AMD Radeon RX 7650 GRE vs NVIDIA GeForce RTX 3080 Ti Comparison

The AMD Radeon RX 7650 GRE and the NVIDIA GeForce RTX 3080 Ti occupy different corners of the GPU landscape, yet both sit in the 83rd percentile of all GPUs according to the data. The RX 7650 GRE is a current-generation RDNA 3.0 part aimed at mainstream resolutions, while the RTX 3080 Ti is an end-of-life Ampere flagship. Benchmark results show a stark performance gap, but the comparison reveals more than just a raw speed difference; it highlights how architecture, memory configuration, and production status define their respective roles.

Where Each One Wins

The RTX 3080 Ti wins every head-to-head benchmark in the data, and it wins by wide margins. In the 3DMark Steel Nomad DX12 test, the NVIDIA card scores 5,077 points against the AMD card's 2,336 points, a delta of -54% for the RX 7650 GRE. The Geekbench OpenCL result tells a similar story: 170,037 for the RTX 3080 Ti versus 83,109 for the RX 7650 GRE, a -51.1% delta. These are not close contests; they are decisive victories for the older, larger NVIDIA chip.

However, the RX 7650 GRE is not without its own territory. It is a far more compact and efficient design. The AMD card measures 204 mm in length and 115 mm in height, compared to the RTX 3080 Ti's 285 mm length and 112 mm height, with a 40 mm width. The RX 7650 GRE requires a single 8-pin power connector and a 450 W suggested PSU, while the RTX 3080 Ti needs a 12-pin connector and a 750 W suggested PSU. For builds where space is tight or power delivery is modest, the RX 7650 GRE is the only realistic choice between the two.

The AMD card also represents the current production generation. Its release date is 2025-02-06, and its production status is "Active," whereas the RTX 3080 Ti was released on 2021-05-30 and is marked "End-of-life." The RX 7650 GRE has a successor in Navi IV, while the RTX 3080 Ti's successor is the GeForce 40 series. In terms of platform longevity and driver support going forward, the RX 7650 GRE is the card that is still in production.

The Verdict

The data is unambiguous: the RTX 3080 Ti is the faster GPU in every measured benchmark. It delivers roughly double the performance in both the Steel Nomad DX12 test and the Geekbench OpenCL test. Anyone prioritizing raw frame rates or compute throughput should pick the RTX 3080 Ti, provided their system can handle its 350 W TDP and 750 W suggested PSU requirement. The 12 GB GDDR6X memory on a 384-bit bus with 912.4 GB/s bandwidth is a massive advantage over the RX 7650 GRE's 8 GB GDDR6 on a 128-bit bus with 288.0 GB/s.

The RX 7650 GRE is for a different user. Its 170 W TDP, single 8-pin connector, and compact 204 mm length make it suitable for small-form-factor builds or systems with older PSUs. It is also the only one of the two that is currently in production, which may matter for warranty and availability. The RX 7650 GRE's launch MSRP is 279 USD. The RTX 3080 Ti's launch MSRP was 1,199 USD, but it is no longer manufactured, so its market availability is limited to remaining stock or used units.

If the benchmark scores are the only criterion, the RTX 3080 Ti wins outright. If the criteria include power draw, physical size, and production status, the RX 7650 GRE becomes the sensible option for a new, compact build. There is no scenario in the data where the RX 7650 GRE outperforms the RTX 3080 Ti in raw performance.

Head-to-Head Benchmarks

The 3DMark Steel Nomad DX12 test is the most demanding workload in the comparison. The RTX 3080 Ti scores 5,077, which is more than double the RX 7650 GRE's 2,336. The -54% delta places the AMD card at less than half the performance of the NVIDIA card in this modern DX12 rasterization test. This is consistent with the hardware specifications: the RTX 3080 Ti has 10,240 shading units, 320 TMUs, and 112 ROPs, against the RX 7650 GRE's 2,048 shading units, 128 TMUs, and 64 ROPs. The NVIDIA card also has 80 RT cores and 320 tensor cores, while the AMD card has 32 RT cores and no tensor cores.

The Geekbench OpenCL test shows a similar pattern. The RTX 3080 Ti scores 170,037, and the RX 7650 GRE scores 83,109, a -51.1% delta. This compute-oriented workload reflects the FP32 throughput difference: the RTX 3080 Ti is rated at 34.10 TFLOPS, while the RX 7650 GRE is rated at 22.08 TFLOPS. The NVIDIA card also has a significant memory bandwidth advantage at 912.4 GB/s versus 288.0 GB/s, which helps in memory-heavy compute tasks.

The RTX 3080 Ti also has additional benchmark data that the RX 7650 GRE lacks. In Geekbench Vulkan, it scores 192,697. In Passmark tests, it scores 26,896 in G3D, 15,282 in GPU Compute, and 1,091 in G2D. These additional data points are not available for the RX 7650 GRE, so no direct comparison is possible, but they indicate the NVIDIA card's breadth of testing coverage. The RX 7650 GRE's average benchmark score is 42,723, while the RTX 3080 Ti's is 41,187, which is notable because the RTX 3080 Ti's average is dragged down by the inclusion of many lower-scoring Passmark legacy tests.

FAQ

Architecture Differences

The two GPUs come from fundamentally different design philosophies. The AMD Radeon RX 7650 GRE is built on the RDNA 3.0 architecture, using the Navi 33 chip on a 6 nm process from TSMC. It contains 13,300 million transistors on a 204 mm² die, giving a transistor density of 65.2M per mm². The NVIDIA GeForce RTX 3080 Ti uses the Ampere architecture with the GA102 chip on an 8 nm process from Samsung. It packs 28,300 million transistors on a 628 mm² die, with a density of 45.1M per mm². The AMD chip is smaller and denser, while the NVIDIA chip is physically much larger.

The compute resources differ dramatically. The RX 7650 GRE has 2,048 shading units, 128 TMUs, 64 ROPs, and 32 RT cores. The RTX 3080 Ti has 10,240 shading units, 320 TMUs, 112 ROPs, 80 RT cores, and 320 tensor cores. The NVIDIA card also supports FP16 at the same rate as FP32, with both rated at 34.10 TFLOPS, while the AMD card offers 22.08 TFLOPS for both FP32 and FP16. The pixel rate favors the NVIDIA card at 186.5 GPixel/s versus 172.5 GPixel/s, and the texture rate is 532.8 GTexel/s versus 345.0 GTexel/s.

Memory architecture is another major divide. The RX 7650 GRE uses 8 GB of GDDR6 on a 128-bit bus, while the RTX 3080 Ti uses 12 GB of GDDR6X on a 384-bit bus. This yields bandwidth of 288.0 GB/s versus 912.4 GB/s, a 3.2x advantage for the NVIDIA card. The bus interface also differs: the RX 7650 GRE uses PCIe 4.0 x8, while the RTX 3080 Ti uses PCIe 4.0 x16. Display outputs are similar in count but different in version: the AMD card offers 1x HDMI 2.1a and 3x DisplayPort 2.1, while the NVIDIA card offers 1x HDMI 2.1 and 3x DisplayPort 1.4a.

The clock speeds tell a story of power efficiency versus raw throughput. The RX 7650 GRE has a base clock of 1720 MHz and a boost clock of 2695 MHz, with a game clock of 2350 MHz. The RTX 3080 Ti has a base clock of 1365 MHz and a boost clock of 1665 MHz. The AMD card runs much faster but has far fewer execution units. The RTX 3080 Ti compensates with sheer scale, and its memory clock runs at 1188 MHz with 19 Gbps effective speed, while the AMD card's memory runs at 2250 MHz with 18 Gbps effective. The TDP difference is 170 W for the AMD card versus 350 W for the NVIDIA card, reflecting the NVIDIA chip's larger size and higher power draw.
