NVIDIA CMP 40HX vs NVIDIA RTX 4500 Ada Generation Comparison

Head-to-Head Benchmarks

The benchmark data presents a decisive matchup. The NVIDIA RTX 4500 Ada Generation wins both recorded tests, and the margins are substantial. In Geekbench OpenCL, the RTX 4500 Ada scores 160,786 points against 93,395 for the CMP 40HX, a lead of 72.2%. The gap widens further in Geekbench Vulkan, where the RTX 4500 Ada posts 171,401 points versus 77,879 for the CMP 40HX, an advantage of 120.1%. These are not close contests; the RTX 4500 Ada more than doubles the CMP 40HX's Vulkan output.

The average benchmark score tells a similar story. The RTX 4500 Ada averages 166,094 across its recorded tests, while the CMP 40HX averages 85,637. That places the RTX 4500 Ada in the 97th percentile of all GPUs in the database, while the CMP 40HX sits in the 93rd percentile. Although both are high performers relative to the broader field, the absolute performance gap between them is significant.

Looking at the nearest rivals in the database provides context for each card's standing. The RTX 4500 Ada's closest competitor is the NVIDIA RTX A5500, which averages 165,217, a delta of only 0.5%. The AMD Radeon PRO W7800 is nearly identical at 164,894, just 0.7% behind. The AMD Radeon Pro W6900X actually scores slightly higher at 168,574, putting it 1.5% ahead of the RTX 4500 Ada. The NVIDIA A100 PCIe 40 GB trails at 162,504, a 2.2% deficit. This places the RTX 4500 Ada in a tightly contested cluster of high-end workstation cards.

For the CMP 40HX, its nearest rivals include the AMD Radeon PRO W7600 at 87,108, which is 1.7% ahead, and the NVIDIA Quadro GP100 at 87,445, which is 2.1% ahead. The CMP 40HX does beat the AMD Radeon PRO W6600 (81,995, a 4.4% advantage) and the AMD Radeon Pro Vega 64X (80,959, a 5.8% advantage). The CMP 40HX is therefore competitive with mid-range workstation cards, but it is clearly a tier below the RTX 4500 Ada.

The Verdict

The data points to a single conclusion: the NVIDIA RTX 4500 Ada Generation is the superior product in every measured benchmark. It wins both head-to-head tests, holds a higher average score, and ranks higher in the overall GPU percentile distribution. The CMP 40HX, by contrast, wins no recorded tests and offers roughly half the average performance.

The RTX 4500 Ada is the clear choice for anyone seeking maximum compute throughput in OpenCL and Vulkan workloads. Its 97th percentile ranking means it outperforms the vast majority of GPUs in the database. The CMP 40HX, despite its respectable 93rd percentile, is simply outclassed in this comparison. The recorded data shows no scenario where the CMP 40HX takes the lead.

One notable distinction: the CMP 40HX has a launch MSRP of 699 USD. The RTX 4500 Ada has no recorded launch MSRP in the database. No further pricing analysis is possible from the available facts.

Architecture Differences

The two cards come from entirely different generations and design philosophies. The RTX 4500 Ada Generation is built on the Ada Lovelace architecture with the AD103 chip, manufactured on a 5 nm process at TSMC. It packs 45,900 million transistors into a 379 mm² die, yielding a transistor density of 121.1M per mm². The CMP 40HX, in contrast, uses the older Turing architecture with the TU106 chip, fabricated on a 12 nm process, also at TSMC. It contains 10,800 million transistors spread across a larger 445 mm² die, resulting in a much lower density of 24.3M per mm².

Memory configurations differ significantly. The RTX 4500 Ada offers 24 GB of GDDR6 memory on a 192-bit bus, delivering 432.0 GB/s of bandwidth. The CMP 40HX has 8 GB of GDDR6 on a wider 256-bit bus, achieving 448.0 GB/s. Despite having a wider bus, the CMP 40HX's older memory technology provides only marginally higher bandwidth. The RTX 4500 Ada has a massive capacity advantage.

The compute cores reveal the generational leap. The RTX 4500 Ada features 7,680 shading units, 240 texture mapping units, and 80 raster output units. It also includes 60 ray tracing cores and 240 tensor cores. The CMP 40HX has 2,304 shading units, 144 TMUs, and 64 ROPs, along with 36 ray tracing cores and 288 tensor cores. The RTX 4500 Ada has more than three times the shading units and nearly double the TMUs.

Clock speeds also favor the newer card. The RTX 4500 Ada runs at a base clock of 2070 MHz and boosts to 2580 MHz. The CMP 40HX operates at 1470 MHz base and 1650 MHz boost. Memory clocks follow suit: the RTX 4500 Ada's memory runs at 2250 MHz (18 Gbps effective), while the CMP 40HX's memory is at 1750 MHz (14 Gbps effective).

The resulting throughput figures are stark. The RTX 4500 Ada delivers 39.63 TFLOPS of FP32 performance and the same 39.63 TFLOPS for FP16 at a 1:1 ratio. The CMP 40HX manages 7.603 TFLOPS FP32 and 15.21 TFLOPS FP16 at a 2:1 ratio. Pixel and texture rates follow the same pattern: 206.4 GPixel/s and 619.2 GTexel/s for the RTX 4500 Ada, versus 105.6 GPixel/s and 237.6 GTexel/s for the CMP 40HX.

Power and physical characteristics also differ. The RTX 4500 Ada has a TDP of 210 W with a suggested PSU of 550 W, and it requires no external power connectors. The CMP 40HX has a TDP of 185 W with a suggested PSU of 450 W, and it uses a single 8-pin connector. Both are dual-slot cards, but the CMP 40HX has a width of 35 mm (1.4 inches) while the RTX 4500 Ada's width is not recorded.

The CMP 40HX is a mining-specific product with no display outputs. The RTX 4500 Ada offers 4x DisplayPort 1.4a outputs. The CMP 40HX also uses a PCIe 1.0 x4 bus interface, a severe bottleneck compared to the RTX 4500 Ada's PCIe 4.0 x16 interface. The CMP 40HX is marked as end-of-life, while the RTX 4500 Ada remains active in production. The RTX 4500 Ada was released on 2023-08-08, while the CMP 40HX launched on 2021-02-24.

Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX 4500 Ada's predecessor is Workstation Ampere, and its successor is Blackwell PRO W. The CMP 40HX has no recorded predecessor or successor.

Where Each One Wins

The RTX 4500 Ada Generation wins every recorded benchmark category. In Geekbench OpenCL, it leads by 72.2%. In Geekbench Vulkan, it leads by 120.1%. The average benchmark score reinforces this dominance, with the RTX 4500 Ada outperforming the CMP 40HX by a wide margin. The RTX 4500 Ada also wins in every architectural specification that matters for compute workloads: shading units, TMUs, ROPs, ray tracing cores, clock speeds, memory capacity, and FP32 throughput.

The CMP 40HX has no recorded benchmark wins. Its only advantages in the raw specifications are a wider memory bus (256-bit versus 192-bit), slightly higher memory bandwidth (448.0 GB/s versus 432.0 GB/s), and more tensor cores (288 versus 240). It also has a lower TDP of 185 W compared to 210 W. These factors do not translate into superior benchmark results in the recorded data.

For use cases, the RTX 4500 Ada is the obvious choice for workstation tasks involving OpenCL acceleration, Vulkan rendering, or any compute-heavy workload. Its 24 GB memory capacity supports large datasets, and its display outputs enable direct visualization. The 97th percentile ranking confirms its position among the top GPUs in the database.

The CMP 40HX, given its mining-oriented design with no display outputs and a PCIe 1.0 x4 interface, is not suitable for conventional graphics work. Its narrower role is reflected in its lower benchmark scores. In this head-to-head, the RTX 4500 Ada is the definitive winner across all measured dimensions.
