AMD Radeon RX 7700S vs NVIDIA GeForce RTX 4080 SUPER Comparison

# Head-to-Head Benchmarks

The data presents a decisive picture in every measured test, with the NVIDIA GeForce RTX 4080 SUPER winning all three head-to-head benchmarks by a wide margin. In 3DMark Steel Nomad DX12, the RTX 4080 SUPER scores 6600 against the RX 7700S’s 2185, a delta of 202.1%. That is not a marginal lead; it is a threefold performance advantage in a modern DirectX 12 workload. The gap suggests the RX 7700S is operating in a completely different performance tier, likely due to its mobile-oriented design.

Geekbench OpenCL shows an even larger separation. The RTX 4080 SUPER records 246994, while the RX 7700S manages 69728 — a 254.2% delta. This is the single biggest win for NVIDIA in the dataset. OpenCL compute workloads often scale with raw shader throughput and memory bandwidth, and the numbers align with the RTX 4080 SUPER’s far larger execution resources. The RX 7700S’s 20.48 TFLOPS FP32 peak is less than half of the RTX 4080 SUPER’s 52.22 TFLOPS, and the benchmark reflects that disparity almost exactly.

Geekbench Vulkan narrows the gap somewhat but still favors NVIDIA heavily. The RTX 4080 SUPER scores 226163 versus 85603, a 164.2% delta. Vulkan’s lower overhead can sometimes help smaller GPUs close distance, but here the architectural and resource gap is too large. Interestingly, the RX 7700S’s Vulkan score (85603) is higher than its OpenCL score (69728), suggesting the AMD card’s RDNA 3.0 architecture handles Vulkan’s explicit control model relatively better than OpenCL’s more generic compute paths. Still, the RTX 4080 SUPER’s Vulkan result remains 2.64 times higher.

Across all three tests, the wins tally is 3-0 in favor of NVIDIA. The weakest NVIDIA margin is still above 164%, meaning there is no scenario in this dataset where the RX 7700S comes within even two-thirds of the RTX 4080 SUPER’s performance. For context on the broader field, the RTX 4080 SUPER’s average benchmark score is 53610, placing it just 0.2% above the AMD Radeon RX 6900 XT (53489) and 2.1% above the RX 7700S (52505). The RX 7700S, meanwhile, sits 0.8% above the NVIDIA GeForce RTX 5070 Ti (52086) and is 1.7% behind the AMD Radeon Pro W6600M (53414). So while the head-to-head results are lopsided, the average scores show the RX 7700S is not an outlier — it trades blows with other mid-range parts, but the RTX 4080 SUPER occupies a distinctly higher performance stratum.

# Architecture Differences

The two GPUs come from fundamentally different design philosophies. The RTX 4080 SUPER uses the AD103 chip on TSMC’s 5 nm process, while the RX 7700S relies on the Navi 33 chip on TSMC’s 6 nm node. That process gap matters: the smaller 5 nm node allows NVIDIA to pack 45,900 million transistors into a 379 mm² die, yielding a transistor density of 121.1 million per mm². AMD’s Navi 33, by contrast, contains 13,300 million transistors on a 204 mm² die, at 65.2 million per mm². The RTX 4080 SUPER has nearly 3.5 times the transistor count and almost double the density, which explains its massive resource advantage.

The memory subsystems diverge sharply. The RTX 4080 SUPER offers 16 GB of GDDR6X on a 256-bit bus, delivering 736.3 GB/s of bandwidth. The RX 7700S has 8 GB of GDDR6 on a 128-bit bus, at 288.0 GB/s. That 2.56x bandwidth advantage for NVIDIA is critical for high-resolution gaming and compute workloads. Memory clock rates also differ: the RTX 4080 SUPER runs at 1438 MHz (23 Gbps effective), while the RX 7700S runs at 2250 MHz (18 Gbps effective). The AMD card’s higher raw memory clock is irrelevant given its narrower bus and slower effective data rate.

Compute resources tell a similar story. The RTX 4080 SUPER fields 10240 shading units, 320 TMUs, and 112 ROPs, against the RX 7700S’s 2048 shaders, 128 TMUs, and 64 ROPs. NVIDIA’s RT cores number 80 versus AMD’s 32, and NVIDIA adds 320 tensor cores while AMD has none. Pixel rate is 285.6 GPixel/s for NVIDIA versus 160.0 GPixel/s for AMD; texture rate is 816.0 GTexel/s versus 320.0 GTexel/s. FP32 throughput is 52.22 TFLOPS versus 20.48 TFLOPS. Interestingly, the RX 7700S’s FP16 rate of 40.96 TFLOPS is double its FP32, indicating a 2:1 ratio, whereas the RTX 4080 SUPER runs FP16 at 1:1 with FP32 (52.22 TFLOPS). This means AMD has a theoretical advantage in half-precision workloads, but the raw numbers still favor NVIDIA.

The RX 7700S is a mobile part, as its "IGP" slot width and "Portable Device Dependent" display outputs suggest. Its TDP is 100 W, versus 320 W for the RTX 4080 SUPER. The RTX 4080 SUPER requires a 16-pin power connector and a 700 W suggested PSU, while the RX 7700S uses no external power connectors. The RTX 4080 SUPER is triple-slot, 310 mm long, and has been declared end-of-life, while the RX 7700S remains active. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, and both use PCIe 4.0 x16.

# Where Each One Wins

The data leaves little room for ambiguity: the RTX 4080 SUPER wins every benchmark in the head-to-head set. In 3DMark Steel Nomad DX12, it is 202.1% ahead, which translates to roughly three times the frame rate in a modern DirectX 12 game scenario. That makes it the clear choice for high-refresh-rate 1440p or 4K gaming, where the 736.3 GB/s bandwidth and 52.22 TFLOPS FP32 throughput can be fully utilized. The Geekbench OpenCL result (254.2% lead) indicates NVIDIA is also dominant for general-purpose GPU compute, including rendering, simulation, and machine learning inference.

The RX 7700S, despite losing all three head-to-head tests, still has a role. Its 100 W TDP and lack of external power connectors make it suitable for thin-and-light laptops where power efficiency is paramount. Its FP16 rate of 40.96 TFLOPS is double its FP32, a feature that could benefit certain AI or scientific workloads that use half precision — but only if the software is optimized for RDNA 3.0’s 2:1 FP16 path. The RX 7700S’s Vulkan score, while 164.2% behind NVIDIA, is still 22.8% higher than its own OpenCL score, suggesting it handles Vulkan-based games and applications relatively well.

For users who prioritize portability and battery life over raw performance, the RX 7700S’s 8 GB GDDR6 and 288.0 GB/s bandwidth are adequate for 1080p gaming at medium-to-high settings. Its 2048 shading units and 32 RT cores support DirectX 12 Ultimate features, including ray tracing, though with far less headroom than NVIDIA’s 80 RT cores. The RX 7700S also has a higher base clock relative to its boost (1500 MHz base, 2500 MHz boost) compared to NVIDIA’s (2295 MHz base, 2550 MHz boost), but this does not compensate for the resource gap.

The RTX 4080 SUPER is the unambiguous winner for any workload that demands maximum performance. Its 16 GB VRAM is double the RX 7700S’s, and its bandwidth advantage is even larger. The 3DMark Steel Nomad result, which stresses both graphics and compute, shows a 202.1% lead that will only grow in memory-bound scenarios. The RTX 4080 SUPER’s tensor cores are absent on the RX 7700S entirely, making NVIDIA the only option for DLSS-style AI acceleration in this comparison.

# The Verdict

The data is unambiguous: the NVIDIA GeForce RTX 4080 SUPER outperforms the AMD Radeon RX 7700S in every measured test, with deltas ranging from 164.2% to 254.2%. The RTX 4080 SUPER’s average benchmark score of 53610 places it 2.1% above the RX 7700S’s 52505, but that average masks the true extent of the head-to-head dominance — the average score includes only three tests, all of which NVIDIA wins decisively. The RX 7700S’s nearest rivals include the NVIDIA GeForce RTX 5070 Ti (52086, 0.8% lower) and the AMD Radeon Pro W6600M (53414, 1.7% higher), which suggests it is competitive with mid-range desktop parts, but the RTX 4080 SUPER is in a different league.

For a desktop workstation or high-end gaming rig, the RTX 4080 SUPER is the only rational choice from this dataset. Its 320 W TDP and triple-slot cooler are acceptable trade-offs for its 52.22 TFLOPS FP32 and 736.3 GB/s bandwidth. For a laptop, the RX 7700S’s 100 W TDP and IGP form factor are compelling, but the performance cost is steep — you are sacrificing roughly 2.5x to 3.5x performance depending on the workload. The RTX 4080 SUPER’s end-of-life status may concern some, but its successor (GeForce 50) is already in the market, and the 4080 SUPER remains the stronger card here.

The RX 7700S’s only theoretical advantage is its 2:1 FP16 ratio (40.96 TFLOPS versus 52.22 TFLOPS for NVIDIA at FP16), but even that is a losing proposition in absolute terms. The RTX 4080 SUPER has 320 tensor cores that the RX 7700S lacks entirely, giving NVIDIA a hardware path for AI acceleration that AMD cannot match. If the choice is strictly between these two, the verdict is clear: the RTX 4080 SUPER wins on every metric that matters, and the RX 7700S only makes sense where power constraints are absolute.
