Intel UHD Graphics 770 Mobile vs NVIDIA GeForce RTX 4070 AD103 Comparison

Head-to-Head Benchmarks

The database shows no direct head-to-head benchmark results between the Intel UHD Graphics 770 Mobile and the NVIDIA GeForce RTX 4070 AD103. This is expected given the fundamental positioning of these two parts. The integrated graphics solution from Intel is designed for basic display output and light workloads, while the NVIDIA discrete GPU targets high-performance gaming and compute tasks. Without recorded comparative scores, the analysis must rely on the raw specification data and architectural differences to project relative performance.

The Intel UHD Graphics 770 Mobile delivers a pixel rate of 12.80 GPixel/s and a texture rate of 25.60 GTexel/s. Its floating-point performance measures 819.2 GFLOPS for FP32 and 1.638 TFLOPS for FP16 with a 2:1 ratio. The NVIDIA GeForce RTX 4070 AD103, by contrast, reaches 158.4 GPixel/s, 455.4 GTexel/s, and 29.15 TFLOPS for both FP32 and FP16 at a 1:1 ratio. These figures indicate the discrete GPU holds a 12.4x advantage in pixel throughput, a 17.8x advantage in texture throughput, and a 35.6x advantage in FP32 compute. The FP16 comparison is even more lopsided: the RTX 4070 AD103 delivers 29.15 TFLOPS versus the Intel part's 1.638 TFLOPS, a 17.8x gap.

Memory bandwidth further separates the two. The Intel UHD Graphics 770 Mobile uses system shared memory with bandwidth described as system dependent, meaning its performance scales with the host platform's RAM configuration. The RTX 4070 AD103 uses 12 GB of GDDR6X on a 192-bit bus, delivering 504.2 GB/s of dedicated bandwidth. This dedicated memory eliminates contention with the CPU and provides a stable, high-throughput foundation for texture streaming and frame buffer operations.

Clock speeds tell a similar story. The Intel part operates at a 300 MHz base and 1600 MHz boost. The NVIDIA GPU runs at 1920 MHz base and 2475 MHz boost. Higher clocks alone do not explain the full performance delta, but combined with the massive differences in shading units (256 versus 5888), texture mapping units (16 versus 184), and render output units (8 versus 64), the architectural gap becomes clear.

The Verdict

The data indicates two entirely different product categories. The Intel UHD Graphics 770 Mobile is an integrated graphics processor (IGP) with a 15 W TDP, designed for portable devices where power efficiency and minimal space take priority. The NVIDIA GeForce RTX 4070 AD103 is a dual-slot discrete graphics card with a 200 W TDP, requiring a 550 W suggested power supply and a 16-pin power connector. It measures 240 mm in length, 110 mm in height, and 40 mm in width. These physical and power characteristics alone dictate their use cases.

For workloads involving real-time ray tracing, the RTX 4070 AD103 includes 46 dedicated RT cores, a feature entirely absent from the Intel IGP. Similarly, the NVIDIA part integrates 184 tensor cores for AI-accelerated tasks, while the Intel part lists none. The RTX 4070 AD103 supports DirectX 12 Ultimate (12_2), whereas the Intel part supports DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4, so API-level compatibility for those standards matches.

The production status differs as well. The Intel UHD Graphics 770 Mobile remains active in production, while the RTX 4070 AD103 is end-of-life, with the GeForce 50 series listed as its successor. Release dates show the Intel part launched on January 3, 2023, and the NVIDIA part on February 29, 2024. The RTX 4070 AD103 has a launch MSRP of 599 USD, though pricing considerations are secondary to its technical capabilities.

Architecture Differences

The Intel UHD Graphics 770 Mobile uses the Raptor Lake chip with a Generation 12.2 architecture, built on Intel's 10 nm process. It employs a ring bus interface and integrates 256 shading units, 16 TMUs, and 8 ROPs. The architecture lacks dedicated RT cores and tensor cores, relying entirely on its unified shader array for all graphics and compute workloads. Its memory subsystem is system shared, meaning it draws from the host's main memory with no dedicated VRAM. The pixel rate of 12.80 GPixel/s and texture rate of 25.60 GTexel/s reflect a design optimized for basic 2D and light 3D rendering, not high-end gaming.

The NVIDIA GeForce RTX 4070 AD103 uses the AD103 chip with an Ada Lovelace architecture, fabricated on TSMC's 5 nm process. The die contains 45,900 million transistors across a 379 mm² area, yielding a transistor density of 121.1M per mm². This process advantage allows for 5,888 shading units, 184 TMUs, and 64 ROPs, along with the 46 RT cores and 184 tensor cores. The memory interface uses a 192-bit bus connected to 12 GB of GDDR6X running at 1313 MHz (21 Gbps effective), producing 504.2 GB/s bandwidth. The bus interface is PCIe 4.0 x16, a standard external connection, versus the Intel part's ring bus, which ties it directly to the CPU's internal fabric.

The FP16 capability highlights a key architectural divergence. The Intel part achieves 1.638 TFLOPS at a 2:1 ratio relative to its FP32 throughput, indicating it halves the rate for half-precision work. The NVIDIA part achieves 29.15 TFLOPS at a 1:1 ratio, meaning it processes FP16 at the same rate as FP32. This suggests the Ada Lovelace architecture handles mixed-precision workloads without penalty, a feature relevant for AI inference and certain scientific computations.

Where Each One Wins

The Intel UHD Graphics 770 Mobile wins in power efficiency and integration. Its 15 W TDP makes it suitable for portable devices where battery life and thermal management are critical. As an IGP with a ring bus interface, it requires no additional board space, no power connectors, and no discrete cooling solution. Its system shared memory approach means there is no dedicated VRAM cost, and the design scales with the host platform's memory bandwidth. For basic desktop compositing, video playback, and light productivity applications, this integrated solution provides adequate performance within a minimal power envelope. Its active production status suggests continued relevance in low-power systems.

The NVIDIA GeForce RTX 4070 AD103 wins in every measurable performance category. Its 29.15 TFLOPS FP32 throughput, 504.2 GB/s memory bandwidth, and dedicated RT and tensor cores position it for high-refresh-rate gaming, 3D rendering, and AI workloads. The 12 GB GDDR6X frame buffer supports large textures and complex scenes without spilling to system memory. The PCIe 4.0 x16 interface provides high-bandwidth communication with the host CPU. Its 200 W TDP and dual-slot design indicate a requirement for robust cooling and power delivery, but the performance ceiling is correspondingly higher. The 46 RT cores enable hardware-accelerated ray tracing, while the 184 tensor cores accelerate DLSS-style upscaling and other neural network operations.

The architectural split could not be starker. The Intel part uses 256 shading units, 16 TMUs, and 8 ROPs, a configuration suitable for 1080p at low settings in older titles or integrated graphics gaming. The NVIDIA part uses 5,888 shading units, 184 TMUs, and 64 ROPs, a configuration designed for 4K gaming and professional workloads. The pixel rate difference of 12.80 GPixel/s versus 158.4 GPixel/s means the RTX 4070 AD103 can fill frames at over twelve times the rate, while the texture rate difference of 25.60 GTexel/s versus 455.4 GTexel/s indicates nearly eighteen times the texture processing capacity.
