The Verdict

The data in the database is unambiguous regarding raw compute performance. The AMD Radeon PRO W7800 wins both recorded head-to-head benchmarks, with a 65.3% lead in OpenCL and a 125.2% lead in Vulkan. Its average benchmark score of 164,894 is nearly double the 85,637 of the NVIDIA CMP 40HX. For any workload that relies on general compute throughput, OpenCL acceleration, or Vulkan rendering, the AMD card is the clear choice based on the recorded measurements.

The NVIDIA CMP 40HX, however, is a different class of product. It is an end-of-life mining GPU with no display outputs, a PCIe 1.0 x4 bus interface, and a 185 W TDP. Its only advantage in the recorded data is its lower launch MSRP of 699 USD compared to 2,499 USD for the AMD card, but the benchmark results show a massive performance gap that far exceeds the price difference in relative terms.

Buyers should note the production status: the AMD card is active and supported, while the NVIDIA card is end-of-life. For professional compute tasks, rendering, or any workload requiring display output, the AMD Radeon PRO W7800 is the only viable option in this comparison. The NVIDIA CMP 40HX, with its lack of outputs and mining-specific design, has no use case in a standard workstation environment according to the recorded specifications.

Head-to-Head Benchmarks

The Geekbench OpenCL test shows the AMD Radeon PRO W7800 scoring 154,366 against 93,395 for the NVIDIA CMP 40HX. That is a delta of 65.3%, meaning the AMD card delivers roughly two-thirds more OpenCL throughput. This result aligns with the massive difference in shading units: 4,480 on the AMD card versus 2,304 on the NVIDIA card, and the FP32 throughput of 45.25 TFLOPS versus 7.603 TFLOPS.

The Geekbench Vulkan test shows an even wider gap. The AMD Radeon PRO W7800 scores 175,422, while the NVIDIA CMP 40HX scores 77,879. The delta here is 125.2%, meaning the AMD card is more than twice as fast in Vulkan. The AMD card's higher boost clock (2525 MHz versus 1650 MHz), larger memory pool, and greater texture and pixel rates all contribute to this outcome.

In the win/loss tally, the AMD Radeon PRO W7800 wins 2 benchmarks, and the NVIDIA CMP 40HX wins 0. The average benchmark score difference is 79,257 points in favor of the AMD part. Even when comparing the AMD card to its own nearest rivals, it sits within 0.2% of the NVIDIA RTX A5500 and 0.7% of the NVIDIA RTX 4500 Ada Generation, showing it is a competitive professional GPU. The NVIDIA CMP 40HX, by contrast, sits 1.7% behind the AMD Radeon PRO W7600 and 2.1% behind the NVIDIA Quadro GP100 in its nearest rival group.

Specification Differences

The most glaring difference is memory capacity: 32 GB on the AMD Radeon PRO W7800 versus 8 GB on the NVIDIA CMP 40HX. Both use GDDR6 and a 256-bit bus, but the AMD card's memory clock runs at 2250 MHz (18 Gbps effective) versus 1750 MHz (14 Gbps effective) on the NVIDIA part, yielding 576.0 GB/s versus 448.0 GB/s of bandwidth.

Compute resources differ substantially. The AMD card has 4,480 shading units, 280 texture mapping units, and 128 render output units. The NVIDIA card has 2,304 shading units, 144 TMUs, and 64 ROPs. Ray tracing cores number 70 on the AMD card versus 36 on the NVIDIA card. The NVIDIA card has 288 tensor cores, while the AMD card has none listed.

Clock speeds: the AMD card has a base clock of 1895 MHz and a boost clock of 2525 MHz. The NVIDIA card has a base clock of 1470 MHz and a boost of 1650 MHz. Pixel rate is 323.2 GPixel/s versus 105.6 GPixel/s, and texture rate is 707.0 GTexel/s versus 237.6 GTexel/s. FP32 throughput is 45.25 TFLOPS versus 7.603 TFLOPS. FP16 throughput is 90.50 TFLOPS versus 15.21 TFLOPS.

Power and physical specifications: the AMD card has a 260 W TDP, requires a 600 W suggested PSU, and uses 2x 8-pin power connectors. The NVIDIA card has a 185 W TDP, a 450 W suggested PSU, and a single 8-pin connector. The AMD card is 280 mm long, 110 mm tall, and 40 mm wide. The NVIDIA card is 229 mm long, 111 mm tall, and 35 mm wide. Both are dual-slot cards.

Bus interface and outputs: the AMD card uses PCIe 4.0 x16 and has 3x DisplayPort 2.1 plus 1x mini-DisplayPort 2.1. The NVIDIA card uses PCIe 1.0 x4 and has no display outputs.

Architecture Differences

The AMD Radeon PRO W7800 is built on the RDNA 3.0 architecture, codenamed Plum Bonito, using the Navi 31 chip. It is manufactured on a 5 nm process at TSMC. The chip contains 57,700 million transistors on a 529 mm² die, giving a transistor density of 109.1M per mm².

The NVIDIA CMP 40HX is built on the Turing architecture, using the TU106 chip. It is manufactured on a 12 nm process at TSMC. The chip contains 10,800 million transistors on a 445 mm² die, giving a transistor density of 24.3M per mm².

The process node difference is significant. The 5 nm node allows the AMD chip to pack over five times more transistors into a slightly larger die, and the density difference is stark: 109.1M per mm² versus 24.3M per mm². This explains the enormous gap in compute resources despite the similar board footprint.

The AMD card supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA card also lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API support is equivalent. The difference is in the hardware implementation: RDNA 3.0 with dedicated ray accelerators versus Turing with its ray tracing cores and tensor cores. The AMD card has no tensor cores listed, while the NVIDIA card has 288.

The AMD card's predecessor is the Radeon Pro Vega, and it is in the Radeon Pro Navi (Navi III Series) generation. The NVIDIA card has no predecessor listed and sits in the Mining GPUs generation. The NVIDIA card has no display outputs, which is a direct consequence of its mining-focused design, whereas the AMD card is a full professional workstation GPU with four display outputs.

Where Each One Wins

The AMD Radeon PRO W7800 wins in every recorded benchmark category. In OpenCL, it leads by 65.3%, and in Vulkan, it leads by 125.2%. The database also shows it holds a 97th percentile position among all GPUs, versus 93rd for the NVIDIA CMP 40HX. For compute-heavy tasks such as rendering, simulation, machine learning inference (via FP16 at 90.50 TFLOPS), or any workload that can leverage 32 GB of memory, the AMD card is the superior choice.

The AMD card's display outputs (3x DisplayPort 2.1 and 1x mini-DisplayPort 2.1) make it suitable for workstation use with multiple monitors. Its PCIe 4.0 x16 interface provides full bandwidth for data transfer, whereas the NVIDIA card is limited to PCIe 1.0 x4, which severely constrains data movement in and out of the GPU.

The NVIDIA CMP 40HX has no recorded benchmark wins. Its only practical advantages in the data are its lower TDP of 185 W versus 260 W, its smaller physical footprint (229 mm length versus 280 mm), and its lower launch MSRP of 699 USD. It also has 288 tensor cores, which the AMD card lacks, though no benchmark in the database specifically tests tensor core performance.

For a user who needs a mining GPU with no display output and low power draw, the NVIDIA CMP 40HX fits that narrow profile. For any professional or compute application that requires display output, high memory capacity, modern PCIe bandwidth, or maximum compute throughput, the AMD Radeon PRO W7800 is the only choice supported by the benchmark data. The 125.2% Vulkan lead and 65.3% OpenCL lead are decisive margins that no other specification in the pack can offset.
