AMD Radeon RX 7650 GRE vs NVIDIA GeForce RTX 5080 Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive margin in favor of the NVIDIA GeForce RTX 5080 across the two shared benchmark tests. In 3DMark Steel Nomad (DX12), the RTX 5080 scores 8,637 points against the AMD Radeon RX 7650 GRE's 2,336 points, a delta of 269.7%. That is not a close contest; it is a generational gap expressed in raw rendering throughput. The Geekbench OpenCL result tells a similar story, with the RTX 5080 posting 235,901 points versus 83,109 for the RX 7650 GRE, a 183.8% advantage. Both wins belong to NVIDIA, and the database records 2 wins for the RTX 5080 and 0 for the AMD card.

To put those numbers in context, the RTX 5080's average benchmark score sits at 56,083, placing it in the 87th percentile of all GPUs tracked. Its nearest rival, the AMD Radeon 8060S, averages 55,757, a mere 0.6% gap, which means the RTX 5080 is barely ahead of that competitor. The AMD Radeon RX 9070 GRE actually outpaces it by 2.2% with an average score of 57,367. So while the RTX 5080 dominates the RX 7650 GRE, it is not the absolute top of the database hierarchy; it sits in a tightly contested band.

The RX 7650 GRE, by contrast, averages 42,723 points, good for the 83rd percentile. Its nearest rival is the NVIDIA GeForce RTX 4070 SUPER at 43,223 points, which is 1.2% ahead. The NVIDIA Quadro M6000 24 GB, RTX 5050 Mobile, and Quadro M6000 all cluster within 1.3% of the AMD card's score. This means the RX 7650 GRE is not dramatically slower than those cards in aggregate, but the gap to the RTX 5080 is enormous: roughly 31% lower average score (56,083 vs 42,723). The head-to-head deltas of 269.7% and 183.8% are the clearest signals here; the RTX 5080 is in a different performance class entirely.

Architecture Differences

The two cards diverge at the silicon level. The RTX 5080 uses the GB203 chip built on TSMC's 5 nm process, packing 45,600 million transistors into a 378 mm² die. That yields a transistor density of 120.6 million per square millimeter. The architecture is Blackwell 2.0, part of the GeForce 50-series. The RX 7650 GRE uses the Navi 33 chip on TSMC's 6 nm process, with 13,300 million transistors on a 204 mm² die, for a density of 65.2 million per square millimeter. Its architecture is RDNA 3.0, codenamed "Hotpink Bonefish," part of the Radeon RX 7000 series. The process node difference (5 nm vs 6 nm) and transistor count gap (3.4x more on the NVIDIA side) explain much of the performance disparity.

Core counts follow the same pattern. The RTX 5080 has 10,752 shading units, 336 texture mapping units, and 112 raster output units. It also carries 84 RT cores and 336 tensor cores. The RX 7650 GRE has 2,048 shading units, 128 TMUs, and 64 ROPs, with 32 RT cores and no dedicated tensor cores. The FP32 throughput is 56.28 TFLOPS for the RTX 5080 versus 22.08 TFLOPS for the AMD card, and both list FP16 at a 1:1 ratio. The NVIDIA card's pixel rate is 293.1 GPixel/s versus 172.5 GPixel/s, and its texture rate is 879.3 GTexel/s versus 345.0 GTexel/s.

Memory is another major differentiator. The RTX 5080 has 16 GB of GDDR7 on a 256-bit bus, delivering 960.0 GB/s of bandwidth. The RX 7650 GRE has 8 GB of GDDR6 on a 128-bit bus, with 288.0 GB/s. That is a 3.3x bandwidth advantage for NVIDIA. Clock speeds are closer than the core counts suggest: the RTX 5080 boosts to 2,617 MHz, while the RX 7650 GRE boosts to 2,695 MHz, but the AMD card's base clock is 1,720 MHz versus 2,295 MHz for NVIDIA. The AMD card also lists a game clock of 2,350 MHz, a figure the NVIDIA card does not report.

Power and interface specs differ as well. The RTX 5080 has a TDP of 360 W, requires a 750 W PSU, and uses a single 16-pin connector. The RX 7650 GRE has a TDP of 170 W, needs a 450 W PSU, and uses a single 8-pin connector. The RTX 5080 is a dual-slot card measuring 304 mm by 137 mm by 40 mm, while the RX 7650 GRE is also dual-slot but shorter at 204 mm by 115 mm, with no width listed. The bus interface is PCIe 5.0 x16 for NVIDIA and PCIe 4.0 x8 for AMD. Both support DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. Display outputs are similar: one HDMI 2.1b and three DisplayPort 2.1b on the RTX 5080, versus one HDMI 2.1a and three DisplayPort 2.1 on the RX 7650 GRE.

Where Each One Wins

The RTX 5080 wins every recorded benchmark where both cards appear. In 3DMark Steel Nomad, the DX12 workload favors the NVIDIA card by a factor of 3.7x in raw score. This suggests it is the stronger choice for modern DX12 gaming and synthetic load tests that stress rasterization and compute. Its 16 GB of GDDR7 memory and 960 GB/s bandwidth also point to advantages in high-resolution textures and memory-heavy scenes, though the database does not include direct gaming benchmarks to confirm that. The Geekbench OpenCL result, a compute-oriented test, shows a 183.8% lead, meaning the RTX 5080 is also the better pick for OpenCL compute workloads such as rendering, simulation, or machine learning inference that rely on general-purpose GPU compute.

The RX 7650 GRE has no benchmark wins in the shared tests. Its strengths are qualitative rather than quantitative from the recorded data. Its lower TDP of 170 W and 450 W PSU requirement make it a lighter load on system power delivery compared to the RTX 5080's 360 W TDP and 750 W PSU recommendation. Its shorter length (204 mm versus 304 mm) makes it easier to fit in compact cases. It also has a higher boost clock (2,695 MHz versus 2,617 MHz), but that does not translate into any benchmark victory. The RDNA 3.0 architecture includes 32 RT cores, so ray tracing is supported, but the RTX 5080 has 84 RT cores, and the performance gap in the shared tests suggests the AMD card would fall behind in RT-heavy workloads, though no such test appears in the database.

For users who need maximum performance in DX12 and OpenCL, the RTX 5080 is the clear winner. For those who prioritize lower power draw, smaller physical footprint, and a simpler 8-pin power connector, the RX 7650 GRE has practical advantages, but those are not reflected in any benchmark score. The data shows no scenario where the RX 7650 GRE outperforms the RTX 5080 in measured tests.

The Verdict

The database is unambiguous: the NVIDIA GeForce RTX 5080 outperforms the AMD Radeon RX 7650 GRE in every shared benchmark, with deltas of 269.7% in 3DMark Steel Nomad and 183.8% in Geekbench OpenCL. The RTX 5080 also holds a higher average benchmark score (56,083 vs 42,723) and a higher percentile ranking (87th vs 83rd). Anyone selecting between these two on performance alone should choose the RTX 5080 without hesitation.

The RX 7650 GRE is not without merit, but its merits are not performance-based in the recorded data. It is a lower-power card (170 W TDP versus 360 W), requires a less demanding PSU (450 W versus 750 W), uses a standard 8-pin connector instead of a 16-pin, and is physically shorter. Those factors matter for specific builds, such as small-form-factor systems or upgrades with older power supplies. But the benchmark results show a 31% gap in average score and a 269.7% gap in the primary DX12 test. The RX 7650 GRE sits close to the RTX 4070 SUPER, RTX 5050 Mobile, and Quadro M6000 in average score, meaning it competes with those cards, not with the RTX 5080.

The verdict is straightforward. If the goal is maximum frames, compute throughput, or DX12 performance, the RTX 5080 is the only choice. If the goal is a compact, low-power card that still delivers 83rd-percentile performance, the RX 7650 GRE is a viable alternative, but it will not match the RTX 5080 in any measured metric. The data does not support any other conclusion.
