 86.9 percent margin across all five tests is remarkable. It suggests that the performance gap is not workload-specific but rather a fundamental throughput difference driven by the core count, thread count, and architectural efficiency. The Intel Core i9-10940X does not merely edge out the AMD Athlon X4 970; it obliterates it in every measured dimension. The Athlon's best result, a 3081 in Cinebench R23 multi-core, is less than a seventh of the Intel's 23520.

Specification Differences

The specification sheets reveal the structural reasons behind the benchmark results. The most glaring difference is in core and thread counts: the Intel Core i9-10940X offers 14 cores and 28 threads, while the AMD Athlon X4 970 offers 4 cores and 4 threads. This is a 10-core and 24-thread difference, which directly translates to the massive multi-threaded performance advantage.

Clock speeds differ in both directions. The AMD Athlon X4 970 has a higher base clock at 3.80 GHz compared to the Intel's 3.30 GHz, but the Intel part has a substantially higher boost clock at 4.80 GHz versus the Athlon's 4.00 GHz. The Intel processor's ability to reach nearly 5 GHz on boost gives it a significant single-threaded edge, as evidenced by the R23 single-core score of 3320 versus 435.

Thermal design power is another major differentiator. The Intel Core i9-10940X is rated at 165 watts, more than double the AMD Athlon X4 970's 65 watts. This reflects the Intel part's much larger power envelope and, consequently, its need for robust cooling solutions.

Sockets and platforms are entirely incompatible. The AMD Athlon X4 970 uses AMD Socket AM4, while the Intel Core i9-10940X uses Intel Socket 2066. The memory bus also diverges: the Athlon supports dual-channel memory, while the Intel part supports quad-channel, offering potentially greater memory bandwidth, though the database does not record a specific bandwidth figure for the Intel processor.

Cache configurations differ substantially. The Athlon has 320 KB of L1 and 2 MB of L2, with no L3. The Intel part has 64 KB of L1 per core, 1 MB of L2 per core, and 19.25 MB of shared L3. The per-core cache allocation on the Intel part is generous, contributing to its superior performance in both single and multi-threaded workloads.

The multiplier is locked on the AMD Athlon X4 970, while the Intel Core i9-10940X has an unlocked multiplier, enabling user-controlled overclocking. The AMD processor's part number is recorded as AD970XAUABBOXAD970XAUM44AB, while no part number is listed for the Intel processor.
