Intel UHD Graphics 770 Mobile vs NVIDIA Rubin GPU Comparison

Head-to-Head Benchmarks

The recorded data contains no direct benchmark comparisons between the Intel UHD Graphics 770 Mobile and the NVIDIA Rubin GPU. Both products sit at the 50th percentile versus all GPUs in the database, and neither has an average benchmark score recorded. This absence of head-to-head measurements makes a direct performance comparison impossible from the available data.

What can be stated is the theoretical peak throughput each part is specified to deliver. The NVIDIA Rubin GPU shows 130.0 TFLOPS of FP32 compute, while the Intel UHD Graphics 770 Mobile shows 819.2 GFLOPS. The Rubin part also lists a texture rate of 2,031.2 GTexel/s versus 25.60 GTexel/s for the Intel integrated solution. Pixel rate figures are 54.41 GPixel/s and 12.80 GPixel/s respectively.

The Rubin GPU's memory bandwidth is listed at 22.1 TB/s, whereas the Intel part's bandwidth is described as "System Dependent" with shared system memory. In every recorded throughput metric, the Rubin GPU holds a substantial numerical advantage.

However, these are different product classes. The Intel UHD Graphics 770 Mobile is an integrated graphics processor inside a Raptor Lake mobile chip, designed for portable systems. The NVIDIA Rubin GPU is a server-class SXM Module with a 2300 W TDP. Direct benchmark comparisons would require workloads appropriate to each platform, and none are present in the database.

The Verdict

The data does not support a meaningful performance comparison between these two products. The Intel UHD Graphics 770 Mobile is an integrated graphics solution for mobile processors, with a 15 W TDP and system-shared memory. The NVIDIA Rubin GPU is a server accelerator with a 2300 W TDP, 288 GB of HBM4, and a 1456 mm² die.

The recorded specifications show the NVIDIA part with dramatically higher compute, texture, pixel, and memory throughput. Its FP32 figure of 130.0 TFLOPS dwarfs the 819.2 GFLOPS of the Intel part. Its FP16 performance of 260.0 TFLOPS compares to 1.638 TFLOPS for the Intel IGP.

Neither part has benchmark scores or head-to-head measurements in the database. Both share a 50th percentile ranking versus all GPUs, but this reflects absence of data rather than comparable performance.

The Intel UHD Graphics 770 Mobile is appropriate for portable devices that need basic display output and light graphics acceleration without discrete hardware. The NVIDIA Rubin GPU targets server workloads requiring massive parallel compute and memory bandwidth, with no display capabilities whatsoever.

For a user building a thin-and-light laptop, the Intel part is the relevant choice. For a data center deployment requiring high-throughput compute, the NVIDIA part is the relevant choice. These products do not compete in the same market segment, and the database contains no evidence that would position them as alternatives to each other.

Where Each One Wins

The Intel UHD Graphics 770 Mobile wins on power efficiency and integration. Its 15 W TDP is suitable for battery-powered portable devices. It is an IGP, meaning it requires no separate card slot, power connectors, or cooling beyond what the host laptop provides. It supports display outputs (portable device dependent), which the NVIDIA part completely lacks. The Intel part also supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4, making it usable for consumer graphics applications.

The NVIDIA Rubin GPU wins on raw compute and memory capacity. Its 130.0 TFLOPS FP32, 260.0 TFLOPS FP16, 2,031.2 GTexel/s texture rate, and 54.41 GPixel/s pixel rate are orders of magnitude beyond the Intel part. The 288 GB HBM4 memory with 22.1 TB/s bandwidth provides a scale of data handling that system-shared memory cannot approach. The 896 tensor cores give it dedicated hardware for matrix operations, a feature absent from the Intel IGP entirely.

The NVIDIA part also uses a newer 3 nm process from TSMC versus Intel's 10 nm node, and its 336,000 million transistor count on a 1456 mm² die indicates a far more complex chip. Its PCIe 6.0 x16 interface provides a high-bandwidth connection to the host system, versus the Ring Bus interface of the integrated Intel graphics.

The Intel part has a release date of 2023-01-03, meaning it has been available for some time. The NVIDIA Rubin GPU is dated 2025-12-31, positioning it as a next-generation server product. The Intel part's successor is Arc Graphics-M, while the NVIDIA part has no successor listed, indicating it is the latest in its line.

In practical terms, the Intel UHD Graphics 770 Mobile wins in any scenario requiring a compact, low-power integrated solution for a laptop. The NVIDIA Rubin GPU wins in any scenario requiring maximum throughput for server-side computation, where power consumption and physical size are secondary considerations. The database contains no workload where these two parts would be interchangeable.
