AMD Radeon RX 7700S vs NVIDIA GeForce RTX 4090 Mobile Comparison

Head-to-Head Benchmarks

The recorded data shows a stark performance separation between these two mobile graphics solutions. In the two directly comparable benchmark tests, the NVIDIA GeForce RTX 4090 Mobile wins both, and the margins are substantial.

The Geekbench OpenCL test shows the RTX 4090 Mobile scoring 180,831 against the Radeon RX 7700S at 62,983. That translates to a 187.1% advantage for the NVIDIA part. This is not a narrow lead, it is a near-threefold gap in raw compute throughput as measured by this workload. The OpenCL result typically reflects general-purpose compute performance, so the implication is that the RTX 4090 Mobile dominates in tasks that leverage the GPU for non-graphics processing.

The Geekbench Vulkan test widens the gap even further. Here the RTX 4090 Mobile scores 170,774 while the RX 7700S manages 36,380. The delta is 369.4% in favor of NVIDIA. Vulkan is a low-level graphics API, and such a massive difference suggests that the NVIDIA architecture extracts far more performance from the same API workload. It also hints at driver maturity or hardware scheduling advantages that RDNA 3.0 cannot offset in this particular test.

Looking at the broader benchmark averages, the RTX 4090 Mobile holds an average benchmark score of 43,667 across all its recorded tests. The RX 7700S averages 33,849 across its recorded tests. That is a meaningful difference, though less dramatic than the head-to-head deltas because each GPU has a different set of applicable tests in the database. The RTX 4090 Mobile also sits at the 84th percentile among all GPUs, while the RX 7700S sits at the 78th percentile. Both are above average, but the NVIDIA part is clearly positioned higher in the overall distribution.

The nearest rivals for each card put the gap into context. The RTX 4090 Mobile's closest competitors include the NVIDIA RTX A6000 with an average score of 44,075 (0.9% ahead of the mobile 4090), and the Quadro M6000 at 43,301 (0.8% behind). The RX 7700S, by contrast, is clustered with much older parts: the Radeon HD 7950 at 33,951 (0.3% ahead), the Radeon RX 480 at 33,997 (0.4% ahead), and the GeForce GTX 1060 5 GB at 33,694 (0.5% behind). The company the RX 7700S keeps in the database is from a different era entirely, which reinforces how far ahead the RTX 4090 Mobile sits in raw performance.

The RTX 4090 Mobile also has a wider recorded benchmark portfolio. It has nine entries covering OpenCL, Vulkan, DirectX 9, 10, 11, 12, G2D, G3D, and compute. The RX 7700S has only three recorded tests: 3DMark Steel Nomad DX12, OpenCL, and Vulkan. The absence of DirectX and compute entries for the AMD part makes direct comparison difficult outside the two shared workloads, but the shared tests are decisive enough.

The Verdict

The data points to a clear hierarchy. The NVIDIA GeForce RTX 4090 Mobile is in a different performance class than the AMD Radeon RX 7700S. Every shared benchmark result favors NVIDIA, with deltas of 187.1% and 369.4%. The average benchmark scores reinforce this: 43,667 versus 33,849. The percentile ranking also favors NVIDIA (84th versus 78th).

Who should choose the RTX 4090 Mobile? Anyone whose workload prioritizes maximum compute throughput and Vulkan graphics performance. The Geekbench Vulkan result, in particular, shows an extraordinary lead that suggests NVIDIA's architecture is far more efficient at translating hardware resources into actual frame or compute throughput under that API. Users who run OpenCL-based applications, which is common in scientific computing, rendering, and some content creation pipelines, will see a near-threefold advantage.

Who should choose the RX 7700S? The data does not favor it in any recorded benchmark. There is no test in the database where the AMD part wins. That said, the RX 7700S is not a weak GPU in absolute terms; its 78th percentile ranking places it above the majority of GPUs in the database. It is simply outclassed by the specific NVIDIA part in question. Users who are deciding between these two specific cards, and who have no constraint other than performance, should select the RTX 4090 Mobile based on the recorded data.

One caveat: the RTX 4090 Mobile has a 120 W TDP while the RX 7700S has a 100 W TDP. The NVIDIA part draws more power, and that may matter in thin-and-light chassis where thermal headroom is limited. The database does not record cooling capability or real-world sustained clocks, so the impact of the higher TDP on actual performance in a specific laptop cannot be quantified here.

Where Each One Wins

The RTX 4090 Mobile wins in every recorded head-to-head category. In OpenCL, its 180,831 score versus 62,983 gives it a 187.1% lead. In Vulkan, its 170,774 versus 36,380 gives it a 369.4% lead. There is no benchmark in the database where the RX 7700S comes out ahead.

The RTX 4090 Mobile also has the advantage of a much larger recorded test suite. Its Passmark G3D score of 27,212, DirectX 11 score of 262, DirectX 9 score of 310, and GPU compute score of 12,347 all sit in the database as evidence of broad capability. The RX 7700S has only a single 3DMark result (2,185 in Steel Nomad DX12) plus the two Geekbench entries. This means the AMD card's strengths, if any, are not captured in the current dataset. It may excel in specific workloads that no recorded test covers, but the database cannot confirm that.

For users targeting DirectX 12 Ultimate workloads, both cards support the feature set. For compute-heavy tasks, the RTX 4090 Mobile's FP32 throughput of 32.98 TFLOPS versus the RX 7700S's 20.48 TFLOPS gives NVIDIA a clear edge. Interestingly, the RX 7700S has a higher FP16 throughput at 40.96 TFLOPS (2:1 ratio) versus the RTX 4090 Mobile's 32.98 TFLOPS (1:1 ratio), which suggests the AMD card could be competitive in mixed-precision workloads. However, no recorded benchmark in the database tests FP16 performance directly, so this remains an inference from the specification data rather than a measured result.

Architecture Differences

The RTX 4090 Mobile uses the AD103 chip built on NVIDIA's Ada Lovelace architecture. It is manufactured on a 5 nm process at TSMC and packs 45,900 million transistors into a 379 mm² die, yielding a transistor density of 121.1 million per square millimeter. The RX 7700S uses the Navi 33 chip based on AMD's RDNA 3.0 architecture, with the codename "Hotpink Bonefish". It is built on a 6 nm process, also at TSMC, with 13,300 million transistors on a 204 mm² die, for a density of 65.2 million per square millimeter. The NVIDIA chip is more than three times larger in transistor count and nearly double the die area.

The two architectures also differ in compute organization. The RTX 4090 Mobile has 9,728 shading units, 304 TMUs, 112 ROPs, 76 RT cores, and 304 tensor cores. The RX 7700S has 2,048 shading units, 128 TMUs, 64 ROPs, and 32 RT cores, with no tensor cores listed. This structural difference explains the massive compute gap: NVIDIA has roughly 4.75 times the shading units and 2.375 times the RT cores. The absence of tensor cores on the AMD side means no dedicated AI acceleration hardware, while NVIDIA's 304 tensor cores provide a dedicated path for AI and deep learning workloads.

The memory subsystems differ as well. The RTX 4090 Mobile has 16 GB of GDDR6 on a 256-bit bus, delivering 576.0 GB/s. The RX 7700S has 8 GB of GDDR6 on a 128-bit bus, delivering 288.0 GB/s. Both use 18 Gbps effective memory speed, but the wider bus on the NVIDIA card doubles bandwidth. The pixel rate also favors NVIDIA: 189.8 GPixel/s versus 160.0 GPixel/s. The texture rate is 515.3 GTexel/s versus 320.0 GTexel/s.

The RTX 4090 Mobile is part of the GeForce 40 Mobile generation, succeeding the GeForce 30 Mobile line and preceding the GeForce 50 Mobile. The RX 7700S is in the Navi Mobile (RX 7000M) generation, succeeding Polaris Mobile with no recorded successor. Both use the PCIe 4.0 x16 bus interface and support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs are portable device dependent for both.

Specification Differences

The clock speeds differ notably. The RTX 4090 Mobile has a base clock of 1335 MHz and a boost clock of 1695 MHz. The RX 7700S has a base clock of 1500 MHz, a game clock of 2200 MHz, and a boost clock of 2500 MHz. The AMD card runs at higher clocks, but its smaller shader count means it still trails in absolute throughput.

The TDP differs: the RTX 4090 Mobile is rated at 120 W, the RX 7700S at 100 W. Both are integrated GPUs with no power connectors and no suggested PSU. The FP32 compute rating is 32.98 TFLOPS for NVIDIA versus 20.48 TFLOPS for AMD. The FP16 rating is 32.98 TFLOPS (1:1) for NVIDIA versus 40.96 TFLOPS (2:1) for AMD, meaning the AMD card actually has higher peak FP16 throughput despite lower FP32.

The release dates are nearly identical: the RTX 4090 Mobile launched on January 2, 2023, and the RX 7700S launched on January 3, 2023. Both are listed as Active in production status. Neither has a recorded launch MSRP. The RTX 4090 Mobile has a successor (GeForce 50 Mobile), while the RX 7700S does not. The NVIDIA card is in the GeForce 40-series, and the AMD card is in the Radeon RX 7000 series.
