AMD Instinct MI455X vs NVIDIA GeForce RTX 4060 AD106 Comparison

Head-to-Head Benchmarks

The database currently holds no head-to-head benchmark results for the AMD Instinct MI455X versus the NVIDIA GeForce RTX 4060 AD106. Both entries show an average benchmark score of zero, and the head-to-head comparison array is empty. Each part carries a percentile rank of 50 among all GPUs, which places them at the median of the recorded distribution, but this is a default value rather than a measured outcome. The absence of recorded scores means there are no exact deltas, no win counts (winsA and winsB are both zero), and no nearest rival data to draw from. The data confirms a comparison that has not been populated with quantitative results. What can be examined are the raw architectural parameters that would govern performance if a test suite were run. The MI455X lists 32,768 shading units against 3,072 for the RTX 4060, a 10.7 times difference in raw shader count. FP32 throughput is 157.3 TFLOPS versus 15.11 TFLOPS, a 10.4 times advantage. Texture rate is 2,457.6 GTexel/s versus 236.2 GTexel/s, a 10.4 times gap. The MI455X has no pixel rate recorded (0 MPixel/s), while the RTX 4060 delivers 118.1 GPixel/s. Memory bandwidth is 23.3 TB/s versus 272.0 GB/s, an 85.7 times difference. These are specification-level comparisons, not measured benchmark scores.

Where Each One Wins

Without benchmark records, the wins must be inferred from the specification fields. The MI455X dominates compute-heavy workloads. Its FP32 and FP16 figures are identical at 157.3 TFLOPS, indicating a 1:1 ratio, which suits workloads that do not rely on reduced-precision acceleration. The 432 GB of HBM4 memory with a 24,576 bit bus width provides a capacity and bandwidth profile that the RTX 4060 cannot approach. The RTX 4060, by contrast, is the only one of the two with display outputs (1x HDMI 2.1 and 3x DisplayPort 1.4a), a defined pixel rate of 118.1 GPixel/s, and API support including DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The MI455X lists N/A for DirectX, OpenGL, and Vulkan. The RTX 4060 also includes 24 RT cores and 96 tensor cores, features that are recorded as null on the MI455X. The MI455X is a compute module with no outputs, while the RTX 4060 is a consumer graphics card with rendering and display capability. Each wins in its intended domain: the MI455X for massive parallel compute and memory-bound tasks, the RTX 4060 for rasterization, ray tracing, and display output.

Architecture Differences

The two chips come from different architectural lineages. The MI455X uses the CDNA 5.0 architecture and is built on the MI450 256CU chip. The RTX 4060 uses Ada Lovelace and the AD106 chip. Process nodes differ: the MI455X is on a 2 nm process, the RTX 4060 on 5 nm. Both are fabricated by TSMC. Transistor counts are far apart: 320,000 million for the MI455X against 22,900 million for the RTX 4060. Die size is 2990 mm² versus 188 mm². Transistor density is 107.0M per mm² for the MI455X and 121.8M per mm² for the RTX 4060, meaning the smaller chip packs transistors more densely. The MI455X belongs to the Instinct (MIx) generation with a Radeon Instinct predecessor. The RTX 4060 is part of the GeForce 40-series with a GeForce 30 predecessor and a GeForce 50 successor. Clock behavior differs. The MI455X has a base clock of 1000 MHz and boost of 2400 MHz. The RTX 4060 has a base of 1830 MHz and boost of 2460 MHz. Memory clocks are 1900 MHz (7.6 Gbps effective) for the MI455X and 2125 MHz (17 Gbps effective) for the RTX 4060. The memory types are HBM4 and GDDR6. Bus widths are 24,576 bit and 128 bit. The MI455X uses a PCIe 6.0 x16 interface, the RTX 4060 uses PCIe 4.0 x8. Power delivery is a major split. The MI455X has a TDP of 2300 W, no power connectors (it is an EAM Module), and a suggested PSU of 2700 W. The RTX 4060 has a TDP of 115 W, a single 12-pin connector, and a suggested PSU of 300 W. The MI455X is a dual-slot card in the RTX 4060 case, while the MI455X is an EAM Module form factor.

The Verdict

The data defines two different products. The MI455X is a compute module with no display outputs, no consumer API support, and an enormous memory and compute profile. It presents 157.3 TFLOPS of FP32, 432 GB of HBM4, and 23.3 TB/s of bandwidth. The RTX 4060 is a consumer graphics card with 15.11 TFLOPS, 8 GB of GDDR6, 272.0 GB/s, and full display and API support. The RTX 4060 is the only one with RT cores, tensor cores, a pixel rate, and a defined production status. The MI455X has a much higher TDP of 2300 W against 115 W, and a suggested PSU of 2700 W against 300 W. The release dates are separated by over two years, with the MI455X dated 2026-07-22 and the RTX 4060 dated 2024-03-31. The MI455X uses a newer process node at 2 nm, while the RTX 4060 uses 5 nm. The MI455X has no successor recorded; the RTX 4060 has a GeForce 50 successor. The MI455X is positioned for tasks that require massive parallel throughput and memory capacity, while the RTX 4060 is positioned for rendering and display-oriented workloads. The absence of benchmark scores means the database cannot yet rank them by measured performance. The specification records indicate that anyone choosing between them must decide based on compute scale versus consumer feature set. The MI455X is the compute-oriented choice; the RTX 4060 is the graphics-oriented choice.
