AMD Radeon RX 7600M vs NVIDIA GeForce RTX 4080 Comparison

The AMD Radeon RX 7600M and the NVIDIA GeForce RTX 4080 occupy opposite ends of the mobile and desktop GPU spectrum, but the database records them as direct competitors by average score. The RX 7600M is a slim, low-power integrated graphics package for laptops, while the RTX 4080 is a massive, triple-slot desktop board with a 16-pin connector. The benchmark data shows a single clear winner in raw compute, but the architectural split explains why these parts exist for entirely different use cases.

Where Each One Wins

The NVIDIA GeForce RTX 4080 wins the only direct head-to-head benchmark recorded in the database, the Geekbench OpenCL test, with a score of 214739 against the AMD Radeon RX 7600M's 63775. That is a 70.3% deficit for the AMD part, a massive gap that reflects the fundamental difference in silicon size, power envelope, and memory subsystem. Every measurable compute workload in the database favors the RTX 4080 by a wide margin, and there are no recorded tests where the RX 7600M takes the lead.

However, the RX 7600M wins in the context of its intended platform: it is an integrated graphics processor (IGP) with no power connectors and a 90 W TDP, designed for portable devices where the display outputs are "Portable Device Dependent." The RTX 4080, by contrast, is a triple-slot card that requires a 700 W suggested power supply and measures 310 mm in length, 140 mm in height, and 61 mm in width. If the use case is a thin-and-light laptop, the RX 7600M is the only viable option of the two; if the use case is a desktop workstation or gaming rig with space and power to spare, the RTX 4080 is the only one that physically fits. The data shows no overlap in practical deployment scenarios, so the "win" depends entirely on the chassis, not the benchmark score.

Architecture Differences

The two GPUs come from different manufacturers, different process nodes, and different design philosophies. The AMD Radeon RX 7600M uses the Navi 33 chip built on RDNA 3.0 architecture, fabricated by TSMC on a 6 nm process. The chip contains 13,300 million transistors on a 204 mm² die, yielding a transistor density of 65.2 million per square millimeter. The NVIDIA GeForce RTX 4080 uses the AD103 chip built on Ada Lovelace architecture, also fabricated by TSMC but on a 5 nm process. That die is far larger at 379 mm² and packs 45,900 million transistors, for a density of 121.1 million per square millimeter.

The memory configurations diverge sharply. The RX 7600M has 8 GB of GDDR6 on a 128-bit bus, delivering 256.0 GB/s of bandwidth. The RTX 4080 has 16 GB of GDDR6X on a 256-bit bus, delivering 716.8 GB/s, nearly three times the bandwidth. The RTX 4080 also has a much larger execution engine: 9728 shading units, 304 texture mapping units, 112 render output units, 76 ray tracing cores, and 304 tensor cores. The RX 7600M has 1792 shading units, 112 TMUs, 64 ROPs, and 28 ray tracing cores, with no tensor cores listed. Clock speeds favor the NVIDIA part as well: the RTX 4080 boosts to 2505 MHz versus 2410 MHz for the RX 7600M, and its base clock is 2205 MHz versus 1500 MHz.

The compute throughput reflects the hardware disparity. The RTX 4080 reaches 48.74 TFLOPS for both FP32 and FP16 (1:1 ratio), while the RX 7600M delivers 17.27 TFLOPS FP32 and 34.55 TFLOPS FP16 (2:1 ratio). Pixel rate and texture rate also favor the RTX 4080: 280.6 GPixel/s and 761.5 GTexel/s versus 154.2 GPixel/s and 269.9 GTexel/s. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, but the RTX 4080 adds tensor cores for AI workloads that the AMD part lacks entirely.

Head-to-Head Benchmarks

The database records exactly one head-to-head test between these two GPUs: Geekbench OpenCL. The NVIDIA GeForce RTX 4080 scores 214739, while the AMD Radeon RX 7600M scores 63775. The delta is -70.3% for the AMD part, meaning the RTX 4080 is roughly 3.4 times faster in this compute workload. That is not a marginal difference; it is a category-level gap. For context, the RX 7600M's nearest rivals in the database are the AMD Radeon RX 9060 XT LP at 63830 (delta -0.1%), the NVIDIA CMP 30HX at 63842 (delta -0.1%), and the AMD Radeon Pro Vega 56 at 63693 (delta 0.1%). The RTX 4080's nearest rivals include the NVIDIA GeForce RTX 4080 SUPER at 54209 (delta 0.1%), the AMD Radeon Pro W5700X at 54828 (delta -1.1%), and the AMD Radeon RX 6750 GRE 12 GB at 55698 (delta -2.6%).

The RTX 4080 also has a broader benchmark profile in the database, with results for 3DMark Steel Nomad DX12 (6567), Geekbench Vulkan (263779), and multiple Passmark tests. Its Passmark G3D score is 34457, and its Passmark GPU Compute score is 20671. The RX 7600M has only the single Geekbench OpenCL result, which places it at the 89th percentile of all GPUs, while the RTX 4080 sits at the 86th percentile despite its higher raw scores. That percentile discrepancy reflects the fact that the RTX 4080's average benchmark score of 54247 is pulled down by its lower Passmark DirectX scores (204 for DX10, 314 for DX11, 132 for DX12, 370 for DX9) and a Passmark G2D score of 1239. The RX 7600M's average score equals its single OpenCL score of 63775, so the percentile comparison is not directly meaningful across different test suites.

FAQ

Q: Which GPU has higher raw compute performance?

A: The NVIDIA GeForce RTX 4080 dominates the only shared benchmark, Geekbench OpenCL, with a score of 214739 versus 63775 for the AMD Radeon RX 7600M, a -70.3% delta for the AMD part. The RTX 4080 also has far higher FP32 throughput at 48.74 TFLOPS versus 17.27 TFLOPS.

Q: Why would anyone choose the AMD Radeon RX 7600M?

A: The RX 7600M is an integrated graphics processor with a 90 W TDP, no power connectors, and portable-device-dependent display outputs. It is designed for laptops and compact systems where a triple-slot, 320 W card like the RTX 4080 cannot fit or be powered.

Q: How do the memory systems compare?

A: The RX 7600M has 8 GB of GDDR6 on a 128-bit bus with 256.0 GB/s bandwidth. The RTX 4080 has 16 GB of GDDR6X on a 256-bit bus with 716.8 GB/s bandwidth, which is 2.8 times the bandwidth of the AMD part.

Q: What are the physical requirements for the RTX 4080?

A: The RTX 4080 is a triple-slot card measuring 310 mm by 140 mm by 61 mm, requiring a 16-pin power connector and a suggested 700 W power supply. The RX 7600M is an IGP with no slot width, no power connectors, and no suggested PSU.

Q: Do both GPUs support the same graphics APIs?

A: Yes, both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX 4080 additionally includes 304 tensor cores, while the RX 7600M has none listed.

Q: Which GPU has a higher percentile ranking?

A: The RX 7600M ranks at the 89th percentile of all GPUs, while the RTX 4080 ranks at the 86th percentile. The RTX 4080's average benchmark score of 54247 is lower than its single OpenCL score due to weaker Passmark sub-tests.

The Verdict

The data points to a simple conclusion: these are not competing products in any practical sense. The NVIDIA GeForce RTX 4080 is a high-end desktop GPU with 16 GB of GDDR6X, 9728 shading units, 76 ray tracing cores, and 304 tensor cores, built for maximum compute and rendering throughput. The AMD Radeon RX 7600M is a 90 W integrated solution with 8 GB of GDDR6 and 1792 shading units, built for portability and low power draw. The benchmark gap is enormous: the RTX 4080 scores 214739 in OpenCL versus 63775 for the RX 7600M, a 70.3% deficit that no driver or optimization could realistically close.

For a desktop builder with a 700 W power supply and a triple-slot chassis, the RTX 4080 is the obvious choice based on the recorded scores. Its nearest rivals in the database, such as the RTX 4080 SUPER at a 0.1% delta, confirm it sits at the top of its performance tier. For a laptop OEM or a user targeting a slim, fanless, or low-power system, the RX 7600M is the only option that fits the physical constraints, and its 89th percentile ranking shows it performs well within its class. The verdict is not about which GPU is "better" in a vacuum; it is about which platform the user is building. The RTX 4080 is end-of-life and has a successor in the GeForce 50 series, while the RX 7600M is still active, so availability may also factor into the decision.
