AMD Radeon 780M vs NVIDIA N1X 48SM Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries for the AMD Radeon 780M and the NVIDIA N1X 48SM. However, the available recorded measurements for the AMD Radeon 780M provide a baseline for comparison, while the NVIDIA N1X 48SM has no benchmark scores recorded in the database at this time.

The AMD Radeon 780M shows a 3DMark Steel Nomad DX12 score of 480 points. In Geekbench OpenCL, it records 18,602 points. Its Geekbench Vulkan score reaches 33,683 points. These three results give the Radeon 780M an average benchmark score of 17,588. Its percentile ranking against all GPUs sits at 61, meaning it outperforms roughly three-fifths of the tested GPU pool.

The NVIDIA N1X 48SM currently has no benchmark entries, no average score, and no rival comparisons in the database. Its percentile ranking against all GPUs is 50, which places it at the midpoint of the distribution in the absence of measured data.

Looking at the Radeon 780M's nearest rivals in the database clarifies its standing. The AMD Radeon Pro 560 averages 17,551 points, which is 0.2% below the 780M. The AMD Radeon Pro 460 averages 17,509 points, 0.5% lower. On the other side, the NVIDIA GeForce RTX 4060 averages 17,639 points, 0.3% above the 780M. The AMD Radeon HD 7790 averages 17,666 points, 0.4% higher. These are tight margins. The 780M sits within a fraction of a percent of all four rivals, indicating that its measured performance clusters closely with a range of older discrete and modern midrange parts.

Because the N1X 48SM lacks any benchmark data, no delta percentages can be calculated against the 780M. The comparison rests entirely on architectural and specification differences. The recorded data cannot confirm which part wins in any test. The 780M has concrete scores; the N1X 48SM does not. Any claim of victory for either side would exceed what the database supports.

The absence of head-to-head results means the 780M holds a 0 win count and the N1X 48SM holds a 0 win count in the direct comparison table. The Radeon 780M remains the only one of the two with verified performance numbers.

The Verdict

The data supports a straightforward assessment. The AMD Radeon 780M has measured benchmark results across three tests, an average score of 17,588, and a 61st percentile ranking. The NVIDIA N1X 48SM has no benchmark scores, an average score of zero, and a 50th percentile ranking that reflects an unmeasured device.

A builder looking for a part with confirmed performance should select the Radeon 780M. Its recorded scores place it within 0.4% of the AMD Radeon HD 7790, within 0.3% of the GeForce RTX 4060, and ahead of both the Radeon Pro 560 and Radeon Pro 460. Those margins are small, but they are real measurements. The 780M is an active production part with a release date of January 30, 2024, and it supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. It has no launch MSRP recorded in the database.

The NVIDIA N1X 48SM is an active production part scheduled for release on May 31, 2026, with a later release date than the 780M. It has no API support recorded for DirectX, OpenGL, or Vulkan, which are all marked as N/A. Its power connectors are listed as None and its slot width is IGP, matching the 780M's integrated form factor. However, without benchmark data, the database cannot rank its actual performance.

For a system that requires verified graphics performance today, the Radeon 780M is the only defensible choice from the recorded data. The N1X 48SM may offer substantial theoretical capability based on its specifications, but the database has no measurements to confirm that. The verdict is not about which part is architecturally superior. It is about which part has evidence. The 780M has evidence. The N1X 48SM does not.

Specification Differences

The AMD Radeon 780M and NVIDIA N1X 48SM differ across nearly every major specification field.

The 780M uses the Phoenix chip with RDNA 3.0 architecture, built on a 4 nm process at TSMC. It contains 25,390 million transistors on a 178 mm² die, giving a transistor density of 142.6 million transistors per square millimeter. The N1X 48SM uses the GB20B chip with Blackwell 2.0 architecture, built on a 5 nm process at TSMC. Its transistor count is listed as unknown and its die size is 382 mm², which is more than double the 780M's die area.

Clock speeds differ substantially. The 780M has a base clock of 800 MHz and a boost clock of 2900 MHz. The N1X 48SM has a base clock of 741 MHz and a boost clock of 2346 MHz. Both are lower than the 780M's figures, though the N1X 48SM has a much larger execution resource pool.

Memory configurations are completely different. The 780M uses system shared memory with no dedicated VRAM, no dedicated bus width, and bandwidth that depends on the host system. The N1X 48SM has 128 GB of LPDDR5X memory on a 256-bit bus with 273.2 GB/s of bandwidth. Its memory clock is listed as 1067 MHz with 8.5 Gbps effective transfer.

Compute unit counts show the scale difference. The 780M has 768 shading units, 48 texture mapping units, 32 ROPs, and 12 ray tracing cores. It has no tensor cores. The N1X 48SM has 6,144 shading units, 384 TMUs, 48 ROPs, 48 ray tracing cores, and 192 tensor cores. The N1X 48SM has 8 times the shading units, 8 times the TMUs, 1.5 times the ROPs, 4 times the ray tracing cores, and a unique tensor core array.

Fill rates and compute throughput reflect the resource gap. The 780M delivers 92.80 GPixel/s pixel rate, 139.2 GTexel/s texture rate, and 8.909 TFLOPS FP32. The N1X 48SM delivers 112.6 GPixel/s, 900.9 GTexel/s, and 28.83 TFLOPS FP32. Both parts list FP16 at a 1:1 ratio with FP32. The N1X 48SM's texture rate is roughly 6.5 times higher and its FP32 throughput is roughly 3.2 times higher.

Bus interface and display outputs differ. The 780M uses PCIe 4.0 x8 and its display outputs are motherboard dependent. The N1X 48SM uses PCIe 5.0 x16 and has one HDMI output. Both are IGP slot width with no power connectors. The 780M has a TDP of 15 W, while the N1X 48SM has an unknown TDP.

API support also diverges sharply. The 780M lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1X 48SM lists N/A for all three APIs.

Release timing is far apart. The 780M released on January 30, 2024. The N1X 48SM has a release date of May 31, 2026. Neither part has a recorded launch MSRP.

Architecture Differences

The architectural split between these two integrated GPUs is significant. The AMD Radeon 780M uses RDNA 3.0 architecture on a 4 nm TSMC process. It belongs to the Navi III IGP (Phoenix) generation and lists Navi II IGP as its predecessor and Navi III IGP as its successor. The NVIDIA N1X 48SM uses Blackwell 2.0 architecture on a 5 nm TSMC process and belongs to the Blackwell IGP (N1x) generation. It has no predecessor or successor listed.

The manufacturing node gives the 780M a density advantage. Its 4 nm process allows 25,390 million transistors on a 178 mm² die, which works out to 142.6 million transistors per square millimeter. The N1X 48SM uses a larger 5 nm process and a 382 mm² die, but its transistor count is unknown, so density cannot be calculated.

The execution architecture differs in fundamental ways. The 780M is built around 768 shaders arranged with 48 TMUs and 32 ROPs. It includes 12 ray tracing cores but no tensor cores. The N1X 48SM scales up to 6,144 shaders with 384 TMUs and 48 ROPs. It includes 48 ray tracing cores and 192 tensor cores. The tensor core presence is the clearest architectural distinction. The 780M has no AI acceleration hardware, while the N1X 48SM dedicates 192 tensor cores to that role.

Clock behavior reflects different design goals. The 780M boosts to 2900 MHz, which is high for an integrated part and helps compensate for its smaller execution width. The N1X 48SM boosts to 2346 MHz, a lower frequency, but its much larger shader count and texture unit count produce higher absolute throughput. The 780M's FP32 output is 8.909 TFLOPS. The N1X 48SM's FP32 output reaches 28.83 TFLOPS, a 3.2 times advantage.

Memory architecture is also a major differentiator. The 780M relies entirely on system shared memory, with no dedicated VRAM and bandwidth that varies by host platform. The N1X 48SM integrates 128 GB of LPDDR5X on a 256-bit bus with 273.2 GB/s of dedicated bandwidth. This removes the 780M's dependence on system memory performance and gives the N1X 48SM a fixed, high-bandwidth memory subsystem.

API support marks another architectural difference. The 780M is a fully featured graphics part with DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4 support. The N1X 48SM lists N/A for DirectX, OpenGL, and Vulkan. This suggests the N1X 48SM may target a different workload profile, though the database does not specify what that profile is.

The power envelope differs as well. The 780M is rated at 15 W TDP. The N1X 48SM has an unknown TDP, though both parts use no power connectors and occupy an IGP slot width. The N1X 48SM's larger die and higher throughput suggest a higher power draw, but the database does not confirm this.

Where Each One Wins

The AMD Radeon 780M wins in the areas where the database has actual measurements. It has a verified average benchmark score of 17,588, a 61st percentile ranking, and three recorded test results. It also supports a full modern API stack with DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. Its 15 W TDP and motherboard dependent display outputs make it suitable for compact integrated systems. It is available now, with a release date of January 30, 2024, and it holds a small measured advantage over the Radeon Pro 560 and Radeon Pro 460 in the database's nearest rival list.

The NVIDIA N1X 48SM wins in raw specification comparisons. It has 6,144 shading units versus 768, 384 TMUs versus 48, and 48 ROPs versus 32. Its FP32 throughput of 28.83 TFLOPS is more than triple the 780M's 8.909 TFLOPS. Its texture rate of 900.9 GTexel/s dwarfs the 780M's 139.2 GTexel/s. Its dedicated 128 GB LPDDR5X memory with 273.2 GB/s bandwidth removes the system memory dependency that limits the 780M. It has 48 ray tracing cores and 192 tensor cores, while the 780M has 12 ray tracing cores and no tensor cores.

The N1X 48SM also wins in bus connectivity. It uses PCIe 5.0 x16, a wider and newer interface than the 780M's PCIe 4.0 x8. Its die size of 382 mm² is more than double the 780M's 178 mm², which reflects a much larger implementation. Its pixel rate of 112.6 GPixel/s exceeds the 780M's 92.80 GPixel/s. Its release date of May 31, 2026 places it in a later generation.

The practical split is clear. The 780M is the part with proven, recorded performance and broad API support. The N1X 48SM is the part with superior theoretical specifications but no benchmark confirmation in the database. For software that relies on established graphics APIs and requires a working GPU today, the 780M has the evidence. For workloads that can use tensor cores, dedicated memory bandwidth, and massive shader throughput, the N1X 48SM has the architectural foundation, but the database cannot confirm how that translates into real scores.

Neither part has a recorded head-to-head win in the database. The 780M's wins are its measured benchmarks and API compatibility. The N1X 48SM's wins are its specification sheet. Builders must weigh verified data against unverified claims. The recorded data favors the 780M for immediate deployment. The N1X 48SM remains an unmeasured quantity.
