AMD Radeon RX 6950 XT vs AMD Radeon RX 7650 GRE Comparison

Where Each One Wins

The recorded benchmark data splits cleanly along workload type. The AMD Radeon RX 6950 XT wins both of the shared tests, but the margin is not uniform. In the DirectX 12 3DMark Steel Nomad test, the RX 6950 XT scores 4,235 against 2,336 for the RX 7650 GRE, a lead of 81.3%. That is a massive gap for a modern API workload, suggesting the older card’s larger memory subsystem and wider bus carry real weight in geometry-heavy scenes.

The second shared test, Geekbench OpenCL, shows an even larger delta. The RX 6950 XT posts 205,998 while the RX 7650 GRE manages 83,109, a 147.9% advantage. OpenCL is a compute-oriented benchmark, and here the RX 6950 XT’s 5,120 shading units versus 2,048 for the RX 7650 GRE explain the chasm. The RX 7650 GRE has no recorded win in any test, so its strengths must be inferred from architectural traits rather than direct scores.

The RX 7650 GRE does hold a higher boost clock (2,695 MHz versus 2,310 MHz) and a newer RDNA 3.0 architecture, but the data shows no benchmark where that translates into a victory. The RX 6950 XT also sits at the 88th percentile among all GPUs, while the RX 7650 GRE sits at the 83rd. That five-point percentile gap aligns with the raw score difference, though the RX 7650 GRE’s average score of 42,723 is still respectable for its class.

Architecture Differences

The two cards come from different generations and process nodes. The RX 6950 XT uses the Navi 21 chip on TSMC’s 7 nm process, with 26,800 million transistors on a 520 mm² die. The RX 7650 GRE uses Navi 33 on TSMC’s 6 nm process, with 13,300 million transistors on a 204 mm² die. The transistor density tells the story: the RX 7650 GRE packs 65.2 million transistors per mm² versus 51.5 million for the RX 6950 XT. That is a 27% density improvement, but the RX 6950 XT more than doubles the transistor count overall.

Memory configuration is a decisive differentiator. The RX 6950 XT carries 16 GB of GDDR6 on a 256-bit bus, yielding 576.0 GB/s of bandwidth. The RX 7650 GRE has 8 GB on a 128-bit bus, yielding 288.0 GB/s. That is exactly half the bandwidth, and half the memory capacity. For 4K textures or large compute buffers, this is a hard ceiling. The RX 7650 GRE’s memory clock is identical at 2250 MHz with 18 Gbps effective, so the bandwidth gap comes purely from the narrower bus.

Compute resources also diverge sharply. The RX 6950 XT has 5,120 shading units, 320 texture mapping units, and 128 render output units. The RX 7650 GRE has 2,048 shading units, 128 TMUs, and 64 ROPs. Ray tracing cores: 80 on the RX 6950 XT versus 32 on the RX 7650 GRE. Pixel rate is 295.7 GPixel/s versus 172.5 GPixel/s, and texture rate is 739.2 GTexel/s versus 345.0 GTexel/s. FP32 compute is closer: 23.65 TFLOPS for the RX 6950 XT versus 22.08 TFLOPS for the RX 7650 GRE, a mere 7% difference. FP16, however, shows the architectural split: the RX 6950 XT reaches 47.31 TFLOPS with a 2:1 ratio, while the RX 7650 GRE stays at 22.08 TFLOPS with a 1:1 ratio.

Power and physical design also differ. The RX 6950 XT has a 335 W TDP, requires a 700 W power supply, uses two 8-pin connectors, and occupies a triple-slot width. The RX 7650 GRE has a 170 W TDP, a 450 W suggested PSU, a single 8-pin connector, and a dual-slot design. The RX 6950 XT is 267 mm long, 120 mm tall, and 50 mm wide. The RX 7650 GRE is 204 mm long and 115 mm tall, with no recorded width. The RX 7650 GRE also supports DisplayPort 2.1 outputs, while the RX 6950 XT is limited to DisplayPort 1.4a.

Head-to-Head Benchmarks

The two shared tests paint a consistent picture, but the margins deserve scrutiny. In 3DMark Steel Nomad DX12, the RX 6950 XT’s 4,235 versus 2,336 represents an 81.3% advantage. This test stresses modern DirectX 12 features, and the RX 6950 XT’s 80 ray accelerators versus 32 likely contribute heavily. The RX 7650 GRE’s higher boost clock (2695 MHz versus 2310 MHz) cannot overcome the raw resource deficit.

Geekbench OpenCL shows an even wider gap: 205,998 versus 83,109, a 147.9% delta. OpenCL is a general-purpose compute API, and here the RX 6950 XT’s 5,120 shaders versus 2,048 shaders creates an algorithmic advantage that clock speed cannot bridge. The FP32 numbers are deceptively close (23.65 versus 22.08 TFLOPS), but real-world OpenCL workloads often scale with memory bandwidth and occupancy, both of which favor the RX 6950 XT substantially.

The RX 7650 GRE’s nearest rivals in the database are the NVIDIA GeForce RTX 4070 SUPER (average score 43,223, delta -1.2%), the NVIDIA Quadro M6000 24 GB (43,262, -1.2%), the NVIDIA GeForce RTX 5050 Mobile (43,268, -1.3%), and the NVIDIA Quadro M6000 (43,301, -1.3%). That places it in a tight cluster around 42,700 to 43,300. The RX 6950 XT, by contrast, sits among the NVIDIA P102-100 (58,528, -0.2%), Intel Arc A570M (58,239, +0.3%), AMD Radeon PRO V710 (58,657, -0.5%), and AMD Radeon RX 5600 OEM (58,085, +0.5%). The RX 6950 XT’s average score of 58,392 is 37% higher than the RX 7650 GRE’s 42,723, a gap that places them in entirely different performance tiers.

The Verdict

The data is unambiguous. The AMD Radeon RX 6950 XT is the stronger card in every recorded benchmark, and by a wide margin. For users who prioritize raw DirectX 12 and OpenCL performance, the RX 6950 XT delivers 81% to 148% more score depending on the workload. It also carries double the memory capacity and double the memory bandwidth, which matters for high-resolution textures and large datasets. The 88th percentile ranking versus the 83rd confirms the overall standing.

However, the RX 7650 GRE is not without rationale. Its 170 W TDP versus 335 W means significantly lower power draw, and its dual-slot, 204 mm length makes it far easier to fit in compact cases. The single 8-pin connector and 450 W PSU recommendation simplify installation. The DisplayPort 2.1 outputs provide future display connectivity that the RX 6950 XT lacks. For a user building a small form factor system or upgrading an older PSU, the RX 7650 GRE is the practical choice despite lower scores.

The RX 6950 XT was released on May 9, 2022, and is now end-of-life. The RX 7650 GRE launched on February 6, 2025, and remains active. That means the newer card offers ongoing driver support and likely better availability. But from a pure performance standpoint, the data says the RX 6950 XT is the superior product. The RX 7650 GRE’s higher boost clock and RDNA 3.0 architecture do not translate into any measured win.
