The AMD Radeon RX 7650 GRE uses a Navi 33 chip on a 6 nm process, while the NVIDIA GB10 uses a GB20B chip on a 5 nm process. The RX 7650 GRE has a die size of 204 mm² with 13,300 million transistors, whereas the GB10 has a die size of 382 mm² with an unknown transistor count. The RX 7650 GRE has a transistor density of 65.2M per mm²; the GB10 has no listed density.

Memory configurations are also distinct. The RX 7650 GRE has 8 GB of GDDR6 memory on a 128-bit bus with 288.0 GB/s bandwidth. The GB10 has 128 GB of LPDDR5X memory on a 256-bit bus with 273.2 GB/s bandwidth. Clock speeds differ: the RX 7650 GRE runs at 1720 MHz base and 2695 MHz boost, with a 2350 MHz game clock and 2250 MHz memory clock (18 Gbps effective). The GB10 runs at 1665 MHz base and 2418 MHz boost, with a 1067 MHz memory clock (8.5 Gbps effective).

Compute unit counts vary significantly. The RX 7650 GRE has 2048 shading units, 128 TMUs, 64 ROPs, and 32 ray tracing cores, with no tensor cores. The GB10 has 6144 shading units, 384 TMUs, 48 ROPs, 48 ray tracing cores, and 384 tensor cores. Pixel and texture rates differ: the RX 7650 GRE delivers 172.5 GPixel/s and 345.0 GTexel/s, while the GB10 delivers 116.1 GPixel/s and 928.5 GTexel/s. FP32 and FP16 performance are both 22.08 TFLOPS for the RX 7650 GRE, and both 29.71 TFLOPS for the GB10.

Physical and interface differences are notable. The RX 7650 GRE is a dual-slot card with a 204 mm length, 115 mm height, and a single 8-pin power connector. The GB10 is an integrated graphics processor (IGP) with dimensions of 150 mm by 51 mm by 150 mm and no power connectors. The RX 7650 GRE uses PCIe 4.0 x8, while the GB10 uses PCIe 5.0 x16. Display outputs also differ: the RX 7650 GRE has 1x HDMI 2.1a and 3x DisplayPort 2.1, while the GB10 has only 1x HDMI.

Architecture Differences

The architectural split is fundamental. The AMD Radeon RX 7650 GRE is built on RDNA 3.0 architecture, codenamed Hotpink Bonefish, and belongs to the Navi III (RX 7000) generation. The NVIDIA GB10 uses Blackwell 2.0 architecture and belongs to the Server Blackwell (Bxx) generation. The RX 7650 GRE is fabricated by TSMC on a 6 nm node, while the GB10 is also TSMC but on a 5 nm node.

Core organization reflects different design philosophies. The RX 7650 GRE uses 2048 shading units, 128 texture mapping units, and 64 raster output units, with 32 dedicated ray tracing cores. The GB10 uses 6144 shading units, 384 texture mapping units, and just 48 raster output units, with 48 ray tracing cores and 384 tensor cores. The tensor core count is a major differentiator, as the GB10 includes hardware specifically for AI and machine learning workloads, while the RX 7650 GRE has none.

Memory architecture also differs. The RX 7650 GRE uses GDDR6 memory with a 128-bit bus, while the GB10 uses LPDDR5X memory with a 256-bit bus. Despite the wider bus, the GB10's bandwidth is slightly lower at 273.2 GB/s versus 288.0 GB/s for the RX 7650 GRE, due to lower effective memory clocks. The GB10 has 16 times the memory capacity, 128 GB versus 8 GB, which points to a server-oriented role.

API support is starkly different. The RX 7650 GRE supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The GB10 lists DirectX, OpenGL, and Vulkan all as N/A, indicating it is not designed for traditional graphics APIs. The RX 7650 GRE's predecessor is Navi II and its successor is Navi IV, while the GB10's predecessor is Server Hopper and its successor is Server Rubin.

Where Each One Wins

The NVIDIA GB10 wins decisively in raw compute performance. Its Geekbench OpenCL score of 120,137 is 30.8% higher than the RX 7650 GRE's 83,109, and its Geekbench Vulkan score of 114,648 further demonstrates strength in compute-oriented APIs. The GB10's 29.71 TFLOPS FP32 and FP16 performance, along with 384 tensor cores, make it the clear choice for workloads that leverage parallel processing, AI inference, or scientific computation. Its 128 GB of memory and 256-bit bus also suit large datasets, despite slightly lower bandwidth than the RX 7650 GRE.

The AMD Radeon RX 7650 GRE wins in the context of traditional graphics workloads and system integration. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, making it compatible with consumer games and graphics applications. The RX 7650 GRE has a higher pixel rate at 172.5 GPixel/s versus 116.1 GPixel/s for the GB10, which indicates faster rasterization throughput. Its 8 GB GDDR6 memory, while smaller, is paired with higher bandwidth at 288.0 GB/s, which can benefit texture-heavy scenes.

The RX 7650 GRE also wins on physical footprint and power integration for desktop use. It is a compact dual-slot card at 204 mm length with a standard 8-pin power connector and a 450 W suggested PSU. The GB10, as an IGP, requires no power connectors and only a 300 W PSU, but it offers no discrete expansion options. The RX 7650 GRE's 6 nm process and 13,300 million transistors on a 204 mm² die make it a conventional discrete GPU, whereas the GB10's 5 nm process and 382 mm² die with unknown transistor count reflect a server-class integrated design.

In summary, the GB10 wins for compute density, memory capacity, and AI-oriented features. The RX 7650 GRE wins for graphics API compatibility, rasterization speed, and as a standard discrete GPU for consumer systems. The 30.8% OpenCL delta is the defining benchmark result, but the two cards serve fundamentally different roles.
