AMD FirePro S7150 vs AMD Radeon RX 6800M Comparison

The AMD Radeon RX 6800M and the AMD FirePro S7150 represent two vastly different eras and purposes within AMD's hardware lineup. The RX 6800M is a modern, high-performance mobile gaming GPU built on the efficient RDNA 2.0 architecture, while the FirePro S7150 is a server-oriented compute card from the previous generation, designed for professional workloads. The benchmark data included here provides a clear, if limited, picture of their relative performance, with the RX 6800M holding a decisive lead in the tests where both are measured.

Where Each One Wins

The data is unambiguous in its verdict when looking at the shared benchmark results. The AMD Radeon RX 6800M wins both of the head-to-head tests that are available for comparison, leaving the AMD FirePro S7150 with zero wins in this dataset. This is not a close contest by any measure; the RX 6800M secures a 230.1% lead in Geekbench OpenCL and a 219.2% lead in Geekbench Vulkan.

The RX 6800M's strengths are rooted in its modern architecture and higher specification levels. Its wins are across the board in general-purpose compute (OpenCL) and modern graphics APIs (Vulkan), indicating it is the superior choice for any task that leverages these interfaces. The FirePro S7150, despite being a server-class product, cannot compete on raw throughput with the newer part.

The FirePro S7150's only potential "win" is in its design philosophy. It is a single-slot, 150 W card with no display outputs, purpose-built for rack-mounted servers where power density and physical footprint matter. Its 8 GB of VRAM on a 256-bit bus is a configuration aimed at large datasets, though the bandwidth is limited. However, in terms of pure benchmark performance, it does not win in any measured category.

Architecture Differences

The architectural gap between these two GPUs is vast, reflecting the five-year difference in their release timelines. The RX 6800M is built on the Navi 22 chip using the RDNA 2.0 architecture, fabricated on a 7 nm process at TSMC. This allows for a staggering 17,200 million transistors packed into a 335 mm² die, resulting in a transistor density of 51.3M / mm². In contrast, the FirePro S7150 uses the Tonga chip with the GCN 3.0 architecture, built on a much older 28 nm process. It contains only 5,000 million transistors on a larger 366 mm² die, yielding a density of just 13.7M / mm².

This fundamental difference in process technology and architecture leads to major feature disparities. The RX 6800M supports DirectX 12 Ultimate (12_2) and includes 40 ray tracing cores, a feature entirely absent from the FirePro S7150. The FirePro S7150 tops out at DirectX 12 (12_0) and has no RT cores listed. While both support OpenGL 4.6, the RX 6800M has a newer Vulkan version (1.4) compared to the FirePro's 1.2.170.

Memory technology also diverges. The RX 6800M uses 12 GB of GDDR6 memory on a 192-bit bus, delivering 384.0 GB/s of bandwidth. The FirePro S7150 uses 8 GB of GDDR5 on a wider 256-bit bus but achieves only 160.0 GB/s due to its much slower 1250 MHz memory clock. The RX 6800M's memory clock is listed as 2000 MHz with 16 Gbps effective speed. The RX 6800M also communicates over the faster PCIe 4.0 x16 interface, while the FirePro S7150 is limited to PCIe 3.0 x16.

Head-to-Head Benchmarks

The two available head-to-head benchmarks paint a dramatic picture of generational improvement. In Geekbench OpenCL, the AMD Radeon RX 6800M scores 87,621 against the AMD FirePro S7150's 26,543. This represents a massive 230.1% advantage for the RX 6800M. This test is a strong indicator of general-purpose compute performance, and the result shows that the newer RDNA 2.0 architecture is more than three times as efficient and powerful in this workload.

The results are similarly lopsided in Geekbench Vulkan, a test for modern graphics and compute workloads. Here, the RX 6800M achieves 94,766 points, while the FirePro S7150 manages only 29,690. This is a 219.2% difference in favor of the RX 6800M. This massive gap in Vulkan performance highlights the RX 6800M's support for the latest graphics APIs and its superior hardware capabilities, such as its 12.24 TFLOPS of FP32 power versus the FirePro's 3.768 TFLOPS.

The RX 6800M also has a suite of additional benchmarks not available for the FirePro S7150, including a 13,261 score in Passmark G3D and a 5,032 score in Passmark GPU Compute, further demonstrating its overall capability. The FirePro S7150's only other benchmark is a Geekbench OpenCL score, which is already accounted for. The data shows a clear and overwhelming performance victory for the RX 6800M in every measurable metric.

The Verdict

Based strictly on the data, the choice is clear for almost any use case. The AMD Radeon RX 6800M is the superior performer. It offers more than double the performance in both OpenCL and Vulkan compute workloads, supports modern features like ray tracing and DirectX 12 Ultimate, and has significantly higher memory bandwidth.

The AMD FirePro S7150 is a specialized server part. Its single-slot design, 150 W TDP, and lack of display outputs make it suitable for dense compute servers, but its performance is severely outdated. Its 28 nm process and GCN 3.0 architecture put it at a significant disadvantage. While it has a wider 256-bit memory bus, the slower GDDR5 memory limits its bandwidth to less than half of the RX 6800M's.

For anyone selecting a GPU for gaming, content creation, or general-purpose computing, the RX 6800M is the only logical choice between the two. Its 74th percentile ranking among all GPUs versus the FirePro's 73rd percentile confirms that it is not just better than the older card, but also places higher in the overall performance hierarchy. The FirePro S7150's nearest rival is the NVIDIA GeForce GTX 980 Ti, a high-end card from its own era, but it still cannot match the modern RX 6800M. The data suggests the FirePro S7150 should only be considered if a specific legacy server application requires its exact feature set and form factor. For all other purposes, the RX 6800M wins decisively.
