The Verdict

The recorded data presents a stark performance hierarchy. The Intel UHD Graphics 770 Mobile is positioned as a basic integrated graphics solution with a 50th percentile ranking and zero benchmark entries. The NVIDIA GeForce RTX 5070 Mobile, with its 75th percentile ranking and an average benchmark score of 29,928, occupies a completely different tier. Systems requiring substantial GPU compute, such as those running DirectX 12 workloads or OpenCL applications, should select the RTX 5070 Mobile without hesitation based on the benchmark evidence.

The RTX 5070 Mobile's nearest rivals, all desktop-class GPUs from previous generations, cluster within a narrow 1.7% band. This indicates the mobile part delivers performance comparable to established desktop cards like the RTX 3070 Ti and RX 6800. The Intel part has no comparable data, making any performance-based justification for its selection impossible. The only scenario favoring the Intel solution is one where the 15 W TDP is mandatory for thermal or power constraints, as the RTX 5070 Mobile demands 50 W.

Head-to-Head Benchmarks

Direct head-to-head benchmark results between the two parts are absent from the database. However, the available measurements for the NVIDIA GeForce RTX 5070 Mobile provide a clear picture of its capabilities. In Geekbench OpenCL, it scores 122,238, and in Geekbench Vulkan, it reaches 116,960. Passmark results show 20,355 in G3D, 8,279 in GPU Compute, 896 in G2D, and legacy DirectX scores of 214 (DX9), 192 (DX11), 129 (DX10), and 93 (DX12).

The Intel UHD Graphics 770 Mobile has no recorded scores in any of these tests. Its theoretical peak rates from the specification sheet, 12.80 GPixel/s pixel fill and 25.60 GTexel/s texture fill, compare to the NVIDIA part's 68.40 GPixel/s and 205.2 GTexel/s. The RTX 5070 Mobile delivers 5.3 times the pixel rate and 8.0 times the texture rate of the Intel solution. In raw floating-point throughput, the NVIDIA GPU's 13.13 TFLOPS FP32 dwarfs the Intel's 819.2 GFLOPS, a 16-fold advantage. These ratios, derived strictly from the recorded specification data, illustrate the magnitude of the performance gap.

The RTX 5070 Mobile's 36 ray tracing cores and 144 tensor cores provide hardware acceleration that the Intel UHD Graphics 770 Mobile lacks entirely, as it lists no such units. The average benchmark score of 29,928 places the NVIDIA part within 0.1% of the RTX 3070 Ti (29,945), indicating parity with that previous-generation desktop flagship. The closest recorded rival, the RTX 2080 Ti, trails by 0.5%, meaning the mobile RTX 5070 exceeds a desktop card that was once the fastest consumer GPU available.

Specification Differences

The two GPUs differ across nearly every measurable specification. The Intel UHD Graphics 770 Mobile uses a Raptor Lake chip built on Intel's 10 nm process, while the NVIDIA GeForce RTX 5070 Mobile uses the GB206 chip on TSMC's 5 nm node. The NVIDIA die measures 181 mm² and contains 21,900 million transistors, figures absent for the Intel part.

Clock speeds diverge sharply. The Intel part runs at a 300 MHz base and 1600 MHz boost. The NVIDIA part starts at 907 MHz base and boosts to 1425 MHz. Despite the lower boost clock, the NVIDIA GPU's massively larger execution resources deliver far greater throughput.

Compute unit counts show the architectural gulf. The Intel UHD Graphics 770 Mobile has 256 shading units, 16 texture mapping units, and 8 raster output units. The RTX 5070 Mobile has 4,608 shading units, 144 TMUs, and 48 ROPs. That is 18 times more shaders, 9 times more TMUs, and 6 times more ROPs. The NVIDIA part also adds 36 dedicated ray tracing cores and 144 tensor cores, features entirely absent from the Intel design.

Memory systems are fundamentally different. The Intel GPU shares system memory with an unspecified type and bus width, and its bandwidth is system dependent. The NVIDIA GPU uses dedicated 8 GB GDDR7 on a 128-bit interface with a fixed 384.0 GB/s bandwidth. Memory clock reads 1500 MHz with 24 Gbps effective transfer for the NVIDIA part, versus a system-shared configuration for Intel.

The bus interface differs: Intel uses a Ring Bus, NVIDIA uses PCIe 5.0 x16. TDP figures are 15 W for Intel and 50 W for NVIDIA. Both share the same IGP slot width and portable-device-dependent display outputs. The NVIDIA part lists no power connectors, and neither has a launch MSRP recorded.

Architecture Differences

The Intel UHD Graphics 770 Mobile belongs to the HD Graphics-M generation under the Raptor Lake codename, built on Generation 12.2 architecture. It succeeds no listed predecessor and has a successor in Arc Graphics-M. The NVIDIA GeForce RTX 5070 Mobile belongs to the GeForce 50-series using Blackwell 2.0 architecture, with GB206 as its chip, and lists GeForce 40 Mobile as its predecessor.

Process technology separates the designs by a full node generation. Intel fabricates on 10 nm at its own foundry. NVIDIA uses TSMC's 5 nm process. The transistor density of the GB206 chip, 121.0M per mm², reflects the more advanced fabrication, while the Intel chip's density remains unrecorded.

The compute architecture differs in fundamental organization. Intel's Generation 12.2 provides 256 shaders in a configuration suited to low-power integrated graphics. NVIDIA's Blackwell 2.0 deploys 4,608 shaders alongside dedicated ray tracing and tensor hardware. The FP16 capability highlights the design philosophy difference: Intel delivers 1.638 TFLOPS FP16 at a 2:1 ratio relative to FP32, while NVIDIA matches FP16 to FP32 at 13.13 TFLOPS with a 1:1 ratio. NVIDIA's approach provides consistent throughput across precision formats, useful for machine learning and compute workloads.

API support reflects the generation gap. Intel reaches DirectX 12 (12_1), while NVIDIA supports DirectX 12 Ultimate (12_2), enabling additional hardware features in the newer API tier. OpenGL 4.6 and Vulkan 1.4 are common to both. The presence of 144 tensor cores in the NVIDIA design enables AI-accelerated features, while the Intel part has no equivalent units. Ray tracing, handled by 36 dedicated cores in the NVIDIA GPU, is completely absent from the Intel architecture. These architectural disparities, combined with the 16-fold FP32 throughput difference, explain the performance positioning recorded in the database.
