AMD Instinct MI308X vs NVIDIA GeForce RTX 4060 Comparison

The Verdict

The AMD Instinct MI308X and NVIDIA GeForce RTX 4060 serve entirely different segments of the GPU market. The MI308X is an accelerator with no display outputs, no consumer graphics API support, and a 750 W power envelope, built for compute workloads. The RTX 4060 is an end-of-life consumer graphics card with a 115 W TDP, display outputs, and full DirectX 12 Ultimate support. The data shows the MI308X has no benchmark scores recorded in the database, while the RTX 4060 has ten recorded benchmarks. The MI308X sits at the 50th percentile among all GPUs, while the RTX 4060 sits at the 61st percentile. For anyone requiring rasterization, ray tracing, or standard graphics APIs, the RTX 4060 is the only option with recorded data. For large-scale compute tasks, the MI308X offers 192 GB of HBM3 memory and 81.72 TFLOPS of FP32 throughput, numbers that dwarf the RTX 4060's 8 GB GDDR6 and 15.11 TFLOPS. The choice depends entirely on workload: the RTX 4060 for conventional graphics and gaming, the MI308X for memory-intensive or massively parallel compute.

Architecture Differences

The MI308X uses the Aqua Vanjaram chip on the CDNA 3.0 architecture, fabricated on a 5 nm process at TSMC. It contains 153,000 million transistors on a 1017 mm² die, yielding a transistor density of 150.4M per mm². The RTX 4060 uses the AD107 chip on the Ada Lovelace architecture, also on a 5 nm TSMC process, with 18,900 million transistors on a 159 mm² die, giving a density of 118.9M per mm². The MI308X die is over six times larger and houses over eight times the transistor count.

The MI308X has 19,456 shading units and 1,216 texture mapping units, but zero ROPs. Its pixel rate is recorded as 0 MPixel/s, and its texture rate is 2,553.6 GTexel/s. The RTX 4060 has 3,072 shading units, 96 TMUs, and 48 ROPs, with a pixel rate of 118.1 GPixel/s and a texture rate of 236.2 GTexel/s. The MI308X does not list RT cores or tensor cores, while the RTX 4060 includes 24 RT cores and 96 tensor cores.

Memory architecture differs fundamentally. The MI308X uses 192 GB of HBM3 on an 8192-bit bus, delivering 5.32 TB/s of bandwidth. The RTX 4060 uses 8 GB of GDDR6 on a 128-bit bus, delivering 272.0 GB/s. The MI308X memory clock is 1300 MHz with 5.2 Gbps effective, while the RTX 4060 memory clock is 2125 MHz with 17 Gbps effective. The MI308X bus width is 64 times wider, and its bandwidth is roughly 19.6 times higher.

Clock speeds also differ. The MI308X has a base clock of 1000 MHz and a boost clock of 2100 MHz. The RTX 4060 has a base clock of 1830 MHz and a boost of 2460 MHz. The RTX 4060 runs at higher frequencies, but the MI308X compensates with far more compute units.

The MI308X uses an OAM Module slot width with no power connectors, and the system requires a suggested 1150 W PSU. The RTX 4060 is a dual-slot card, 240 mm long, 111 mm high, and 40 mm wide, with a single 12-pin power connector and a 300 W suggested PSU. The MI308X has no display outputs, while the RTX 4060 has 1x HDMI 2.1 and 3x DisplayPort 1.4a.

API support highlights the divide. The MI308X lists DirectX, OpenGL, and Vulkan as N/A. The RTX 4060 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The MI308X interfaces via PCIe 5.0 x16, while the RTX 4060 uses PCIe 4.0 x8.

The MI308X texture rate is 2,553.6 GTexel/s versus 236.2 GTexel/s for the RTX 4060.

The RTX 4060 wins on graphics features. It has 24 RT cores and 96 tensor cores, supports DirectX 12 Ultimate, and provides display outputs. The MI308X has no RT cores, no tensor cores, no graphics API support, and no display outputs. For any workload requiring real-time rendering, ray tracing, or standard graphics pipelines, the RTX 4060 is the only card with data supporting such use.

The RTX 4060 also wins on power efficiency. Its TDP is 115 W, and it requires a 300 W suggested PSU. The MI308X has a 750 W TDP and requires a 1150 W suggested PSU. The RTX 4060 achieves its recorded benchmark scores at a fraction of the power draw.

The MI308X wins on memory capacity and bandwidth, which matters for large data sets. The RTX 4060 wins on software ecosystem compatibility, given its API support and benchmark presence. The MI308X has no recorded average benchmark score, while the RTX 4060 has an average benchmark score of 17,639.
