NVIDIA GeForce RTX 4070 AD103 vs NVIDIA RTX 3000 Mobile Ada Generation Comparison

Head-to-Head Benchmarks

The recorded data for both parts is empty in the benchmark database, meaning no direct performance measurements are available for either the NVIDIA GeForce RTX 4070 AD103 or the NVIDIA RTX 3000 Mobile Ada Generation. Both GPUs hold identical percentile positions at 50.0, indicating they sit at the median of all recorded graphics processors. With no benchmark scores logged, the average benchmark score for each is zero, and the nearest rivals lists are empty. This absence of measured data prevents any quantitative comparison of frame rates, render times, or compute throughput between the two parts.

The database does, however, provide extensive architectural and specification data that can be used to project relative capability. The RTX 4070 AD103 delivers a theoretical FP32 throughput of 29.15 TFLOPS, while the RTX 3000 Mobile Ada Generation produces 15.62 TFLOPS. That represents a raw compute advantage of roughly 1.87x for the desktop part, a figure derived directly from the recorded FP32 values. Similarly, the texture rate for the RTX 4070 AD103 is 455.4 GTexel/s versus 244.1 GTexel/s for the mobile chip, a 1.87x lead. Pixel fill rates show a wider gap: 158.4 GPixel/s versus 81.36 GPixel/s, a 1.95x difference.

Memory bandwidth also clearly separates the two. The RTX 4070 AD103 uses a 192-bit bus with GDDR6X memory at 21 Gbps effective, yielding 504.2 GB/s. The RTX 3000 Mobile Ada Generation relies on a 128-bit bus with GDDR6 at 16 Gbps effective, yielding 256.0 GB/s. The desktop card delivers exactly twice the memory bandwidth of the mobile part. These recorded figures indicate that, in any memory-bound workload, the RTX 4070 AD103 should hold a substantial advantage, though no measured scores confirm this in practice.

Architecture Differences

Both GPUs are built on the Ada Lovelace architecture and fabricated by TSMC on a 5 nm process node. The transistor density is nearly identical: 121.1M per mm² for the AD103 chip and 121.8M per mm² for the AD106 chip. The chips themselves differ significantly in scale. The RTX 4070 AD103 uses the AD103 die, which measures 379 mm² and contains 45,900 million transistors. The RTX 3000 Mobile Ada Generation uses the AD106 die, measuring 188 mm² with 22,900 million transistors. The desktop chip is roughly twice the physical size and holds exactly double the transistor count.

The core configurations diverge across every processing unit type. The RTX 4070 AD103 features 5,888 shading units, 184 texture mapping units, and 64 ROPs. The mobile part has 4,608 shading units, 144 TMUs, and 48 ROPs. Ray tracing cores number 46 on the desktop card versus 36 on the mobile chip. Tensor cores follow the same pattern: 184 on the RTX 4070 AD103 and 144 on the RTX 3000 Mobile Ada Generation. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, with identical FP16-to-FP32 ratios of 1:1.

Clock speeds differ substantially. The RTX 4070 AD103 runs at a base clock of 1920 MHz and a boost clock of 2475 MHz. The RTX 3000 Mobile Ada Generation operates at a base of 1395 MHz and a boost of 1695 MHz. The desktop part's boost clock is 780 MHz higher, a 46% increase over the mobile chip's boost figure. Power targets reflect the form factor difference: the desktop card has a TDP of 200 W, while the mobile part draws 115 W. The desktop card requires a 550 W suggested PSU and a single 16-pin power connector; the mobile GPU uses no power connectors and has no suggested PSU listed, as it is designed for integration into laptops.

The Verdict

The data indicates a clear hierarchy between these two Ada Lovelace GPUs, but the absence of measured benchmark scores means the verdict rests entirely on recorded specifications. The RTX 4070 AD103 is the more capable part on every compute metric: FP32 throughput is 1.87x higher, texture rate is 1.87x higher, pixel rate is 1.95x higher, and memory bandwidth is exactly 2.0x higher. It also carries 28% more shading units, 28% more TMUs, 33% more ROPs, 28% more RT cores, and 28% more tensor cores than the mobile chip.

The RTX 3000 Mobile Ada Generation, by contrast, is designed for a fundamentally different use case. Its 115 W TDP, IGP form factor, and lack of power connectors indicate integration into portable systems, while the RTX 4070 AD103's 200 W TDP, dual-slot cooler, and 16-pin connector reflect a desktop add-in card. The mobile part's smaller AD106 die at 188 mm² with 22,900 million transistors enables this lower power envelope, whereas the AD103 at 379 mm² with 45,900 million transistors delivers the higher performance ceiling.

For users selecting between a desktop workstation or gaming PC and a mobile workstation, the choice is dictated by form factor and power constraints. The RTX 4070 AD103 is the stronger performer on paper across all recorded metrics, and its launch MSRP of 599 USD positions it as a premium desktop component. The RTX 3000 Mobile Ada Generation, with no launch MSRP recorded, exists in the mobile market where physical size, cooling, and power draw are primary constraints. The desktop part is end-of-life, while the mobile part remains active in production, suggesting the mobile GPU still serves an ongoing market segment. No benchmark data exists to validate real-world performance, so the conclusion is strictly architectural: the RTX 4070 AD103 offers roughly double the memory bandwidth and nearly double the compute throughput, making it the more powerful option for any workload that can tolerate its desktop footprint and power requirements.
