AMD Radeon RX 7800M vs NVIDIA N1X 48SM Comparison

Head-to-Head Benchmarks

The database does not contain any direct head-to-head benchmark results between the AMD Radeon RX 7800M and the NVIDIA N1X 48SM. The head-to-head benchmark array is empty, and the win counts for both processors are zero. Consequently, any comparison between these two mobile graphics solutions must be constructed from their individual recorded performance metrics and architectural specifications.

The AMD Radeon RX 7800M has a full set of benchmark scores recorded in the database. Its average benchmark score is 27883, placing it at the 73rd percentile among all GPUs. Its nearest rivals in the database include the AMD Radeon Pro Vega 20 with an average score of 27839 (0.2% lower), the AMD Radeon Pro W5500X with 27973 (0.3% higher), the NVIDIA GeForce GTX 980 Ti with 28020 (0.5% higher), and the AMD FirePro S7150 with 28117 (0.8% higher). This places the RX 7800M in a tightly packed performance band where it trails its closest competitors by less than one percent.

The NVIDIA N1X 48SM has no recorded benchmark scores in the database. Its average benchmark score is listed as 0, and its percentile rank is 50. There are no nearest rivals recorded for this part. The absence of benchmark data means the N1X 48SM cannot be directly positioned against the RX 7800M using measured performance results.

The RX 7800M's individual benchmark results show its strongest showing in Geekbench Vulkan with a score of 126668, followed by Geekbench OpenCL at 120778. In Passmark tests, the G3D score is 17613, the GPU compute score is 9342, and the G2D score is 892. DirectX legacy tests show Passmark DirectX 11 at 176, DirectX 9 at 174, DirectX 10 at 99, and DirectX 12 at 89. The 3DMark Steel Nomad DX12 test records a score of 2994.

Because the N1X 48SM lacks any recorded scores, the head-to-head comparison is limited to architectural and specification differences. The RX 7800M's measured data indicates a GPU that competes within one percent of several established desktop and workstation parts. The N1X 48SM's performance profile remains entirely unquantified in the database.

Where Each One Wins

The AMD Radeon RX 7800M wins in measured performance categories because it is the only one of the two with recorded benchmark scores. It has a 73rd percentile rank among all GPUs, an average benchmark score of 27883, and a complete suite of DirectX, OpenCL, Vulkan, and Passmark results. Its FP32 throughput of 35.87 TFLOPS exceeds the N1X 48SM's 28.83 TFLOPS by approximately 24%. Its pixel rate of 224.2 GPixel/s is nearly double the N1X 48SM's 112.6 GPixel/s. Its memory bandwidth of 432.0 GB/s is roughly 58% higher than the N1X 48SM's 273.2 GB/s.

The NVIDIA N1X 48SM wins in raw resource counts. It has 6144 shading units versus 3840, 384 texture mapping units versus 240, and 192 tensor cores, a category where the RX 7800M has no recorded tensor core count. Its texture rate of 900.9 GTexel/s exceeds the RX 7800M's 560.4 GTexel/s. Its memory capacity of 128 GB is over ten times the RX 7800M's 12 GB, though its bandwidth is lower. The N1X 48SM also uses a PCIe 5.0 x16 interface while the RX 7800M uses PCIe 4.0 x16.

For gaming and general 3D workloads, the RX 7800M has the advantage of proven DirectX 12 Ultimate support and measured GPU scores. For compute tasks that leverage tensor cores, texture throughput, or large memory capacity, the N1X 48SM has the architectural edge, though no measured results confirm this.

Specification Differences

The two GPUs differ across nearly every recorded specification field.

The AMD Radeon RX 7800M uses the Navi 32 chip with RDNA 3.0 architecture and the codename Wheat Nas. It belongs to the Navi Mobile (RX 7000M) generation. The NVIDIA N1X 48SM uses the GB20B chip with Blackwell 2.0 architecture and belongs to the Blackwell IGP (N1x) generation.

The RX 7800M has a base clock of 1295 MHz, a boost clock of 2335 MHz, and a game clock of 2145 MHz. The N1X 48SM has a base clock of 741 MHz and a boost clock of 2346 MHz, with no game clock recorded. Memory clocks differ as well: the RX 7800M runs at 2250 MHz with 18 Gbps effective, while the N1X 48SM runs at 1067 MHz with 8.5 Gbps effective.

Memory configurations diverge sharply. The RX 7800M has 12 GB of GDDR6 on a 192-bit bus with 432.0 GB/s bandwidth. The N1X 48SM has 128 GB of LPDDR5X on a 256-bit bus with 273.2 GB/s bandwidth.

Core counts differ: the RX 7800M has 3840 shading units, 240 TMUs, 96 ROPs, and 60 ray tracing cores. The N1X 48SM has 6144 shading units, 384 TMUs, 48 ROPs, 48 ray tracing cores, and 192 tensor cores.

The RX 7800M has a TDP of 180 W. The N1X 48SM has an unknown TDP. Both are listed as IGP slot width with no power connectors. The RX 7800M uses PCIe 4.0 x16, while the N1X 48SM uses PCIe 5.0 x16. Display outputs are portable device dependent for the RX 7800M, while the N1X 48SM has 1x HDMI.

Transistor counts and die sizes also differ. The RX 7800M has 28,100 million transistors on a 346 mm² die with a density of 81.2M per mm². The N1X 48SM has an unknown transistor count on a 382 mm² die with no density recorded. Both use a 5 nm process at TSMC.

Release dates are far apart. The RX 7800M launched on 2024-09-10, while the N1X 48SM is dated 2026-05-31.

Architecture Differences

The AMD Radeon RX 7800M is built on RDNA 3.0 architecture, implemented with the Navi 32 chip at TSMC's 5 nm process. It integrates 28,100 million transistors on a 346 mm² die, yielding a transistor density of 81.2M per mm². Its RDNA 3.0 design provides 60 ray tracing cores, 3840 shading units, 240 texture mapping units, and 96 ROPs. The architecture supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Its memory system uses GDDR6 on a 192-bit interface.

The NVIDIA N1X 48SM is built on Blackwell 2.0 architecture, implemented with the GB20B chip, also at TSMC's 5 nm process. Its die size is 382 mm², slightly larger than the RX 7800M's 346 mm², though its transistor count is unknown. The Blackwell 2.0 design includes 192 tensor cores, a feature entirely absent from the RX 7800M's recorded specifications. The N1X 48SM has 48 ray tracing cores, 6144 shading units, 384 texture mapping units, and 48 ROPs. Its API support is recorded as N/A for DirectX, OpenGL, and Vulkan, which suggests it is not positioned for conventional graphics API workloads in the same manner as the RX 7800M.

The memory architecture differs fundamentally. The RX 7800M uses dedicated GDDR6 memory with a narrow 192-bit bus but high bandwidth of 432.0 GB/s. The N1X 48SM uses LPDDR5X unified memory with a wider 256-bit bus but lower bandwidth of 273.2 GB/s. The N1X 48SM's 128 GB capacity is substantially larger, which may indicate a focus on large working sets rather than bandwidth-sensitive workloads.

The RX 7800M's FP16 throughput matches its FP32 throughput at a 1:1 ratio, delivering 35.87 TFLOPS for both. The N1X 48SM also has a 1:1 FP16 to FP32 ratio, with both at 28.83 TFLOPS. Texture rate favors the N1X 48SM at 900.9 GTexel/s versus 560.4 GTexel/s, while pixel rate favors the RX 7800M at 224.2 GPixel/s versus 112.6 GPixel/s.

The RX 7800M belongs to the Navi Mobile (RX 7000M) generation and lists Polaris Mobile as its predecessor. The N1X 48SM belongs to the Blackwell IGP (N1x) generation with no predecessor recorded. Both are integrated graphics packages with no power connectors, and neither has a recorded launch MSRP.
