AMD Radeon RX 7700S vs NVIDIA GeForce RTX 3080 Ti Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive sweep for the NVIDIA GeForce RTX 3080 Ti across every shared benchmark. In 3DMark Steel Nomad (DX12), the RTX 3080 Ti scores 5077 against the RX 7700S's 2185, a delta of 132.4%. That is not a narrow margin; it is a doubling of performance in a modern DirectX 12 workload, indicating a substantial rasterization advantage for the desktop-class NVIDIA part.

The gap widens further in compute-oriented tests. In Geekbench OpenCL, the RTX 3080 Ti records 170,037 points versus 62,983 for the RX 7700S, a 170% delta. This suggests the NVIDIA card's raw shader throughput and memory subsystem scale far better under generic compute loads. The most extreme difference appears in Geekbench Vulkan: the RTX 3080 Ti posts 192,697, while the RX 7700S manages only 36,380. That 429.7% delta is enormous and likely reflects both the NVIDIA card's higher FP32 throughput (34.10 TFLOPS vs 20.48 TFLOPS) and its much wider memory bus (384-bit vs 128-bit), which matters in Vulkan's lower-level API overhead.

However, the context matters. The RX 7700S is a mobile GPU, designed for laptops, while the RTX 3080 Ti is a desktop add-in board. The average benchmark score in the database for the RTX 3080 Ti is 41,187, placing it in the 83rd percentile of all GPUs. The RX 7700S averages 33,849, sitting in the 78th percentile. Despite the massive per-test deltas, the overall percentile gap is only 5 points, which shows that the RX 7700S, while slower, is still a capable performer relative to the entire GPU landscape, just not relative to this specific NVIDIA flagship.

Looking at the nearest rivals in the database helps calibrate expectations. The RTX 3080 Ti's closest competitor by average score is the AMD Radeon Pro 5300 at 40,870, a mere 0.8% delta, followed by the NVIDIA Tesla M40 24 GB at 41,707 (-1.2%) and the Tesla M40 at 41,897 (-1.7%). Notably, the NVIDIA GeForce RTX 5070 scores 40,377, putting the RTX 3080 Ti 2% ahead of it on average. For the RX 7700S, its nearest rival is the AMD Radeon HD 7950 at 33,951 (-0.3%), then the RX 480 at 33,997 (-0.4%), the GTX 1060 5 GB at 33,694 (+0.5%), and the RTX A5000 at 33,622 (+0.7%). These close deltas indicate that the RX 7700S performs in the same league as older mid-range desktop cards, while the RTX 3080 Ti competes with modern and professional high-end parts.

The Verdict

From the data alone, the choice is unambiguous for raw performance: the NVIDIA GeForce RTX 3080 Ti wins every recorded benchmark against the AMD Radeon RX 7700S, with deltas ranging from 132.4% to 429.7%. If the primary metric is frame rates, compute throughput, or API-specific performance, the RTX 3080 Ti is the superior product. The 3DMark Steel Nomad result alone, where the NVIDIA card more than doubles the AMD score, is enough to recommend it for any demanding DX12 gaming scenario.

But the verdict must also account for form factor and power. The RX 7700S is an integrated mobile part (IGP slot width, no power connectors, 100 W TDP) designed for portable devices. The RTX 3080 Ti is a dual-slot desktop card with a 350 W TDP, a 12-pin power connector, and a suggested 750 W PSU. These are not interchangeable products. The data shows the RTX 3080 Ti is faster, but it also shows it is a desktop-only solution. For a laptop user, the RX 7700S is the only viable option in this comparison, despite being significantly slower.

In terms of production status, the RTX 3080 Ti is end-of-life, while the RX 7700S is active. That means the AMD part is still in production and likely available in current mobile systems, whereas the NVIDIA card is being phased out in favor of its successor, the GeForce 40 series. The launch MSRP for the RTX 3080 Ti was 1,199 USD, but the RX 7700S has no recorded launch MSRP, so no price comparison is possible from the data.

Where Each One Wins

The RTX 3080 Ti wins in every measurable category in this dataset. Its strengths are most pronounced in Vulkan performance, where it leads by 429.7%, and OpenCL, where it leads by 170%. These results indicate that the NVIDIA card is better suited for compute-heavy applications, such as rendering, scientific simulation, or any workload that leverages generic GPU compute APIs. The 3DMark Steel Nomad win by 132.4% also shows a clear advantage in modern DX12 gaming, making it the better choice for high-refresh-rate or high-resolution gaming on desktop.

The RX 7700S, despite losing all head-to-head tests, still holds a positional advantage in its own right. As a mobile GPU with a 100 W TDP and no external power connectors, it is designed for thin-and-light laptops where the RTX 3080 Ti cannot physically fit or be powered. The data shows it is not a weak performer in absolute terms: its 33,849 average score places it in the 78th percentile of all GPUs, and its nearest rivals are older desktop cards like the RX 480 and GTX 1060 5 GB, which were considered solid mid-range options in their time. For a laptop user, the RX 7700S offers a level of performance that was only available in desktop PCs a few years ago.

The use-case split is therefore clear: the RTX 3080 Ti is for desktop builders who prioritize maximum performance and have the power delivery and cooling to support it. The RX 7700S is for mobile users who need a capable GPU in a portable chassis and are willing to accept lower absolute performance for the convenience of a laptop form factor.

Architecture Differences

The two GPUs come from fundamentally different architectural generations and design philosophies. The NVIDIA GeForce RTX 3080 Ti uses the GA102 chip built on Ampere architecture, fabricated on an 8 nm process at Samsung. It packs 28,300 million transistors into a 628 mm² die, yielding a transistor density of 45.1 million per mm². The AMD Radeon RX 7700S uses the Navi 33 chip on RDNA 3.0 architecture, produced on a 6 nm process at TSMC. It contains 13,300 million transistors on a much smaller 204 mm² die, achieving a higher density of 65.2 million per mm².

This density difference is notable: the AMD chip is more efficient in terms of transistors per area, but the NVIDIA chip has over twice the total transistor count. The RTX 3080 Ti also features dedicated tensor cores (320 of them) for AI workloads, which the RX 7700S lacks entirely, as its tensor core field is null. In ray tracing, the RTX 3080 Ti has 80 RT cores versus 32 for the RX 7700S, a 2.5x advantage that likely contributes to its strong performance in modern API tests.

The memory architectures are also divergent. The RTX 3080 Ti uses 12 GB of GDDR6X on a 384-bit bus, delivering 912.4 GB/s of bandwidth. The RX 7700S uses 8 GB of GDDR6 on a 128-bit bus, with 288.0 GB/s. This is a 3.2x bandwidth advantage for NVIDIA, which is critical for high-resolution textures and compute tasks. The RX 7700S does have a higher boost clock (2500 MHz vs 1665 MHz) and a game clock of 2200 MHz, but its smaller memory bus and lower shader count (2048 vs 10240) limit its overall throughput.

Specification Differences

The most obvious difference is in shading units: the RTX 3080 Ti has 10,240, while the RX 7700S has 2,048, a 5x gap. TMUs follow suit, with 320 on NVIDIA versus 128 on AMD. ROPs are 112 versus 64. The RTX 3080 Ti's pixel rate is 186.5 GPixel/s versus 160.0 GPixel/s for the RX 7700S, and its texture rate is 532.8 GTexel/s versus 320.0 GTexel/s. FP16 compute shows a reversal: the RX 7700S achieves 40.96 TFLOPS (2:1 ratio) versus 34.10 TFLOPS (1:1) for NVIDIA, but this does not translate to benchmark wins for AMD in the recorded tests.

Power consumption differs drastically. The RTX 3080 Ti has a 350 W TDP, requires a 750 W suggested PSU, and uses a single 12-pin connector. The RX 7700S has a 100 W TDP, requires no power connectors, and has no suggested PSU listed. The form factors are incompatible: the NVIDIA card is dual-slot with dimensions of 285 mm length, 112 mm height, and 40 mm width, while the AMD part is listed as IGP with no dimensions. Display outputs also differ: the RTX 3080 Ti offers 1x HDMI 2.1 and 3x DisplayPort 1.4a, while the RX 7700S is "Portable Device Dependent." Both support PCIe 4.0 x16 and share the same API feature set: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.
