NVIDIA GeForce RTX 5070 Mobile vs NVIDIA H20 NVL16 Comparison

The Verdict

The NVIDIA GeForce RTX 5070 Mobile and the NVIDIA H20 NVL16 serve entirely different purposes, and the recorded data confirms this split. The RTX 5070 Mobile is an active mobile graphics processor with a full suite of benchmark results, placing it in the 75th percentile of all GPUs. The H20 NVL16 is a server accelerator with no direct benchmark scores in the database, meaning its performance cannot be quantified against the mobile part. The RTX 5070 Mobile is the only option for consumers seeking a tested, general-purpose graphics solution with DirectX, OpenGL, and Vulkan support. The H20 NVL16 is a high-memory server module with a massive 96 GB HBM3 pool and a 400 W TDP, clearly oriented toward data center workloads rather than client-side rendering. The verdict is straightforward: the RTX 5070 Mobile for any measurable graphics task, the H20 NVL16 only for server deployments where its memory capacity and compute throughput are the priority.

Architecture Differences

The two processors come from different architectural families. The RTX 5070 Mobile uses Blackwell 2.0, built on the GB206 chip, while the H20 NVL16 uses Hopper, built on the GH100 chip. Both are fabricated on a 5 nm process at TSMC, but the similarities end there. The RTX 5070 Mobile has 21,900 million transistors on a 181 mm² die, yielding a transistor density of 121.0 million per mm². The H20 NVL16 packs 80,000 million transistors on an 814 mm² die, with a lower density of 98.3 million per mm². The larger chip and higher transistor count give the H20 NVL16 substantially more raw hardware resources.

The RTX 5070 Mobile belongs to the GeForce 50 Mobile generation, with a release date of April 14, 2025, and succeeds the GeForce 40 Mobile series. The H20 NVL16 is part of the Server Hopper (Hxx) generation, released September 1, 2025, succeeding Server Ada and preceding Server Blackwell. The mobile part is an IGP (integrated graphics processor) with no power connectors and a 50 W TDP, designed to be embedded in laptops. The server part is an SXM Module with a 400 W TDP and an 800 W suggested PSU, designed for data center chassis.

The RTX 5070 Mobile includes 36 RT cores for ray tracing, while the H20 NVL16 records no RT core count in the database. The mobile part also has full graphics API support: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The H20 NVL16 lists N/A for all graphics APIs, reinforcing its role as a compute accelerator without display output (its display output field reads "No outputs"). The RTX 5070 Mobile relies on GDDR7 memory, while the H20 NVL16 uses HBM3. Clock behavior differs significantly: the RTX 5070 Mobile runs a 907 MHz base and 1425 MHz boost, whereas the H20 NVL16 runs a much higher 1830 MHz base and 1980 MHz boost.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two processors, and the wins counters show 0 for both. The H20 NVL16 has an empty benchmark array, an average benchmark score of 0, and no nearest rivals. This means every measurable performance figure in the database belongs solely to the RTX 5070 Mobile. The mobile GPU delivers a Geekbench OpenCL score of 122,238 and a Geekbench Vulkan score of 116,960. In Passmark tests, it scores 129 in DirectX 10, 192 in DirectX 11, 93 in DirectX 12, and 214 in DirectX 9. Its Passmark G2D score is 896, G3D score is 20,355, and GPU compute score is 8,279. The average benchmark score across all tests is 29,928.

The RTX 5070 Mobile's nearest rivals in the database are all desktop or older mobile parts. It sits 0.1% behind the NVIDIA GeForce RTX 3070 Ti (which averages 29,945), 0.5% ahead of the NVIDIA GeForce RTX 2080 Ti (29,783), 0.6% behind the AMD Radeon RX 6800 (30,095), and 1.7% behind the AMD Radeon RX 6700 (30,433). These deltas are narrow, indicating the RTX 5070 Mobile performs in the same tier as those established GPUs despite being a 50 W mobile part. The H20 NVL16 has no comparable benchmark data, so no head-to-head comparison can be drawn from the recorded measurements.

Specification Differences

The specification split between the two parts is stark. The RTX 5070 Mobile has 4,608 shading units, 144 TMUs, and 48 ROPs. The H20 NVL16 has 9,984 shading units, 312 TMUs, but only 24 ROPs. The H20 NVL16's ROP count is half the mobile part's, which aligns with its compute-focused design. The H20 NVL16 has 312 tensor cores compared to 144 on the RTX 5070 Mobile. The RTX 5070 Mobile has 36 RT cores; the H20 NVL16 has none recorded.

Memory configurations diverge completely. The RTX 5070 Mobile has 8 GB of GDDR7 on a 128-bit bus, delivering 384.0 GB/s of bandwidth. The H20 NVL16 has 96 GB of HBM3 on a 6144-bit bus, delivering 4.03 TB/s of bandwidth, which is roughly 10.5 times the bandwidth of the mobile part. The H20 NVL16's memory clock is 1313 MHz with 5.3 Gbps effective, while the RTX 5070 Mobile's memory clock is 1500 MHz with 24 Gbps effective. The server part's bandwidth advantage comes from its enormous bus width.

Compute throughput figures reflect the server part's dominance. The H20 NVL16 delivers 39.54 TFLOPS FP32 and 79.07 TFLOPS FP16 (2:1 ratio). The RTX 5070 Mobile delivers 13.13 TFLOPS FP32 and 13.13 TFLOPS FP16 (1:1 ratio). The H20 NVL16 is roughly 3 times ahead in FP32 and 6 times ahead in FP16. Texture and pixel rates follow the same pattern: the H20 NVL16 reaches 617.8 GTexel/s versus 205.2 GTexel/s on the mobile part, though the mobile part has a higher pixel rate at 68.40 GPixel/s versus 47.52 GPixel/s on the server part, a result of the H20 NVL16's low ROP count.

Power and physical specifications also differ. The RTX 5070 Mobile has a 50 W TDP, no power connectors, and is an IGP. The H20 NVL16 has a 400 W TDP, no listed power connectors, and an 800 W suggested PSU. Both use PCIe 5.0 x16 interfaces. The mobile part's display outputs are "Portable Device Dependent," while the server part has no outputs. The mobile part launched in April 2025, the server part in September 2025.

Where Each One Wins

The RTX 5070 Mobile wins in every area where benchmark data exists. It has a Geekbench OpenCL score of 122,238 and a Geekbench Vulkan score of 116,960, plus Passmark scores across DirectX 10, 11, 12, and 9, with its strongest Passmark result being 20,355 in G3D. It is the only one of the two with any graphics API support, any display output capability, and any RT core count. It also has a higher pixel rate at 68.40 GPixel/s versus 47.52 GPixel/s on the H20 NVL16, and its GDDR7 memory runs at a higher effective speed of 24 Gbps versus 5.3 Gbps on the HBM3 of the server part. Its transistor density is higher at 121.0M per mm² versus 98.3M per mm², and its 50 W TDP makes it suitable for portable devices.

The H20 NVL16 wins in raw compute and capacity. It has 39.54 TFLOPS FP32 and 79.07 TFLOPS FP16, both far above the RTX 5070 Mobile's 13.13 TFLOPS in each precision. Its 96 GB HBM3 memory is 12 times the capacity of the mobile part's 8 GB, and its 4.03 TB/s bandwidth is over 10 times higher. It has 9,984 shading units versus 4,608, 312 TMUs versus 144, and 312 tensor cores versus 144. Its texture rate of 617.8 GTexel/s is roughly 3 times the mobile part's 205.2 GTexel/s. The H20 NVL16 also has a higher boost clock at 1980 MHz versus 1425 MHz, and a higher base clock at 1830 MHz versus 907 MHz.

The usage split is clear from the data. The RTX 5070 Mobile is the choice for any workload requiring graphics output, DirectX, OpenGL, or Vulkan support, or ray tracing, and it delivers desktop-class performance in a 50 W mobile package. The H20 NVL16 is the choice for server deployments where 96 GB of HBM3, 4.03 TB/s of bandwidth, 79.07 TFLOPS of FP16 compute, and 312 tensor cores are the deciding factors, and where graphics output is not needed. The two parts do not compete; the database shows one is a client graphics processor with verified scores, the other is a server compute accelerator with no recorded benchmarks.
