AMD Radeon RX 7700S vs NVIDIA N1X 48SM Comparison

Head-to-Head Benchmarks

The recorded data presents an unusual comparison because the two GPUs have no overlapping benchmark entries. The AMD Radeon RX 7700S has three recorded results, while the NVIDIA N1X 48SM has none in the database. Direct numerical head-to-head scores are therefore unavailable. What can be compared are the architectural specifications and the AMD part's standing within the broader GPU landscape.

The RX 7700S achieves an average benchmark score of 33849 across its three tests. Its best single result is 62983 in Geekbench OpenCL, followed by 36380 in Geekbench Vulkan, and 2185 in 3DMark Steel Nomad DX12. The NVIDIA N1X 48SM holds an average benchmark score of 0, meaning no validated measurements exist yet. The percentile ranking reflects this gap: the RX 7700S sits at the 78th percentile among all GPUs, while the N1X 48SM sits at the 50th percentile, which is the default position for an unmeasured part.

The RX 7700S's nearest rivals in the database provide context for its performance tier. Its average score of 33849 places it within a tight cluster. The AMD Radeon HD 7950 scores 33951, a delta of -0.3 percent relative to the RX 7700S. The AMD Radeon RX 480 scores 33997, a delta of -0.4 percent. The NVIDIA GeForce GTX 1060 5 GB scores 33694, a delta of 0.5 percent. The NVIDIA RTX A5000 scores 33622, a delta of 0.7 percent. These deltas indicate that the RX 7700S performs within about one percent of all four rivals, making it a mid-pack contender rather than a standout in its immediate neighborhood. The largest recorded gap is the 0.7 percent advantage over the RTX A5000, and the largest deficit is 0.4 percent behind the RX 480.

Since the N1X 48SM has no scores, its performance can only be inferred from its raw compute specifications, not from measured results. Its FP32 throughput of 28.83 TFLOPS is 40.8 percent higher than the RX 7700S's 20.48 TFLOPS. Its texture rate of 900.9 GTexel/s is 181.5 percent higher than the RX 7700S's 320.0 GTexel/s. These figures suggest a higher theoretical ceiling, but without benchmark scores, the database cannot confirm real-world equivalence.

Where Each One Wins

The RX 7700S wins in any scenario where measured results matter. It has three validated benchmarks, a 78th percentile standing, and an average score of 33849. The N1X 48SM has no validated scores, so it cannot claim a single measured win. Its percentile of 50 is a placeholder, not a result.

The RX 7700S also wins on pixel throughput. Its pixel rate of 160.0 GPixel/s exceeds the N1X 48SM's 112.6 GPixel/s by 42.1 percent. This indicates an advantage in fill-rate-bound workloads, such as heavy rasterization at high resolutions. The RX 7700S also has more ROPs: 64 versus 48, a 33.3 percent advantage. For traditional pixel output, the AMD part is structurally stronger.

The N1X 48SM wins on compute density and memory capacity. Its FP32 output of 28.83 TFLOPS is 40.8 percent higher. Its FP16 output is identical to its FP32 at 28.83 TFLOPS, indicating a 1:1 ratio, whereas the RX 7700S reaches 40.96 TFLOPS FP16 at a 2:1 ratio. In workloads that use FP16 with the 2:1 path, the RX 7700S has a higher peak, but in FP16 workloads that require 1:1 throughput, the N1X 48SM's sustained rate may be more consistent.

The N1X 48SM holds a decisive advantage in memory capacity: 128 GB versus 8 GB. That is a 16x difference. Its memory bus is 256 bit versus 128 bit, doubling the interface width. Its bandwidth of 273.2 GB/s is slightly lower than the RX 7700S's 288.0 GB/s, a 5.1 percent deficit, but the capacity and bus width differences are far more significant for large datasets. The N1X 48SM also has 192 tensor cores, while the RX 7700S has none listed. Any AI or tensor-accelerated workload favors the NVIDIA part on paper.

Architecture Differences

The two GPUs come from different foundries and process nodes. The RX 7700S uses TSMC's 6 nm process, while the N1X 48SM uses TSMC's 5 nm process. The AMD chip is Navi 33, built on RDNA 3.0 architecture, with the codename Hotpink Bonefish. The NVIDIA chip is GB20B, built on Blackwell 2.0 architecture. The RX 7700S belongs to the Navi Mobile generation (RX 7000M), while the N1X 48SM belongs to the Blackwell IGP (N1x) generation.

The transistor counts differ sharply. The RX 7700S packs 13,300 million transistors on a 204 mm² die, yielding a density of 65.2 million transistors per mm². The N1X 48SM's transistor count is unknown, but its die size is 382 mm², which is 87.3 percent larger than the RX 7700S's die. The larger die with a newer process node suggests a substantially more complex chip, though the database does not record its transistor count.

Core configuration differences are substantial. The RX 7700S has 2048 shading units, 128 TMUs, 64 ROPs, and 32 ray tracing cores. The N1X 48SM has 6144 shading units, 384 TMUs, 48 ROPs, and 48 ray tracing cores. The NVIDIA part has 3x the shading units and 3x the TMUs, but 25 percent fewer ROPs. It also has 192 tensor cores, which have no counterpart in the RX 7700S specification. Clock speeds run in opposite directions: the RX 7700S has a base clock of 1500 MHz and a boost of 2500 MHz, while the N1X 48SM has a base of 741 MHz and a boost of 2346 MHz. The AMD part's base clock is 102.4 percent higher, and its boost is 6.6 percent higher.

Memory architecture differs by type and capacity. The RX 7700S uses 8 GB of GDDR6 on a 128 bit bus, with 2250 MHz memory clock and 18 Gbps effective speed, producing 288.0 GB/s bandwidth. The N1X 48SM uses 128 GB of LPDDR5X on a 256 bit bus, with 1067 MHz memory clock and 8.5 Gbps effective speed, producing 273.2 GB/s bandwidth. The interface also differs: the RX 7700S uses PCIe 4.0 x16, while the N1X 48SM uses PCIe 5.0 x16.

API support diverges completely. The RX 7700S supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1X 48SM lists N/A for DirectX, OpenGL, and Vulkan. This suggests the NVIDIA part is not aimed at conventional graphics APIs, reinforcing its positioning as a compute-oriented integrated GPU. The display outputs also differ: the RX 7700S is listed as Portable Device Dependent, while the N1X 48SM has 1x HDMI.

Power and physical specs show both are integrated parts. The RX 7700S has a TDP of 100 W, while the N1X 48SM's TDP is unknown. Both use IGP slot width and no power connectors. The RX 7700S has no suggested PSU listed, and neither part lists physical dimensions.

The release dates place these parts far apart. The RX 7700S was released on 2023-01-03, while the N1X 48SM is dated 2026-05-31. The RX 7700S's predecessor is Polaris Mobile, while the N1X 48SM has no predecessor listed. Both are marked as Active in production status.

The Verdict

The data supports a clear split. For any measured, validated graphics workload, the RX 7700S is the only part with evidence. It has three benchmark scores, a 78th percentile ranking, and a proven average score of 33849. The N1X 48SM has no scores, no rivals, and a default 50th percentile. On the basis of recorded data alone, the RX 7700S is the only verifiable graphics performer.

For compute-heavy tasks that can use the N1X 48SM's raw resources, the specification sheet favors NVIDIA. Its FP32 rate of 28.83 TFLOPS is 40.8 percent higher, its texture rate of 900.9 GTexel/s is 181.5 percent higher, and its 128 GB memory capacity is unmatched by the RX 7700S's 8 GB. The 192 tensor cores provide an AI capability that the RX 7700S simply does not list.

For pixel-bound rendering, the RX 7700S wins on pixel rate (160.0 GPixel/s versus 112.6 GPixel/s) and ROP count (64 versus 48). For bandwidth, the RX 7700S also leads slightly at 288.0 GB/s versus 273.2 GB/s. The AMD part is better suited to conventional rasterization. The NVIDIA part is better suited to large-scale compute, tensor workloads, and memory-hungry applications.

The API situation is decisive for gaming. The RX 7700S supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. The N1X 48SM lists no API support. Any gaming or traditional graphics application will favor the RX 7700S, and the N1X 48SM's lack of graphics API support makes it unsuitable for those tasks.
