AMD Radeon RX 7600M vs NVIDIA GeForce RTX 4090 Comparison

# Head-to-Head Benchmarks

The benchmark comparison between the AMD Radeon RX 7600M and the NVIDIA GeForce RTX 4090 is starkly one-sided, with the data showing a single shared test result that decisively favors NVIDIA. In the Geekbench OpenCL benchmark, the RTX 4090 scores 255,416 points, while the RX 7600M manages 63,775 points. The delta is a massive -75% from the perspective of the AMD part, meaning the RTX 4090 delivers four times the raw compute performance in this workload. This is not a close contest; the NVIDIA GPU outperforms the AMD mobile chip by a factor that places them in entirely different performance classes.

The RTX 4090’s average benchmark score across its ten recorded tests is 60,347, which sits in the 88th percentile of all GPUs. The RX 7600M, with only one benchmark result, posts an average score of 63,775, placing it in the 89th percentile. Interestingly, the AMD part’s percentile ranking is actually one point higher than the NVIDIA card’s, despite the latter’s overwhelming victory in the head-to-head test. This apparent contradiction stems from the fact that the RTX 4090’s average is dragged down by its PassMark DirectX 9 and DirectX 10 scores of 397 and 224, respectively, which are low compared to its other results.

Looking at the nearest rivals for each card provides additional context. The RX 7600M’s closest competitor is the AMD Radeon RX 9060 XT LP, with an average score of 63,830, putting the RX 7600M just 0.1% behind. It is also nearly identical to the NVIDIA CMP 30HX (63,842, -0.1%) and slightly ahead of the AMD Radeon Pro Vega 56 (63,693, +0.1%). The AMD Radeon Pro WX 9100 sits further ahead at 64,212, a 0.7% gap. For the RTX 4090, the Intel Arc Pro A60 matches its average score almost exactly at 60,326, a delta of 0%. The AMD Radeon Pro Vega 48 is 0.3% ahead, while the AMD Radeon Pro W6600M leads by 2.5%, and the AMD Radeon PRO V710 trails by 2.9%.

The data indicates that the RX 7600M’s single OpenCL score is competitive with its immediate peers, but the RTX 4090’s OpenCL result of 255,416 dwarfs everything in its own rival group. The NVIDIA card’s PassMark G3D score of 38,194 and its GPU compute score of 26,613 further illustrate its compute-heavy design, though these tests were not run on the AMD part.

Architecture Differences

The two GPUs are built on fundamentally different architectures, reflecting their divergent design goals. The AMD Radeon RX 7600M uses the RDNA 3.0 architecture, implemented on the Navi 33 chip with the codename Hotpink Bonefish. It belongs to the Navi Mobile generation within the RX 7000M series. The NVIDIA GeForce RTX 4090, by contrast, uses the Ada Lovelace architecture on the AD102 chip and is part of the GeForce 40-series.

Manufacturing processes differ significantly. The RX 7600M is fabricated on a 6 nm process at TSMC, while the RTX 4090 uses a 5 nm process, also at TSMC. The transistor counts are wildly different: the AMD chip contains 13,300 million transistors on a die size of 204 mm², yielding a transistor density of 65.2M per mm². The NVIDIA chip packs 76,300 million transistors onto a 609 mm² die, achieving a density of 125.3M per mm². The RTX 4090’s die is three times larger and holds nearly six times as many transistors.

Clock speeds also diverge. The RX 7600M has a base clock of 1500 MHz, a boost clock of 2410 MHz, and a game clock of 2070 MHz. Its memory runs at 2000 MHz, effectively 16 Gbps. The RTX 4090 starts at a higher base of 2235 MHz and boosts to 2520 MHz, with memory at 1313 MHz, effectively 21 Gbps. The NVIDIA card does not list a game clock.

Memory configurations are in different leagues. The RX 7600M offers 8 GB of GDDR6 on a 128-bit bus, delivering 256.0 GB/s bandwidth. The RTX 4090 provides 24 GB of GDDR6X on a 384-bit bus, achieving 1.01 TB/s bandwidth. The shader core counts reflect the same disparity: the RX 7600M has 1,792 shading units, 112 TMUs, and 64 ROPs, while the RTX 4090 has 16,384 shading units, 512 TMUs, and 176 ROPs. Ray tracing cores number 28 on the AMD side versus 128 on the NVIDIA side, and the RTX 4090 adds 512 tensor cores, a feature the RX 7600M lacks entirely.

Pixel and texture rates follow suit. The RX 7600M produces 154.2 GPixel/s and 269.9 GTexel/s, while the RTX 4090 achieves 443.5 GPixel/s and 1,290.2 GTexel/s. Compute throughput in FP32 is 17.27 TFLOPS for the AMD card versus 82.58 TFLOPS for the NVIDIA card. FP16 performance is 34.55 TFLOPS (2:1 ratio) for the RX 7600M, while the RTX 4090 matches its FP32 figure at 82.58 TFLOPS (1:1 ratio).

Where Each One Wins

Based strictly on the benchmark data, the RTX 4090 wins every measurable comparison. In the sole head-to-head test, Geekbench OpenCL, it prevails with a score of 255,416 against the RX 7600M’s 63,775, a 75% margin. The NVIDIA card also demonstrates versatility across its suite of tests, posting strong scores in Geekbench Vulkan (271,631), PassMark G3D (38,194), and PassMark GPU Compute (26,613). Its PassMark DirectX scores, while lower in absolute terms, still show capability across older APIs: DirectX 9 at 397, DirectX 11 at 326, DirectX 10 at 224, and DirectX 12 at 150.

The RX 7600M’s only recorded benchmark is the OpenCL test, where its 63,775 score places it in the 89th percentile. This result is competitive with its nearest rivals, as the delta percentages against the RX 9060 XT LP, CMP 30HX, and Pro Vega 56 are all within 0.1%. However, without additional benchmark data, its performance in other workloads cannot be assessed from this fact pack.

For use-case analysis, the RTX 4090’s specifications suggest it is designed for maximum throughput in compute-heavy tasks such as ray tracing, AI inference (given its 512 tensor cores), and high-resolution gaming with large texture sets (24 GB memory). The RX 7600M, with its 90 W TDP and IGP slot width, appears oriented toward power-constrained mobile environments where space and cooling are limited. Its 8 GB memory and 128-bit bus are adequate for mainstream gaming but not for extreme workloads.

The Verdict

The data presents a clear hierarchy. The NVIDIA GeForce RTX 4090 is the dominant performer in every measurable category, with a Geekbench OpenCL score of 255,416 that is four times higher than the RX 7600M’s 63,775. Its architectural advantages—more than five times the shading units, 4.6 times the RT cores, nearly four times the memory bandwidth, and 512 tensor cores—make it the obvious choice for compute-intensive workloads, ray tracing, and high-end gaming. The RTX 4090’s 24 GB of GDDR6X memory and 1.01 TB/s bandwidth support large datasets and high-resolution textures without compromise.

The AMD Radeon RX 7600M, by contrast, is a power-sipping mobile chip with a 90 W TDP and an IGP slot width, designed for portability rather than raw performance. Its single benchmark result places it in the 89th percentile, which is respectable for its class, but it cannot compete with the RTX 4090 on any level. The RX 7600M’s 8 GB memory and 128-bit bus are sufficient for mainstream gaming, and its 17.27 TFLOPS FP32 performance is adequate for typical mobile workloads.

Who should pick which? If the requirement is maximum performance in a desktop workstation or gaming rig, the RTX 4090 is the data-backed choice, despite its end-of-life status and triple-slot footprint. If the requirement is a low-power, integrated mobile solution with competitive performance in its segment, the RX 7600M is the appropriate selection. The 89th percentile ranking of the RX 7600M versus the 88th percentile of the RTX 4090 might confuse some, but the raw benchmark scores settle the matter: the RTX 4090 is in a different performance tier entirely.
