AMD Radeon RX 7650 GRE vs NVIDIA CMP 50HX Comparison

Head-to-Head Benchmarks

The recorded data contains a single direct benchmark comparison between the NVIDIA CMP 50HX and the AMD Radeon RX 7650 GRE. In the Geekbench OpenCL test, the AMD Radeon RX 7650 GRE delivers a score of 83,109, while the NVIDIA CMP 50HX scores 56,135. This represents a 32.5% advantage for the AMD part, a decisive margin that dominates the head-to-head picture. The AMD GPU also holds a separate 3DMark Steel Nomad DX12 score of 2,336, though no corresponding result exists for the NVIDIA card in that test.

Context from the broader database places both cards in similar percentiles. The NVIDIA CMP 50HX sits at the 86th percentile across all GPUs, while the AMD Radeon RX 7650 GRE sits at the 83rd percentile. However, the average benchmark score tells a different story: the CMP 50HX averages 51,790 across its recorded tests, whereas the RX 7650 GRE averages 42,723. That gap, roughly 21%, favors the NVIDIA card in aggregate, even though the single direct comparison shows the AMD card winning by a wide margin. The explanation lies in the test mix: the CMP 50HX has two recorded Geekbench scores (OpenCL and Vulkan), while the RX 7650 GRE includes the 3DMark result, which is inherently more demanding and pulls its average down.

The nearest rivals for each card sharpen the analysis. The CMP 50HX sits just 1.6% above the AMD Radeon RX 6900 XT, 3.6% above the Radeon RX Vega 64, 3.7% above the GeForce RTX 5070 Ti, and 4.1% above the Intel Arc A550M. These are all modest deltas, indicating that the CMP 50HX competes in a tight cluster despite its mining-oriented design. The RX 7650 GRE, by contrast, trails its nearest rivals by small margins: it is 1.2% below the GeForce RTX 4070 SUPER, 1.2% below the Quadro M6000 24 GB, 1.3% below the RTX 5050 Mobile, and 1.3% below the Quadro M6000. The AMD card is effectively neck-and-neck with those parts, with no rival exceeding a 1.3% lead.

The takeaway from the head-to-head is unambiguous: in the one test where both cards ran the same workload, the RX 7650 GRE is far ahead. That result, however, does not erase the CMP 50HX's higher average score, which reflects its strong showing in Vulkan. The data suggests two different performance profiles rather than a simple hierarchy.

Architecture Differences

The two cards come from fundamentally different design philosophies. The NVIDIA CMP 50HX uses the TU102 chip, built on Turing architecture, fabricated on a 12 nm process at TSMC. The die measures 754 mm² and packs 18,600 million transistors, yielding a transistor density of 24.7 million per square millimeter. The AMD Radeon RX 7650 GRE uses the Navi 33 chip, built on RDNA 3.0 architecture, fabricated on a 6 nm process at TSMC. Its die is far smaller at 204 mm², with 13,300 million transistors, but the density is much higher at 65.2 million per square millimeter. The process node advantage is clear: 6 nm versus 12 nm allows AMD to pack more transistors per area, though the NVIDIA chip has more total transistors.

Compute resources diverge significantly. The CMP 50HX has 3,584 shading units, 192 texture mapping units, and 80 raster output pipelines. It also includes 56 RT cores and 448 tensor cores, reflecting Turing's focus on ray tracing and AI acceleration. The RX 7650 GRE has 2,048 shading units, 128 TMUs, and 64 ROPs, with 32 RT cores. The NVIDIA card leads in raw unit counts across the board. However, the AMD card compensates with much higher clocks: base 1720 MHz, boost 2695 MHz, and a game clock of 2350 MHz, versus the CMP 50HX's 1350 MHz base and 1545 MHz boost. That clock advantage drives the AMD card's higher pixel rate (172.5 GPixel/s versus 123.6 GPixel/s) and texture rate (345.0 GTexel/s versus 296.6 GTexel/s). In raw FP32 throughput, the RX 7650 GRE doubles the CMP 50HX: 22.08 TFLOPS versus 11.07 TFLOPS. FP16 output is similar, with the AMD card at 22.08 TFLOPS (1:1) and the NVIDIA card at 22.15 TFLOPS (2:1), meaning the NVIDIA figure relies on a packed rate.

Memory configurations are also distinct. The CMP 50HX offers 10 GB of GDDR6 on a 320-bit bus, delivering 560.0 GB/s of bandwidth. The RX 7650 GRE has 8 GB of GDDR6 on a 128-bit bus, delivering 288.0 GB/s. The NVIDIA card has a clear bandwidth advantage, but the AMD card has a higher memory clock (2250 MHz, 18 Gbps effective versus 1750 MHz, 14 Gbps effective). The bus interface differs as well: the CMP 50HX uses PCIe 1.0 x4, an unusual choice that limits modern connectivity, while the RX 7650 GRE uses PCIe 4.0 x8.

Feature sets reflect their intended roles. The CMP 50HX has no display outputs, as it was designed for mining. The RX 7650 GRE includes 1x HDMI 2.1a and 3x DisplayPort 2.1 outputs, making it a fully functional graphics card. Power requirements differ: the CMP 50HX draws 250 W with 2x 8-pin connectors and a suggested 600 W PSU, while the RX 7650 GRE draws 170 W with a single 8-pin connector and a suggested 450 W PSU. The AMD card is also smaller, at 204 mm length versus 267 mm, and has no recorded width, while the NVIDIA card is 35 mm thick.

The Verdict

The data points to a clear split in utility. The AMD Radeon RX 7650 GRE wins the only direct benchmark by 32.5%, offers double the FP32 throughput, consumes less power (170 W versus 250 W), and includes modern display outputs. It is also actively produced and has a launch MSRP of 279 USD. For any workload that requires a standard graphics card with rendering capability, the RX 7650 GRE is the better choice.

The NVIDIA CMP 50HX, however, holds advantages that matter in specific contexts. Its 10 GB memory on a 320-bit bus provides much higher bandwidth (560.0 GB/s versus 288.0 GB/s), and its average benchmark score is higher due to a strong Vulkan result. The 448 tensor cores and 56 RT cores give it AI and ray tracing capabilities that the AMD card lacks. But the lack of display outputs makes it unusable as a typical desktop GPU. The end-of-life status and 2021 release date further limit its appeal.

For a buyer evaluating both, the verdict depends entirely on use case. The RX 7650 GRE is the practical, modern choice with better compute performance. The CMP 50HX is a niche product for mining or compute tasks that prioritize memory bandwidth and tensor operations over raw FP32 throughput.

Where Each One Wins

AMD Radeon RX 7650 GRE wins on: raw compute throughput, as shown by its 22.08 TFLOPS FP32 versus 11.07 TFLOPS; the direct OpenCL benchmark with a 32.5% lead; power efficiency, with 170 W versus 250 W and a single 8-pin connector; pixel and texture rates, 172.5 GPixel/s and 345.0 GTexel/s respectively; modern connectivity via PCIe 4.0 x8 and display outputs; and active production status with a 2025 release.

NVIDIA CMP 50HX wins on: memory bandwidth, with 560.0 GB/s versus 288.0 GB/s on a wider 320-bit bus; memory capacity, with 10 GB versus 8 GB; tensor core availability, with 448 dedicated units; average benchmark score, at 51,790 versus 42,723; and overall GPU percentile ranking, at 86th versus 83rd.

The RX 7650 GRE is the card for general use, gaming, and standard compute workloads. The CMP 50HX is reserved for specialized tasks where bandwidth and tensor operations take precedence, though its lack of video outputs and mining-oriented design severely limit its everyday applicability.
