AMD Radeon RX 7600M vs AMD Radeon RX 7900M Comparison

Head-to-Head Benchmarks

The database contains one directly comparable benchmark run for these two mobile GPUs: Geekbench OpenCL. In that test, the AMD Radeon RX 7900M scores 129,499 points, while the AMD Radeon RX 7600M scores 63,775 points. The RX 7900M leads by 103.1%, meaning it more than doubles the RX 7600M's raw compute output in this workload. That is a massive gap, and it aligns with the overall positioning of the two parts.

Looking at the 3DMark Steel Nomad DX12 result, the RX 7900M posts 4,201 points. The RX 7600M has no recorded result in this test, so direct comparison is limited to the OpenCL score alone. However, the RX 7900M also shows a Geekbench Vulkan score of 158,760, which is not matched by any RX 7600M entry in the database. For the single shared benchmark, the RX 7900M is the clear winner.

The average benchmark scores tell the same story. The RX 7900M averages 97,487 across all recorded tests, while the RX 7600M averages 63,775. That puts the RX 7900M roughly 53% higher on average, though the exact delta varies by workload. The RX 7900M sits at the 94th percentile among all GPUs in the database, while the RX 7600M sits at the 89th percentile. Both are strong performers, but the RX 7900M is in a different tier entirely.

The RX 7900M's nearest rivals are professional and workstation cards. It is 0.4% ahead of the AMD Radeon Pro VII, 4.3% behind the NVIDIA Quadro RTX 6000, 5.4% ahead of the AMD Radeon Instinct MI60, and 6.3% ahead of the NVIDIA RTX A4500. That places it in the upper echelon of the database's mobile and prosumer GPU rankings.

The RX 7600M, by contrast, competes with lower-tier cards. It is 0.1% behind the AMD Radeon RX 9060 XT LP, 0.1% behind the NVIDIA CMP 30HX, 0.1% ahead of the AMD Radeon Pro Vega 56, and 0.7% behind the AMD Radeon Pro WX 9100. These are tight margins, indicating the RX 7600M is right at the boundary between mid-range and high-end performance in the database's scoring system.

Where Each One Wins

The RX 7900M wins the only head-to-head benchmark, and it wins by a landslide. In Geekbench OpenCL, it delivers 103.1% more performance than the RX 7600M. That is not a marginal advantage; it is a generational gap in raw compute throughput. The RX 7900M also has recorded Vulkan and 3DMark results, while the RX 7600M does not, which suggests the RX 7900M is more frequently tested in demanding workloads.

For users prioritizing maximum frame rates in heavy 3D applications, the RX 7900M is the obvious choice. Its 3DMark Steel Nomad score of 4,201 indicates strong DX12 rasterization performance. The Vulkan score of 158,760 also points to solid low-level API efficiency. These are workloads where the RX 7600M simply has no recorded data, and based on the OpenCL gap, it would likely trail significantly.

The RX 7600M is not a weak card, though. Its percentile rank of 89 places it above the majority of GPUs in the database. It sits within 1% of several established cards, including the RX 9060 XT LP, CMP 30HX, Radeon Pro Vega 56, and Radeon Pro WX 9100. That makes it a reasonable choice for 1080p gaming or lighter compute tasks where the extra power and size of the RX 7900M are not necessary.

The RX 7900M, meanwhile, holds a 94th percentile rank, putting it in the top 6% of all GPUs. Its nearest rivals are all prosumer or workstation parts, which tells you the target audience: users who need serious compute throughput, not just casual gaming. The RX 7900M's 16 GB memory capacity and 256-bit bus give it a substantial bandwidth advantage, though the RX 7600M's 8 GB and 128-bit bus are adequate for less demanding scenarios.

The Verdict

The data is unambiguous. The AMD Radeon RX 7900M is the faster GPU by every measurable metric in the database. In the sole head-to-head benchmark, it outperforms the RX 7600M by 103.1%. Its average benchmark score is 97,487 versus 63,775, a difference of roughly 53%. Its percentile rank is 94 versus 89, and it has successful runs in 3DMark and Vulkan tests where the RX 7600M has no recorded results.

Choose the RX 7900M if you need top-tier mobile graphics performance, especially for compute-heavy workloads like rendering, simulation, or high-resolution gaming. Its 16 GB of memory and 576.0 GB/s of bandwidth are class-leading for a mobile part. Its 180 W TDP is high, but the performance return is proportionate. The RX 7600M is for users who need solid 1080p performance without the power draw or cost of a flagship. Its 8 GB memory and 256.0 GB/s bandwidth are sufficient for mainstream gaming, and its 90 W TDP makes it far easier to cool in thin laptops.

There is no scenario in the recorded data where the RX 7600M beats the RX 7900M. If the choice is purely performance-driven, the RX 7900M wins outright. If power efficiency or physical size is the constraint, the RX 7600M may be the practical pick, but it will deliver less than half the compute performance in the one benchmark they share.

Architecture Differences

Both GPUs use the RDNA 3.0 architecture from AMD's Radeon RX 7000 series, but they are built on different chips and processes. The RX 7900M uses the Navi 31 chip with the codename Plum Bonito, fabricated on TSMC's 5 nm process. The RX 7600M uses the Navi 33 chip with the codename Hotpink Bonefish, fabricated on TSMC's 6 nm process. The 5 nm node gives the RX 7900M a transistor density advantage: 109.1 million transistors per square millimeter versus 65.2 million for the RX 7600M.

The chip sizes differ dramatically. The RX 7900M's Navi 31 die measures 529 mm² and contains 57,700 million transistors. The RX 7600M's Navi 33 die measures 204 mm² and contains 13,300 million transistors. That is a 4.3x difference in transistor count and a 2.6x difference in die area. The RX 7900M is fundamentally a much larger, more complex chip.

Compute resources scale accordingly. The RX 7900M has 4,608 shading units, 288 texture mapping units, 192 ROPs, and 72 ray tracing cores. The RX 7600M has 1,792 shading units, 112 TMUs, 64 ROPs, and 28 RT cores. The RX 7900M has roughly 2.6x the shading units, 2.6x the TMUs, 3x the ROPs, and 2.6x the RT cores. Neither card has tensor cores listed.

Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both use PCIe 4.0 x16 interfaces and are marked as integrated graphics packages (IGP) with portable-device-dependent display outputs. The architectural gap is purely in scale, not in feature set.

Specification Differences

The clock speeds are interesting. The RX 7900M has a lower boost clock at 2090 MHz, compared to the RX 7600M's 2410 MHz. The RX 7600M also lists a game clock of 2070 MHz, while the RX 7900M does not have a recorded game clock. However, the RX 7900M's base clock is higher at 1825 MHz versus 1500 MHz. The memory clocks also differ: the RX 7900M runs at 2250 MHz (18 Gbps effective), while the RX 7600M runs at 2000 MHz (16 Gbps effective).

The RX 7900M's memory subsystem is far larger. It has 16 GB of GDDR6 on a 256-bit bus, delivering 576.0 GB/s. The RX 7600M has 8 GB on a 128-bit bus, delivering 256.0 GB/s. That is a 2.25x bandwidth advantage for the RX 7900M.

Power consumption is another major split. The RX 7900M has a TDP of 180 W, while the RX 7600M has a TDP of 90 W. Both are listed as IGP slot width with no power connectors, meaning they are soldered or integrated into the motherboard. Neither has a suggested PSU rating.

Performance rates reflect the hardware. The RX 7900M achieves 401.3 GPixel/s pixel rate and 601.9 GTexel/s texture rate, with 38.52 TFLOPS FP32 and 77.05 TFLOPS FP16 (2:1). The RX 7600M achieves 154.2 GPixel/s and 269.9 GTexel/s, with 17.27 TFLOPS FP32 and 34.55 TFLOPS FP16 (2:1). The RX 7900M is roughly 2.2x to 2.6x faster in these throughput metrics.

Release dates differ by about nine months. The RX 7600M launched on January 3, 2023, while the RX 7900M launched on October 18, 2023. Both are still in active production, and both have the same predecessor, Polaris Mobile. Neither has a listed successor or launch MSRP in the database.
