Intel UHD Graphics 770 Mobile vs NVIDIA GeForce RTX 5080 SUPER Comparison

# Intel UHD Graphics 770 Mobile vs NVIDIA GeForce RTX 5080 SUPER

The Intel UHD Graphics 770 Mobile and the NVIDIA GeForce RTX 5080 SUPER occupy opposite ends of the GPU spectrum. The Intel part is an integrated graphics solution for mobile processors, while the NVIDIA part is a discrete, high-performance desktop graphics card. The recorded data shows a massive gap in every measurable performance category, with the RTX 5080 SUPER delivering over two orders of magnitude more compute throughput and memory bandwidth than the Intel UHD Graphics 770 Mobile.

Where Each One Wins

The Intel UHD Graphics 770 Mobile wins in power efficiency and physical integration. It carries a 15 W TDP, which makes it suitable for thin-and-light portable devices where battery life and thermal management are primary concerns. The Intel part is an IGP (integrated graphics processor) with a Ring Bus interface, meaning it shares system memory and requires no dedicated power connectors. Its display outputs are portable device dependent, so it adapts to whatever panel and video outputs the host laptop provides. For basic desktop rendering, video playback, and light productivity tasks, the Intel UHD Graphics 770 Mobile is the only viable option in this comparison because it is built into the processor itself.

The NVIDIA GeForce RTX 5080 SUPER wins in every performance metric. It is a dual-slot, 304 mm long, 137 mm tall, 40 mm thick expansion card that requires a PCIe 5.0 x16 slot and a single 16-pin power connector. It uses 24 GB of GDDR7 memory on a 256-bit bus, delivering 1.02 TB/s of bandwidth, compared to the Intel part's system-shared memory with system-dependent bandwidth. The RTX 5080 SUPER has 10752 shading units, 336 texture mapping units, 112 raster operation units, 84 ray tracing cores, and 336 tensor cores. The Intel UHD Graphics 770 Mobile has 256 shading units, 16 TMUs, and 8 ROPs, with no ray tracing or tensor cores. The RTX 5080 SUPER produces 293.1 GPixel/s of pixel rate and 879.3 GTexel/s of texture rate, versus 12.80 GPixel/s and 25.60 GTexel/s for the Intel part. The NVIDIA card also supports DirectX 12 Ultimate (12_2), while the Intel part supports DirectX 12 (12_1). For gaming, 3D rendering, machine learning, and high-resolution video processing, the RTX 5080 SUPER is the clear winner.

Architecture Differences

The Intel UHD Graphics 770 Mobile is built on Intel's Generation 12.2 architecture, specifically the HD Graphics-M generation for Raptor Lake. It uses a 10 nm process node manufactured by Intel's own foundry. The architecture is a classic integrated design with 256 shading units, 16 TMUs, and 8 ROPs, arranged to provide basic graphics acceleration for mobile processors. The chip runs at a base clock of 300 MHz and a boost clock of 1600 MHz. Its memory subsystem is entirely system-shared, meaning it borrows from the host system's RAM, and bandwidth is system dependent. The FP32 throughput is 819.2 GFLOPS, and FP16 throughput is 1.638 TFLOPS with a 2:1 ratio. The Intel part uses a Ring Bus interface, which is a low-latency interconnect typical of integrated processors. It supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4.

The NVIDIA GeForce RTX 5080 SUPER is built on the Blackwell 2.0 architecture, part of the GeForce 50-series generation. It uses the GB203 chip fabricated on a 5 nm process node at TSMC. The chip contains 45,600 million transistors on a 378 mm² die, resulting in a transistor density of 120.6M per mm². The GPU has 10,752 shading units, 336 TMUs, and 112 ROPs, along with 84 dedicated ray tracing cores and 336 tensor cores. Base clock is 2295 MHz with a boost clock of 2617 MHz. Memory is 24 GB of GDDR7 on a 256-bit bus, running at 2000 MHz with 32 Gbps effective speed, yielding 1.02 TB/s of bandwidth. FP32 and FP16 throughput are both 56.28 TFLOPS with a 1:1 ratio, indicating full-rate FP16 execution. The card connects via PCIe 5.0 x16 and supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The architectural differences are stark: the RTX 5080 SUPER has dedicated hardware for ray tracing and tensor operations, while the Intel part has none. The NVIDIA card's 5 nm process node at TSMC is smaller than Intel's 10 nm node, allowing for far greater transistor density and clock speeds. The RTX 5080 SUPER also operates at a significantly higher power envelope of 415 W, enabling its high clock rates and massive compute throughput.

Head-to-Head Benchmarks

The database contains a single benchmark entry for the RTX 5080 SUPER: 3DMark Steel Nomad DX12, where it scored 3075 points. The Intel UHD Graphics 770 Mobile has no recorded benchmark scores in the database. The RTX 5080 SUPER's average benchmark score is also 3075, placing it at the 19th percentile of all GPUs in the database. Its nearest rivals are the NVIDIA Quadro P1000 with an average score of 3163 (2.8% higher), the Intel Arc Pro B60 with 3182 (3.4% higher), the NVIDIA GeForce 820A with 2983 (3.1% lower), and the NVIDIA GeForce GTX 860M with 2967 (3.6% lower). This places the RTX 5080 SUPER in a tight cluster of mid-range performers, despite its high-end specifications.

Since the Intel UHD Graphics 770 Mobile has no benchmark data, direct numerical comparison is impossible. However, the specification differences provide clear evidence of the performance gap. The RTX 5080 SUPER's FP32 throughput of 56.28 TFLOPS is approximately 68 times higher than the Intel part's 819.2 GFLOPS. The pixel rate of 293.1 GPixel/s is roughly 23 times higher than 12.80 GPixel/s, and the texture rate of 879.3 GTexel/s is about 34 times higher than 25.60 GTexel/s. The NVIDIA card has 42 times more shading units, 21 times more TMUs, and 14 times more ROPs. Memory bandwidth of 1.02 TB/s versus system-dependent shared memory represents an enormous difference in memory throughput, which directly impacts fill-rate-bound workloads and large data transfers.

The RTX 5080 SUPER also has 84 ray tracing cores and 336 tensor cores, features entirely absent from the Intel UHD Graphics 770 Mobile. These dedicated units accelerate real-time ray tracing, DLSS-style upscaling, and AI inference workloads. The Intel part cannot execute these operations in hardware, so any ray-traced or AI-accelerated workload would either be software-emulated or unsupported.
