AMD Radeon RX 9070 GRE vs NVIDIA CMP 30HX Comparison

The NVIDIA CMP 30HX and AMD Radeon RX 9070 GRE occupy different corners of the GPU landscape, and the data reflects that clearly. The CMP 30HX is an end-of-life mining part from 2021, while the RX 9070 GRE is an active, modern gaming card. The single shared benchmark — Geekbench OpenCL — shows a massive performance gap, but the full picture involves architecture, memory, and interface differences that matter for specific use cases.

Head-to-Head Benchmarks

The only directly comparable benchmark result in the data is Geekbench OpenCL, and it is not close. The AMD Radeon RX 9070 GRE scores 109,309 points, while the NVIDIA CMP 30HX scores 65,199 points. That is a 40.4% advantage for the AMD card, which also wins the sole head-to-head matchup recorded. In raw compute terms, the RX 9070 GRE delivers 34.28 TFLOPS of FP32 performance, versus the CMP 30HX's 5.027 TFLOPS — a nearly sevenfold difference in theoretical peak throughput.

Looking at broader benchmark standings, the CMP 30HX actually holds a higher percentile ranking at 89 versus the RX 9070 GRE's 87. This is counterintuitive given the OpenCL result, but it stems from the average benchmark score methodology. The CMP 30HX has an average score of 63,842 across its tests, while the RX 9070 GRE averages 57,367. The RX 9070 GRE's average is dragged down by its other benchmark result: a 3DMark Steel Nomad DX12 score of 5,424, which is a modern, demanding test that the older card does not run.

The nearest rival data reinforces the split. The CMP 30HX's closest competitors are all within 0.6% of its average score, including the AMD Radeon Pro WX 9100 at 64,212 and the AMD Radeon RX 9060 XT LP at 63,830. The RX 9070 GRE sits near the Intel Arc A580 (57,756, 0.7% higher) and the AMD Radeon RX 6950 XT (58,392, 1.8% higher). This suggests the CMP 30HX is well-tuned for its specific workload set, while the RX 9070 GRE's average is less representative of its peak capability in modern APIs.

The Verdict

The data points to a clear split: the AMD Radeon RX 9070 GRE is the superior compute and gaming card, while the NVIDIA CMP 30HX is a specialized legacy part. If your workload involves modern graphics APIs, the RX 9070 GRE's DirectX 12 Ultimate support, 48 RT cores, and 34.28 TFLOPS FP32 make it the only rational choice for gaming or current-generation workloads. The 40.4% OpenCL win and the 12 GB versus 6 GB memory capacity solidify this.

However, the CMP 30HX is not without merit in its niche. Its 89th percentile ranking versus the RX 9070 GRE's 87th indicates that, within its tested benchmark suite, it performs very consistently. It also has a lower TDP of 125 W versus 220 W, and requires only a single 8-pin power connector compared to the RX 9070 GRE's 2x 8-pin. For a system constrained by power delivery or physical space — the CMP 30HX is 229 mm long versus the RX 9070 GRE's unspecified dimensions — the older card might fit where the newer one cannot.

The RX 9070 GRE is the better purchase for anyone building a current system. The CMP 30HX is strictly for niche deployments where its mining-oriented design, PCIe 1.0 x4 interface, and lack of display outputs are acceptable trade-offs for its lower power draw.

Specification Differences

The two cards differ on nearly every specification that matters. The CMP 30HX uses a TU116 chip on the Turing architecture, built on 12 nm at TSMC. The RX 9070 GRE uses Navi 48 on RDNA 4.0, built on 4 nm also at TSMC. Transistor counts diverge sharply: 6,600 million for NVIDIA versus 53,900 million for AMD.

Clock speeds tell a story of efficiency: the CMP 30HX has a base clock of 1530 MHz and boost of 1785 MHz, while the RX 9070 GRE has a lower base of 1420 MHz but a much higher boost of 2790 MHz (with a game clock of 2220 MHz). Memory is faster on AMD: 2250 MHz (18 Gbps effective) versus 1750 MHz (14 Gbps effective).

The RX 9070 GRE has 3072 shading units, 192 TMUs, 96 ROPs, and 48 RT cores. The CMP 30HX has 1408 shading units, 88 TMUs, and 48 ROPs, with no RT cores listed. Pixel and texture rates reflect this: 267.8 GPixel/s and 535.7 GTexel/s for AMD versus 85.68 GPixel/s and 157.1 GTexel/s for NVIDIA.

Power and connectivity differ completely. The CMP 30HX is 125 W TDP with a 300 W suggested PSU and PCIe 1.0 x4 interface. The RX 9070 GRE is 220 W TDP with a 550 W suggested PSU and PCIe 5.0 x16 interface. The CMP 30HX has no display outputs; the RX 9070 GRE has 1x HDMI 2.1b and 3x DisplayPort 2.1a. The CMP 30HX is dual-slot with 1x 8-pin; the RX 9070 GRE is also dual-slot but needs 2x 8-pin.

Architecture Differences

The architectural gap is generational. The CMP 30HX is built on NVIDIA's Turing architecture, which is a 12 nm design with a transistor density of 23.2M per mm². It lacks dedicated RT cores and tensor cores in the data provided. Its FP16 performance is listed as 10.05 TFLOPS (2:1), meaning it halves FP32 throughput for FP16 workloads.

The RX 9070 GRE uses AMD's RDNA 4.0 architecture on a 4 nm process, achieving a transistor density of 151.0M per mm² — over six times denser than Turing. It includes 48 RT cores for hardware ray tracing. Critically, its FP16 performance matches FP32 at 34.28 TFLOPS (1:1), meaning no throughput penalty for half-precision compute.

Memory architecture also differs. Both use a 192-bit bus, but the RX 9070 GRE pairs it with 12 GB and 432.0 GB/s bandwidth, while the CMP 30HX has 6 GB and 336.0 GB/s. The RX 9070 GRE supports DirectX 12 Ultimate, which includes features like ray tracing and mesh shaders; the CMP 30HX is limited to DirectX 12 (12_1).

The RX 9070 GRE's predecessor is listed as "Navi III," and it is part of the "Navi IV (RX 9000)" generation. The CMP 30HX has no listed predecessor or successor, and it belongs to the "Mining GPUs" generation. Its PCIe 1.0 x4 interface is a notable bottleneck for data transfer, whereas the RX 9070 GRE uses PCIe 5.0 x16, offering vastly more bandwidth to the host system.

Where Each One Wins

The AMD Radeon RX 9070 GRE wins in every compute-heavy scenario. Its FP32 performance is 34.28 TFLOPS versus 5.027 TFLOPS, its memory bandwidth is 432.0 GB/s versus 336.0 GB/s, and it has 48 RT cores versus none. The 40.4% OpenCL benchmark win confirms this translates to real-world performance. It is the clear choice for gaming, 3D rendering, video editing, or any workload that leverages modern APIs like DirectX 12 Ultimate.

The NVIDIA CMP 30HX wins in niche scenarios unrelated to raw performance. Its 125 W TDP is nearly half the RX 9070 GRE's 220 W, making it easier to cool and power in constrained systems. It requires only a 300 W PSU versus 550 W, and a single 8-pin connector versus 2x 8-pin. Its 89th percentile ranking suggests it performs well in its tested workloads, likely compute tasks that do not require display output or modern graphics features.

The CMP 30HX also has a physical footprint advantage: 229 mm length, 111 mm height, and 35 mm width. While the RX 9070 GRE's dimensions are not listed, the CMP 30HX's compact size and lack of display outputs make it suited for mining rigs or headless compute servers where space and power efficiency are priorities. The RX 9070 GRE, with its display outputs and active production status, is designed for end-user systems that need a full-featured graphics card.
