AMD FirePro S7150 vs AMD Radeon RX 7900 GRE Comparison

Head-to-Head Benchmarks

The benchmark data shows a decisive performance advantage for the AMD Radeon RX 7900 GRE across the two recorded head-to-head tests. The most striking result is in Geekbench OpenCL, where the RX 7900 GRE scores 175,758 points against the FirePro S7150's 26,543 points. This represents a 562.2% delta, meaning the newer card delivers more than six times the raw compute throughput in this workload. The margin is so large that it separates not just generations but entire performance tiers.

In the Vulkan API test, the gap narrows somewhat but remains overwhelming. The RX 7900 GRE posts a score of 99,850, while the FirePro S7150 manages 29,690. The delta here is 236.3%, indicating that even in a lower-level graphics API where the older GCN architecture might theoretically show relative strength, the RDNA 3.0 part still more than triples the older card's output. This suggests that the architectural improvements go beyond simple clock speed or core count advantages, affecting fundamental execution efficiency.

Looking at the broader database averages, the RX 7900 GRE holds an average benchmark score of 32,456 across all recorded tests, while the FirePro S7150 averages 28,117. That 15.4% difference in overall standing is smaller than the head-to-head deltas, which is expected given that the FirePro's nearest rivals include the NVIDIA GeForce GTX 980 Ti (28,020, +0.3%) and the AMD Radeon Pro W5500X (27,973, +0.5%). Meanwhile, the RX 7900 GRE sits in a different competitive neighborhood entirely, with rivals like the AMD FirePro S10000 (32,388, +0.2%) and the AMD Radeon RX 590 GME (32,601, -0.4%) clustering around its average. The percentile ranks confirm this: the RX 7900 GRE sits at the 77th percentile of all GPUs, while the FirePro S7150 sits at the 73rd percentile.

The wins tally shows the RX 7900 GRE taking both recorded head-to-head contests, with the FirePro S7150 recording zero victories. This is not a close matchup; it is a generational gap expressed in every available metric. Even the FirePro's strongest individual result, its Geekbench OpenCL score of 26,543, falls short of the RX 7900 GRE's Vulkan score by a factor of 3.7, which illustrates how far ahead the newer architecture is across different API paths.

Architecture Differences

The two cards represent fundamentally different eras of AMD GPU design. The RX 7900 GRE uses the Navi 31 chip built on TSMC's 5 nm process, featuring the RDNA 3.0 architecture under the codename "Plum Bonito." In contrast, the FirePro S7150 uses the Tonga chip on a 28 nm process, based on the older GCN 3.0 architecture.

The transistor counts tell a dramatic story. The Navi 31 chip packs 57,700 million transistors into a 529 mm² die, achieving a transistor density of 109.1 million per square millimeter. The Tonga chip, by comparison, contains 5,000 million transistors on a 366 mm² die, with a density of just 13.7 million per square millimeter. That is an 8-fold difference in density, reflecting both the process node advantage and the architectural efficiency gains of RDNA 3.0.

The compute resources differ massively. The RX 7900 GRE has 5,120 shading units, 320 texture mapping units, and 160 render output units. It also includes 80 ray tracing cores, a feature entirely absent from the FirePro S7150, which has no ray tracing hardware at all. The older card has 2,048 shading units, 128 TMUs, and only 32 ROPs. This means the RX 7900 GRE has 2.5 times the shading units, 2.5 times the TMUs, and 5 times the ROPs of its predecessor.

Memory configurations diverge equally. The RX 7900 GRE uses 16 GB of GDDR6 memory on a 256-bit bus, delivering 576.0 GB/s of bandwidth. The FirePro S7150 has 8 GB of GDDR5 on the same 256-bit bus, but only achieves 160.0 GB/s. The newer card's memory clock runs at 2250 MHz (18 Gbps effective) versus 1250 MHz (5 Gbps effective) for the older part. This 3.6-fold bandwidth advantage matters significantly for texture-heavy workloads and large dataset processing.

The pixel and texture rates reflect the hardware differences. The RX 7900 GRE achieves 359.2 GPixel/s and 718.4 GTexel/s, while the FirePro S7150 manages 29.44 GPixel/s and 117.8 GTexel/s. Floating point performance shows a 12.2-fold gap in FP32: 45.98 TFLOPS versus 3.768 TFLOPS. Even FP16, where the FirePro S7150's 7.537 TFLOPS is respectable for its generation, is dwarfed by the RX 7900 GRE's 91.96 TFLOPS.

API support also differs. The RX 7900 GRE supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the FirePro S7150 only reaches DirectX 12 (12_0) and Vulkan 1.2.170. OpenGL support is identical at 4.6. The newer card also supports modern display outputs including HDMI 2.1a, DisplayPort 2.1, and USB Type-C, whereas the FirePro S7150 has no display outputs at all, being a server-focused product.

The Verdict

The data is unambiguous: the AMD Radeon RX 7900 GRE is the superior performer in every recorded benchmark. Its 562.2% lead in OpenCL and 236.3% lead in Vulkan place it in a completely different performance class. Anyone choosing between these two for compute workloads, rendering, or any GPU-accelerated task should select the RX 7900 GRE without hesitation, assuming the system can accommodate its dual-slot form factor and higher power requirements.

The FirePro S7150's only advantages are physical and power related. It is a single-slot card with a 150 W TDP and a single 6-pin connector, versus the RX 7900 GRE's dual-slot design, 260 W TDP, and dual 8-pin connectors. The older card also uses a PCIe 3.0 x16 interface compared to PCIe 4.0 x16, making it easier to integrate into older systems. However, these are not performance advantages; they are compatibility considerations.

For server deployments where the FirePro S7150's lack of display outputs and lower power envelope might be attractive, the RX 7900 GRE still offers better compute density per watt. The newer card delivers 45.98 TFLOPS at 260 W (approximately 177 GFLOPS per watt) versus 3.768 TFLOPS at 150 W (approximately 25 GFLOPS per watt). The efficiency gap is larger than the raw performance gap, reinforcing that the RX 7900 GRE is not just faster but fundamentally more efficient.

The production status further clarifies the choice. The RX 7900 GRE is listed as "Active" while the FirePro S7150 is "End-of-life." The FirePro S7150's successor is listed as "Radeon Pro GCN," and its predecessor is "FirePro Terascale," placing it in a discontinued product line. The RX 7900 GRE's successor is "Navi IV," indicating an ongoing product roadmap. For any new purchase, the RX 7900 GRE is the only sensible selection based on the recorded data.
