Intel Iris Xe Graphics 80EU Mobile vs NVIDIA GeForce RTX 5070 Mobile Comparison

The Verdict

The data in this comparison is unambiguous. The NVIDIA GeForce RTX 5070 Mobile is in an entirely different performance class than the Intel Iris Xe Graphics 80EU Mobile. The RTX 5070 Mobile sits at the 75th percentile among all GPUs in the database, while the Iris Xe is at the 50th percentile. The RTX 5070 Mobile delivers an average benchmark score of 29,928, whereas the Iris Xe has no recorded benchmark scores in the database, meaning its average is effectively zero. For any workload that relies on GPU compute, the RTX 5070 Mobile is the only viable option between the two.

The Iris Xe is an integrated graphics processor designed for basic display output and light workloads. Its role is to provide a functional graphics experience without a dedicated card. The RTX 5070 Mobile, by contrast, is a dedicated mobile GPU with 8 GB of GDDR7 memory, 4,608 shading units, and dedicated ray tracing and tensor cores. The recorded data shows the RTX 5070 Mobile is competitive with desktop GPUs like the RTX 3070 Ti, RTX 2080 Ti, RX 6800, and RX 6700, all of which fall within a 1.7 percent delta of its average score. The Iris Xe has no such rivals listed.

Architecture Differences

The two GPUs come from different architectural generations and foundries. The Intel Iris Xe Graphics 80EU Mobile uses the Generation 12.2 architecture on a 10 nm process at Intel. Its chip is Raptor Lake, and it belongs to the HD Graphics-M generation. The NVIDIA GeForce RTX 5070 Mobile uses the Blackwell 2.0 architecture on a 5 nm process at TSMC, with the GB206 chip in the GeForce 50 Mobile generation.

The transistor counts tell a large part of the story. The RTX 5070 Mobile packs 21,900 million transistors on a 181 mm² die, giving it a transistor density of 121.0M per mm². The Iris Xe has no transistor or die size data recorded. The RTX 5070 Mobile uses 4,608 shading units, 144 texture mapping units, and 48 raster output units. It also includes 36 ray tracing cores and 144 tensor cores. The Iris Xe has 640 shading units, 40 TMUs, and 20 ROPs, with no ray tracing or tensor cores listed.

The memory subsystems are fundamentally different. The RTX 5070 Mobile has 8 GB of GDDR7 memory on a 128 bit bus, delivering 384.0 GB/s of bandwidth at 1500 MHz with 24 Gbps effective speed. The Iris Xe uses system shared memory with a system dependent bandwidth and a system shared bus width. Its memory clock is also system shared. The RTX 5070 Mobile connects via PCIe 5.0 x16, while the Iris Xe uses a Ring Bus interface.

Where Each One Wins

The RTX 5070 Mobile wins in every measurable category. Its pixel rate is 68.40 GPixel/s versus 29.00 GPixel/s for the Iris Xe. Its texture rate is 205.2 GTexel/s versus 58.00 GTexel/s. Its FP32 compute is 13.13 TFLOPS versus 1.856 TFLOPS. Its FP16 compute is 13.13 TFLOPS with a 1:1 ratio, while the Iris Xe delivers 3.712 TFLOPS with a 2:1 ratio. The RTX 5070 Mobile supports DirectX 12 Ultimate (12_2), while the Iris Xe supports DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4.

The power envelope is also different. The RTX 5070 Mobile has a 50 W TDP, while the Iris Xe has a 15 W TDP. This makes the Iris Xe far more suitable for low-power, ultraportable devices where battery life is a priority. The RTX 5070 Mobile, with its higher power draw, is for performance-oriented laptops that can manage the thermal and power requirements. The Iris Xe has no power connectors, and the RTX 5070 Mobile also lists no power connectors, relying instead on the motherboard supply.

The RTX 5070 Mobile is the clear choice for gaming, content creation, or any GPU-accelerated compute. The Iris Xe is only appropriate for basic tasks like video playback, office productivity, and light 2D graphics. The benchmark data confirms this split: the RTX 5070 Mobile scores 20,355 in PassMark G3D, 122,238 in Geekbench OpenCL, and 116,960 in Geekbench Vulkan. The Iris Xe has no recorded scores in any of these tests.

Head-to-Head Benchmarks

The database does not list any direct head-to-head benchmark results between these two GPUs, and the Iris Xe has no individual benchmark scores recorded. The comparison therefore rests on the RTX 5070 Mobile's recorded results and the architectural specifications of both parts.

The RTX 5070 Mobile's strongest recorded results are in Geekbench OpenCL with 122,238 points and Geekbench Vulkan with 116,960 points. Its PassMark G3D score is 20,355, its PassMark GPU Compute score is 8,279, and its PassMark G2D score is 896. In the older DirectX tests, it scores 214 in DirectX 9, 192 in DirectX 11, 129 in DirectX 10, and 93 in DirectX 12. These scores place it at the 75th percentile among all GPUs, with an average of 29,928.

Against its nearest rivals, the RTX 5070 Mobile's average score is nearly identical to the RTX 3070 Ti, which averages 29,945. The RTX 2080 Ti averages 29,783, the RX 6800 averages 30,095, and the RX 6700 averages 30,433. The deltas are all within 1.7 percent, which means the RTX 5070 Mobile performs at the level of these last-generation desktop cards despite being a mobile part.

The Iris Xe, by contrast, has no recorded benchmark scores. Its theoretical peak FP32 compute is 1.856 TFLOPS, which is roughly 14 percent of the RTX 5070 Mobile's 13.13 TFLOPS. Its pixel rate of 29.00 GPixel/s is less than half of the RTX 5070 Mobile's 68.40 GPixel/s, and its texture rate of 58.00 GTexel/s is less than a third of the RTX 5070 Mobile's 205.2 GTexel/s. These figures, while theoretical, confirm the massive gap in raw throughput.
