NVIDIA H20 vs NVIDIA RTX 5000 Mobile Ada Generation Comparison

Head-to-Head Benchmarks

The recorded data shows that the NVIDIA RTX 5000 Mobile Ada Generation holds the only available benchmark score in the database, while the NVIDIA H20 has no recorded benchmark results. The RTX 5000 Mobile scores 3596 points in the 3DMark Steel Nomad DX12 test. This places the mobile GPU at the 21st percentile among all GPUs in the database, meaning roughly 79 percent of recorded GPUs score higher.

The nearest rivals for the RTX 5000 Mobile provide context for this result. The NVIDIA GeForce GT 545 averages 3594 points, just 0.1 percent behind the RTX 5000 Mobile. The NVIDIA GeForce GT 735M scores 3616 points, 0.6 percent ahead. The NVIDIA GeForce GTX 1050 records 3629 points, 0.9 percent ahead. The AMD Radeon HD 6770 achieves 3649 points, 1.5 percent ahead. These deltas are minimal, grouping the RTX 5000 Mobile with older desktop and mobile parts from previous generations in this specific DirectX 12 workload.

The H20 has no benchmark entries in the database, so direct numeric comparison between the two cards is not possible. The head-to-head benchmark array is empty, and the win counts for both items stand at zero. What the data does show is a stark contrast in positioning: the H20 sits at the 50th percentile while the RTX 5000 Mobile sits at the 21st percentile. However, this percentile gap should not be read as a performance ranking because the H20's percentile is derived from zero recorded benchmark scores, meaning it reflects an unmeasured default position rather than an observed result.

In terms of raw computational throughput, the specification sheets tell a different story than the benchmark percentile. The H20 delivers 39.54 TFLOPS of FP32 compute, while the RTX 5000 Mobile delivers 41.15 TFLOPS. The mobile part is ahead by roughly 1.61 TFLOPS in FP32, a margin of about 4 percent. In FP16, the H20 reaches 79.07 TFLOPS using a 2:1 ratio, while the RTX 5000 Mobile reaches 41.15 TFLOPS at a 1:1 ratio. The H20 doubles its FP32 rate in FP16, whereas the mobile Ada part does not, giving the H20 a significant advantage in mixed-precision workloads that leverage FP16 acceleration.

Texture and pixel throughput also favor the RTX 5000 Mobile. The H20 achieves 47.52 GPixel/s of pixel fill rate and 617.8 GTexel/s of texture fill rate. The RTX 5000 Mobile achieves 236.9 GPixel/s and 643.0 GTexel/s. The pixel rate difference is substantial: the mobile GPU delivers nearly five times the pixel throughput of the H20. Texture rate is closer, with the RTX 5000 Mobile ahead by 25.2 GTexel/s, roughly 4 percent.

Memory bandwidth tells the opposite story. The H20 features HBM3 memory with a 6144-bit bus, delivering 4.03 TB/s. The RTX 5000 Mobile uses GDDR6 on a 256-bit bus, delivering 576.0 GB/s. The H20's bandwidth advantage is roughly 7 times that of the mobile part, a decisive difference for memory-bound workloads.

Architecture Differences

The H20 uses the GH100 chip built on Hopper architecture, while the RTX 5000 Mobile uses the AD103 chip built on Ada Lovelace architecture. Both chips are manufactured by TSMC on a 5 nm process node, but the transistor counts diverge sharply. The GH100 packs 80,000 million transistors on an 814 mm² die, resulting in a transistor density of 98.3 million per mm². The AD103 contains 45,900 million transistors on a 379 mm² die, giving a higher density of 121.1 million per mm². The H20's die is more than twice the physical size of the mobile GPU's die, but the Ada chip achieves tighter packing.

The H20 belongs to the Server Hopper generation, with no series designation. The RTX 5000 Mobile belongs to the GeForce 50-series and the Ada-MW generation. The H20's predecessor is Server Ada and its successor is Server Blackwell. The RTX 5000 Mobile's predecessor is Ampere-MW and its successor is Blackwell-MW.

Shading unit counts are close: the H20 has 9984 shading units, while the RTX 5000 Mobile has 9728. Texture mapping units stand at 312 for the H20 and 304 for the mobile part. Raster operation units differ dramatically: the H20 has only 24 ROPs, while the RTX 5000 Mobile has 112. This explains the large pixel rate advantage for the mobile GPU.

Tensor core counts are 312 for the H20 and 304 for the RTX 5000 Mobile, nearly identical. The RTX 5000 Mobile also includes 76 dedicated ray tracing cores, while the H20 lists no RT core count. The H20 reports no API support for DirectX, OpenGL, or Vulkan, while the RTX 5000 Mobile supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The H20 is a server compute accelerator with no display outputs, while the RTX 5000 Mobile has display outputs described as portable device dependent.

Memory configurations diverge completely. The H20 carries 96 GB of HBM3 across a 6144-bit interface at 4.03 TB/s. The RTX 5000 Mobile carries 16 GB of GDDR6 across a 256-bit interface at 576.0 GB/s. The H20's memory clock is 1313 MHz with 5.3 Gbps effective data rate, while the RTX 5000 Mobile's memory clock is 2250 MHz with 18 Gbps effective.

Power and physical specifications separate the two further. The H20 consumes 500 W TDP with a suggested power supply of 900 W, and mounts as an SXM module. The RTX 5000 Mobile consumes 120 W TDP, uses no external power connectors, and is an integrated graphics processor (IGP). The H20 connects via PCIe 5.0 x16, while the RTX 5000 Mobile uses PCIe 4.0 x16.

Clock behavior differs by design. The H20 runs at a base clock of 1830 MHz and a boost of 1980 MHz. The RTX 5000 Mobile runs at 1425 MHz base and 2115 MHz boost. The mobile part boosts higher, but the H20 maintains a higher base clock.

The Verdict

The data presents two fundamentally different products. The H20 is a server accelerator built for compute density and massive memory capacity, with 96 GB of HBM3 and 4.03 TB/s bandwidth, but it lacks display outputs and graphics API support. The RTX 5000 Mobile is a laptop-class GPU with full graphics API support, ray tracing cores, and a much higher pixel rate, but it carries only 16 GB of memory and a fraction of the bandwidth.

The RTX 5000 Mobile has the only recorded benchmark score: 3596 in 3DMark Steel Nomad DX12, placing it at the 21st percentile. Its nearest rivals are all within 1.5 percent, indicating that this mobile GPU performs at a level comparable to older desktop parts like the GeForce GTX 1050 and AMD Radeon HD 6770 in that specific test. The H20 has no recorded benchmarks, so its 50th percentile position is not evidence of measured performance.

For FP32 compute, the RTX 5000 Mobile leads with 41.15 TFLOPS versus 39.54 TFLOPS. For FP16, the H20 leads with 79.07 TFLOPS versus 41.15 TFLOPS. The H20's FP16 advantage stems from its 2:1 FP16 to FP32 ratio, while the RTX 5000 Mobile runs FP16 at a 1:1 ratio.

The choice between these GPUs depends entirely on workload. The H20 suits server deployments requiring large memory pools, high bandwidth, and FP16 acceleration. The RTX 5000 Mobile suits graphics workloads, ray tracing, and applications needing display output and standard graphics APIs. Neither part replaces the other.

Where Each One Wins

The H20 wins in memory capacity, bandwidth, and FP16 throughput. Its 96 GB HBM3 pool and 4.03 TB/s bandwidth dominate the RTX 5000 Mobile's 16 GB GDDR6 and 576.0 GB/s. The H20's 79.07 TFLOPS FP16 performance doubles its FP32 rate, making it suited for workloads that exploit reduced precision, such as AI inference and training that rely on FP16 accumulation. The H20 also carries a higher base clock at 1830 MHz and a wider memory bus at 6144 bit.

The RTX 5000 Mobile wins in pixel throughput, FP32 compute, graphics API support, and ray tracing. Its 236.9 GPixel/s pixel rate is roughly 5 times the H20's 47.52 GPixel/s. Its 41.15 TFLOPS FP32 exceeds the H20 by 1.61 TFLOPS. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the H20 reports no API support. The 76 ray tracing cores enable hardware-accelerated ray tracing, a feature absent from the H20's spec sheet. The mobile part also boosts to 2115 MHz, higher than the H20's 1980 MHz boost.

The RTX 5000 Mobile holds the only measured benchmark result: 3596 in 3DMark Steel Nomad DX12. The H20 has no recorded benchmarks, so any performance comparison must rely on specification analysis rather than observed scores.

For a server environment requiring massive memory and bandwidth with FP16 acceleration, the H20 is the applicable part. For a mobile workstation needing graphics output, ray tracing, and standard API compatibility, the RTX 5000 Mobile is the applicable part. The two GPUs serve disjoint markets, and the recorded data does not support using either one in the other's intended role.
