Both chips share nearly identical transistor counts, with the AD103 containing 45,900 million transistors and the GB203 containing 45,600 million, and similar die sizes of 379 mm² and 378 mm² respectively. The transistor density is 121.1M per mm² for the AD103 and 120.6M per mm² for the GB203, a negligible difference.

The shading unit count differs substantially. The RTX 4070 AD103 has 5,888 shading units, while the RTX 5090 Mobile has 10,496, a 78% increase. Texture mapping units scale from 184 to 328, and raster operation units from 64 to 112. Ray tracing cores increase from 46 to 82, and tensor cores from 184 to 328. These counts directly influence the pixel and texture rates: the RTX 4070 AD103 achieves 158.4 GPixel/s and 455.4 GTexel/s, while the RTX 5090 Mobile achieves 169.7 GPixel/s and 496.9 GTexel/s.

Clock speeds follow opposite patterns. The RTX 4070 AD103 runs at a 1920 MHz base and 2475 MHz boost, while the RTX 5090 Mobile runs at a 990 MHz base and 1515 MHz boost. The desktop card's higher clocks compensate partially for its lower unit counts, but the mobile part's much larger execution resource pool still yields higher aggregate throughput. The memory clock also differs, with the RTX 4070 AD103 at 1313 MHz (21 Gbps effective) and the RTX 5090 Mobile at 1750 MHz (28 Gbps effective).

The bus interface advances from PCIe 4.0 x16 to PCIe 5.0 x16. Display outputs differ as well: the RTX 4070 AD103 provides 1x HDMI 2.1 and 3x DisplayPort 1.4a, while the RTX 5090 Mobile's outputs are listed as portable device dependent, reflecting its mobile integration. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Specification Differences

The two GPUs differ across nearly every specification field. Memory capacity doubles from 12 GB to 24 GB, and memory type changes from GDDR6X to GDDR7. Bus width expands from 192 bit to 256 bit, and bandwidth increases from 504.2 GB/s to 896.0 GB/s.

Compute resources show the largest gaps. Shading units go from 5,888 to 10,496, TMUs from 184 to 328, ROPs from 64 to 112, RT cores from 46 to 82, and tensor cores from 184 to 328. FP32 and FP16 throughput both rise from 29.15 TFLOPS to 31.80 TFLOPS.

Physical specifications diverge sharply due to form factor. The RTX 4070 AD103 is a dual-slot desktop card measuring 240 mm in length, 110 mm in height, and 40 mm in width, with a 200 W TDP and a single 16-pin power connector requiring a 550 W suggested PSU. The RTX 5090 Mobile is an IGP (integrated graphics processor) with no listed dimensions, no power connector, and a 95 W TDP. The desktop card has a launch MSRP of 599 USD, while the mobile part has no listed launch MSRP.

Production status and release timing also differ. The RTX 4070 AD103 is end-of-life, released on 2024-02-29, with the GeForce 30 series as its predecessor and GeForce 50 as its successor. The RTX 5090 Mobile is active, released on 2025-03-26, with GeForce 40 Mobile as its predecessor and no listed successor.

Where Each One Wins

The RTX 5090 Mobile wins on raw computational throughput. Its FP32 output of 31.80 TFLOPS exceeds the RTX 4070 AD103's 29.15 TFLOPS, and its texture rate of 496.9 GTexel/s surpasses the desktop card's 455.4 GTexel/s. The pixel rate also favors the mobile part at 169.7 GPixel/s versus 158.4 GPixel/s. Memory bandwidth is decisively higher on the RTX 5090 Mobile at 896.0 GB/s compared to 504.2 GB/s, which benefits workloads that are memory-bandwidth bound, such as high-resolution texturing and large dataset compute tasks.

The RTX 5090 Mobile also wins on capacity and connectivity generation. Its 24 GB frame buffer doubles the RTX 4070 AD103's 12 GB, and its GDDR7 memory type is newer than GDDR6X. The PCIe 5.0 x16 interface provides twice the link generation of the desktop card's PCIe 4.0 x16, which matters for data transfer between the GPU and system memory in compute scenarios.

The RTX 4070 AD103 wins on clock speed. Its 1920 MHz base and 2475 MHz boost clocks are substantially higher than the RTX 5090 Mobile's 990 MHz base and 1515 MHz boost. For workloads that scale with clock frequency rather than raw unit count, such as lightly threaded single-draw operations or latency-sensitive tasks, the desktop card's higher clocks provide an advantage. The RTX 4070 AD103 also wins on power delivery simplicity in a desktop context, with a standard dual-slot form factor and defined display outputs, whereas the mobile part's display outputs depend on the host device.

The RTX 4070 AD103 holds an advantage in the 50th percentile ranking versus the RTX 5090 Mobile's 84th percentile, but this reflects the mobile card's measured benchmark presence rather than a direct comparison. The desktop card has no benchmark entries in the database, so its percentile is based on specification-based placement rather than recorded performance.

The Verdict

The recorded data indicates that the NVIDIA GeForce RTX 5090 Mobile is the stronger performer on nearly every measurable specification. Its 24 GB GDDR7 memory with 896.0 GB/s bandwidth, 10,496 shading units, and 31.80 TFLOPS FP32 throughput position it well above the RTX 4070 AD103's 12 GB GDDR6X memory with 504.2 GB/s bandwidth, 5,888 shading units, and 29.15 TFLOPS. The mobile card's 84th percentile ranking among all GPUs, supported by an average benchmark score of 45,152, confirms that it delivers competitive performance in real workloads, sitting within 2% of several desktop-class rivals.

The RTX 5090 Mobile is the appropriate choice for users who need maximum compute throughput, large memory capacity for high-resolution assets or machine learning workloads, and the latest PCIe 5.0 interface, all within a 95 W power envelope that suits mobile integration. Its benchmark scores across PassMark, Geekbench, and 3DMark workloads demonstrate consistent strength in both compute and graphics tasks.

The RTX 4070 AD103 remains relevant for users who prioritize higher clock speeds and a conventional desktop form factor with fixed display outputs. Its 2475 MHz boost clock exceeds the mobile part's 1515 MHz boost, and its dual-slot design with a 16-pin connector and 550 W suggested PSU fits standard desktop builds. However, its end-of-life production status, smaller memory subsystem, and lower unit counts make it the weaker option in raw performance terms.

The data shows a clear generational and performance tier separation. The RTX 5090 Mobile belongs to the active GeForce 50 generation and outperforms the RTX 4070 AD103 in every throughput metric recorded in the database. Users selecting between these two parts should base their decision on form factor requirements and clock-speed sensitivity, with the RTX 5090 Mobile delivering superior compute and memory performance and the RTX 4070 AD103 offering higher clocks and desktop-specific connectivity.
