AMD Radeon RX 7700S vs NVIDIA N1 20SM Comparison

AMD Radeon RX 7700S and NVIDIA N1 20SM represent two very different approaches to mobile graphics. The RX 7700S is a discrete-class part from AMD’s Radeon RX 7000 series, built for the Navi Mobile (RX 7000M) generation. The N1 20SM is an integrated graphics processor from NVIDIA’s Blackwell IGP (N1x) family. The recorded data shows a clear split: the RX 7700S has established benchmark results, while the N1 20SM currently has no recorded scores in the database. This makes direct numerical comparison impossible, but the specification sheets and available measurements allow for a detailed analysis of what each part delivers.

Head-to-Head Benchmarks

The database contains three benchmark results for the AMD Radeon RX 7700S. In 3DMark Steel Nomad DX12, it scores 2185. In Geekbench OpenCL, it scores 62983. In Geekbench Vulkan, it scores 36380. These results place the RX 7700S at the 78th percentile among all GPUs in the database. Its average benchmark score is 33849.

The NVIDIA N1 20SM has no benchmark entries. Its average benchmark score is recorded as 0, and its percentile versus all GPUs is 50. With no head-to-head benchmark data and zero recorded scores, the N1 20SM cannot be compared numerically to the RX 7700S in any direct test. The database shows winsA as 0 and winsB as 0, reflecting the absence of shared test results.

For context on the RX 7700S, the nearest rivals in the database include AMD Radeon HD 7950 with an average score of 33951, which places the RX 7700S 0.3% behind. The AMD Radeon RX 480 scores 33997, putting the RX 7700S 0.4% behind. The NVIDIA GeForce GTX 1060 5 GB scores 33694, with the RX 7700S 0.5% ahead. The NVIDIA RTX A5000 scores 33622, with the RX 7700S 0.7% ahead. These figures show the RX 7700S sits in a tight performance cluster around the 33.6k to 34.0k average score range, within roughly one percent of all four listed rivals.

The N1 20SM has no nearest rivals listed and no benchmark scores, so its real-world performance cannot be inferred from the database. All performance statements about the N1 20SM must rely on its architectural specifications rather than measured results.

Architecture Differences

The two GPUs come from different manufacturers and different architectures. The AMD Radeon RX 7700S uses the Navi 33 chip based on RDNA 3.0 architecture, with the codename Hotpink Bonefish. It belongs to the Navi Mobile (RX 7000M) generation. The NVIDIA N1 20SM uses the GB20B chip based on Blackwell 2.0 architecture, with no codename listed, and belongs to the Blackwell IGP (N1x) generation.

Process technology differs. The RX 7700S is fabricated by TSMC on a 6 nm process and contains 13,300 million transistors on a 204 mm² die, giving a transistor density of 65.2 million transistors per square millimeter. The N1 20SM is also fabricated by TSMC but on a 5 nm process. Its transistor count is listed as unknown, and its die size is 382 mm², which is notably larger than the RX 7700S die. No transistor density figure is recorded for the N1 20SM.

Clock speeds differ substantially. The RX 7700S has a base clock of 1500 MHz, a boost clock of 2500 MHz, and a game clock of 2200 MHz. Its memory clock is 2250 MHz with 18 Gbps effective. The N1 20SM has a much lower base clock of 741 MHz and a boost clock of 2346 MHz. It has no game clock listed, and its memory clock is 1067 MHz with 8.5 Gbps effective.

Memory configuration is a major difference. The RX 7700S has 8 GB of GDDR6 memory on a 128-bit bus, delivering 288.0 GB/s of bandwidth. The N1 20SM has 128 GB of LPDDR5X memory on a 256-bit bus, delivering 273.2 GB/s of bandwidth. The N1 20SM has 16 times the memory capacity but slightly lower bandwidth, 273.2 GB/s versus 288.0 GB/s.

Compute unit counts also differ. The RX 7700S has 2048 shading units, 128 texture mapping units, 64 raster output units, and 32 ray tracing cores. It has no tensor cores listed. The N1 20SM has 2560 shading units, 160 texture mapping units, 24 raster output units, 20 ray tracing cores, and 80 tensor cores. The N1 20SM has more shading units and more tensor cores, while the RX 7700S has more raster output units and more ray tracing cores.

Rates and throughput numbers reflect the architectural differences. The RX 7700S achieves a pixel rate of 160.0 GPixel/s and a texture rate of 320.0 GTexel/s. Its FP32 compute is 20.48 TFLOPS, and its FP16 compute is 40.96 TFLOPS at a 2:1 ratio. The N1 20SM achieves a pixel rate of 56.30 GPixel/s and a texture rate of 375.4 GTexel/s. Its FP32 compute is 12.01 TFLOPS, and its FP16 compute is 12.01 TFLOPS at a 1:1 ratio. The RX 7700S has a large lead in pixel rate and FP32 throughput, while the N1 20SM has a smaller lead in texture rate.

Power and interface details also differ. The RX 7700S has a TDP of 100 W, while the N1 20SM has an unknown TDP. Both are listed as IGP slot width with no power connectors. The RX 7700S uses a PCIe 4.0 x16 bus interface, while the N1 20SM uses PCIe 5.0 x16. Display outputs for the RX 7700S are listed as portable device dependent, while the N1 20SM has 1x HDMI.

API support differs sharply. The RX 7700S supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1 20SM lists DirectX as N/A, OpenGL as N/A, and Vulkan as N/A. This suggests the N1 20SM is not positioned for traditional PC graphics API workloads in the same way as the RX 7700S, based solely on the recorded data.

Release timing and production status also differ. The RX 7700S was released on 2023-01-03 and is listed as Active production. Its predecessor is Polaris Mobile. The N1 20SM has a release date of 2026-05-31, also listed as Active production, with no predecessor recorded.

Where Each One Wins

The RX 7700S wins clearly in measured graphics performance. Its three benchmark scores establish a baseline, and its 78th percentile ranking among all GPUs shows it sits above the median. Its FP32 compute of 20.48 TFLOPS is substantially higher than the N1 20SM’s 12.01 TFLOPS. Its pixel rate of 160.0 GPixel/s is nearly three times the N1 20SM’s 56.30 GPixel/s. The RX 7700S also has a higher memory bandwidth at 288.0 GB/s versus 273.2 GB/s, and its 18 Gbps effective memory clock is more than double the N1 20SM’s 8.5 Gbps effective.

The RX 7700S also leads in ray tracing core count with 32 versus 20, and it has a higher boost clock at 2500 MHz versus 2346 MHz. Its base clock is more than double the N1 20SM’s, 1500 MHz versus 741 MHz. The RX 7700S supports modern graphics APIs including DirectX 12 Ultimate and Vulkan 1.4, while the N1 20SM lists no API support in the database.

The N1 20SM wins in areas that favor its integrated design. It has 128 GB of LPDDR5X memory, a massive capacity advantage over the RX 7700S’s 8 GB. It has a wider 256-bit memory bus versus 128-bit. It has 2560 shading units versus 2048, 160 texture mapping units versus 128, and 80 tensor cores when the RX 7700S has none listed. Its texture rate of 375.4 GTexel/s exceeds the RX 7700S’s 320.0 GTexel/s. It uses a newer PCIe 5.0 x16 interface versus PCIe 4.0 x16, and it is fabricated on a newer 5 nm process compared to 6 nm.

The N1 20SM’s FP16 compute matches its FP32 compute at 12.01 TFLOPS with a 1:1 ratio, whereas the RX 7700S reaches 40.96 TFLOPS FP16 only at a 2:1 ratio. For workloads that rely on tensor operations, the N1 20SM has hardware the RX 7700S does not list.

The Verdict

The data supports a straightforward conclusion. The AMD Radeon RX 7700S is the part with proven graphics performance. It has benchmark scores, a 78th percentile ranking, and strong rasterization metrics such as 160.0 GPixel/s pixel rate and 20.48 TFLOPS FP32. Its nearest rivals all sit within one percent of its average score, which places it in a familiar performance tier for a mobile discrete GPU. The RX 7700S is the choice for any workload where measured graphics throughput matters, based on the recorded data.

The NVIDIA N1 20SM is a different kind of product. With no benchmark scores, no API support listed, and an unknown TDP, it does not present a comparable graphics performance profile. Its strengths lie in memory capacity, tensor core count, texture rate, and a newer PCIe interface. The 128 GB LPDDR5X memory and 80 tensor cores suggest a design aimed at memory-heavy or AI-oriented tasks rather than traditional rasterized graphics. Its 50th percentile placeholder ranking reflects the absence of data rather than a measured performance level.

The verdict from the database is clear: for anyone comparing these two on graphics benchmarks, the RX 7700S is the only one with recorded results. For anyone evaluating the N1 20SM, the lack of scores means no performance claims can be made from the database. The RX 7700S should be selected when measured graphics output is the priority. The N1 20SM should be considered only when its unique specifications, particularly the large memory pool and tensor cores, are directly relevant, and even then the lack of benchmark data leaves its actual capability unverified.
