AMD Instinct MI455X vs NVIDIA GeForce RTX 4060 Mobile Comparison

Head-to-Head Benchmarks

The recorded database contains no head-to-head benchmark comparisons between the AMD Instinct MI455X and the NVIDIA GeForce RTX 4060 Mobile. The head-to-head field is empty, and the AMD part has no benchmark scores, no average score, and no nearest rivals listed. The NVIDIA part, by contrast, has nine recorded benchmark results and a full rival profile.

The AMD Instinct MI455X carries an average benchmark score of zero and a percentile rank of 50 among all GPUs. The NVIDIA GeForce RTX 4060 Mobile carries an average benchmark score of 22,729 and a percentile rank of 67. In the absence of shared test data, the only numerical comparison available is the aggregate score gap: the RTX 4060 Mobile records 22,729 points against zero for the MI455X in the database.

The RTX 4060 Mobile's individual results show a wide spread across test types. Its strongest single score is in Geekbench Vulkan at 89,569, marginally ahead of its Geekbench OpenCL result of 89,420. The PassMark G3D score sits at 17,469, while PassMark GPU Compute lands at 6,816. Legacy DirectX tests are far lower: PassMark DirectX 12 scores 73, DirectX 11 scores 157, DirectX 10 scores 107, and DirectX 9 scores 216. The PassMark G2D score is 730.

The rival comparison for the RTX 4060 Mobile places it within a tight cluster. The NVIDIA GeForce RTX 2080 averages 22,895, which is 0.7% higher than the RTX 4060 Mobile. The Intel Arc B580 averages 23,021, 1.3% higher. The AMD Radeon RX 7700 XT averages 22,549, 0.8% lower, and the NVIDIA GeForce RTX 5060 Mobile averages 22,435, 1.3% lower. These deltas indicate the RTX 4060 Mobile sits in a narrow band where no nearby rival is more than 1.3 points percentage away in either direction.

The MI455X, having no benchmark data, cannot be placed in any rival ranking. Its percentile rank of 50 is a database default rather than a measured outcome. The data cannot show whether the MI455X would outperform or trail the RTX 4060 Mobile in any workload.

The Verdict

Strictly from recorded data, the NVIDIA GeForce RTX 4060 Mobile is the only part with any measurable performance information. It has nine benchmark scores, an average of 22,729, and a percentile rank of 67. The AMD Instinct MI455X has zero benchmark scores, an average of zero, and a percentile rank of 50. Anyone selecting between these two based on the database would have no evidence of MI455X performance to weigh.

The RTX 4060 Mobile's nearest rival data shows it performs within 1.3% of several established GPUs, including the RTX 2080, RX 7700 XT, and Arc B580. That positions it as a mid-pack mobile GPU in this database's ranking. The MI455X has no such positioning.

The MI455X is an accelerator with a 2,300 W TDP and no display outputs, while the RTX 4060 Mobile is an integrated graphics processor for portable devices with a 115 W TDP. The data shows they target different product categories entirely. The verdict from the database is straightforward: the RTX 4060 Mobile has a measured performance profile, the MI455X does not, and no head-to-head conclusion can be drawn.

Where Each One Wins

The data supports only one clear winner on measured performance: the NVIDIA GeForce RTX 4060 Mobile. It has all nine recorded benchmark scores, an average of 22,729, and a 67th percentile rank. Its nearest rival data shows it within 1.3% of the RTX 2080, the Arc B580, the RX 7700 XT, and the RTX 5060 Mobile. For any workload represented by the recorded tests, including Geekbench OpenCL, Geekbench Vulkan, PassMark G3D, and PassMark GPU Compute, the RTX 4060 Mobile has measurable results.

The AMD Instinct MI455X wins on raw specification counts. It has more shading units, more TMUs, more memory, wider memory bus, higher memory bandwidth, higher FP32 and FP16 throughput, higher texture rate, higher transistor count, and larger die size. It also has a higher boost clock at 2,400 MHz versus 1,890 MHz. Its TDP of 2,300 W and suggested PSU of 2,700 W indicate a power envelope far beyond the RTX 4060 Mobile's 115 W.

The MI455X has a newer process node at 2 nm versus 5 nm, a newer bus interface at PCIe 6.0 x16 versus PCIe 4.0 x8, and a later release date of 2026-07-22 versus 2023-01-02. The RTX 4060 Mobile wins on transistor density, pixel rate, ROP count, RT core count, tensor core count, API support, and the presence of display outputs.

The database cannot assign workload-specific wins to the MI455X because it has no benchmark scores. The RTX 4060 Mobile wins every measured category by default. The MI455X wins every specification category where it has a listed value, except transistor density, pixel rate, and memory clock, where the RTX 4060 Mobile leads.
