AMD Radeon RX 7650 GRE vs NVIDIA RTX 4500 Ada Generation Comparison

AMD Radeon RX 7650 GRE and NVIDIA RTX 4500 Ada Generation occupy very different segments of the GPU market, and the benchmark data confirms a wide performance gap. The recorded measurements place the RTX 4500 Ada Generation in the 97th percentile of all GPUs, while the RX 7650 GRE sits in the 83rd percentile. The average benchmark score for the NVIDIA card is 166,094, compared to 42,723 for the AMD card, a difference of roughly 3.9 times. These are not competing products in the same class; the data shows a clear stratification based on compute capacity and memory resources.

Head-to-Head Benchmarks

The only direct head-to-head benchmark recorded in the database is Geekbench OpenCL. In this test, the NVIDIA RTX 4500 Ada Generation scored 160,786, while the AMD Radeon RX 7650 GRE scored 83,109. The delta is -48.3 percent from the AMD card's perspective, meaning the RX 7650 GRE delivers less than half the OpenCL score of the RTX 4500 Ada Generation. This is a decisive win for the NVIDIA card, and the margin is substantial enough to indicate a different performance tier entirely.

Looking at the nearest rivals in the database provides additional context for both cards. The RX 7650 GRE has an average benchmark score of 42,723, which places it within 1.3 percent of cards like the NVIDIA GeForce RTX 4070 SUPER (43,223), the Quadro M6000 24 GB (43,262), and the GeForce RTX 5050 Mobile (43,268). The AMD card trails these by margins between 1.2 and 1.3 percent. This clustering suggests the RX 7650 GRE is competitive with those specific GPUs in aggregate database scoring, even though it loses decisively to the RTX 4500 Ada Generation in the OpenCL test.

The RTX 4500 Ada Generation, with its average score of 166,094, sits among workstation-class cards. Its nearest rivals include the NVIDIA RTX A5500 (165,217), which it beats by 0.5 percent, and the AMD Radeon PRO W7800 (164,894), which it beats by 0.7 percent. The NVIDIA A100 PCIe 40 GB (162,504) trails it by 2.2 percent. These delta values show the RTX 4500 Ada Generation holding a narrow but consistent lead over its closest measured competitors, a very different competitive picture from the RX 7650 GRE's tight grouping near the RTX 4070 SUPER.

The Geekbench Vulkan score for the RTX 4500 Ada Generation is 171,401, which is higher than its OpenCL score of 160,786. The RX 7650 GRE has no recorded Vulkan benchmark in the database, so cross-API comparison is limited to OpenCL. The data available indicates that the NVIDIA card maintains high performance across multiple compute APIs, while the AMD card's recorded results are confined to OpenCL and one 3DMark Steel Nomad DX12 test where it scored 2,336.

Architecture Differences

The two GPUs are built on different architectures from different generations. The AMD Radeon RX 7650 GRE uses the Navi 33 chip based on RDNA 3.0 architecture, with the codename Hotpink Bonefish. It belongs to the Navi III (RX 7000) generation. The NVIDIA RTX 4500 Ada Generation uses the AD103 chip based on Ada Lovelace architecture, and it belongs to the Workstation Ada generation.

The manufacturing process differs as well. The AMD card is fabricated on a 6 nm process at TSMC, while the NVIDIA card uses a 5 nm process, also at TSMC. The transistor counts reflect the scale difference between the two chips. The Navi 33 die contains 13,300 million transistors on a 204 mm² die, for a transistor density of 65.2 million per mm². The AD103 die contains 45,900 million transistors on a 379 mm² die, for a density of 121.1 million per mm². The NVIDIA chip has more than three times the transistor count and roughly 1.86 times the die area, with nearly double the transistor density.

Memory architecture differs significantly. The RX 7650 GRE has 8 GB of GDDR6 memory on a 128-bit bus, yielding 288.0 GB/s of bandwidth. The RTX 4500 Ada Generation has 24 GB of GDDR6 memory on a 192-bit bus, yielding 432.0 GB/s of bandwidth. The NVIDIA card offers three times the memory capacity and 1.5 times the bandwidth. Both cards run their memory at an effective 18 Gbps, so the bandwidth difference comes entirely from the wider bus.

Compute resources also diverge sharply. The RX 7650 GRE has 2,048 shading units, 128 texture mapping units, 64 ROPs, and 32 ray tracing cores. The RTX 4500 Ada Generation has 7,680 shading units, 240 TMUs, 80 ROPs, 60 RT cores, and 240 tensor cores. The NVIDIA card has 3.75 times the shading units, 1.875 times the TMUs, 1.25 times the ROPs, and 1.875 times the RT cores. The tensor cores on the NVIDIA card have no counterpart on the AMD card, which has none listed. The FP32 compute rating for the RX 7650 GRE is 22.08 TFLOPS, while the RTX 4500 Ada Generation delivers 39.63 TFLOPS, a 1.79 times advantage. Both cards have 1:1 FP16 to FP32 ratios, so the FP16 figures match their FP32 numbers.

The power and interface specs also differ. The RX 7650 GRE has a TDP of 170 W and uses a single 8-pin power connector, with a suggested PSU of 450 W. The RTX 4500 Ada Generation has a TDP of 210 W, no power connectors listed, and a suggested PSU of 550 W. The AMD card uses PCIe 4.0 x8, while the NVIDIA card uses PCIe 4.0 x16. The RX 7650 GRE outputs include 1x HDMI 2.1a and 3x DisplayPort 2.1. The RTX 4500 Ada Generation outputs are 4x DisplayPort 1.4a.

Where Each One Wins

Based on the recorded data, the RTX 4500 Ada Generation wins the only direct benchmark comparison. Its Geekbench OpenCL score of 160,786 more than doubles the RX 7650 GRE's 83,109. This compute-oriented result indicates the NVIDIA card is better suited for workloads that stress raw floating-point throughput and large memory buffers. Its 24 GB memory capacity and 432.0 GB/s bandwidth give it a clear advantage in data-heavy tasks, and its 39.63 TFLOPS FP32 rate is nearly double the AMD card's 22.08 TFLOPS.

The RX 7650 GRE does not win any recorded benchmark against the RTX 4500 Ada Generation. Its competitive position, based on the nearest rivals data, is against consumer cards like the RTX 4070 SUPER, where it sits within 1.2 percent in average score. The RX 7650 GRE also has the advantage of a smaller physical footprint, at 204 mm in length versus 245 mm for the NVIDIA card. Its lower TDP of 170 W versus 210 W means it draws less power, and its 450 W suggested PSU is lower than the 550 W suggested for the RTX 4500 Ada Generation.

The RTX 4500 Ada Generation also holds the edge in API coverage with its Geekbench Vulkan score of 171,401, which is not available for the AMD card in the database. The NVIDIA card's 240 tensor cores are present for AI-related workloads, a feature the RX 7650 GRE lacks entirely. For users who need those tensor core capabilities, the AMD card has no equivalent in its specification list.

The Verdict

The data directs a clear split between these two cards. The NVIDIA RTX 4500 Ada Generation is the stronger GPU by every measured performance metric in the database. It wins the only head-to-head benchmark, holds a 97th percentile ranking versus the AMD card's 83rd, and delivers roughly 3.9 times the average benchmark score. Its 24 GB memory, 432.0 GB/s bandwidth, and 39.63 TFLOPS FP32 rate place it firmly in workstation-class territory. The presence of 240 tensor cores and a Vulkan score of 171,401 further separate it from the AMD card.

The AMD Radeon RX 7650 GRE is a smaller, lower-power card. Its 170 W TDP, 204 mm length, and 450 W suggested PSU make it a more compact option. Its nearest rivals in the database are consumer cards like the RTX 4070 SUPER, and it sits within 1.3 percent of that group. For users who need a card that fits in a smaller chassis and draws less power, the RX 7650 GRE is the appropriate choice, but the performance gap to the RTX 4500 Ada Generation is not close.

For compute-heavy workloads, large datasets, or AI-related tasks that can use tensor cores, the RTX 4500 Ada Generation is the only rational pick based on the recorded measurements. For a more modest build where power draw and physical size matter more than raw throughput, the RX 7650 GRE serves that role. The two cards are not interchangeable, and the benchmark data does not suggest any scenario where the AMD card matches the NVIDIA card's compute output.
