AMD Radeon RX 7800 XT vs NVIDIA N1 16SM Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the AMD Radeon RX 7800 XT and the NVIDIA N1 16SM. The head-to-head benchmark list is empty, and neither product records a win in direct competition. This absence of comparative data means the two GPUs cannot be ranked against each other through matched testing. Instead, the available information consists of standalone benchmark scores for the AMD part and architectural specifications for both.

The AMD Radeon RX 7800 XT delivers a 3DMark Steel Nomad DX12 score of 4157. In Geekbench, it records 18290 in OpenCL and 54228 in Vulkan. PassMark results show 24176 in G3D, 13473 in GPU compute, 1177 in G2D, 304 in DirectX 9, 249 in DirectX 11, 121 in DirectX 10, and 93 in DirectX 12. The average benchmark score across all tests is 11627, placing it at the 51st percentile among all GPUs in the database.

The NVIDIA N1 16SM has no recorded benchmarks. Its average benchmark score is 0, and its percentile rank is 50, which reflects the absence of test data rather than a measured performance level. The nearest rivals for the AMD card provide context for its standalone scores. The NVIDIA GeForce GTX 1660 averages 11680, a delta of -0.5% relative to the RX 7800 XT, meaning the two are effectively tied. The AMD Radeon Pro 5500M averages 11528, placing it 0.9% behind the RX 7800 XT. The NVIDIA Tesla K20c averages 11479, which is 1.3% lower. The AMD Radeon RX 6500 XT averages 11842, putting it 1.8% ahead. These deltas indicate that the RX 7800 XT sits in a narrow performance band where its closest competitors are within roughly two percentage points in either direction.

Without head-to-head tests, the relative performance of the NVIDIA N1 16SM remains unquantified. The data cannot confirm whether it would outperform or underperform the RX 7800 XT in any workload. The only definitive statement from the benchmark section is that the RX 7800 XT has measured scores across multiple APIs and resolutions, while the N1 16SM has none.

Architecture Differences

The architectural gap between these two products is substantial. The AMD Radeon RX 7800 XT uses the Navi 32 chip built on RDNA 3.0 architecture, with the codename Wheat Nas. It belongs to the Navi III generation of the RX 7000 series. The NVIDIA N1 16SM uses the GB20B chip on Blackwell 2.0 architecture, classified as part of the Blackwell IGP generation under the N1x family. Both are fabricated on a 5 nm process at TSMC.

The AMD chip integrates 28,100 million transistors on a 346 mm² die, yielding a transistor density of 81.2 million per square millimeter. The NVIDIA chip has an unknown transistor count but a larger die size of 382 mm². Transistor density for the N1 16SM is not recorded in the database.

Clock speeds differ notably. The RX 7800 XT has a base clock of 1295 MHz, a boost clock of 2430 MHz, and a game clock of 2124 MHz. The N1 16SM has a base clock of 741 MHz and a boost clock of 2346 MHz, with no game clock listed. The AMD part runs its memory at 2438 MHz, which translates to 19.5 Gbps effective. The NVIDIA part runs memory at 1067 MHz, or 8.5 Gbps effective.

Memory capacity and type present a major divergence. The RX 7800 XT carries 16 GB of GDDR6 on a 256-bit bus, delivering 624.1 GB/s of bandwidth. The N1 16SM carries 128 GB of LPDDR5X on a 256-bit bus, but bandwidth reaches only 273.2 GB/s. The NVIDIA part quadruples the capacity while less than halving the bandwidth, a trade-off that suggests a very different intended workload.

Compute resources favor the AMD card substantially. The RX 7800 XT has 3840 shading units, 240 texture mapping units, and 96 raster output units. It also includes 60 ray tracing cores. The N1 16SM has 2048 shading units, 128 TMUs, and 24 ROPs, with 16 ray tracing cores. The NVIDIA part adds 64 tensor cores, a feature the AMD card lacks entirely. Pixel rate for the RX 7800 XT is 233.3 GPixel/s, versus 56.30 GPixel/s for the N1 16SM. Texture rate is 583.2 GTexel/s versus 300.3 GTexel/s. FP32 performance is 37.32 TFLOPS for the AMD card and 9.609 TFLOPS for the NVIDIA part. Both deliver FP16 at a 1:1 ratio with FP32.

The RX 7800 XT draws 263 W with a suggested power supply of 600 W, using dual 8-pin connectors and a dual-slot cooler. The N1 16SM is an integrated graphics processor, or IGP, with no power connectors and no recorded power draw. It uses PCIe 5.0 x16, while the AMD card uses PCIe 4.0 x16. Display outputs also differ: the RX 7800 XT offers one HDMI 2.1a and three DisplayPort 2.1 connections, while the N1 16SM provides a single HDMI output.

API support separates the two further. The RX 7800 XT supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1 16SM lists DirectX, OpenGL, and Vulkan as N/A. The physical dimensions of the RX 7800 XT are 267 mm in length, 111 mm in height, and 50 mm in width. The N1 16SM has no recorded dimensions. The RX 7800 XT was released on September 5, 2023, while the N1 16SM carries a release date of May 31, 2026. The AMD card lists its predecessor as Navi II and its successor as Navi IV. The NVIDIA part has no recorded predecessor or successor.

Where Each One Wins

Based strictly on recorded data, the AMD Radeon RX 7800 XT wins in every measurable performance category. It has higher pixel rate, higher texture rate, higher FP32 throughput, and higher memory bandwidth. Its shading unit count, TMU count, and ROP count all exceed those of the NVIDIA N1 16SM. Its ray tracing core count of 60 more than triples the 16 found on the NVIDIA part.

The NVIDIA N1 16SM wins only in areas unrelated to raw graphics throughput. It offers 128 GB of memory versus 16 GB, a 8x capacity advantage. It includes 64 tensor cores, which the AMD card does not have. It uses PCIe 5.0 x16, a newer bus interface than the PCIe 4.0 x16 on the AMD card. It is an IGP with no power connectors, meaning it can operate without external power, whereas the RX 7800 XT requires dual 8-pin connectors and a 600 W power supply. The NVIDIA part also has no recorded power draw, while the AMD part draws 263 W.

The RX 7800 XT is a discrete add-in board with active production status and a launch MSRP of 499 USD. The N1 16SM is an integrated processor with active production status but no launch MSRP. The AMD card has a full set of API support, while the NVIDIA part lists none. The RX 7800 XT supports multiple display outputs, while the N1 16SM has only one.

For gaming and traditional GPU workloads, the RX 7800 XT is the clear choice based on its benchmark scores and compute specifications. For scenarios requiring massive memory capacity, tensor core acceleration, or integrated operation with no external power, the N1 16SM holds advantages that the data can support. The lack of benchmarks for the NVIDIA part means its real-world performance in those scenarios cannot be quantified.

The Verdict

The data presents two fundamentally different products. The AMD Radeon RX 7800 XT is a discrete graphics card with measured performance across multiple benchmarks, a 51st percentile rank, and an average benchmark score of 11627. Its nearest rivals, the NVIDIA GeForce GTX 1660 and AMD Radeon RX 6500 XT, sit within 1.8 percentage points of its average score. The RX 7800 XT offers 3840 shading units, 60 ray tracing cores, and 624.1 GB/s of memory bandwidth, all of which are significantly higher than the NVIDIA N1 16SM.

The NVIDIA N1 16SM is an integrated processor with no benchmark data. Its 2048 shading units, 16 ray tracing cores, and 273.2 GB/s bandwidth place it below the AMD part in every compute specification. Its advantages are memory capacity at 128 GB, tensor cores at 64, and a PCIe 5.0 x16 interface. It also operates without external power, making it suitable for integrated deployments.

For users selecting a discrete graphics card for gaming or compute workloads with measurable performance, the RX 7800 XT is the only option with recorded data. For applications that require 128 GB of memory or tensor core acceleration in an integrated package, the N1 16SM offers those features, but its performance remains unverified in the database. The choice between them depends entirely on whether the workload demands the measured graphics throughput of the RX 7800 XT or the unique memory and tensor capabilities of the N1 16SM.
