NVIDIA CMP 50HX vs NVIDIA GeForce RTX 4070 Comparison

NVIDIA CMP 50HX and NVIDIA GeForce RTX 4070 occupy opposite ends of the GPU spectrum, one built for a single-purpose mining workload and the other for general consumer compute and graphics. The recorded data shows a clear generational and architectural divide, with the RTX 4070 dominating every shared benchmark while the CMP 50HX offers a higher transistor density and a wider memory bus. This analysis breaks down where each card wins, the architectural differences that explain the results, and what the numbers mean for potential users.

Where Each One Wins

The benchmark results are unambiguous: the RTX 4070 wins both recorded tests outright, with zero wins for the CMP 50HX across the shared benchmarks. In Geekbench OpenCL, the RTX 4070 scores 154858 against the CMP 50HX’s 56135, a delta of -63.8% from the older card’s perspective. In Geekbench Vulkan, the margin is even larger: 174152 versus 47445, a -72.8% delta. The CMP 50HX does not have a single head-to-head victory in the database.

While the CMP 50HX lacks any benchmark wins, its design intent was never general compute. The card has no display outputs, a PCIe 1.0 x4 bus interface, and a 250 W TDP, all pointing to a mining-specific role where raw memory bandwidth and hash throughput mattered, not API performance. The RTX 4070, by contrast, is a mainstream consumer card with HDMI 2.1 and DisplayPort 1.4a outputs, a PCIe 4.0 x16 interface, and a 200 W TDP. The data indicates that for any general-purpose workload, the RTX 4070 is the clear choice, while the CMP 50HX’s strengths are confined to its original, now obsolete mining context.

Architecture Differences

The two GPUs are separated by two full architecture generations. The CMP 50HX uses the TU102 chip on the Turing architecture, built on TSMC’s 12 nm process. The RTX 4070 uses the AD104 chip on the Ada Lovelace architecture, built on TSMC’s 5 nm process. This process shrink is dramatic: the RTX 4070 packs 35,800 million transistors on a 294 mm² die, yielding a transistor density of 121.8M per mm². The CMP 50HX has 18,600 million transistors spread across a much larger 754 mm² die, for a density of just 24.7M per mm². The Ada Lovelace design achieves nearly five times the transistor density, which directly contributes to its higher clock speeds and efficiency.

The core configurations tell a similar story. The RTX 4070 has 5888 shading units, 184 TMUs, and 64 ROPs. The CMP 50HX has 3584 shading units, 192 TMUs, and 80 ROPs. Despite having fewer shading units, the RTX 4070 reaches a much higher FP32 throughput of 29.15 TFLOPS, compared to the CMP 50HX’s 11.07 TFLOPS. The RTX 4070 also has a 1:1 FP16 ratio at the same 29.15 TFLOPS, while the CMP 50HX’s FP16 is listed as 22.15 TFLOPS with a 2:1 ratio, meaning it halves the FP32 rate when doing FP16.

Memory is a mixed bag. The CMP 50HX has 10 GB of GDDR6 on a 320-bit bus, delivering 560.0 GB/s of bandwidth. The RTX 4070 has 12 GB of GDDR6X on a 192-bit bus, but only 504.2 GB/s. The CMP 50HX’s wider bus gives it a bandwidth advantage, likely a deliberate choice for mining workloads that thrash memory heavily. The RTX 4070 compensates with faster effective memory speed (21 Gbps versus 14 Gbps) and more capacity. The CMP 50HX also has more RT cores (56 versus 46) and more tensor cores (448 versus 184), though these are Turing-generation units with much lower per-core performance than Ada Lovelace’s third-generation RT and fourth-generation tensor cores.

Clock speeds are another major divider. The CMP 50HX runs at a 1350 MHz base and 1545 MHz boost. The RTX 4070 runs at 1920 MHz base and 2475 MHz boost. This nearly 1.6x boost clock advantage, combined with the newer architecture, explains the large benchmark gaps. The RTX 4070 also has a higher pixel rate (158.4 GPixel/s versus 123.6 GPixel/s) and a much higher texture rate (455.4 GTexel/s versus 296.6 GTexel/s), despite having fewer TMUs.

Head-to-Head Benchmarks

The two shared tests present a stark picture. Geekbench OpenCL shows the RTX 4070 at 154858, which is 2.76 times the CMP 50HX’s 56135. The delta of -63.8% from the CMP 50HX’s perspective means the older card is performing at roughly 36% of the RTX 4070’s level. This is not a close race; it is a generational wipeout. The RTX 4070’s higher FP32 throughput, faster clocks, and more efficient architecture are all reflected in this score.

Geekbench Vulkan is even more lopsided. The RTX 4070 scores 174152, while the CMP 50HX manages 47445. That is a -72.8% delta, meaning the RTX 4070 delivers 3.67 times the Vulkan performance. The gap is larger in Vulkan than in OpenCL, suggesting the RTX 4070’s newer driver support and architectural features for modern API workloads are particularly beneficial. The CMP 50HX was never designed for gaming or compute APIs, and this test highlights that limitation.

The RTX 4070’s average benchmark score across all recorded tests is 37648, which places it in the 81st percentile of all GPUs. The CMP 50HX has an average score of 51790, which sits in the 86th percentile. This is an interesting anomaly: despite losing both head-to-head tests, the CMP 50HX has a higher average score because it only has two recorded benchmarks, both of which are relatively high compared to the RTX 4070’s ten recorded tests, which include several lower-scoring DirectX legacy tests. The RTX 4070’s Passmark DirectX 9 score of 320 and DirectX 10 score of 139 drag its average down, though its Passmark G3D score of 26927 and GPU Compute score of 14720 are strong. The CMP 50HX’s two Geekbench scores are both above 47000, so its average is inflated by the lack of legacy tests.

The nearest rivals for each card further contextualize the data. The CMP 50HX’s closest competitor is the AMD Radeon RX 6900 XT, with an average score of 50951 and a delta of 1.6%, meaning the CMP 50HX is only 1.6% ahead. The RTX 4070’s closest rival is the NVIDIA Tesla P4, with an average score of 37628 and a delta of 0.1%, a near-tie. The RTX 4070 is also within 1.3% of the RTX 4080 Mobile, which scores 38135. These rival comparisons show that while the CMP 50HX is competitive with high-end AMD cards from its era, the RTX 4070 sits in a different performance tier entirely.

The Verdict

The data is clear: for any workload that uses OpenCL or Vulkan, the RTX 4070 is vastly superior. Its 154858 OpenCL score and 174152 Vulkan score dwarf the CMP 50HX’s 56135 and 47445, respectively. The RTX 4070 also offers modern features like display outputs, a PCIe 4.0 x16 interface, and 12 GB of memory, making it a viable general-purpose GPU. The CMP 50HX, with no display outputs and a PCIe 1.0 x4 interface, is unusable for standard desktop tasks.

The CMP 50HX does have a niche advantage in memory bandwidth, 560.0 GB/s versus 504.2 GB/s, and a wider 320-bit bus versus 192-bit. For a hypothetical mining workload that is bandwidth-bound, the CMP 50HX might hold its own, but the card is end-of-life and was released in mid-2021. The RTX 4070, released in early 2023, is also end-of-life but has a successor in the GeForce 50 series. The RTX 4070’s launch MSRP was 599 USD, and it offers a far more balanced feature set.

Users who need a GPU for gaming, rendering, or compute should choose the RTX 4070 without hesitation. The benchmark delta is so large that no architectural quirk can close the gap. Users who specifically need a mining card with high memory bandwidth and no display outputs might consider the CMP 50HX, but its end-of-life status and lack of modern API performance make it a poor choice for anything else.
