NVIDIA GeForce RTX 5070 vs NVIDIA GeForce RTX 5070 Mobile Comparison

The Verdict

The desktop NVIDIA GeForce RTX 5070 is decisively faster than the NVIDIA GeForce RTX 5070 Mobile across every recorded benchmark. The head-to-head data shows the desktop part winning all nine tests, with deltas ranging from 16.1% in PassMark DirectX 12 to a massive 90.7% in PassMark GPU Compute. The average benchmark score tells the same story: the desktop card averages 40,377 points versus 29,928 for the mobile chip, a gap of roughly 35%. The desktop GPU also sits at the 82nd percentile among all GPUs in the database, while the mobile part lands at the 75th percentile.

Benchmark results indicate the desktop RTX 5070 should be the choice for anyone prioritizing raw compute throughput, high-resolution rasterization, or GPU-accelerated workloads. The mobile RTX 5070, with its 50 W power envelope and integrated form factor, is the pick for portable systems where the 250 W desktop card cannot physically fit. The mobile part still outperforms several older desktop flagships in the database, including the NVIDIA GeForce RTX 3070 Ti and RTX 2080 Ti, but it trails its desktop sibling by a wide margin in every test category.

Where Each One Wins

The desktop RTX 5070 wins every single head-to-head benchmark in the database. Its largest advantages appear in compute-heavy workloads: PassMark GPU Compute shows a 90.7% lead, and Geekbench Vulkan shows a 53% lead. These results indicate the desktop card's higher shading unit count, faster clock speeds, and wider memory bus translate directly into superior throughput for parallel processing tasks.

The desktop part also dominates in legacy DirectX tests. PassMark DirectX 9 shows a 49.5% advantage, DirectX 11 shows 44.3%, and DirectX 10 shows 39.5%. Even the smallest lead, PassMark DirectX 12 at 16.1%, remains substantial. The mobile RTX 5070 has no benchmark where it records a win, but its data shows it delivers playable performance for its power class. Its PassMark G3D score of 20,355 places it within 0.1% of the RTX 3070 Ti's average score in the database, and it edges the RTX 2080 Ti by 0.5%.

For 2D workloads, the desktop card leads PassMark G2D by 45.6%, scoring 1,305 versus 896. The desktop GPU's pixel rate of 201.0 GPixel/s versus 68.40 GPixel/s on mobile further confirms its advantage in fill-rate-bound scenarios.

Architecture Differences

Both GPUs use the Blackwell 2.0 architecture and TSMC's 5 nm process, but they are different chips. The desktop RTX 5070 uses the GB205 die with 31,100 million transistors on a 263 mm² die, while the mobile RTX 5070 uses the GB206 die with 21,900 million transistors on a 181 mm² die. Transistor density is similar, 118.3M per mm² for desktop versus 121.0M per mm² for mobile, but the desktop chip packs roughly 42% more transistors overall.

The desktop card has 6,144 shading units, 192 texture mapping units, and 80 raster operations units. The mobile part has 4,608 shading units, 144 TMUs, and 48 ROPs. Ray tracing cores number 48 on desktop versus 36 on mobile, and tensor cores number 192 versus 144. Clock speeds diverge sharply: the desktop GPU runs at a 2,325 MHz base and 2,512 MHz boost, while the mobile chip runs at 907 MHz base and 1,425 MHz boost. These clock and core-count differences produce a large throughput gap: the desktop card delivers 30.87 TFLOPS FP32, while the mobile part delivers 13.13 TFLOPS.

Memory configurations also differ. The desktop RTX 5070 uses 12 GB of GDDR7 on a 192-bit bus with 672.0 GB/s bandwidth. The mobile version uses 8 GB of GDDR7 on a 128-bit bus with 384.0 GB/s bandwidth. Memory clocks are 1750 MHz (28 Gbps effective) on desktop versus 1500 MHz (24 Gbps effective) on mobile. The desktop card is dual-slot with a 16-pin power connector and a 600 W suggested PSU, while the mobile part is integrated (IGP) with no power connector and a 50 W TDP.
