AMD Radeon RX 6750 GRE 12 GB vs NVIDIA CMP 50HX Comparison

The Verdict

The data splits these two cards cleanly by intent. The AMD Radeon RX 6750 GRE 12 GB is a conventional graphics card meant for gaming and general rendering, while the NVIDIA CMP 50HX is a mining-specific product with no display outputs. The benchmark results make the choice straightforward: the RX 6750 GRE wins the only head-to-head test (Geekbench Vulkan) by a massive 129.7% margin, scoring 108994 against 47445. It also holds a higher average benchmark score of 55698 versus 51790, and sits at the 87th percentile of all GPUs compared to the CMP 50HX's 86th. For anyone building a system that must output video, the CMP 50HX is disqualified outright — its "No outputs" specification means it cannot drive a monitor. The RX 6750 GRE is the only viable choice for interactive use, and the data supports it as the stronger performer in the shared test.

Architecture Differences

The two cards come from different process generations and design philosophies. The AMD Radeon RX 6750 GRE 12 GB uses the Navi 22 chip built on TSMC's 7 nm process, packing 17,200 million transistors into a 335 mm² die with a transistor density of 51.3M / mm². The NVIDIA CMP 50HX uses the TU102 chip on TSMC's 12 nm process, with 18,600 million transistors spread across a much larger 754 mm² die, yielding a lower density of 24.7M / mm². The AMD card runs the RDNA 2.0 architecture from the Navi II (RX 6000) generation, while the NVIDIA card uses the older Turing architecture from the "Mining GPUs" generation.

Memory configurations diverge significantly. The RX 6750 GRE has 12 GB of GDDR6 on a 192-bit bus, delivering 432.0 GB/s of bandwidth. The CMP 50HX has 10 GB of GDDR6 on a wider 320-bit bus, achieving 560.0 GB/s. Despite the narrower bus, the AMD card's higher memory clock (2250 MHz / 18 Gbps effective versus 1750 MHz / 14 Gbps effective) partially compensates, but the NVIDIA card retains the raw bandwidth advantage.

Compute resources tell a different story. The CMP 50HX has more shading units (3584 versus 2560), more TMUs (192 versus 160), more ROPs (80 versus 64), more RT cores (56 versus 40), and adds 448 tensor cores where the AMD card has none. Yet the RX 6750 GRE achieves higher clock speeds — base 2321 MHz versus 1350 MHz, boost 2581 MHz versus 1545 MHz — and those clocks push its FP32 throughput to 13.21 TFLOPS against the CMP 50HX's 11.07 TFLOPS. The AMD card also leads in pixel rate (165.2 GPixel/s versus 123.6 GPixel/s) and texture rate (413.0 GTexel/s versus 296.6 GTexel/s).

The cards also differ in connectivity and physical design. The RX 6750 GRE uses PCIe 4.0 x16, has display outputs (1x HDMI 2.1 and 3x DisplayPort 1.4a), and draws power from a 1x 6-pin + 1x 8-pin connector. The CMP 50HX uses a severely limited PCIe 1.0 x4 interface, has no display outputs, and requires 2x 8-pin connectors. Both are dual-slot cards with a 250 W TDP and a suggested 600 W PSU, but the AMD card is shorter in height (110 mm versus 116 mm) and thicker (40 mm versus 35 mm).

Where Each One Wins

The RX 6750 GRE wins every measurable comparison relevant to general use. It dominates the Geekbench Vulkan test with a score of 108994, which is 129.7% higher than the CMP 50HX's 47445. Its average benchmark score of 55698 places it just 0.1% behind the AMD Radeon 8060S and 0.7% behind the NVIDIA GeForce RTX 5080, while the CMP 50HX's 51790 average sits 1.6% ahead of the AMD Radeon RX 6900 XT and 3.6% ahead of the AMD Radeon RX Vega 64. In terms of percentile ranking, the AMD card reaches the 87th percentile of all GPUs, one point above the CMP 50HX's 86th.

The CMP 50HX's only clear advantages are architectural. It has more raw compute units, tensor cores, and higher memory bandwidth. Its 560.0 GB/s bandwidth is 29.6% higher than the RX 6750 GRE's 432.0 GB/s. It also has 448 tensor cores, which the AMD card lacks entirely. These features could theoretically benefit compute workloads that use tensor operations or require high memory throughput, but the card's lack of display outputs and PCIe 1.0 x4 interface severely limit its practical deployment. The NVIDIA card is also end-of-life, while the AMD card remains in active production.

FAQ

Q: Which card has the higher average benchmark score?

A: The AMD Radeon RX 6750 GRE 12 GB scores 55698 on average, compared to 51790 for the NVIDIA CMP 50HX — a difference of about 7.5%.

Q: Can the NVIDIA CMP 50HX be used for gaming on a monitor?

A: No. The CMP 50HX has "No outputs" listed in its display outputs specification, meaning it cannot connect to a display at all.

A: The RX 6750 GRE scores 108994 in Geekbench Vulkan versus 47445 for the CMP 50HX, a 129.7% advantage for the AMD card.

Q: Which card has more memory bandwidth?

A: The NVIDIA CMP 50HX has 560.0 GB/s of bandwidth on a 320-bit bus, while the AMD RX 6750 GRE has 432.0 GB/s on a 192-bit bus.

Q: What is the production status of each card?

A: The AMD RX 6750 GRE is listed as "Active" production, while the NVIDIA CMP 50HX is "End-of-life."

Q: Do both cards support the same APIs?

A: Yes, both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Head-to-Head Benchmarks

The only direct benchmark comparison available is Geekbench Vulkan, and the result is emphatic. The AMD Radeon RX 6750 GRE 12 GB scores 108994, while the NVIDIA CMP 50HX scores 47445. The delta is 129.7%, meaning the AMD card more than doubles the NVIDIA card's performance in this test. This single result aligns with the broader average benchmark scores, where the AMD card leads by 3908 points (55698 versus 51790).

The average score comparison also places each card in a different competitive tier. The RX 6750 GRE's 55698 average puts it within 0.7% of the NVIDIA GeForce RTX 5080 (56083) and 2.7% above the NVIDIA GeForce RTX 4080 (54247). It sits just 0.1% below the AMD Radeon 8060S and 1.6% above the AMD Radeon Pro W5700X. The CMP 50HX's 51790 average places it 1.6% above the AMD Radeon RX 6900 XT (50951) and 4.1% above the Intel Arc A550M (49737), but it trails the RX 6750 GRE by a wider margin than any of its nearest rivals.

The wins tally confirms the direction: the AMD card scores 1 win in head-to-head benchmarks, the NVIDIA card has 0. The RX 6750 GRE's victory in the Vulkan test is not close, and given that the CMP 50HX lacks display outputs, there is no practical scenario where the NVIDIA card's architectural advantages — tensor cores, higher bandwidth — translate into a user-facing win. The data consistently points to the AMD Radeon RX 6750 GRE 12 GB as the superior product for any workload that requires rendering to a screen.
