AMD Radeon 8060S vs NVIDIA B300 SXM6 AC Comparison

Where Each One Wins

The benchmark data splits these two GPUs into entirely different performance classes. The NVIDIA B300 SXM6 AC wins the only head-to-head test recorded, the Geekbench OpenCL benchmark, with a score of 369,831 against the AMD Radeon 8060S’s 84,626. That is a 77.1% deficit for the AMD part in that single comparison.

The AMD Radeon 8060S does not win any direct head-to-head benchmark in the database. However, it has three recorded benchmarks of its own, including 3DMark Steel Nomad DX12 at 2,162 and Geekbench Vulkan at 80,483, which the NVIDIA B300 SXM6 AC does not have any recorded scores for. The AMD part’s average benchmark score is 55,757, placing it in the 87th percentile of all GPUs. The NVIDIA part’s average is 369,831, placing it in the 100th percentile.

The use-case split is therefore not about which wins individual tests, but about which workloads each can address at all. The AMD Radeon 8060S is an integrated graphics processor with DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support. The NVIDIA B300 SXM6 AC has no display outputs and lists its APIs as N/A, indicating it is not designed for client-side rendering workloads that rely on those graphics APIs. The AMD part is the only one of the two that can output to a display, with its outputs described as portable device dependent.

Architecture Differences

The two chips come from different manufacturers, nodes, and design philosophies. AMD uses the Strix Halo chip with RDNA 3.5 architecture, built on a 4 nm TSMC process. The die size is 308 mm², and transistor count is listed as unknown. NVIDIA uses the GB110 chip with Blackwell Ultra architecture, built on a 5 nm TSMC process. The die is 1,628 mm² and contains 208,000 million transistors, giving a transistor density of 127.8M per mm².

The AMD part has 2,560 shading units, 160 texture mapping units, and 64 ROPs. It includes 40 ray tracing cores and has no tensor cores listed. The NVIDIA part has 18,944 shading units, 592 texture mapping units, and only 24 ROPs. It has no ray tracing cores listed but includes 592 tensor cores. The ROP count difference is notable: NVIDIA’s design uses far fewer ROPs despite having far more shaders and TMUs.

Clock behavior differs substantially. The AMD chip runs at a 1,295 MHz base and boosts to 2,900 MHz. The NVIDIA chip runs at a 1,665 MHz base and boosts to 2,032 MHz. Despite the higher boost clock on the AMD side, the NVIDIA part’s massive shader count delivers far higher raw throughput. Pixel rate is 185.6 GPixel/s for AMD versus 48.77 GPixel/s for NVIDIA, a consequence of the ROP disparity. Texture rate is 464.0 GTexel/s for AMD versus 1,202.9 GTexel/s for NVIDIA.

Memory architecture is fundamentally different. AMD uses system shared memory with a system dependent bandwidth and no dedicated VRAM. NVIDIA uses 288 GB of HBM3e memory on an 8,192-bit bus, delivering 8.19 TB/s of bandwidth. The NVIDIA memory clock is listed as 2,000 MHz with 8 Gbps effective. The AMD memory clock is also listed as system shared.

Both parts are actively in production. The AMD part released on 2025-01-05 and has a predecessor of Polaris Mobile. The NVIDIA part released on 2025-09-10, has a predecessor of Server Hopper, and a successor of Server Rubin. The AMD generation is Navi Mobile (RX 8000M), while the NVIDIA generation is Server Blackwell (Bxx).

Head-to-Head Benchmarks

The only shared benchmark in the database is Geekbench OpenCL. The NVIDIA B300 SXM6 AC scores 369,831, and the AMD Radeon 8060S scores 84,626. The delta is 77.1% in favor of NVIDIA. This is a decisive margin, but it must be read in context of the different product categories. The NVIDIA part is a server module with 1,100 W TDP and a suggested 1,500 W power supply. The AMD part is an integrated GPU with a 55 W TDP and no power connectors.

NVIDIA’s nearest rivals in the database are all server-class parts. The B300 SXM6 AC leads the NVIDIA B200 by 7%, the NVIDIA H200 NVL by 10.4%, the AMD Instinct MI300X by 16.3%, and the NVIDIA L40S by 25%. These deltas show it sits at the top of the server GPU hierarchy. The AMD Radeon 8060S, by contrast, sits within 2.8% of the NVIDIA GeForce RTX 4080, within 1.7% of the AMD Radeon Pro W5700X, within 0.6% of the NVIDIA GeForce RTX 5080 (actually slightly behind), and within 0.1% of the AMD Radeon RX 6750 GRE 12 GB. Its average score of 55,757 is nearly identical to the RX 6750 GRE’s 55,698.

The AMD part’s other benchmarks, 3DMark Steel Nomad DX12 at 2,162 and Geekbench Vulkan at 80,483, have no NVIDIA counterpart scores in the database. The NVIDIA part has no scores for DirectX or Vulkan workloads, consistent with its lack of graphics API support. This means the head-to-head data is limited to compute-style OpenCL performance, where NVIDIA dominates.

The Verdict

The data indicates these are not competing products. The NVIDIA B300 SXM6 AC is a server module built for compute workloads, with 18,944 shading units, 592 tensor cores, 288 GB of HBM3e memory, and an 8.19 TB/s memory bandwidth. It has no display outputs and no graphics API support. Its 1,100 W TDP and 1,500 W suggested power supply confirm it is designed for data center installation. Its average benchmark score of 369,831 places it at the absolute top of the database.

The AMD Radeon 8060S is an integrated graphics processor with a 55 W TDP, no power connectors, and portable device dependent display outputs. It supports modern graphics APIs, includes 2,560 shading units and 40 ray tracing cores, and relies on system shared memory. Its average benchmark score of 55,757 places it in the 87th percentile, competitive with desktop GPUs like the NVIDIA GeForce RTX 4080 and RTX 5080.

For compute-heavy server workloads, the NVIDIA part is the clear choice based on the 77.1% lead in Geekbench OpenCL and its 100th percentile standing. For portable or client devices requiring graphics output and modern API support, the AMD part is the only option of the two, given the NVIDIA part’s lack of display outputs and N/A graphics APIs. The ROP count difference, 64 for AMD versus 24 for NVIDIA, further emphasizes that NVIDIA’s design prioritizes compute throughput over pixel pushing, while AMD’s design handles traditional graphics rendering tasks.
