AMD Radeon RX 7600M vs NVIDIA N1 20SM Comparison

The Verdict

The recorded data presents a clear but incomplete picture. The AMD Radeon RX 7600M is a fully benchmarked mobile GPU with a single OpenCL score of 63775, placing it in the 89th percentile of all GPUs in the database. The NVIDIA N1 20SM, by contrast, has no benchmark entries, no average score, and sits at the 50th percentile, making direct performance comparison impossible from the available measurements.

For users who need verified compute performance today, the Radeon RX 7600M is the only option with recorded data. Its nearest rivals include the AMD Radeon RX 9060 XT LP at 63830 (0.1% faster), the NVIDIA CMP 30HX at 63842 (0.1% faster), and the AMD Radeon Pro WX 9100 at 64212 (0.7% faster). The RX 7600M trails these by fractions of a percent, indicating it sits squarely in a well-populated performance tier. The NVIDIA N1 20SM cannot be placed in any performance bracket because the database contains no scores for it.

The choice between these two parts depends entirely on whether the user prioritizes verified data or architectural features. The RX 7600M delivers confirmed compute results with a 90 W TDP and a 6 nm process. The N1 20SM offers a larger die, a newer architecture, and substantially more memory, but no measured performance. The data favors the RX 7600M for immediate deployment, while the N1 20SM remains an unknown quantity until benchmark results appear.

Architecture Differences

The two GPUs diverge fundamentally in design philosophy. The AMD Radeon RX 7600M uses the Navi 33 chip built on RDNA 3.0 architecture, codenamed Hotpink Bonefish, from the Navi Mobile (RX 7000M) generation. It is manufactured by TSMC on a 6 nm process with 13,300 million transistors on a 204 mm² die, yielding a transistor density of 65.2 million per square millimeter. The NVIDIA N1 20SM uses the GB20B chip on Blackwell 2.0 architecture from the Blackwell IGP (N1x) generation, also fabricated by TSMC but on a 5 nm process. Its transistor count is listed as unknown, though its die size measures 382 mm², which is 178 mm² larger than the AMD chip.

The compute layouts differ significantly. The RX 7600M contains 1792 shading units, 112 texture mapping units, 64 render output units, and 28 ray tracing cores. The N1 20SM carries 2560 shading units, 160 TMUs, but only 24 ROPs, along with 20 ray tracing cores and 80 tensor cores. The AMD part has no tensor cores listed, while the NVIDIA part includes them. The shading unit advantage favors NVIDIA by 768 units, and the TMU advantage favors NVIDIA by 48 units, but the ROP count favors AMD by 40 units.

Clock speeds show a different balance. The RX 7600M has a base clock of 1500 MHz and a boost clock of 2410 MHz, with a game clock of 2070 MHz. The N1 20SM starts lower at 741 MHz base but boosts to 2346 MHz. Memory clocks also differ: AMD runs at 2000 MHz with 16 Gbps effective, while NVIDIA runs at 1067 MHz with 8.5 Gbps effective. The AMD memory clock is nearly double the NVIDIA value.

Memory capacity and type present the starkest contrast. The RX 7600M has 8 GB of GDDR6 on a 128-bit bus, delivering 256.0 GB/s bandwidth. The N1 20SM has 128 GB of LPDDR5X on a 256-bit bus, delivering 273.2 GB/s bandwidth. The NVIDIA part offers 16 times the memory capacity and slightly higher bandwidth, despite the lower memory clock. The bus width doubles from 128 to 256 bits.

The process node difference is minimal but present: 6 nm for AMD versus 5 nm for NVIDIA. Both parts are classified as IGP (integrated graphics processor) slot width with no power connectors. The AMD TDP is listed as 90 W, while the NVIDIA TDP is unknown. The bus interfaces differ, with AMD using PCIe 4.0 x16 and NVIDIA using PCIe 5.0 x16. Display outputs are portable device dependent for AMD, while NVIDIA lists a single HDMI output.

API support separates the two fundamentally. The RX 7600M supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1 20SM lists N/A for DirectX, OpenGL, and Vulkan, indicating no conventional graphics API compatibility in the recorded data. This suggests the NVIDIA part may be intended for specialized compute workloads rather than general graphics rendering. The RX 7600M also has a predecessor listed as Polaris Mobile, while the N1 20SM has no predecessor or successor recorded.

Where Each One Wins

The RX 7600M wins in every measured category because the database contains no benchmark results for the N1 20SM. The single recorded score of 63775 in Geekbench OpenCL gives AMD the only verified performance data point. The winsA field in the head-to-head benchmarks is zero, and winsB is zero, reflecting the absence of paired tests.

For compute workloads, the RX 7600M delivers 17.27 TFLOPS FP32 and 34.55 TFLOPS FP16 with a 2:1 ratio. The N1 20SM delivers 12.01 TFLOPS FP32 and 12.01 TFLOPS FP16 with a 1:1 ratio. The AMD part is 43.8% ahead in FP32 and 187.7% ahead in FP16 throughput. The pixel rates favor AMD at 154.2 GPixel/s versus 56.30 GPixel/s for NVIDIA. The texture rates favor NVIDIA at 375.4 GTexel/s versus 269.9 GTexel/s for AMD.

Memory capacity clearly favors NVIDIA with 128 GB versus 8 GB, and bandwidth favors NVIDIA marginally at 273.2 GB/s versus 256.0 GB/s. The NVIDIA part also has the tensor core advantage with 80 tensor cores, which the AMD part lacks entirely. The die size advantage belongs to NVIDIA at 382 mm² versus 204 mm², though the transistor count is unknown for NVIDIA.

The release timing differs by more than three years. AMD released on January 3, 2023, while NVIDIA released on May 31, 2026. Both are marked as Active production status. The RX 7600M has a known TDP of 90 W, while the N1 20SM has no TDP listed, making power comparisons impossible from the data.

Head-to-Head Benchmarks

The head-to-head benchmark table is empty, with no recorded tests between the two GPUs. The winsA and winsB counters both read zero. Consequently, no direct comparison scores exist to walk through. The only benchmark data available is the RX 7600M's Geekbench OpenCL score of 63775.

The nearest rivals for the RX 7600M provide context for its performance tier. The AMD Radeon RX 9060 XT LP scores 63830, which is 0.1% higher than the RX 7600M. The NVIDIA CMP 30HX also scores 63842, again 0.1% higher. The AMD Radeon Pro Vega 56 scores 63693, which is 0.1% lower. The AMD Radeon Pro WX 9100 scores 64212, which is 0.7% higher. These deltas show the RX 7600M sits within a tight cluster of GPUs, all within 1% of each other.

The N1 20SM has no rivals listed and no scores, so it cannot be positioned relative to any other GPU in the database. Its percentile rank of 50 is the default baseline, not a measured performance indicator.

For the RX 7600M, the compute metrics reinforce its OpenCL standing. The 17.27 TFLOPS FP32 and 34.55 TFLOPS FP16 (2:1) indicate a balanced compute architecture. The texture rate of 269.9 GTexel/s and pixel rate of 154.2 GPixel/s suggest strong fill rates for its class. The memory bandwidth of 256.0 GB/s from 8 GB GDDR6 on a 128-bit bus is typical for a mobile part in the RX 7000 series.

For the N1 20SM, the available numbers show a different profile. The 12.01 TFLOPS FP32 and equal 12.01 TFLOPS FP16 (1:1) indicate no FP16 acceleration advantage. The texture rate of 375.4 GTexel/s exceeds the AMD part by 39.0%. The pixel rate of 56.30 GPixel/s is 63.5% lower than the AMD part. The memory bandwidth of 273.2 GB/s from 128 GB LPDDR5X on a 256-bit bus is the standout specification.

The clock behavior differs notably. The RX 7600M boosts to 2410 MHz with a base of 1500 MHz, a 910 MHz boost range. The N1 20SM boosts to 2346 MHz from a 741 MHz base, a 1605 MHz boost range. The NVIDIA part has a much wider boost window, suggesting aggressive power management. The AMD game clock of 2070 MHz provides a stable midpoint for sustained workloads.

The process nodes are close, 6 nm versus 5 nm, both from TSMC. The transistor density favors AMD at 65.2 million per square millimeter, though the NVIDIA transistor count is unknown, preventing a direct density comparison. The die size difference of 178 mm² favors NVIDIA in terms of raw silicon area but does not translate to measured performance advantages in the absence of benchmarks.

The RX 7600M's release date of January 3, 2023, and its predecessor Polaris Mobile indicate a clear product lineage. The N1 20SM's release date of May 31, 2026, with no predecessor or successor, marks it as a newer, isolated entry in the database. The production status for both is Active.

The API support asymmetry is critical: the RX 7600M supports mainstream graphics APIs, while the N1 20SM lists none. This suggests the NVIDIA part may target non-graphics workloads, which aligns with its tensor cores and massive memory pool. The RX 7600M, with 28 ray tracing cores and full DirectX 12 Ultimate support, is positioned for conventional gaming and graphics tasks.

The database contains no paired performance measurements, so the only defensible conclusion is that the RX 7600M has verified compute performance while the N1 20SM does not. The architectural differences are substantial, but without benchmark data, the N1 20SM remains an unquantified product. The RX 7600M's 89th percentile ranking and cluster of rivals within 0.7% confirm its position as a solid mid-tier performer. The N1 20SM's 50th percentile and zero scores provide no basis for performance claims.
