AMD FirePro W7100 vs AMD Radeon RX 9070 Comparison

The AMD FirePro W7100 and AMD Radeon RX 9070 represent two vastly different eras of GPU design. The data shows a generational chasm, with the RX 9070 delivering benchmark scores that dwarf the older workstation card. In the two shared head-to-head tests, the RX 9070 wins decisively, but the nature of those wins reveals much about the architectural shift between 2014 and 2025.

Head-to-Head Benchmarks

The most dramatic disparity appears in the Geekbench OpenCL test. The AMD Radeon RX 9070 scores 131,539, while the AMD FirePro W7100 manages only 24,182. That is a deltaPct of -81.6%, meaning the RX 9070 is roughly 5.4 times faster in raw compute throughput. This is not a marginal improvement; it is a complete obliteration of the older card's performance ceiling. The 36.13 TFLOPS FP32 figure for the RX 9070 versus the FirePro's 3.297 TFLOPS explains this gap quantitatively—the newer card has over ten times the theoretical floating-point capacity.

The Vulkan API test tells a similar story, though with a narrower margin. The RX 9070 posts 58,705, against the W7100's 27,529, a deltaPct of -53.1%. Still a decisive victory for the RX 9070, but the smaller gap suggests the FirePro's GCN 3.0 architecture handles Vulkan's low-level overhead better than its OpenCL performance would imply. Interestingly, the RX 9070's Vulkan score is less than half its OpenCL score, whereas the W7100's Vulkan result is actually higher than its OpenCL result. This inversion hints that the older architecture's driver stack or hardware scheduler was better optimized for Vulkan's command buffer model relative to its compute workloads.

The RX 9070's nearest rivals in the database—including the NVIDIA GeForce GTX TITAN Z at a 0.6% deltaPct and the AMD Radeon RX 6800S at -0.8%—show that its average benchmark score of 23,877 places it in a competitive mid-range tier. The FirePro W7100, with an average of 25,856, sits slightly higher in its own peer group, trailing the AMD FirePro D700 by just 0.1%. Neither card is a top-tier performer in the absolute database rankings, but the RX 9070's individual test scores are in a completely different league from the W7100's.

Architecture Differences

The fundamental gap lies in the manufacturing process and transistor budget. The FirePro W7100 uses a 28 nm node at TSMC, packing 5,000 million transistors into a 366 mm² die. The RX 9070 shrinks to a 4 nm node, cramming 53,900 million transistors into a nearly identical 357 mm² die. That is a 10.8x increase in transistor count on essentially the same physical footprint, enabled by a jump in transistor density from 13.7M per mm² to 151.0M per mm².

Architecturally, the W7100 runs GCN 3.0 with the Tonga chip, while the RX 9070 uses RDNA 4.0 with Navi 48. The compute unit layout reflects this: the RX 9070 has 3,584 shading units, exactly double the W7100's 1,792. Texture mapping units also double from 112 to 224, but the ROP count quadruples from 32 to 128. This 4x increase in ROPs directly explains the pixel rate jump from 29.44 GPixel/s to 322.6 GPixel/s—a 10.9x improvement that outpaces even the shading unit growth. The texture rate similarly explodes from 103.0 GTexel/s to 564.5 GTexel/s.

Memory architecture shows a similar generational leap. The W7100 uses 8 GB of GDDR5 on a 256-bit bus, yielding 160.0 GB/s bandwidth. The RX 9070 doubles capacity to 16 GB of GDDR6, keeps the 256-bit bus, but pushes bandwidth to 644.6 GB/s—a 4.0x increase. Memory clocks tell part of the story: 1250 MHz (5 Gbps effective) on the W7100 versus 2518 MHz (20.1 Gbps effective) on the RX 9070. The RX 9070 also introduces 56 dedicated ray tracing cores, a feature entirely absent from the GCN 3.0 design.

The RX 9070's boost clock of 2520 MHz, with a game clock of 2070 MHz and base of 1330 MHz, stands against the W7100's unlisted boost and base clocks—the data only provides a memory clock for the older card. The FirePro's lack of specified core clocks suggests a conservative fixed-frequency design typical of early workstation parts. Power requirements scale accordingly: 220 W TDP with dual 8-pin connectors for the RX 9070 versus 150 W with a single 6-pin for the W7100. The RX 9070 also demands a PCIe 5.0 x16 interface, quadrupling the W7100's PCIe 3.0 x16 bandwidth.

FAQ

Q: Which card has better raw compute performance in OpenCL?

A: The AMD Radeon RX 9070 dominates, scoring 131,539 in Geekbench OpenCL versus the AMD FirePro W7100's 24,182. This represents an 81.6% delta in favor of the RX 9070, consistent with its 36.13 TFLOPS FP32 rating versus 3.297 TFLOPS.

Q: Is the RX 9070's Vulkan advantage as large as its OpenCL lead?

A: No. The RX 9070 wins Vulkan 58,705 to 27,529, a 53.1% delta. The W7100's Vulkan score is actually higher than its OpenCL score, suggesting relative strength in that API, but the RX 9070 still holds a commanding lead.

Q: How do the memory systems compare?

A: The RX 9070 offers 16 GB GDDR6 with 644.6 GB/s bandwidth on a 256-bit bus. The W7100 has 8 GB GDDR5 with 160.0 GB/s on the same bus width. The RX 9070's effective memory speed of 20.1 Gbps is four times the W7100's 5 Gbps.

Q: What architectural feature does the RX 9070 have that the W7100 completely lacks?

A: The RX 9070 includes 56 ray tracing cores, which the GCN 3.0-based W7100 does not have. This is a fundamental hardware difference for real-time ray tracing workloads.

Q: Which card has better API support for modern games?

A: The RX 9070 supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the W7100 only reaches DirectX 12 (12_0) and Vulkan 1.2.170. Both support OpenGL 4.6.

Q: How do their production statuses differ?

A: The W7100 is end-of-life, released in August 2014, while the RX 9070 is active, released in March 2025. The RX 9070 has a successor listed as none, while the W7100's successor is the Radeon Pro Polaris.

The Verdict

The data points to an unambiguous conclusion: the AMD Radeon RX 9070 is the superior GPU by every measurable benchmark metric. It wins both head-to-head tests with deltas of -81.6% and -53.1%, offers 4x the memory capacity, 4x the bandwidth, and 10.9x the pixel rate. The RX 9070's 69th percentile ranking versus the W7100's 71st might suggest near parity in the overall database, but that is misleading—the RX 9070's average score of 23,877 is dragged down by its weak Passmark DirectX 9, 10, 11, and 12 results (343, 141, 281, and 74 respectively), which likely reflect driver overhead or benchmark quirks rather than real-world capability.

The W7100's only statistical advantage is its slightly higher percentile rank, but this is an artifact of its narrower benchmark suite. For any user choosing between these two, the RX 9070 is the obvious pick. Its launch MSRP is 549 USD, but the performance gap justifies the generational upgrade. The W7100 belongs in a museum or a legacy workstation that cannot accept modern cards.

Where Each One Wins

AMD Radeon RX 9070 wins in every compute and graphics workload measured. Its OpenCL score of 131,539 is 5.4x higher, its Vulkan score of 58,705 is 2.1x higher, and its FP32 throughput of 36.13 TFLOPS is over ten times the W7100's. The RX 9070 also dominates in memory-heavy tasks with 644.6 GB/s bandwidth versus 160.0 GB/s, making it the clear choice for large dataset processing, high-resolution textures, and modern gaming at 4K. The presence of ray tracing cores and DirectX 12 Ultimate support further cements its position for current and future titles. Its 322.6 GPixel/s pixel rate and 564.5 GTexel/s texture rate mean fill-rate-bound scenarios also favor the RX 9070 overwhelmingly.

AMD FirePro W7100 wins in the narrow niche of legacy compatibility and power efficiency. Its 150 W TDP is 70 W lower than the RX 9070's 220 W, and it requires only a single 6-pin power connector versus dual 8-pin. The W7100's single-slot design allows installation in space-constrained chassis where the RX 9070's dual-slot footprint will not fit. For systems limited to PCIe 3.0, the W7100's interface matches the bus without negotiation issues. Its four DisplayPort 1.2 outputs could serve older display configurations, though the RX 9070's DisplayPort 2.1a and HDMI 2.1b are objectively superior for modern monitors. The W7100's higher percentile ranking (71st versus 69th) is the only statistical category where it leads, but this reflects its limited benchmark pool rather than any actual performance advantage. In the database's own head-to-head tests, the W7100 wins zero tests; the RX 9070 wins two.
