The Verdict

The data shows two cards with completely different design goals. The AMD Radeon PRO W7400 is a low-power, single-slot professional card. It runs at 55 W, needs no auxiliary power connectors, and fits in a 168 mm length. It targets systems where space and power are constrained, and its four DisplayPort 2.1 outputs suit multi-display professional setups.

The AMD Radeon RX 9070 is a high-performance consumer card. It delivers roughly 4.6 times the FP32 throughput (36.13 TFLOPS versus 7.885 TFLOPS), has double the memory capacity (16 GB versus 8 GB), and nearly quadruples memory bandwidth (644.6 GB/s versus 172.8 GB/s). Its average benchmark score of 23877 places it at the 69th percentile of all GPUs, while the PRO W7400 sits at the 50th percentile with no recorded benchmark results.

The recorded data shows the RX 9070 is ahead of its nearest rivals by small margins: 0.6% above the NVIDIA GeForce GTX TITAN Z, 1.1% above the NVIDIA GeForce RTX 3080 Mobile, while trailing the AMD Radeon RX 6800S by 0.8% and the NVIDIA GeForce RTX 2080 SUPER by 1.2%. The PRO W7400 has no nearest rivals listed, indicating a distinct positioning.

For raw compute and gaming workloads, the RX 9070 is the clear choice based on every measurable specification. For a workstation requiring minimal power draw, single-slot footprint, and no external power connectors, the PRO W7400 fits that niche. The RX 9070 also carries a launch MSRP of 549 USD, while the PRO W7400 has no launch MSRP recorded.

Head-to-Head Benchmarks

The head-to-head benchmark table contains no entries, so direct comparisons must rely on the specification data and the RX 9070's recorded benchmark performance.

The largest gap lies in raw compute throughput. The RX 9070 delivers 36.13 TFLOPS FP32, which is 28.245 TFLOPS higher than the PRO W7400's 7.885 TFLOPS. That is a 358% advantage for the RX 9070. The same ratio applies to FP16, where both cards operate at 1:1 with their FP32 rates.

Pixel and texture throughput show similar disparities. The RX 9070 reaches 322.6 GPixel/s, versus 70.40 GPixel/s for the PRO W7400, a 252.2 GPixel/s difference. Texture rate favors the RX 9070 at 564.5 GTexel/s versus 123.2 GTexel/s.

Memory bandwidth presents a decisive split. The RX 9070's 644.6 GB/s is 471.8 GB/s higher than the PRO W7400's 172.8 GB/s. The RX 9070 also doubles the memory bus width (256-bit versus 128-bit) and doubles memory capacity (16 GB versus 8 GB).

Clock speeds reinforce the performance gap. The RX 9070 boosts to 2520 MHz, while the PRO W7400 boosts to 1100 MHz. The base clocks differ even more dramatically: 1330 MHz versus 330 MHz.

The RX 9070's recorded benchmark scores show its real-world position. Its Passmark G3D score of 25381 and Geekbench OpenCL score of 131539 indicate strong compute capability. The PRO W7400 has no benchmark results in the database, so its practical performance cannot be quantified from recorded data.

Specification Differences

The two cards differ across nearly every major specification field.

Process and die: The PRO W7400 uses a 6 nm process with a 204 mm² die and 13,300 million transistors. The RX 9070 uses a 4 nm process with a 357 mm² die and 53,900 million transistors. Transistor density is 65.2M per mm² for the PRO W7400 versus 151.0M per mm² for the RX 9070.

Memory: The PRO W7400 has 8 GB GDDR6 on a 128-bit bus with 172.8 GB/s bandwidth. The RX 9070 has 16 GB GDDR6 on a 256-bit bus with 644.6 GB/s bandwidth.

Compute units: The PRO W7400 has 1792 shading units, 112 TMUs, 64 ROPs, and 28 RT cores. The RX 9070 has 3584 shading units, 224 TMUs, 128 ROPs, and 56 RT cores. Each of these is exactly double in the RX 9070.

Clock speeds: The PRO W7400 runs at 330 MHz base and 1100 MHz boost. The RX 9070 runs at 1330 MHz base, 2070 MHz game, and 2520 MHz boost. Memory clocks are 1350 MHz (10.8 Gbps effective) versus 2518 MHz (20.1 Gbps effective).

Power and cooling: The PRO W7400 has a 55 W TDP, is single-slot, needs no power connectors, and suggests a 250 W PSU. The RX 9070 has a 220 W TDP, is dual-slot, needs two 8-pin connectors, and suggests a 550 W PSU.

Architecture Differences

The PRO W7400 uses the RDNA 3.0 architecture on the Navi 33 chip, codenamed Hotpink Bonefish. It belongs to the Radeon Pro Navi generation. The RX 9070 uses the RDNA 4.0 architecture on the Navi 48 chip, belonging to the Navi IV generation within the Radeon RX 9000 series.

The architectural jump from RDNA 3.0 to RDNA 4.0 coincides with a process node shrink from 6 nm to 4 nm at TSMC. This allows the RX 9070 to pack 53,900 million transistors versus 13,300 million, a 4.05x increase, on a die that is only 1.75x larger. The resulting transistor density of 151.0M per mm² versus 65.2M per mm² reflects the denser 4 nm process.

Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Neither has tensor cores listed. Both support FP16 at a 1:1 ratio with FP32, meaning no dedicated half-precision acceleration path beyond what the shader units provide.

The RX 9070 doubles every compute resource of the PRO W7400: shading units, TMUs, ROPs, and RT cores all scale by exactly a factor of two. This symmetrical doubling, combined with higher clocks and wider memory bus, explains the large throughput differences.

The RX 9070's predecessor is listed as Navi III, while the PRO W7400's predecessor is Radeon Pro Vega. Both cards remain in active production.

Where Each One Wins

The RX 9070 wins in raw compute performance. Its 36.13 TFLOPS FP32 is 4.6 times the PRO W7400's 7.885 TFLOPS. Every throughput metric confirms this: pixel rate, texture rate, and memory bandwidth all favor the RX 9070 by large margins. The 16 GB memory capacity and 644.6 GB/s bandwidth make it suitable for large datasets and high-resolution textures.

The RX 9070 wins in clock speed. Boost clocks of 2520 MHz versus 1100 MHz, and base clocks of 1330 MHz versus 330 MHz, indicate substantially higher sustained processing capability. The game clock of 2070 MHz provides a reference for typical gaming workloads.

The RX 9070 wins in benchmark standing. Its 69th percentile versus all GPUs, with an average benchmark score of 23877, places it in the upper mid-range. The PRO W7400 sits at the 50th percentile with no benchmark scores recorded.

The PRO W7400 wins in power efficiency. At 55 W TDP, it draws 165 W less than the RX 9070's 220 W. It requires no power connectors and a 250 W PSU, versus two 8-pin connectors and a 550 W PSU. This makes it suitable for systems with limited power delivery.

The PRO W7400 wins in physical footprint. Its single-slot design and 168 mm length allow installation in compact chassis. The RX 9070's dual-slot design and unrecorded dimensions indicate a larger physical presence.

The PRO W7400 wins in display flexibility. Four DisplayPort 2.1 outputs support multi-monitor professional configurations. The RX 9070's single HDMI 2.1b plus three DisplayPort 2.1a offers one fewer DisplayPort connection.

The PRO W7400 wins in power connector simplicity. The absence of external power connectors means it can run from slot power alone, simplifying installation in pre-built systems or workstations with limited PSU headroom.

The RX 9070 wins in memory capacity and bandwidth. For workloads that exceed 8 GB, the PRO W7400 will hit a hard limit. The RX 9070's 16 GB and 3.7x bandwidth advantage directly support larger working sets.
