AMD Radeon RX 7700 vs NVIDIA N1 20SM Comparison

Where Each One Wins

The recorded data splits these two GPUs into completely different performance tiers. The AMD Radeon RX 7700 has nine benchmark scores across DirectX 9, 10, 11, 12, OpenCL, compute, and general 2D/3D workloads. Its average benchmark score is 15,852, and it sits at the 58th percentile among all GPUs in the database. The NVIDIA N1 20SM, by contrast, has zero recorded benchmark scores, an average benchmark score of 0, and a 50th percentile placement. This means every performance comparison must be derived from the AMD card's absolute numbers, because the NVIDIA part has no measured results to compare directly.

The AMD Radeon RX 7700 wins in every benchmark category where data exists, simply because it is the only part with data. Its strongest recorded result is in Geekbench OpenCL at 106,028 points. Its PassMark G3D score of 20,974 indicates solid general 3D rendering capability. The PassMark GPU Compute score of 10,963 shows the card handles compute workloads with meaningful throughput. The DirectX 12 score of 96 and DirectX 11 score of 186 place the card in a specific performance band for those APIs. The DirectX 9 score of 261 is notably higher than the DirectX 10 score of 92, which reflects the architecture's handling of legacy workloads.

The NVIDIA N1 20SM has no wins in any recorded test. Its only performance-related data points are architectural: 12.01 TFLOPS FP32, 375.4 GTexel/s texture rate, and 56.30 GPixel/s pixel rate. These figures are lower than the AMD card's corresponding values of 25.18 TFLOPS, 393.4 GTexel/s, and 236.1 GPixel/s. The AMD card also leads in memory bandwidth at 624.1 GB/s versus 273.2 GB/s for the NVIDIA part. The use-case split is therefore unambiguous: the AMD Radeon RX 7700 delivers measurable performance across every benchmark in the database, while the NVIDIA N1 20SM offers no verifiable benchmark results to establish any workload advantage.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries for these two GPUs. The headToHeadBenchmarks array is empty, and the win counts for both parts are zero. This absence of paired test results means the comparison must rely on the AMD card's individual benchmark scores and the NVIDIA card's architectural specifications.

The AMD Radeon RX 7700's benchmark suite provides the only measurable performance data. In 3DMark Steel Nomad DX12, the card scores 2,865. In Geekbench OpenCL, it scores 106,028. PassMark results include DirectX 9 at 261, DirectX 10 at 92, DirectX 11 at 186, DirectX 12 at 96, G2D at 1,206, G3D at 20,974, and GPU Compute at 10,963. These scores establish a performance profile across multiple generations of DirectX APIs and compute workloads.

The NVIDIA N1 20SM has no benchmark scores in the database. Its percentile placement of 50th among all GPUs appears alongside an average score of 0, which indicates the percentile is assigned based on specifications rather than measured results. Without recorded test data, no benchmark win can be attributed to the NVIDIA part.

The architectural comparison shows the AMD card leads in every throughput metric. The RX 7700's FP32 of 25.18 TFLOPS more than doubles the N1 20SM's 12.01 TFLOPS. The texture rate differs by a smaller margin: 393.4 GTexel/s versus 375.4 GTexel/s, a 4.8% advantage for AMD. The pixel rate gap is large: 236.1 GPixel/s versus 56.30 GPixel/s, a 319.5% advantage for AMD. Memory bandwidth also favors AMD at 624.1 GB/s versus 273.2 GB/s, a 128.4% advantage.

The only specification where the NVIDIA part leads is memory capacity. The N1 20SM has 128 GB of LPDDR5X, while the RX 7700 has 16 GB of GDDR6. This capacity difference does not translate into benchmark wins because no benchmarks exist for the NVIDIA part.

Specification Differences

The two GPUs differ across nearly every specification field. The AMD Radeon RX 7700 uses the Navi 32 chip, belongs to the Radeon RX 7000 series, and has the codename Wheat Nas. The NVIDIA N1 20SM uses the GB20B chip and belongs to the Blackwell IGP (N1x) generation.

Process node and foundry are identical: both use 5 nm process technology from TSMC. Transistor counts differ substantially. The AMD card has 28,100 million transistors on a 346 mm² die, yielding a transistor density of 81.2M per mm². The NVIDIA part's transistor count is listed as unknown on a 382 mm² die, with no density figure.

Clock speeds differ across the board. The AMD card's base clock is 1900 MHz, boost is 2459 MHz, and game clock is 2041 MHz. The NVIDIA part's base clock is 741 MHz, boost is 2346 MHz, and it has no game clock listed. Memory clocks also differ: the AMD card runs at 2438 MHz (19.5 Gbps effective), while the NVIDIA part runs at 1067 MHz (8.5 Gbps effective).

Memory subsystems diverge in capacity and type. The AMD card has 16 GB GDDR6 on a 256-bit bus. The NVIDIA part has 128 GB LPDDR5X on a 256-bit bus. Bandwidth favors AMD at 624.1 GB/s versus 273.2 GB/s.

Shader resources are partially shared. Both have 2,560 shading units and 160 texture mapping units. The AMD card has 96 ROPs, while the NVIDIA part has 24 ROPs. Ray tracing cores differ: 40 for AMD versus 20 for NVIDIA. Tensor cores exist only on the NVIDIA part, with 80 listed, while the AMD card has none.

Pixel and texture rates follow the ROP and TMU counts. The AMD card produces 236.1 GPixel/s and 393.4 GTexel/s. The NVIDIA part produces 56.30 GPixel/s and 375.4 GTexel/s. FP32 and FP16 throughput are both 25.18 TFLOPS for AMD and 12.01 TFLOPS for NVIDIA, with a 1:1 ratio for both.

Power and physical specifications differ. The AMD card has a TDP of 200 W, uses a dual-slot cooler, requires two 8-pin power connectors, and suggests a 550 W power supply. The NVIDIA part's TDP is unknown, it is an integrated graphics processor (IGP), has no power connectors, and lists no suggested PSU.

Bus interfaces differ by generation. The AMD card uses PCIe 4.0 x16. The NVIDIA part uses PCIe 5.0 x16. Display outputs also differ: the AMD card has 1x HDMI 2.1a, 2x DisplayPort 2.1, and 1x USB Type-C. The NVIDIA part has only 1x HDMI.

Dimensions are only recorded for the AMD card: 267 mm length, 135 mm height, and 50 mm width. The NVIDIA part has no dimension data.

Release dates differ by roughly eight months. The AMD card was released on 2025-09-17. The NVIDIA part was released on 2026-05-31. Both are listed as Active production status. The AMD card's predecessor is Navi II and successor is Navi IV. The NVIDIA part lists no predecessor or successor.

Architecture Differences

The AMD Radeon RX 7700 uses the RDNA 3.0 architecture, built on the Navi 32 chip. The NVIDIA N1 20SM uses the Blackwell 2.0 architecture, built on the GB20B chip. These are fundamentally different design philosophies: RDNA 3.0 is a discrete GPU architecture optimized for rasterization and compute throughput, while Blackwell 2.0 in this implementation is an integrated graphics processor (IGP) designed for a different power and thermal envelope.

The RDNA 3.0 architecture is a chiplet-based design, though the database does not specify chiplets for this particular card. The key architectural feature is the high ROP count of 96, which drives the pixel rate of 236.1 GPixel/s. The 40 ray tracing cores place the card in a mid-to-high tier for hardware ray tracing support within the Radeon RX 7000 series. The 2,560 shading units and 160 TMUs are identical to the NVIDIA part, but the AMD architecture pairs these with a much higher clock speed (2459 MHz boost versus 2346 MHz) and more than double the FP32 throughput.

The Blackwell 2.0 architecture in the N1 20SM is characterized by its tensor core count of 80. These tensor cores are absent from the AMD card, which means the NVIDIA part has dedicated hardware for AI and machine learning workloads that the AMD card does not. However, the database provides no benchmark results for the NVIDIA part, so the practical impact of these tensor cores on measured performance cannot be quantified. The NVIDIA architecture also has a significantly lower ROP count of 24, which limits its pixel throughput to 56.30 GPixel/s despite having the same number of shading units and TMUs as the AMD card.

Memory architecture differs in both type and capacity. The AMD card uses GDDR6, a dedicated graphics memory standard, while the NVIDIA part uses LPDDR5X, a low-power memory typically shared with system resources. The NVIDIA part's 128 GB capacity is 8 times larger than the AMD card's 16 GB, but its bandwidth of 273.2 GB/s is less than half of the AMD card's 624.1 GB/s. This suggests the NVIDIA part prioritizes capacity for integrated use cases, while the AMD card prioritizes bandwidth for graphics throughput.

The AMD card's API support includes DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA part lists all three APIs as N/A, which aligns with its IGP classification but means software compatibility cannot be assumed from the recorded data. The AMD card also has a broader display output configuration with HDMI 2.1a, dual DisplayPort 2.1, and a USB Type-C port, while the NVIDIA part has a single HDMI output.

Clock behavior reflects the different power envelopes. The AMD card has a base clock of 1900 MHz and a boost clock of 2459 MHz, with a game clock of 2041 MHz that sits between the two. The NVIDIA part has a much lower base clock of 741 MHz but a boost clock of 2346 MHz, which is close to the AMD card's boost. This large clock delta suggests the NVIDIA part is designed to idle at very low clocks and ramp up under load, consistent with an integrated part sharing thermal and power resources with a host system.

Transistor density is only recorded for the AMD card at 81.2M per mm². The NVIDIA part's transistor count is unknown, but its die size of 382 mm² is 36 mm² larger than the AMD card's 346 mm². Without transistor count data, the architectural complexity of the NVIDIA part cannot be directly compared to the AMD part. The AMD card's 28,100 million transistors on a smaller die indicate a denser implementation of the RDNA 3.0 architecture.
