Architecture Differences

The two GPUs diverge sharply in design intent. The AMD Instinct MI325X uses the CDNA 3.0 architecture, a compute-optimized design with no display outputs. Its chip, Aqua Vanjaram, houses 153,000 million transistors on a 1017 mm² die, giving a transistor density of 150.4M per mm². The NVIDIA GeForce RTX 4060 Mobile uses Ada Lovelace, a graphics-focused architecture with 18,900 million transistors on a 159 mm² die, resulting in a lower density of 118.9M per mm².

Shading unit counts reflect the compute versus graphics split. The MI325X has 19,456 shading units, 1,216 TMUs, and no ROPs, pixel rate, or ray tracing cores. The RTX 4060 Mobile has 3,072 shading units, 96 TMUs, 48 ROPs, 24 ray tracing cores, and 96 tensor cores. The RTX 4060 Mobile also reports a pixel rate of 90.72 GPixel/s, while the MI325X reports 0 MPixel/s.

Memory architecture differs fundamentally. The MI325X uses 256 GB of HBM3e across an 8192-bit bus for 6.14 TB/s bandwidth. The RTX 4060 Mobile uses 8 GB of GDDR6 across a 128-bit bus for 256.0 GB/s. Clock behavior also differs: the MI325X operates at a 1000 MHz base and 2100 MHz boost, while the RTX 4060 Mobile has a higher base of 1545 MHz and a boost of 1890 MHz. The MI325X memory clock is listed at 1500 MHz with 6 Gbps effective, whereas the RTX 4060 Mobile memory runs at 2000 MHz with 16 Gbps effective.

Interface and form factor separate them further. The MI325X is an OAM module with PCIe 5.0 x16 and no power connectors, while the RTX 4060 Mobile is an IGP with PCIe 4.0 x8 and portable-device-dependent display outputs. The MI325X does not list DirectX, OpenGL, or Vulkan support, while the RTX 4060 Mobile supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Where Each One Wins

The AMD Instinct MI325X wins outright in raw compute workloads. Its FP32 rating of 81.72 TFLOPS is roughly seven times the 11.61 TFLOPS of the RTX 4060 Mobile. The texture rate also favors the MI325X at 2,553.6 GTexel/s versus 181.4 GTexel/s for the RTX 4060 Mobile. Memory bandwidth is another decisive area: 6.14 TB/s versus 256.0 GB/s, a factor of roughly 24. The MI325X also carries 256 GB of memory against 8 GB, making it suited for large datasets that cannot fit in the smaller frame buffer.

The NVIDIA GeForce RTX 4060 Mobile wins in graphics-specific features. It has ray tracing cores and tensor cores, which the MI325X lacks entirely. It also has a functional pixel rate of 90.72 GPixel/s, while the MI325X reports 0. The RTX 4060 Mobile supports full graphics API stacks, including DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, whereas the MI325X lists none. Its portable form factor and lower TDP of 115 W make it applicable to systems where the 1000 W OAM module cannot operate.

Benchmark data exists only for the RTX 4060 Mobile. Its recorded scores include Geekbench OpenCL at 89,420, Geekbench Vulkan at 89,569, Passmark G3D at 17,469, Passmark G2D at 730, and Passmark GPU Compute at 6,816. The MI325X has no benchmark entries, no average score, and no rival comparisons in the database, so direct measured results cannot be compared.

Head-to-Head Benchmarks

The database contains no shared benchmark entries between the two GPUs. The MI325X has an empty benchmark list, an average score of 0, and a percentile of 50 among all GPUs. The RTX 4060 Mobile has a full benchmark suite, an average score of 22,729, and a percentile of 67.

Because no head-to-head results are recorded, the comparison must rely on specification-driven measurements. The FP32 gap is the clearest: 81.72 TFLOPS for the MI325X versus 11.61 TFLOPS for the RTX 4060 Mobile, a difference of roughly 70 TFLOPS in favor of AMD. Memory bandwidth shows a larger relative gap, with 6.14 TB/s versus 256.0 GB/s. Texture rate favors the MI325X by a factor of roughly 14, while pixel rate favors the RTX 4060 Mobile exclusively since the MI325X reports zero.

For the RTX 4060 Mobile, nearest rival data provides context for its measured performance. It scores 0.8% higher than the AMD Radeon RX 7700 XT and 1.3% higher than the NVIDIA GeForce RTX 5060 Mobile. It trails the NVIDIA GeForce RTX 2080 by 0.7% and the Intel Arc B580 by 1.3%. These deltas place the RTX 4060 Mobile in a tight band around the 22,500 to 23,000 average score range. The MI325X has no nearest rivals listed, so no analogous positioning exists.

The absence of measured scores for the MI325X means its percentile of 50 is not derived from actual benchmark runs. The RTX 4060 Mobile, by contrast, has measured results that support its 67th percentile ranking. The recorded Geekbench scores of 89,420 for OpenCL and 89,569 for Vulkan indicate strong general compute performance for a mobile GPU, while Passmark G3D at 17,469 and GPU Compute at 6,816 show its graphics and compute split.

The Verdict

The data describes two GPUs with almost no functional overlap. The AMD Instinct MI325X is a compute accelerator with 256 GB of HBM3e, 81.72 TFLOPS of FP32, and a 1000 W TDP. It has no display outputs, no graphics API support, and no measured benchmarks in the database. Its role is defined by its memory capacity, bandwidth, and compute throughput, all of which exceed the RTX 4060 Mobile by wide margins.

The NVIDIA GeForce RTX 4060 Mobile is a graphics processor for portable devices. It has ray tracing cores, tensor cores, a 90.72 GPixel/s pixel rate, and full DirectX, OpenGL, and Vulkan support. Its measured average benchmark score of 22,729 and 67th percentile ranking place it among capable mobile GPUs, with rival deltas ranging from -1.3% to +1.3% against desktop and mobile cards.

Selection depends on workload. For large-scale compute tasks that fit within a 256 GB memory pool and require 6.14 TB/s of bandwidth, the MI325X is the only option of the two. For graphics rendering, ray tracing, or any display-connected use case, the RTX 4060 Mobile is the functional choice. The MI325X cannot output video and does not support standard graphics APIs. The RTX 4060 Mobile cannot approach the MI325X in memory capacity or raw FP32 throughput. The recorded data shows no scenario where one replaces the other.
