AMD FirePro S7150 vs AMD Radeon RX 6800S Comparison

Where Each One Wins

The recorded benchmark data splits cleanly between the two AMD parts, with the Radeon RX 6800S taking both available head-to-head victories. The FirePro S7150 does not win any of the compared tests, making the RX 6800S the clear performance leader in the database's direct comparisons.

The RX 6800S dominates in synthetic compute workloads. In Geekbench OpenCL, it scores 73,202 against the FirePro S7150's 26,543, a 63.7% margin. The Vulkan test shows a similar pattern: 81,272 versus 29,690, a 63.5% gap. These are not narrow wins; the RX 6800S more than doubles the FirePro S7150's output in both API-level benchmarks.

The FirePro S7150, however, occupies a different niche in the product stack. It is a server-oriented card with no display outputs, designed for compute deployments rather than interactive graphics. Its 73rd percentile ranking among all GPUs places it near the NVIDIA GeForce GTX 980 Ti (0.3% delta) and AMD Radeon Pro W5500X (0.5% delta), indicating it sits in the upper-middle tier of overall GPU performance despite its age.

The RX 6800S, a mobile part with a 69th percentile ranking, finds itself surrounded by different rivals: the NVIDIA GeForce RTX 2080 SUPER (0.4% behind), the GTX 780 Ti (0.7% ahead), and the AMD Radeon RX 9070 (0.8% ahead). Its average benchmark score of 24,063 is lower than the FirePro S7150's 28,117, but the RX 6800S wins every test where both cards have recorded data.

For users choosing between these two, the decision hinges on workload type. The RX 6800S excels in compute-heavy tasks and modern API performance. The FirePro S7150, with its server heritage and compatibility with older GCN-era software stacks, may still serve specific datacenter roles, but the database shows no benchmark where it outperforms the newer mobile part.

Head-to-Head Benchmarks

The database contains two direct comparisons between these GPUs, and the RX 6800S wins both by substantial margins.

In Geekbench OpenCL, the RX 6800S posts 73,202 points. The FirePro S7150 manages 26,543. The delta is 63.7% in favor of the RX 6800S. This test exercises general-purpose compute across a range of workloads, and the newer RDNA 2 architecture's higher FP32 throughput (8.602 TFLOPS versus 3.768 TFLOPS) explains much of the gap.

The Geekbench Vulkan result follows the same pattern. The RX 6800S scores 81,272, while the FirePro S7150 scores 29,690, a 63.5% difference. Vulkan overhead and driver optimization favor the RX 6800S, which also has access to hardware ray tracing cores (32 RT cores) and a newer API version (Vulkan 1.4 versus 1.2.170).

The FirePro S7150's closest rival in the database is the GTX 980 Ti, with an average score of 28,020, just 0.3% behind. The RX 6800S's closest rival is the RTX 2080 SUPER at 24,170, 0.4% behind. This means the RX 6800S, despite winning both head-to-head tests, ranks slightly lower overall because its other benchmark results (e.g., Passmark DirectX 9 at 200, DirectX 11 at 139, G2D at 732) drag down its average.

In terms of raw compute, the RX 6800S delivers 8.602 TFLOPS FP32 and 17.20 TFLOPS FP16 (2:1). The FirePro S7150 delivers 3.768 TFLOPS FP32 and 7.537 TFLOPS FP16 (2:1). The RX 6800S also doubles the pixel rate (134.4 GPixel/s versus 29.44 GPixel/s) and texture rate (268.8 GTexel/s versus 117.8 GTexel/s). These numbers align with the benchmark results: the RX 6800S is roughly 2.3x faster in FP32 and 2.3x faster in FP16, matching the observed benchmark deltas.

Specification Differences

The two cards differ across nearly every hardware specification. The most striking contrast is the process node: the FirePro S7150 uses a 28 nm process with 5,000 million transistors on a 366 mm² die, while the RX 6800S uses a 7 nm process with 11,060 million transistors on a 237 mm² die. The transistor density reflects this: 13.7M per mm² for the FirePro, 46.7M per mm² for the RX 6800S.

Clock speeds differ significantly. The FirePro S7150 has no listed base or boost clock, only a memory clock of 1250 MHz (5 Gbps effective). The RX 6800S has a base clock of 1800 MHz, a game clock of 1975 MHz, a boost clock of 2100 MHz, and a memory clock of 2000 MHz (16 Gbps effective).

Memory interfaces diverge: the FirePro S7150 uses GDDR5 with a 256-bit bus and 160.0 GB/s bandwidth; the RX 6800S uses GDDR6 with a 128-bit bus and 256.0 GB/s bandwidth. Both have 8 GB capacity.

The compute units are identical in shading units (2048) and texture mapping units (128), but the ROP count doubles on the RX 6800S: 64 versus 32. The RX 6800S also adds 32 ray tracing cores, which the FirePro S7150 lacks entirely.

Power and physical design differ substantially. The FirePro S7150 is a single-slot card with a 150 W TDP, one 6-pin power connector, a suggested 450 W PSU, and dimensions of 241 mm length and 111 mm height. The RX 6800S is an integrated graphics processor (IGP) with a 100 W TDP, no power connectors, no suggested PSU, and no listed dimensions.

Bus interfaces also differ: PCIe 3.0 x16 for the FirePro S7150, PCIe 4.0 x8 for the RX 6800S. Display outputs are "No outputs" for the FirePro S7150 and "Portable Device Dependent" for the RX 6800S.

The FirePro S7150 has a launch MSRP of 2,399 USD; the RX 6800S has no recorded launch MSRP.

Architecture Differences

The architectural divide is generational. The FirePro S7150 uses the Tonga chip built on GCN 3.0, while the RX 6800S uses the Navi 23 chip built on RDNA 2.0. These are fundamentally different designs with different strengths.

GCN 3.0, introduced in 2015, was AMD's compute-first architecture. It prioritized raw throughput in workloads that could utilize its wide vector units. The FirePro S7150's 2048 shading units, 128 TMUs, and 32 ROPs represent a balanced design for its era, but the architecture lacks dedicated ray tracing hardware and relies on older API support (DirectX 12_0, Vulkan 1.2.170).

RDNA 2.0, released in 2020, represents a major redesign. It features a unified cache hierarchy, higher clock speeds, and dedicated ray tracing cores (32 on this chip). The RX 6800S supports DirectX 12 Ultimate (12_2), which includes features like mesh shaders and variable rate shading, and Vulkan 1.4, a much newer API revision than the FirePro's 1.2.170.

The FP32 and FP16 ratios tell a story of efficiency. The FirePro S7150 achieves 3.768 TFLOPS FP32 and 7.537 TFLOPS FP16 (2:1) from a 150 W TDP. The RX 6800S achieves 8.602 TFLOPS FP32 and 17.20 TFLOPS FP16 (2:1) from a 100 W TDP. That is 2.3x the compute at two-thirds the power draw, a direct result of the 7 nm process and architectural improvements.

The RX 6800S's 32 ROPs versus 64 ROPs on the FirePro S7150 seems counterintuitive, but the RX 6800S's higher clock speeds (2100 MHz boost versus no listed boost for the FirePro) and memory bandwidth (256.0 GB/s versus 160.0 GB/s) compensate. The pixel rate of 134.4 GPixel/s on the RX 6800S is 4.6x higher than the FirePro's 29.44 GPixel/s.

The FirePro S7150 belongs to the FirePro Server (Sx100) generation, succeeding FirePro Terascale and preceding Radeon Pro GCN. The RX 6800S belongs to the Navi Mobile (RX 6000M) generation, succeeding Polaris Mobile. These lineage differences explain the target use cases: datacenter compute for the FirePro, high-performance mobile graphics for the RX 6800S.
