AMD Instinct MI355X vs AMD Radeon 8060S Comparison

Where Each One Wins

The AMD Instinct MI355X and AMD Radeon 8060S occupy entirely different corners of the hardware landscape, and the benchmark data reflects that split. The MI355X is a compute-oriented accelerator with no display outputs, no DirectX or Vulkan support, and a 1400 W TDP. It is built for data center workloads, not for rendering frames. Its 78.64 TFLOPS of FP32 and FP16 compute, paired with 288 GB of HBM3e memory and 8.19 TB/s of bandwidth, positions it as a server-side workhorse. The Radeon 8060S, by contrast, is an integrated graphics processor (IGP) with a 55 W TDP, DirectX 12 Ultimate support, and 40 ray tracing cores. It targets portable devices and delivers 14.85 TFLOPS of FP32 and FP16 compute, along with 185.6 GPixel/s of pixel throughput.

The recorded data shows that the Radeon 8060S wins in any scenario where graphics APIs, display output, or power efficiency matter. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the MI355X lists N/A for all three. The 8060S also has 64 ROPs versus 0 for the MI355X, and a pixel rate of 185.6 GPixel/s versus 0 MPixel/s. For gaming, ray tracing, or any client-side rendering workload, the 8060S is the only viable option. The MI355X wins in raw compute throughput, memory capacity, and memory bandwidth, but it cannot output a single frame.

The percentile data also separates them. The MI355X sits at the 50th percentile among all GPUs in the database, with an average benchmark score of 0, since no benchmark results are recorded for it. The Radeon 8060S sits at the 87th percentile, with an average score of 55757 across three recorded tests: 3DMark Steel Nomad DX12 (2162), Geekbench OpenCL (84626), and Geekbench Vulkan (80483). The 8060S outperforms its nearest rivals by slim margins: it is 0.1% ahead of the AMD Radeon RX 6750 GRE 12 GB, 1.7% ahead of the AMD Radeon Pro W5700X, and 2.8% ahead of the NVIDIA GeForce RTX 4080, while sitting 0.6% behind the NVIDIA GeForce RTX 5080.

FAQ

Q: Does the AMD Instinct MI355X support DirectX or Vulkan?

A: No. The database lists DirectX, OpenGL, and Vulkan support as N/A for the MI355X. It has no display outputs, making it unsuitable for client-side graphics workloads.

Q: How much memory does each product have?

A: The MI355X has 288 GB of HBM3e memory on a 8192-bit bus with 8.19 TB/s of bandwidth. The Radeon 8060S uses System Shared memory, with type, bus width, and bandwidth all listed as System Dependent.

Q: What is the performance difference in raw FP32 compute?

A: The MI355X delivers 78.64 TFLOPS of FP32, which is roughly 5.3 times the 14.85 TFLOPS of the Radeon 8060S. Both products list FP16 at a 1:1 ratio with FP32.

Q: Which product has a higher benchmark percentile?

A: The Radeon 8060S ranks at the 87th percentile among all GPUs in the database, with an average score of 55757. The MI355X ranks at the 50th percentile with an average score of 0, as no benchmark entries exist for it.

Q: What is the TDP difference between the two?

A: The MI355X has a TDP of 1400 W with a suggested PSU of 1800 W, while the Radeon 8060S has a TDP of 55 W and no suggested PSU listed. The 8060S is an IGP, meaning it is integrated into a portable device.

Q: Does the Radeon 8060S support ray tracing?

A: Yes. The 8060S has 40 ray tracing cores and supports DirectX 12 Ultimate (12_2). The MI355X lists no ray tracing cores and no DirectX support.

Head-to-Head Benchmarks

The head-to-head benchmark table is empty in the database, with zero wins recorded for either product. This is expected, as the MI355X has no benchmark scores on file. The only measurable comparisons come from the Radeon 8060S's own benchmark results and its nearest rivals.

The 8060S scores 2162 in 3DMark Steel Nomad DX12, 84626 in Geekbench OpenCL, and 80483 in Geekbench Vulkan. These results place it 0.1% ahead of the AMD Radeon RX 6750 GRE 12 GB (average score 55698), 1.7% ahead of the AMD Radeon Pro W5700X (54828), and 2.8% ahead of the NVIDIA GeForce RTX 4080 (54247). It trails the NVIDIA GeForce RTX 5080 (56083) by 0.6%. These deltas are narrow, indicating that the 8060S performs in the same band as those discrete desktop cards despite being an integrated solution.

For the MI355X, the absence of benchmark data means no direct performance comparisons can be drawn. The database lists its raw specifications, but without recorded scores, any head-to-head analysis must rely on theoretical throughput. The MI355X's 78.64 TFLOPS of FP32 is over five times the 8060S's 14.85 TFLOPS, and its 8.19 TB/s of memory bandwidth dwarfs the 8060S's System Dependent bandwidth. But these figures do not translate into frame rates or API-level performance, since the MI355X cannot render graphics.

The biggest wins in this comparison are structural. The 8060S wins on software compatibility, display support, and efficiency, while the MI355X wins on compute density, memory capacity, and bandwidth. Each product leads in the categories that define its intended use case.

Architecture Differences

The two products use fundamentally different GPU architectures from AMD, reflecting their distinct design goals.

The MI355X is built on the CDNA 4.0 architecture, which is optimized for compute and data center acceleration. Its chip is designated MI350 256CU, indicating 256 compute units. The architecture is designed for high-throughput FP32 and FP16 calculations, with a 1:1 ratio between the two precisions. The MI355X uses a 3 nm process, which allows for a massive die of 2380 mm² housing 185,000 million transistors. The memory subsystem is purpose-built for bandwidth: 288 GB of HBM3e on an 8192-bit bus delivers 8.19 TB/s. The absence of ROPs, ray tracing cores, and display outputs confirms that this architecture does not prioritize graphics rasterization. It is a pure compute accelerator.

The Radeon 8060S uses the RDNA 3.5 architecture, which is AMD's graphics-oriented design. Its chip is Strix Halo, and it belongs to the Navi Mobile (RX 8000M) generation. The architecture includes 2560 shading units, 160 TMUs, 64 ROPs, and 40 ray tracing cores, making it a full-featured graphics solution. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, and it can drive portable device displays. The 4 nm process and 308 mm² die size are much smaller than the MI355X, reflecting its integrated nature. The 8060S also uses System Shared memory, meaning it borrows from the host system's RAM rather than having dedicated VRAM. This architecture prioritizes power efficiency, with a 55 W TDP, and integration into mobile devices.

The architectural split is clear: CDNA 4.0 on the MI355X is built for raw compute throughput and massive memory bandwidth, while RDNA 3.5 on the 8060S is built for graphics rendering, API compatibility, and low power consumption. The MI355X's 16384 shading units and 1024 TMUs far exceed the 8060S's 2560 shading units and 160 TMUs, but the 8060S has the ROPs and ray tracing hardware that the MI355X lacks. The MI355X also has no API support in the database, while the 8060S supports the full modern graphics stack. These are not competing products; they are complementary designs for different workloads.
