AMD Radeon 8050S vs NVIDIA B300 SXM6 AC Comparison

Head-to-Head Benchmarks

The database contains one direct benchmark comparison between the AMD Radeon 8050S and the NVIDIA B300 SXM6 AC: the Geekbench OpenCL test. In this measurement, the NVIDIA B300 SXM6 AC scores 369,831, while the AMD Radeon 8050S scores 65,818. The delta is 82.2% in favor of the NVIDIA part, meaning the B300 SXM6 AC delivers roughly 5.6 times the OpenCL score of the Radeon 8050S.

This is a decisive victory for the NVIDIA accelerator, and it aligns with the overall percentile rankings. The B300 SXM6 AC sits at the 100th percentile of all GPUs in the database, while the Radeon 8050S ranks at the 89th percentile. The gap between these two positions is substantial: the 8050S is competitive with mobile and workstation GPUs in the upper tier, but the B300 SXM6 AC occupies the absolute top of the performance distribution.

The average benchmark score for the NVIDIA part is 369,831, which is its only recorded benchmark result. The AMD part has a higher average of 62,108, computed from two results: 65,818 in OpenCL and 58,398 in Vulkan. However, even the Radeon's best score does not approach the NVIDIA's single result. When comparing the B300 SXM6 AC to its nearest rivals, the data shows a 7% lead over the NVIDIA B200, a 10.4% lead over the NVIDIA H200 NVL, a 16.3% lead over the AMD Instinct MI300X, and a 25% lead over the NVIDIA L40S.

The Radeon 8050S, by contrast, is closely matched with its nearest competitors. It sits 0.3% ahead of the AMD Radeon Pro W6600M, and 2.5% behind the AMD Radeon Pro Vega 56, 2.6% behind the AMD Radeon RX 7600M, and 2.7% behind the AMD Radeon RX 9060 XT LP. These small deltas indicate that the 8050S is firmly in a performance tier that is several orders of magnitude below the B300 SXM6 AC.

The head-to-head benchmark table records only one test, and the NVIDIA part wins that test. There are no recorded wins for the AMD part in direct comparison. This is consistent with the product positioning: the Radeon 8050S is an integrated GPU in a mobile APU, while the B300 SXM6 AC is a server-class accelerator module.

Where Each One Wins

The recorded data shows a single clear winner in the only shared benchmark. The NVIDIA B300 SXM6 AC dominates OpenCL compute, which is a common workload for AI training, scientific simulation, and high-performance computing. Its score of 369,831 is unmatched in the database, placing it above all other recorded GPUs. The nearest rival, the NVIDIA B200, scores 345,482, which is 7% lower. This indicates that the B300 SXM6 AC is not just marginally faster, but a step above the previous generation of server accelerators.

The AMD Radeon 8050S, while far behind in raw compute, has its own strengths in the mobile segment. It records a Vulkan score of 58,398, which is a measure of graphics API performance. The B300 SXM6 AC has no Vulkan result and, in fact, lists no supported APIs for DirectX, OpenGL, or Vulkan. This is expected for a server part with no display outputs. The Radeon 8050S supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, making it suitable for graphics workloads on portable devices.

The use-case split is therefore stark. The NVIDIA B300 SXM6 AC is a compute monster with 288 GB of HBM3e memory and 8.19 TB/s of bandwidth, designed for massive parallel workloads. The AMD Radeon 8050S uses system shared memory, with bandwidth described as system dependent, and delivers 11.47 TFLOPS of FP32 performance. The B300 SXM6 AC delivers 76.99 TFLOPS of FP32, which is 6.7 times higher.

In terms of memory capacity, the difference is even more pronounced. The B300 SXM6 AC has a dedicated 288 GB HBM3e pool, while the Radeon 8050S relies on shared system memory with no fixed size or bandwidth. This makes the NVIDIA part suitable for models and datasets that require hundreds of gigabytes, while the AMD part is constrained by what the host system provides.

The B300 SXM6 AC also leads in texture rate (1,202.9 GTexel/s vs. 358.4 GTexel/s) and shading units (18,944 vs. 2,048). However, the Radeon 8050S has a higher pixel rate (179.2 GPixel/s vs. 48.77 GPixel/s), which reflects its graphics-oriented design with 64 ROPs compared to 24 ROPs on the NVIDIA part. This is an interesting divergence: the AMD integrated GPU is better at pixel output, while the NVIDIA accelerator is overwhelmingly better at compute and texture work.

Architecture Differences

The two products come from different architectural lineages. The AMD Radeon 8050S is built on the RDNA 3.5 architecture, using the Strix Halo chip, and belongs to the Navi Mobile (RX 8000M) generation. The NVIDIA B300 SXM6 AC uses the Blackwell Ultra architecture, built on the GB110 chip, and belongs to the Server Blackwell (Bxx) generation.

The manufacturing processes differ, with the AMD part on a 4 nm TSMC node and the NVIDIA part on a 5 nm TSMC node. Despite the larger process node, the NVIDIA chip is vastly larger: 1,628 mm² die size compared to 308 mm² for the AMD chip. The transistor counts tell a similar story: the NVIDIA GB110 packs 208,000 million transistors, while the transistor count for the AMD Strix Halo is listed as unknown. The NVIDIA chip achieves a transistor density of 127.8 million per mm².

Clock speeds favor the AMD part in terms of boost clock. The Radeon 8050S has a base clock of 1295 MHz and a boost clock of 2800 MHz. The B300 SXM6 AC has a base clock of 1665 MHz and a boost clock of 2032 MHz. So while the NVIDIA part starts at a higher frequency, the AMD part boosts significantly higher. However, this clock advantage does not translate into performance leadership, as the NVIDIA part has 9.25 times more shading units.

The memory subsystems are fundamentally different. The Radeon 8050S uses system shared memory, with the memory type, bus width, and bandwidth all listed as system dependent. The B300 SXM6 AC uses 288 GB of HBM3e on an 8192-bit bus, delivering 8.19 TB/s of bandwidth. The memory clock for the NVIDIA part is 2000 MHz with 8 Gbps effective speed, while the AMD part lists no dedicated memory clock.

Compute resources differ substantially. The Radeon 8050S has 2,048 shading units, 128 texture mapping units, 64 ROPs, and 32 ray tracing cores. The B300 SXM6 AC has 18,944 shading units, 592 TMUs, 24 ROPs, and 592 tensor cores. The NVIDIA part has no listed ray tracing cores, while the AMD part has no listed tensor cores. This reflects their different design goals: the Radeon is a graphics-first integrated GPU, while the B300 is a compute-first accelerator with tensor cores for AI workloads.

The FP32 and FP16 performance are both listed at 11.47 TFLOPS for the AMD part, indicating a 1:1 ratio. The NVIDIA part also has a 1:1 ratio, but at 76.99 TFLOPS for both FP32 and FP16. The power envelopes are dramatically different: the Radeon 8050S has a TDP of 55 W and is an integrated GPU (IGP) with no power connectors, while the B300 SXM6 AC has a TDP of 1100 W, is an SXM module, and requires a suggested power supply of 1500 W.

The bus interfaces also differ: the AMD part uses PCIe 5.0 x16, while the NVIDIA part uses PCIe 6.0 x16. Display outputs are portable device dependent for the AMD part, while the NVIDIA part has no outputs.

The Verdict

The data indicates a clear performance hierarchy. The NVIDIA B300 SXM6 AC is the fastest GPU in the database, ranking at the 100th percentile with an OpenCL score of 369,831. The AMD Radeon 8050S ranks at the 89th percentile with an average score of 62,108, placing it in the upper-midrange of all GPUs but far from the top.

For workloads that depend on massive compute throughput, large memory capacity, and high bandwidth, the B300 SXM6 AC is the only choice. Its 288 GB HBM3e memory and 8.19 TB/s bandwidth enable workloads that would be impossible on a shared-memory integrated GPU. The 76.99 TFLOPS FP32 performance is 6.7 times higher than the Radeon's 11.47 TFLOPS.

For mobile or portable graphics workloads, the Radeon 8050S has the advantage of integration. It consumes 55 W, requires no power connectors, and supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. The B300 SXM6 AC consumes 1100 W, requires a 1500 W power supply, and has no graphics API support.

The record shows 0 wins for the AMD part and 1 win for the NVIDIA part in direct comparison. This is not a close contest. The B300 SXM6 AC is in a different performance class, as evidenced by its 82.2% lead in the only shared benchmark. The Radeon 8050S is competitive within its own tier, as shown by its narrow 0.3% lead over the Radeon Pro W6600M and its proximity to the RX 7600M and RX 9060 XT LP.

The architectural differences reinforce the benchmark results. The B300 SXM6 AC uses a 1,628 mm² die with 208,000 million transistors, while the Radeon 8050S uses a 308 mm² die with an unknown transistor count. The NVIDIA part has 9.25 times more shading units and 4.63 times more TMUs. The AMD part has 2.67 times more ROPs and a higher boost clock, but these advantages do not compensate for the massive compute disparity.

The release dates show the B300 SXM6 AC launched on September 10, 2025, while the Radeon 8050S launched on January 5, 2025. The NVIDIA part succeeds the Server Hopper generation and is succeeded by Server Rubin, while the AMD part succeeds Polaris Mobile with no listed successor. This positions the B300 SXM6 AC as a current-generation server flagship, while the Radeon 8050S is a mobile integrated GPU.
