AMD Instinct MI308X vs NVIDIA GeForce RTX 4060 Mobile Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the AMD Instinct MI308X and the NVIDIA GeForce RTX 4060 Mobile. The MI308X has no recorded benchmark scores, an average benchmark score of 0, and no nearest rivals listed. The RTX 4060 Mobile, by contrast, has a full suite of recorded measurements across multiple test suites.

The RTX 4060 Mobile delivers a PassMark G3D score of 17,469, a PassMark GPU Compute score of 6,816, and Geekbench OpenCL and Vulkan scores of 89,420 and 89,569 respectively. Its average benchmark score across all recorded tests is 22,729, placing it in the 67th percentile of all GPUs in the database. The MI308X sits at the 50th percentile with no actual measurements, so the data cannot confirm any performance advantage for the AMD accelerator in real-world workloads.

Looking at the RTX 4060 Mobile's nearest rivals, its average score of 22,729 puts it 0.7% behind the NVIDIA GeForce RTX 2080 (22,895), 0.8% ahead of the AMD Radeon RX 7700 XT (22,549), 1.3% behind the Intel Arc B580 (23,021), and 1.3% ahead of the NVIDIA GeForce RTX 5060 Mobile (22,435). These deltas are all within roughly one to one-and-a-half percent, indicating that the RTX 4060 Mobile trades blows with a tight cluster of desktop and mobile GPUs from previous and current generations.

The MI308X's theoretical specifications, however, are in a different category entirely. Its FP32 throughput is listed at 81.72 TFLOPS, its texture rate at 2,553.6 GTexel/s, and its memory bandwidth at 5.32 TB/s. The RTX 4060 Mobile delivers 11.61 TFLOPS FP32, 181.4 GTexel/s texture rate, and 256.0 GB/s memory bandwidth. The MI308X's compute throughput is roughly seven times higher on paper, and its memory bandwidth is over twenty times higher, but these are architectural specifications rather than measured benchmark results. Without recorded scores for the MI308X, the data cannot translate those specifications into comparative performance figures.

The Verdict

The data presents a clear split: the NVIDIA GeForce RTX 4060 Mobile is a measured, active product with a full benchmark record, while the AMD Instinct MI308X has no recorded performance data whatsoever. The RTX 4060 Mobile's 67th percentile ranking and average score of 22,729 indicate a mid-to-upper-tier mobile GPU that competes closely with the RTX 2080, RX 7700 XT, Arc B580, and RTX 5060 Mobile, all within roughly 1.3% of each other.

The MI308X is a different class of hardware. Its 192 GB of HBM3 memory, 8192-bit bus, 5.32 TB/s bandwidth, and 81.72 TFLOPS FP32 throughput position it as a compute accelerator, not a consumer graphics card. It has no display outputs, no DirectX, OpenGL, or Vulkan API support, and a 750 W TDP. The RTX 4060 Mobile, with 8 GB GDDR6, a 128-bit bus, 256.0 GB/s bandwidth, and 115 W TDP, is designed for portable devices with full graphics API support including DirectX 12 Ultimate and Vulkan 1.4.

For anyone selecting a GPU for a laptop, the RTX 4060 Mobile is the only viable option between these two, as the MI308X cannot render to a display. For compute workloads, the MI308X's specifications suggest far higher raw throughput, but the database contains zero benchmark results to confirm this. The verdict from the recorded data is that the RTX 4060 Mobile is a proven, benchmarked product, while the MI308X remains an unmeasured specification sheet.

Where Each One Wins

The RTX 4060 Mobile wins in every category where actual measurements exist. It has recorded scores in Geekbench OpenCL, Geekbench Vulkan, PassMark DirectX 10, DirectX 11, DirectX 12, DirectX 9, G2D, G3D, and GPU Compute tests. Its production status is listed as Active, it has a successor (GeForce 50 Mobile), and it supports a full range of graphics APIs. Its 115 W TDP and IGP slot width make it suitable for portable devices, and its display outputs are portable-device dependent. The MI308X has no benchmark scores, no production status, no successor, no API support, and no display outputs.

The MI308X wins on raw specification comparisons. It has more memory (192 GB versus 8 GB), a wider memory bus (8192 bit versus 128 bit), higher memory bandwidth (5.32 TB/s versus 256.0 GB/s), more shading units (19,456 versus 3,072), more TMUs (1,216 versus 96), higher FP32 throughput (81.72 TFLOPS versus 11.61 TFLOPS), higher FP16 throughput (81.72 TFLOPS versus 11.61 TFLOPS), a larger die (1017 mm² versus 159 mm²), and more transistors (153,000 million versus 18,900 million). Its base clock is lower (1000 MHz versus 1545 MHz), but its boost clock is higher (2100 MHz versus 1890 MHz).

The MI308X also has a higher transistor density (150.4M per mm² versus 118.9M per mm²), a wider bus interface (PCIe 5.0 x16 versus PCIe 4.0 x8), and a higher suggested PSU (1150 W versus none listed). The RTX 4060 Mobile has more ROPs (48 versus 0), dedicated ray tracing cores (24 versus none), and tensor cores (96 versus none), which the MI308X lacks entirely. The pixel rate for the MI308X is listed as 0 MPixel/s, while the RTX 4060 Mobile delivers 90.72 GPixel/s.
