AMD Radeon RX 7650 GRE vs NVIDIA Rubin GPU Comparison

Where Each One Wins

The recorded data presents an unusual comparison: the AMD Radeon RX 7650 GRE has two benchmark entries in the database, while the NVIDIA Rubin GPU has none. The RX 7650 GRE posts a 3DMark Steel Nomad DX12 score of 2336 and a Geekbench OpenCL score of 83109. The Rubin GPU shows no benchmark results, no average score, and no rival comparisons in the database. This means every measurable performance win belongs to the RX 7650 GRE, simply because it is the only part with recorded test data.

The RX 7650 GRE sits at the 83rd percentile among all GPUs in the database, with an average benchmark score of 42723. Its nearest rivals are all NVIDIA parts: the GeForce RTX 4070 SUPER at 43223 (1.2% higher), the Quadro M6000 24 GB at 43262 (1.2% higher), the GeForce RTX 5050 Mobile at 43268 (1.3% higher), and the Quadro M6000 at 43301 (1.3% higher). The RX 7650 GRE trails each of these by roughly one percentage point, placing it in a tight competitive cluster.

The Rubin GPU, by contrast, has a 50th percentile ranking, which reflects an average score of zero. Without any benchmarks recorded, the database cannot place it among rivals. Its use case appears entirely different: it is a server-class accelerator with no display outputs, no DirectX, OpenGL, or Vulkan support, and an SXM module form factor. The RX 7650 GRE is a client graphics card with display outputs and full graphics API support. The data indicates the two parts serve separate markets, not competing segments.

Architecture Differences

The architectural split between the two is stark. The RX 7650 GRE uses the Navi 33 chip on RDNA 3.0 architecture, codenamed Hotpink Bonefish, built on a 6 nm process at TSMC. It contains 13,300 million transistors on a 204 mm² die, giving a transistor density of 65.2 million per square millimeter. The Rubin GPU uses the GR100 chip on the Rubin architecture, built on a 3 nm process, also at TSMC. It packs 336,000 million transistors on a 1456 mm² die, with a density of 230.8 million per square millimeter. The Rubin GPU has roughly 25 times the transistor count and a die over seven times larger.

Clock behavior differs substantially. The RX 7650 GRE has a base clock of 1720 MHz, a boost clock of 2695 MHz, and a game clock of 2350 MHz. The Rubin GPU has a base clock of 700 MHz and a boost clock of 2267 MHz, with no game clock listed. Memory clocks also diverge: the RX 7650 GRE runs at 2250 MHz (18 Gbps effective), while the Rubin GPU runs at 2695 MHz (10.8 Gbps effective). The Rubin GPU's lower effective data rate reflects its HBM4 memory design, which prioritizes bandwidth over raw clock speed.

Memory configurations could hardly be more different. The RX 7650 GRE has 8 GB of GDDR6 on a 128-bit bus, delivering 288.0 GB/s of bandwidth. The Rubin GPU has 288 GB of HBM4 on a 16384-bit bus, delivering 22.1 TB/s, approximately 77 times the bandwidth. The RX 7650 GRE uses a PCIe 4.0 x8 interface; the Rubin GPU uses PCIe 6.0 x16.

Compute resources also scale dramatically. The RX 7650 GRE has 2048 shading units, 128 texture mapping units, 64 ROPs, and 32 ray tracing cores. The Rubin GPU has 28672 shading units, 896 TMUs, 24 ROPs, and 896 tensor cores. The RX 7650 GRE has no tensor cores listed; the Rubin GPU has no ray tracing cores listed. Pixel rates differ: the RX 7650 GRE reaches 172.5 GPixel/s, the Rubin GPU only 54.41 GPixel/s, reflecting the latter's low ROP count. Texture rates favor the Rubin GPU at 2,031.2 GTexel/s versus 345.0 GTexel/s.

FP32 throughput favors the Rubin GPU at 130.0 TFLOPS versus 22.08 TFLOPS. FP16 also favors the Rubin GPU at 260.0 TFLOPS (2:1 ratio) versus 22.08 TFLOPS (1:1 ratio) for the RX 7650 GRE. Power envelopes are equally divergent: the RX 7650 GRE has a TDP of 170 W with a suggested PSU of 450 W, while the Rubin GPU has a TDP of 2300 W with a suggested PSU of 2700 W.

The Verdict

The data shows two products with no meaningful overlap. The RX 7650 GRE is a client graphics card for gaming and general graphics workloads. It has display outputs (1x HDMI 2.1a, 3x DisplayPort 2.1), supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, and fits in a dual-slot form factor with a single 8-pin power connector. Its dimensions are 204 mm in length and 115 mm in height. It launched on February 6, 2025, with a launch MSRP of 279 USD. Its predecessor is Navi II and its successor is Navi IV.

The Rubin GPU is a server accelerator. It has no display outputs, no graphics API support, and uses an SXM Module form factor. It has no launch MSRP in the database. Its predecessor is Server Blackwell, and it has no successor listed. Its release date is December 31, 2025. The Rubin GPU targets compute workloads that require massive memory capacity (288 GB) and extreme bandwidth (22.1 TB/s), plus tensor core throughput for AI tasks.

The recorded benchmarks confirm the RX 7650 GRE is competitive among client GPUs, sitting within 1.3% of four NVIDIA rivals. The Rubin GPU has no benchmark scores, so no performance comparison can be made from the database. A user selecting a client graphics card would choose the RX 7650 GRE; a user selecting a server compute accelerator would choose the Rubin GPU. The two never compete directly.

Head-to-Head Benchmarks

There are no head-to-head benchmark entries in the database for these two GPUs. The RX 7650 GRE has two standalone benchmark scores, while the Rubin GPU has none. The only numerical comparison possible comes from the RX 7650 GRE's nearest rival data. Those rivals are all NVIDIA client or workstation parts, not the Rubin GPU.

The RX 7650 GRE's average benchmark score of 42723 places it 1.2% behind the RTX 4070 SUPER (43223) and the Quadro M6000 24 GB (43262), and 1.3% behind the RTX 5050 Mobile (43268) and the Quadro M6000 (43301). These deltas are small, within a range that suggests near-parity performance among the five parts. The RX 7650 GRE's percentile rank of 83 indicates it outperforms the majority of all GPUs in the database.

For the Rubin GPU, the absence of benchmark data means no wins or losses can be attributed. Its 50th percentile rank with an average score of zero is a placeholder, not a measurement of performance. The database records no rival comparisons for it, reinforcing that it does not currently slot into the client GPU hierarchy.

The largest numerical gap in any comparison is between the Rubin GPU's theoretical specifications and the RX 7650 GRE's measured results. The Rubin GPU shows 130.0 TFLOPS FP32 versus 22.08 TFLOPS, a 5.9x difference. Memory bandwidth shows a 76.7x difference (22.1 TB/s versus 288.0 GB/s). Transistor count shows a 25.3x difference (336,000 million versus 13,300 million). These figures indicate the Rubin GPU is designed for a different performance class entirely, but without benchmark scores, the database cannot confirm real-world scaling.
