AMD Instinct MI300A vs NVIDIA GeForce RTX 4060 Mobile Comparison

# AMD Instinct MI300A vs NVIDIA GeForce RTX 4060 Mobile

The AMD Instinct MI300A and NVIDIA GeForce RTX 4060 Mobile occupy entirely different segments of the GPU market, and their recorded specifications reflect that divide. The MI300A is an OAM module designed for compute acceleration, while the RTX 4060 Mobile is an integrated graphics processor for laptops. The MI300A holds a percentile rank of 50 among all GPUs in the database, whereas the RTX 4060 Mobile sits at percentile 67. However, no direct head-to-head benchmark results exist between these two products, so comparisons must be drawn from their architectural specifications and the RTX 4060 Mobile's recorded average benchmark score.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between the AMD Instinct MI300A and the NVIDIA GeForce RTX 4060 Mobile. The MI300A has no recorded benchmarks and an average benchmark score of zero, while the RTX 4060 Mobile has an average benchmark score of 22,729 across nine tests. This absence of direct measurement data means the comparison relies on the documented specifications of each part.

The RTX 4060 Mobile's benchmark suite provides a clear picture of its performance profile. In Geekbench OpenCL, it scores 89,420, and in Geekbench Vulkan it scores 89,569. Passmark results show a G3D score of 17,469 and a GPU compute score of 6,816. The DirectX tests range from 73 in DirectX 12 to 216 in DirectX 9, with DirectX 10 at 107 and DirectX 11 at 157. The G2D score is 730. These numbers place the RTX 4060 Mobile close to several desktop rivals: it trails the NVIDIA GeForce RTX 2080 by 0.7 percent, trails the Intel Arc B580 by 1.3 percent, and leads the AMD Radeon RX 7700 XT by 0.8 percent and the NVIDIA GeForce RTX 5060 Mobile by 1.3 percent.

The MI300A, by contrast, has no benchmark scores in the database. Its specifications, however, indicate a compute-oriented design. The FP32 throughput is listed at 61.29 TFLOPS, which is roughly 5.3 times the RTX 4060 Mobile's 11.61 TFLOPS. Texture rate for the MI300A is 1,915.2 GTexel/s compared to 181.4 GTexel/s for the RTX 4060 Mobile, a factor of about 10.6. The MI300A's pixel rate is listed as 0 MPixel/s, reflecting its lack of display outputs, while the RTX 4060 Mobile delivers 90.72 GPixel/s. These numbers indicate that the MI300A is not designed for rasterization workloads in the traditional sense, but for massive parallel compute.

Architecture Differences

The AMD Instinct MI300A uses the CDNA 3.0 architecture on a chip named Aqua Vanjaram, manufactured on a 5 nm process by TSMC. The NVIDIA GeForce RTX 4060 Mobile uses the Ada Lovelace architecture on the AD107 chip, also manufactured on a 5 nm process by TSMC. Both share the same process node and foundry, but the similarities end there.

The MI300A is built for data center compute. Its 153,000 million transistors are packed into a 1017 mm² die, yielding a transistor density of 150.4 million per square millimeter. The RTX 4060 Mobile's 18,900 million transistors occupy a 159 mm² die, for a density of 118.9 million per square millimeter. The MI300A is a massive chip by any measure, over six times the die area of the RTX 4060 Mobile.

Memory architecture differs fundamentally. The MI300A uses 128 GB of HBM3 across an 8192-bit bus, achieving 5.32 TB/s bandwidth. The RTX 4060 Mobile uses 8 GB of GDDR6 across a 128-bit bus, achieving 256.0 GB/s. The MI300A's memory system is built for bandwidth-intensive workloads such as large model inference and high-performance computing, while the RTX 4060 Mobile's smaller memory pool suits consumer graphics and gaming.

Clock behavior also diverges. The MI300A has a base clock of 1000 MHz and a boost clock of 2100 MHz, with memory clocked at 1300 MHz (5.2 Gbps effective). The RTX 4060 Mobile has a higher base clock of 1545 MHz and a boost clock of 1890 MHz, with memory at 2000 MHz (16 Gbps effective). Despite the RTX 4060 Mobile's higher base clock, the MI300A's massive shading unit count drives its FP32 throughput to 61.29 TFLOPS versus 11.61 TFLOPS for the RTX 4060 Mobile.

The RTX 4060 Mobile includes 24 ray tracing cores and 96 tensor cores, features absent from the MI300A's specification list. The MI300A has 912 texture mapping units and 0 ROPs, while the RTX 4060 Mobile has 96 TMUs and 48 ROPs. The MI300A's texture rate of 1,915.2 GTexel/s dwarfs the RTX 4060 Mobile's 181.4 GTexel/s, but the RTX 4060 Mobile can output pixels at 90.72 GPixel/s while the MI300A manages 0 MPixel/s. The MI300A has no display outputs, while the RTX 4060 Mobile's outputs are portable device dependent.

The Verdict

The data describes two devices with no overlapping use cases. The AMD Instinct MI300A is an OAM module with a 750 W TDP, 128 GB of HBM3, and no display outputs. It is designed for compute environments where massive memory bandwidth and FP32 throughput matter. Its 61.29 TFLOPS FP32 and 5.32 TB/s memory bandwidth place it in a category optimized for data center acceleration, not conventional graphics.

The NVIDIA GeForce RTX 4060 Mobile is an integrated GPU for laptops with a 115 W TDP, 8 GB of GDDR6, and full graphics API support including DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. Its benchmark scores show it performing within 1.3 percent of desktop cards like the RTX 2080 and Arc B580, and within 0.8 percent of the RX 7700 XT. It is a capable mobile graphics solution with ray tracing and tensor cores.

Users seeking a laptop graphics processor should select the RTX 4060 Mobile, as the MI300A cannot output to displays and lacks consumer API support. Users building compute nodes requiring high FP32 throughput and enormous memory capacity would choose the MI300A, as its specifications exceed the RTX 4060 Mobile by factors of 5 to 20 in compute, memory, and bandwidth metrics. The RTX 4060 Mobile's percentile rank of 67 indicates it outperforms most GPUs in the database, while the MI300A's rank of 50 reflects its lack of recorded benchmark data rather than its compute potential.
