A: The NVIDIA GeForce RTX 5090 SE includes 110 ray tracing cores and 440 tensor cores, indicating dedicated hardware for those workloads. The Intel UHD Graphics 770 Mobile lists no ray tracing cores and no tensor cores in the database, so it relies entirely on its 256 shading units for all compute tasks.

Q: What is the power consumption difference?

A: The Intel UHD Graphics 770 Mobile has a TDP of 15 W, making it suitable for portable devices. The NVIDIA GeForce RTX 5090 SE has a TDP of 500 W, with a suggested power supply of 900 W and a single 16-pin power connector. This represents a 485 W difference in thermal design power.

Architecture Differences

The architectural gap between these two GPUs is fundamental. The Intel UHD Graphics 770 Mobile belongs to Generation 12.2, built on Intel's 10 nm process node, and is integrated into the Raptor Lake mobile platform. It uses a Ring Bus interface for data movement and has no discrete memory of its own, relying on the system's shared memory for both storage and bandwidth. The 256 shading units, 16 texture mapping units, and 8 raster output pipelines form a modest execution engine designed for low-power integrated graphics duties. The absence of dedicated ray tracing cores and tensor cores confirms that this is not a compute-oriented part.

The NVIDIA GeForce RTX 5090 SE, in contrast, is built on the Blackwell 2.0 architecture using TSMC's 5 nm process. The chip, designated GB202, contains 92,200 million transistors on a 750 mm² die, yielding a transistor density of 122.9M per mm². This is a discrete card with a full complement of dedicated hardware: 14,080 shading units, 440 texture mapping units, 160 raster output pipelines, 110 ray tracing cores, and 440 tensor cores. The memory subsystem is entirely separate, with 24 GB of GDDR7 on a 384-bit bus delivering 1.34 TB/s of bandwidth.

The process technology difference is significant. Intel's 10 nm node is an older generation compared to TSMC's 5 nm process, which directly affects transistor density and power efficiency. The NVIDIA part's transistor density of 122.9M per mm² contrasts with the Intel part, for which the database lists no transistor count or die size. The 5 nm process enables the enormous shader count and clock speeds of the RTX 5090 SE within a 750 mm² die.

Feature support also differs at the API level. The Intel part supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The NVIDIA card supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The DirectX 12 Ultimate designation indicates support for advanced features like ray tracing and mesh shaders at the API level, which align with the dedicated ray tracing cores present in the NVIDIA hardware.

The NVIDIA card uses a PCIe 5.0 x16 bus interface, while the Intel IGP communicates over a Ring Bus internal to the processor. This reflects the fundamental difference between a discrete expansion card and an integrated graphics solution. The NVIDIA card's dual-slot form factor, measuring 267 mm in length, 111 mm in height, and 40 mm in width, contrasts with the Intel part's IGP classification, which requires no separate physical space.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark runs for these two parts, and neither has an average benchmark score or a wins tally in the head-to-head section. However, the theoretical peak specifications provide a clear basis for comparing their execution capabilities.

In pixel throughput, the NVIDIA GeForce RTX 5090 SE achieves 380.3 GPixel/s, while the Intel UHD Graphics 770 Mobile manages 12.80 GPixel/s. This means the NVIDIA card processes approximately 29.7 times as many pixels per second. For texture operations, the NVIDIA part delivers 1,045.9 GTexel/s against the Intel part's 25.60 GTexel/s, a factor of roughly 40.9 times.

The FP32 compute comparison shows the NVIDIA card at 66.94 TFLOPS versus the Intel part at 819.2 GFLOPS. This is a multiplier of approximately 81.7. For FP16 operations, the NVIDIA card maintains 66.94 TFLOPS with a 1:1 ratio, while the Intel part achieves 1.638 TFLOPS with a 2:1 ratio, meaning the NVIDIA card provides roughly 40.9 times the half-precision throughput.

Clock speeds show the NVIDIA part operating at a 1740 MHz base and 2377 MHz boost, compared to the Intel part's 300 MHz base and 1600 MHz boost. Despite the higher clocks, the NVIDIA card's advantage comes primarily from its massive parallel resources: 14,080 shading units versus 256, 440 texture mapping units versus 16, and 160 raster output pipelines versus 8.

Memory bandwidth is another categorical win for the NVIDIA card. Its 1.34 TB/s of dedicated GDDR7 bandwidth stands against the Intel part's "System Dependent" bandwidth, which is shared with the CPU and limited by the host platform's memory configuration. In any realistic scenario, the dedicated 384-bit bus with 28 Gbps effective memory speed gives the NVIDIA card a decisive advantage in memory-bound workloads.

The Intel part's advantages are limited to power consumption and integration. At 15 W TDP, it draws a fraction of the NVIDIA card's 500 W TDP. It also requires no additional power connectors, no suggested power supply, and occupies no expansion slot. These are not performance advantages but operational characteristics that suit different deployment scenarios.

The Verdict

The data indicates two products with entirely different purposes. The Intel UHD Graphics 770 Mobile is an integrated graphics solution with a 15 W TDP, designed for portable devices where power efficiency and minimal physical footprint take precedence. Its 256 shading units, system-shared memory, and absence of dedicated ray tracing or tensor hardware position it for basic display output, media playback, and light graphical workloads. The 50th percentile ranking against all GPUs, combined with no recorded benchmark scores, suggests it occupies a middle ground among integrated solutions but offers no pretense of high-end compute capability.

The NVIDIA GeForce RTX 5090 SE is a high-end discrete graphics card with a 500 W TDP, 24 GB of dedicated GDDR7 memory, and a full suite of modern GPU features including 110 ray tracing cores and 440 tensor cores. Its 66.94 TFLOPS FP32 performance, 380.3 GPixel/s pixel rate, and 1.34 TB/s memory bandwidth place it in an entirely different performance class. The DirectX 12 Ultimate support, PCIe 5.0 x16 interface, and dedicated display outputs for HDMI 2.1b and DisplayPort 2.1b confirm its positioning for demanding gaming and professional workloads.

Users requiring a graphics solution for a portable device with minimal power draw and no expansion slot should select the Intel UHD Graphics 770 Mobile. The 15 W TDP and IGP form factor make it suitable for thin-and-light laptops where battery life and thermal constraints are primary concerns. The system-shared memory approach eliminates the need for separate VRAM allocation, and the Ring Bus interface integrates directly with the host processor.

Users requiring maximum graphics throughput, dedicated memory, and advanced feature support should select the NVIDIA GeForce RTX 5090 SE. The 24 GB GDDR7 memory, 1.34 TB/s bandwidth, and 66.94 TFLOPS FP32 performance are categorically superior to the Intel part. The presence of ray tracing cores and tensor cores enables workloads that the Intel part cannot accelerate. The dual-slot form factor, 267 mm length, and 900 W suggested power supply indicate a desktop-class system with adequate cooling and power delivery. The launch MSRP of 1,499 USD reflects its high-end positioning.

The benchmark database shows no direct performance comparisons between these parts, but the specification data alone establishes a clear hierarchy. The NVIDIA card outperforms the Intel IGP in every measurable compute metric by factors ranging from approximately 29.7 times in pixel rate to roughly 81.7 times in FP32 throughput. The Intel part's only advantages are its 15 W TDP, its IGP form factor requiring no additional space, and its earlier release date. For any performance-sensitive application, the RTX 5090 SE is the only viable choice. For power-constrained portable applications, the UHD Graphics 770 Mobile serves a purpose that the RTX 5090 SE cannot fulfill due to its 500 W power requirement and physical dimensions.
