It also has higher fill rates, with a pixel rate of 172.5 GPixel/s versus 99.84 GPixel/s, and a texture rate of 345.0 GTexel/s versus 299.5 GTexel/s. Its FP32 compute rating is 22.08 TFLOPS versus 19.17 TFLOPS for the NVIDIA card. The AMD card also has slightly higher memory bandwidth at 288.0 GB/s versus 280.0 GB/s.

The AMD card is also smaller in terms of chip complexity, with a 204 mm² die versus 294 mm² for the NVIDIA chip, but that is a manufacturing detail rather than a user-facing advantage. The AMD card uses a PCIe 4.0 x8 interface, while the NVIDIA card uses PCIe 4.0 x16, which gives the NVIDIA card more bandwidth to the host system.

Specification Differences

The two cards differ across nearly every major specification category. The AMD Radeon RX 7650 GRE uses a 6 nm process node from TSMC, while the NVIDIA RTX 4000 SFF Ada Generation uses a 5 nm node, also from TSMC. Transistor counts diverge sharply: 13,300 million for AMD versus 35,800 million for NVIDIA. Die sizes are 204 mm² and 294 mm² respectively.

Clock speeds show the AMD card running much faster. Base clocks are 1720 MHz versus 720 MHz, and boost clocks are 2695 MHz versus 1560 MHz. The AMD card has a game clock of 2350 MHz, while the NVIDIA card has no game clock listed. Memory clocks also differ: the AMD card runs at 2250 MHz (18 Gbps effective), while the NVIDIA card runs at 1750 MHz (14 Gbps effective).

Memory configurations differ in capacity and bus width. The AMD card offers 8 GB on a 128-bit bus; the NVIDIA card offers 20 GB on a 160-bit bus. Despite the wider bus, the NVIDIA card's bandwidth is slightly lower at 280.0 GB/s versus 288.0 GB/s due to slower memory clocks.

Compute unit counts vary significantly. The AMD card has 2,048 shading units, 128 TMUs, and 64 ROPs. The NVIDIA card has 6,144 shading units, 192 TMUs, and 64 ROPs. RT core counts are 32 for AMD and 48 for NVIDIA. The NVIDIA card also has 192 tensor cores, while the AMD card has none listed.

The NVIDIA card has a TDP of 70 W, uses no power connectors, and requires a 250 W power supply. The AMD card is larger at 204 mm by 115 mm, while the NVIDIA card is smaller at 168 mm by 69 mm. Display outputs differ: the AMD card has one HDMI 2.1a and three DisplayPort 2.1 outputs, while the NVIDIA card has four mini-DisplayPort 1.4a outputs.

Architecture Differences

The architectural divide is fundamental. The AMD Radeon RX 7650 GRE is built on RDNA 3.0 architecture, using the Navi 33 chip with the codename Hotpink Bonefish. It belongs to the Navi III (RX 7000) generation and the Radeon RX 7000 series. Its predecessor is Navi II and its successor is Navi IV.

The NVIDIA RTX 4000 SFF Ada Generation is built on Ada Lovelace architecture, using the AD104 chip. It belongs to the Workstation Ada generation and the GeForce 40-series family. Its predecessor is Workstation Ampere and its successor is Blackwell PRO W.

The process nodes differ: AMD uses 6 nm TSMC, NVIDIA uses 5 nm TSMC. This contributes to a large difference in transistor density. The AMD chip packs 65.2 million transistors per mm², while the NVIDIA chip packs 121.8 million per mm². The NVIDIA chip is both larger and denser, resulting in nearly 2.7 times the transistor count.

The RT core implementations differ. The AMD card has 32 RT cores, while the NVIDIA card has 48 RT cores. The NVIDIA card also includes 192 tensor cores, which are absent from the AMD card's specifications. Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API coverage is identical.

The memory architecture differs in capacity and bus width, as noted. The NVIDIA card's 20 GB capacity is 2.5 times the AMD card's 8 GB. The NVIDIA card also uses a 160-bit bus versus 128-bit for AMD, though the AMD card compensates with faster memory clocks to achieve slightly higher bandwidth.

The release dates differ by nearly two years. The AMD card was released on 2025-02-06, while the NVIDIA card was released on 2023-03-20. Both are currently marked as Active in production status. The AMD card has a launch MSRP of 279 USD; the NVIDIA card has no launch MSRP listed in the database.

The Verdict

The data points to a clear performance hierarchy. The NVIDIA RTX 4000 SFF Ada Generation dominates in compute benchmarks, with a Geekbench OpenCL score of 124,812 versus 83,109 for the AMD Radeon RX 7650 GRE. Its average benchmark score of 117,088 is more than double the AMD card's 42,723, and its 95th percentile ranking versus 83rd percentile confirms the gap.

The NVIDIA card is the stronger choice for compute-heavy workstation tasks. Its 20 GB memory capacity is a substantial advantage for large datasets, and its 192 tensor cores provide dedicated hardware for AI and machine learning workloads that the AMD card lacks. Its 70 W TDP with no external power connectors makes it far easier to integrate into constrained systems, and its smaller physical footprint at 168 mm by 69 mm fits into tighter chassis.

The AMD card does hold advantages in specific areas. Its higher clock speeds (boost up to 2695 MHz versus 1560 MHz) and higher fill rates (172.5 GPixel/s and 345.0 GTexel/s versus 99.84 GPixel/s and 299.5 GTexel/s) indicate it may excel in rasterization-heavy scenarios where raw pixel throughput matters. Its FP32 rating of 22.08 TFLOPS exceeds the NVIDIA card's 19.17 TFLOPS, and its slightly higher memory bandwidth of 288.0 GB/s versus 280.0 GB/s narrows the memory throughput gap.

The AMD card also has a lower transistor count and smaller die, which typically correlates with lower manufacturing complexity. Its higher TDP of 170 W versus 70 W suggests it requires more power to achieve its performance, but it also operates at much higher clock speeds.

Users prioritizing compute performance, memory capacity, and power efficiency should select the NVIDIA RTX 4000 SFF Ada Generation. The benchmark data shows it is in a different performance class entirely. Users prioritizing raw rasterization fill rates and higher clock speeds, or those requiring the newer DisplayPort 2.1 outputs found on the AMD card, may find the Radeon RX 7650 GRE more suitable for their specific workloads. The recorded data does not include a DirectX 12 benchmark for the NVIDIA card, so gaming performance comparisons remain incomplete.
