NVIDIA GeForce RTX 5070 Mobile vs NVIDIA H20 Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the NVIDIA GeForce RTX 5070 Mobile and the NVIDIA H20. The head-to-head benchmark array is empty, and the win counters for both parts read zero. This absence of recorded comparative tests is structurally significant: the two products occupy entirely different segments, with the RTX 5070 Mobile aimed at portable devices and the H20 built as a server accelerator module.

What can be analyzed is the standalone benchmark profile of the RTX 5070 Mobile, since the H20 has no recorded benchmark scores in the database. The RTX 5070 Mobile posts an average benchmark score of 29,928 across its nine recorded tests. Its percentile ranking among all GPUs is 75, meaning it sits above three-quarters of the tracked graphics processors. The nearest rivals in the database, based on average score, are the NVIDIA GeForce RTX 3070 Ti at 29,945 (a delta of -0.1%), the NVIDIA GeForce RTX 2080 Ti at 29,783 (a delta of +0.5%), the AMD Radeon RX 6800 at 30,095 (a delta of -0.6%), and the AMD Radeon RX 6700 at 30,433 (a delta of -1.7%). These deltas are all within 1.7 percentage points, which places the RTX 5070 Mobile in a tight performance cluster with those desktop-class parts from previous generations.

Looking at individual benchmark disciplines, the RTX 5070 Mobile shows a varied profile. Its strongest recorded result is in Geekbench OpenCL, where it scores 122,238. The Geekbench Vulkan result is 116,960. In Passmark tests, the highest score is in DirectX 9 at 214, followed by DirectX 11 at 192, DirectX 10 at 129, and DirectX 12 at 93. The Passmark 2D score is 896, while the 3D score is 20,355. The GPU compute score in Passmark is 8,279.

The H20, by contrast, has no benchmarks recorded in the database. Its average benchmark score is listed as 0, and its percentile ranking is 50, which appears to be a default value rather than a measured position. The nearest rivals array for the H20 is empty. This means no comparative statistical statements can be made about the H20's measured performance relative to any other GPU in the database.

The RTX 5070 Mobile's benchmark results indicate a part that delivers consistent DirectX 11 and DirectX 9 performance in legacy API workloads, while its Geekbench scores suggest strong compute-oriented capabilities. The delta values against its nearest rivals show that the RTX 5070 Mobile is statistically indistinguishable from the RTX 3070 Ti, with a difference of only one-tenth of one percent. It is half a percent ahead of the RTX 2080 Ti, and it trails the RX 6800 by 0.6% and the RX 6700 by 1.7%. These margins are small enough that real-world application differences would likely outweigh the synthetic benchmark gaps.

Where Each One Wins

The RTX 5070 Mobile wins in every category where the database has recorded data, simply because the H20 has no recorded benchmark scores. The RTX 5070 Mobile's wins are measurable across OpenCL, Vulkan, and all six Passmark tests. The H20 has zero recorded wins in the database.

For the RTX 5070 Mobile, the win profile is split between legacy API workloads and modern compute interfaces. In Passmark DirectX 9, it scores 214, which is its highest Passmark result. DirectX 11 follows at 192, while DirectX 10 and DirectX 12 score 129 and 93 respectively. This pattern suggests that the RTX 5070 Mobile performs relatively better in older DirectX APIs than in the newest one, at least in the Passmark suite. The 2D score of 896 and 3D score of 20,355 indicate that the part is substantially stronger in 3D rendering than in 2D operations, which is typical for a dedicated graphics processor.

The Geekbench OpenCL score of 122,238 versus the Vulkan score of 116,960 shows a 4.5% advantage for OpenCL in that suite. This difference may reflect driver optimization or workload characteristics rather than raw hardware capability.

The H20's lack of recorded benchmarks means it cannot be credited with any wins in this database. Its role as a server accelerator with no display outputs and no recorded API support (DirectX, OpenGL, and Vulkan are all listed as N/A) places it outside the consumer benchmark ecosystem entirely. The database records no measured performance for this part, so any win allocation would be speculative.

Architecture Differences

The two GPUs differ fundamentally in architecture, chip design, and intended deployment. The RTX 5070 Mobile uses the GB206 chip built on the Blackwell 2.0 architecture, fabricated on a 5 nm process at TSMC. The H20 uses the GH100 chip built on the Hopper architecture, also fabricated on a 5 nm process at TSMC. Both share the same foundry and process node, but the silicon implementations diverge dramatically.

The transistor counts show the scale difference. The GB206 in the RTX 5070 Mobile contains 21,900 million transistors on a die size of 181 mm², yielding a transistor density of 121.0 million per mm². The GH100 in the H20 contains 80,000 million transistors on a die size of 814 mm², with a transistor density of 98.3 million per mm². The H20's die is 4.5 times larger in area and holds 3.65 times more transistors. The RTX 5070 Mobile has the higher transistor density, which reflects a more compact integration.

Clock speeds differ substantially. The RTX 5070 Mobile runs at a base clock of 907 MHz and a boost clock of 1425 MHz. The H20 runs at a base clock of 1830 MHz and a boost clock of 1980 MHz. The H20's base clock is 102% higher than the RTX 5070 Mobile's base, and its boost clock is 39% higher. Memory clocks also diverge: the RTX 5070 Mobile uses 1500 MHz with 24 Gbps effective data rate, while the H20 uses 1313 MHz with 5.3 Gbps effective. The H20's lower memory clock is offset by its HBM3 memory type and vastly wider bus.

Memory configuration is a major differentiator. The RTX 5070 Mobile has 8 GB of GDDR7 memory on a 128-bit bus, delivering 384.0 GB/s of bandwidth. The H20 has 96 GB of HBM3 memory on a 6144-bit bus, delivering 4.03 TB/s of bandwidth. The H20 has 12 times the memory capacity, 48 times the bus width, and approximately 10.5 times the memory bandwidth.

Compute resources also scale in the H20's favor. The RTX 5070 Mobile has 4,608 shading units, 144 texture mapping units, 48 raster output units, 36 ray tracing cores, and 144 tensor cores. The H20 has 9,984 shading units, 312 texture mapping units, 24 raster output units, no listed ray tracing cores, and 312 tensor cores. The H20 has 2.17 times the shading units, 2.17 times the texture units, and 2.17 times the tensor cores. The RTX 5070 Mobile has double the raster output units, 48 versus 24. The H20's lack of ray tracing cores is notable for a server part that is not designed for consumer graphics workloads.

Rates and throughput values reflect the architectural split. The RTX 5070 Mobile achieves a pixel rate of 68.40 GPixel/s and a texture rate of 205.2 GTexel/s. The H20 achieves a pixel rate of 47.52 GPixel/s and a texture rate of 617.8 GTexel/s. The H20 has 3 times the texture rate but 30% lower pixel rate, consistent with its lower ROP count. Floating point performance shows the H20's advantage: 39.54 TFLOPS FP32 versus 13.13 TFLOPS for the RTX 5070 Mobile. In FP16, the H20 delivers 79.07 TFLOPS with a 2:1 ratio, while the RTX 5070 Mobile delivers 13.13 TFLOPS with a 1:1 ratio. The H20 is 3 times faster in FP32 and 6 times faster in FP16.

Power and physical specifications differ as expected for their form factors. The RTX 5070 Mobile has a TDP of 50 W and is an IGP (integrated graphics processor) with no power connectors and portable-device-dependent display outputs. The H20 has a TDP of 500 W, uses an SXM module slot, has no display outputs, and requires a 900 W suggested PSU. Both use a PCIe 5.0 x16 bus interface. The RTX 5070 Mobile supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4; the H20 lists N/A for all three APIs.
