AMD Radeon RX 7650 GRE vs NVIDIA B200 SXM6 Comparison

AMD Radeon RX 7650 GRE vs NVIDIA B200 SXM6

Head-to-Head Benchmarks

The recorded data presents an unusual comparison, as the two products occupy entirely different segments of the GPU market. The AMD Radeon RX 7650 GRE has two benchmark entries in the database, while the NVIDIA B200 SXM6 has no recorded benchmark scores. The RX 7650 GRE scores 2336 points in 3dmark_3dmark_steel_nomad_dx12 and 83109 points in geekbench_opencl. Its average benchmark score is 42723, placing it in the 83rd percentile of all GPUs in the database.

The NVIDIA B200 SXM6, by contrast, has an average benchmark score of 0 and sits in the 50th percentile. This is not an indication of poor performance, but rather reflects the absence of recorded test data. The B200 SXM6 is a server accelerator designed for data center workloads, not for the consumer benchmark suite used to evaluate the Radeon card. The database shows zero wins for either product in head-to-head comparisons, which aligns with the lack of overlapping test results.

The RX 7650 GRE delivers 22.08 TFLOPS of FP32 performance and 22.08 TFLOPS of FP16 performance in a 1:1 ratio. The B200 SXM6 delivers 69.34 TFLOPS of FP32 and 69.34 TFLOPS of FP16, also in a 1:1 ratio. This gives the B200 SXM6 approximately 3.14 times the raw compute throughput of the RX 7650 GRE in both precision formats. The Radeon card achieves a pixel rate of 172.5 GPixel/s and a texture rate of 345.0 GTexel/s. The B200 SXM6 records a pixel rate of 43.92 GPixel/s and a texture rate of 1,083.4 GTexel/s. The NVIDIA part is roughly 3.14 times faster in texture fill rate, while the AMD part is approximately 3.93 times faster in pixel fill rate, a consequence of the B200 SXM6 having only 24 ROPs compared to 64 on the Radeon.

Where Each One Wins

The RX 7650 GRE wins in scenarios where pixel throughput and consumer API support matter. Its 172.5 GPixel/s pixel rate, 64 ROPs, and support for DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4 make it functional for gaming and graphics workloads. The card has 8 GB of GDDR6 memory on a 128-bit bus, delivering 288.0 GB/s of bandwidth. Its 2048 shading units, 128 TMUs, and 32 ray tracing cores are configured for real-time rendering tasks.

The B200 SXM6 wins in compute-heavy environments where memory capacity and bandwidth dominate. It carries 180 GB of HBM3e memory on an 8192-bit bus, producing 8.19 TB/s of bandwidth. That is approximately 28.4 times the memory bandwidth of the Radeon card. The B200 SXM6 also features 18944 shading units, 592 TMUs, and 592 tensor cores, which support AI and high-performance computing workloads. Its 69.34 TFLOPS FP32 and FP16 throughput positions it for scientific simulation and machine learning training, areas where the RX 7650 GRE's 22.08 TFLOPS cannot compete.

The Radeon card supports display outputs with 1x HDMI 2.1a and 3x DisplayPort 2.1, making it suitable for direct display connection. The B200 SXM6 has no display outputs, confirming its role as a compute accelerator rather than a graphics card. The RX 7650 GRE uses a dual-slot form factor with a 1x 8-pin power connector and a suggested PSU of 450 W. The B200 SXM6 is an SXM Module with a suggested PSU of 1400 W.

Architecture Differences

The two GPUs are built on different architectures and process nodes. The AMD Radeon RX 7650 GRE uses the Navi 33 chip with RDNA 3.0 architecture, codenamed Hotpink Bonefish, part of the Navi III (RX 7000) generation. It is fabricated on a 6 nm process at TSMC with 13,300 million transistors on a 204 mm² die, yielding a transistor density of 65.2M per mm². The NVIDIA B200 SXM6 uses the GB100 chip with Blackwell architecture, part of the Server Blackwell (Bxx) generation. It is fabricated on a 5 nm process at TSMC with 208,000 million transistors on a 1628 mm² die, yielding a transistor density of 127.8M per mm². The B200 SXM6 has roughly 15.6 times more transistors and a die area about 7.98 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. Its memory runs at 2250 MHz, 18 Gbps effective. The B200 SXM6 has a base clock of 120 MHz and a boost clock of 1830 MHz. Its memory runs at 2000 MHz, 8 Gbps effective. The low base clock on the B200 SXM6 reflects a power-conscious idle state for a 1000 W part, while the boost clock reaches 1830 MHz under load.

The bus interfaces also diverge. The Radeon card connects via PCIe 4.0 x8, while the B200 SXM6 uses PCIe 6.0 x16. The AMD card is 204 mm long and 115 mm high, while the B200 SXM6 has no recorded dimensions, consistent with its SXM Module form factor. The RX 7650 GRE was released on 2025-02-06, while the B200 SXM6 was released on 2024-10-31. The Radeon card belongs to the Radeon RX 7000 series and has a predecessor in Navi II and a successor in Navi IV. The B200 SXM6 has a predecessor in Server Hopper and a successor in Server Rubin.

The Verdict

The data indicates that these products serve different purposes and should be selected based on workload requirements. The RX 7650 GRE is positioned for graphics and gaming, with a launch MSRP of 279 USD. It delivers 22.08 TFLOPS FP32, 8 GB of GDDR6 memory, and full display output support. Its benchmark performance places it in the 83rd percentile, and its nearest rivals include the NVIDIA GeForce RTX 4070 SUPER with an average score of 43223 and a delta of -1.2%, the NVIDIA Quadro M6000 24 GB with 43262 and -1.2%, the NVIDIA GeForce RTX 5050 Mobile with 43268 and -1.3%, and the NVIDIA Quadro M6000 with 43301 and -1.3%. The RX 7650 GRE's average benchmark score of 42723 sits slightly below these rivals, within a range of -1.2% to -1.3% of each.

The B200 SXM6 is a server accelerator with a launch MSRP of 34999 USD. It provides 180 GB of HBM3e memory, 8.19 TB/s of bandwidth, 592 tensor cores, and 69.34 TFLOPS of FP32 compute. Its 1000 W TDP and lack of display outputs confirm its data center orientation. The absence of benchmark scores and nearest rivals in the database reflects its specialized nature, not a performance deficit.

For a user building a consumer workstation or gaming PC, the RX 7650 GRE is the practical choice due to its display outputs, API support, and established benchmark results. For a user deploying a server for AI training or high-performance computing, the B200 SXM6 offers the memory capacity, memory bandwidth, and compute density required for such tasks. The recorded data does not support a direct performance comparison, as the two products share no common benchmark results.
