Intel UHD Graphics 770 Mobile vs NVIDIA H20 Comparison

Head-to-Head Benchmarks

The database does not contain head-to-head benchmark results for the Intel UHD Graphics 770 Mobile and the NVIDIA H20. The head-to-head benchmark table is empty, and the recorded win counts for both products are zero. Consequently, there are no direct performance scores, percentile deltas, or rival comparisons to walk through for these two GPUs.

The absence of direct measurements is itself informative. The Intel UHD Graphics 770 Mobile is an integrated graphics processor with a 15 W TDP, while the NVIDIA H20 is a server accelerator with a 500 W TDP. The difference in power envelopes and target platforms is substantial, which likely explains why no standardized head-to-head data exists in the database. Direct comparisons are typically generated for products that occupy similar market positions or performance classes.

What the database does provide are the raw architectural capabilities of each product. The NVIDIA H20 delivers a peak FP32 throughput of 39.54 TFLOPS, while the Intel UHD Graphics 770 Mobile delivers 819.2 GFLOPS. In raw compute terms, the H20 is approximately 48 times faster in FP32, though this ratio should not be mistaken for a benchmark score. The H20 also offers a texture rate of 617.8 GTexel/s versus 25.60 GTexel/s for the Intel part, and a pixel rate of 47.52 GPixel/s versus 12.80 GPixel/s.

The H20's memory subsystem is fundamentally different. It uses 96 GB of HBM3 across a 6144-bit bus, yielding 4.03 TB/s of bandwidth. The Intel UHD Graphics 770 Mobile uses system shared memory, with the bus width and bandwidth described as "System Dependent" and "System Shared" respectively. The H20's memory clock is listed at 1313 MHz with 5.3 Gbps effective data rate, while the Intel part has no dedicated memory clock because it relies on system memory.

Clock speeds also differ significantly. The Intel UHD Graphics 770 Mobile has a base clock of 300 MHz and a boost clock of 1600 MHz. The NVIDIA H20 has a base clock of 1830 MHz and a boost clock of 1980 MHz. The Intel part's lower clocks are typical for an integrated solution designed to conserve power, whereas the H20's higher clocks support its server workload orientation.

Where Each One Wins

Without benchmark scores in the database, the analysis must rely on the recorded specifications to determine where each product holds an advantage.

The Intel UHD Graphics 770 Mobile wins in integration and portability. It is classified as an IGP with a Ring Bus interface, meaning it is designed to be embedded within a processor package. Its 15 W TDP makes it suitable for mobile or low-power systems. It supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4, providing a full graphics API stack for consumer applications. Its display outputs are described as "Portable Device Dependent," indicating flexibility for laptop or mobile device integration. The production status is Active, and it was released on 2023-01-03.

The NVIDIA H20 wins in raw compute capability and memory capacity. It is built on the Hopper architecture with a GH100 chip, manufactured on a 5 nm process by TSMC. The chip contains 80,000 million transistors on an 814 mm² die, with a transistor density of 98.3M per mm². It includes 9984 shading units, 312 tensor cores, and 312 texture mapping units. The H20 is designed as an SXM Module with a PCIe 5.0 x16 bus interface. It has no display outputs, confirming its role as a compute accelerator rather than a graphics output device. Its production status is Active, and it was released on 2024-01-31.

The H20 also wins in memory technology. Its HBM3 memory with 96 GB capacity and 4.03 TB/s bandwidth is designed for data-intensive server workloads. The Intel UHD Graphics 770 Mobile's system-shared memory is inherently limited by the host system's memory bandwidth and capacity.

The Intel part wins in API compatibility for graphics workloads. The H20 has no DirectX, OpenGL, or Vulkan support recorded in the database. All three API fields are listed as "N/A" for the NVIDIA product. This indicates the H20 is not intended for traditional graphics rendering tasks that rely on these APIs.

The Verdict

The data indicates these two products serve entirely different purposes. The Intel UHD Graphics 770 Mobile is an integrated graphics solution for portable devices, with a 15 W TDP and full graphics API support. The NVIDIA H20 is a server accelerator with a 500 W TDP, 96 GB of HBM3 memory, and no display outputs or consumer graphics APIs.

The database shows no benchmark overlap, no head-to-head scores, and no rival comparisons for either product. The percentile ranking for both is 50, but this is the default value given the absence of benchmark data. The average benchmark score for both is 0.

Users seeking a low-power integrated graphics solution for a mobile device would select the Intel UHD Graphics 770 Mobile based on its architecture, TDP, and API support. Users requiring high-throughput compute for server workloads would select the NVIDIA H20 based on its FP32 throughput of 39.54 TFLOPS, FP16 throughput of 79.07 TFLOPS, and 4.03 TB/s memory bandwidth.

The NVIDIA H20's predecessor is recorded as Server Ada, and its successor is Server Blackwell. The Intel UHD Graphics 770 Mobile's successor is Arc Graphics-M. These lineage entries confirm the different product families: Intel's integrated graphics line versus NVIDIA's server compute line.

Selecting between them is a matter of platform and workload, not performance preference. The Intel part is an IGP with no power connectors and a Ring Bus interface. The NVIDIA part is an SXM Module with a suggested PSU of 900 W. These are not competing products; they are complementary components for different computing environments.
