AMD Ryzen 9 7900X3D vs AMD Ryzen AI 5 440G Comparison

The AMD Ryzen AI 5 440G and the AMD Ryzen 9 7900X3D are both modern desktop processors on the AMD Socket AM5 platform, yet they serve completely different purposes. The recorded benchmark data shows a decisive split: the Ryzen 9 7900X3D wins every single head-to-head test in the database, while the Ryzen AI 5 440G offers a lower-power, integrated-graphics-focused alternative. The 7900X3D is a high-core-count, high-cache processor aimed at maximum throughput, while the 440G is a more modest six-core part with a modern integrated GPU. This analysis breaks down where each processor wins, what separates them architecturally, and what the raw numbers mean for real-world workloads.

Where Each One Wins

The benchmark results are unambiguous: the AMD Ryzen 9 7900X3D wins all 11 recorded head-to-head comparisons. Its dominance is most pronounced in multi-threaded and compute-heavy tasks. In PassMark's multithread test, the 7900X3D scores 50,317 against the 440G's 23,487, a 53.3% advantage. This pattern repeats across data compression, encryption, and physics simulations. The 7900X3D's 12 cores and 24 threads simply outmuscle the 440G's 6 cores and 12 threads in any workload that scales with core count.

The Ryzen AI 5 440G finds its niche not in raw performance but in efficiency and integrated graphics. Its 65-watt TDP is less than a third of the headroom required by the 7900X3D, which is rated at 120 watts. The 440G also features the Radeon 840M integrated graphics, a more capable iGPU than the generic Radeon Graphics on the 7900X3D. For systems that need basic graphics output without a discrete GPU, the 440G is the more sensible choice, though the database does not include GPU-specific benchmarks to quantify this advantage.

In single-thread performance, the gap narrows dramatically. The 7900X3D scores 4,126 in PassMark single-thread versus 4,060 for the 440G, a mere 1.6% difference. This indicates that for lightly threaded tasks like everyday productivity, web browsing, or older games, the two processors are nearly indistinguishable. The 440G's Zen 5 architecture appears to close the per-core gap with the 7900X3D's Zen 4 design, even though the latter has a higher boost clock of 5.60 GHz versus 4.80 GHz.

Architecture Differences

The two processors come from different generations and use different manufacturing processes. The Ryzen AI 5 440G is based on the Gorgon Point codename, part of the Ryzen AI 400 generation that mixes Zen 5 and Zen 5c cores. It is built on TSMC's 4 nm process node. The Ryzen 9 7900X3D uses the older Zen 4 architecture, codenamed Raphael, and is manufactured on TSMC's 5 nm node. This process difference partially explains why the 440G achieves competitive single-thread scores despite a lower boost clock.

Cache configuration is where the 7900X3D asserts its biggest architectural advantage. The 440G has 80 KB of L1 cache per core, 1 MB of L2 per core, and a total of 8 MB of L3 cache. The 7900X3D, by contrast, has 64 KB of L1 per core, 1 MB of L2 per core, and a massive 128 MB of shared L3 cache, which includes a dedicated 64 MB 3D V-Cache slice. This additional cache is a primary reason for the 7900X3D's overwhelming lead in data-heavy workloads like compression and encryption, where larger caches reduce memory latency and improve throughput.

The memory subsystems also differ. Both support DDR5 and dual-channel memory, but the 440G has a higher rated memory bandwidth of 89.6 GB/s versus 83.2 GB/s for the 7900X3D. This is counterintuitive given the 7900X3D's performance advantage, but it reflects the newer memory controller on the 440G. PCIe connectivity is another differentiator: the 440G offers Gen 4 with 12 lanes from the CPU, while the 7900X3D provides Gen 5 with 24 lanes. For users with high-end GPUs or NVMe storage, the 7900X3D's newer PCIe standard is a clear advantage.

Head-to-Head Benchmarks

The largest margin in the head-to-head results is in PassMark's find prime numbers test. The 7900X3D scores 445 against the 440G's 90, a 79.8% advantage. This test is highly sensitive to both core count and cache, making it an ideal showcase for the 7900X3D's 12-core design and 128 MB L3 cache. Similarly, the physics test shows a 71.9% lead for the 7900X3D (4,728 versus 1,329), reflecting its superior multi-threaded compute capability.

Data encryption and compression follow the same trend. The 7900X3D scores 35,293 in encryption versus 13,585 for the 440G, a 61.5% gap. In data compression, the 7900X3D hits 593,838 versus 292,735, a 50.7% difference. These workloads are heavily dependent on cache size and memory bandwidth, both areas where the 7900X3D's 128 MB L3 cache and higher core count shine. The extended instructions test shows a 53.7% lead for the 7900X3D (44,567 versus 20,648), indicating better AVX and SIMD throughput.

The closest contest is in single-thread performance. The 7900X3D's score of 4,126 is only 1.6% higher than the 440G's 4,060 in both PassMark single-thread and singlethread tests. This suggests that for single-core workloads, the architectural improvements in the 440G's Zen 5 cores nearly offset the 7900X3D's higher boost clock. However, the 7900X3D still wins, and the margin, while small, is consistent across both recorded test variants.

Specification Differences

The specification sheet highlights several key differences between these two processors. Core and thread counts are the most obvious: the Ryzen AI 5 440G has 6 cores and 12 threads, while the Ryzen 9 7900X3D has 12 cores and 24 threads. This doubling of resources directly explains the multi-threaded benchmark gaps. Clock speeds also differ significantly, with the 440G running at a base of 2.00 GHz and boost of 4.80 GHz, compared to the 7900X3D's 4.40 GHz base and 5.60 GHz boost.

Power consumption is a major differentiator. The 440G is rated at 65 watts TDP, while the 7900X3D draws up to 120 watts. This nearly doubles the thermal and power requirements for the 7900X3D, making it a more demanding platform choice. The process node also differs: the 440G uses TSMC's 4 nm process, while the 7900X3D uses the 5 nm node. This newer process contributes to the 440G's efficiency and its ability to reach competitive single-thread scores despite lower clocks.

Cache and memory specifications show further divergence. The 440G has 80 KB L1 per core and 8 MB total L3, while the 7900X3D has 64 KB L1 per core and 128 MB shared L3 with a 64 MB 3D V-Cache slice. The 7900X3D also has a larger die size of 2x 71 mm², compared to the 440G's 195 mm², and it contains 17,840 million transistors. The 440G's memory bandwidth is higher at 89.6 GB/s versus 83.2 GB/s, and its PCIe implementation is older (Gen 4, 12 lanes) versus the 7900X3D's Gen 5, 24 lanes.
