Specification Differences

The two parts differ across every major specification category. The NVIDIA B300 SXM6 AC uses a GB110 chip built on a 5 nm process at TSMC, containing 208,000 million transistors on a 1628 mm² die. The Intel UHD Graphics 770 Mobile uses a Raptor Lake chip on Intel's 10 nm process, with no transistor count or die size recorded.

Clock speeds diverge substantially. The NVIDIA part runs at a 1665 MHz base clock and boosts to 2032 MHz. The Intel part operates at 300 MHz base and 1600 MHz boost. Memory clocks reflect their different architectures: the B300 SXM6 AC uses 2000 MHz with 8 Gbps effective transfer, while the Intel part lists system shared memory.

The B300 SXM6 AC delivers 76.99 TFLOPS FP32 and 76.99 TFLOPS FP16 with a 1:1 ratio. The Intel UHD Graphics 770 Mobile delivers 819.2 GFLOPS FP32 and 1.638 TFLOPS FP16 with a 2:1 ratio. Pixel rate stands at 48.77 GPixel/s for NVIDIA versus 12.80 GPixel/s for Intel. Texture rate measures 1,202.9 GTexel/s versus 25.60 GTexel/s.

Power consumption reveals the intended use cases. The B300 SXM6 AC draws 1100 W and comes as an SXM Module with a suggested 1500 W power supply. The Intel part draws 15 W and ships as an IGP. The B300 SXM6 AC connects via PCIe 6.0 x16, while the Intel part uses a Ring Bus interface.

Display outputs also differ completely. The NVIDIA B300 SXM6 AC has no display outputs, while the Intel UHD Graphics 770 Mobile provides outputs described as portable device dependent. The NVIDIA part targets server deployment, confirmed by its Server Blackwell generation and SXM form factor.

Architecture Differences

The NVIDIA B300 SXM6 AC belongs to the Blackwell Ultra architecture, built on the GB110 chip. Its generation is listed as Server Blackwell (Bxx), and it succeeds the Server Hopper line while being succeeded by Server Rubin. The Intel UHD Graphics 770 Mobile uses Generation 12.2 architecture on the Raptor Lake chip, listed under HD Graphics-M (Raptor Lake), with the Arc Graphics-M as its successor.

Process technology separates the two fundamentally. NVIDIA uses TSMC's 5 nm node, while Intel uses its own 10 nm process. The transistor count of 208,000 million for the B300 SXM6 AC produces a density of 127.8 million transistors per square millimeter across the 1628 mm² die. Intel's part has no transistor data recorded.

Compute resources show the scale difference. The B300 SXM6 AC packs 18,944 shading units, 592 TMUs, 24 ROPs, and 592 tensor cores. The Intel UHD Graphics 770 Mobile contains 256 shading units, 16 TMUs, and 8 ROPs, with no tensor cores. The B300 SXM6 AC also supports FP16 at full rate (1:1), while Intel uses a 2:1 ratio, halving throughput for half-precision work.

Memory architecture could not differ more. NVIDIA uses 288 GB of HBM3e across an 8192-bit bus, achieving 8.19 TB/s bandwidth. Intel relies on system shared memory with bandwidth labeled system dependent. This means Intel's performance varies with the host system's memory subsystem, while NVIDIA's is fixed and massive.

API support separates the parts by design intent. Intel supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4, making it suitable for consumer graphics workloads. NVIDIA lists N/A for all three APIs, confirming its role as a compute accelerator rather than a graphics output device.

Production status shows both parts active, but with different release timing. Intel released on January 3, 2023. NVIDIA followed on September 10, 2025. Both remain in production.

The Verdict

The data presents two parts with no overlap in purpose or performance envelope. The NVIDIA B300 SXM6 AC dominates every recorded metric. Its OpenCL score of 369,831 places it in the 100th percentile, and it leads its nearest rival, the NVIDIA B200, by 7%. The Intel UHD Graphics 770 Mobile has no benchmark scores, placing it at the 50th percentile by default rather than by measured achievement.

For compute-heavy server workloads, the B300 SXM6 AC is the clear choice. Its 288 GB of HBM3e memory with 8.19 TB/s bandwidth, 592 tensor cores, and 76.99 TFLOPS of FP32 throughput position it for large-scale AI and data center tasks. Its 1100 W TDP and SXM module form factor confirm it belongs in dedicated server infrastructure with substantial power delivery.

For integrated graphics in portable devices, the Intel UHD Graphics 770 Mobile serves a completely different role. Its 15 W TDP, system shared memory, and portable device dependent display outputs make it suitable for basic display and light graphics duties within a laptop or compact system. Its support for DirectX 12, OpenGL 4.6, and Vulkan 1.4 enables standard consumer applications.

The specification differences reinforce this split. The B300 SXM6 AC has no display outputs, making it unsuitable for any graphics output role. The Intel part lacks tensor cores and dedicated memory, making it unsuitable for serious compute acceleration. Each part wins where the other cannot compete.

Users needing server-grade compute acceleration should select the NVIDIA B300 SXM6 AC. Users needing integrated graphics for a portable system should select the Intel UHD Graphics 770 Mobile. The database records no scenario where these parts compete directly, and the data confirms they occupy separate market segments entirely.
