Architecture Differences

Both GPUs belong to the GeForce 50-series and share the Blackwell 2.0 architecture, manufactured by TSMC on a 5 nm process. The fundamental silicon, however, diverges sharply. The RTX 5070 Mobile uses the GB206 chip, a smaller die at 181 mm², housing 21,900 million transistors. The RTX 5090 SE uses the GB202 chip, a much larger die at 750 mm², containing 92,200 million transistors. Transistor density is nearly identical: 121.0M per mm² for the mobile part versus 122.9M per mm² for the SE. This implies the scaling is driven by die size rather than process improvements.

Core counts reflect the hierarchy. The RTX 5070 Mobile has 4608 shading units, 144 texture mapping units, and 48 render output units. The RTX 5090 SE more than triples these: 14,080 shading units, 440 TMUs, and 160 ROPs. Ray tracing and tensor cores follow the same pattern. The mobile GPU has 36 RT cores and 144 tensor cores; the SE has 110 RT cores and 440 tensor cores. In raw throughput, the FP32 rate is 13.13 TFLOPS for the RTX 5070 Mobile versus 66.94 TFLOPS for the RTX 5090 SE. FP16 performance matches FP32 at a 1:1 ratio on both, meaning the same 13.13 and 66.94 TFLOPS figures apply.

Clock behavior differs substantially. The RTX 5070 Mobile runs at a 907 MHz base and 1425 MHz boost, which is low for a desktop part but typical for a low-power mobile GPU. The RTX 5090 SE runs at 1740 MHz base and 2377 MHz boost, a 66.8% higher boost clock. Memory clocks also diverge: the mobile part uses 1500 MHz with 24 Gbps effective, while the SE uses 1750 MHz with 28 Gbps effective. Both use GDDR7, but the bus widths create a larger bandwidth gap. The 128-bit bus on the RTX 5070 Mobile yields 384.0 GB/s; the 384-bit bus on the RTX 5090 SE yields 1.34 TB/s, a factor of roughly 3.5.

Power and physical design are starkly different. The RTX 5070 Mobile is an integrated graphics package (IGP) with a 50 W TDP, no power connectors, and portable-device-dependent display outputs. The RTX 5090 SE is a dual-slot discrete card, 267 mm long, 111 mm high, and 40 mm wide, with a 500 W TDP and a single 16-pin connector. The suggested power supply for the SE is 900 W. API support is identical: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, both over a PCIe 5.0 x16 interface.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the RTX 5070 Mobile and the RTX 5090 SE. The head-to-head field is empty, and the win counters for both sides are zero. The RTX 5090 SE has no benchmark scores at all, so no comparison can be drawn from recorded test data. The RTX 5070 Mobile, however, has nine separate scores that place it in context relative to other GPUs.

Geekbench scores for the RTX 5070 Mobile are 122,238 in OpenCL and 116,960 in Vulkan. Passmark tests show a different pattern. The DirectX 9 score is 214, DirectX 10 is 129, DirectX 11 is 192, and DirectX 12 is 93. The G2D score is 896, while the G3D score is 20,355. GPU compute via Passmark is 8,279. The average benchmark score across these entries is 29,928. This average places the RTX 5070 Mobile at the 75th percentile among all GPUs in the database.

The nearest rivals provide a baseline. The NVIDIA GeForce RTX 3070 Ti has an average score of 29,945, which is 0.1% higher than the RTX 5070 Mobile. The AMD Radeon RX 6800 averages 30,095, 0.6% higher. The AMD Radeon RX 6700 averages 30,433, 1.7% higher. The only rival the RTX 5070 Mobile beats is the NVIDIA GeForce RTX 2080 Ti, which averages 29,783, a 0.5% deficit. These deltas are small, all within 2 percentage points, indicating the RTX 5070 Mobile sits in a tight performance cluster around 30,000 points.

Because the RTX 5090 SE has no benchmark data, any statement about its measured performance would be unsupported. The recorded data allows only a specification-level analysis. The SE’s theoretical FP32 throughput is roughly 5.1 times that of the RTX 5070 Mobile (66.94 TFLOPS versus 13.13 TFLOPS). Its texture rate is 1,045.9 GTexel/s versus 205.2 GTexel/s, about 5.1 times higher. Pixel rate is 380.3 GPixel/s versus 68.40 GPixel/s, about 5.6 times higher. These figures come from the specification fields, not from benchmark runs.

Where Each One Wins

The RTX 5070 Mobile wins in the domain of portability and low power. Its 50 W TDP and IGP slot width mean it can be integrated directly into a laptop or compact device without external power connectors. The absence of a suggested PSU further indicates it draws from the host system’s existing power delivery. This makes it suitable for thin-and-light portable systems where discrete power cabling is impractical. Its smaller die, 181 mm², and lower transistor count, 21,900 million, also imply lower manufacturing cost per unit, though pricing data is not available for this part.

The RTX 5090 SE wins in every raw performance category listed in the specifications. It offers 5.1 times the FP32 throughput, 5.1 times the texture rate, and 5.6 times the pixel rate of the RTX 5070 Mobile. The memory subsystem is decisively larger: 24 GB versus 8 GB, 384-bit versus 128-bit, and 1.34 TB/s versus 384.0 GB/s. The higher boost clock, 2377 MHz versus 1425 MHz, and the larger core counts across all unit types give it a clear theoretical advantage for high-resolution rendering, ray tracing workloads, and compute tasks. The 110 RT cores versus 36 and 440 tensor cores versus 144 indicate a proportional lead in hardware-accelerated ray tracing and AI inference.

The RTX 5070 Mobile holds a measured advantage in the database’s benchmark records, but only because the RTX 5090 SE has no recorded scores. The mobile part’s average benchmark score of 29,928 places it at the 75th percentile of all GPUs, beating the RTX 2080 Ti by 0.5% and trailing the RTX 3070 Ti by 0.1%, the RX 6800 by 0.6%, and the RX 6700 by 1.7%. These results indicate the RTX 5070 Mobile performs at a level comparable to high-end desktop GPUs from previous generations, despite its low 50 W power envelope.

For use cases, the RTX 5070 Mobile fits systems where power efficiency and integration are the primary constraints. The 50 W TDP allows for fanless or low-noise designs, and the portable-device-dependent display outputs mean the manufacturer can route video signals flexibly. The 8 GB GDDR7 memory on a 128-bit bus is adequate for 1080p and moderate 1440p gaming, though the database does not provide frame-rate measurements. The RTX 5090 SE, with a 500 W TDP and a 900 W suggested PSU, targets desktop workstations and high-end gaming rigs where space, cooling, and power delivery are available. Its 24 GB memory and 1.34 TB/s bandwidth support large datasets, multi-monitor setups with three DisplayPort 2.1b outputs and one HDMI 2.1b, and sustained high-throughput compute.

The physical footprint reinforces the split. The RTX 5090 SE is 267 mm long, 111 mm tall, and 40 mm wide, a dual-slot card that requires a full-size chassis. The RTX 5070 Mobile has no listed dimensions, consistent with an integrated part soldered to a motherboard. The SE’s 1x 16-pin power connector and 500 W TDP demand a robust power supply, while the mobile part’s no-connector design eliminates that requirement. In short, the RTX 5070 Mobile wins on mobility and low power, and the RTX 5090 SE wins on raw specification strength and expandability, with no direct benchmark comparison available to settle measured performance differences.
