Architecture Differences

The architectural gap between these two GPUs is substantial, reflecting nearly a full generational leap in design philosophy. The RX 6700 is built on RDNA 2.0, AMD’s modern gaming-oriented architecture, fabricated on TSMC’s 7 nm process. It packs 17,200 million transistors into a 335 mm² die, yielding a transistor density of 51.3M per mm². In contrast, the FirePro S7150 uses the older GCN 3.0 architecture on a 28 nm process, with 5,000 million transistors spread across a larger 366 mm² die, resulting in a much lower density of 13.7M per mm².

The RX 6700’s compute layout is significantly more robust. It features 2304 shading units, 144 texture mapping units, and 64 ROPs. The FirePro S7150 has 2048 shading units, 128 TMUs, and only 32 ROPs. The RX 6700 also includes 36 dedicated ray tracing cores, a feature entirely absent from the FirePro S7150. This RT core presence gives the RX 6700 access to DirectX 12 Ultimate (12_2) API support, whereas the FirePro S7150 is limited to DirectX 12 (12_0).

The memory subsystem differs fundamentally. The RX 6700 uses 10 GB of GDDR6 on a 160-bit interface, achieving 320.0 GB/s bandwidth. The FirePro S7150 uses 8 GB of GDDR5 on a wider 256-bit bus but manages only 160.0 GB/s due to slower memory clocks. The RX 6700’s memory runs at 2000 MHz (16 Gbps effective), while the FirePro S7150’s memory operates at 1250 MHz (5 Gbps effective).

Pixel and texture throughput also diverge sharply. The RX 6700 achieves 156.8 GPixel/s and 352.8 GTexel/s, versus 29.44 GPixel/s and 117.8 GTexel/s for the FirePro S7150. The RX 6700’s FP16 performance is 22.58 TFLOPS (2:1 ratio), compared to 7.537 TFLOPS on the FirePro S7150. The interface and power delivery also differ: the RX 6700 uses PCIe 4.0 x16 with a 1x 8-pin connector, while the FirePro S7150 uses PCIe 3.0 x16 with a 1x 6-pin connector. The RX 6700 is dual-slot and has display outputs (1x HDMI 2.1, 3x DisplayPort 1.4a); the FirePro S7150 is single-slot with no display outputs, indicating its server-oriented design.

The Verdict

The data clearly favors the AMD Radeon RX 6700 in nearly every measurable category. Its average benchmark score of 30433 places it 8.2% above the FirePro S7150’s 28117. The RX 6700 wins both head-to-head benchmark tests decisively, with a 268.6% lead in Geekbench OpenCL and a 182.8% lead in Geekbench Vulkan. This performance gap is consistent with the underlying hardware: the RX 6700 has 3x the FP32 throughput, double the memory bandwidth, and nearly 3.5x the transistor count.

The RX 6700 also has a higher percentile ranking (75th versus 73rd), indicating it outperforms a larger fraction of the GPU population. Its nearest rivals include the NVIDIA CMP 70HX (0.1% faster) and the AMD Radeon RX 6800 (1.1% slower), positioning it as a competitive mid-to-high-end part. The FirePro S7150’s nearest rivals include the NVIDIA GeForce GTX 980 Ti (0.3% slower) and the AMD Radeon Pro W5500X (0.5% faster), showing it competes in a lower performance tier.

Who should pick which? The RX 6700 is the clear choice for any workload that benefits from modern DirectX 12 Ultimate features, ray tracing, or high-bandwidth memory. Its 10 GB GDDR6 buffer and 320.0 GB/s bandwidth make it suitable for gaming and general-purpose compute. The FirePro S7150, with its 8 GB GDDR5 and 160.0 GB/s bandwidth, is an older server-oriented card with no display outputs, making it unsuitable for client-side rendering. The launch MSRP of the FirePro S7150 was 2,399 USD, but its benchmark results do not justify that positioning against the RX 6700’s superior specifications. For any modern application, the RX 6700 is the superior choice based on the available data.

Head-to-Head Benchmarks

The head-to-head benchmark data provides a stark illustration of the generational performance gap between these two cards. In Geekbench OpenCL, the RX 6700 scores 97841, while the FirePro S7150 manages only 26543. This represents a 268.6% advantage for the RX 6700, meaning it delivers roughly 3.7x the OpenCL compute performance. This result is consistent with the FP32 throughput difference, where the RX 6700’s 11.29 TFLOPS dwarfs the FirePro S7150’s 3.768 TFLOPS. The OpenCL test stresses raw compute parallelism, and the RX 6700’s higher shading unit count combined with its newer architecture and faster memory bandwidth clearly dominates.

In Geekbench Vulkan, the gap narrows slightly but remains enormous. The RX 6700 scores 83974 versus 29690 for the FirePro S7150, an 182.8% advantage. Vulkan is a lower-level API that can better utilize the FirePro S7150’s GCN architecture, but the RX 6700 still more than doubles the FirePro S7150’s score. The RX 6700’s support for Vulkan 1.4 (versus 1.2.170 on the FirePro S7150) may contribute to better driver-level optimization, but the fundamental hardware advantages are the primary driver.

Beyond the two direct comparisons, the broader benchmark suite for the RX 6700 reveals consistent strength across different APIs. It scores 2014 in 3DMark Steel Nomad DX12, 122223 in Geekbench Metal, and 18931 in Passmark G3D. The Passmark tests show a wide range: 250 in DirectX 9, 166 in DirectX 11, 115 in DirectX 10, and 71 in DirectX 12. The GPU compute score of 8240 and G2D score of 936 round out the profile. These results are only available for the RX 6700, as the FirePro S7150’s benchmark data is limited to Geekbench OpenCL and Vulkan.

The wins tally reflects this dominance: the RX 6700 wins 2 out of 2 head-to-head benchmarks, with the FirePro S7150 winning none. The average score difference of 2316 points (30433 versus 28117) further reinforces that the RX 6700 is the stronger performer overall, even when considering the FirePro S7150’s narrower benchmark coverage. The RX 6700’s nearest rival, the NVIDIA CMP 70HX, is just 0.1% faster, while the FirePro S7150’s closest competitor, the GeForce GTX 980 Ti, is 0.3% slower, indicating that the RX 6700 operates in a higher performance stratum than the FirePro S7150.
