AMD Radeon RX 7600M vs NVIDIA GeForce RTX 4090 Mobile Comparison

Head-to-Head Benchmarks

The benchmark data presents a decisive outcome: the NVIDIA GeForce RTX 4090 Mobile wins the only recorded head-to-head test, the Geekbench OpenCL benchmark, by a commanding margin. The AMD Radeon RX 7600M scores 63,775, while the NVIDIA GeForce RTX 4090 Mobile scores 180,831. This translates to a delta of -64.7% for the AMD part, meaning the NVIDIA GPU delivers roughly 2.8 times the raw compute performance in this OpenCL workload. There are no recorded wins for the AMD Radeon RX 7600M in the head-to-head comparison, and exactly one win for the NVIDIA GeForce RTX 4090 Mobile.

The magnitude of this OpenCL gap is consistent with the broader compute specifications recorded in the database. The NVIDIA part is rated at 32.98 TFLOPS for FP32, while the AMD part is rated at 17.27 TFLOPS. That is a substantial raw throughput difference, and the benchmark result reflects it directly. In the Geekbench OpenCL test, the NVIDIA GPU nearly triples the AMD GPU's score, which is a far larger proportional difference than the FP32 rating alone would suggest. This indicates that the NVIDIA part is not just faster in theory, but also scales better in the actual compute workload measured.

Looking at the database's percentile rankings, the AMD Radeon RX 7600M sits at the 89th percentile among all GPUs, while the NVIDIA GeForce RTX 4090 Mobile sits at the 84th percentile. This is a curious inversion: the AMD part has a higher percentile ranking despite losing the head-to-head benchmark. The explanation lies in the average benchmark score metric. The AMD part has a single recorded benchmark score of 63,775, which is also its average. The NVIDIA part has multiple recorded benchmark scores, including a Passmark G3D score of 27,212 and a Passmark GPU Compute score of 12,347, and its average across all recorded tests is 43,667. The AMD part's average score is therefore higher than the NVIDIA part's average score, even though the NVIDIA part wins the specific OpenCL head-to-head test. This is a case where a single strong result can inflate an average, while a suite of diverse tests can pull an average down.

The nearest rivals in the database for the AMD part include the AMD Radeon RX 9060 XT LP with an average score of 63,830 and a delta of -0.1%, and the NVIDIA CMP 30HX with an average score of 63,842 and a delta of -0.1%. The AMD Radeon Pro Vega 56 (63,693, +0.1%) and the AMD Radeon Pro WX 9100 (64,212, -0.7%) are also nearby. For the NVIDIA part, the nearest rivals are the NVIDIA Quadro M6000 (43,301, +0.8%), the NVIDIA GeForce RTX 5050 Mobile (43,268, +0.9%), the NVIDIA Quadro M6000 24 GB (43,262, +0.9%), and the NVIDIA RTX A6000 (44,075, -0.9%). These rival relationships show that the AMD part is clustered with high-end workstation and mid-range desktop cards in terms of average score, while the NVIDIA part is clustered with older Quadro professional cards and a newer mobile GeForce part.

The Verdict

The data points to a clear choice for anyone prioritizing raw compute performance: the NVIDIA GeForce RTX 4090 Mobile. In the only direct head-to-head benchmark recorded, it beats the AMD Radeon RX 7600M by 64.7%, which is an overwhelming advantage. The NVIDIA part also has a significantly higher FP32 rating at 32.98 TFLOPS versus 17.27 TFLOPS, and its memory bandwidth of 576.0 GB/s is more than double the AMD part's 256.0 GB/s. For workloads that depend on massive parallel throughput, such as large-scale compute tasks or heavy graphics rendering, the NVIDIA GPU is the obvious selection based on the recorded measurements.

However, the database's percentile rankings tell a more nuanced story. The AMD Radeon RX 7600M holds the 89th percentile among all GPUs, while the NVIDIA GeForce RTX 4090 Mobile holds the 84th percentile. This is driven by the AMD part's average benchmark score of 63,775, which exceeds the NVIDIA part's average of 43,667. If a user is comparing overall database standing rather than a single workload, the AMD part appears stronger. But this is an artifact of the limited test suite: the AMD part has only one recorded benchmark, while the NVIDIA part has nine. The NVIDIA part's average is diluted by its low Passmark scores in DirectX 9 (310), DirectX 10 (173), and DirectX 11 (262), which are legacy API tests that likely do not reflect modern gaming or compute performance. The AMD part has no such legacy scores recorded, so its average is artificially high.

For a user who values consistency across a broad spectrum of tests, the NVIDIA part's diverse benchmark record (including a strong Passmark G3D score of 27,212 and a Passmark GPU Compute score of 12,347) suggests it is a more versatile performer. The AMD part's single OpenCL score, while respectable, does not provide evidence of strength in other API workloads. The verdict is therefore straightforward: the NVIDIA GeForce RTX 4090 Mobile wins on the head-to-head benchmark and on raw compute specifications, making it the preferred choice for performance-critical applications. The AMD part's higher percentile is a statistical quirk of an incomplete benchmark record, not a genuine performance advantage.

Architecture Differences

The two GPUs are built on fundamentally different architectures. The AMD Radeon RX 7600M uses the RDNA 3.0 architecture, with a chip codenamed Hotpink Bonefish and the Navi 33 die. It belongs to the Navi Mobile generation within the Radeon RX 7000 series. The NVIDIA GeForce RTX 4090 Mobile uses the Ada Lovelace architecture, with the AD103 chip, and belongs to the GeForce 40 Mobile generation. These are separate design philosophies from AMD and NVIDIA respectively.

The process nodes differ: the AMD part is fabricated on a 6 nm process, while the NVIDIA part is fabricated on a 5 nm process, both from TSMC. This gives the NVIDIA chip a density advantage, with a transistor density of 121.1M per mm² compared to the AMD part's 65.2M per mm². The NVIDIA chip also has far more transistors overall: 45,900 million versus 13,300 million. The die sizes reflect this: the NVIDIA AD103 measures 379 mm², while the AMD Navi 33 measures 204 mm². The NVIDIA chip is physically larger and packs more than three times the transistors.

The compute architectures diverge significantly. The AMD part has 1,792 shading units, 112 texture mapping units, and 64 render output units. It also has 28 ray tracing cores and no tensor cores. The NVIDIA part has 9,728 shading units, 304 texture mapping units, and 112 render output units. It has 76 ray tracing cores and 304 tensor cores. The presence of tensor cores on the NVIDIA part is a major architectural difference, as these are specialized hardware for AI and deep learning workloads that the AMD part lacks entirely.

The memory subsystems are also architecturally distinct. The AMD part uses 8 GB of GDDR6 memory on a 128-bit bus, yielding 256.0 GB/s of bandwidth. The NVIDIA part uses 16 GB of GDDR6 memory on a 256-bit bus, yielding 576.0 GB/s of bandwidth. The NVIDIA part has twice the memory capacity and more than double the bandwidth. Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, and both use a PCIe 4.0 x16 bus interface. The AMD part's FP16 performance is rated at 34.55 TFLOPS (2:1 ratio relative to FP32), while the NVIDIA part's FP16 is rated at 32.98 TFLOPS (1:1 ratio). This means the AMD part has a theoretical advantage in FP16 throughput, but the NVIDIA part maintains its FP32 rate in FP16, which is a different architectural approach.

Specification Differences

The two parts differ across nearly every recorded specification. The AMD Radeon RX 7600M has a base clock of 1500 MHz and a boost clock of 2410 MHz, with a game clock of 2070 MHz. The NVIDIA GeForce RTX 4090 Mobile has a base clock of 1335 MHz and a boost clock of 1695 MHz, with no recorded game clock. Despite the AMD part having higher clock speeds, the NVIDIA part wins on performance due to its vastly larger core count.

Memory specifications diverge sharply: the AMD part has 8 GB of GDDR6 on a 128-bit bus with 256.0 GB/s bandwidth, while the NVIDIA part has 16 GB of GDDR6 on a 256-bit bus with 576.0 GB/s bandwidth. The memory clock also differs: the AMD part runs at 2000 MHz with 16 Gbps effective, while the NVIDIA part runs at 2250 MHz with 18 Gbps effective.

The compute units scale differently: the AMD part has 1,792 shading units, 112 TMUs, 64 ROPs, 28 RT cores, and no tensor cores. The NVIDIA part has 9,728 shading units, 304 TMUs, 112 ROPs, 76 RT cores, and 304 tensor cores. The pixel rate for the AMD part is 154.2 GPixel/s, while the NVIDIA part achieves 189.8 GPixel/s. The texture rate for the AMD part is 269.9 GTexel/s, while the NVIDIA part achieves 515.3 GTexel/s. FP32 performance is 17.27 TFLOPS for the AMD part and 32.98 TFLOPS for the NVIDIA part.

Power consumption differs as well: the AMD part is rated at 90 W TDP, while the NVIDIA part is rated at 120 W TDP. Both are IGP slot width with no power connectors and portable device dependent display outputs. The AMD part was released on 2023-01-03, one day after the NVIDIA part's release on 2023-01-02. The AMD part's predecessor is Polaris Mobile, while the NVIDIA part's predecessor is GeForce 30 Mobile and its successor is GeForce 50 Mobile. Neither part has a recorded launch MSRP.

The presence of 304 tensor cores gives it a hardware advantage for AI and machine learning tasks that the AMD part cannot match.

The AMD Radeon RX 7600M wins on the percentile ranking, sitting at the 89th percentile versus the NVIDIA part's 84th. This is driven by its higher average benchmark score of 63,775, which exceeds the NVIDIA part's average of 43,667. The AMD part also has higher clock speeds: a base clock of 1500 MHz versus 1335 MHz, a boost clock of 2410 MHz versus 1695 MHz, and a game clock of 2070 MHz that the NVIDIA part does not record. Its FP16 rating of 34.55 TFLOPS (2:1) exceeds the NVIDIA part's 32.98 TFLOPS (1:1), giving it a theoretical edge in FP16 workloads. The AMD part also consumes less power at 90 W TDP versus 120 W TDP.

The use-case split is clear. For users who need maximum compute throughput, high memory bandwidth, tensor core acceleration, or large VRAM capacity, the NVIDIA GeForce RTX 4090 Mobile is the superior choice based on the data. For users who prioritize a higher database percentile ranking, lower power consumption, higher clock speeds, or FP16 throughput, the AMD Radeon RX 7600M has specific advantages. However, the single head-to-head benchmark result, which shows a 64.7% deficit for the AMD part, is the most direct evidence of real-world performance differences. The NVIDIA part is the performance leader, while the AMD part offers a lower-power alternative with a better percentile standing in the database's aggregate statistics.
