AMD Radeon RX 7600M XT vs NVIDIA N1 16SM Comparison

The Verdict

The AMD Radeon RX 7600M XT and the NVIDIA N1 16SM occupy different positions in the mobile graphics landscape. The RX 7600M XT is a traditional discrete GPU with an established benchmark record, while the N1 16SM is a newer Blackwell IGP design with no recorded benchmark scores in the database. For any workload where measured performance matters, the RX 7600M XT is the only option with data to support a decision. Its average benchmark score of 12710 places it at the 52nd percentile among all GPUs, with nearest rivals including the NVIDIA GeForce GTX 670 (12773, delta -0.5%) and the NVIDIA Tesla K20Xm (12625, delta +0.7%). The N1 16SM sits at the 50th percentile but has an average score of 0, meaning no benchmark results have been recorded. The RX 7600M XT delivers 20.23 TFLOPS FP32 performance versus the N1 16SM's 9.609 TFLOPS, a more than 2x advantage in raw compute throughput. For buyers requiring verified gaming or compute performance today, the RX 7600M XT is the data-backed choice. The N1 16SM remains an unmeasured quantity, and its architecture suggests a different design philosophy rather than a direct competitor.

Architecture Differences

The RX 7600M XT uses the Navi 33 chip built on TSMC's 6 nm process, featuring 13,300 million transistors on a 204 mm² die. This yields a transistor density of 65.2M per mm². The architecture is RDNA 3.0, with the codename Hotpink Bonefish, and it belongs to the Navi Mobile (RX 7000M) generation. It was released on 2023-01-03 and remains in active production.

The N1 16SM uses the GB20B chip built on TSMC's 5 nm process, with a die size of 382 mm². Transistor count is listed as unknown. The architecture is Blackwell 2.0, belonging to the Blackwell IGP (N1x) generation, with a release date of 2026-05-31. It is also in active production.

Memory configurations differ substantially. The RX 7600M XT uses 8 GB of GDDR6 on a 128-bit bus, with memory clocked at 2250 MHz (18 Gbps effective) for 288.0 GB/s bandwidth. The N1 16SM uses 128 GB of LPDDR5X on a 256-bit bus, with memory at 1067 MHz (8.5 Gbps effective) for 273.2 GB/s bandwidth. The N1 16SM has 16 times the memory capacity but slightly lower bandwidth.

Compute resources show a mixed picture. Both GPUs have 2048 shading units and 128 texture mapping units. The RX 7600M XT has 64 ROPs versus 24 on the N1 16SM, giving it a 158.0 GPixel/s pixel rate versus 56.30 GPixel/s. Texture rates are closer: 316.0 GTexel/s versus 300.3 GTexel/s. The RX 7600M XT has 32 ray tracing cores, while the N1 16SM has 16 RT cores but adds 64 tensor cores (the RX 7600M XT has none listed).

FP32 throughput strongly favors the RX 7600M XT at 20.23 TFLOPS versus 9.609 TFLOPS. FP16 performance is 40.45 TFLOPS (2:1 ratio) on the RX 7600M XT, while the N1 16SM delivers 9.609 TFLOPS at a 1:1 ratio. The RX 7600M XT supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1 16SM lists its API support as N/A for DirectX, OpenGL, and Vulkan.

Power characteristics also differ. The RX 7600M XT has a TDP of 120 W and no power connectors, as it is an IGP form factor. The N1 16SM has unknown TDP, also an IGP form factor with no power connectors. Both use PCIe interfaces: the RX 7600M XT uses PCIe 4.0 x16, while the N1 16SM uses PCIe 5.0 x16.

Where Each One Wins

The RX 7600M XT wins decisively in every measurable category. Its FP32 compute of 20.23 TFLOPS more than doubles the N1 16SM's 9.609 TFLOPS, making it the clear choice for general-purpose GPU compute workloads. The pixel rate of 158.0 GPixel/s versus 56.30 GPixel/s indicates a strong advantage in rasterization-heavy tasks. The texture rate of 316.0 GTexel/s slightly edges out 300.3 GTexel/s, suggesting comparable texturing throughput. The RX 7600M XT's 8 GB GDDR6 memory, while smaller in capacity, delivers 288.0 GB/s bandwidth versus 273.2 GB/s, so it also wins on memory throughput.

The N1 16SM wins on memory capacity with 128 GB of LPDDR5X versus 8 GB of GDDR6. This is a 16x capacity advantage, which could matter for very large datasets or certain AI inference workloads that require holding substantial data in memory. The N1 16SM also has 64 tensor cores versus none on the RX 7600M XT, giving it a structural advantage for tensor-based operations, though no benchmark data confirms the magnitude of this advantage. The Blackwell 2.0 architecture on a 5 nm process node represents a newer process generation, which may offer efficiency improvements, though TDP for the N1 16SM is unknown.

The RX 7600M XT's API support (DirectX 12 Ultimate, OpenGL 4.6, Vulkan 1.4) versus N/A listings for the N1 16SM means the AMD part is immediately usable in standard graphics and compute stacks. The N1 16SM's API status is unverified in the database.

The nearest rivals to the RX 7600M XT in the database provide context. The NVIDIA GeForce GTX 670 has an average score of 12773, only 0.5% higher. The NVIDIA Tesla K20Xm scores 12625, which is 0.7% lower. The NVIDIA GeForce GTX 590 scores 12830, 0.9% higher, and the AMD Radeon Pro 455 scores 12831, also 0.9% higher. The RX 7600M XT sits effectively at parity with these older discrete GPUs despite being a mobile part from a newer generation.

Because the N1 16SM has zero recorded benchmarks and an average score of 0, no direct comparison of measured performance is possible. The architectural data, however, shows the RX 7600M XT with a 2.1x FP32 advantage, a 2.8x pixel rate advantage, and a slight texture rate advantage. The N1 16SM counters with 16x the memory capacity and a tensor core presence. The RX 7600M XT also has a documented API support set (DirectX 12 Ultimate, OpenGL 4.6, Vulkan 1.4), whereas the N1 16SM's API compatibility is listed as N/A in the database.

The RX 7600M XT's clock behavior shows a base of 1280 MHz, a game clock of 2023 MHz, and a boost of 2469 MHz. The N1 16SM has a base of 741 MHz and a boost of 2346 MHz, with no game clock listed. The memory clocks differ: 2250 MHz (18 Gbps effective) for the RX 7600M XT versus 1067 MHz (8.5 Gbps effective) for the N1 16SM.

The production status for both parts is Active, and both are IGP form factors with no power connectors. The RX 7600M XT was released in early 2023, while the N1 16SM is dated to mid-2026. The RX 7600M XT's predecessor is listed as Polaris Mobile, while the N1 16SM has no predecessor listed. Neither part has a successor listed in the database.

The data positions the RX 7600M XT as a measured, competitive mobile GPU with performance near the GTX 670 and GTX 590 class. The N1 16SM is an unverified newcomer whose specifications suggest a memory-heavy, tensor-capable design rather than a rasterization-focused one. Until benchmark results are recorded, any performance conclusions about the N1 16SM remain speculative, and the RX 7600M XT stands as the only part with actionable performance data.
