AMD Instinct MI355X vs NVIDIA GeForce RTX 4060 Comparison

Where Each One Wins

The AMD Instinct MI355X and NVIDIA GeForce RTX 4060 occupy entirely different segments of the GPU market, and the benchmark data reflects this split. The MI355X is a compute-oriented accelerator with no display outputs, no graphics API support, and a 1400 W power envelope. The RTX 4060 is a consumer graphics card with full DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support, plus multiple display outputs. Their respective strengths align with these roles.

The RTX 4060 holds the only recorded benchmark results in the database. It has scores across ten tests spanning 3DMark Steel Nomad DX12, Geekbench OpenCL and Vulkan, PassMark DirectX 9/10/11/12, PassMark G2D, PassMark G3D, and PassMark GPU Compute. Its 3DMark Steel Nomad DX12 score of 2302 and PassMark G3D score of 19545 represent its strongest synthetic gaming and graphics workloads. The MI355X has no benchmark entries in the database, so its wins must be assessed from architectural specifications rather than measured test results.

The MI355X wins decisively on raw compute capacity. Its FP32 throughput of 78.64 TFLOPS is more than five times the RTX 4060's 15.11 TFLOPS. Its FP16 throughput matches at 78.64 TFLOPS, while the RTX 4060 delivers 15.11 TFLOPS in FP16. Texture rate tells a similar story: 2457.6 GTexel/s versus 236.2 GTexel/s. Memory bandwidth is the most extreme gap, with 8.19 TB/s against 272.0 GB/s, a difference of roughly 30 times.

The RTX 4060 wins on graphics-specific features. It has 48 ROPs and a pixel rate of 118.1 GPixel/s; the MI355X lists 0 ROPs and 0 MPixel/s. The RTX 4060 includes 24 RT cores and 96 tensor cores, while the MI355X lists none. The RTX 4060 supports display outputs, the MI355X has none. For any workload requiring rasterization, ray tracing, or display output, the RTX 4060 is the only functional choice between the two.

The MI355X instead targets memory-bound compute. Its 288 GB of HBM3e memory dwarfs the 8 GB GDDR6 on the RTX 4060. The 8192-bit memory bus compares to 128 bits. These specifications point toward large model inference and training workloads, not interactive graphics.

Architecture Differences

The two GPUs share a foundry, TSMC, but little else. The MI355X uses a 3 nm process, while the RTX 4060 uses 5 nm. The MI355X packs 185,000 million transistors onto a 2380 mm² die, giving a transistor density of 77.7 million per mm². The RTX 4060 uses 18,900 million transistors on a 159 mm² die, with a higher density of 118.9 million per mm². The MI355X's lower density reflects its massive HBM3e memory interface and compute-oriented layout.

The MI355X is built on CDNA 4.0 architecture and uses the MI350 256CU chip. It belongs to the Instinct (MIx) generation and succeeds Radeon Instinct. The RTX 4060 uses Ada Lovelace architecture with the AD107 chip, sits in the GeForce 40-series, and follows the GeForce 30 generation. The RTX 4060 is marked end-of-life, with the GeForce 50 as its successor.

Shading unit counts differ enormously. The MI355X has 16384 shading units and 1024 TMUs. The RTX 4060 has 3072 shading units and 96 TMUs. The MI355X's compute resources are organized for parallel throughput, while the RTX 4060 balances compute with fixed-function graphics hardware.

Clock behavior differs by design. The MI355X runs a 1000 MHz base clock and 2400 MHz boost. The RTX 4060 starts higher at 1830 MHz base and boosts to 2460 MHz. Memory clocks also differ: the MI355X uses 2000 MHz with 8 Gbps effective, while the RTX 4060 uses 2125 MHz with 17 Gbps effective. The MI355X compensates for lower memory clock speed with an 8192-bit bus versus 128 bits.

Physical specifications reflect their different roles. The MI355X is an OAM module measuring 102 mm by 165 mm, with no power connectors and a suggested PSU of 1800 W. The RTX 4060 is a dual-slot card at 240 mm by 111 mm by 40 mm, uses one 12-pin connector, and needs a 300 W suggested PSU. The MI355X consumes 1400 W, the RTX 4060 consumes 115 W.

The MI355X has no graphics API support in the database: DirectX, OpenGL, and Vulkan are all listed as N/A. The RTX 4060 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The MI355X also has no display outputs, while the RTX 4060 provides 1x HDMI 2.1 and 3x DisplayPort 1.4a. The MI355X uses PCIe 5.0 x16; the RTX 4060 uses PCIe 4.0 x8.

The Verdict

The recorded data shows two products with no direct head-to-head benchmarks and no overlapping use cases. The MI355X has no benchmark scores, a 50th percentile ranking versus all GPUs, and an average benchmark score of zero. The RTX 4060 has ten benchmark scores, a 61st percentile ranking, and a 17639 average benchmark score.

For compute workloads that fit within a single accelerator's memory and use FP16 or FP32 math, the MI355X's specifications indicate dominance. Its 78.64 TFLOPS in both FP32 and FP16, 288 GB of HBM3e, and 8.19 TB/s bandwidth provide roughly five times the FP32 throughput and thirty times the bandwidth of the RTX 4060. The lack of display outputs and graphics APIs does not matter for server-side compute.

For graphics, gaming, or any workload requiring a display, the RTX 4060 is the only viable option. Its DirectX 12 Ultimate support, 118.1 GPixel/s pixel rate, 24 RT cores, and 96 tensor cores enable modern rendering features that the MI355X cannot provide. Its 8 GB memory is sufficient for mainstream gaming and desktop applications.

The RTX 4060's nearest rivals in the database are all AMD Radeon products with similar average scores. The AMD Radeon HD 7790 scores 17666, a 0.2% delta. The AMD Radeon 780M scores 17588, a 0.3% delta. The AMD Radeon Pro 560 scores 17551, a 0.5% delta. The AMD Radeon Pro 460 scores 17509, a 0.7% delta. The RTX 4060's average of 17639 sits in the middle of this cluster, indicating its performance class is well established among consumer and workstation GPUs.

The MI355X has no nearest rivals listed, which reflects its unique position as a high-memory compute accelerator with no direct competitors in the current database. Its 50th percentile ranking suggests it is not compared against typical consumer GPUs.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between the MI355X and RTX 4060. The MI355X has no benchmark scores recorded, while the RTX 4060 has ten. The comparison below relies on the RTX 4060's recorded results and the MI355X's architectural specifications.

The RTX 4060's strongest recorded result is its PassMark G3D score of 19545. Its PassMark G2D score of 1037 reflects 2D graphics capability. In compute tests, it scores 95057 in Geekbench OpenCL and 48643 in Geekbench Vulkan. Its PassMark GPU Compute score is 9213. In 3DMark Steel Nomad DX12, it scores 2302.

The RTX 4060's PassMark legacy DirectX results show a clear pattern. DirectX 9 scores 236, DirectX 10 scores 103, DirectX 11 scores 175, and DirectX 12 scores 76. These results indicate the card's relative performance across different API generations, with the highest score appearing in the older DirectX 9 workload.

The MI355X's FP32 throughput of 78.64 TFLOPS compares to the RTX 4060's 15.11 TFLOPS. The MI355X's FP16 throughput of 78.64 TFLOPS matches its FP32 figure, indicating a 1:1 ratio. The RTX 4060 also runs FP16 at 1:1 with FP32, at 15.11 TFLOPS. Both cards therefore process FP16 at the same rate as FP32, but the MI355X operates at over five times the absolute throughput.

Memory bandwidth is where the MI355X separates itself most clearly. Its 8.19 TB/s bandwidth is approximately 30 times the RTX 4060's 272.0 GB/s. Combined with 288 GB of capacity, this allows the MI355X to handle data sets that would require multiple RTX 4060-class cards or significant system memory offloading.

Texture rate favors the MI355X at 2457.6 GTexel/s versus 236.2 GTexel/s, a factor of roughly 10.4. Pixel rate favors the RTX 4060 at 118.1 GPixel/s, since the MI355X has no ROPs and records 0 MPixel/s. The MI355X's transistor count of 185,000 million versus 18,900 million reflects its much larger die and compute-focused design.

The RTX 4060's boost clock of 2460 MHz slightly exceeds the MI355X's 2400 MHz boost. The RTX 4060 also has a higher base clock at 1830 MHz versus 1000 MHz. The MI355X compensates with 8192 shading units more than the RTX 4060's 3072, and 928 additional TMUs.

The database's percentile rankings place the RTX 4060 at 61 percent versus all GPUs, with an average score of 17639. The MI355X sits at 50 percent with a zero average score, reflecting its absence of recorded benchmarks. The RTX 4060's nearest rivals, all within 0.7% of its average score, confirm its established position among consumer and workstation GPUs. The MI355X has no comparable rivals listed, reinforcing its status as a specialized compute accelerator without direct consumer-market competition in the database.
