Architecture Differences

The AMD Radeon RX 7650 GRE belongs to the Radeon RX 7000 series and uses the Navi 33 chip built on RDNA 3.0 architecture, with the codename "Hotpink Bonefish" and generation "Navi III (RX 7000)". The NVIDIA RTX PRO 4000 Blackwell uses the GB203 chip built on Blackwell 2.0 architecture, with generation "Blackwell PRO W (x000)". Both are fabricated by TSMC, but on different process nodes: the AMD card uses a 6 nm node, while the NVIDIA card uses a 5 nm node.

The compute configurations differ substantially. AMD implements 2048 shading units, 128 texture mapping units, 64 ROPs, and 32 ray tracing cores. NVIDIA implements 8960 shading units, 280 texture mapping units, 96 ROPs, 70 ray tracing cores, and 280 tensor cores. The AMD card has no tensor core count recorded in the database. The FP32 compute throughput is 22.08 TFLOPS for AMD and 36.83 TFLOPS for NVIDIA, with both cards delivering FP16 at a 1:1 ratio relative to FP32.

Memory architectures are fundamental points of divergence. AMD uses 8 GB of GDDR6 across a 128-bit bus, delivering 288.0 GB/s. NVIDIA uses 24 GB of GDDR7 across a 192-bit bus, delivering 672.0 GB/s. The pixel rate is 172.5 GPixel/s for AMD versus 197.3 GPixel/s for NVIDIA, and the texture rate is 345.0 GTexel/s versus 575.4 GTexel/s.

The bus interfaces differ as well. AMD uses PCIe 4.0 x8, while NVIDIA uses PCIe 5.0 x16. Display outputs are also different: AMD provides 1x HDMI 2.1a and 3x DisplayPort 2.1, while NVIDIA provides 4x DisplayPort 2.1b. Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Where Each One Wins

The recorded head-to-head benchmark data shows only one shared test, 3dmark_3dmark_steel_nomad_dx12, and the NVIDIA RTX PRO 4000 Blackwell wins that test with a 49.7% margin. The AMD card has zero wins in the head-to-head comparison, and the NVIDIA card has one win.

The average benchmark score tells a separate story. The AMD Radeon RX 7650 GRE has an average score of 42723, placing it in the 83rd percentile of all GPUs in the database. The NVIDIA RTX PRO 4000 Blackwell has an average score of 27135, placing it in the 72nd percentile. The AMD card's nearest rivals are the NVIDIA GeForce RTX 4070 SUPER (43223, delta -1.2%), the NVIDIA Quadro M6000 24 GB (43262, delta -1.2%), the NVIDIA GeForce RTX 5050 Mobile (43268, delta -1.3%), and the NVIDIA Quadro M6000 (43301, delta -1.3%). All four rivals score within 1.3% of the AMD card.

The NVIDIA card's nearest rivals are the AMD Radeon RX 6700 XT (27425, delta -1.1%), the NVIDIA GeForce RTX 4070 Mobile (27435, delta -1.1%), the NVIDIA GeForce RTX 3090 (27565, delta -1.6%), and the NVIDIA RTX A4000 (26683, delta 1.7%). This places the NVIDIA card in a lower overall performance tier by average score, despite its commanding lead in the one shared test.

The NVIDIA card also carries a broader benchmark profile in the database, with recorded scores across passmark_directx_10 (173), passmark_directx_11 (276), passmark_directx_12 (97), passmark_directx_9 (354), passmark_g2d (1265), passmark_g3d (28427), passmark_gpu_compute (14805), and geekbench_vulkan (194168). The AMD card has recorded scores in 3dmark_3dmark_steel_nomad_dx12 (2336) and geekbench_opencl (83109).

Specification Differences

NVIDIA measures 241 mm (9.5 inches) in length, 111 mm (4.4 inches) in height, and 20 mm (0.8 inches) in width. Bus interface is PCIe 4.0 x8 for AMD and PCIe 5.0 x16 for NVIDIA. The AMD card has a launch MSRP of 279 USD. No launch MSRP is recorded for the NVIDIA card. Production status for both is Active.

Head-to-Head Benchmarks

The only shared benchmark in the database is 3dmark_3dmark_steel_nomad_dx12. In that test, the NVIDIA RTX PRO 4000 Blackwell scores 4648, and the AMD Radeon RX 7650 GRE scores 2336. The delta is -49.7% for the AMD card, meaning it trails by roughly half in this DirectX 12 workload. This is the single largest differentiator in the direct comparison.

The average benchmark scores complicate the picture. The AMD card's average of 42723 is substantially higher than the NVIDIA card's average of 27135, a difference of 15588 points. The AMD card's nearest rival, the NVIDIA GeForce RTX 4070 SUPER, sits at 43223, just 1.2% above the AMD card. The NVIDIA card's nearest rival, the AMD Radeon RX 6700 XT, sits at 27425, just 1.1% above the NVIDIA card. This places the two products in different performance tiers by the database's aggregate metric, even though the single shared test favors NVIDIA heavily.

The NVIDIA card shows a wide spread across its passmark sub-tests. Its passmark_g3d score is 28427, while passmark_gpu_compute is 14805. The DirectX 9 score is 354, DirectX 11 is 276, DirectX 10 is 173, and DirectX 12 is 97. The passmark_g2d score is 1265. Its geekbench_vulkan score is 194168. The AMD card's geekbench_opencl score is 83109.

The percentile ranking reinforces the tier separation. AMD sits at the 83rd percentile of all GPUs, while NVIDIA sits at the 72nd percentile. The AMD card's average score of 42723 places it in the same vicinity as the RTX 4070 SUPER and Quadro M6000 24 GB, both of which score within 1.3%. The NVIDIA card's average score places it near the RX 6700 XT and RTX 4070 Mobile, both within 1.1%, and the RTX 3090 within 1.6%.

The compute specification gap is notable. NVIDIA's FP32 throughput of 36.83 TFLOPS is 66.8% higher than AMD's 22.08 TFLOPS. Texture rate favors NVIDIA at 575.4 GTexel/s versus 345.0 GTexel/s, a 66.8% advantage. Pixel rate favors NVIDIA by a smaller margin, 197.3 GPixel/s versus 172.5 GPixel/s, a 14.4% advantage. Memory bandwidth favors NVIDIA by a larger factor, 672.0 GB/s versus 288.0 GB/s, a 133.3% advantage.

The power envelope runs counter to the performance gap. NVIDIA delivers higher compute and memory throughput while drawing 140 W, compared to AMD's 170 W. The NVIDIA card also requires a lower suggested PSU at 300 W versus 450 W. The NVIDIA card achieves this in a single-slot form factor, while AMD uses a dual-slot design.

The transistor density difference is substantial: NVIDIA packs 120.6M transistors per mm² versus AMD's 65.2M per mm². This density, combined with the larger die, explains the large gap in raw compute resources. The AMD card compensates with higher clock speeds, running a 1720 MHz base and 2695 MHz boost versus NVIDIA's 1230 MHz base and 2055 MHz boost. The clock advantage does not overcome the resource advantage in the recorded tests.
