AMD Radeon RX 7650 GRE vs NVIDIA RTX 4000 Ada Generation Comparison

Head-to-Head Benchmarks

The recorded head-to-head data contains only one shared benchmark result between the AMD Radeon RX 7650 GRE and the NVIDIA RTX 4000 Ada Generation. In the Geekbench OpenCL test, the NVIDIA RTX 4000 Ada Generation scores 146,593, while the AMD Radeon RX 7650 GRE scores 83,109. This represents a delta of -43.3% for the AMD card, meaning the NVIDIA card delivers roughly 76% higher raw compute throughput in this OpenCL workload. The win count in the head-to-head comparison stands at 1 for NVIDIA and 0 for AMD.

Looking beyond the direct comparison, the average benchmark scores in the database place the NVIDIA RTX 4000 Ada Generation at 135,218, while the AMD Radeon RX 7650 GRE averages 42,723. That is approximately 3.2 times higher average performance for the NVIDIA card across all recorded tests. The percentile rankings reinforce this gap: the NVIDIA card sits in the 95th percentile of all GPUs, while the AMD card sits in the 83rd percentile.

The nearest rivals for the AMD Radeon RX 7650 GRE include the NVIDIA GeForce RTX 4070 SUPER with an average score of 43,223 (a delta of -1.2%), the NVIDIA Quadro M6000 24 GB at 43,262 (-1.2%), the NVIDIA GeForce RTX 5050 Mobile at 43,268 (-1.3%), and the NVIDIA Quadro M6000 at 43,301 (-1.3%). These tight deltas indicate the RX 7650 GRE clusters with mid-range GPUs from previous generations. For the NVIDIA RTX 4000 Ada Generation, the nearest rivals are the NVIDIA A10M at 135,230 (delta of 0%), the AMD Radeon PRO W6800 at 135,396 (-0.1%), the AMD Radeon Pro W6800X Duo at 135,774 (-0.4%), and the AMD Radeon PRO V620 at 136,472 (-0.9%). The near-zero deltas suggest the RTX 4000 Ada Generation sits in a performance tier occupied by professional workstation cards.

The single head-to-head result shows a decisive NVIDIA victory, but the database also records additional AMD benchmarks. The AMD card scores 2,336 in 3DMark Steel Nomad DX12, a test not run on the NVIDIA card in this comparison. The NVIDIA card has a Geekbench Vulkan score of 123,842, which is not available for the AMD card. These non-overlapping tests prevent a fuller head-to-head picture, but the available data consistently points to the NVIDIA card occupying a higher performance class.

Architecture Differences

The two cards derive from fundamentally different architectures. The AMD Radeon RX 7650 GRE uses the Navi 33 chip built on RDNA 3.0 architecture, with the codename Hotpink Bonefish. It belongs to the Navi III generation within the Radeon RX 7000 series. The NVIDIA RTX 4000 Ada Generation uses the AD104 chip based on Ada Lovelace architecture, part of the GeForce 40-series generation, specifically the Workstation Ada line.

Manufacturing processes differ as well. The AMD chip is fabricated on a 6 nm process at TSMC, while the NVIDIA chip uses a 5 nm process, also at TSMC. The transistor counts reveal a substantial gap: the AMD chip contains 13,300 million transistors on a 204 mm² die, giving a transistor density of 65.2 million per square millimeter. The NVIDIA chip packs 35,800 million transistors onto a 294 mm² die, resulting in a density of 121.8 million per square millimeter. That is nearly double the transistor density and 2.7 times the total transistor count.

Core configurations diverge sharply. The AMD card has 2,048 shading units, 128 texture mapping units, and 64 raster operation pipelines. It includes 32 ray tracing cores but no tensor cores. The NVIDIA card carries 6,144 shading units, 192 texture mapping units, and 64 ROPs. It has 48 ray tracing cores and 192 tensor cores. The NVIDIA card therefore has three times the shading units, 1.5 times the TMUs, and six times the tensor cores. Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Clock speeds tell a different story. The AMD card has a base clock of 1720 MHz, a boost clock of 2695 MHz, and a game clock of 2350 MHz. The NVIDIA card runs at a 1500 MHz base and 2175 MHz boost, with no game clock listed. Despite lower clocks, the NVIDIA card achieves higher raw throughput due to its wider hardware configuration. Memory clocks are identical at 2250 MHz with 18 Gbps effective speed for both cards.

Where Each One Wins

The data shows the NVIDIA RTX 4000 Ada Generation wins the only shared benchmark by a wide margin. In Geekbench OpenCL, the NVIDIA card outperforms the AMD card by 43.3% relative to the AMD score. This suggests workloads that rely on general compute performance, such as OpenCL-accelerated applications, will favor the NVIDIA card.

The NVIDIA card also wins on memory capacity and bandwidth. It has 20 GB of GDDR6 memory on a 160-bit bus, delivering 360.0 GB/s of bandwidth. The AMD card has 8 GB of GDDR6 on a 128-bit bus, providing 288.0 GB/s. For large datasets or memory-intensive rendering tasks, the NVIDIA card has 2.5 times the capacity and 25% more bandwidth.

Compute throughput numbers favor NVIDIA as well. The NVIDIA card delivers 26.73 TFLOPS FP32 and 26.73 TFLOPS FP16 (1:1 ratio). The AMD card delivers 22.08 TFLOPS FP32 and 22.08 TFLOPS FP16 (also 1:1). Texture rate for NVIDIA is 417.6 GTexel/s versus 345.0 GTexel/s for AMD. Pixel rate, however, favors AMD at 172.5 GPixel/s versus 139.2 GPixel/s for NVIDIA, indicating the AMD card may handle certain rasterization-bound tasks more efficiently per clock.

The AMD card wins on physical dimensions. It measures 204 mm in length and 115 mm in height, while the NVIDIA card measures 245 mm in length and 112 mm in height. The AMD card is shorter by 41 mm, though slightly taller by 3 mm. The AMD card uses a dual-slot cooler while the NVIDIA card fits a single-slot design. Power requirements also differ: the AMD card has a TDP of 170 W and a suggested PSU of 450 W, while the NVIDIA card has a TDP of 130 W and a suggested PSU of 300 W. The NVIDIA card draws less power while delivering higher performance.

The Verdict

The recorded data indicates the NVIDIA RTX 4000 Ada Generation is the stronger performer across compute-heavy benchmarks. Its average benchmark score of 135,218 is more than three times the AMD card's 42,723. The NVIDIA card wins the only direct head-to-head test by 43.3% in Geekbench OpenCL. Its higher shading unit count, larger memory pool, and greater bandwidth make it suitable for workloads that demand extensive parallel processing or large working sets.

The AMD Radeon RX 7650 GRE delivers a different set of strengths. Its higher boost clock of 2695 MHz and superior pixel rate of 172.5 GPixel/s suggest it may handle certain rasterization tasks more efficiently. It also occupies less physical space at 204 mm in length, and its dual-slot cooler with a 170 W TDP may fit into systems where the NVIDIA card's 16-pin connector is not available. The AMD card launched at a launch MSRP of 279 USD, a figure absent for the NVIDIA card.

The data supports choosing the NVIDIA RTX 4000 Ada Generation for users who prioritize raw compute performance, ray tracing capability, tensor core acceleration, and memory capacity. The AMD card may appeal to users who need a compact card with DisplayPort 2.1 outputs, higher pixel throughput, or compatibility with 8-pin power connections. The NVIDIA card's 95th percentile ranking versus the AMD card's 83rd percentile confirms a clear performance hierarchy, with the NVIDIA card operating in a professional workstation tier as evidenced by its nearest rivals including the NVIDIA A10M and AMD Radeon PRO W6800.
