Architecture Differences

The two cards come from completely different NVIDIA generations. The RTX 6000D is built on the Blackwell 2.0 architecture, using the GB202 chip fabricated on TSMC’s 5 nm process. The CMP 40HX is a Turing-generation part, using the TU106 chip on TSMC’s 12 nm process. This node gap alone explains much of the performance disparity. The RTX 6000D packs 92,200 million transistors into a 750 mm² die, giving a transistor density of 122.9M per mm². The CMP 40HX has 10,800 million transistors on a 445 mm² die, a density of 24.3M per mm². That is more than a fivefold density difference.

The shading and compute resources are also drastically different. The RTX 6000D has 19,968 shading units, 624 TMUs, and 192 ROPs. The CMP 40HX has 2,304 shading units, 144 TMUs, and 64 ROPs. Ray tracing and tensor hardware follow the same pattern: the RTX 6000D has 156 RT cores and 624 tensor cores, while the CMP 40HX has 36 RT cores and 288 tensor cores. The RTX 6000D’s FP32 throughput is 97.04 TFLOPS, and its FP16 throughput is identical at 97.04 TFLOPS with a 1:1 ratio. The CMP 40HX delivers 7.603 TFLOPS FP32 and 15.21 TFLOPS FP16 with a 2:1 ratio. The FP16 ratio difference indicates that the Turing card relies on a different execution path, while the Blackwell card handles both precision levels at the same rate.

Memory architecture is another major split. The RTX 6000D uses 84 GB of GDDR7 with a 448-bit bus and 1.40 TB/s of bandwidth. The CMP 40HX uses 8 GB of GDDR6 with a 256-bit bus and 448.0 GB/s. The bandwidth difference is roughly threefold in favor of the newer card. The CMP 40HX runs a PCIe 1.0 x4 interface, which is a severe bottleneck for any data transfer workload, while the RTX 6000D uses PCIe 5.0 x16. The CMP 40HX is also end-of-life, whereas the RTX 6000D is still active in production. The display output situation is telling: the RTX 6000D offers 4x DisplayPort 2.1b, while the CMP 40HX has no outputs, reflecting its mining-focused role.

Head-to-Head Benchmarks

The database contains one directly comparable benchmark between these two cards: Geekbench OpenCL. The RTX 6000D scored 388,405, and the CMP 40HX scored 93,395. That is a delta of 315.9% in favor of the RTX 6000D. To put that in perspective, the CMP 40HX would need to more than quadruple its score to match the RTX 6000D. The RTX 6000D’s average benchmark score across all recorded tests is 195,964, while the CMP 40HX’s average is 85,637. The gap is consistent with the OpenCL result, though the average gap is smaller because the RTX 6000D’s average includes its 3DMark Steel Nomad DX12 result of 3,522, which is a different workload type.

The nearest rival data reinforces the positioning. The RTX 6000D’s closest competitors include the NVIDIA Tesla V100S PCIe 32 GB at 194,415 (0.8% behind), the NVIDIA A100 SXM4 40 GB at 187,147 (4.7% behind), and the NVIDIA RTX 5000 Ada Generation at 184,664 (6.1% behind). The only rival that scores higher is the NVIDIA A100 PCIe 80 GB at 207,124, which is 5.4% ahead. This places the RTX 6000D in a very high-end compute tier. The CMP 40HX, by contrast, competes with the AMD Radeon PRO W7600 at 87,108 (1.7% behind), the NVIDIA Quadro GP100 at 87,445 (2.1% behind), the AMD Radeon PRO W6600 at 81,995 (4.4% ahead), and the AMD Radeon Pro Vega 64X at 80,959 (5.8% ahead). Its 93rd percentile rank shows it is still a capable card, but it is far from the top.

The 315.9% OpenCL delta is the single largest head-to-head margin in this comparison. No benchmark in the shared set favors the CMP 40HX. The wins tally is 1 for the RTX 6000D and 0 for the CMP 40HX.

The RTX 6000D lists its predecessor as Workstation Ada; the CMP 40HX has no predecessor or successor. The RTX 6000D’s launch MSRP is 8,565 USD, and the CMP 40HX’s launch MSRP is 699 USD.

Where Each One Wins

The RTX 6000D wins in every measured benchmark category that the database records for both cards. In Geekbench OpenCL, it is 315.9% ahead. Its average benchmark score of 195,964 is more than double the CMP 40HX’s 85,637. The RTX 6000D also wins on theoretical throughput, with 97.04 TFLOPS FP32 versus 7.603 TFLOPS, and on memory bandwidth, 1.40 TB/s versus 448.0 GB/s. For any workload that scales with raw compute, memory capacity, or memory bandwidth, the RTX 6000D is the clear choice. Its 84 GB of GDDR7 memory is suited for large model training, scientific simulation, or massive dataset processing. Its PCIe 5.0 x16 interface allows high-speed host communication, while the CMP 40HX’s PCIe 1.0 x4 interface would throttle even moderate data transfers.

The CMP 40HX’s wins are not in performance but in efficiency and footprint. It draws 185 W versus 600 W, requires only a 450 W suggested PSU versus 1000 W, and uses a single 8-pin connector instead of a 16-pin. Its physical dimensions are smaller: 229 mm versus 304 mm in length, 111 mm versus 137 mm in height, and 35 mm versus 40 mm in width. For environments where power delivery or physical space is constrained, the CMP 40HX is easier to integrate. Its launch MSRP of 699 USD is far below the RTX 6000D’s 8,565 USD, though that price gap is not a performance metric. The CMP 40HX also supports the same DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 API levels as the RTX 6000D, so software compatibility is not a differentiator.

The Verdict

The data is unambiguous: the RTX 6000D is the dominant performer. It wins the only head-to-head benchmark by 315.9%, holds an average benchmark score of 195,964 versus 85,637, and ranks in the 98th percentile of all GPUs versus the 93rd for the CMP 40HX. The RTX 6000D’s nearest rivals are data-center class accelerators like the A100 and V100S, which confirms its positioning as a high-end compute product. The CMP 40HX’s nearest rivals are midrange workstation cards like the Radeon PRO W7600 and Quadro GP100, which places it in a much lower performance tier.

Who should pick the RTX 6000D? Anyone whose workload demands massive memory capacity, extreme FP32 throughput, or high bandwidth. The 84 GB GDDR7 pool and 1.40 TB/s bandwidth are unique among the two cards, and the 156 RT cores and 624 tensor cores provide hardware acceleration for ray tracing and AI inference. The 600 W TDP and 1000 W suggested PSU mean it requires serious power infrastructure, but the performance return is proportional.

Who should pick the CMP 40HX? The card has no display outputs, so it is not for desktop use. It is end-of-life, so future driver optimization is unlikely. Its 185 W power draw and compact 229 mm length make it easier to deploy in dense or low-power environments, but its compute capabilities are roughly 12.8x lower in FP32 (7.603 TFLOPS versus 97.04 TFLOPS). The only scenario where the CMP 40HX makes sense is one where the workload is small enough to fit in 8 GB of GDDR6 memory and the power budget cannot accommodate 600 W. For any performance-sensitive task, the RTX 6000D is the only rational choice based on the recorded data.
