AMD Radeon RX 9070 GRE vs NVIDIA CMP 50HX Comparison

# AMD Radeon RX 9070 GRE vs NVIDIA CMP 50HX

The AMD Radeon RX 9070 GRE and NVIDIA CMP 50HX represent two fundamentally different approaches to GPU design, separated by four years of architectural evolution and aimed at entirely distinct markets. The RX 9070 GRE is a modern gaming-focused graphics card built on RDNA 4.0, while the CMP 50HX is a mining-specific accelerator from NVIDIA’s Turing era with no display outputs whatsoever. The data shows a decisive performance gap in favor of the AMD card, but the comparison reveals more than just raw numbers — it highlights how process technology, feature sets, and market positioning shape what a GPU can actually do.

Head-to-Head Benchmarks

The only shared benchmark between these two cards is Geekbench OpenCL, and the results are lopsided. The AMD Radeon RX 9070 GRE scores 109,309 points, while the NVIDIA CMP 50HX manages just 56,135 points. That translates to a 94.7% delta in favor of the RX 9070 GRE — nearly double the compute performance in this general-purpose workload. This is not a marginal win; it is a generational stomping. The RX 9070 GRE’s FP32 throughput of 34.28 TFLOPS versus the CMP 50HX’s 11.07 TFLOPS explains much of the gap, as OpenCL heavily exercises raw shader compute.

The CMP 50HX does have a counterargument in FP16 workloads, where its 22.15 TFLOPS (2:1 ratio) actually exceeds its FP32 output, but the RX 9070 GRE matches its FP32 figure at 34.28 TFLOPS in FP16 as well. In every measurable compute scenario, the AMD card wins outright. The head-to-head data confirms this with a 1-0 win tally for the RX 9070 GRE.

Looking at broader benchmark context, the RX 9070 GRE’s average benchmark score of 57,367 places it in the 87th percentile of all GPUs, while the CMP 50HX’s 51,790 average sits at the 86th percentile. Interestingly, the RX 9070 GRE’s nearest rivals include the Intel Arc A580 (57,756, -0.7%), AMD Radeon RX 5600 OEM (58,085, -1.2%), and AMD Radeon RX 6950 XT (58,392, -1.8%) — all within 2% of its average score. The CMP 50HX, by contrast, sits slightly above the AMD Radeon RX 6900 XT (50,951, +1.6%), Radeon RX Vega 64 (50,001, +3.6%), and even the NVIDIA GeForce RTX 5070 Ti (49,957, +3.7%). The percentile rankings are close, but the RX 9070 GRE’s raw OpenCL advantage is overwhelming.

A: The RX 9070 GRE has 48 RT cores, while the CMP 50HX has 56 RT cores. However, the RX 9070 GRE’s RDNA 4.0 architecture is newer and its FP32 performance is roughly triple that of the CMP 50HX.

Q: What is the power consumption difference?

A: The RX 9070 GRE has a TDP of 220 W with a suggested 550 W PSU, while the CMP 50HX draws 250 W with a suggested 600 W PSU. The older 12 nm process node of the CMP 50HX contributes to its higher power draw despite lower performance.

Architecture Differences

The architectural chasm between these two GPUs is vast. The RX 9070 GRE uses AMD’s RDNA 4.0 architecture on a 4 nm TSMC process node, packing 53,900 million transistors into a 357 mm² die. This yields a transistor density of 151.0 million per square millimeter — an incredibly tight integration enabled by modern manufacturing. The CMP 50HX, by contrast, uses NVIDIA’s Turing architecture on a 12 nm TSMC node, with 18,600 million transistors spread across a massive 754 mm² die. Its transistor density is just 24.7 million per square millimeter, roughly one-sixth of the AMD chip’s density.

The clock speeds tell a similar story of generational progress. The RX 9070 GRE runs at a 1420 MHz base clock and boosts to 2790 MHz, with a game clock of 2220 MHz. The CMP 50HX operates at a 1350 MHz base and 1545 MHz boost — barely half the boost frequency of the AMD card. This clock advantage, combined with the architectural efficiency of RDNA 4.0, explains why the RX 9070 GRE achieves nearly triple the FP32 throughput despite having fewer shading units (3,072 vs 3,584).

Memory architecture also diverges significantly. The RX 9070 GRE uses a 192-bit bus with 12 GB of GDDR6 at 18 Gbps effective, delivering 432.0 GB/s. The CMP 50HX uses a wider 320-bit bus with 10 GB of GDDR6 at 14 Gbps, achieving 560.0 GB/s. The CMP 50HX’s higher bandwidth is notable for a mining card, where memory throughput often matters more than compute. However, the RX 9070 GRE compensates with much higher pixel rate (267.8 GPixel/s vs 123.6 GPixel/s) and texture rate (535.7 GTexel/s vs 296.6 GTexel/s).

The CMP 50HX includes 448 tensor cores alongside its 56 RT cores, reflecting Turing’s focus on AI acceleration and ray tracing. The RX 9070 GRE lists 48 RT cores but no tensor core count in the data. Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical despite the age difference.

Specification Differences

The specification sheets for these two cards differ in nearly every meaningful field. The RX 9070 GRE uses a 4 nm process and RDNA 4.0 architecture, while the CMP 50HX uses 12 nm and Turing. Transistor counts are 53,900 million versus 18,600 million, and die sizes are 357 mm² versus 754 mm². The RX 9070 GRE has a base clock of 1420 MHz and boost of 2790 MHz, compared to 1350 MHz and 1545 MHz for the CMP 50HX.

Memory configurations differ: 12 GB GDDR6 on a 192-bit bus with 432.0 GB/s bandwidth versus 10 GB GDDR6 on a 320-bit bus with 560.0 GB/s. Shading units favor the NVIDIA card at 3,584 versus 3,072, but TMUs are equal at 192, and ROPs favor AMD at 96 versus 80. The RX 9070 GRE has 48 RT cores; the CMP 50HX has 56 RT cores plus 448 tensor cores.

Pixel rate is 267.8 GPixel/s for AMD versus 123.6 GPixel/s for NVIDIA, and texture rates are 535.7 GTexel/s versus 296.6 GTexel/s. FP32 performance is 34.28 TFLOPS versus 11.07 TFLOPS, while FP16 is 34.28 TFLOPS (1:1) versus 22.15 TFLOPS (2:1). Power consumption is 220 W versus 250 W, with suggested PSUs of 550 W and 600 W respectively. Both are dual-slot with 2x 8-pin connectors.

The bus interface differs drastically: the RX 9070 GRE uses PCIe 5.0 x16, while the CMP 50HX is stuck with PCIe 1.0 x4 — a legacy interface that would bottleneck even modest data transfer. Display outputs are 1x HDMI 2.1b and 3x DisplayPort 2.1a on the AMD card, versus no outputs on the NVIDIA card. Dimensions also differ, with the CMP 50HX measuring 267 mm in length, 116 mm in height, and 35 mm in width, while the RX 9070 GRE has no listed dimensions.

Where Each One Wins

The AMD Radeon RX 9070 GRE wins in virtually every compute-oriented scenario. Its 94.7% OpenCL advantage makes it the clear choice for general-purpose GPU compute, content creation, and any workload that leverages FP32 or FP16 throughput. The 34.28 TFLOPS FP32 figure is nearly triple the CMP 50HX’s 11.07 TFLOPS, making the AMD card vastly superior for rendering, video encoding, and scientific computing tasks. Its active production status and modern feature set — including PCIe 5.0 and multiple display outputs — mean it can serve as a daily driver for gaming, productivity, and professional work alike. The 87th percentile ranking and 57,367 average benchmark score confirm it holds its own against contemporary rivals like the RX 6950 XT and Intel Arc A580.

The NVIDIA CMP 50HX wins in exactly one narrow category: memory bandwidth. Its 560.0 GB/s exceeds the RX 9070 GRE’s 432.0 GB/s, which could theoretically benefit bandwidth-bound workloads. Its 448 tensor cores also provide dedicated AI acceleration hardware that the AMD card lacks, potentially giving it an edge in machine learning inference tasks that can utilize Tensor Cores. However, these advantages are largely theoretical for a card with no display outputs and a PCIe 1.0 x4 interface — a severe bottleneck that would cripple data transfer in any modern system. The CMP 50HX’s 86th percentile ranking and 51,790 average score place it just slightly behind the RX 9070 GRE in overall performance, but its End-of-life status and mining-specific design limit its practical utility. For anyone building a system today, the RX 9070 GRE is the only rational choice — the CMP 50HX is a relic of a bygone mining era with few real-world applications beyond its original purpose.
