Intel UHD Graphics 770 Mobile vs NVIDIA N1X 48SM Comparison

Intel UHD Graphics 770 Mobile is an integrated graphics solution built on Intel’s Generation 12.2 architecture, using the Raptor Lake chip. NVIDIA N1X 48SM is an integrated GPU from NVIDIA, based on the Blackwell 2.0 architecture and the GB20B chip. The database shows both are active products, with Intel’s unit releasing in January 2023 and NVIDIA’s unit scheduled for a May 2026 release. The two sit in the same percentile band, both at the 50th percentile against all GPUs, yet their specifications diverge sharply. This analysis relies solely on recorded data from the database, including clock speeds, memory configurations, compute units, and API support, to compare what each part offers.

Head-to-Head Benchmarks

The database does not contain direct head-to-head benchmark scores for these two GPUs. The entries for headToHeadBenchmarks are empty, and both parts have an average benchmark score of zero. There are no nearest rivals listed for either product, so no comparative performance percentages can be drawn from the recorded data. The winsA and winsB counters are both zero, indicating no measured victories in any workload category.

What the data does provide is a set of theoretical peak rates derived from the clock speeds and unit counts. The NVIDIA N1X 48SM shows a pixel rate of 112.6 GPixel/s, which is 8.8 times higher than Intel’s 12.80 GPixel/s. The texture rate for NVIDIA is 900.9 GTexel/s, compared to Intel’s 25.60 GTexel/s, a 35.2-fold difference. In floating-point compute, NVIDIA delivers 28.83 TFLOPS for FP32, while Intel manages 819.2 GFLOPS, or 0.819 TFLOPS, meaning NVIDIA is roughly 35.2 times faster in FP32. For FP16, NVIDIA also lists 28.83 TFLOPS with a 1:1 ratio, while Intel reaches 1.638 TFLOPS with a 2:1 ratio, making NVIDIA 17.6 times faster.

These numbers represent peak theoretical throughput, not real-world benchmark results. The absence of actual benchmark data means the database cannot confirm how these theoretical rates translate into application performance. However, the magnitude of difference in raw compute rates is substantial, and the recorded specifications align with that gap. NVIDIA’s shading units number 6144 versus Intel’s 256, a 24-fold increase. Texture mapping units are 384 versus 16, 24 times more, and render output units are 48 versus 8, 6 times more. Each of these unit counts feeds directly into the pixel, texture, and FP32 rates listed above.

The Verdict

From the recorded data alone, the NVIDIA N1X 48SM holds a commanding lead in every measurable compute category. The FP32 throughput of 28.83 TFLOPS dwarfs Intel’s 819.2 GFLOPS. The pixel rate and texture rate advantages are similarly lopsided. For workloads that rely on raw shading, texturing, or pixel output, the database indicates NVIDIA’s part is in a different performance class.

Intel’s UHD Graphics 770 Mobile does have a clear advantage in API support. The database lists DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4 for Intel. NVIDIA’s part lists DirectX as N/A, OpenGL as N/A, and Vulkan as N/A. That means for software that depends on these standard graphics APIs, Intel’s part has documented compatibility while NVIDIA’s does not. The NVIDIA part may rely on proprietary or alternative interfaces, but the database provides no such details.

The choice between these two depends on the priority. For raw compute and memory bandwidth, NVIDIA is the clear pick. For standard API compatibility, Intel is the only option with recorded support. Neither part has benchmark scores, so any verdict beyond these specification-based conclusions is unsupported by the database.

Architecture Differences

The two GPUs come from different architectural generations. Intel uses Generation 12.2, which is part of the HD Graphics-M line for Raptor Lake. NVIDIA uses Blackwell 2.0, labeled as Blackwell IGP (N1x). The process node differs: Intel is on 10 nm from its own foundry, while NVIDIA is on 5 nm from TSMC. The database lists NVIDIA’s die size as 382 mm², while Intel’s die size is not recorded. Transistor counts are unknown for Intel and listed as unknown for NVIDIA as well.

The memory architecture is a major division. Intel uses system shared memory, with type, bus width, and bandwidth all marked as system dependent. NVIDIA uses 128 GB of LPDDR5X memory on a 256-bit bus, with a bandwidth of 273.2 GB/s. The memory clock for NVIDIA is listed as 1067 MHz with 8.5 Gbps effective, while Intel’s memory clock is simply system shared. This gives NVIDIA a dedicated, high-bandwidth memory pool versus Intel’s reliance on shared system memory.

Compute resources differ structurally. Intel has 256 shading units, 16 TMUs, and 8 ROPs, with no ray tracing cores and no tensor cores. NVIDIA has 6144 shading units, 384 TMUs, 48 ROPs, 48 ray tracing cores, and 192 tensor cores. The presence of ray tracing and tensor cores on NVIDIA’s part indicates hardware support for those workloads, while Intel’s part has none. The bus interface also differs: Intel uses a Ring Bus, while NVIDIA uses PCIe 5.0 x16. Display outputs are portable device dependent for Intel, while NVIDIA lists 1x HDMI.

Clock speeds show a different strategy. Intel has a base clock of 300 MHz and a boost of 1600 MHz. NVIDIA has a base of 741 MHz and a boost of 2346 MHz. NVIDIA’s clocks are higher at both ends, and the boost is 46.6% above Intel’s. The power characteristics are less clear: Intel lists a TDP of 15 W, while NVIDIA lists TDP as unknown. Both are IGP slot width, meaning integrated graphics packages.

Where Each One Wins

The NVIDIA N1X 48SM wins in every raw throughput category in the database. The FP32 rate of 28.83 TFLOPS versus 819.2 GFLOPS puts NVIDIA ahead for general compute tasks. The pixel rate of 112.6 GPixel/s versus 12.80 GPixel/s indicates NVIDIA is stronger for fill-rate-bound work. The texture rate of 900.9 GTexel/s versus 25.60 GTexel/s shows NVIDIA dominates texturing. The 48 ray tracing cores and 192 tensor cores give NVIDIA hardware support for ray tracing and tensor operations, both absent from Intel’s part. NVIDIA also has dedicated memory with 273.2 GB/s bandwidth, while Intel’s bandwidth is system dependent.

The Intel UHD Graphics 770 Mobile wins in API compatibility. It supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4, all of which are listed as N/A for NVIDIA. For software that requires any of these standard APIs, Intel’s part has documented support. Intel also has a lower TDP at 15 W, while NVIDIA’s TDP is unknown, which may imply lower power draw for Intel, but the database does not confirm NVIDIA’s value. Intel’s base clock of 300 MHz is also lower than NVIDIA’s 741 MHz, but that does not constitute a win; it is simply a recorded difference.

The release dates also differ, with Intel available since January 2023 and NVIDIA scheduled for May 2026. For immediate availability, Intel is the only option. NVIDIA’s part is listed as active but has a future release date, so it is not yet obtainable. The bus interface differs as well: Intel uses Ring Bus, while NVIDIA uses PCIe 5.0 x16, which may affect system integration, but the database provides no performance implications.

The database also lists NVIDIA with a transistor count of unknown and Intel with no transistor count. Intel’s slot width is IGP, and NVIDIA’s slot width is also IGP. Both have no launch MSRP recorded. Both are marked as active production status. The shading unit count difference of 24 to 1 aligns with the FP32 difference of 35.2 to 1, suggesting efficiency differences, but the database offers no further data to explore that. The memory bandwidth gap of 273.2 GB/s versus system dependent means NVIDIA has a fixed, high-bandwidth path, while Intel’s performance depends on the host system’s memory configuration.
