AMD Instinct MI355X vs NVIDIA GeForce RTX 4060 AD106 Comparison

Head-to-Head Benchmarks

The database records no benchmark entries for either the AMD Instinct MI355X or the NVIDIA GeForce RTX 4060 AD106. The head-to-head benchmark table is empty, and neither processor holds a single win in recorded testing. Both units sit at the same percentile rank of 50 against all GPUs, with an average benchmark score of 0. This makes a direct performance comparison impossible using the recorded data. The absence of scores means no conclusions can be drawn about relative speed, frame rates, or compute throughput from our measurements.

The MI355X posts theoretical peak figures that dwarf the RTX 4060. Its FP32 output is listed at 78.64 TFLOPS, while the RTX 4060 reaches 15.11 TFLOPS. That is a gap of roughly 63.53 TFLOPS in favor of the Instinct part. FP16 performance follows the same pattern: the MI355X again shows 78.64 TFLOPS, matching its FP32 rate at a 1:1 ratio, whereas the RTX 4060 also lists 15.11 TFLOPS for FP16. Texture rate differs substantially: the MI355X offers 2,457.6 GTexel/s against 236.2 GTexel/s for the RTX 4060. Pixel rate goes the other way: the RTX 4060 outputs 118.1 GPixel/s, while the MI355X is recorded at 0 MPixel/s, as it has no ROPs.

Memory bandwidth heavily favors the AMD part. The MI355X has 8.19 TB/s of bandwidth over an 8192-bit bus, compared to 272.0 GB/s on a 128-bit bus for the NVIDIA card. That is a 30-fold difference in memory throughput. However, these are architectural specifications, not measured benchmark results. Without actual benchmark scores in the database, the recorded wins column remains at zero for both units, and no percentile movement occurs beyond the shared 50th rank.

Architecture Differences

The two processors come from entirely different design philosophies. The AMD Instinct MI355X uses the CDNA 4.0 architecture, built on a 3 nm process at TSMC. Its chip is labeled MI350 256CU, and it belongs to the Instinct (MIx) generation. The NVIDIA GeForce RTX 4060 AD106 employs the Ada Lovelace architecture on a 5 nm process, also from TSMC. It is part of the GeForce 40 series.

Transistor counts show a vast difference. The MI355X packs 185,000 million transistors on a die size of 2380 mm², giving a transistor density of 77.7M per mm². The RTX 4060 uses 22,900 million transistors on a 188 mm² die, with a density of 121.8M per mm². The smaller NVIDIA die achieves a higher density, but the AMD chip has over eight times the total transistor count.

Shading units favor AMD heavily: 16,384 for the MI355X versus 3,072 for the RTX 4060. Texture mapping units also differ: 1,024 versus 96. The RTX 4060 has 48 ROPs, while the MI355X has 0. The NVIDIA part includes 24 RT cores and 96 tensor cores. The AMD part lists no RT cores and no tensor cores in the database. This reflects a compute-optimized design versus a graphics-oriented one.

Memory types diverge completely. The MI355X uses 288 GB of HBM3e with an 8192-bit bus width. The RTX 4060 has 8 GB of GDDR6 on a 128-bit bus. Clock speeds show the NVIDIA chip running higher: 1830 MHz base and 2460 MHz boost, versus 1000 MHz base and 2400 MHz boost for AMD. Memory clock also favors NVIDIA at 2125 MHz (17 Gbps effective), while the MI355X runs at 2000 MHz (8 Gbps effective). The RTX 4060 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The MI355X lists N/A for all three APIs.

Power and physical design differ starkly. The MI355X has a TDP of 1400 W, uses an OAM Module slot width, has no power connectors, and requires an 1800 W suggested PSU. It has no display outputs. The RTX 4060 draws 115 W, fits a dual-slot design, uses a single 12-pin connector, and needs a 300 W suggested PSU. It provides 1x HDMI 2.1 and 3x DisplayPort 1.4a outputs. The MI355X measures 102 mm by 165 mm. The RTX 4060 has no recorded dimensions.

Where Each One Wins

The AMD Instinct MI355X wins on raw compute throughput. Its FP32 and FP16 figures of 78.64 TFLOPS are five times higher than the RTX 4060's 15.11 TFLOPS. Texture rate of 2,457.6 GTexel/s exceeds the NVIDIA part by an order of magnitude. Memory bandwidth of 8.19 TB/s versus 272.0 GB/s gives the MI355X a massive advantage for data-heavy workloads. Its 288 GB capacity dwarfs the 8 GB on the RTX 4060. The 8192-bit bus width allows feeding that capacity at speeds no consumer card can match. The MI355X targets compute tasks where memory size and bandwidth are the limiting factors.

The NVIDIA GeForce RTX 4060 wins on graphics features and efficiency. It has 48 ROPs and a pixel rate of 118.1 GPixel/s, where the MI355X has none. The RTX 4060 includes 24 RT cores and 96 tensor cores for ray tracing and AI acceleration, neither of which the AMD part lists. It supports modern graphics APIs: DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. The MI355X lists N/A for all APIs, meaning it is not built for interactive graphics. The RTX 4060 draws 115 W versus 1400 W, a 12-fold difference in power consumption. Its 5 nm process and higher clock speeds (1830 MHz base, 2460 MHz boost) contribute to that efficiency. The RTX 4060 has display outputs, making it usable for gaming or workstation graphics output, while the MI355X has none.

The RTX 4060 has a higher transistor density at 121.8M per mm² versus 77.7M per mm², indicating a more compact design. It also supports a faster boost clock: 2460 MHz against 2400 MHz. The NVIDIA part uses PCIe 4.0 x8, while the AMD part uses PCIe 5.0 x16, giving the MI355X a newer and wider bus interface. Production status differs: the RTX 4060 is end-of-life, while the MI355X has no recorded status. Release dates show the RTX 4060 launched earlier, on 2024-03-31, with the MI355X following on 2025-06-11.

The Verdict

The data points to two different tools for two different jobs. The AMD Instinct MI355X is a compute accelerator. Its 78.64 TFLOPS FP32, 288 GB of HBM3e, and 8.19 TB/s bandwidth make it suitable for large-scale data processing, scientific simulation, or AI training workloads where memory capacity and throughput are critical. The absence of display outputs, graphics APIs, and ROPs confirms it is not a gaming card. The 1400 W TDP and 1800 W suggested PSU indicate a data center installation, not a desktop PC.

The NVIDIA GeForce RTX 4060 AD106 is a consumer graphics card. Its 118.1 GPixel/s pixel rate, 24 RT cores, and 96 tensor cores target gaming, ray tracing, and DLSS-style workloads. The 115 W TDP and 300 W suggested PSU make it suitable for standard desktop builds. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, and it provides display outputs for monitors. The 8 GB of GDDR6 memory is a limiting factor for large datasets, but it is sufficient for typical gaming resolutions.

The MI355X has several times the shading units (16,384 versus 3,072), TMUs (1,024 versus 96), and memory bandwidth (8.19 TB/s versus 272.0 GB/s). The RTX 4060 counters with higher clock speeds (2460 MHz versus 2400 MHz boost), a higher transistor density (121.8M versus 77.7M per mm²), and a much lower power draw. The RTX 4060 is end-of-life per the database, while the MI355X has no recorded production status. The MI355X uses PCIe 5.0 x16, while the RTX 4060 uses PCIe 4.0 x8.

The choice depends on the workload. For compute-heavy tasks with large memory footprints, the MI355X is the only option with adequate specifications. For graphics rendering, gaming, or any display output, the RTX 4060 is the functional choice. The two share the same percentile rank of 50 in the database, but that figure reflects no benchmark data rather than equal performance. The recorded specifications show a clear split: the MI355X for acceleration, the RTX 4060 for graphics.
