NVIDIA CMP 40HX vs NVIDIA RTX 6000 Ada Generation Comparison

Head-to-Head Benchmarks

The benchmark data shows a decisive performance gap between the NVIDIA RTX 6000 Ada Generation and the NVIDIA CMP 40HX. In the Geekbench OpenCL test, the RTX 6000 Ada Generation scores 311,629 points against 93,395 for the CMP 40HX. This represents a 233.7% advantage for the RTX 6000 Ada Generation, meaning it delivers more than three times the raw compute throughput in this workload.

The Vulkan results follow a similar pattern. The RTX 6000 Ada Generation records 262,845 points, while the CMP 40HX manages 77,879 points. The delta here is 237.5%, an even larger margin than the OpenCL test. Across both recorded benchmarks, the RTX 6000 Ada Generation wins all two head-to-head comparisons. The CMP 40HX does not win a single test.

Context from the nearest rivals underscores the significance of these numbers. The RTX 6000 Ada Generation sits at the 99th percentile among all GPUs in the database, with an average benchmark score of 287,237. Its closest rival, the NVIDIA L40, trails by just 1.1% with an average score of 284,111. The NVIDIA L40S is 2.9% ahead of the RTX 6000 Ada Generation with 295,763 points, and the AMD Instinct MI300X is 9.7% ahead with 317,994 points. The NVIDIA L20 sits 14.4% behind with 251,147 points. This places the RTX 6000 Ada Generation in a tightly contested band at the top of the performance hierarchy.

The CMP 40HX, by contrast, holds the 93rd percentile and an average benchmark score of 85,637. Its nearest rivals show a much tighter cluster: the AMD Radeon PRO W7600 is 1.7% ahead with 87,108 points, the NVIDIA Quadro GP100 is 2.1% ahead with 87,445 points, while the AMD Radeon PRO W6600 trails by 4.4% with 81,995 points, and the AMD Radeon Pro Vega 64X trails by 5.8% with 80,959 points. The CMP 40HX is competitive within its own performance tier, but that tier sits far below the RTX 6000 Ada Generation.

The raw specification data reinforces the benchmark results. The RTX 6000 Ada Generation delivers 91.06 TFLOPS of FP32 compute, while the CMP 40HX delivers 7.603 TFLOPS, a factor of roughly twelve. Texture rate stands at 1,422.8 GTexel/s for the RTX 6000 Ada Generation versus 237.6 GTexel/s for the CMP 40HX. Pixel rate is 481.0 GPixel/s against 105.6 GPixel/s. Memory bandwidth is 960.0 GB/s versus 448.0 GB/s. Every measurable throughput metric favors the RTX 6000 Ada Generation by a wide margin.

The Verdict

The data paints a clear picture. The RTX 6000 Ada Generation is in a different performance class entirely, with an average benchmark score more than three times that of the CMP 40HX. Its percentile ranking of 99 versus 93 reflects the spread: the RTX 6000 Ada Generation competes with the fastest accelerators in the database, while the CMP 40HX sits among mid-range workstation cards.

For workloads that stress OpenCL or Vulkan compute, the RTX 6000 Ada Generation is the only choice between these two. The 233.7% and 237.5% deltas in the two recorded tests are not marginal differences; they represent fundamentally different capability levels. The RTX 6000 Ada Generation also carries 48 GB of memory, six times the 8 GB on the CMP 40HX, which directly affects the size of datasets that can reside on the GPU.

The CMP 40HX, however, has its own niche. It draws 185 W of power, well below the 300 W of the RTX 6000 Ada Generation, and its dual-slot, 229 mm length makes it a smaller physical footprint. It uses a single 8-pin power connector and suggests a 450 W power supply, whereas the RTX 6000 Ada Generation uses a 16-pin connector and suggests 700 W. For systems with tighter power and space constraints, the CMP 40HX is the more modest option.

That said, the CMP 40HX has no display outputs, so it cannot drive a monitor directly. The RTX 6000 Ada Generation includes four DisplayPort 1.4a outputs. Anyone needing visual output from the GPU must choose the RTX 6000 Ada Generation.

From the recorded data alone, the RTX 6000 Ada Generation is the superior accelerator for compute-heavy tasks. The CMP 40HX is only suitable for scenarios where its lower power draw and compact size outweigh its substantial performance deficit.

Architecture Differences

The two cards come from different architectural generations. The RTX 6000 Ada Generation uses the AD102 chip built on the Ada Lovelace architecture, fabricated by TSMC on a 5 nm process. The CMP 40HX uses the TU106 chip from the Turing architecture, also fabricated by TSMC but on a 12 nm process. This process gap of 7 nm is a primary driver of the performance and efficiency differences.

Transistor counts reflect the scale of each design. The RTX 6000 Ada Generation packs 76,300 million transistors onto a 609 mm² die, yielding a transistor density of 125.3 million per square millimeter. The CMP 40HX has 10,800 million transistors on a 445 mm² die, for a density of 24.3 million per square millimeter. The RTX 6000 Ada Generation crams more than seven times the transistors into a die that is only about 37% larger in area.

The compute resources differ sharply. The RTX 6000 Ada Generation has 18,176 shading units, 568 texture mapping units, 192 raster operation units, 142 ray tracing cores, and 568 tensor cores. The CMP 40HX has 2,304 shading units, 144 TMUs, 64 ROPs, 36 ray tracing cores, and 288 tensor cores. The RTX 6000 Ada Generation has roughly eight times the shading units and nearly four times the ROP count.

Memory architecture also diverges. The RTX 6000 Ada Generation uses a 384-bit memory bus with 48 GB of GDDR6, while the CMP 40HX uses a 256-bit bus with 8 GB of GDDR6. Effective memory speed is 20 Gbps for the RTX 6000 Ada Generation versus 14 Gbps for the CMP 40HX, producing bandwidths of 960.0 GB/s and 448.0 GB/s respectively.

Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API coverage is identical. The RTX 6000 Ada Generation is part of the Workstation Ada generation and lists its predecessor as Workstation Ampere and its successor as Blackwell PRO W. The CMP 40HX belongs to the Mining GPUs generation and has no recorded predecessor or successor.
