AMD Radeon RX 7650 GRE vs NVIDIA RTX PRO 4000 Blackwell SFF Comparison

Head-to-Head Benchmarks

The recorded database contains one direct head-to-head benchmark between these two cards: 3DMark Steel Nomad DX12. In this test, the NVIDIA RTX PRO 4000 Blackwell SFF delivers a score of 2910, while the AMD Radeon RX 7650 GRE posts 2336. The delta is 19.7% in favor of the NVIDIA card, which is a substantial margin in a single synthetic load. The RX 7650 GRE trails by roughly one-fifth of its own score, a gap that places it clearly behind in this specific rasterization-focused workload.

Looking at the broader benchmark landscape, the AMD card has a second recorded result: Geekbench OpenCL shows 83109 points. The NVIDIA card has no OpenCL entry in the database, so a direct comparison on that compute workload is not possible. The AMD card's average benchmark score across all recorded tests is 42723, while the NVIDIA card's average is 2910. These averages are not directly comparable because they are drawn from different test sets, but they do illustrate that the AMD card has multiple data points supporting its overall profile.

The nearest rival data adds context. The RX 7650 GRE sits at the 83rd percentile among all GPUs in the database. Its closest competitors, the NVIDIA GeForce RTX 4070 SUPER (average score 43223, delta -1.2%), the NVIDIA Quadro M6000 24 GB (43262, -1.2%), the NVIDIA GeForce RTX 5050 Mobile (43268, -1.3%), and the NVIDIA Quadro M6000 (43301, -1.3%) all hold a narrow edge over it. These deltas are small, within 1.3%, indicating the RX 7650 GRE is positioned in a tightly contested performance band.

The RTX PRO 4000 Blackwell SFF, by contrast, sits at the 19th percentile among all GPUs. Its nearest rivals are the NVIDIA GeForce RTX 4060 Ti 16 GB (average score 2907, delta 0.1%), the NVIDIA GeForce RTX 4060 Ti 8 GB (2913, -0.1%), the NVIDIA Quadro P600 (2923, -0.4%), and the NVIDIA GeForce RTX 4010 (2893, 0.6%). These deltas are all under 1%, meaning the RTX PRO 4000 Blackwell SFF clusters tightly with mid-range consumer cards in this benchmark. The 19th percentile ranking places it far below the RX 7650 GRE in overall database standing, despite winning the direct head-to-head test. This discrepancy reflects the fact that the percentile is computed across all recorded GPUs, and the RTX PRO 4000's single benchmark result does not capture the same breadth of workloads as the AMD card's two tests.

The direct comparison, however, is unambiguous. In 3DMark Steel Nomad DX12, the NVIDIA card wins the only shared test. The AMD card has no counter-victory in any recorded head-to-head benchmark, as the win tally shows 0 wins for the RX 7650 GRE and 1 win for the RTX PRO 4000 Blackwell SFF. For synthetic gaming-style DX12 rasterization, the data favors NVIDIA by a clear margin.

Architecture Differences

The two cards come from fundamentally different design lineages. The AMD Radeon RX 7650 GRE uses the Navi 33 chip built on RDNA 3.0 architecture, codenamed Hotpink Bonefish, and belongs to 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 65.2 million transistors per square millimeter. The NVIDIA RTX PRO 4000 Blackwell SFF uses the GB203 chip on Blackwell 2.0 architecture, from the Blackwell PRO W (x000) generation, on a 5 nm TSMC process. Its transistor count is 45,600 million across a 378 mm² die, for a density of 120.6 million per square millimeter. The NVIDIA chip packs more than three times the transistors into a die that is roughly 85% larger, and its density advantage is nearly double.

Memory configurations diverge sharply. The AMD card carries 8 GB of GDDR6 on a 128-bit bus, with 288.0 GB/s of bandwidth and memory clocked at 2250 MHz (18 Gbps effective). The NVIDIA card carries 24 GB of GDDR7 on a 192-bit bus, with 432.0 GB/s of bandwidth and memory at 1125 MHz (18 Gbps effective). The NVIDIA card offers triple the capacity and 50% more bandwidth. The GDDR7 type is a generational step over GDDR6, though both run at the same effective data rate.

Compute resources favor NVIDIA in raw counts. The RTX PRO 4000 Blackwell SFF has 8960 shading units, 280 texture mapping units, 96 render output units, 70 ray tracing cores, and 280 tensor cores. The RX 7650 GRE has 2048 shading units, 128 TMUs, 64 ROPs, and 32 ray tracing cores, with no tensor cores listed. NVIDIA's shading unit count is over four times higher, and its RT core count is more than double. The AMD card does counter with a higher pixel rate: 172.5 GPixel/s versus 128.8 GPixel/s, a 34% advantage. In texture rate, the NVIDIA card leads at 375.8 GTexel/s versus 345.0 GTexel/s, a 9% margin. FP32 compute is closer: NVIDIA posts 24.05 TFLOPS against AMD's 22.08 TFLOPS, a 9% lead. Both cards list FP16 at the same rate as FP32 (1:1).

Clock behavior is notably different. The AMD card runs a base clock of 1720 MHz, a boost of 2695 MHz, and a game clock of 2350 MHz. The NVIDIA card lists a base of 405 MHz and a boost of 1342 MHz, with no game clock. The AMD boost clock is more than double NVIDIA's boost, which explains how the AMD card achieves competitive pixel rates despite far fewer ROPs. The NVIDIA card compensates with a much wider execution footprint.

Power and physical characteristics differ substantially. The AMD card has a TDP of 170 W, requires a single 8-pin power connector, and a suggested PSU of 450 W. The NVIDIA card has a TDP of 70 W, no power connectors, and a suggested PSU of 250 W. The NVIDIA card draws less than half the power, a major efficiency distinction. Both are dual-slot cards. The AMD card measures 204 mm in length and 115 mm in height. The NVIDIA card is shorter at 167 mm, lower at 69 mm, and has a defined width of 40 mm. The bus interface also differs: AMD uses PCIe 4.0 x8, while NVIDIA uses PCIe 5.0 x8. Display outputs are 1x HDMI 2.1a plus 3x DisplayPort 2.1 on the AMD side, versus 4x mini-DisplayPort 2.1b on the NVIDIA side.

Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The AMD card's release date is 2025-02-06, while the NVIDIA card's is 2025-08-10. The AMD card's predecessor is Navi II and its successor is Navi IV. The NVIDIA card's predecessor is Workstation Ada, with no successor listed. The AMD card has a launch MSRP of 279 USD. The NVIDIA card has no launch MSRP recorded.

The Verdict

The data separates these two cards by role and workload. For a single synthetic DX12 rasterization test, the NVIDIA RTX PRO 4000 Blackwell SFF is the clear winner, delivering 19.7% higher performance. Its 24 GB of GDDR7 memory, 432.0 GB/s of bandwidth, and 70 RT cores make it a more capable platform for memory-intensive and ray-traced workloads. Its 70 W TDP with no power connectors and a 250 W suggested PSU also make it far easier to integrate into constrained systems, including small-form-factor builds.

The AMD Radeon RX 7650 GRE counters with a higher pixel rate (172.5 GPixel/s versus 128.8 GPixel/s), a much higher boost clock (2695 MHz versus 1342 MHz), and a smaller footprint in terms of transistor count and die size. It holds the 83rd percentile among all GPUs, far above the NVIDIA card's 19th percentile, though that gap is influenced by the different benchmark sets recorded for each card. The AMD card also has a launch MSRP of 279 USD, which is the only price data available in the database.

Users prioritizing raw performance in the recorded DX12 test should select the NVIDIA card. Users prioritizing overall database standing, higher pixel throughput, or lower physical length may favor the AMD card. The NVIDIA card is the better choice for compute-heavy tasks requiring large memory capacity and tensor cores. The AMD card is the better choice for rasterization throughput per clock and for systems with stricter power budgets, though the NVIDIA card actually draws less power. The data does not support a single universal winner; it supports a division by workload and system constraints.
