AMD FirePro W5100 vs AMD Radeon RX 9070 XT Comparison

# AMD Radeon RX 9070 XT vs AMD FirePro W5100

The AMD Radeon RX 9070 XT and AMD FirePro W5100 represent two entirely different eras of GPU design. The RX 9070 XT is a modern RDNA 4.0 flagship built on TSMC's 4 nm process, while the FirePro W5100 is a legacy GCN 2.0 workstation card from 2014 fabricated on 28 nm. The benchmark data shows a staggering generational gap: the RX 9070 XT leads by 46.6% in OpenCL and by 377.2% in Vulkan, with the newer card averaging 13,543 points across all tests versus 12,847 for the older FirePro. These are not competing products in any practical sense, but the comparison highlights how far GPU architecture has advanced in roughly a decade.

FAQ

Q: What is the production status of each card?

A: The RX 9070 XT is listed as "Active" production, released on March 5, 2025. The FirePro W5100 is "End-of-life" production, released on March 30, 2014, with its successor being the Radeon Pro Polaris.

Q: How do the power requirements compare?

A: The RX 9070 XT has a 304 W TDP and requires a 700 W suggested power supply with dual 8-pin connectors. The FirePro W5100 draws only 50 W, needs a 250 W PSU, and requires no external power connectors.

Architecture Differences

The architectural gap between these two AMD cards is immense. The RX 9070 XT uses the Navi 48 chip built on RDNA 4.0 architecture, manufactured on TSMC's 4 nm process. It packs 53,900 million transistors into a 357 mm² die, yielding a transistor density of 151.0 million per square millimeter. The FirePro W5100 uses the Bonaire chip with GCN 2.0 architecture, fabricated on a 28 nm process. It contains just 2,080 million transistors on a 160 mm² die, with a density of 13.0 million per square millimeter — a 25.9 million transistor-per-square-millimeter difference that underscores the process node advantage.

The RX 9070 XT belongs to the Navi IV (RX 9000) generation, succeeding the Navi III architecture. The FirePro W5100 is from the FirePro GCN (Wx100) generation, succeeding FirePro Terascale. Clock speeds tell a similar story: the RX 9070 XT boosts to 2970 MHz with a 1660 MHz base clock and a 2400 MHz game clock, while the FirePro W5100 has no listed base or boost clocks, only a memory clock of 1500 MHz (6 Gbps effective). The newer card also supports PCIe 5.0 x16, whereas the FirePro W5100 uses PCIe 3.0 x16.

Feature support diverges sharply. The RX 9070 XT supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, plus hardware ray tracing via 64 dedicated RT cores. The FirePro W5100 tops out at DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170, with no ray tracing capability. Display outputs also differ: the RX 9070 XT offers 1x HDMI 2.1b and 3x DisplayPort 2.1a, while the FirePro W5100 provides 4x DisplayPort 1.2.

Where Each One Wins

The RX 9070 XT wins every shared benchmark in this comparison, so the "where each one wins" split is heavily one-sided. Still, the nature of the wins matters. In Geekbench OpenCL, the RX 9070 XT posts 17,428 points versus 11,888 for the FirePro W5100 — a 46.6% lead. This is a compute-oriented workload that stresses raw FP32 throughput, where the newer card's 48.66 TFLOPS dwarfs the FirePro W5100's 1,428.5 GFLOPS. For general-purpose GPU compute, the RX 9070 XT is clearly the tool for the job.

The Vulkan gap is even more pronounced: 65,879 points for the RX 9070 XT versus 13,805 for the FirePro W5100, a 377.2% advantage. Vulkan is a modern low-level API that benefits from newer hardware features, better driver optimization, and higher memory bandwidth. The RX 9070 XT's 644.6 GB/s bandwidth and 16 GB frame buffer give it massive headroom for large datasets and high-resolution textures, whereas the FirePro W5100's 96.00 GB/s and 4 GB capacity become bottlenecks quickly.

The FirePro W5100 does retain advantages in physical footprint and power draw. It is a single-slot card measuring 173 mm by 111 mm, requiring no external power connectors and only a 250 W PSU. The RX 9070 XT is a dual-slot card needing 2x 8-pin connectors and a 700 W PSU. For legacy workstation environments with tight power budgets or space constraints, the FirePro W5100 remains usable, but it cannot compete on raw performance.

Head-to-Head Benchmarks

The two shared benchmarks in the data paint a clear picture of generational dominance. In Geekbench OpenCL, the RX 9070 XT scores 17,428 points, beating the FirePro W5100's 11,888 points by 46.6%. This is a substantial margin but not an overwhelming one compared to the Vulkan result. OpenCL is a mature compute API that both cards support reasonably well, and the FirePro W5100's GCN architecture was designed with compute workloads in mind. Still, the RX 9070 XT's far higher shading unit count (4,096 versus 768), combined with 8x the TMUs and 8x the ROPs, drives a decisive win.

The Geekbench Vulkan test shows the true chasm between these two products. The RX 9070 XT achieves 65,879 points, while the FirePro W5100 manages just 13,805 points — a 377.2% delta. This is not a marginal improvement; it is a 4.77x performance advantage for the newer card. Vulkan's low-level nature rewards hardware designed for modern graphics pipelines, including dedicated ray tracing cores, higher memory bandwidth, and faster clock speeds. The FirePro W5100, with its 28 nm process and 2014-era architecture, simply cannot keep pace with the RX 9070 XT's RDNA 4.0 design.

Beyond the shared benchmarks, the RX 9070 XT has a much broader test portfolio. It records scores of 7,260 in 3DMark Steel Nomad DX12, 154 in Passmark DirectX 10, 292 in DirectX 11, 78 in DirectX 12, 353 in DirectX 9, 1,328 in Passmark G2D, 26,795 in G3D, and 15,864 in GPU Compute. The FirePro W5100 has no entries for these tests, so direct comparison is impossible, but the RX 9070 XT's wins tally stands at 2-0 across all head-to-head benchmarks. The nearest rivals to the RX 9070 XT — the AMD Radeon HD 7770M, NVIDIA GeForce GTX 570, NVIDIA P106-090, and AMD Radeon Pro 555 — all sit within 1% of its average score, placing it in a crowded mid-range performance tier despite its flagship positioning. The FirePro W5100's nearest rivals, including the AMD Radeon Pro 455 and NVIDIA GeForce GTX 590, also cluster within 0.6%, showing that the older card remains competitive with its own generation's peers.
