AMD Radeon RX 7700 XT vs NVIDIA N1 20SM Comparison

The Verdict

The AMD Radeon RX 7700 XT is the clear performance leader between these two parts, but the NVIDIA N1 20SM serves a completely different purpose. The RX 7700 XT is a discrete graphics card with 3456 shading units, 54 ray tracing cores, and a 245 W TDP, built for high-frame-rate gaming and compute workloads. The N1 20SM is an integrated graphics processor with 2560 shading units, 20 ray tracing cores, 80 tensor cores, and no published TDP, designed for a different class of system. The data shows the RX 7700 XT delivers 35.17 TFLOPS FP32 performance against the N1 20SM's 12.01 TFLOPS, a near threefold advantage in raw compute throughput. For anyone building a gaming desktop, the RX 7700 XT is the only choice between these two. The N1 20SM, with 128 GB of LPDDR5X memory and a PCIe 5.0 x16 interface, appears aimed at integrated or embedded platforms where the massive memory pool and tensor cores matter more than raw graphics speed.

The benchmark database places the RX 7700 XT at the 67th percentile among all GPUs, with an average benchmark score of 22549. Its nearest rivals include the NVIDIA GeForce RTX 2080 at 22895 (1.5% ahead), the RTX 4060 Mobile at 22729 (0.8% ahead), the RTX 5060 Mobile at 22435 (0.5% behind), and the AMD Radeon RX 5700 at 22170 (1.7% behind). The N1 20SM has no recorded benchmarks and sits at the 50th percentile with an average score of zero, which places it in a different tier entirely. The verdict is straightforward: the RX 7700 XT for gaming and general GPU compute, the N1 20SM for specialized integrated deployments where its unique memory configuration and tensor core count are relevant.

Where Each One Wins

The RX 7700 XT wins in every measured benchmark category where data exists. Its 3DMark Steel Nomad DX12 score of 3316, Geekbench OpenCL score of 138383, and Geekbench Vulkan score of 46443 demonstrate strong DirectX 12 and cross-API performance. PassMark results show 22547 in G3D, 12912 in GPU compute, 1161 in G2D, and legacy DirectX scores of 294 (DX9), 232 (DX11), 119 (DX10), and 79 (DX12). The N1 20SM has no benchmark entries, so the recorded data gives every win to the AMD card.

Where the N1 20SM appears to hold an advantage is in memory capacity and interface features. It carries 128 GB of LPDDR5X on a 256-bit bus, compared to the RX 7700 XT's 12 GB of GDDR6 on a 192-bit bus. The N1 20SM also uses PCIe 5.0 x16, a newer bus standard than the RX 7700 XT's PCIe 4.0 x16. The 80 tensor cores on the N1 20SM suggest a design intended for AI inference workloads, though no benchmark data confirms this. The RX 7700 XT has no tensor cores listed, so the N1 20SM is the only one of the two with dedicated tensor hardware.

Architecture Differences

The two GPUs come from different architecture families with distinct design priorities. The AMD Radeon RX 7700 XT uses the Navi 32 chip on RDNA 3.0 architecture, codenamed Wheat Nas, part of the Navi III (RX 7000) generation. It is manufactured on a 5 nm process at TSMC with 28,100 million transistors on a 346 mm² die, yielding a transistor density of 81.2M per mm². The NVIDIA N1 20SM uses the GB20B chip on Blackwell 2.0 architecture, part of the Blackwell IGP (N1x) generation, also on a 5 nm TSMC process. Its die size is 382 mm², larger than the AMD chip, but its transistor count is listed as unknown.

The RX 7700 XT has significantly more graphics hardware: 3456 shading units, 216 texture mapping units, and 96 render output units, against the N1 20SM's 2560 shading units, 160 TMUs, and 24 ROPs. The pixel rate difference is substantial: 244.2 GPixel/s for the AMD card versus 56.30 GPixel/s for the NVIDIA part. Texture rate similarly favors AMD at 549.5 GTexel/s versus 375.4 GTexel/s. The N1 20SM counters with 80 tensor cores, hardware the RX 7700 XT does not have. Both have ray tracing cores, with the RX 7700 XT carrying 54 versus the N1 20SM's 20.

Clock speeds tell a partial story. The RX 7700 XT runs at a base clock of 1435 MHz, a game clock of 2171 MHz, and a boost clock of 2544 MHz. The N1 20SM has a 741 MHz base clock and a 2346 MHz boost clock, with no game clock listed. Memory clocks differ as well: the RX 7700 XT uses 2250 MHz with 18 Gbps effective throughput, while the N1 20SM runs at 1067 MHz with 8.5 Gbps effective. The AMD card's memory bandwidth of 432.0 GB/s exceeds the N1 20SM's 273.2 GB/s despite the NVIDIA part having a wider 256-bit bus, because the GDDR6 memory runs at a much higher effective speed.

FAQ

Q: Which GPU has higher raw compute performance?

A: The AMD Radeon RX 7700 XT delivers 35.17 TFLOPS FP32 and 35.17 TFLOPS FP16 (1:1 ratio), while the NVIDIA N1 20SM delivers 12.01 TFLOPS FP32 and 12.01 TFLOPS FP16 (1:1 ratio). The AMD part holds a roughly threefold advantage in both precision formats.

Q: Does the NVIDIA N1 20SM have more memory than the AMD card?

A: Yes. The N1 20SM has 128 GB of LPDDR5X on a 256-bit bus with 273.2 GB/s bandwidth, whereas the RX 7700 XT has 12 GB of GDDR6 on a 192-bit bus with 432.0 GB/s bandwidth. The AMD card has higher bandwidth, but the NVIDIA part has over ten times the capacity.

A: The RX 7700 XT's average benchmark score of 22549 is 0.5% ahead of the RTX 5060 Mobile (22435), 0.8% behind the RTX 4060 Mobile (22729), 1.5% behind the RTX 2080 (22895), and 1.7% ahead of the RX 5700 (22170). It ranks in the 67th percentile among all GPUs.

Head-to-Head Benchmarks

The head-to-head benchmark table is empty, and the N1 20SM has no individual benchmark scores in the database. This makes a direct comparison of measured results impossible. However, the specification data provides a clear picture of expected performance gaps.

The largest advantage for the RX 7700 XT comes from its FP32 compute throughput. At 35.17 TFLOPS, it outperforms the N1 20SM's 12.01 TFLOPS by approximately 193%. This translates directly to faster shader processing, which drives frame rates in games and throughput in compute workloads. The pixel rate gap is even more pronounced: 244.2 GPixel/s versus 56.30 GPixel/s, a 334% advantage for the AMD card. Texture rate follows with 549.5 GTexel/s versus 375.4 GTexel/s, a 46% lead.

Memory bandwidth also favors the RX 7700 XT at 432.0 GB/s versus 273.2 GB/s, a 58% advantage. This matters for high-resolution textures and memory-intensive workloads. The RX 7700 XT's boost clock of 2544 MHz exceeds the N1 20SM's 2346 MHz, and its base clock of 1435 MHz is nearly double the NVIDIA part's 741 MHz. The N1 20SM's only measured hardware advantages are its 128 GB memory capacity, 80 tensor cores, and PCIe 5.0 x16 interface. None of these appear in benchmark scores, since the N1 20SM has no recorded results.

The RX 7700 XT's 3DMark Steel Nomad DX12 score of 3316 and Geekbench Vulkan score of 46443 confirm strong modern API performance. PassMark G3D at 22547 and GPU compute at 12912 show balanced raster and compute capabilities. Legacy DirectX tests show 294 in DX9, 232 in DX11, 119 in DX10, and 79 in DX12, with the lower DX12 score likely reflecting a different workload profile than the 3DMark result. The N1 20SM has no comparable data points, so every recorded benchmark result favors the AMD card.
