AMD Instinct MI355X vs NVIDIA GeForce RTX 4060 Max-Q Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark entries for the AMD Instinct MI355X and the NVIDIA GeForce RTX 4060 Max-Q. Both products have an empty benchmark array, an average benchmark score of zero, and a percentile rank of 50 against all GPUs in the database. With zero wins recorded for either side in the head-to-head field, the comparative performance picture must be derived entirely from their architectural and specification sheets rather than from measured workload results.

What the available data does show is a stark split in raw compute capability. The AMD Instinct MI355X delivers 78.64 TFLOPS of FP32 throughput, while the NVIDIA GeForce RTX 4060 Max-Q delivers 9.032 TFLOPS. That places the Instinct part at roughly 8.7 times the FP32 rate of the mobile NVIDIA chip, a gap that reflects their entirely different design targets. The texture rate differential is similarly pronounced: the MI355X reaches 2,457.6 GTexel/s against 141.1 GTexel/s for the RTX 4060 Max-Q, a factor of about 17.4. The pixel rate comparison inverts, however, because the MI355X reports 0 MPixel/s while the RTX 4060 Max-Q produces 70.56 GPixel/s, indicating that the AMD accelerator has no conventional raster output stage.

Memory bandwidth follows the compute divide. The MI355X accesses 288 GB of HBM3e across an 8192 bit bus for 8.19 TB/s of bandwidth, whereas the RTX 4060 Max-Q uses 8 GB of GDDR6 on a 128 bit bus for 256.0 GB/s. The bandwidth ratio is approximately 32 to 1 in favor of the AMD part. These are not comparable product classes in any measured sense, and the absence of benchmark scores in the database confirms that no common workload has been recorded for both.

Architecture Differences

The AMD Instinct MI355X is built on the CDNA 4.0 architecture and uses the MI350 256CU chip, fabricated by TSMC on a 3 nm process. The NVIDIA GeForce RTX 4060 Max-Q uses the Ada Lovelace architecture with the AD107 chip, also from TSMC but on a 5 nm node. The process difference is meaningful: 3 nm versus 5 nm, though the transistor counts point in the opposite direction of what the node alone would suggest. The MI355X integrates 185,000 million transistors on a 2380 mm² die, yielding a transistor density of 77.7M per mm². The RTX 4060 Max-Q contains 18,900 million transistors on a 159 mm² die, for a density of 118.9M per mm². The NVIDIA chip is therefore denser per square millimeter, while the AMD chip is dramatically larger in absolute terms.

The MI355X is an accelerator, not a graphics card. It has no display outputs, no DirectX, OpenGL, or Vulkan API support, and no ROPs, with a pixel rate reported as 0 MPixel/s. The RTX 4060 Max-Q is a full graphics processor with 48 ROPs, 24 ray tracing cores, 96 tensor cores, DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4 support. The MI355X has no listed ray tracing or tensor core counts, which aligns with its compute-focused CDNA 4.0 design rather than a rendering-oriented one.

The memory subsystems differ in type, capacity, and interface. The MI355X uses HBM3e memory totaling 288 GB on an 8192 bit bus. The RTX 4060 Max-Q uses 8 GB of GDDR6 on a 128 bit bus. Effective memory clock values are both recorded as 2000 MHz, with the MI355X achieving 8 Gbps effective and the RTX 4060 Max-Q achieving 16 Gbps effective. The higher per-pin data rate on the NVIDIA part does not compensate for the vastly wider AMD interface.

Power and physical design separate the two even further. The MI355X carries a 1400 W TDP, requires an 1800 W suggested power supply, and mounts as an OAM Module with 102 mm length and 165 mm width. The RTX 4060 Max-Q is an IGP with a 35 W TDP, no suggested PSU, and no recorded dimensions, consistent with a mobile integrated GPU. Neither product uses external power connectors according to the data.

The bus interfaces also differ: the MI355X connects over PCIe 5.0 x16, while the RTX 4060 Max-Q uses PCIe 4.0 x8. Clock behavior shows the MI355X with a 1000 MHz base and 2400 MHz boost, while the RTX 4060 Max-Q runs a 1140 MHz base and 1470 MHz boost. The AMD part boosts higher, but its power envelope is 40 times larger.

The Verdict

The data indicates that these two products are not competitors. The AMD Instinct MI355X is a data center accelerator with 288 GB of HBM3e, 8.19 TB/s of bandwidth, 78.64 TFLOPS of FP32, and a 1400 W TDP, built for compute workloads that cannot fit in a small memory pool. The NVIDIA GeForce RTX 4060 Max-Q is a mobile graphics processor with 8 GB of GDDR6, 256.0 GB/s of bandwidth, 9.032 TFLOPS of FP32, and a 35 W TDP, designed for rendering and general GPU tasks inside a laptop. The MI355X has no display outputs and no graphics API support, so it cannot drive a screen. The RTX 4060 Max-Q has full DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support plus ray tracing and tensor cores, so it covers the entire client rendering feature set.

The recorded percentile ranks are identical at 50 for both, and both have an average benchmark score of zero, but that parity reflects missing data rather than equal performance. No measured workload in the database links the two. The MI355X is positioned for memory-bound and throughput-bound compute installations where 1400 W is acceptable. The RTX 4060 Max-Q is positioned for power-constrained mobile systems where 35 W is the ceiling. A buyer choosing between them would be deciding between an OAM module with no outputs and an IGP for a portable device, which is not a meaningful choice in practice.

Where Each One Wins

The AMD Instinct MI355X wins in raw compute throughput, memory capacity, memory bandwidth, and texture processing. Its 78.64 TFLOPS FP32 and 78.64 TFLOPS FP16 (1:1) make it suited to workloads that saturate floating-point units. Its 288 GB HBM3e pool and 8.19 TB/s bandwidth suit datasets that would overflow smaller memory subsystems. Its 2,457.6 GTexel/s texture rate supports heavy texture sampling workloads. The 8192 bit bus is the widest interface in this comparison, and the PCIe 5.0 x16 link provides a faster host connection than the RTX 4060 Max-Q's PCIe 4.0 x8.

The NVIDIA GeForce RTX 4060 Max-Q wins in every client-facing category. It has 48 ROPs and a 70.56 GPixel/s pixel rate, whereas the MI355X has none. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the MI355X lists N/A for all three. It includes 24 ray tracing cores and 96 tensor cores, which the MI355X does not list. It operates at 35 W TDP, making it viable for portable devices, while the MI355X requires a 1400 W budget and an 1800 W suggested power supply. It is also the only one of the two with a production status of Active, and it has a defined successor in the GeForce 50 Mobile series. The MI355X has a higher boost clock at 2400 MHz versus 1470 MHz, but that advantage is irrelevant for graphics workloads because the chip cannot render frames. The RTX 4060 Max-Q also uses a denser transistor layout at 118.9M per mm² versus 77.7M per mm², indicating a more compact design per unit of silicon area, though the MI355X compensates with a far larger die. For any task involving a display, graphics APIs, ray tracing, or mobile power constraints, the RTX 4060 Max-Q is the only option in this pair. For any task requiring extreme FP32 throughput or massive memory capacity, the MI355X is the only option.
