AMD FirePro W5100 vs AMD Radeon RX 7800 XT Comparison

AMD Radeon RX 7800 XT and AMD FirePro W5100 are two GPUs from different eras and market segments, separated by nearly a decade of architectural evolution. The RX 7800 XT, built on RDNA 3.0, is a modern enthusiast-class card, while the FirePro W5100 is a legacy workstation product based on GCN 2.0. Benchmark data reveals an absolute performance hierarchy, but the specific strengths of each card are worth examining for distinct use cases.

Where Each One Wins

The data shows a stark contrast in benchmark coverage and results. The AMD Radeon RX 7800 XT wins both head-to-head benchmark comparisons, asserting dominance in modern API workloads. In the Geekbench OpenCL test, the RX 7800 XT scores 18290, which is 53.9% higher than the FirePro W5100’s 11888. This substantial lead in a compute-oriented API indicates a significant advantage in general-purpose GPU computing tasks. The margin widens dramatically in the Geekbench Vulkan test, where the RX 7800 XT scores 54228 compared to the FirePro W5100’s 13805, a staggering 292.8% difference. This demonstrates that the RX 7800 XT is overwhelmingly superior in modern, low-level graphics and compute APIs.

The FirePro W5100’s only available benchmark scores are in OpenCL and Vulkan, where it trails significantly. However, its profile suggests a different historical context. With a 50 W TDP and no power connectors, it was designed for power-constrained environments. Its single-slot form factor and four DisplayPort 1.2 outputs point to a multi-display workstation use case, not raw performance. While it loses all head-to-head tests, its niche is defined by its physical and power characteristics rather than its benchmark scores. The RX 7800 XT, with a 263 W TDP and dual-slot design, is a performance-first card that wins every benchmark it participates in.

The head-to-head data is limited to two tests, but the RX 7800 XT’s broader benchmark suite shows its versatility. It posts a Passmark G3D score of 24176 and a Passmark GPU Compute score of 13473, while the FirePro W5100 has no comparable scores in these tests. The RX 7800 XT also supports DirectX 12 Ultimate (12_2), whereas the FirePro W5100 is limited to DirectX 12 (12_0). This API support difference is a clear win for the newer card in modern gaming and graphics applications.

The Verdict

The verdict is unambiguous based on the performance data. For any user prioritizing raw computational power, modern API support, or gaming performance, the AMD Radeon RX 7800 XT is the only logical choice. It wins both head-to-head benchmarks by significant margins, with a 53.9% lead in OpenCL and a 292.8% lead in Vulkan. Its architecture, RDNA 3.0 on a 5 nm process, delivers 37.32 TFLOPS of FP32 performance, dwarfing the FirePro W5100’s 1,428.5 GFLOPS. The RX 7800 XT also offers 16 GB of GDDR6 memory with 624.1 GB/s bandwidth, compared to 4 GB of GDDR5 with 96.00 GB/s on the FirePro W5100.

The FirePro W5100 is an end-of-life product with no benchmark wins to its name. Its only potential advantage is its low power draw of 50 W and single-slot design, which could be relevant for legacy systems or specific multi-card configurations. However, its 4 GB memory capacity and 128-bit bus width severely limit its utility in modern workloads. The data suggests that the FirePro W5100 is obsolete for any performance-critical task. Its percentile rank of 52 versus the RX 7800 XT’s 51 is a statistical artifact of different benchmark pools, not an indicator of comparable performance. In direct comparison, the RX 7800 XT is the clear winner for any modern application, from gaming to compute.

Head-to-Head Benchmarks

The head-to-head benchmark results are decisive and require little interpretation. In the Geekbench OpenCL test, the RX 7800 XT scores 18290, while the FirePro W5100 manages 11888. The 53.9% delta highlights the computational advantage of the newer card, which has 3840 shading units versus 768 on the FirePro W5100. This translates directly to higher throughput in parallel compute tasks.

The Geekbench Vulkan test is where the gap becomes truly enormous. The RX 7800 XT scores 54228, while the FirePro W5100 scores just 13805. The 292.8% delta reflects the architectural leap from GCN 2.0 to RDNA 3.0. Vulkan’s low-level nature allows the RX 7800 XT to leverage its 60 RT cores and 240 TMUs effectively, whereas the FirePro W5100’s older architecture struggles with modern API overhead. This result indicates that the RX 7800 XT is not just faster, but disproportionately faster in modern workloads that the FirePro W5100 was never designed to handle efficiently.

Beyond these two tests, the RX 7800 XT has a full suite of benchmarks where the FirePro W5100 has no data. For example, the RX 7800 XT scores 4157 in 3DMark Steel Nomad DX12 and 24176 in Passmark G3D. These scores, while not directly comparable to the FirePro W5100, paint a picture of a card that is competitive with modern mid-range GPUs. The FirePro W5100’s absence from these tests reinforces its status as a legacy product.

Architecture Differences

The architectural differences between these two GPUs are foundational and explain the massive performance gap. The AMD Radeon RX 7800 XT is built on the Navi 32 chip using the RDNA 3.0 architecture, a modern design that emphasizes efficiency and high clock speeds. It is fabricated on a 5 nm process at TSMC, allowing for 28,100 million transistors on a 346 mm² die, resulting in a transistor density of 81.2M / mm². The FirePro W5100, in contrast, uses the Bonaire chip with the GCN 2.0 architecture, a much older design. It is fabricated on a 28 nm process, with 2,080 million transistors on a 160 mm² die, giving a transistor density of only 13.0M / mm². This generational leap in manufacturing and design is a primary driver of the performance difference.

The memory subsystems are also vastly different. The RX 7800 XT features 16 GB of GDDR6 memory on a 256-bit bus, delivering 624.1 GB/s of bandwidth. The FirePro W5100 has 4 GB of GDDR5 memory on a 128-bit bus, providing 96.00 GB/s. This 6.5x bandwidth advantage allows the RX 7800 XT to feed its 3840 shading units and 240 TMUs far more effectively. The FirePro W5100’s 768 shading units and 48 TMUs are severely limited by its memory bandwidth.

Compute capabilities further separate the two. The RX 7800 XT delivers 37.32 TFLOPS of FP32 performance, while the FirePro W5100 delivers 1,428.5 GFLOPS. The RX 7800 XT also has dedicated 60 RT cores for ray tracing, a feature entirely absent from the FirePro W5100. The newer card supports PCIe 4.0 x16, while the FirePro W5100 uses PCIe 3.0 x16. Display outputs also differ, with the RX 7800 XT offering 1x HDMI 2.1a and 3x DisplayPort 2.1, while the FirePro W5100 offers 4x DisplayPort 1.2. Finally, the RX 7800 XT supports Vulkan 1.4, while the FirePro W5100 supports Vulkan 1.2.170, further cementing the modern card’s advantage in contemporary software environments.
