AMD Radeon RX 7700S vs NVIDIA GeForce RTX 5080 Mobile Comparison

Head-to-Head Benchmarks

The recorded data for these two mobile GPUs is lopsided in a way that is rarely seen in direct comparisons. Across the three shared benchmark tests, the NVIDIA GeForce RTX 5080 Mobile wins every single contest, and the margins are substantial. In 3DMark Steel Nomad (DX12), the RTX 5080 Mobile scores 4,952 against 2,185 for the AMD Radeon RX 7700S. That is a delta of 126.6%, meaning the NVIDIA part delivers more than double the frame throughput in this demanding modern workload.

The gap widens further in compute-oriented tests. In Geekbench OpenCL, the RTX 5080 Mobile posts 166,986 points, while the RX 7700S manages 62,983. The delta here is 165.1%, so the NVIDIA GPU is roughly 2.65 times faster in raw general-purpose compute as measured by this test. The most extreme difference appears in Geekbench Vulkan, where the RTX 5080 Mobile reaches 169,754 points against 36,380 for the AMD part, a delta of 366.6%. That is a nearly 4.7x advantage in Vulkan compute throughput. The data suggests the architecture differences between Blackwell 2.0 and RDNA 3.0 manifest very strongly in API-level compute workloads, not just in rasterization.

It is worth noting what these deltas mean relative to each GPU's own peer group. The RTX 5080 Mobile sits at the 81st percentile among all GPUs in the database, with an average benchmark score of 38,349. Its nearest rivals include the GeForce RTX 4080 Mobile (average score 38,135, delta 0.6%) and the GeForce MX570 (38,299, delta 0.1%). The RX 7700S, by contrast, ranks at the 78th percentile with an average score of 33,849, placing it near the GeForce GTX 1060 5 GB (33,694, delta 0.5%) and the RTX A5000 (33,622, delta 0.7%). So while the RX 7700S is not a weak GPU in absolute terms, the RTX 5080 Mobile is operating in a higher performance tier entirely.

Where Each One Wins

Given the head-to-head results, the RTX 5080 Mobile is the clear winner in every measured category. The 3DMark Steel Nomad result indicates superior DX12 gaming performance, particularly in scenes with heavy geometry and ray tracing effects. The Geekbench OpenCL and Vulkan results show that the NVIDIA part also dominates in compute-heavy tasks such as physics simulations, video encoding pipelines, and machine learning inference workloads that leverage OpenCL or Vulkan compute queues.

The RX 7700S does not win any of the three shared tests, but its profile still has a niche. With a lower transistor count (13,300 million versus 45,600 million) and a smaller die (204 mm² versus 378 mm²), it is a more compact design. Its 100 W TDP is higher than the 80 W TDP of the RTX 5080 Mobile, but the AMD part draws power across a smaller transistor budget, which may make it easier to integrate into thinner chassis designs that do not require the same thermal headroom. The RX 7700S also has a higher boost clock (2500 MHz versus 1500 MHz), which suggests it can scale frequency more aggressively in short bursts, even if the sustained throughput is far lower.

For users who prioritize pure performance in the three benchmark categories recorded, the RTX 5080 Mobile is the only choice. For users who need a GPU that fits into a compact mobile platform with lower absolute performance expectations, the RX 7700S remains a functional option, but the data does not support any scenario where it outruns the NVIDIA part in these tests.

Architecture Differences

The two GPUs come from fundamentally different design philosophies. The RTX 5080 Mobile is built on the GB203 chip using Blackwell 2.0 architecture, fabricated on a 5 nm process at TSMC. It packs 45,600 million transistors into a 378 mm² die, giving a transistor density of 120.6 million per square millimeter. The RX 7700S uses the Navi 33 chip with RDNA 3.0 architecture (codename "Hotpink Bonefish"), also from TSMC but on a 6 nm process. It contains 13,300 million transistors on a 204 mm² die, for a density of 65.2 million per square millimeter. The NVIDIA chip has roughly 3.4 times more transistors and 1.85 times the die area, explaining much of its performance advantage.

Memory configurations differ sharply as well. The RTX 5080 Mobile uses 16 GB of GDDR7 memory on a 256-bit bus, delivering 896.0 GB/s of bandwidth. The RX 7700S has 8 GB of GDDR6 on a 128-bit bus, yielding 288.0 GB/s. The NVIDIA part offers more than triple the memory bandwidth, which is critical for high-resolution gaming and data-heavy compute tasks. The memory clock also differs: 1750 MHz (28 Gbps effective) for the RTX 5080 Mobile versus 2250 MHz (18 Gbps effective) for the RX 7700S. Despite the lower memory clock, the wider bus gives the NVIDIA GPU the decisive bandwidth advantage.

The compute resource counts are also heavily skewed. The RTX 5080 Mobile has 7,680 shading units, 240 texture mapping units, and 96 raster output units. It also features 60 ray tracing cores and 240 tensor cores. The RX 7700S has 2,048 shading units, 128 TMUs, and 64 ROPs, with 32 ray tracing cores and no tensor cores listed. The pixel rate favors the AMD part slightly (160.0 GPixel/s versus 144.0 GPixel/s), but the texture rate favors NVIDIA (360.0 GTexel/s versus 320.0 GTexel/s). In raw FP32 throughput, the RTX 5080 Mobile achieves 23.04 TFLOPS versus 20.48 TFLOPS for the RX 7700S. The FP16 numbers tell a different story: the AMD GPU reaches 40.96 TFLOPS with a 2:1 ratio, while the NVIDIA part is capped at 23.04 TFLOPS with a 1:1 ratio. This means the RX 7700S has a theoretical advantage in FP16 workloads, though no head-to-head test in the database covers that scenario.

The bus interface also differs: PCIe 5.0 x16 for the NVIDIA GPU versus PCIe 4.0 x16 for the AMD part. Both are listed as IGP slot width with no power connectors, and both rely on portable device dependent display outputs. The API support is identical: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The Verdict

The data is unambiguous. The RTX 5080 Mobile outperforms the RX 7700S by a massive margin in every recorded benchmark, with deltas ranging from 126.6% to 366.6%. For any user choosing between these two based on performance, the NVIDIA GPU is the correct pick. The 3DMark Steel Nomad result shows a 126.6% lead in modern DX12 gaming, which translates to playable frame rates where the AMD part would struggle. The Geekbench results show even larger gaps in compute, making the RTX 5080 Mobile the better choice for content creation, scientific computing, or any workload that uses OpenCL or Vulkan.

The RX 7700S does have a lower transistor count and smaller die, which could appeal to system integrators looking to minimize cost or physical footprint. Its higher boost clock (2500 MHz versus 1500 MHz) and higher TDP (100 W versus 80 W) suggest it is tuned for a different power envelope. However, the recorded performance data does not provide any scenario where the RX 7700S wins. The 78th percentile ranking is respectable, but the 81st percentile for the RTX 5080 Mobile, combined with the enormous head-to-head deltas, leaves no ambiguity. If the choice is between these two GPUs and performance is the sole criterion, the RTX 5080 Mobile is the definitive answer.
